New Nasdaq Index Rules Are a Gift for IPO Flippers. Here’s Why.

Nasdaq will change Nasdaq-100 membership rules effective May 1 to allow large IPOs to enter the US Tech 100 just 15 days after listing and to waive the 10% free-float requirement. Nasdaq will apply a temporary three-times multiplier to a low initial float when calculating index weight. Analysts warn the fast-track and extra weighting could create a supply-demand imbalance and predictable price spikes on day 15 as index funds and trackers buy newly included shares, potentially enriching issuers and “flippers.” Researchers estimate fast-tracking can let issuers raise ~6% more capital. Nasdaq argues the adjustment is conservative and that index buying wouldn’t overwhelm float (citing examples showing modest percentage impacts). The move increases Nasdaq’s edge vs. NYSE in competing for mega-listings (SpaceX, OpenAI, Anthropic) and has prompted S&P to consider similar changes.
