You can ignore AI giants like SpaceX, but your 401(k) won’t

NEW YORK (AP) — Think you can ignore all the hubbub around SpaceX, Elon Musk and IPOs? Your 401(k) won’t. Following its debut on Wall Street last month, Musk’s rocket company is worth a total of $2.1 trillion. That makes it worth roughly the same as Walmart, Exxon Mobil, Bank of America and IBM combined. And by virtue of having that big a value, SpaceX will soon join some high-profile stock indexes, including the Nasdaq 100 on Tuesday (July 8, 2026). That matters for investors and their 401(k) accounts because they’re depending more than ever on funds that simply mimic such indexes.
