The IPO opened 11% higher, now near 30% up; 300 million shares traded, float is 555 million; no major plumbing issues unlike some past IPOs.
Contrasts with Facebook's 2012 IPO which opened 11% but finished flat, suggesting SpaceX's debut is more robust. Notes the unusual lockup: Elon Musk's 6.4 billion shares locked for a full year, others staggered, with 20% of existing shares free after Q4 2026 earnings.
