Why AppLovin Stock Fell 24% in the First Half of 2026

AppLovin (APP) dropped 24% in the first half of 2026 despite posting 66% revenue growth, as investor sentiment buckled under pressure from multiple headwinds. The selloff was driven by fears of AI disruption to its business model, intensifying competition from Meta in iOS ad tracking, and a short-seller attack that fueled downward momentum.

The disconnect between performance and price is stark. AppLovin delivered robust profit margins alongside the revenue surge, yet the stock absorbed heavy selling. Management responded with stock buybacks, signaling confidence that the market has overreacted to near-term risks.

The Meta threat centers on iOS ad tracking capabilities, where the social media giant has been gaining ground. Meanwhile, broader concerns about artificial intelligence reshaping the mobile advertising landscape have weighed on AppLovin's valuation, even as the company continues to execute operationally.
