MILESTONE | Polymarket Tops $10 billion Monthly Volume for First Time in March 2026

Decentralized prediction market platform, Polymarket, recorded $10.57 billion in trading volume in March 2026, marking the first time the platform has crossed the $10 billion monthly threshold, according to internal data.

The figure represents a 33% increase from February 2026 and is roughly 2.5 times higher than volumes seen during the platform's previous peak around the October 2024 U.S. election cycle underscoring growing demand for event-based trading markets.

Total trading volume for Q1 2026 reached approximately $26.2 billion, up more than 90% from the previous quarter, highlighting sustained momentum into 2026.

Growth was also evident in Polymarket US, the firm's U.S.-focused platform launched in the fourth quarter of 2025 under no-action relief from the Commodity Futures Trading Commission (CFTC). The unit generated over $700 million in March 2026 volume, a 167% increase month-on-month.

Polymarket US now accounts for 6.6% of total platform activity, more than doubling its share since the start of 2026, despite remaining invite-only and limited to sports-related markets.

The restricted scope means major categories such as geopolitics and cryptocurrency markets, key drivers of global Polymarket activity, are not yet available to U.S. users.

Analysts say expanding access to these segments could further accelerate growth particularly as regulatory clarity evolves and broader participation becomes possible.
