Twenty One Capital Inc. (XXI) had a rough Tuesday. Shares plunged nearly 10% after the company announced that founder and CEO Jack Mallers was stepping down and that its ambitious three-way merger—designed to create a unified Bitcoin platform—was dead.

Mallers resigned after disagreements with the board over corporate strategy, according to the company. He's going back to focus full-time on Strike, the Bitcoin payments network he co-founded. Strike was supposed to be part of the merger, but now it will remain independent, leaving Twenty One without that transaction network for its planned Bitcoin-native platform.

The merger's other leg, Bitcoin miner Elektron Energy, is also off the table for now. But there's a twist: Twenty One might still acquire Elektron—it's just at a very preliminary stage, and there's no guarantee a deal will happen. And even if it does, it'll face extra scrutiny because the new CEO, Raphael Zagury, co-founded and leads Elektron. That's a related-party transaction, so the board will have to sign off.

Zagury, who took over on July 20, is a Wall Street veteran. He's held senior roles at Goldman Sachs, Deutsche Bank, and Merrill Lynch, and co-founded boutique firm One Partners, Brazilian lender OpenCo, and—yes—Elektron Energy. He was already on Twenty One's board as an independent director and interim Audit Committee chair, but he resigned those committee roles to become CEO.

So what's the new plan? Zagury is shifting Twenty One's strategy away from the consumer-facing Strike combo and toward building an institutional Bitcoin operating company. Think cash flow, discipline, and capital allocation—not flashy mergers.

“Twenty One holds one of the largest Bitcoin balance sheets in the public markets,” Zagury said. “My job is to build the operating company around it, with the discipline, governance, and executional rigor of an institution.”

Going forward, Twenty One plans to focus on positive cash flow, Bitcoin-backed financial products, and corporate lending. It's a sharp pivot from the grand unified platform vision, and investors are clearly nervous. Shares were down 9.78% at $4.80 at the time of publication, according to market data.

Whether Zagury can pull off this institutional makeover remains to be seen. But for now, Twenty One is a company in transition—and the market is pricing in a lot of uncertainty.
