Circle Mints $3.5B USDC on Solana in One Week as Stablecoin Demand Jumps

Circle minted about $3.5 billion in USDC on Solana last week, including a $1 billion on-chain mint on June 16. Gross USDC issuance on Solana has already topped $64 billion in 2026, even though it's only early July. USDC activity on Solana is being fueled by broad demand across DeFi trading, cross-border payments, and institutional settlement flows. Solana's low fees and high throughput make it well suited to the high-frequency transfer patterns stablecoin users typically rely on. Each USDC token corresponds to a dollar (or dollar-equivalent reserves) deposited by a customer seeking on-chain "digital dollars." Minting $3.5 billion in a week points to a comparable amount of incremental demand entering the system. The $1 billion mint executed as a single transaction on June 16 stands out, as activity at that scale is generally associated with institutional or enterprise use rather than retail trading on decentralized exchanges. Circle has also strengthened institutional mint-and-burn rails through a partnership with BNY Mellon, one of the world's largest custodial banks. The arrangement spans both Solana and Ethereum, giving institutions a familiar custody setup for managing USDC at scale. Circle has not publicly commented on the specific June minting events. The figures are based on data from real-time on-chain monitoring platforms. Investor takeaways: With $64 billion in gross USDC issuance on Solana so far in 2026, the network is increasingly viewed as a viable venue for high-volume stablecoin activity. For SOL holders, deeper USDC liquidity can translate into more on-chain transactions, stronger DeFi participation, and additional incentives for developers to build on Solana. Stablecoin throughput is often seen as a clearer signal of real economic usage on a blockchain than speculative token trading, which can fade quickly. While Tether's USDT remains the global market-share leader, USDC's expansion on Solana—supported by Circle's regulatory-first positioning and institutional partnerships—is establishing a distinct growth channel.
