Jack Mallers Steps Down as Twenty One CEO to Refocus on Strike

High attention and emotional sentiment detected.

Mallers shared the news in a tweet at 12:27 UTC on July 21, 2026. He said he will help with the transition, then focus full time on Strike. According to the same thread, the planned merger between Strike and Twenty One is now off.

What Jack Mallers Said

Mallers framed the exit as a personal decision about focus. “I’ve decided to step down as CEO of Twenty One,” he wrote. “This wasn’t an easy decision, but it was the right one.”

He then made his priorities clear. “My life’s work remains Bitcoin. My Bitcoin company is @Strike. The work continues,” he added in the same post on X.

In a follow-up, he pushed back on the idea that the company is finished. “To be clear, Twenty One isn’t ‘over’,” he wrote. Still, he acknowledged friction. “The board and I could not agree about the road ahead,” he said.

He closed on a supportive note. “XXI was built by Bitcoiners, for Bitcoiners,” he said. He added that he looks forward to watching the next phase of growth at XXI.

Raphael Zagury Takes Over at Twenty One

Zagury moves up from the board to run the company. He also serves as CEO of Elektron Energy. So he arrives with a finance and operations background, not a founder’s profile.

His stated goal is discipline. “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.”

That framing matters for a treasury company. The balance sheet already exists. So the next phase is about building cash-generating operations around 43,514 BTC. The team must build a business, not just buy more coins.

The model has a clear goal. It aims to grow Bitcoin per share over time. Operating cash flow can then fund more BTC purchases, which compounds the holdings. Zagury’s job is to make that engine run.

The Strike Merger Is Off

The most concrete fallout is corporate. Strike and Twenty One will not merge. That reverses plans floated in April 2026 that also involved Elektron Energy.

Strike stays independent as a result. Mallers keeps his Lightning-based payments company separate from the public treasury vehicle. Now he runs only Strike day to day.

For context, that April plan would have combined payments, a Bitcoin treasury, and energy operations under one roof. Now those pieces stay apart. Each leadership team charts its own course.

How Twenty One Became a Bitcoin Treasury Giant

Twenty One is a Bitcoin treasury company, which means it holds BTC as its primary reserve asset. According to bitcointreasuries.net, its 43,514 BTC rank it as the second-largest public corporate holder.

The company came together with backing from Tether and Bitfinex, plus early support from SoftBank. It then went public through a SPAC merger with Cantor Equity Partners. That deal closed in December 2025 and listed the firm on the NYSE as XXI.

Mallers took the CEO role at that December close. Meanwhile, Tether tightened its grip in May 2026. It bought out SoftBank’s stake and became the dominant shareholder.

So far, the treasury has stayed roughly flat. The company disclosed no major Bitcoin additions after about July 2025. No fresh reserve attestation has arrived with this leadership change.

Board Disagreement or Personal Focus?

The question of why Jack Mallers steps down has two answers. Two narratives now sit side by side. The official framing is personal clarity and a return to Strike. Yet Mallers’ own follow-up points to a split with the board over strategy.

Some users on X backed his choice as a mature move toward focus. Others were harsher. One account jabbed that leadership “paid yourself millions while shareholders got rekt.”

The debate did not split cleanly. Some accounts stayed bullish on the separation. They argued that sharper focus helps both Strike and XXI in the long run.

The skepticism has a basis in the stock. XXI shares recently traded near $5. That is down sharply from a post-listing high above $50, so the frustration makes sense. The slide has fueled shareholder criticism for much of the year.

Key details remain unknown. The announcement did not specify whether Mallers keeps a board seat. It also left his equity stake and the exact internal catalyst unconfirmed.

Market Reaction and What Comes Next

The immediate market reaction looks muted. Reporting so far shows no sharp post-announcement spike in XXI. Broader Bitcoin price action does not appear tied to the news.

Zagury now owns the strategy question. Investors will watch for the promised disclosures. They want to see how Twenty One turns a large Bitcoin balance sheet into a working business.

The news that Jack Mallers steps down leaves a clean split. For now, the story reads as builder versus vehicle. Mallers is betting his name on Strike. Zagury inherits the public company and must prove the treasury model can stand on its own.
