Jack Mallers is out at Twenty One Capital, Strike is staying private, and Tether's plan to weld a bitcoin treasury, payments company, and miner into one listed business has come apart.
Seven months. That's how long Jack Mallers lasted as CEO of Twenty One Capital before walking out of the public company he helped launch. Twenty One said Raphael Zagury, a board member and the CEO of the team managing Elektron Energy, took over on July 20, 2026. Mallers is going back full time to Strike, the bitcoin payments company he actually built.
The market didn't treat that as a clean handover. Decrypt reported that XXI shares fell nearly 18% on Tuesday and were down more than 80% from last year's highs. Stocktwits described the move as a slide to an all-time low. You don't need a complex theory for that reaction. A bitcoin treasury company losing the founder who gave it an operating-company story is not a minor personnel change.
The tension is now out in the open, even if the filing language stayed tidy. Twenty One's SEC disclosure said Mallers' departure was not related to disagreements over operations, policies, practices, financial disclosures, accounting, or legal matters. That's the official version. Mallers, in a video statement posted after the announcement, gave you the more useful one: he said he had wanted to build bitcoin businesses producing cash flow alongside a large bitcoin balance sheet, but over time, the board and he did not agree on that path.
That difference matters. A treasury company is a bet on bitcoin's price, amplified. A payments and lending business using bitcoin is harder to build, but at least it gives investors something to judge besides the next BTC candle. Mallers was selling the second story. Tether now looks more comfortable with the first.
The Deal That Fell Apart
The leadership change landed next to a bigger reversal. In April, Tether proposed combining Twenty One, Strike, and Elektron Energy into a single publicly traded bitcoin company. Bloomberg reported at the time that the proposed structure would put Twenty One's bitcoin treasury, Strike's financial services business, and Elektron's mining operation under one roof. It was an obvious pitch: don't just copy MicroStrategy, add the operating businesses that might make the model look less like a wrapped bitcoin trade.
Now Strike is out. Tether said on July 21 that Twenty One and Strike had determined Strike was best positioned as an independent business and were no longer contemplating a combination. CoinDesk reported that a possible two-way combination with Elektron remains under evaluation, but the original three-way plan is dead. That's the core fact here.
Twenty One still has the bitcoin. BitcoinTreasuries.net lists the company at 43,514 BTC, making it one of the largest public corporate holders behind Michael Saylor's Strategy. But the part of the pitch that made Twenty One feel different - Mallers and Strike - is no longer inside the public vehicle. You can call that strategic focus if you like. Investors heard subtraction.
Tether has also tightened its control. A May SEC filing shows Tether International bought SoftBank's remaining 89,106,748 Class A shares, while SoftBank's Class B shares were cancelled and its board representatives resigned. That left Tether as the controlling shareholder behind Twenty One before Mallers left and before Strike stepped away from the merger talks.
A Treasury Company After All
Twenty One was supposed to be the principled alternative to Strategy. Saylor's company piles into bitcoin and finances more buying through debt and equity. Critics have long treated that as something close to a bitcoin fund with a legacy software business bolted on. Twenty One had Tether, Cantor Fitzgerald, SoftBank, a large BTC stack, and Mallers. The Mallers part mattered because Strike had already built real bitcoin payment rails.
That distinction has now thinned out. Mallers thought he was building the platform. The board appears to have wanted the treasury. Zagury, whose background sits closer to Elektron and bitcoin infrastructure, is a more natural leader for a company still talking about mining, lending, capital markets, and bitcoin accumulation.
Frankly, this is the question you should care about if you bought into the bitcoin treasury wave: where is the business after the balance sheet? If the founder with the clearest operating-company credentials leaves after seven months, the operating layer was probably never as central as the launch story suggested. The rest was branding around the BTC pile.
Strike remains private, and that is where Mallers' real strength sits. Its payments network, Lightning infrastructure, and lending ambitions are no longer part of the Twenty One transaction. Twenty One can still become a pure bitcoin treasury company with a mining angle, but it now has to prove that is enough at roughly $4 and change a share. So far, the market isn't giving Zagury the benefit of the doubt.
