US podcast advertising revenue reached $2.862 billion in 2025, a 17.6% year-over-year increase reported by IAB and PwC in April 2026. That is 27.1 times the $105.7 million the category booked in 2015, and it now represents 34.1% of all US digital audio advertising — yet still under 1% of total internet ad spend.
Quick Answer
Podcast advertising in the United States is a $2.862 billion market growing at 17.6% a year, faster than digital audio overall (10.2%) and faster than the total internet advertising market (13.9%). Published host-read CPMs sit at $24–26 for 60-second spots against $12–15 programmatic. Axis Intelligence Research calculates the market yields $17.14 per monthly listener per year, and scores the category at 63.2 on the Podcast Ad Revenue Intensity (PARI™) Index.

How Big Is the Podcast Advertising Market in 2026?
The number to quote is $2.862 billion, and the number to understand is the one underneath it.
IAB and PwC’s full-year 2025 Internet Advertising Revenue Report, released in April 2026, puts US podcast advertising revenue at $2,862.2 million, a 17.6% gain over 2024. That was the thirtieth edition of the report, and it is the closest thing the category has to an audited number: PwC collects revenue directly from companies selling the advertising and supplements it with public filings.
Here is the full series, which is the part most coverage skips.
US Podcast Advertising Revenue by Year, 2015–2025
| Year | Revenue (US$ M) | YoY growth | Source |
|---|---|---|---|
| 2015 | 105.7 | — | IAB / PwC, FY2025 report |
| 2016 | 169.1 | 60.0% | IAB / PwC, FY2025 report |
| 2017 | 313.9 | 85.6% | IAB / PwC, FY2025 report |
| 2018 | 479.1 | 52.6% | IAB / PwC, FY2025 report |
| 2019 | 708.1 | 47.8% | IAB / PwC, FY2025 report |
| 2020 | 842.3 | 19.0% | IAB / PwC, FY2025 report |
| 2021 | 1,448.7 | 72.0% | IAB / PwC, FY2025 report |
| 2022 | 1,825.3 | 26.0% | IAB / PwC, FY2025 report |
| 2023 | 1,925.2 | 5.5% | IAB / PwC, FY2025 report |
| 2024 | 2,433.1 | 26.4% | IAB / PwC, FY2025 report |
| 2025 | 2,862.2 | 17.6% | IAB / PwC, FY2025 report |
Growth rates are computed by Axis Intelligence Research from the IAB revenue series and reproduce IAB’s own published growth labels to the nearest point.
Three phases sit in that column. The 2016–2019 land grab, when a small base made triple-digit percentages cheap. The 2023 stall at 5.5%, when the ad recession found podcasting and the “podcasting is recession-proof” thesis quietly died. And the 2024–2025 recovery, which added $508 million and then $429 million in absolute dollars — the two largest dollar increases in the category’s history, arriving in the same two years that its percentage growth was described as decelerating.
That distinction matters for anyone planning a 2027 budget. Percentage deceleration on a base 27 times larger than 2015 is not the same story as a slowdown.
Compound growth, calculated by Axis Intelligence Research from the IAB series: 39.1% annually over 2015–2025, 27.7% over 2020–2025, and 16.2% over 2022–2025. The trend line is flattening toward the mid-teens, which is roughly where the last two years actually landed.
Alex Rivera: The interesting thing about the 2023 dip is what it did to sell-through discipline. Ad load didn’t collapse — pricing did, and shows that had built their entire business on a single direct-response category found out how thin their advertiser base was. The 2025 number is healthier not because it is bigger but because the category mix behind it is wider.
How Fast Is Podcast Ad Revenue Growing Compared to Other Formats?
Podcasting outgrew every audio comparison and lost to video.
Against the same IAB/PwC full-year 2025 dataset, podcast advertising’s 17.6% growth ran 1.27 times the 13.9% growth of total US internet advertising and 1.73 times the 10.2% growth of digital audio as a whole. Strip podcasting out of the digital audio category and the remainder — streaming music and streaming radio — grew 7.2%, a figure Axis Intelligence Research derives by subtracting podcast revenue from the $8.4 billion audio total in each year.
