Binance invested $100 million in Circle, and also signed a five-year commercial agreement to promote USDC across all platforms.

The results are already visible: since the partnership, the number of Binance spot trading pairs for USDC has grown from 140 to 329, and monthly trading volume has doubled from $20–40 billion to more than $80 billion. Throughout 2026, it has remained the largest venue for USDC spot trading volume.

Analysts say this is long-term pressure on USDT, especially in emerging markets; but USDT’s trading-pair depth, local liquidity, and user habits are something no one can shake in the short term. USDC has a market cap of $74 billion, while USDT is $140 billion—there’s still a big gap.
