Why? An index fund represents the market (usually top 100 or 500 companies), and SpaceX will certainly be in the top few companies. I would argue it's a lot riskier to buy it after the IPO price (if you're buying it secondary it would be easier to spike prices by accident), plus then it's not representative of the actual market until you've purchased the stock.
Unless I'm misunderstanding this, buying at the sale price is the least risky way of purchasing the stock, which is what index funds should do. They should pursue the least risky way of indexing the market
