Why It Matters

Analysis of 37M unique users shows only 25-35% of AppLovin-attributed e-commerce sales are truly incremental, contradicting CEO Adam Foroughi's claim of "nearly 100%" incrementality
AppLovin allegedly operates a covert "Fingerprinting 2.0" scheme that collects proprietary user IDs from major platforms like Meta, Google, TikTok, and Snap without authorization
The company creates "Persistent Identity Graphs" (PIGs) by combining cross-platform data without user consent, potentially violating multiple privacy regulations
E-commerce client churn rate of approximately 22.6% directly contradicts CEO's claim of "almost no churn"
AppLovin's business model faces existential risk if major platforms enforce their terms of service, similar to how previous enforcement actions led to 84-87% stock price collapses for companies like Zynga and Cheetah Mobile

FAQs

What is the main accusation against AppLovin in the Muddy Waters report?

Muddy Waters alleges AppLovin has built its business on unauthorized data collection practices, violating platform terms of service while significantly overstating its performance metrics. The report claims AppLovin creates "Persistent Identity Graphs" by illegally combining user identifiers from major platforms like Meta, Google, and TikTok.

What evidence does Muddy Waters present about AppLovin's incrementality claims?

The report analyzes conversion log-level data from 776 advertisers covering 37 million unique users and $300 million in revenue. This analysis suggests only 25-35% of AppLovin-attributed e-commerce sales are truly incremental, far below CEO Adam Foroughi's claim of "nearly 100%" incrementality.

According to the report, AppLovin embeds JavaScript pixels on advertiser websites that collect proprietary identifiers from platforms like Facebook, Google, Snapchat, and TikTok. This data is then combined to create detailed user profiles without consent, enabling aggressive retargeting.

What is "Fingerprinting 2.0" as described in the report?

"Fingerprinting 2.0" refers to AppLovin's alleged advanced tracking system that operates server-side to evade detection.

The report suggests AppLovin faces existential risk if major platforms enforce their terms of service against unauthorized data collection. It draws parallels to Zynga (84% stock drop) and Cheetah Mobile (87% stock drop) following similar enforcement actions. Additionally, AppLovin may face regulatory scrutiny under various privacy laws for collecting and processing user data without proper consent.
