Nasdaq is accelerating big tech entry with fast-track rules.

Nasdaq is accelerating big tech entry with fast-track rules. The exchange is overhauling its Nasdaq-100 index to allow newly listed large-cap companies to join within weeks instead of waiting over a year. This reflects a structural shift where firms now go public as fully mature entities rather than early-stage growth stories. The new framework takes effect May 1, with impact visible from June. Companies will be assessed on market capitalization within their first trading week and fast-tracked if they rank among top constituents. Nasdaq is also updating how it calculates market cap to include unlisted share classes, capturing the true scale of modern corporations with complex structures. The move addresses a long-term decline in publicly listed US firms, which has fallen by more than a third since 2000, raising concerns about market depth and diversity.
