Circle minted roughly $1 billion in new USDC over 24 hours, underscoring a fresh wave of institutional dollar demand across crypto rails — particularly on Solana and centralized venues.
On-chain watcher Lookonchain (reported by TechFlow News) flagged two jumbo mints of $500 million apiece that pushed 24‑hour issuance to about $1 billion. The burst adds to an already hot start to 2026 for USDC: Circle’s year‑to‑date circulating supply has risen roughly $4.5 billion through March, according to data compiled by Artemis and Analytics Insight.
Solana has been a major recipient of the new supply. OnchainLens data cited by Phemex shows Circle minted about $3.25 billion in USDC on Solana in the past seven days via repeated $250 million transactions — the issuer’s largest weekly deployment on the network so far this year. Lookonchain previously highlighted other big spikes, including a single day when Circle minted ~ $1.25 billion on Solana, and a post‑October 2025 episode when Circle and Tether together issued roughly $17.25 billion in new stablecoins amid market turbulence.
The cadence and scale of these mints make retail trading an unlikely driver. Historically, $500 million–plus prints in short windows tend to coincide with institutional activity: liquidity provisioning for centralized exchanges, ETF custodians replenishing inventories, basis/arbitrage desks, large over‑the‑counter settlements, or other programmatic dollar needs. MEXC and KuCoin coverage of earlier alerts noted that rapid, billion‑dollar issuance often precedes deeper order books and wider USDC routing across derivatives, lending markets and perpetuals venues.
Market metrics underline USDC’s central role in liquidity plumbing. MEXC’s dashboard puts USDC market cap near $73 billion with about $4.48 billion in 24‑hour trading volume, and more than 250 applications using USDC as base collateral or a primary trading pair. CoinMarketCap’s research team argued that “massive USDC minting and inflows to exchanges like Binance” reflect capital preparation for trading or deployment rather than speculative retail chasing. Coinfomania similarly framed a prior $750 million Solana mint that kicked off 2026 as a “strong liquidity signal” that draws institutional attention to where new stablecoin capital is parked.
Circle does not publicly pre‑announce client‑driven mints, so observers infer intent from patterns and recipients. For now, the latest $1 billion issuance reinforces a trend: deep‑pocketed players appear to be favoring Circle’s regulated dollar rails to move large amounts into crypto markets quickly and programmatically.
