Twenty One Capital (NYSE: XXI) officially joined the New York Stock Exchange following its merger with Cantor Equity Partners, expanding a Bitcoin treasury that now exceeds 43,000 BTC and approaches a $4 billion valuation. The move makes XXI one of the world’s largest publicly traded Bitcoin holding companies, underscoring the scaling of institutional-linked crypto treasuries. On its first trading day, the stock hovered near $11, trading below Cantor’s pre-merger close around $14.

Investors noted that the initial pricing followed a familiar pattern for Bitcoin-treasury IPOs, with a premium that narrowed as the market digested the asset-heavy model. The company has drawn minor investments from Tether, Bitfinex, and SoftBank, according to disclosures. Management said the focus will shift toward building Bitcoin-centric financial infrastructure and educational products, signaling an evolution from an asset-driven balance sheet to a diversified operating model—pending market validation of the new business plan.
