Senator Elizabeth Warren has sent a letter to Meta CEO Mark Zuckerberg seeking full details on the company’s reported stablecoin integration plans. The letter warns that integrating a third-party stablecoin across Meta’s 3.5 billion users could raise serious risks related to competition, privacy, payment integrity, and financial stability.
Meta is currently running a small trial with a third-party stablecoin ahead of a wider launch in the second half of 2026. Senator Warren highlighted this as Meta’s second attempt after the failed Libra project in 2019. She expressed worries that Meta could use transaction data for advertising and act like a “private central bank,” potentially putting taxpayers at risk during a stablecoin run.
Warren has asked Meta to answer seven detailed questions by May 20. These include plans for the MetaPay wallet, list of stablecoins under consideration, risk management controls, profit-sharing arrangements, privacy protections, and whether Meta will ever issue its own stablecoin. She also wants to know if Meta will preference one stablecoin over other payment options.
Stablecoin adoption is rising fast, with total supply now over $303 billion. A recent survey shows 54% of crypto users held stablecoins last year. While some industry leaders believe Meta’s entry could help grow the market to $4 trillion by 2030, Senator Warren believes any move by Meta into payments must be treated with strong skepticism.
