You seem to be confused about how index funds work. Hypothetically even if $SPCX was added to the S&P500, funds that track that index wouldn't be legally required to purchase it at the IPO price. Have you ever even read a fund prospectus or do you believe the uninformed nonsense you read online? The way it actually works is that when a stock is added to an index the index funds gradually build a position using a series of trades over time.
