The USDC Treasury minted 250 million USDC, according to a transaction flagged by blockchain monitoring service Whale Alert.
Research findings put the mint on the Solana blockchain between October 27 and 28, 2026. The transaction was confirmed through Solscan as coming from the official USDC Treasury contract.
That made it the fifth time in October that Circle, USDC’s issuer, created exactly 250 million tokens in a single move.
A month of identical mints
The October pattern was strikingly consistent. Circle minted 250 million USDC on October 2, then again on October 6, October 16, and October 23.
The late-October mint closed out the run at five. Every one went through the verified USDC Treasury contract.
All of those October mints happened exclusively on Solana. The findings show no matching activity on other blockchains during the month.
The pace then sped up. On November 2, four separate 250 million USDC transactions went through, creating a total of $1 billion in new tokens.
All four landed within about 10 minutes.
Through all of this, USDC held its $1 peg. There were no reported market disruptions during the October mints.

What a mint does and doesn’t mean
According to the research, a mint does not necessarily mean circulating supply jumps right away. New tokens can sit in treasury reserves until they are needed.
The research ties this activity to liquidity dynamics across the Solana network. Decentralized finance, or DeFi, is a particular focus, since lending protocols, exchanges and trading pools all depend on a steady supply of dollar-pegged tokens.
Why Solana keeps getting the call
The research describes the issuance as aligning with wider liquidity conditions on Solana.
The identical sizing is also worth noting. Steady blocks of 250 million tokens look like routine operations rather than panicked reactions to a sudden spike.
Then came the November 2 burst. Four mints in roughly 10 minutes, totaling $1 billion, implies either a larger batch of expected demand or a decision to front-load supply.
What this means for markets and stablecoin watchers
The research offers a cautious read on the trend. Repeated large-scale minting on Solana could point to strengthening demand for dollar liquidity among institutional players, particularly in DeFi.
The peg tells a cleaner story. Large amounts of new USDC came into existence and the token stayed at $1, with no reported disruptions.
According to the research, that stability reflects investor confidence in the reserves Circle manages.
There are still things worth watching. The first is whether the minted tokens actually leave the treasury and enter circulation, since that is when issuance turns into real market liquidity.
The second is whether the Solana-only pattern holds. If Circle starts issuing similar amounts on other chains, it would suggest demand is broadening rather than concentrating.
The third is cadence. October brought five mints of 250 million USDC spread across the month, while November opened with four in roughly 10 minutes.