2025 US Ad Revenue Growth by Format
| Format | 2025 revenue (US$ B) | YoY growth | Source |
|---|---|---|---|
| Social media | 117.7 | 32.6% | IAB / PwC, FY2025 report |
| Digital video | 78.0 | 25.4% | IAB / PwC, FY2025 report |
| Podcast | 2.862 | 17.6% | IAB / PwC, FY2025 report |
| Digital audio (total) | 8.4 | 10.2% | IAB / PwC, FY2025 report |
| Search | 114.2 | 11.0% | IAB / PwC, FY2025 report |
| Display | 81.6 | 9.8% | IAB / PwC, FY2025 report |
| Streaming music and radio (podcast excluded) | 5.538 | 7.2% | Axis Intelligence Research calculation from IAB / PwC data |
| Music, radio and podcast (cross-media) | — | 1.3% | PwC Entertainment and Media Outlook, via IAB report |
| TV advertising | — | −13.4% | PwC Entertainment and Media Outlook, via IAB report |
The last two rows are where the strategic argument lives. PwC’s cross-media view of music, radio and podcast — which folds broadcast into the same bucket — grew 1.3% while television fell 13.4%. Podcasting is the growth engine strapped to a segment that is otherwise flat, and it is being priced against a video market growing 25.4%. When a media buyer builds a 2027 audio plan, that video comparison sets the opportunity cost of every podcast dollar.
What Is the PARI™ Index and What Does It Measure?
PARI™ — the Podcast Ad Revenue Intensity Index — is a proprietary composite built by Axis Intelligence Research to answer one question that raw revenue cannot: how hard is this category working per unit of audience and per unit of ad-market opportunity?
Revenue tells you the category grew. PARI tells you whether it is converting its audience and its share position into dollars at a rate that justifies the attention it gets.
Baseline reading: 63.2 / 100, as of August 10, 2026. This is the inaugural computation and functions as the reference point for future readings; no earlier history has been computed.
PARI™ Components and Weights
| Component | Weight | Input value | Normalization ceiling | Score |
|---|---|---|---|---|
| Monetization depth — ad revenue per monthly listener | 35% | $17.14 | $25.00 | 68.6 |
| Growth premium — podcast growth ÷ internet ad growth | 25% | 1.266× | 2.00× | 63.3 |
| Category share — podcast ÷ digital audio revenue | 20% | 34.07% | 50.0% | 68.1 |
| Market penetration — podcast ÷ total internet ad revenue | 20% | 0.972% | 2.00% | 48.6 |
| PARI™ composite | 100% | — | — | 63.2 |
Formula. Each component is scored as min(input ÷ ceiling, 1) × 100, then combined as:
PARI = 0.35 × 68.6 + 0.25 × 63.3 + 0.20 × 68.1 + 0.20 × 48.6 = 63.2
Inputs and their origins. Ad revenue per monthly listener divides IAB/PwC’s FY2025 podcast revenue of $2,862.2 million by the 167 million monthly podcast consumers Edison Research at SSRS measured in The Infinite Dial 2026, a national survey of 2,050 Americans age 12+ fielded in January 2026 — the month immediately following the revenue period, which is why the two align. Growth premium, category share and market penetration all come from the IAB/PwC FY2025 report.
Ceilings and why they sit where they do. The $25.00 monetization ceiling is set at the midpoint of the published baked-in host-read CPM range, on the logic that a category monetizing every monthly listener at roughly one premium thousand-impression unit per year would be operating at full intensity. The 2.00× growth ceiling represents a category growing at double the pace of the market it sits inside. The 50% category ceiling would mean podcasting had become the majority of digital audio revenue. The 2.00% penetration ceiling is roughly double podcasting’s present share of internet advertising. These are stated so any reader can recompute the index or substitute their own ceilings.
Reading it. 63.2 describes a category monetizing well against its own audience but still small against the ad market it competes in. The weakest component by a wide margin is market penetration at 48.6 — podcasting takes under a cent of every dollar of US internet advertising. The strongest is monetization depth at 68.6. That gap is the whole investment thesis and the whole risk: podcasting has proven it can charge premium rates; it has not yet proven it can command a materially larger share of the total budget.
What would move it. A reading above 70 requires either revenue per monthly listener clearing roughly $20, or podcast share of internet advertising passing 1.3%. A reading below 58 would most likely come from audience growth outpacing revenue growth — more listeners, same dollars, thinner yield per head.
