Nasdaq has announced the implementation of a fast-track entry mechanism allowing recently listed companies to join the Nasdaq 100 more quickly. Moving forward, a company can be evaluated as early as its seventh day of trading and, if it ranks amongst the top 40 largest eligible market capitalizations, join the index by the fifteenth day. This reform, effective May 1, aims to reduce delays that previously could last up to a year.

This shift comes amid a changing market landscape, characterized by a decline in the number of US  listed companies and the rise of technology firms remaining private for longer periods. Some reach high valuations before their IPOs (such as SpaceX, OpenAI, or Anthropic), prompting index providers to adapt their rules to better reflect market reality and integrate these new players more rapidly.

Nasdaq also plans further adjustments, including a revision of capitalization calculations to include certain unlisted shares, the removal of the 10% minimum free-float threshold, and new exclusion rules for low-weight securities. Access to the Nasdaq 100 remains strategic for companies due to the significant capital flows linked to index funds, and other indices may follow suit in adapting.
