Tether Proposes Twenty One Capital + Strike + Elektron Energy Three-Way Merger — XXI Pops 8%

Tether Investments has proposed a three-way merger combining Twenty One Capital (XXI) — the Bitcoin-treasury company chaired by Jack Mallers — with Mallers' payments company Strike and Bitcoin miner Elektron Energy. XXI shares popped roughly 8% on the news. The combined entity, if approved, would unite Bitcoin treasury, mining, payments, lending and capital-markets infrastructure under a single listed parent — and would arguably be the most concentrated public-market Bitcoin pure-play ever assembled.

What each leg brings to the merged entity

Twenty One Capital (XXI) is the bitcoin-treasury vehicle launched in 2025 by Tether, SoftBank and Mallers via a Cantor SPAC structure. As of recent disclosures, XXI holds 43,500+ BTC, with explicit guidance to grow that position via accretive issuance and operating cash flow. Strike, founded by Mallers, runs the consumer-facing Lightning-rail payments product that pioneered Bitcoin remittance at consumer scale and has been the highest-profile US Lightning brand. Elektron Energy, led by Raphael Zagury, is a Bitcoin miner managing approximately 5% of the current Bitcoin network's computing power with all-in production costs below $60,000 per bitcoin — a sub-cycle-average cost basis that becomes meaningful in any bear-market drawdown.

The strategic logic

Three things this merger does that the three components separately cannot. One: it creates a publicly-traded vehicle that investors can buy as a single proxy for the entire Bitcoin economy — treasury holdings (XXI), payments rail (Strike), and mining operations (Elektron) — eliminating the need for retail and institutional buyers to assemble three separate positions. Two: it lets the entity self-fund treasury accumulation through mining cash flow, Strike payment revenue, and capital-markets activity, reducing dependence on equity issuance. Three: it gives Tether a public-equity vehicle through which to route Bitcoin-related capital allocation without Tether itself having to go public — preserving Tether's private status while creating a listed expression of its Bitcoin thesis.

Leadership and structure

Per the proposal, Mallers would continue as CEO of the combined entity, with Elektron's Zagury as President — pairing Mallers' product and consumer-facing leadership with Zagury's mining and capital-markets expertise. No deal terms (exchange ratios, premium, structure) or timeline have been disclosed publicly. The merger requires shareholder approval at each leg and, given Tether's controlling positions across all three entities, will face scrutiny over related-party transaction fairness — a standard issue in any controlling-shareholder-initiated merger.

What to Watch

Three signals over the next 60 days. Independent valuation work: the fairness opinions for each leg of the merger will be the first substantive disclosure of how the deal is being structured economically. Expect either Houlihan Lokey, Lazard, or a similar special-committee advisor to be retained at each entity. SEC filing posture: a Tether-controlled three-way merger of two private (Strike, Elektron) and one public (XXI) entity into a publicly listed combined parent will require substantial S-4 or proxy filings, and the disclosures inside those filings will materially shape the institutional perception of Tether's broader balance sheet for the first time. Shareholder reaction at XXI: the 8% pop is a starting reaction, not a final verdict — minority XXI shareholders will need to be persuaded that the merger ratio doesn't transfer value disproportionately to Tether. Watch for activist or institutional shareholder commentary in the next two weeks.