What PARI does not capture. Video podcast advertising sold through video ad markets rather than audio ones, branded-content and licensing revenue, and non-US markets all sit outside the index, because the underlying revenue figure sits outside them too.

How Much Does Podcast Advertising Cost in 2026?
Published CPMs are scarce in this market, and the ones that exist come from marketplaces disclosing their own transaction pricing. Libsyn Ads maintains the most complete public rate card, broken out by ad unit and by genre, retrieved and verified on August 10, 2026.
Podcast CPM Rates by Ad Unit, 2026
| Ad unit | CPM range | Delivery | Discount vs host-read | Source |
|---|---|---|---|---|
| Baked-in host-read (60s) | $24–26 | Permanent in episode | — | Libsyn Ads rate card |
| Baked-in host-read (30s) | $18–22 | Permanent in episode | — | Libsyn Ads rate card |
| Dynamic episodic | $18–22 | Inserted into new episodes | 20.0% | Libsyn Ads rate card |
| Dynamic full / back catalog | $14–16 | Inserted across catalog | 40.0% | Libsyn Ads rate card |
| Programmatic | $12–15 | Auction-delivered, targeted | 46.0% | Libsyn Ads rate card |
Discount percentages are calculated by Axis Intelligence Research from range midpoints ($25.00 host-read, $20.00 dynamic episodic, $15.00 back catalog, $13.50 programmatic).
The number nobody publishes: the host-read premium is 85.2%. Buying a host-read baked-in spot costs 85.2% more per thousand than buying programmatic inventory on the same platform ($25.00 ÷ $13.50 − 1). That is the price of the host’s voice and the permanence of the placement, quantified from a public rate card rather than asserted.
It is also the reason the programmatic growth story cuts both ways for publishers. IAB reported programmatic advertising revenue across all US digital formats reached $162.4 billion in 2025, up 20.5%. Every podcast impression that migrates from a host read to an auction trades a $25.00 unit for a $13.50 one. Volume has to nearly double to hold revenue flat.
Alex Rivera: Sell-through is the hidden variable in that trade. A show with 40% host-read sell-through and a full programmatic backfill can out-earn a show with 90% host-read sell-through and no backfill, because the empty slots in the first show are still generating something. The rate card comparison is real, but it prices inventory, not yield — and yield is what a publisher actually banks.
Podcast CPM Rates by Genre, 2026
Baked-in host-read placements, from the same published card.
| Genre | CPM | Index vs. genre mean | Source |
|---|---|---|---|
| Business | $30 | 122 | Libsyn Ads rate card |
| Health & Fitness | $27 | 110 | Libsyn Ads rate card |
| Technology | $26 | 106 | Libsyn Ads rate card |
| Education | $26 | 106 | Libsyn Ads rate card |
| Fiction | $24 | 98 | Libsyn Ads rate card |
| Science | $23 | 94 | Libsyn Ads rate card |
| Comedy | $23 | 94 | Libsyn Ads rate card |
| Society & Culture | $23 | 94 | Libsyn Ads rate card |
| Games | $22 | 89 | Libsyn Ads rate card |
| Leisure | $22 | 89 | Libsyn Ads rate card |
The genre mean is $24.60, computed by Axis Intelligence Research as the unweighted average of the ten published rates. Business commands a 36.4% premium over the floor genres.
The spread is narrower than most buying guides suggest — eight dollars separates the top genre from the bottom, on a card where the average is $24.60. Genre selection moves a campaign’s cost far less than format selection does. A buyer choosing Business over Games pays 36% more; a buyer choosing host-read over programmatic pays 85% more.
Worked example. A show delivering 50,000 downloads per episode, running one 60-second host-read at the $25.00 midpoint: 50,000 ÷ 1,000 × $25.00 = $1,250 per placement. The same reach bought programmatically at $13.50: $675.
Which Companies Are Capturing Podcast Ad Dollars?
Two publicly traded publishers disclose podcast revenue with enough granularity to track, and both filed in the last six weeks.
iHeartMedia reported podcast revenue of $162.1 million for Q2 2026, up 20.7% year over year, in results released on August 10, 2026. That followed $147.2 million in Q1 2026, up 26.9%. The Digital Audio Group segment posted a 33.8% adjusted EBITDA margin and, per the company, has now out-earned the broadcast Multiplatform Group on segment EBITDA for six consecutive quarters.
