Mobile advertising sits inside a fast-growing digital advertising market, but its economics vary sharply by app category, revenue model, acquisition source, and user cohort. U.S. internet advertising revenue reached $294.6 billion in 2025, while a measured AppsFlyer sample recorded $7.2 billion in in-app advertising revenue from January 2025 through March 2026. The figures below separate U.S. market context from mobile-app observations, survey results, and estimates.

U.S. digital advertising market context
The IAB / PwC Internet Advertising Revenue Report: Full Year 2025 places U.S. internet advertising revenue at $294.6 billion in 2025, a 13.9% year-over-year increase. This is an internet-advertising total, not a mobile-only allocation. The report includes mobile devices, so it is useful for understanding the market surrounding mobile advertising without treating the total as revenue generated exclusively on phones or tablets. (IAB / PwC Internet Advertising Revenue Report: Full Year 2025)
The reported annual totals rose each year from 2021 through 2025:
| Year | U.S. internet advertising revenue |
|---|---|
| 2021 | $189.3 billion |
| 2022 | $209.7 billion |
| 2023 | $225.0 billion |
| 2024 | $258.6 billion |
| 2025 | $294.6 billion |
Quarterly 2025 revenue also increased through the year. Q1 reached $65.0 billion, 12.2% above Q1 2024; Q2 reached $70.0 billion, up 12.8%; Q3 reached $74.5 billion, up 14.9%; and Q4 reached $85.0 billion, up 15.4%. These quarterly figures show the measurement period and year-over-year comparisons reported by IAB / PwC rather than a mobile-only seasonal pattern.
Several major digital channels contributed to the 2025 total. Search advertising reached $114.2 billion and represented 38.8% of internet advertising revenue. Social-media advertising reached $117.7 billion, up 32.6% year over year, while programmatic advertising reached $162.4 billion, up 20.5%. Commerce-media advertising reached $63.4 billion, up 18.0%.
Video and display also remained substantial categories. Digital video advertising revenue reached $78.0 billion in 2025, up 25.4% year over year. Display advertising reached $81.6 billion, up 9.8%. The 10 largest companies captured 84.1% of U.S. internet advertising revenue in 2025, indicating that the broader market is highly concentrated even as mobile inventory is distributed across many apps and platforms.
In-app advertising growth and revenue mix
The AppsFlyer State of App Monetization—2026 Edition reports $7.2 billion of in-app advertising revenue in its dataset from January 2025 through March 2026. Its results are anonymous, aggregated observations from measured app and revenue samples; they describe the participating sample rather than every mobile app or advertiser. (The State of App Monetization - 2026 Edition)
In-app advertising revenue grew 14% year over year in Q1 2026 compared with Q1 2025. Growth was not universal: 57% of active accounts in the AppsFlyer dataset recorded year-over-year growth in in-app advertising revenue during that comparison. The result suggests expansion across a majority of observed accounts while leaving a substantial minority without year-over-year growth.
Advertising also changed position within diversified app businesses. Among apps generating meaningful advertising, purchase, and subscription revenue, advertising represented about 63% of revenue in January 2025 and about 56% by early 2026. In that same diversified-app cohort, advertising revenue’s monthly concentration peaked at 7.8% of measured-period ad earnings in December 2025. These percentages describe the observed revenue mix and concentration in the specified AppsFlyer sample, not a universal benchmark for all apps.
The distinction between advertising, purchases, and subscriptions matters when assessing a mobile advertising strategy. AppsFlyer uses IAA for in-app advertising, ARPU for average revenue per user, and IAP and IAS for in-app purchase and in-app subscription revenue. A category can have a high advertising share while still using purchases or subscriptions, and a diversified app can see advertising become a smaller share even while advertising revenue grows.
Ad monetization by app category
The AppsFlyer early-2026 observations show different 90-day in-app advertising ARPU levels per install globally:
| App category | 90-day in-app advertising ARPU per install |
|---|---|
| Casual games | $0.55 |
| Casino games | $0.47 |
| Midcore games | $0.40 |
| Hypercasual games | $0.22 |
Casual games recorded the highest listed value at $0.55 per install by Day 90, followed by casino games at $0.47, midcore games at $0.40, and hypercasual games at $0.22. These are global, category-level observations from the early-2026 sample and should not be read as guaranteed revenue per install for an individual title.
The observed monetization models differed as well. Hypercasual apps were 79% IAA-only in the sample. Casual games were split across 47% IAP-only, 28% IAA-only, and 21% hybrid models. Midcore games were 90% IAP-only, while casino games were 83% IAP. Among non-gaming apps, 15% monetized through subscriptions; the gaming categories were dominated by in-app purchases and advertising in the cited sample.
