Bitcoin Standard Treasury Company nears SPAC merger completion with Cantor Equity Partners by month-end

Adam Back’s Bitcoin Standard Treasury Company is on track to close its SPAC merger with Cantor Equity Partners I by the end of this month, creating what could become one of the largest publicly traded Bitcoin treasury vehicles on the planet.

The deal would see BSTR debut on public markets holding an initial 30,021 BTC. That’s enough to rank it as the fourth-largest public Bitcoin treasury at launch.

A billion-dollar bet with Bitcoin as collateral

The merger was first announced on July 17, 2025, with an ambitious financing structure that blends old-school Wall Street mechanics with something far more native to crypto.

BSTR has lined up plans for up to $1.5 billion in financing. The deal includes a landmark in-kind equity PIPE consisting of 5,021 BTC, valued at approximately $600 million. Investors aren’t just writing checks in dollars — they’re contributing actual Bitcoin directly into the company’s equity raise.

The SPAC trust itself is expected to contribute up to roughly $200 million, though that figure is contingent on redemptions.

The team and the thesis

BSTR’s leadership includes CEO Adam Back, CIO Sean Bill, President Katherine Dowling, and CFO Bob Stefanowski. Back is one of the more respected cryptographers in Bitcoin’s history, cited in the original Bitcoin whitepaper for his work on Hashcash, a proof-of-work system that predates Bitcoin itself.

The company has described itself as aiming to become an “actively managed Berkshire Hathaway of Bitcoin,” focusing on generating operational income from its Bitcoin holdings rather than passive accumulation. BSTR plans to grow beyond 50,000 BTC through active management of its assets post-merger.

Where the SPAC process stands

BSTR has already filed its S-4 registration statement, and SEC review is reportedly nearing completion. Assuming no last-minute complications, the end-of-June timeline appears intact.

What this means for investors

The redemption rate on the SPAC trust will be one of the first real signals of investor conviction. A low redemption rate would confirm strong demand. A high rate, where existing SPAC shareholders cash out rather than hold through the merger, would suggest the market is pricing in more risk than the headline numbers imply.

If BSTR successfully closes a $600 million Bitcoin-denominated equity raise, it could open the door for future deals where BTC functions as direct investment capital in public market transactions. BSTR’s entry as the fourth-largest public Bitcoin treasury would immediately reshape the leaderboard, with a stated goal of surpassing 50,000 BTC.
