Jack Mallers Exits Twenty One Capital as Tether’s Three-Way Bitcoin Rollup Unravels
Jack Mallers leaves Twenty One Capital to refocus on Strike as Tether abandons plans to merge Twenty One, Strike, and Elektron Energy. XXI slides nearly 18% amid a strategy reset.

The bet on a single, vertically integrated “Bitcoin supercompany” is off. Jack Mallers has resigned as CEO of Twenty One Capital and is returning full-time to Strike, while Tether has shelved its plan to combine Twenty One, Strike, and Elektron Energy into one publicly traded Bitcoin conglomerate.
Investors voted with their feet. Twenty One’s stock fell nearly 18% on Tuesday, extending a slide that has left shares more than 80% below last year’s peak. The company—taken public on the NYSE via SPAC in December 2025—had been marketed as a clean vehicle for Bitcoin exposure: a listed treasury that accumulates BTC so equity buyers don’t have to. It still holds 43,514 BTC, worth over $4 billion at current prices, placing it second among public companies for Bitcoin holdings, just behind Michael Saylor’s firm that pioneered the corporate BTC treasury playbook in 2020.
Here’s the pivot that actually matters: Twenty One is shifting from an identity built around aggressive Bitcoin accumulation to one emphasizing institutional discipline and cash-flow accountability. Raphael Zagury, founder of Elektron Energy and former executive at Deutsche Bank, Merrill Lynch, and Goldman Sachs, takes over as CEO. His message contrasts Mallers’ “stack sats” ethos; he told investors the company should be evaluated on the cash it produces and how prudently it deploys capital.
Why that change cuts deep - Business reality: Merging mining, payments, and treasury under one ticker sounds tidy, but incentives often diverge. Miners live and die by energy economics and hash price. Payments platforms like Strike—now remaining independent and operating in 100+ countries with payments and lending—compete on UX, compliance, and partnerships. A treasury vehicle optimizes for BTC beta and capital markets signaling. Forcing them together can dull each arm’s edge and muddle valuation. - Market psychology: Many shareholders bought Twenty One for pure Bitcoin exposure. A turn toward “operating company” metrics introduces execution risk and reduces narrative clarity. That helps explain the stock’s sharp reaction and its broader range—from a 52-week high of $31.51 to a low of $4.81. - Technology and operations: Integrating mining infrastructure (Elektron Energy), a global payments stack (Strike), and a balance-sheet strategy is nontrivial. Different risk clocks, compliance regimes, and data pipelines rarely align on quarter-by-quarter reporting. Fragmenting them back into focused units may speed decision cycles and reduce integration drag. - Governance and capital allocation: Tether had tightened its grip in May 2026 by purchasing SoftBank’s roughly 25% stake, which SoftBank had originally bought for $999.3 million. Greater control can streamline decisions, but it also concentrates responsibility for capital allocation. A cash-flow mandate provides a clearer yardstick than “more BTC” alone, especially in choppy markets.
What’s next - Strike remains a standalone company. Mallers framed the move as recommitting to his life’s work on Bitcoin payments, leaving little doubt he wants to keep product velocity high and optionality intact. - Twenty One and Elektron are in early talks on a potential two-way deal, though nothing is agreed or guaranteed. - Expect investors to recalibrate how they value Bitcoin treasuries: less on headline BTC counts, more on sustainable cash generation and disciplined deployment. In a cycle where liquidity ebbs and flows, that’s a healthier way to earn trust.
Abandoning the rollup isn’t a failure of conviction in Bitcoin. It’s an admission that capital markets tend to reward clarity of purpose. In this sector, clean stories often travel farther than complex integrations.