These category differences affect how advertisers interpret inventory and how app publishers evaluate revenue. An IAA-only hypercasual app may depend heavily on ad impressions and early engagement, while a midcore or casino app may rely more heavily on purchases. The percentages show the composition of the measured sample, not the share of every app in each category.
How quickly mobile ads generate revenue
Revenue timing is one of the clearest differences between mobile advertising and other app monetization models. In the early-2026 AppsFlyer cohort, in-app advertising generated 89% of its full Day 60 revenue by Day 7 after install. In-app purchases generated 60% of their full Day 60 revenue by Day 7, and in-app subscriptions generated 52%.
The first 24 hours were especially important for advertising. In-app advertising generated 57% of its full Day 60 revenue during the first day after install. Subscriptions generated 28% in the same first-24-hour period. The comparison indicates faster early revenue realization for advertising in this cohort, while the figures remain cohort observations rather than a forecast for a specific campaign.
Category timing varied. Hypercasual games generated 63% of their in-app advertising revenue on Day 1. For purchases, casino games generated 23% of their revenue on Day 1, compared with 38% across all apps. Gaming in-app subscriptions generated 21% of their revenue on Day 1, compared with 28% for the overall in-app subscription average.
Non-gaming purchase behavior also had measurable 30-day conversion rates. Non-gaming apps converted 9.84% of installs into one-time buyers within 30 days and 4.64% of installs into repeat buyers within 30 days. Those purchase rates are not advertising conversion rates, but they help distinguish ad-supported revenue from purchase-based app economics when evaluating mobile user value.
Paid acquisition and app economics
Paid and organic installs contributed different shares of downstream app revenue in the early-2026 AppsFlyer observations. Paid installs generated 59% of gaming store in-app-purchase revenue overall and 30% of non-gaming subscription revenue overall. At category level, paid installs generated 79% of hypercasual gaming in-app-purchase revenue, 64% of casino gaming in-app-purchase revenue, 61% of casual gaming in-app-purchase revenue, and 49% of midcore gaming in-app-purchase revenue.
Regional figures add another layer to the picture. In Latin America, paid installs generated 37% of casual gaming in-app-purchase revenue and 43% of midcore gaming in-app-purchase revenue; organic installs generated the remaining 57% for midcore gaming in that region. In the Middle East and Africa, organic installs generated 80% of non-gaming subscription revenue. Paid installs generated about 31% of non-gaming subscription revenue in both Latin America and North America plus Europe.
These observations connect advertising spend with monetization without proving that paid acquisition caused the revenue share. They show how much of the measured revenue was associated with paid versus organic installs in the specified categories and regions. For campaign planning, the relevant comparison is therefore not only ad revenue per install, but also whether paid users produce purchases, subscriptions, or advertising revenue over the stated measurement windows.
Mobile gaming audiences and ad performance
Unity’s 2025 survey, titled “From niche to norm: The evolution of the gamer identity,” found that 39% of people who play mobile games reported making a purchase after seeing an in-game ad. The reported share rose to 53% among Gen Z mobile-game players. In the same survey, 58% of Gen Z players said they were more likely to consider a brand that advertises in their favorite games, compared with 56% of Millennial players. (From niche to norm: The evolution of the gamer identity)
The survey also reported mobile gaming reach at 69% of the surveyed demographic comparison, versus 41% for console gaming. A separate 2025 forecast in the cited Unity material expected 57% of the U.S. population to play games across consoles, PCs, and mobile. Because these are survey results or Unity estimates, their populations, geography, and dates should be retained when using them; they should not be generalized beyond the stated sample or market.
Gaming identity was not universal among players. Only 23% of players in the cited survey identified themselves as a gamer. At the same time, 54% of Gen Z and 52% of Millennials reported paying for gaming experiences. Together, these figures describe a broad audience that may not adopt the “gamer” label while still engaging with or paying for games.
Unity’s “Bringing Transparency to Mobile Game Advertising” article reported that more than 70% of the top 1,000 mobile games were built on Unity’s engine in December 2025. Made-with-Unity games reached more than 3 billion unique monthly active devices globally, including 256 million unique monthly active devices in the U.S. (Bringing Transparency to Mobile Game Advertising) These are Unity-reported audience estimates for December 2025, not an independently measured total of all mobile-game devices.
For advertisers, the combination of the 2025 survey and Unity’s December 2025 estimates points to two distinct considerations: the potential scale of mobile-game reach and the reported likelihood of ad-influenced purchase or brand consideration among particular player groups. The cited measures should remain labeled as survey results or Unity estimates, with their geography and measurement periods intact.
