Is Polymarket launching its own 'stablecoin'? Polymarket announced that it will upgrade its exchange in 2-3 weeks and introduce a brand-new collateral token, Polymarket USD, which is pegged 1:1 to USDC and will fully replace the existing USDC.e. Strictly speaking, this isn’t an independent stablecoin—it’s more like a platform-exclusive 'wrapped version of USDC.' But the signal this move sends is significant: prediction markets are building their own financial infrastructure. Regular users won’t notice any changes as the migration will happen automatically on the front end. However, API users and developers will need to handle the migration manually. On the migration day, all order books will be cleared, and the exact timing will be announced one week in advance.
