Binance has bought $100 million of Circle stock and signed a five-year deal to promote the USDC stablecoin on its platform, replacing the pair’s earlier commercial agreements and giving the exchange an equity stake in its main stablecoin partner.
Circle issued Binance 1.24 million Class A shares at $80.84 each in a private placement that closed September 17, according to CoinDesk. The price reflected a discount to Circle’s market value before the sale. Binance generally cannot sell, transfer or hedge the shares for up to two years, though it keeps voting rights over the period.
How the deal works
Under the expanded partnership, Circle will pay Binance monthly incentives tied to how much USDC is held through the exchange’s wallet infrastructure. In return, Binance promotes the stablecoin to its user base, which remains one of the largest in the industry. The structure echoes earlier arrangements but runs longer and ties payments directly to custody volumes rather than trading activity.
The new arrangement replaces earlier USDC deals the two companies signed in November 2024 and August 2025. Those agreements covered custody integration and fee sharing but did not include an equity component. Either side can end the five-year partnership early if specified events occur, though neither has signaled any intention to do so.
“Our $100 million investment and five-year commitment represent long-duration conviction,” Richard Teng, Binance co-CEO, said in an email to CoinDesk. Circle’s leadership framed the deal the same way, describing Binance as the single most important distribution partner for USDC outside the United States.
Why it matters
The deal tightens the link between the world’s largest crypto exchange and the second-largest stablecoin issuer. USDC competes with Tether’s USDT, which still holds a far larger share of circulating supply, roughly $189 billion against USDC’s $76 billion by mid-2026 estimates. Distribution through Binance gives Circle a direct channel to retail traders at a moment when stablecoin issuance has become one of the most profitable businesses in the sector, since issuers collect yield on reserve assets while passing little of it to holders.
For Binance, the stake means the exchange now profits from USDC growth in two ways: through the monthly incentive payments and through its equity position. That dual interest explains why the exchange agreed to promote a rival coin to its own BUSD successor products and to Tether, which historically dominated trading pairs on the platform. Binance wound down BUSD in 2023 after regulators ordered its issuer to stop minting, leaving a gap in dollar liquidity on the exchange that USDC deals have gradually filled.
A cloud over the exchange
The deal arrives as regulators scrutinize Binance. Bloomberg reported Tuesday that federal prosecutors in Manhattan and the Justice Department are investigating whether the exchange knowingly allowed trading that violated US sanctions on Iran. Binance said it has a zero-tolerance policy for sanctions violations and cooperates with law enforcement.
The exchange pleaded guilty to banking compliance violations in 2023 and paid $4.3 billion in fines as part of that settlement. Founder Changpeng Zhao served a short prison sentence and stepped down as chief executive, with Teng taking over. A separate Senate probe opened in February examined alleged flows of $1.7 billion to Iranian entities, which Binance said it found no evidence for, and the exchange sued the Wall Street Journal over its reporting on the matter in March. Teng accused the paper at the time of inaccurate reporting about the compliance program.
The new investigation, if it produces charges, would test the 2023 settlement’s monitoring terms. Compliance failures at that scale previously forced Binance to install an independent monitor and rework its customer verification systems. The company has since hired former regulators and expanded its financial crime unit, though outside reviews have questioned whether the changes went far enough.
Circle’s broader push
For Circle, the share sale and incentive deal lock in distribution on a platform where USDC adoption has lagged despite the coin’s strength in decentralized finance. The company is also expanding institutional products. This week it launched Digital Asset-Backed Borrowing, which lets institutions deposit bitcoin, mint a wrapped position called cirBTC and borrow USDC against it on the Morpho lending protocol, with support for its Arc blockchain and Aave planned next.
Circle also won preliminary conditional approval from the US Office of the Comptroller of the Currency for a national trust bank charter, a step toward federal oversight of its AUSD stablecoin business. The OCC approval and the Binance deal both point the same direction: Circle is spending money and equity to deepen distribution while regulators move toward clearer rules for issuers.
Analysts will watch whether the Binance arrangement shows up in future guidance on distribution costs. Circle will pay Binance a monthly fee tied to USDC held through its wallet infrastructure, a cost that scales with adoption. The company reported strong reserve income in recent quarters, but distribution deals with exchanges have historically been among its largest expenses, and investors punished the stock after earlier disclosures of promotion costs.
European regulators are also watching the stablecoin market closely. The European Central Bank and EU national central banks this week asked Brussels to scrap a MiCA rule forcing issuers to park 30 to 60 percent of reserves in bank deposits, proposing instead liquidity-based requirements. Any change would affect how Circle manages the reserves behind USDC in Europe, and the coin’s European issuers would need to adjust their reserve composition if the Commission accepts the central banks’ proposal.
