Polymarket has launched Polymarket USD, a new stablecoin fully backed 1:1 by Circle’s USDC, alongside a comprehensive overhaul of its trading platform as it prepares for expansion into the U.S. market. This upgrade marks a strategic pivot, aiming to improve trading speed, liquidity, and give the company greater operational control, according to Zero Hedge and CryptoSlate.
The overhaul includes a complete rebuild of the trading engine, smart contracts, and order book system, designed to reduce costs and support more advanced trading activities, BeInCrypto reports. Polymarket plans to phase out USDC.e on Polygon while retaining USDC as the reserve asset backing the new stablecoin, ensuring no immediate impact on USDC’s overall market capitalization, says CryptoSlate.
This infrastructure upgrade accompanies a $600 million investment from Intercontinental Exchange, highlighting a substantial capital boost fueling the company’s growth strategy and regulatory preparation for the U.S. Bitcoin Magazine notes that the new system may also allow Polymarket to internalize governance and dispute resolution processes, improving market integrity.
The platform, valued at around $20 billion, expects the enhanced infrastructure will enable faster execution and more reliable user experiences as it targets the regulated U.S. market, as highlighted by CoinDesk. The changes could also position Polymarket to better navigate compliance requirements and expand its product offerings.
Looking ahead, industry watchers will focus on how Polymarket manages regulatory engagement in the U.S. and whether the new stablecoin and system improvements can significantly increase user adoption and liquidity. The company's upcoming operational decisions and regulatory filings will likely shape its trajectory within the expanding crypto prediction market landscape.
