Cantor Fitzgerald is finalizing a landmark $4 billion Bitcoin acquisition deal with Blockstream founder Adam Back, according to a Financial Times report. The transaction would represent one of Wall Street’s largest cryptocurrency investments to date, signaling institutional confidence in digital assets. This marks Cantor’s second major Bitcoin venture this year, following a $3.6 billion deal with SoftBank and Tether in April.
The deal involves Cantor Equity Partners 1, a special purpose acquisition company (SPAC) that raised $200 million in January. Under the draft agreement, Adam Back would contribute up to 30,000 Bitcoin (valued at over $3 billion) to the SPAC in exchange for equity. The vehicle plans to raise an additional $800 million to expand Bitcoin purchases, bringing the total transaction value to $4 billion.
Brandon Lutnick, chairman of Cantor Equity Partners and son of U.S. Commerce Secretary Howard Lutnick, is leading negotiations. The SPAC would be renamed BSTR Holdings upon deal completion, which sources indicate could occur as early as this week during what Republican lawmakers have dubbed “crypto week” amid digital asset legislation debates.

Cantor Fitzgerald’s Crypto Expansion
Cantor Fitzgerald has emerged as an aggressive institutional buyer in the cryptocurrency space throughout 2025. The firm’s previous $3.6 billion Bitcoin acquisition with SoftBank and Tether in April established its position as a major player. Combined with the current Back deal, Cantor’s total Bitcoin acquisitions this year could approach $10 billion through its BSTR Holdings and Twenty One Capital vehicles.
The Lutnick family has maintained a consistent pro-Bitcoin stance, with Commerce Secretary Howard Lutnick previously disclosing personal holdings in the asset. Brandon Lutnick’s leadership in these transactions demonstrates the firm’s strategic commitment to cryptocurrency despite market volatility. Cantor’s SPAC model allows it to leverage public markets for large-scale digital asset accumulation.
Recent crypto-focused deals by Cantor include:
- May 27 financing agreement with onchain asset manager Maple Finance
- Partnership with crypto brokerage FalconX
- April’s $3.6 billion venture with SoftBank and Tether
Adam Back and Blockstream’s Role
Adam Back, cited in Satoshi Nakamoto’s original Bitcoin whitepaper, brings significant technical credibility to the transaction. As founder and CEO of blockchain technology firm Blockstream, Back developed the Hashcash proof-of-work system that became foundational to Bitcoin’s mining mechanism. His contribution of up to 30,000 BTC represents one of the largest individual Bitcoin transfers to an institutional entity.
Blockstream Capital, Back’s crypto trading firm, would become a major shareholder in the newly formed BSTR Holdings through the share exchange agreement. This transaction aligns with Back’s history of pioneering cryptocurrency infrastructure, having co-founded Blockstream in 2014 to develop Bitcoin scaling solutions like the Liquid Network and satellite Bitcoin broadcasting.
The deal structure allows Back to maintain exposure to Bitcoin’s potential upside through equity in a regulated financial vehicle while providing Cantor with immediate access to substantial Bitcoin reserves. This model differs from traditional spot ETF investments by creating direct blockchain exposure without intermediary custodians.
Market Implications and Regulatory Context
The timing coincides with heightened cryptocurrency regulatory discussions in Washington, where Republican lawmakers have designated this period “crypto week” for digital asset legislation debates. The deal’s scale could influence ongoing policy conversations about institutional cryptocurrency ownership and SPAC structures for digital asset acquisition.
Market analysts note this transaction continues 2025’s trend of institutional Bitcoin accumulation during price consolidation periods. The $4 billion deal would rank among the top five largest Bitcoin acquisitions by traditional finance entities, comparable to MicroStrategy’s cumulative holdings. Such large-scale transfers from early adopters to institutional custodians represent a maturation phase for Bitcoin’s market structure.
SPAC transactions like Cantor’s have become an increasingly popular mechanism for institutional Bitcoin exposure, offering public market investors indirect access while avoiding the regulatory complexities of spot Bitcoin ETFs. The model allows traditional finance entities to accumulate cryptocurrency at scale while providing liquidity options through public markets.
Key transaction metrics:
| Component | Value |
|---|---|
| Bitcoin from Adam Back | 30,000 BTC (~$3B) |
| Additional capital raise | $800M |
| Total deal value | $4B |
| Cantor’s 2025 crypto total | ~$10B |
Industry observers suggest this deal could accelerate similar institutional moves, particularly among financial firms seeking cryptocurrency exposure without direct custody challenges. The transaction structure provides a blueprint for converting substantial cryptocurrency holdings into tradable equity while maintaining market exposure.