Axis Intelligence Research finds iHeartMedia alone booked $309.3 million of podcast revenue in the first half of 2026 — equal to 10.8% of the entire US podcast advertising market’s full-year 2025 revenue. The periods are not identical and the comparison is deliberately conservative: it measures six months of one publisher against twelve months of the whole market. At a straight annualized run rate, the same publisher would represent roughly 21.6% of the 2025 market total.
SiriusXM reported Pandora and Off-Platform advertising revenue of $413 million in Q2 2026, up 5%, in its second-quarter 2026 earnings release filed with the SEC, attributing the gain to strength in podcasting, programmatic demand and technology fees. The same filing discloses that segment cost of services rose 3%, primarily reflecting higher podcast revenue sharing — a direct read on how much of podcast revenue flows back to creators.
Disclosed Podcast and Audio Advertising Revenue, Q2 2026
| Company | Metric | Q2 2026 | YoY | Source |
|---|---|---|---|---|
| iHeartMedia | Podcast revenue | $162.1M | +20.7% | iHeartMedia Q2 2026 earnings release |
| iHeartMedia | Digital Audio Group revenue | $364.1M | +12.4% | iHeartMedia Q2 2026 earnings release |
| SiriusXM | Pandora & Off-Platform ad revenue | $413M | +5.0% | SEC filing, SiriusXM Q2 2026 earnings release |
| SiriusXM | Total company ad revenue | $454M | +5.1% | SEC filing, SiriusXM Q2 2026 earnings release |
The Listener-Hour Yield Gap
SiriusXM’s filing discloses something the podcast industry almost never publishes: advertising revenue per thousand ad-supported listener hours of $87.67 for Q2 2026, across 2.35 billion listener hours.
Set that against podcast CPMs of $24–26 per thousand downloads and the temptation is to declare streaming audio three times more valuable per unit. Axis Intelligence Research declines to merge the two figures, because they measure different things: an RPM counts every ad delivered across an hour of listening, while a podcast CPM prices a single spot in a single episode. An hour of podcast listening carrying three ad slots is not comparable to an hour of streaming radio carrying substantially more.
What the disclosed numbers do support is a composition estimate. Axis Intelligence Research estimates that on-platform Pandora inventory accounts for roughly $206 million of the segment’s $413 million in Q2 2026 advertising revenue (2.35 billion hours ÷ 1,000 × $87.67), implying the remaining 50.1% comes from off-platform sales — the bucket that contains podcast advertising. This is an estimate derived from two disclosed figures, not a company-reported split.
Who Is the Podcast Advertising Audience in 2026?
The audience case is stronger than the revenue case, which is precisely why the PARI penetration score is the weak component.
Edison Research at SSRS reports that 167 million Americans age 12+ (58%) consumed a podcast in the last month and 130 million (45%) in the last week — both all-time highs in a survey series running since 1998. Total ever-reach hit 230 million people, or 80%.
The number that should reset media plans: 68% of 35-to-54-year-olds consumed a podcast in the last month, a higher rate than the 12-to-34 cohort. Podcasting’s demographic centre of gravity has moved into the highest-income, highest-purchase-authority bracket in consumer marketing, and pricing has not fully caught up.
| Audience metric | Value | As of | Source |
|---|---|---|---|
| Monthly podcast consumers, age 12+ | 167M (58%) | Jan 2026 | Edison Research at SSRS, Infinite Dial 2026 |
| Weekly podcast consumers, age 12+ | 130M (45%) | Jan 2026 | Edison Research at SSRS, Infinite Dial 2026 |
| Ever consumed a podcast, age 12+ | 230M (80%) | Jan 2026 | Edison Research at SSRS, Infinite Dial 2026 |
| Monthly consumption, age 35–54 | 68% | Jan 2026 | Edison Research at SSRS, Infinite Dial 2026 |
| Both listened to and watched a podcast | 57% | Jan 2026 | Edison Research at SSRS, Infinite Dial 2026 |
Axis Intelligence Research finds the US market monetizes each monthly podcast listener at $17.14 per year, or $22.02 per weekly listener — approximately 33 cents per monthly listener per week. For a medium that commands 45% weekly reach of the US population age 12+, that is a strikingly low per-head figure next to the CPMs the same medium charges.

