• UK regulator Ofcom has opened an online safety investigation into Meta’s disappearing messaging feature on Instagram Instants under the new Online Safety Act, while Meta challenges the scope of Ofcom’s information requests and related fees in the UK High Court.
• The probe is the first enforcement action under the fully implemented Online Safety Act, which introduces strict content and safety duties for services like Instagram and could affect how Meta designs, documents and monitors private messaging tools.
• Meta shares trade around $738.88, with the stock up about 19.8% over the past 30 days, reflecting recent strong momentum despite rising legal and compliance scrutiny.

Fresh regulatory pressure in a major market puts Meta’s content and privacy decisions under closer scrutiny and may add compliance cost and operational constraints. The key investor question is how much flexibility the business retains in rolling out and modifying messaging features globally.
