Adam Back’s Bitcoin Treasury Company Seeks New Terms with Cantor for SPAC Merger
Bitcoin Standard Treasury Company (BSTR), founded by Blockstream CEO Adam Back, said it will negotiate amended terms with Cantor Equity Partners I for a 2025 SPAC merger and related public offering, citing market conditions. A Friday shareholder meeting was postponed indefinitely. The prior deal involved 30,000+ BTC and $1.5B PIPE financing. BSTR and Cantor did not disclose new terms.

Why it matters
The scrapping of original terms and indefinite postponement raise uncertainty around deal completion and the timing of any public offering, increasing event-risk for any BSTR-linked trading and PIPE-related expectations.

Market effects
