Some Indexes Accelerate Entry for Massive IPOs

FTSE Russell: FTSE Russell announced the results of its index consultation on May 26, 2026, with changes effective as of the same date. Russell’s U.S. Equity indexes will now allow fast entry for very large IPOs on the fifth trading day, instead of waiting for the next quarterly rebalance. However, the weight of the IPO in the index will be based on investable market capitalization. In other words, only shares available to public investors will be considered when calculating the company’s size. Plus, IPOs must have at least 5% of shares available to public investors, either on the IPO date or within the next 12 months.

Uh. So does that 5% count towards the minimum float amount that triggers automatic buying by some index funds?
