Circle just printed $3 billion worth of USDC on the Solana blockchain in a single 24-hour window.
The mint is one of the largest single-day USDC issuances on Solana to date, but it’s far from an isolated event. It fits neatly into a pattern that’s been building throughout 2026, one that tells a clear story about where institutional capital wants to park its stablecoin liquidity.
Solana’s stablecoin surge by the numbers
This $3 billion mint didn’t materialize out of thin air. Circle has been systematically ramping up USDC issuance on Solana all year, often in $250 million tranches that on-chain tracking services like Whale Alert and Lookonchain have documented in real time.
In August 2026 alone, approximately $11 billion in gross USDC mints occurred on Solana. By late August, the total USDC circulating supply on Solana crossed the $8 billion mark, representing more than 10% of the global USDC supply for the first time.
Circle minted $500 million on June 8 across two $250 million tranches. Mid-June saw a $1 billion single-day mint. On June 29, a $910 million issuance on Solana was paired with a $250 million burn on Ethereum. By mid-July, gross issuance on Solana had reached somewhere between $64 billion and $68 billion. Early September brought another $1.25 billion minted over just three days.
The institutional pipeline
BNY Mellon expanded its collaboration with Circle in June 2026 to facilitate institutional minting and custody of USDC directly on Solana. The partnership lowers friction for large institutions that want exposure to Solana’s DeFi ecosystem without navigating the technical complexity of bridging from Ethereum.
It’s worth noting that gross issuance figures don’t equal net supply growth. Redemptions and burns happen constantly, which is why the circulating supply on Solana sits at $8 billion-plus rather than the tens of billions suggested by cumulative mint totals.
What the Ethereum-to-Solana shift means
The June 29 event, where Circle minted $910 million on Solana while simultaneously burning $250 million on Ethereum, is perhaps the most telling data point of the year. Ethereum still holds the lion’s share of USDC supply, but Solana is gaining ground. Solana offers lower transaction fees and faster finality, which matters enormously when you’re settling hundreds of millions of dollars in stablecoin transactions daily.
