Circle and Binance have signed a new five-year commercial agreement, announced Sept. 22, alongside a $100 million equity investment from the exchange. Binance bought 1.237 million Circle Class A shares at $80.84 each, a 5% discount to the Sept. 17 close, with a two-year restriction on selling, pledging, or hedging. The deal replaces the November 2024 and August 2025 arrangements and extends a partnership under which USDC held by Binance customers has grown from about $1.5 billion on Oct. 1, 2024 to roughly $7.1 billion, a 376% jump.
Why it matters
Binance has become one of USDC's most important distribution channels. Its customer balances went from less than 4% of global USDC supply to almost 10% in under two years, while total USDC in circulation grew a more modest 87% to about $74.4 billion. The surge also narrowed Tether's lead on the exchange: the USDT-to-USDC ratio among Binance customers fell from 14.3-to-1 to roughly 4.5-to-1, as USDT balances rose just 51% against USDC's 376%.
Circle CEO Jeremy Allaire framed the deal as an emerging-markets play, writing that the partnership "will accelerate global and emerging market preference and adoption of USDC" and extend access to "hundreds of millions of people and businesses."
Market impact
The growth has been expensive. The November 2024 deal carried a $60.25 million upfront fee plus monthly incentives tied to balances, and Circle's Binance-related distribution costs rose $152.1 million in 2025. In Q2, Circle generated about $668 million of reserve income against roughly $410 million of distribution and transaction costs, about 61% of the total. Clear Street analysts estimate that an additional $1 billion of USDC at a 3.5% reserve return would yield $35 million gross, of which Circle might keep only $4 million to $7 million under high-double-digit incentive terms. Neither the new fee rate nor minimum balance commitments have been disclosed. Q3 results, with reported Binance USDC holdings and non-Coinbase distribution expenses, will show what this channel actually costs.
