Circle Issues $1.5 Billion in USDC on Solana Within 24 Hours

Circle issued $1.5 billion in USD Coin (USDC) on Solana in six transactions over a 24-hour period ending Oct. 22, marking a substantial short-term increase in the amount of the stablecoin issued through the network. Each of the six transactions was $250 million, totaling $1.5 billion.

The issuance is one day’s activity within a much larger 2026 total. Circle’s cumulative USDC issuance through Solana for the year reached $110.51 billion as of Oct. 22, a separate figure covering activity across the year rather than the same 24-hour window.

The six transactions were equal in size, and together they make up the daily total. The annual tally measures USDC issuance through Solana across 2026 to date. Read side by side, the figures show both the volume recorded in the 24-hour period and the cumulative amount issued on the network during the year. Both figures track issuance on the same network, with one covering 24 hours and the other the 2026 year to date.
