what happened
According to Moody's, Elon Musk is pushing a tie-up of Tesla and SpaceX that could serve as a backdoor into the S&P 500 index. SpaceX was earlier denied a swift entry into the index. The combined company is estimated at nearly $3.5 trillion and would rank among the five biggest S&P 500 stocks.
TD Securities' Reid Noch estimates that inclusion could generate about $100 billion of demand from index funds, which manage roughly $16 trillion. If the shares do not make it into the index, passive funds would have to sell their holdings. People familiar with the matter said an announcement could come as soon as next month.
why it matters
The deal matters beyond the companies themselves, since it could raise the weight of tech stocks in the S&P 500. Analysts warn that the index is becoming more concentrated and more tied to AI expectations. Tesla trades at more than 180 times expected earnings versus 18 for the index, so valuations remain stretched.
