Jack Mallers' Twenty One Capital Reveals Ambitious Bitcoin Accumulation Plans

After months of silence and building in the background, Twenty One Capital (XXI) has finally laid out its vision for becoming what CEO Jack Mallers calls the "dream Bitcoin company." In a sweeping announcement on April 29, Tether Investments — XXI's largest shareholder — proposed a bold three-way merger that would unite the Bitcoin treasury firm with Mallers' payments platform Strike and Tether's Bitcoin mining operation Elektron Energy. The market responded enthusiastically, with XXI shares climbing nearly 8% in after-hours trading.

Currently holding 43,514 BTC making them the second-largest public corporate Bitcoin holder in the world, XXI is set to grow its treasury significantly if the proposed mergers go through. Strike, which Mallers also leads as founder and CEO, holds at least 1,500 BTC on its balance sheet, meaning the combined entity would instantly add to an already formidable war chest.

The proposal would transform XXI from a pure treasury vehicle into a fully integrated Bitcoin platform spanning mining, financial services, lending, payments in over 100 countries, and capital markets — all under one publicly traded roof. Mallers endorsed the plan, calling it "a great idea." Tether has also recommended that Elektron founder and CEO Raphael Zagury serve as President of the combined entity — pairing his capital markets and mining execution experience with Mallers' product vision and consumer brand.

Mallers is adamant that XXI is not a Bitcoin treasury company in the mold of Michael Saylor's Strategy. He wants to be judged on operating income and cash flow, not just BTC per share. His critique of the current landscape is pointed:

"On one side of the spectrum you have extremely successful businesses that have no conviction in Bitcoin at all."

And on the other end:

"You have extremely convicted businesses in Bitcoin and they never sell and they want to stack all the Bitcoin they can — but they don't necessarily focus on building."

He is careful to note that this is not a shot at Saylor, who he called a "tremendous success story" for the space. Rather, Mallers wants XXI to occupy a different quadrant entirely — high Bitcoin conviction and high operating income. The company, he argues, should be a builder, not just a holder, the cash flow engine is central to Mallers' thesis.

Tether's Bitcoin mining arm, Elektron Energy, is one of the largest private miners in the world, managing approximately 50 EH/s — roughly 5% of the entire Bitcoin network's hashrate. Crucially, Elektron's all-in production cost per Bitcoin currently sits below $60,000, meaning at today's prices of around $75,000, every coin mined is immediately profitable. However, Elektron is not without controversy. The company is at the center of a lawsuit filed by Swan Bitcoin, whose CEO Cory Klippsten alleged that Tether effectively "stole" Swan's Bitcoin mining business. According to Swan's legal complaint, several senior executives resigned in a coordinated manner in August 2024 before immediately forming a new entity — Proton Management — to take over management of Swan and Tether's joint mining venture, 2040 Energy. Swan alleged that Tether "procured" the mass resignations and "engaged in a conspiracy" with the departing employees. Notably, Raphael Zagury — now proposed as XXI's President — was identified in Swan's complaint as Swan's former Chief Investment Officer prior to his "abrupt and coordinated resignation." The litigation is ongoing.

The idea is for XXI to issue its own preferred stock or convertible bonds — similar in concept to Strategy's STRC — but with a key distinction: rather than relying on external capital raises, XXI would fund issuances through its Bitcoin treasury and operating cash flow.The structured products roadmap goes even further. Mallers envisions securitising mining revenue streams and loan books, building fixed income products backed by Bitcoin, and using the company's balance sheet to originate debt against the network itself:

"We can securitize our loan book, can securitize our mining revenue. We can build structured products, fixed income products and bonds, can have Bitcoin-backed debt."

Perhaps most ambitiously, Mallers outlined a strategy to acquire other profitable Bitcoin companies and fold them into the XXI umbrella — compounding cash flows, growing network effects, and scaling what he describes as a "Bitcoin machine." He was effusive about the quality of builders already in the space:

"There are so many good Bitcoin companies out there... This space is full of unbelievable builders that are convicted along the same vision that I am. And we can compound other companies' cash flows, compound the valuable assets that other businesses have that will grow our network effect, grow our economies of scale, and really grow this Bitcoin machine."

The ambition is to build something Mallers calls "the ideal Bitcoin company" — one deploying leverage, capital markets access, and operating income alike in pursuit of maximum Bitcoin accumulation:

"In my opinion, this to me is the ideal Bitcoin company. It's the dream Bitcoin company. And that's what Tether and I are really aligned in proposing and executing as the future of Twenty One." Transaction terms, timelines, and governance details have not yet been disclosed, with Tether saying further information will follow as discussions progress. The proposal is subject to shareholder approval, but given Tether's huge stake and Mallers' endorsement, the mergers are considered highly likely to proceed. If consummated, Twenty One Capital would emerge as something genuinely new in public markets: a Bitcoin-native conglomerate with the treasury depth of a reserve vehicle, the cash flow of a payments business, the hash power of one of the world's largest miners, and the capital markets infrastructure to keep accumulating Bitcoin — indefinitely.
