Mobile game IAP revenue grew just 1.3% in 2025 — to $81.75 billion. Sounds okay until you read the next line: non-gaming apps hit $85.6 billion. For the first time in history, non-gaming apps out-earned mobile games on IAP.
Downloads fell 7%. Revenue barely moved. And 92.5% of IAP revenue is concentrated in the top 1% of games. For the other 99% of publishers, the ROAS math is getting brutal.
What's Actually Breaking
The core problem isn't ad spend — global gaming UA spend hit $25B in 2025, growing 3.8% YoY. Publishers are still spending. The problem is what they're getting back.
Casual game D7 retention has been declining steadily since 2022. Players are harder to retain, faster to churn, and less likely to convert on IAP. When your D7 retention drops, your LTV model breaks — and when your LTV model breaks, your ROAS targets become fiction.
Meanwhile, ad impressions rose 20% YoY as AI-fueled creative production flooded the auction. More competition for the same shrinking pool of retained players. CPIs are rising. Returns are not keeping pace.
The Ad Monetization Side of the Story
For ad-supported publishers, the picture is more nuanced — but not necessarily better. On iOS, AppLovin commands 39% of ad revenue share in Q1 2026. On Android, Google AdMob leads at 24% but the field is far more competitive, with no network running away with it.
US iOS ad revenue share dropped from 59% in Q4 2025 to 56% in Q1 2026. The concentration is slowly spreading — Japan grew from 9% to 11% — but the US still accounts for more than half of all iOS ad monetization. If your game skews non-US, you're fighting for a fraction of the pie.
On Android, the "Others" category accounts for 32% of global ad revenue — a massive, fragmented long tail across emerging markets. The volume is real. The eCPMs are not yet catching up to engagement levels.
The Network Shift Worth Watching
Across both platforms and both halves of 2025, two networks are consistently growing: Unity Ads and Liftoff. Unity Ads led iOS growth at 4% YoY in both Q4 2025 and Q1 2026. Liftoff posted 2–3% growth across both platforms consistently. Pangle surged 7% on Android in Q4 2025 — but that momentum slowed to 2% in Q1 2026.
The publishers with the strongest ad monetization returns aren't just picking the biggest network. They're spotting these shifts early — moving budget toward networks with momentum before the rest of the market catches up.
The Concentration Problem
In Q1 2026, 5 companies generated $3.4B out of $14.1B in total IAP revenue — that's 24% of the entire market in the hands of five publishers. The top 1% captures 92.5% of IAP. Strategy and puzzle are the only genres growing meaningfully, with strategy IAP up 20% and puzzle up 14% in 2025.
For mid-tier and indie publishers not in strategy or puzzle, the IAP route is increasingly a winner-takes-all game they're not winning. The rational response is to double down on ad monetization — but that only works if your retention is strong enough to generate the session volume that makes ad revenue meaningful.
What the Smart Publishers Are Doing
The publishers navigating this environment have three things in common:
- Hybrid monetization is non-negotiable. The debate about IAA vs IAP ratio (50/50, 70/30, 80/20) is less important than having both levers. Publishers dependent on a single revenue stream are the most exposed when either metric turns.
- They're optimizing for session value, not just install volume. When D7 retention is declining, the answer isn't more installs — it's more revenue per session from the users you do retain. That means smarter rewarded video placement, tighter interstitial frequency caps, and real-time eCPM optimization by network and geography.
- They're treating UA as a portfolio, not a channel. iOS advertisers increased the number of media sources they used by up to 15% YoY. The publishers with the best ROAS aren't relying on one network or one format — they're diversifying and measuring incrementality at the source level.
The ROAS crisis in mobile gaming is real. But it's not evenly distributed. The publishers who understand their monetization stack — both the ad side and the IAP side — well enough to optimize each independently are still finding margin. The ones treating UA as a volume game are running out of runway.
