Polymarket's pUSD supply tops $500 million
Polymarket's pUSD stablecoin supply surpassed $500 million, according to data from NS3, marking a liquidity milestone for the prediction market platform. The collateral stablecoin is used to fund positions on Polymarket's event-contract markets. The Block published a chart tracking pUSD's daily supply in its decentralized-finance data section focused on prediction markets. The $500 million threshold signals rising inflows of trading capital into the CFTC-regulated venue as its World Cup and political markets draw heavier participation. The milestone comes amid intensifying rivalry with Kalshi for institutional and retail flow in regulated event contracts.
Polymarket's $32 million single-match proof point now has a parallel capital benchmark: half a billion dollars in pUSD locked on platform. That dual liquidity-and-volume track record makes the venue safer for institutional position sizes that Kalshi is simultaneously chasing with dedicated market-maker desks.
