SpaceX IPO Could Create 'The Biggest Short Squeeze' of All Time on Index Funds. Here's How That Happens.

SpaceX's IPO could create the biggest short squeeze on index funds due to its low float-adjusted ranking and 366-day lock-up on founder shares. Index funds must buy shares upon inclusion, but there isn't enough stock to meet demand. This scenario was outlined by Bloomberg columnist Matt Levine. The IPO targets a $1.75 to $1.8 trillion valuation. Float-adjusted rules rank SpaceX 195th in the S&P 500.
