Adam Back’s Bitcoin Treasury Firm Renegotiates SPAC Terms With Cantor

Bitcoin Standard Treasury Company (BSTR), founded by Blockstream CEO Adam Back, is seeking to renegotiate its proposed merger with Cantor Equity Partners I, a SPAC backed by Cantor Fitzgerald. In an announcement released Wednesday, BSTR and Cantor Equity Partners I said they have scrapped the original deal terms and will move into new negotiations, citing the need for provisions that “better reflected market conditions.”

The change arrives as investors watch SPAC-backed crypto-adjacent companies for signs of whether tokenization and Bitcoin-treasury themes can still clear public-market hurdles. A shareholder meeting scheduled for Friday to vote on the merger and related public offering has been postponed indefinitely, with the companies saying they will share further details later.

Key takeaways

• BSTR and Cantor Equity Partners I have terminated the original 2025 merger terms and will negotiate a revised agreement.
• The planned shareholder vote on the SPAC merger and public offering has been postponed indefinitely.
• BSTR’s initial structure included a contribution of more than 30,000 BTC plus $1.5 billion in PIPE financing.
• The U.S. SEC recognized the registration statement for the original deal in June, but the offering timeline has now stalled.
• The broader SPAC backdrop is under pressure after a Cantor-associated tokenization deal by Securitize began trading last week.

Merger terms scrapped, vote delayed indefinitely

According to the Wednesday update, BSTR and Cantor Equity Partners I decided to drop the original terms of their proposed business combination and negotiate a new set of provisions. The companies did not provide specifics on what would change, but they said the goal is to align the agreement more closely with current market conditions.

Because the shareholder meeting originally scheduled for Friday has been postponed indefinitely, the deal’s next steps are now uncertain. Both sides indicated they would provide additional information “in due course,” leaving investors to wait for details on the revised structure, timing, and any updated financing or equity economics.

What the original BSTR-Cantor framework included

The initial proposal contemplated a larger public-market launch for BSTR built around a Bitcoin treasury strategy. In the original deal, BSTR was set to contribute more than 30,000 Bitcoin (BTC) and $1.5 billion in PIPE (Private Investment in Public Equity) financing.

The SEC’s role was a key marker for progress: the regulator recognized the registration statement connected to the merger agreement in June. That recognition is often viewed by deal participants as an important step toward executing a SPAC-linked offering, which contributed to expectations that a public listing would follow soon after.

Now, with the shareholder vote delayed and the parties resetting negotiations, the original timeline appears to have been overtaken by the same “market conditions” rationale cited in the announcement.

SPAC flexibility and the shifting viability of “Bitcoin treasury” themes

While the BSTR update explains the immediate reason for renegotiation, the wider context is the scrutiny that Cantor SPAC structures have faced from industry observers.

Earlier coverage cited by Institutional Investor described Cantor as having “a lot of wiggle room” in SPAC transactions, moving beyond a narrow focus on Bitcoin treasury vehicles such as BSTR and Twenty One Capital. The report referenced Twenty One Capital’s completion of a $3.6 billion merger deal with Cantor in 2025, suggesting that the Cantor-backed ecosystem had been experimenting with broader or more flexible deal themes.

According to the same Institutional Investor piece, SPACInsider founder and CEO Kristi Marvin said that it was unclear whether a Bitcoin treasury-focused SPAC approach would remain attractive in the near term—adding that the outlook might look different once the next few months play out.

That tension helps frame what BSTR is now navigating: if market appetite for specific SPAC-linked crypto strategies has cooled or become more selective, even SEC-acknowledged registration steps may not be enough to guarantee deal execution on schedule.

Securitize’s Cantor-linked debut highlights the stakes for the category

The uncertainty around BSTR’s merger comes after Securitize, a tokenization company, made its debut on the New York Stock Exchange following a Cantor-related SPAC transaction.

Cointelegraph previously reported that Securitize received SEC approval for its SPAC deal with Cantor Equity Partners II in June and began trading on the NYSE about a week after shareholders signed off. Cointelegraph also noted that the shares started trading under the ticker SECZ.

In the days immediately following the listing, the price action underscored how quickly sentiment can shift. The article says the shares traded at $7.42 apiece on Wednesday, roughly 40% below their July 2 closing price of $12.30.

Taken together, Securitize’s early market performance may not directly determine BSTR’s outcome, but it illustrates the challenge of raising capital and maintaining investor confidence in public-market vehicles tied to digital asset infrastructure themes.

What investors should watch next

For BSTR and Cantor Equity Partners I, the next milestone will be the details of the revised merger terms—especially how the companies plan to rework financing and equity economics after scrapping the original agreement. Until a new shareholder process and timeline are established, investors will likely focus on whether the parties can rebuild deal certainty without losing market momentum.
