SpaceX Bitcoin Hoard Harvard ETF Cuts and a Bold Reserve Bill Reshape Crypto

The biggest corporate Bitcoin disclosure of the year landed this week when SpaceX filed its S-1 registration statement with the SEC ahead of a planned June 12 Nasdaq listing under the ticker SPCX. The filing confirmed that as of March 31, 2026, the aerospace giant held 18,712 BTC with a fair market value of approximately $1.29B, against a historical cost of $661M at an average purchase price of roughly $35,324 per coin. The revelation places SpaceX among the top corporate Bitcoin holders globally, sitting behind Strategy's 843,738 BTC and ahead of sister company Tesla's 11,509 BTC.

For Bitcoin watchers, Bitcoin Magazine called the S-1 the most significant corporate disclosure of 2026, noting that SpaceX will join Tesla on the short roster of public companies that treat Bitcoin as a balance-sheet asset once it lists. Analysts flagged that the IPO, which could be the largest in capital markets history at a projected $1.75T valuation, may trigger meaningful capital rotation across financial markets, adding a new dimension to how institutional investors price Bitcoin exposure inside a diversified tech conglomerate.

Harvard Trims Bitcoin ETF Stake While Congress Pushes Reserve Legislation

On the institutional investor front, Harvard Management Company drew attention after SEC filings showed the university's endowment slashed its BlackRock Bitcoin ETF position by roughly 43% in Q1 2026 and fully exited its Ethereum ETF stake entirely. The move stands in contrast to the broader narrative of growing institutional accumulation and signals that even well-resourced endowments are actively rebalancing crypto exposure as macroeconomic pressures and ETF outflows weigh on near-term sentiment. Bitcoin has faced headwinds in recent weeks, consolidating near $77K as hot inflation data, leveraged long liquidations, and geopolitical uncertainty continue to pressure price action.

Meanwhile in Washington, U.S. lawmakers introduced a new Strategic Bitcoin Reserve bill seeking to codify a federal BTC treasury targeting a $25B stash, according to reporting aggregated by CryptoSlate. The legislation, referred to in some circles as the American Reserve of Money Act, aims to establish long-term sovereign demand for Bitcoin and follows the White House's earlier pledge to detail the legal and operational structure for a government reserve within weeks. The bill arrives as the broader CLARITY Act, which defines how digital assets are treated under federal securities and commodities law, continues to advance through Congress, improving long-term regulatory sentiment even as short-term market volatility persists.
