Twenty One Capital's New CEO Warns the Bitcoin Treasury Arbitrage Era Is Closing
Raphael Zagury, Twenty One Capital's new CEO, told a Miami audience two days after taking the job that the premium-funded Bitcoin treasury model can't generate easy returns forever, and that premiums across the sector should converge toward 1x.
Raphael Zagury took the job, then immediately told the market the trade that built the sector is running out of road.
Key takeaways
- Twenty One Capital's new CEO Raphael Zagury said publicly on July 22 that mNAV premiums across the corporate Bitcoin treasury sector should compress toward 1x as more companies copy the playbook.
- His answer is to pivot XXI from a passive accumulation vehicle into a Bitcoin operating company, using mining cash flows as a reinvestment engine, modeled on Berkshire Hathaway's insurance float.
- The model is unproven: XXI reported zero operating revenue and a $10.57 million operating loss in Q1 2026, the proposed Elektron deal has no definitive agreement, and any combination would be a related-party transaction given Tether's dual ownership.
Raphael Zagury was appointed CEO of Twenty One Capital (NYSE: XXI) effective July 20, 2026, succeeding Jack Mallers, who resigned to focus on Strike. Two days later, at Mining Disrupt 2026 in Miami, Zagury delivered a fireside chat titled "Here Be Dragons" and told the audience directly: the premium-funded equity-for-Bitcoin arbitrage that defined the sector's early innings cannot last.
The transcript of that session was filed with the SEC as an exhibit to an 8-K on July 24, 2026.
The Thesis He Walked In With
Zagury's core argument is straightforward. Issuing shares above net asset value and deploying the proceeds to buy more Bitcoin is a temporary market dislocation, not a permanent business model. As more companies replicate the strategy, the premium compresses. The spread closes. The free carry disappears.
His framing: mNAV multiples across the sector should trend toward 1x. That's not a prediction of collapse, it's a structural observation. Markets reprice arbitrage opportunities when the trade gets crowded. That is basic finance, and Zagury, who came up as a Managing Director at Deutsche Bank and Merrill Lynch and a Vice President at Goldman Sachs before co-founding one of Brazil's largest fintech lenders, knows the pattern.
The answer he's proposing is to build an actual operating business around the Bitcoin stack. The model he invoked is Berkshire Hathaway's insurance float: Berkshire writes insurance premiums, earns float, and deploys that capital into productive assets. Zagury wants Twenty One's Bitcoin mining operations, through a potential combination with Elektron Energy (which he founded), to serve the same function. The mining operation generates Bitcoin cash flow. That cash flow funds further accumulation and investment into Bitcoin-denominated businesses. The company measures performance in BTC terms, not dollars.
It's a more coherent framework than pure accumulation. Whether XXI can actually execute it is a separate question.
What the Balance Sheet Says Right Now
Twenty One held 43,514 BTC as of March 31, 2026, per its Q1 filing. It also posted zero operating revenue and a $10.57 million operating loss in the same period. The Berkshire analogy is aspirational; the float engine doesn't exist yet.
The proposed combination with Elektron remains under preliminary evaluation with no definitive agreement in place. Any deal would be a related-party transaction requiring review, given that Tether holds majority stakes in both entities. The original three-way merger proposed on April 29, 2026, at the Bitcoin 2026 conference in Las Vegas (Twenty One, Strike, and Elektron) is dead. Strike is staying independent. Mallers resigned, citing disagreement with the board over the company's direction, according to his public statement on X.
This context matters. Zagury's public warning about the mNAV trade dying could reflect genuine strategic conviction from someone who watched it play out from inside the sector. It could also be narrative management for a company navigating a messy leadership transition with no operating revenue and a stock well off its highs, shares fell nearly 18% on July 21 to around $4.37 on the day of the announcement. Both readings are compatible with the same set of facts.
For a broader look at how the bitcoin treasury sector is being stretched by imitators running increasingly thin playbooks, that dynamic is already visible. And the pressure on pure-accumulation models to justify their premiums over simply holding Bitcoin is getting harder to wave away, especially as Strategy's own metrics come under scrutiny for similar reasons.
What Has to Be True for Zagury to Be Right
The falsifiable version of Zagury's thesis: the mNAV premium-arbitrage era is structurally over, and companies that can't build real Bitcoin-denominated revenue will bleed toward NAV like any closed-end fund trading at a persistent premium eventually does.
The trigger that would disprove it: if mNAV multiples across the sector, XXI, Strategy, and the imitators, re-expand meaningfully above 2x in the next 12 months without corresponding operating revenue growth, the trade isn't dead. It paused. Watch the mNAV ratios, not the press releases.
If Zagury's framework works and the Elektron combination closes at reasonable terms, Twenty One becomes something genuinely different: a Bitcoin-native operating company using mining cash flows to compound a large BTC stack and invest in Bitcoin-denominated businesses. That is a more defensible model than perpetual equity issuance above NAV. It's also a harder model to build, and the related-party structure means every step will draw scrutiny.
The broader implication for the sector isn't subtle. If the largest Tether-backed Bitcoin treasury is publicly saying the easy money is gone, the companies further down the food chain, with smaller stacks, thinner margins, and no mining operations, face a harder road to justify their premiums. The corporate Bitcoin treasury wave isn't reversing, but it's stratifying. True operators will separate from paper-equity plays.
What to Watch
The preliminary Elektron combination is the key variable. If it closes, on what terms, at what valuation, and with what independent review of the related-party dynamics, will reveal whether Zagury's framework is real capital allocation or a restructuring story dressed up as strategy. A deal announcement, or the absence of one over the next two quarters, will answer the question the Miami chat left open.

Frequently Asked Questions
The three-way combination, proposed by Tether Investments on April 29, 2026, at the Bitcoin 2026 conference in Las Vegas, is off. Jack Mallers resigned as CEO and director of Twenty One effective July 20, 2026, citing disagreement with the board over the company's direction. Strike is remaining independent. A two-way combination between Twenty One and Elektron Energy remains under preliminary evaluation with no definitive agreement, but the original structure is dead.
Zagury's framing at Mining Disrupt suggests the goal is to outperform a passive hold, using mining cash flows and Bitcoin-denominated investments to compound the stack faster than simply holding. But he hedged: the company measures performance in BTC terms, and the model depends entirely on the Elektron combination closing and generating real operating cash flow. With zero operating revenue in Q1 2026, the outperformance case is forward-looking, not yet demonstrated.
