UA teams fear cost less than cost without a payback curve. Through 2025–2026 the same spike recurs: global gaming CPI up about 30% YoY to a blended $0.56; North America near $1.68 (+31%); Europe steeper (~+47%). Figures come from Adjust’s Gaming App Insights Report 2026, widely relayed via FoxData and peers. The question morphs fast: can casual still cover installs with ad recovery? Can mid-core’s long IAP cash survive the first 30 days?

Who can still afford UA is not who still has budget—it is whose LTV curve still outruns the auction.

Why CPI rose together

Cost inflation is rarely “the network raised prices.” More often the same attention is bid by more creatives and more advertisers at once. 2026 writeups call it the “AI creative paradox”: top advertisers ship roughly 2,400–2,600 creative variants per quarter (~+25–30% YoY in AppsFlyer-linked retells), impressions up about a fifth, paid-install share rising—generation got cheap; auctions got denser. Global mobile-game UA spend sits near $25B (only low-single-digit growth), so money is not infinite while attention is scarcer. You make more creatives; so does everyone else. IPM may not save your CPI.

Genre mix shifts matter too. After hyper-casual pushed “low CPI, pure IAA” to the edge, hybrid-casual, mid-core, and strategy shove budgets toward higher-LTV cohorts and lift clearing prices on good inventory. Adjust puts global Android hybrid-casual CPI from about $0.54 to about $0.95—nearly double; slots, idle RPG, and strategy can sit well above the blend. The global $0.56 is diluted by cheap high-volume Android installs—Tier-1 iOS and North America feel like multiples of that number.

Casual: can buy volume, cannot buy a wrong LTV model

Casual and puzzle long recover via rewarded and interstitial ads. Benchmark tables often place casual near ~$2.50 iOS / ~$1.50 Android as a “genre average” story; mid-core near ~$4.50 / ~$3.25, strategy higher. Samples and geos swing hard: global blends and Tier-1 live prices can diverge by an order of magnitude—but the decision rule holds: casual bid ceilings are locked by ad eCPM × retention days.

If retention is still modeled on older years, D30 ad LTV may be only fractions of a dollar; once Tier-1 Android CPI sits in the expensive band, casual Android D30 ROAS near ~15% becomes a familiar sting—recovering only a slice of UA in a month. “Healthy casual” targets often put iOS D7 ROAS around 7–8% and D30 around 40–50%; Android recovers slower. Who can afford it? Teams that still tighten reward frequency, eCPM, and D1/D7 together—and that test cheap geos before lifting winners into expensive ones. Pure install-stacking hyper-casual logic runs out of oxygen first in a +30% CPI year.

Mid-core: can afford unit price, cannot afford slow payback

Mid-core and strategy CPIs run higher, yet budgets still climb—because whales and long retention can “rationalize” unit cost. The other side of the ROAS table: mid-core D7 ROAS is often lower (some compiles put iOS near low-4%, Android near ~6% as early references); the real books close at D30/D60/D90. Hybrid IAP+IAA is frequently used to show long-run returns beating IAP-only. Who can afford it: publishers with cash to survive “weeks that look deeply red,” and products with live-ops, seasons, and battle passes deep enough to monetize.

Who cannot: not always studios that “cannot buy one install,” but those that can buy installs and cannot fund the long game—UA wants weekly ROAS, product ships quarterly content, finance watches monthly cash. Pull that triangle and mid-core testing budgets die first. The market skews: higher CPI, fewer players who can read long curves keep bidding; casual becomes a creative-factory and hybrid-monetization arms race.
