AppLovin's Relief Rally Meets a Fresh Legal Headache in San Diego

AppLovin shares rose 5.6% Monday after nine losing sessions, but a San Diego County lawsuit over child safety and an unresolved Unity dispute weigh on the stock.

Investors in AppLovin caught a breather on Monday, snapping a punishing nine-session losing streak. The stock climbed 5.6% to close at EUR 251.25, offering some respite after a bruising stretch. By Tuesday, however, the mood had shifted again — this time courtesy of a new lawsuit filed by San Diego County.

The timing could hardly be worse. Monday's advance came without any accompanying operational news from the company, and media reports characterized it as little more than a technical rebound from oversold territory. Trading volume was below average, reinforcing the impression that the move was mechanical rather than sentiment-driven. While peers in the ad-tech space diverged — The Trade Desk retreated, Digital Turbine edged higher — AppLovin's recovery stood alone.

San Diego Alleges Ad Tech Bypassed Child Safeguards

The lawsuit, filed Tuesday, accuses AppLovin's advertising technology of circumventing child safety protections and serving ads for e-cigarettes, alcohol, dating services, and explicit content within games aimed at minors. The county is using the case to spotlight its newly established consumer protection unit.

For a company whose revenue depends on advertiser trust, the allegations carry weight beyond potential financial penalties. Advertisers tend to be highly sensitive to reputational risk, and a toxic association with underage audiences could prompt partners to reconsider their spending. Regulatory scrutiny in the digital advertising space has a way of escalating quickly, and this case places AppLovin squarely in the crosshairs.

Unity Dispute Remains Unresolved

The San Diego complaint lands on top of an already strained legal landscape. Last Friday, a California court rejected AppLovin's request for a preliminary injunction against rival Unity Software. The underlying claims between the two parties remain unresolved and continue to be litigated.

At issue is data collected through Unity's Ad Quality SDK. AppLovin alleged that Unity improperly gathered information tied to AppLovin-served ads, including creative, user, and device details as well as interaction and revenue data. Analysts at Wedbush flagged potential competitive implications, particularly for AppLovin's MAX platform. The court's refusal to grant emergency relief means the dispute will grind on, consuming management attention and keeping uncertainty alive.

A Stock Under Pressure

Friday also brought a fresh 52-week low of EUR 236.15, underscoring just how far the shares have fallen. Since the start of the year, AppLovin has shed 57% of its value. Monday's jump, while welcome, looks like a purely mechanical bounce against that backdrop — one that Tuesday's legal development may quickly snuff out.

Citi's decision to reaffirm its buy rating on Monday provided some psychological support, but it did little to alter the broader picture. The combination of an unresolved fight with Unity and a new complaint over advertising on children's devices weighs heavily on investor confidence.

What Lies Ahead

For now, the risks appear to outweigh the rewards. Until AppLovin delivers fresh operational momentum and the legal battles find resolution, intermittent share price gains are unlikely to hold. The company must defend itself on multiple fronts simultaneously — a costly endeavor that saps resources and unsettles the market. Any sustained recovery will require more than a technical rebound; it will need clarity on the legal front and a convincing growth narrative. Neither appears imminent.
