Circle expands USDC trading reach across OKX markets

Circle and OKX have expanded their USDC partnership to increase the stablecoin’s liquidity and use across spot, margin and futures markets on the crypto exchange.

Circle said on Sept. 2 that the companies are working together to give eligible OKX users more access to USDC-denominated trading markets, extending an existing relationship between the stablecoin issuer and the exchange.

The latest collaboration covers spot trading as well as leveraged products through margin and futures markets. Circle described trusted dollar stablecoin liquidity as part of the trading infrastructure needed as digital asset markets scale.

Specific USDC trading pairs covered by the latest announcement were not disclosed. Circle did not provide a timetable for further market additions or identify the regions where every product would be available, with access subject to user eligibility.

The announcement comes alongside a new OKX and Circle incentive program designed to encourage traders to hold and use USDC on the exchange.

Circle and OKX expand USDC trading access

OKX launched its USDC Margin Growth Program with Circle on Sept. 1, offering qualifying users a monthly 100 USDC cash reward funded by Circle.

Under the program, users must opt in, hold 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 trading volume across eligible spot, futures or margin USDC pairs.

Up to 4,000 users can qualify each month on a first-come, first-served basis. OKX said qualifying rewards are settled within seven days after the end of each month.

The trading push extends a relationship between the two companies that previously focused on moving funds between traditional dollars, USDC and blockchain networks.

In July 2025, Circle and OKX introduced zero-fee USDC conversions between USDC and the U.S. dollar. The arrangement allowed users to convert USD into USDC and back at a 1:1 rate through OKX.

Circle CEO Jeremy Allaire said at the time that demand for USDC was coming from businesses and individuals adopting dollar-denominated digital money. OKX President Hong Fang described the integration as part of the exchange’s work to make access to digital assets easier.

USDC infrastructure has expanded across OKX

The companies moved their cooperation further onchain in August when Circle brought native USDC and its Cross-Chain Transfer Protocol to X Layer, the Ethereum-compatible layer 2 network developed by OKX.

As crypto.news previously reported, the Aug. 7 integration gave developers and businesses access to USDC issued natively by Circle instead of relying only on tokens bridged from another blockchain.

Circle’s CCTP lets users move USDC between supported blockchains through a burn-and-mint process instead of locking tokens into conventional bridges and issuing wrapped representations on destination networks.

At the time of the X Layer launch, native USDC was supported across 36 networks, while CCTP connected 26 blockchains. Qualified businesses could access USDC issuance and redemption on X Layer through Circle Mint.

The infrastructure can be used for transfers, settlements, lending and decentralized applications, extending the companies’ cooperation beyond OKX’s centralized exchange.

USDC access has been developing differently across OKX’s regional operations as exchanges adjust their stablecoin offerings to local rules.

In Europe, OKX opened a USDT-to-USDC conversion route in July for customers across 30 EU and European Economic Area countries. Eligible customers can deposit USDT and convert it into USDC, which is supported under the European Union’s Markets in Crypto-Assets framework.

OKX Europe operates under a MiCA license and restricts trading in USDT for European customers. USDC and Paxos-issued USDG remain supported stablecoin options on the platform.

The exchange temporarily paused USDC deposits and withdrawals through Solana in July for scheduled wallet maintenance while keeping related trading services operational. The Solana USDC suspension applied only to transfers through that network and did not amount to a platform-wide pause in USDC trading.

Circle has pushed USDC deeper into trading platforms

Circle has pursued similar arrangements with other trading and financial platforms as it expands the places where USDC can be used for collateral, settlement and trading.

In May, Circle deepened its relationship with Hyperliquid by becoming the technical deployment partner for USDC on the decentralized trading platform. USDC continued serving as a primary collateral and quote asset across Hyperliquid’s trading ecosystem, while Circle provided infrastructure for minting, redemption and cross-chain transfers.

Circle later moved approximately 4.397 billion USDC through HyperEVM to a Coinbase-linked address. Blockchain analytics firm Arkham described the USDC transfer to Coinbase as the largest USDC transaction recorded at the time.

Coinbase had become Hyperliquid’s USDC treasury deployer under its Aligned Quote Asset framework, while Circle handled technical infrastructure supporting USDC movement across networks.

Circle’s relationship with Coinbase remains another major distribution channel for the stablecoin. During its second-quarter earnings call in August, the company said its USDC collaboration agreement with Coinbase had renewed on existing terms for another three years, extending the arrangement into 2029.

USDC circulation stood at $73.3 billion at the end of the second quarter, up 19% from a year earlier. Circle reported $701 million in quarterly revenue and reserve income, while roughly 30% of circulating USDC was held on Coinbase’s platform at the end of June.

Circle said at the time that it worked with more than 150 partners that had economic incentives to integrate, distribute or support USDC across exchanges, wallets, payment applications and other financial platforms.
