SpaceX shares closed Wednesday at $150.88, up 5.15% from $143.49, before rising 2.6% to $154.81 Thursday, as the company’s market capitalization approached $2 trillion. Its Nasdaq-100 weighting is set to increase from approximately 1.28% to roughly 2.82% after Friday’s close, effective September 21, potentially generating $15.5 billion to $22 billion in mandatory passive purchases from funds tracking about $1.7 trillion in index assets. Investors are also watching Starship Flight 14, targeted for Sept. 22 as the vehicle’s first fully orbital attempt and first planned deployment of third-generation Starlink satellites, alongside more than 2.3 billion restricted shares scheduled for release in late October and mid-November. SpaceX reported second-quarter 2026 revenue of $7.81 billion, up 91.9% year over year, and an EPS loss of $0.09 versus an expected loss of $0.26. The stock remains volatile, and index buying does not guarantee gains, as shares fell almost 6% during the company’s July 7 Nasdaq-100 inclusion despite approximately $4.3 billion in mandated passive buying.
