Binance bought 1,237,011 Class A shares in Circle at $80.84 each, a $100 million stake disclosed in an 8-K filing with the Securities and Exchange Commission on Tuesday. The share purchase and a new five-year commercial agreement both closed on 17 September. Binance cannot sell, transfer or hedge the shares for two years unless the commercial deal is terminated under specified circumstances, though it keeps its voting rights.
The commercial side is where the money flows the other way. Under the agreement, Circle pays Binance a monthly incentive fee calculated as a percentage of the USDC held through Circle’s Modular Smart Contract Wallet infrastructure, while Binance promotes the stablecoin on its platform. The deal supersedes arrangements the two companies signed in 2024 and 2025, and both sides keep unilateral rights to walk away under certain conditions.
Distribution is the expensive part of running a stablecoin. Circle earns interest on the reserves behind USDC and then shares a large slice of it with the exchanges and wallets that persuade users to hold its token rather than a rival’s. Binance, the largest crypto venue by trading volume, has backed other dollar tokens before, so locking it in for five years is as much a defensive move as a growth one. The stake also lands a week after Circle switched on Arc, its own blockchain, where USDC is the currency used to pay fees.
The filing does not disclose the percentage Circle pays, which is the number that matters. Without it, shareholders cannot tell whether $100 million of equity is a vote of confidence in Circle or a partial prepayment on fees Binance will collect back over the life of the deal. The lock-up ends three years before the commercial agreement does.
