Circle USDC Revenue Split: What It Means for Arbitrage

Circle has published a breakdown of its USDC revenue for the first half of 2026. The numbers show how one of the largest stablecoins actually pays for its reach. For an arbitrage trader, that matters: who earns from USDC shapes where the coin has liquidity, and liquidity gaps are where spreads live.

What Circle disclosed

According to the company, USDC generated about $1.4 billion in revenue in H1 2026. Of that:

• $819 million went to partners and transaction costs;
• $473 million was reinvested.

In other words, a large share of the revenue flows back out to the parties that help USDC spread across the market. The stronger their incentive, the more willing they are to hold the coin, support trading pairs and keep deposit and withdrawal networks running.

Why this matters for USDC liquidity

A stablecoin lives on distribution. When a venue has a reason to push USDC, you tend to see more USDC pairs, deeper order books and smoother transfer networks. When it doesn't, USDC stays a secondary asset with thin books.

That is the core point for arbitrage. Stablecoin liquidity is uneven across exchanges. On one venue BTC/USDC may trade nearly as tight as BTC/USDT; on another the spread is noticeably wider. That unevenness creates price gaps worth tracking, and it also raises slippage risk.

Where spreads appear: USDT vs USDC

The situations worth watching:

• Same coin, different quotes. An altcoin trades against USDT on one exchange and against USDC on another. In dollar terms the prices drift apart, especially during sharp moves when market makers lag in aligning both pairs.
• The USDT/USDC rate across exchanges. Swapping one stablecoin for the other costs different amounts on different venues. A tiny deviation can cover fees on a large ticket.
• Thin USDC pairs. Where a USDC pair is weak, orders are sparse and the price can trail the main USDT pair.

Always count the full loop: the USDT-to-USDC conversion, trading fees, withdrawal fees and transfer time. The spread on screen rarely equals what remains after costs.

USDC chains in P2P and cross-exchange trades

USDC often works as a bridge. In P2P arbitrage, buying USDT for fiat may be cheaper on one exchange while the better exit runs through another asset. A route might look like this: buy USDT on P2P, swap to USDC on spot, transfer USDC to a second exchange and sell there.

Such a route only works if:

• the USDC withdrawal network is supported on both exchanges;
• minimum withdrawal and fees don't eat the gap;
• the order book has enough depth for your size;
• there are real P2P ads that accept your amount through banks in the same country.

The wider USDC is supported, the more of these routes become viable. Still, each one needs checking on its own merits rather than assuming USDC is available everywhere.

Risks you can't ignore

Stablecoin arbitrage feels safe, but it isn't risk-free:

• Depeg moves. Any stablecoin can briefly trade below or above a dollar, hitting a position mid-route.
• Paused deposits and withdrawals. An exchange can suspend a network and leave coins stuck.
• Slippage in thin books. A low-volume USDC pair can fill worse than expected.
• Changing terms. Partnership economics can shift, and support for pairs on specific venues may shift with them.

Keep part of your balance in both stablecoins across several venues so you don't depend on transfers, and check network status before every trade.

Bottom line

Circle's report shows that USDC's reach is largely funded by money passed on to partners. For arbitrage traders it is a reminder that stablecoin liquidity is not uniform across exchanges, and those differences are where spreads appear. Compare USDT and USDC pairs, account for every fee and network, and treat no route as guaranteed: each one carries its own risk.
