Binance bought $100 million of Circle at $80.84 a share after a sell-off, and is already up about 17%

Binance paid $80.84 a share for 1,237,011 newly issued Circle Internet Group (CRCL) Class A shares, about $100 million, in a private placement that closed on September 17, according to an 8-K Circle filed with the SEC on Tuesday. The share sale came alongside a new five-year deal under which Circle pays Binance to promote its USDC stablecoin. CoinDesk and Cointelegraph reported the filing Tuesday morning.

The "discount" depends on which day you look at

Circle's filing says the $80.84 price reflected "a discount to the market price" before closing. Against the day of the deal, that holds up: according to Nasdaq data, Circle traded between $81.51 and $85.95 on September 17 and closed at $85.09, so Binance paid about 5% less than that close and less than any price the stock traded at that day.

Against the day before, it looks different. Circle had fallen about 7% on September 16 to close at $80.45, and Binance's price was slightly above that close, about 0.5% higher. In other words, Binance bought right after a sharp drop, not at a steep markdown to where the stock had just been trading.

The timing has worked for Binance so far. Circle closed Monday at $94.49 and was trading at $96.09 in pre-market on Tuesday at 8:51 a.m. ET, up 1.7%, per Nasdaq. At Monday's close, the stake was worth about $116.9 million, a paper gain of roughly 17%. Binance cannot cash that in yet: under the subscription agreement it cannot sell, pledge or hedge the shares until two years after closing, unless it ends the commercial deal earlier under certain conditions. It keeps its voting rights.

What it means for existing shareholders

The dilution is small. Circle reported 234,685,190 Class A and 19,190,691 Class B shares outstanding as of July 30 in its second-quarter 10-Q, so the new shares add a little under 0.5% to the combined count.

The number that matters more is the other half of the deal. Circle agreed to pay Binance a monthly fee equal to a percentage of the USDC held through Circle's Modular Smart Contract Wallet infrastructure. The filing does not disclose the percentage. The new agreement replaces earlier Binance deals from November 2024 and August 2025, and either side can end it early if certain events occur.

Distribution and transaction costs are already Circle's largest expense line. In the second quarter, Circle booked $701.3 million of total revenue and reserve income and $410.4 million of distribution and transaction costs, about 59 cents of every dollar, according to the 10-Q. Coinbase alone accounted for $324.6 million of those costs. Everything else in that line, including Binance and transaction costs, came to about $86 million.

So the question for anyone following the stock is whether Binance's promotion adds enough USDC to cover a bigger incentive payment. Circle said USDC in circulation grew 19% from a year earlier to $73.3 billion in the second quarter. Its own filing warns that payments to key distributors such as Coinbase and Binance depend on how much USDC sits on their platforms, which Circle does not control.

Why rates are part of this story

Circle says it earns a substantial majority of its revenue from interest on the reserves backing USDC, and that interest rate moves feed directly into the return on those reserves. That ties the stock to Fed policy, including the latest hike covered in our Fed story, while growth in USDC balances on partner platforms also raises what Circle owes those partners.
