A year ago, Adam Back’s Bitcoin Standard Treasury Company had a plan that looked almost elegant: merge with a Cantor Fitzgerald-backed SPAC, go public holding more than 30,000 BTC, and raise up to $1.5B in additional capital through a PIPE financing round to keep stacking sats at institutional scale. It was poised to become one of the largest public Bitcoin treasury vehicles on the planet.

BSTR and Cantor Equity Partners I (CEPO) formally announced on July 8 that they will not proceed with the original merger agreement. The PIPE financing has been canceled. The shareholder meeting has been postponed indefinitely. The companies say they’re seeking new terms.

What went wrong

When BSTR’s merger was first structured in July 2025, the deal economics made sense because the vehicle traded at a premium to its underlying Bitcoin holdings. Investors were willing to pay more than the net asset value of the Bitcoin inside the wrapper, which gave the SPAC structure its financial logic.

Then Bitcoin’s price fell. Roughly 40–50%, according to market reporting.

When a Bitcoin treasury vehicle’s discounted market value drops below its net asset value, there’s no economic incentive for new investors to participate in a capital raise. The PIPE financing, designed to pull in up to $1.5B from institutional investors to fund further Bitcoin acquisitions, became impossible to execute under those conditions.

BSTR’s Bitcoin stash, once valued at more than $3.5B, shrank dramatically alongside the price decline. The treasury that was supposed to be the foundation of a publicly traded Bitcoin giant became the very reason the deal couldn’t close.

The SPAC problem gets worse

The BSTR-CEPO deal was one of the most ambitious attempts to use SPAC mechanics to create a public Bitcoin treasury company. Adam Back, a legendary figure in Bitcoin’s history whose work on Hashcash is cited in Satoshi Nakamoto’s original whitepaper, brought enormous credibility to the venture. Cantor Fitzgerald, one of Wall Street’s most established financial firms, provided the institutional infrastructure.

The deal’s collapse highlights a fundamental tension in Bitcoin treasury models. Companies like MicroStrategy (now Strategy) pioneered the concept of holding Bitcoin on a corporate balance sheet, but they did so as already-public companies with existing revenue streams. BSTR was trying to go public with Bitcoin as essentially its only asset, which works beautifully in a bull market and becomes an existential problem in a bear one.

What this means for investors

The PIPE investors who were presumably lined up to contribute up to $1.5B clearly decided the risk-reward calculus no longer justified participation.

The postponement of the shareholder meeting “indefinitely” rather than outright termination of all discussions suggests BSTR and CEPO may try to restructure the deal at different terms. But indefinite postponement in deal-making often functions as a polite way of acknowledging that the original vision isn’t coming back anytime soon.

Institutional investors considering exposure to Bitcoin treasury models would be wise to stress-test their assumptions against exactly this scenario: what happens to the vehicle’s economics when Bitcoin drops 40–50% and the premium disappears? BSTR just provided a real-world case study.
