AI advertising

AppLovin’s stock (APP) fell sharply after a Bloomberg report revealed an SEC probe into its data collection for targeted advertising. The investigation, spurred by a whistleblower and short-seller concerns, centers on potential violations of advertising agreements. AppLovin, recently added to the S&P 500, defends its practices, but the news triggered a significant stock decline after a period of substantial growth fueled by its AI-powered AXON engine. Short-sellers have previously criticized AppLovin’s data privacy and ad targeting, alleging violations of app store terms of service.
