Circle’s USDC Treasury minted 250 million USDC on Solana around October 27–28, 2026, according to a transaction flagged by Whale Alert and verified by Solscan. The issuance was worth roughly $250 million at USDC’s dollar peg.
The mint is the fifth same-sized USDC issuance on Solana this month. Earlier 250 million USDC mints occurred on October 2, 6, 16 and 23, giving October a recurring cadence rather than a one-off event.
What happened on-chain
The transaction ran through the official USDC Treasury contract, the gateway Circle uses to create and redeem USDC tokens. A mint does not necessarily mean the new tokens are immediately circulating. Freshly minted USDC can remain in reserve for future transfers or to meet demand as it appears on the network.
As a result, the 250 million figure indicates capacity being prepared on Solana. It does not by itself show that $250 million in new stablecoin supply has reached trading desks.
Peg holds steady
USDC’s market price remained stable through the issuance, trading at approximately $1. USDC is the second-largest stablecoin by market capitalization, a position that keeps its treasury activity closely watched as a gauge of on-chain dollar demand.
Why the October cadence matters
Five mints of the same size in a single month form a pattern. All five occurred on Solana rather than being spread across multiple chains. Large USDC mints have tended to align with inflows into decentralized finance, or DeFi. The October issuances come amid a broader pattern of stablecoin flows in 2026 and renewed interest in DeFi applications and trading activity on Solana this year.
What it means for traders and Solana
For market participants, the immediate takeaway is liquidity. A steady supply of USDC on Solana gives traders and DeFi protocols more dollar-pegged assets to work with.
Because minted tokens can stay in reserve, the effect on circulating supply depends on what happens next. Where the tokens move after issuance will be a more telling signal than the mint itself.
