Key Takeaways:
- Binance invested $100 million in Circle, purchasing over 1.2 million shares, as part of a new five-year agreement to promote USDC across its platform.
- USDC’s monthly trading volume on Binance has grown from $20-40 billion to over $80 billion since their original 2024 partnership.
- Despite the growth, USDC’s $75.3 billion market cap still trails USDT’s $183.8 billion, with Tether retaining strong liquidity and payment network advantages.
Circle and Binance have deepened their relationship in a big way. Binance invested $100 million into Circle and signed a new five-year agreement on September 22, giving the stablecoin issuer a stronger foothold in international markets where Tether’s USDT has long dominated.
The deal isn’t just symbolic. It ties Circle’s stablecoin growth directly to one of the largest trading platforms in the world, while giving Binance a financial stake in Circle’s success.
What’s Actually in the Deal
According to disclosures, Binance purchased just over 1.2 million Class A shares in Circle at $80.84 apiece, generating $100 million for Circle in a transaction that closed on September 17. Binance keeps voting rights tied to those shares but agreed to hold off on selling, transferring, or hedging them for up to two years, with some exceptions built in.
On the commercial side, Circle will pay Binance based on USDC balances held through its Modular Smart Contract Wallet service, while Binance commits to actively promoting USDC across its platform. The new agreement replaces earlier partnerships from November 2024 and August 2025 — meaning this isn’t a fresh start so much as a deeper version of a relationship that already existed.
Clear Street analyst Owen Lau described the arrangement as bringing Binance and Circle closer together, drawing a comparison to Circle’s existing shareholder-distributor relationship with Coinbase. Binance co-CEO Richard Teng framed the investment as a sign of long-term confidence in Circle, while Circle CEO Jeremy Allaire pointed to Binance’s role in expanding dollar stablecoin distribution globally.

USDC’s Momentum on Binance Is Already Visible
This isn’t a partnership starting from scratch. Binance and Circle first began working together in December 2024, when Binance offered around 140 USDC-quoted spot markets. Since then, the results have been notable: Kaiko’s head of research, Anastasia Melachrinos, said Binance has consistently captured the largest share of USDC spot trading in 2026, with daily volume in the $5 billion to $10 billion range — roughly 10 to 20 times what many competing exchanges see.
Monthly USDC trading volume on Binance has climbed from an estimated $20-40 billion before the original partnership to more than $80 billion recently. That said, Binance regularly drops trading pairs that don’t meet its liquidity thresholds, so growth in distribution doesn’t guarantee every market stays available long-term.
Tether Still Holds a Commanding Lead
Despite the momentum, USDC remains well behind USDT in overall market size. As of late September, USDC’s market cap sat around $75.3 billion, compared to USDT’s roughly $183.8 billion. Gravity Team CEO Martins Benkitis said the Binance partnership gives Circle a real path to expand USDC adoption, particularly in trading and emerging markets, but noted that Tether’s established liquidity and existing user relationships remain a strong advantage that won’t disappear overnight.
Circle isn’t relying on Binance alone to close that gap. The company is also expanding into payments infrastructure, recently announcing a $400 million acquisition of Singapore-based Tazapay to gain banking relationships across more than 100 markets, and launching the mainnet for its Arc blockchain with backing from institutional heavyweights including Visa, BlackRock, and Mastercard.
Whether the Binance deal meaningfully shifts the balance between USDC and USDT will likely take time to show up in the numbers. But it gives Circle a clearer, more committed channel into markets where Tether has historically had the advantage.
