What History Says About Stocks That Join the Nasdaq-100 and What It Means for SpaceX

SpaceX was added to the Nasdaq-100 on July 7, 2026, and initially dropped 17% in its first 10 days, following historical patterns where most new index additions decline in their first week. However, historical data shows stocks added to the Nasdaq-100 typically gain 3.6% after one month and 6.3% after three months. SpaceX's long-term prospects depend on capturing its $26.5 trillion addressable market in AI infrastructure, with potential revenue from computing capacity deals with Alphabet, Anthropic, and the Department of Defense, though the company faces significant capital expenditure requirements and already substantial losses.
