Nasdaq updated its rules to allow large initial public offerings rapid entry into the Nasdaq-100 index. The new Fast Entry mechanism takes effect on May 1, 2026.

Newly listed companies will undergo evaluation for inclusion after seven trading days. Eligible firms may join the index within 15 days, a significant reduction from the previous three-month minimum.

Market analysts view the move as a structural accommodation for a potential SpaceX IPO. SpaceX is reportedly considering a Nasdaq listing and negotiating for rapid post-IPO inclusion.

To qualify, a company's market capitalization must rank within the top 40 of current Nasdaq-100 members. Nasdaq designed the change to better reflect the market by capturing highly-valued companies that remain private for longer periods.
