Circle's USDC Treasury mints 250 million USDC on Solana, fifth such mint in October
In brief
- Circle's USDC Treasury minted 250 million USDC on Solana between October 27 and 28, 2026.
- The mint was the fifth of exactly 250 million USDC in October.
- Earlier mints came on October 2, 6, 16 and 23, all on Solana.
- USDC held its $1 peg throughout, according to Crypto Briefing.
- Minted USDC can stay in the treasury, so a mint isn't automatically new circulating supply.
Five identical tranches on one chain
The latest issuance follows earlier 250 million USDC mints on October 2, 6, 16 and 23, Crypto Briefing reported. On-chain tracker Whale Alert flagged the newest one shortly after it went through, and it confirmed the mints as legitimate.
Each transaction traced back to the official USDC Treasury contract on Solana (block explorer Solscan verified that link), per the report. Circle didn't do one big issuance. It spread supply across five identical tranches over roughly four weeks, and every one of them landed on Solana.
USDC held its $1 peg through the whole stretch.
It's the second-largest stablecoin by market capitalization, and it's backed by reserves held at traditional financial institutions, which is what anchors the token to its dollar value.
A mint isn't the same as new money
The caveat here matters more than the headline number. A mint doesn't automatically mean new money has entered the market, because freshly minted tokens can sit in reserve at the treasury instead of moving into circulation right away. So the on-chain data shows supply being created on Solana. It doesn't, by itself, show those dollars being spent, lent or traded.
What Crypto Briefing reads into it
Crypto Briefing argued that putting all five mints on the same chain points to where Circle expects demand for dollar liquidity to show up. That's the outlet's analysis. The outlet also noted that large USDC issuances have historically correlated with increased defi activity and trading volume, and it said more available USDC could lead to higher trading volume (and possibly higher yields) for people using defi apps on Solana.
Will that happen this time? The outlet's answer is that the real signal will be whether this USDC actually moves out of the treasury and into circulation. Until it does, what we've got is five 250 million USDC mints, all on Solana, sitting on the blockchain for anyone to track.
