Fiserv USD (FIUSD) — Pre-Launch Stablecoin

The Payments Stack Play

Fiserv processes $2 trillion in payments annually for 6,000+ financial institutions and wants to make stablecoins just another rail in that plumbing. FIUSD is less a single stablecoin and more a platform: Paxos handles issuance, Circle provides ecosystem interop, PayPal enables interoperability, and Mastercard connects the payments network. The centralized-dependent classification captures this architecture accurately — FIUSD depends on an entire constellation of partners, any of which could become a bottleneck. The end-of-2025 launch target has quietly slipped into 2026 with no firm date, which either means careful regulatory preparation or the inherent difficulty of coordinating four major fintech companies on a shared timeline.
