USDC minting climbs to $1B in 24 hours as Circle fuels Solana liquidity

Dollar liquidity is surging across crypto markets as usdc minting accelerates, with Circle pushing another $1 billion of regulated stablecoins on-chain within a single day.

Circle adds $1 billion USDC in one day

On-chain data from Lookonchain shows that Circle minted roughly $1 billion in new USD Coin over the past 24 hours. TechFlow News, citing Lookonchain’s monitoring, reported two large mints of $500 million each, lifting total 24-hour issuance to $1 billion.

Moreover, this latest wave adds to an already heavy minting pace on the Solana network in early 2026. The activity underscores how Circle continues to route large flows onto Solana, which has become a preferred venue for high-speed stablecoin settlement.

Solana sees record weekly USDC deployment

Lookonchain previously flagged similar spikes, including a single-day period where Circle minted about $1.25 billion USDC on Solana. It also noted a stretch when Circle and Tether together issued roughly $17.25 billion in new stablecoins in the weeks after October 2025 market turbulence.

Furthermore, OnchainLens data cited by Phemex indicates that Circle has minted around $3.25 billion in USDC on Solana alone during the past seven days. Those mints came through repeated $250 million transactions, marking Circle’s largest weekly stablecoin deployment on that network so far this year.

Size and speed highlight institutional liquidity demand

The cadence and magnitude of the latest $1 billion issuance suggest it is not driven mainly by fragmented retail activity. Past episodes where Circle created $500 million to $1.25 billion in hours have usually aligned with liquidity provisioning for centralized exchanges, ETF custodians or stablecoin arbitrage desks.

That said, coverage of earlier alerts emphasized that fast, billion-dollar issuance bursts tend to precede deeper order books and wider USDC routing. They typically expand stablecoin usage across derivatives venues, lending markets and perpetual futures platforms, rather than reflecting short-lived speculative frenzies.

USDC leads stablecoin supply growth in 2026

More broadly, data compiled by Artemis and reported by Analytics Insight indicate that USDC has posted the largest net stablecoin supply increase of 2026 so far. Through March, circulating supply is up about $4.5 billion, even as rivals such as USDT saw net outflows of roughly $2 billion.

A separate dashboard from MEXC shows USDC’s market cap hovering near $73 billion, with 24-hour trading volume around $4.48 billion. Moreover, more than 250 applications now use the token as base collateral or a primary trading pair, reinforcing its status as regulated liquidity infrastructure for both centralized and decentralized markets.

What is driving the new $1 billion surge?

Circle does not pre-announce client-driven issuance, but the pattern fits several institutional use cases. These include centralized-finance inventory replenishment, on-chain basis strategies, arbitrage, and large over-the-counter settlements that require immediate, programmatic access to dollar liquidity.

CoinMarketCap’s research arm recently highlighted massive stablecoin issuance and centralized exchange inflows tied to USDC, arguing that such trends reflect capital preparation for deployment. However, the data suggest this capital is being staged for professional trading and market-making rather than purely for speculative retail flows.

Institutional rails increasingly favor USDC

Coverage of a prior $750 million USDC mint that opened 2026 on Solana framed those large transactions as clear liquidity signals. They drew institutional attention to where fresh stablecoin capital was being parked and how it was eventually deployed across trading and lending venues.

In that context, the latest wave of usdc minting, combined with March data showing USDC leading all major stablecoins in net new supply, points to a clear preference from deep-pocketed players. At least for now, institutions appear to be choosing Circle’s regulated dollar rails as their primary channel for moving size into crypto markets.

Overall, sustained large-scale issuance, rising market share and heavy Solana activity together confirm that USDC has become a core piece of dollar liquidity plumbing across the digital asset ecosystem.
