Cantor Fitzgerald is reportedly finalizing a $4 billion SPAC deal to acquire billions in Bitcoin, making it one of the largest crypto buys ever by a Wall Street firm. The deal involves Cantor Equity Partners 1, which raised $200 million in January, and crypto pioneer Adam Back, founder of Blockstream.

Back is expected to contribute up to 30,000 Bitcoin, worth over $3 billion, and the vehicle plans to raise an additional $800 million to grow the crypto investment. In return, Back and Blockstream Capital will receive shares in the newly named BSTR Holdings.

This follows Cantor’s $3.6 billion Bitcoin venture with SoftBank and Tether in April, potentially pushing total crypto investments near $10 billion. The move signals Cantor’s aggressive expansion in crypto under new chairman Brandon Lutnick and highlights rising institutional interest during “crypto week” in Washington.
