Circle Internet Group (ticker CRCL) went public on June 5, with its IPO priced at $31 per share. The stock surged nearly 200% shortly after listing, reaching around $115 per share, giving the company a market capitalization of about $25 billion. Circle powers $USDC, the world's second-largest U.S. dollar-backed stablecoin, with a market cap of approximately $61 billion. Following the IPO, ProShares and Bitwise have filed for ETFs based on CRCL stock. ProShares filed for a leveraged ETF, the ProShares Ultra CRCL fund, which aims to deliver twice the daily performance of Circle's Class A shares. Bitwise filed for the Bitwise CRCL Option Income Strategy ETF, which uses a covered call options strategy to generate income and limit downside risk. Both ETF filings have an effective date of August 20, 2025. $USDC was created in 2018 through a collaboration between Circle and Coinbase, with Circle taking full control over $USDC issuance and governance in 2023 after Coinbase acquired an equity stake in Circle.
