Index Providers Speed $1.77 Trillion SpaceX IPO Entry, Pulling 401(k)s In Faster

3 articles · Updated · Fortune · Jun 4

$1.77 trillion SpaceX and nearly $1 trillion Anthropic are driving index providers to shorten or drop waiting periods, allowing major IPOs into benchmark indexes far sooner than before.
FTSE Russell now allows fast entry after as few as five trading days, Nasdaq after 15, and S&P Dow Jones is reportedly weighing similar changes.
Index funds tracking those benchmarks may have to buy the shares shortly after listing, giving retirement savers exposure whether they actively choose it or not.
Critics say the old guardrails were created after the dot-com crash to keep unseasoned or unproven companies out; Tesla waited about 10 years before joining the S&P 500.
Anthropic confidentially filed for an IPO on Monday after a valuation of $965 billion, while SpaceX began its roadshow this week, making their scale a test of how indexes balance market demand and saver protection.
