SpaceX's $100B Insider Lock-Up Expires — Stock Rises 6.1% Instead of Falling

SpaceX's post-IPO lock-up expired on August 6, 2026, releasing the first 20% tranche of eligible insider shares — up to 911.5 million shares worth an estimated $100 billion — for potential sale, more than doubling the stock's public float from about 4.9% to 11.8% of shares outstanding. Contrary to the conventional expectation that a large supply increase would pressure the price lower, SPCX shares closed up 6.1% on the day, after swinging between modest gains and losses of less than 3% in early trading, as the market judged the unlock as a step toward a more liquid, broadly tradable stock rather than a signal of insider exodus.
