Copy Global index providers including S&P Dow Jones Indices and Nasdaq are reviewing rules to accelerate the inclusion of newly listed large-cap companies into benchmark indices. | Photo Credit: Brendan McDermid 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.
