Nasdaq has announced significant changes to its listing requirements, effective May 1, 2026. The exchange will eliminate the 10% minimum float requirement and introduce a "Fast Entry" rule. This new rule allows mega-cap IPOs to be included in the Nasdaq 100 index approximately 15 trading days after their debut. These changes aim to streamline the process for large companies seeking rapid inclusion in the prestigious index, potentially increasing their visibility and attractiveness to investors.