How Is Video Changing Podcast Ad Measurement?
The definitional problem is now large enough that IAB flagged it inside its own report.
The FY2025 report states plainly that its podcast figure reflects the traditional audio-based definition, and that this definition is expanding as video becomes the leading channel for podcast consumption. The report cites Sounds Profitable research finding roughly 71% of US podcast creators now produce video versions of their shows. Edison’s parallel finding — 57% of Americans have both listened to and watched a podcast — says the same thing from the demand side.
The consequence is straightforward: a growing share of podcast advertising is being transacted in video ad markets, counted in the $78.0 billion digital video line rather than the $2.862 billion podcast line. Distribution deals accelerate this. On August 10, 2026, iHeartMedia announced a video podcast agreement placing six of its titles on Disney+ and Hulu.
That means the $2.862 billion figure is best read as audio-defined podcast advertising revenue, not total revenue attributable to podcast content. Axis Intelligence Research does not publish an adjusted total, because no primary source currently measures the video-sold portion in a way that could be added without double-counting the video line. Anyone quoting a larger market size should be asked which definition produced it.
Alex Rivera: The measurement fight is going to be settled by whoever controls the ad server, not by whoever writes the definition. If a show’s video inventory clears through a video DSP with video pricing and video attribution, it is video advertising in every operational sense, and the audio category quietly loses revenue it helped create.
What Rules Govern Podcast Ad Disclosure?
Host-read advertising is endorsement advertising, and that places it squarely inside federal rules that many creators treat as optional.
The Federal Trade Commission’s guidance on endorsements, influencers and reviews requires disclosure of material connections between advertisers and endorsers. The underlying Guides, codified at 16 CFR Part 255 and revised in 2023, establish that advertisers can be liable for unsubstantiated claims made through endorsements, that endorsers themselves may be liable, and that an endorser must have been a bona fide user of a product when the endorsement represents that they were.
For a category where the entire price premium — that 85.2% — rests on the credibility of a host’s recommendation, disclosure compliance is not a legal footnote. It is the maintenance cost of the asset being sold.
Methodology
Collection. Every figure in this report was retrieved from a primary source document during the production session on August 10, 2026, and logged with its URL and retrieval date in the accompanying CSV. Revenue and format data come from the IAB/PwC Internet Advertising Revenue Report, Full-Year 2025 (published April 2026). Audience data comes from The Infinite Dial 2026 from Edison Research at SSRS, fielded January 2026 among 2,050 US respondents age 12+. Pricing data comes from the Libsyn Ads published rate card, retrieved August 10, 2026. Company revenue comes from iHeartMedia’s and SiriusXM’s own quarterly earnings releases, the latter as filed with the SEC. No aggregator, no secondary summary, and no figure from model memory appears in this report.
Calculations. All Axis Intelligence Research figures were computed in Python and cross-checked before drafting. Year-over-year growth rates derived from the IAB revenue series were validated against IAB’s own published growth labels and reproduce them to the nearest percentage point, which confirms the series was transcribed correctly. Compound growth uses (end ÷ start)^(1/years) − 1. Format discount percentages use published range midpoints. Per-listener yields divide FY2025 revenue by the January 2026 audience measurement, a one-month offset stated here because the two sources have different cadences.
PARI™ formula. PARI = 0.35·S₁ + 0.25·S₂ + 0.20·S₃ + 0.20·S₄, where each Sₙ = min(inputₙ ÷ ceilingₙ, 1) × 100. Components, inputs and ceilings are tabulated in full above. Methodology version 2026.1. Any change to components or weights will be versioned and disclosed, and prior readings will not be silently restated.
Scope. Figures are United States revenue unless otherwise noted. The IAB/PwC podcast figure uses the traditional audio-based definition; video-sold podcast inventory is largely captured in the digital video line instead. Published CPM ranges reflect one marketplace’s transaction pricing and set a market floor — direct and premium deals are negotiated above the card. The Infinite Dial is survey-based and carries the sampling characteristics of a 2,050-respondent national survey. Company revenue reflects reporting periods that differ from the annual market data, and every cross-period comparison in this report says so where it occurs.
