Transaction Overview: BSTR Goes Public via SPAC with 30,021 Bitcoin
Bitcoin Standard Treasury Company (BSTR) has signed a definitive agreement to merge with Cantor Equity Partners, a special-purpose acquisition company sponsored by an affiliate of Cantor Fitzgerald. Upon completion, BSTR will hold 30,021 Bitcoin on its balance sheet, positioning it as the fourth largest public Bitcoin treasury globally. This confirms a July 15 report that Cantor Fitzgerald was nearing a $4 billion deal with Adam Back.
The new entity will be led by Dr. Adam Back, CEO and co-founder of Blockstream, and Sean Bill, an institutional investor known for driving one of the first Bitcoin allocations by a U.S. public pension fund. Their combined expertise bridges the Bitcoin OG community with traditional capital markets.
Record-Breaking PIPE Financing: $1.5 Billion to Fuel Bitcoin Accumulation
The deal includes up to $1.5 billion in PIPE (Private Investment in Public Equity) financing—the largest ever announced in conjunction with a Bitcoin treasury SPAC merger. The structure includes:
- $400 million in common equity
- Up to $750 million in convertible notes
- Up to $350 million in convertible preferred stock
- 5,021 Bitcoin from in-kind PIPE contributions
- 25,000 Bitcoin from founding shareholders advised by Blockstream Capital
- Up to $200 million from CEPO, subject to redemptions
Notably, the convertible preferred stock is the first of its kind in a Bitcoin treasury SPAC merger, reflecting an innovative capital structure. Adam Back commented: "Bitcoin was created as sound money, and BSTR is being created to bring that same integrity to modern capital markets. By securing both fiat and Bitcoin funding on day one—including the first convertible preferred round—we are putting unprecedented firepower behind maximizing Bitcoin ownership per share while accelerating real-world adoption."
Leadership Team: Bridging Bitcoin OGs and Traditional Finance
Dr. Adam Back is a legendary Bitcoin developer, known for his Hashcash proof-of-work algorithm. Sean Bill represents the institutional adoption driver, having led one of the first Bitcoin allocations by a U.S. public pension fund. Brandon Lutnick, Chairman & CEO of Cantor Fitzgerald, stated: "As a long-time Bitcoin advocate, Cantor is incredibly proud to partner with Dr. Back, one of Bitcoin's leading luminaries. This historic transaction marks another step towards the integration of the Bitcoin economy and traditional finance."
Timeline and Use of Proceeds
The transaction is expected to close in Q4 2025, pending shareholder and regulatory approvals. Proceeds will be used to acquire additional Bitcoin and build Bitcoin-native capital markets and advisory solutions. Back contributes up to 30,000 Bitcoin (valued at over $3 billion) in exchange for equity in the renamed BSTR Holdings. With this listing, the public Bitcoin treasury landscape gains its fourth-largest player, offering traditional investors a convenient Bitcoin exposure vehicle.
