Stablecoin supply on Polygon is exploding...

Polygon Breaks Away From the Pack

While stablecoin supply has contracted across several major networks over the past week, @0xPolygon is moving in the opposite direction. The total stablecoin market cap on Polygon has surged more than 8% in seven days, reaching approximately $3.678 billion at time of writing. That puts $POL in eighth place globally by stablecoin supply and within reach of @arbitrum, which currently holds the seventh spot.

The divergence is notable. @Ethereum, @trondao, and @Solana have all seen their stablecoin supply edge lower over the same period, underscoring that Polygon's gains are not simply a reflection of a rising tide across the sector.

A Network Built Around Stablecoin Activity

The latest surge is part of a longer-running growth story. By February 2026, stablecoin supply on the Polygon network had already reached an all-time high of $3.4 billion, more than doubling from $1.6 billion in January 2025. That represented a near 100% year-on-year increase, outpacing the global stablecoin market average growth of 45.2%.

USDC is the dominant stablecoin on Polygon with a 51.1% market share, followed by USDT at 27.8% and USDS at 19.5%. The network's strength is not just in idle supply, either. Polygon reportedly processed 178 million USD stablecoin transactions in March 2026, reflecting high velocity rather than parked balances.

Institutional payment flows have helped drive that activity. Revolut moved $810 million through Polygon in 2025, Tazapay processed $687 million on the network in January 2026 alone, and Stripe processed over $75 million in payments on the network.

Polygon Labs is also pushing deeper into regulated payments infrastructure. The company is exploring raising up to $100 million for a new unit focused on stablecoin payments, as it looks to expand into regulated financial services and drive greater transaction volume on its network. This forms part of a broader vision called the "Open Money Stack," which was announced in January 2026 and marked the network's formal transition from an Ethereum sidechain to a full-stack payments ecosystem.

With supply now approaching $3.7 billion and a potential flip of Arbitrum for the seventh spot in sight, Polygon's position in the stablecoin rankings looks set to keep climbing.
