A special purpose acquisition company (SPAC) called Circle Acquisition has reportedly filed for a $150 million initial public offering targeting digital assets, technology, and healthcare sectors. The entity is unrelated to Circle Internet Group, the company behind the USDC stablecoin, which completed a $1.1 billion traditional IPO in June 2025 at $31 per share. The broader SPAC market faces increased regulatory scrutiny from the SEC, which has implemented stricter rules requiring more detailed projections and conflict-of-interest disclosures from SPAC sponsors. As of September 15, 2026, no verifiable SEC filings for Circle Acquisition or its close variants had surfaced in connection with the reported $150 million IPO.
