Circle and OKX are expanding USDC liquidity and trading access across spot, margin and futures markets, giving eligible users more ways to trade in USDC-denominated markets. OKX has also launched a USDC Margin Growth Program, funded by Circle, that offers qualifying users a monthly 100 USDC reward. Participants must opt in, maintain at least 20,000 USDC in their OKX Trading Account for 17 consecutive days during a calendar month, and record more than 1,000 USDC in single-side volume across eligible USDC spot, futures or margin pairs. The program is limited to 4,000 users monthly on a first-come, first-served basis, with rewards settled within seven days after month-end. The expanded relationship follows zero-fee USD-to-USDC conversions introduced in July 2025 and native USDC support, along with Circle’s Cross-Chain Transfer Protocol, on OKX’s X Layer, an Ethereum-compatible layer 2 network. Specific trading pairs, rollout timing and regional availability for the latest expansion were not disclosed, and access depends on user eligibility. The development reflects Circle’s broader effort to extend USDC, a dollar-pegged stablecoin, across exchanges, wallets, payment applications and other financial platforms for trading, collateral and settlement.
