S&P Dow Jones Indices considers new index rules as mega IPOs loom

April 30 (Reuters) – S&P Dow Jones Indices said on Thursday it has kicked off a consultation that could result in major changes to rules governing the entry of companies into its indexes such as the S&P ​500.

As high-profile names such as Elon Musk’s rocket maker ​SpaceX and AI heavyweights Anthropic and OpenAI prepare to go public, index operators are racing to address the long waiting time for newly listed large-cap companies to join flagship equity benchmarks.

Here are some details:

• S&P DJI is considering reducing the time a company needs to be public before being eligible for index inclusion to six months from 12 months.

• It is also mulling excluding the profitability requirements for large-cap companies.

• “These megacap companies may pose unique challenges for index methodologies within the relevant index families, which were originally designed for more conventional listing profiles,” S&P DJI said.

• Exchange heavyweight Nasdaq last month unveiled a new set of rules to speed up the entry of newly listed large-cap companies to its flagship equity benchmark Nasdaq-100.

• Other indexes such as the FTSE Russell are also racing to overhaul the rules governing their benchmark indexes.

• S&P’s market consultation is open until May 28, with potential changes, if adopted, likely to be tentatively implemented on June 8.
