The alignment of interests between stablecoin issuers and exchanges is upgrading from “listing cooperation” to deep ties at the equity level.

According to documents Circle filed with the U.S. SEC on Tuesday, Circle issued 1.24 million shares of Class A common stock to Binance at a price of $80.84 per share, corresponding to approximately $100 million in consideration. The private placement was settled on September 17. The filing said the issue price represented a discount versus Circle’s market value prior to the announcement of the transaction.

Completed in tandem with the equity transaction is the expansion of the parties’ USDC cooperation: Circle will pay Binance a monthly incentive fee based on a certain percentage of the USDC custody volume in Circle’s modular smart contract wallet services; in return, Binance will conduct promotional activities for USDC over the next five years. This means that the depth of USDC’s penetration within the Binance ecosystem will directly affect Circle’s future fee expenditures, and Binance has moved from being a “partner” to becoming a shareholder in Circle.

Deal structure: equity issued at a discount, with a two-year lock-up period

Per the terms disclosed in the SEC filing, the 1.24 million shares Binance received are Circle Class A common stock, priced at $80.84 per share, for a total consideration of approximately $100 million. Judging by Circle’s recent share price range on the NYSE (fluctuating over the past several weeks between the $70s and just above $103), the issuance price of $80.84 sits in the lower-middle of the range, and the filing also clearly states that this price reflects a discount versus Circle’s market value prior to the transaction.

In terms of liquidity, Binance faces stricter constraints than typical strategic investors: over the maximum two-year period, Binance may not sell, transfer, or hedge these shares, except for a few limited exceptions; however, Binance retains the related voting rights. This arrangement of “having voting rights but no right to dispose” both locks in the long-term interests of both parties and also prevents Circle’s share price from coming under pressure due to strategic shareholders selling down.

Notably, this is not Circle’s first time trading equity for channel access. The core revenue for stablecoin issuers comes from interest on reserve assets, and the most direct lever to expand USDC circulation is the exchange listing, trading pairs, and wealth-management product entry points. Exchanging equity for an exchange’s promotional resources effectively converts channel fees that might otherwise be paid once upfront into long-term revenue sharing tied to the existing USDC supply.

From a strategic partnership in 2024 to today’s equity swap

The relationship between Binance and Circle did not begin today. On December 11, 2024, the two announced a strategic partnership at the Abu Dhabi Finance Week. The disclosed details at the time included: Binance would provide USDC more broadly across its global product matrix, covering trading, savings, and payments applications, serving more than 240 million global users it had publicized then; Binance would also incorporate USDC into its own corporate treasury allocation.

This deal takes the cooperation one step deeper. Under the latest arrangement, the monthly incentive fee Circle pays to Binance is linked to the amount of USDC held through Circle’s modular smart contract wallet service. This kind of “modular wallet” infrastructure is typically designed to provide on-chain accounts and custody capabilities for exchanges, wallet providers, and payment companies, with fees accrued based on the custody scale. In other words, the more Binance drives users to hold USDC through this service, the higher the monthly fees Circle pays—both sides’ interests are directly tied to growth in USDC circulation.

The protocol term is five years. For Circle, this is equivalent to using a controllable equity cost to lock in the largest exchange’s promotional resources for the next five years. For Binance, in addition to potential equity appreciation returns, it also gains a stable cash flow linked to the scale of USDC.

USDC’s competitive position: second place, but the gap remains

This deal happens at a time that is favorable to Circle, but also full of pressure.

USDC is still the world’s second-largest stablecoin. According to CoinGecko’s figures, USDC’s market cap is about $74.4 billion; while Tether’s USDT market cap is about $183 billion—USDC’s size remains less than half of USDT’s. In a compliance-focused market, USDC’s advantage is even more apparent: it has already received authorization under the EU’s MiCA framework, while USDT has not obtained the corresponding status, leading some European exchanges to remove USDT trading pairs for users in the European Economic Area. Research data shows that the share of USDC on regulated exchanges has therefore risen by roughly 5 percentage points.

However, compliance advantages do not automatically translate into circulation. USDT still dominates in offshore exchanges, on the Tron network for remittances, and in retail trading scenarios, with the number and depth of on-chain trading pairs generally higher than those of USDC. For Circle, narrowing the gap with USDT depends not on the issuance side, but on the channel side—who controls the exchange’s default trading pairs, wealth-management entry points, and fiat on/off-ramp channels can determine which stablecoin users actually use. This is precisely the value of Binance’s five-year promotional agreement.

Industry implication: Stablecoin competition shifts from the issuance end to the channel end

The signal released by this deal is more notable than the transaction amount itself.

Over the past few years, competitive focus for stablecoin issuers has centered on reserve transparency, audit attestations, the on-chain issuance scope, and regulatory licenses. These are all important, but once several leading issuers meet compliance and transparency requirements, the real incremental gains come from channels. Exchanges control the most direct retail and institutional traffic, and stablecoins’ “network effects” are precisely reflected in trading pair depth and payment scenarios: where users trade, they will naturally hold which stablecoin.

Circle chose to buy promotional resources with equity rather than cash prepayment, which also reflects restraint on the issuer’s use of capital. Circle’s net profit in 2024 was $156 million; against a backdrop where interest rates may move lower, the growth in reserve interest income carries uncertainty. Tying promotional costs to the actual amount of USDC held in custody effectively turns fixed marketing spending into a variable cost, reducing financial risk if promotional performance falls short of expectations.

For Binance, holding Circle equity carries another layer of meaning: in an environment where stablecoin regulation is increasingly becoming a policy focus, building a capital link with a leading compliant issuer can help the exchange mitigate potential compliance and liquidity risks.

What to watch next

There are three variables worth watching next: first, the specific details disclosed in the SEC filing regarding the discount magnitude and any exceptions to the lock-up period; second, the real changes in the number of trading pairs for USDC on Binance, its wealth-management products, and fiat on/off-ramp channels; and third, the adoption scale of Circle’s modular smart contract wallet service, which will directly determine how much incentive fee Binance can receive each month.

What can be certain is that in the next phase of the stablecoin war, the deciding factor is no longer how many Tokens are issued, but who can put those Tokens into the wallets and trading accounts of the most users.
