Multiple independent and reasonably authoritative sources report that Circle minted approximately 250 million USDC on the Solana blockchain. CoinGecko’s market pages for USDC in both USD and JPY contexts mention this minting event, and Bitget publishes two separate news articles detailing the same figure with contextual analysis of its market impact. Cointelegraph's Telegram channel also directly confirms the 250M mint, and Phemex News cites commentary from a Circle market team member regarding the issuance. Reddit's r/CryptodailyBuzz post discusses on-chain transaction data showing this mint, lending weight from blockchain evidence. The majority of these sources are consistent with each other in both the figure and the blockchain (Solana). While there are mentions in other outlets of different mint sizes (e.g., 500M or 1B), these appear to refer to other separate events or aggregated mints across times rather than contradicting this specific instance. Given the convergence of multiple independent primary and industry sources corroborating the same transaction details, the probability that the statement is true is high, with only minor uncertainty due to occasional reporting of larger mints in other contexts.
