SpaceX IPO Situation Is Crazy

Why It Matters

Faster index inclusion and large retail allocations can materially lift the IPO’s initial price and liquidity, meaning index-trackers and everyday investors could provide significant mechanical support to SpaceX’s market value—and set precedents that will affect passive investing and future large listings.

Summary

SpaceX’s planned IPO has prompted major index providers and brokerages to revamp longstanding rules so the company can be added to large-cap indices and attract heavy retail demand. NASDAQ and some others adopted faster inclusion and relaxed free-float requirements—allowing companies that rank in the top market-cap tier to be added after roughly two weeks and permitting much lower free floats—while S&P kept its 12-month waiting rule. SpaceX is also targeting an unusually large retail allocation (around 30%) and brokerages are promoting direct participation, making the deal likely to be oversubscribed. Together, these changes boost near-term buying pressure from index funds and retail investors and reshape how future mega-IPOs will be handled.

Original Description

There are two things people keep asking me about the SpaceX IPO: will it get added to their index funds, and—if given the opportunity—should they invest directly in the SpaceX IPO?
Many of the major indices have made changes to their rules recently, and it has a lot of people confused about what’s actually going to happen when SpaceX goes public. If keeping up with all of these changes has you a little confused about what this all could mean for your portfolio, this video is for you.
