Polymarket’s native stablecoin, pUSD, has surpassed $500 million in circulating supply, climbing from $213 million on Apr 28, identified as its launch day, to $509 million today. That means the app-specific stablecoin more than doubled in less than two months, a trajectory the source characterizes as among the fastest growth rates for stablecoins in 2026. App-specific stablecoins are tokens designed primarily for use inside a single platform, where they can support trading, settlement, and on-platform liquidity.
