TL;DR

  • Cantor Equity Partners and Adam Back's Bitcoin Standard Treasury said they will not complete their SPAC merger on the existing terms.
  • The parties indefinitely postponed the July 10 CEPO shareholder meeting and said the pending private placements will not be required to close.
  • The original proposal paired 30,021 BTC with up to $1.5 billion of PIPE financing, a structure now subject to renegotiation.
  • The update puts the terms, financing and timetable for one of the biggest planned corporate Bitcoin treasuries back in play.

NEW YORK, July 10, 2026

Adam Back’s Bitcoin Standard Treasury and Cantor Equity Partners I will not complete their proposed SPAC merger on the original terms, shelving a plan that paired 30,021 BTC with up to $1.5 billion in financing and indefinitely postponing a July 10 shareholder vote.

The companies said they are discussing a revised structure for the transaction, but did not disclose new economics, a new vote date or a closing target. The pending private placements under the existing subscription agreements will not be required to close, according to Cantor’s July 8 announcement.

The update lands as Bitcoin recovered to about $64,325 on July 10 after trading as low as $58,573 on June 30. CEPO shares traded around $10.50 on July 8, while DefiLlama listed BSTR’s previously announced 30,021 BTC at about $1.93 billion.

In its Form 8-K, Cantor said CEPO and BSTR will not complete the business combination under the terms first set out in July 2025. The filing said any revised agreement would require additional SEC materials.

The distinction is central. BSTR has not said it is abandoning a public listing or its Bitcoin treasury strategy. It has said the original deal, its private-placement structure and the planned shareholder vote no longer work as drafted.

Daily Crypto Briefs recently covered Strategy’s $216 million Bitcoin sale, a separate reminder that corporate Bitcoin vehicles are now judged as much on their financing structures as on the number of coins they hold.

What remains unknown is whether BSTR’s 30,021 BTC starting reserve, its planned Nasdaq ticker or any portion of the original capital plan will survive the negotiations. Those details now depend on an amended agreement and new filings.

BSTR Scraps Its Original Bitcoin SPAC Terms

Cantor and BSTR said their revised structure is intended to better reflect current market conditions. That is the only explanation the parties gave for discarding the existing transaction terms.

The shareholder meeting had already moved twice. It was first set for June 26, then postponed to July 2 and then to July 10 before the indefinite delay, according to the companies’ announcements.

CEPO public shareholders do not have to act now, the company said. Shares previously submitted for redemption will be returned and will not be redeemed, removing a near-term decision point for holders while the parties negotiate.

The July 8 filing also makes clear that a replacement is not assured. It warns that a revised structure may not be agreed, may not close even if signed, or may not close before CEPO’s business-combination deadline.

That is a different risk profile from an ordinary Bitcoin purchase. The value of any future public BSTR security will depend on Bitcoin, the merger terms, investor redemptions, the financing and the ability to maintain a listing.

The Original Plan Put 30,021 BTC and $1.5B at Stake

The original BSTR announcement proposed 25,000 BTC from founding shareholders and 5,021 BTC through a Bitcoin-denominated private placement. That total would have made it one of the largest public corporate Bitcoin treasuries at launch.

The fiat side was equally significant. The proposal included up to $400 million in common equity, up to $750 million of convertible senior notes and up to $350 million of convertible preferred stock, for a maximum $1.5 billion PIPE package. It also allowed for up to roughly $200 million from CEPO, subject to redemptions.

Adam Back, the Blockstream co-founder and Hashcash inventor, was set to lead BSTR as chief executive, with Sean Bill as chief investment officer. Their plan went beyond holding BTC: BSTR said it intended to add Bitcoin capital-markets and advisory services.

Those proposed terms explain the interest in the reset. A 30,021 BTC balance sheet is sizable, but the cancelled financing could have altered how much leverage, dilution and cash funding sat behind that reserve.

The sharpest question is therefore not whether BSTR still has a Bitcoin thesis. It is whether the revised agreement gives public investors a clearer path to the same treasury exposure with financing terms that the market will accept.

Bitcoin Treasury Deals Face a Capital-Structure Test

Bitcoin treasury companies appeal to investors who want market-traded BTC exposure alongside management’s ability to issue equity, raise debt or run a balance sheet. The trade-off is that each financing layer can introduce dilution, refinancing risk and pressure on the equity premium.

Strategy’s latest sale showed how those choices can become a market event. So did the rapid expansion by miners into data-center contracts, including MARA’s 2-gigawatt Texas campus plan, where the market must weigh infrastructure financing against Bitcoin exposure.

The BSTR deal was also more complex than a simple cash SPAC. It combined founder-contributed BTC, an in-kind Bitcoin PIPE, common equity, convertible notes and preferred stock. Rewriting that mix could change the economics for every party, even if the headline Bitcoin reserve remains close to the original plan.

The backdrop has made that exercise harder. Bitcoin’s move from $58,573 on June 30 to above $64,000 on July 10 eased immediate price pressure, but it did not eliminate uncertainty over equity premiums, investor redemptions or the cost of capital for treasury companies.

Crypto sentiment remains cautious. Alternative.me showed a Fear and Greed Index score of 23, classified as Extreme Fear, on July 10.

The next confirmed catalysts are a revised transaction announcement, any amended SEC registration statement, a rescheduled CEPO meeting and disclosure of which private placements, if any, return. Until then, BSTR’s proposed reserve remains an announced plan, not a completed public-company treasury.
