Polymarket said it plans to upgrade its exchange architecture to CTF + CLOB v2 within the next two to three weeks and introduce Polymarket USD, a new token backed 1:1 by USDC. As part of the migration, the platform will move collateral from USDC.e to the new settlement asset. Polymarket also said all existing order books will be cleared on migration day, with one week’s advance notice. The update adds operational detail to Polymarket’s previously announced infrastructure overhaul, which is aimed at supporting lower-cost and more institution-friendly trading on Polygon.