Disagreement noted. Market sizes materially above $2.9 billion circulate for US podcast advertising in 2025. Those figures generally apply a broader definition that includes video-distributed and branded-content revenue. Axis Intelligence Research uses the IAB/PwC audio-defined figure because its methodology is published and its inputs are collected directly from sellers, and states the definitional boundary rather than blending incompatible totals.

Frequently Asked Questions
Why do published podcast market sizes differ by more than a billion dollars?
Because they count different things. The IAB/PwC figure of $2,862.2 million uses the traditional audio-based definition of a podcast. Broader estimates fold in video-distributed podcast inventory, branded content and production deals. With roughly 71% of US creators now producing video versions of their shows, the gap between definitions widens every year. Always ask which definition a number came from before comparing it to another.
Is a host-read ad worth 85% more than a programmatic one?
That is the market price, not a verdict on effectiveness. Libsyn Ads’ published card puts baked-in host-read at a $25.00 midpoint against $13.50 programmatic. What the buyer gets for the premium is the host’s endorsement, permanence in the episode, and delivery to that show’s specific audience. What they give up is geographic and behavioural targeting, which only the auction-delivered formats offer. A campaign needing zip-code precision cannot buy it at any host-read price.
Does a bigger show automatically mean a better CPM?
No — CPM is the rate per thousand, so a larger show costs more in absolute dollars at the same rate. Reach and rate are separate negotiations. On the published card, the rate moves with format and genre, and the eight-dollar spread between the highest and lowest genre is smaller than the eleven-and-a-half-dollar spread between host-read and programmatic. Format choice, not show size, is the dominant cost lever.
Why is podcast ad revenue per listener only $17 a year when CPMs are $25?
Because a CPM prices one impression against one thousand downloads, while the per-listener figure spreads a year of total category revenue across every person who listened at least once in a month. At $17.14 per monthly listener per year — about 33 cents a week — the average listener encounters far fewer sold impressions than the reach numbers imply. Unsold inventory, back-catalog listening that carries older ads, and the long tail of shows with no ad sales operation all sit inside that gap.
What happens to publisher revenue as buying shifts to programmatic?
Volume has to grow faster than price falls. Every impression moving from a $25.00 host read to a $13.50 auction requires nearly double the impressions to hold revenue flat. Programmatic advertising across all US digital formats grew 20.5% in 2025 to $162.4 billion, so the buy-side pull is real. Publishers holding margin through the transition are the ones using auction demand to fill inventory that was previously going unsold, rather than converting inventory that was already selling at card rate.
Do podcast hosts have to disclose that an ad is paid?
Yes. Host-read advertising is endorsement advertising under the FTC’s Endorsement Guides at 16 CFR Part 255, which require clear disclosure of material connections between advertiser and endorser. The 2023 revisions also confirm that endorsers themselves — not only advertisers — can face liability for statements made in an endorsement, and that a claim of personal use must be genuine.
Is podcast advertising still growing, or has it peaked?
Growing, with the percentage rate flattening and the dollar increases near record levels. The 17.6% gain in 2025 was smaller in percentage terms than 2024’s 26.4%, but added $429.1 million against a base 27 times larger than 2015. Trailing compound growth has moved from 39.1% over ten years to 16.2% over the last three — the profile of a category maturing rather than stalling.
What would signal that the category is genuinely stalling?
A PARI reading falling toward the high 50s while audience metrics keep rising. That combination means listeners are being added faster than dollars, which is the specific failure mode podcasting has flirted with before — most visibly in 2023, when revenue growth fell to 5.5% while consumption kept climbing.
Which genres actually command premium podcast ad rates?
Business leads the published card at $30, followed by Health & Fitness at $27, then Technology and Education at $26 each. Games and Leisure sit at the floor at $22. The unweighted mean across the ten published genres is $24.60. The premium tracks advertiser purchasing power rather than audience size — business and technology audiences convert into high-value B2B and financial-services buyers.

Work backwards from the placement arithmetic: reach ÷ 1,000 × CPM. A 50,000-download show at a $25.00 host-read midpoint costs $1,250 per placement; the same reach programmatically costs about $675. Most brands testing the channel run a blended plan — host-reads on a small number of shows for credibility, programmatic or back-catalog inventory for volume at a 40–46% lower rate.
