BTC Writedown Sends Twenty One Capital to $414M Q2 Loss

Twenty One Capital (XXI) booked a $413.5 million net loss in the second quarter, of which $401.5 million came from mark-to-market declines on its 43,514 BTC holdings, worth roughly $2.78 billion at current prices. The NYSE-listed firm holds the second-largest publicly traded bitcoin treasury, just ahead of Japan-based Metaplanet at roughly 43,000 BTC, and ended the quarter with $106.1 million in cash and $484.5 million of convertible notes outstanding. XXI rose about 1% to $4.62 in early trading Tuesday but remains down nearly 50% year-to-date.

Why it matters

The quarter lands roughly three weeks after Raphael Zagury replaced founder Jack Mallers as CEO, with Mallers returning full-time to bitcoin payments firm Strike. Strike also pulled out of a proposed merger with Twenty One, leaving a potential acquisition of Zagury's bitcoin miner Elektron Energy under consideration.

In his first shareholder letter, Zagury framed the company as needing to evolve past pure treasury status, outlining five priorities covering governance, building or buying operating businesses, developing capital-market capabilities, an M&A operation, and a future bitcoin lending and credit business. He pointed to Berkshire Hathaway as the long-term blueprint and acknowledged the stock's structural discount, with XXI's mNAV sitting at roughly 0.7x the value of its bitcoin holdings.

Market impact

The mNAV gap between XXI's share price and its BTC stack is the central question for the stock going forward. Strategy still trades at a premium and anchors the sector, while XXI's 0.7x multiple shows the market is pricing in the operational risk of running a leveraged bitcoin balance sheet against the backdrop of convertibles coming due. Metaplanet's parallel accumulation at roughly 43,000 BTC means XXI can no longer claim comfortable second place by float alone, so the contest for sector rank now runs through both balance-sheet growth and operating execution. Whether Zagury's Berkshire-style buildout narrows that discount, or simply layers execution risk on top of an already-writedown quarter, is the question the next four reporting periods will answer.
