The U.S. Senate Committee on Banking, Housing and Urban Affairs released a letter from Ranking Member Elizabeth Warren to S&P Dow Jones Indices, FTSE Russell, Morningstar Indexes and Nasdaq over reported index rule changes that could speed SpaceX’s inclusion in major stock indexes. The letter raises concerns that such changes could waive typical investor and market safeguards and lead index funds to buy large amounts of SpaceX stock automatically if the company is added after an initial public offering. Warren argued that index eligibility rules are intended to protect passive investors and preserve index credibility, and that altering them for large companies could create risks for investors, including retirees and others using index funds for savings. The letter cited reports that SpaceX lobbied for quicker index entry and warned that millions of index fund investors could be exposed to billions of dollars of SpaceX stock purchases without direct input. The index providers were asked to provide information on their decision-making process and plans for these investments by June 26.
