What Could Derail AppLovin Stock?
AppLovin (APP) holders have been through a rough stretch. The shares lost 54% over the past year, while the S&P 500 gained 16.8%. A $10,000 holding from a year ago is now worth about $4,560. In September, law firms began announcing a securities class action over what AppLovin told investors. For you, the bigger issue is a business problem, not the legal fight. So what is the biggest risk for AppLovin stock from here?
AppLovin Stock’s Biggest Risk Is Slower Ad Model Gains
AppLovin stock is most likely to be derailed by slower progress in the company’s ad models. Management said the pace of meaningful model improvement was lighter than normal in the second quarter of 2026. Management tied that quarter’s shortfall to the slower pace.
Second-quarter revenue was $1.92 billion. Management said that was just below the midpoint of its own guidance range. By management’s account, the next step up in model performance landed just after the quarter ended.
The slowdown has also become a legal matter. A securities class action covers investors who bought AppLovin securities from February 12 to August 5, 2026. The suit alleges that the company misled investors about its AI progress. Management called the model work research and development, with no guarantee of a lift every three months. So slow stretches in its models can happen again.
How Much Of AppLovin’s Growth Depends On Its Models?
AppLovin’s revenue was $5.5 billion in fiscal 2025. That revenue grew 70% from fiscal 2024. AppLovin reports it all as one advertising business, which includes its AppLovin Ads Manager platform and MAX. Management said gaming is still the majority of its revenue. By management’s account, model performance is the single biggest driver of gaming’s growth.
Revenue growth is already slowing. Year-over-year growth fell for three straight quarters. It went from 68.2% in the third quarter of 2025 to 52.8% in the second quarter of 2026. Management’s guide for the third quarter of 2026 is growth of 46% to 48%.
Management said the slower model pace had already been addressed and the third quarter was off to a strong start. Management’s guide also leaves out any model releases that are not yet live. Those are management’s claims and forecasts, not results.
AppLovin stock already sits 58.3% below its high of the past year. It trades at 23.3 times its past year of earnings, close to the S&P 500’s 21.9. The price appears to assume that today’s fast growth will not last.
AppLovin’s operating margin, the share of revenue left after running costs, was 77.4% over the past year. That is close to its five-year high of 78.1%. With margins this close to their five-year high, they have little room to rise. Profit could fall if model gains stall again.
How Far Could AppLovin Stock Fall?
AppLovin stock has fallen much further than the S&P 500 in past market shocks. In the 2022 inflation shock, it fell 82% from peak to trough, against 24% for the index. A $10,000 holding at that peak was worth about $1,800 at the low. In the 2025 tariff shock, the stock fell 56% while the index fell 19%. Those were market-wide shocks.
Slower model gains are a real risk to take seriously, but they have not yet shown up as shrinking revenue. A second quarter of light model gains is the larger worry, since that would suggest the slowdown is lasting.
You will see whether the slowdown is lasting in AppLovin’s third-quarter revenue growth. Second-quarter revenue landed just below the middle of its guide. If third-quarter revenue does the same, that would be a second slow quarter in a row. If it lands in the upper half or above, management’s account of a material lift in the third quarter holds up. On the legal side, investors who want to lead the class action must ask the court by November 16, 2026.
For holders, the case for AppLovin depends on its models improving again without long pauses. You will learn more about that from third-quarter revenue than from the class action.
