Paving the way for Musk's SpaceX to go public. The S&P 500 index company has officially adjusted its criteria for including ultra-large-cap companies in the index. Under the new plan, companies can be included in the index just 6 months after going public, compared to the previous requirement of 12 months. Additionally, the previous rule requiring at least 10% of shares to be held by retail investors has been removed, and companies are no longer required to have positive net profits. All these adjustments seem to be aimed at SpaceX, the rocket company founded and managed by Musk, which is planning to go public in the second half of this year. The policy is expected to take effect in June this year, meaning SpaceX could be included in the S&P 500 as early as 6 months after its IPO, potentially triggering tens of billions of dollars in index fund investor purchases.
