Senator Elizabeth Warren Presses Mark Zuckerberg Over Meta Stablecoin Push

• Warren asked Mark Zuckerberg to explain Meta’s reported stablecoin payment testing across major platforms.

• Senator warned stablecoin integration could expand Meta’s control over payments, data, and advertising systems.

• Congress seeks clarity as Meta faces questions on AML safeguards, partner selection, and financial risks.

Senator Elizabeth Warren has demanded answers from Mark Zuckerberg over reports that Meta Platforms plans to test stablecoin payments across its platforms in coming months. In a letter sent this week, Warren warned that integrating stablecoins into Facebook, Instagram, WhatsApp, and Messenger could affect competition, privacy, and financial stability across Meta’s 3.5 billion-user network.

Warren Revives Libra Concerns

According to Warren, Meta’s earlier Libra project raised bipartisan opposition because of concerns surrounding surveillance and market control. She stated that transaction data tied to stablecoin activity could strengthen Meta’s advertising business and expand its influence across digital payments.

Warren also questioned whether Meta could favor one stablecoin over competing payment options on its platforms. Additionally, she warned that a large-scale stablecoin rollout could create broader risks if users suddenly withdrew funds during market stress.

The letter referenced reports from May 2025 claiming Meta explored stablecoin payouts with crypto firms. At the time, Meta reportedly told Warren and Senator Richard Blumenthal it had no plans to issue its own stablecoin.

However, Warren said Meta never explained its commercial relationships with third-party stablecoin providers. She also requested clarity on whether MetaPay could eventually hold stablecoin balances instead of payment credentials alone.

Meta Faces Questions on Platform Control

Warren asked Meta to disclose whether it already selected stablecoins for its reported “small and focused trial.” She also requested details about risk controls, profit-sharing agreements, and Meta’s ability to influence stablecoin operations indirectly.

Furthermore, the senator questioned how Meta plans to manage anti-money laundering controls tied to stablecoin activity. She also asked whether Meta strengthened illicit finance safeguards before beginning any integration efforts.

The letter requested a full explanation of Meta’s review process for selecting stablecoin partners. Warren specifically asked which features Meta seeks in a stablecoin and which risks it intends to avoid.

Congress Seeks More Stablecoin Clarity

Warren stated that lawmakers need transparency while Congress debates cryptocurrency legislation. She argued that Meta’s scale gives any payment integration broader importance for the U.S. financial system.

The senator also pointed to Meta’s past scrutiny over privacy practices, children’s safety, and antitrust concerns. She asked the company to respond to seven detailed questions by May 20, 2026.

Finally, Warren requested confirmation on whether Meta still rejects plans to issue its own stablecoin or private digital currency.
