The market distortion from an IPO's index inclusion isn't a one-time event. As insiders' shares unlock months later, the public float increases. Nasdaq's rules will then force index funds to buy even more shares to match the new, higher float (multiplied by 3x), creating a recurring cycle of predictable, forced buying and price distortion.

The primary driver for institutional investors in the SpaceX IPO isn't the company's valuation but the "relative return" risk. The fear of underperforming peers who buy in is a more powerful motivator than the fear of the stock being overvalued, creating intense buying pressure.

SpaceX arranged to be included in major indices like the NASDAQ 100 in just 15 days, versus the standard 90-day cooling-off period. This forces passive index funds to buy shares amidst peak hype, creating artificial demand and sidestepping normal price discovery mechanisms.

For companies like SpaceX, Nasdaq now allows index inclusion in just 15 days (down from six months) and artificially inflates weight by treating a 5% float as 15%. This creates a massive, predictable, and forced buying event from index funds, which must sell other holdings to accommodate the new stock, distorting the market.

NASDAQ altered its rules to allow SpaceX early entry into the NASDAQ 100 index, just 15 days post-IPO. This forces index funds to purchase billions of dollars worth of stock on a specific date, creating a predictable, short-term demand spike for early investors regardless of the company's long-term fundamentals.

By offering only a small fraction of its shares ($75B out of a trillion-dollar valuation), SpaceX is creating a supply-demand imbalance. This classic IPO strategy forces index funds and institutional investors to buy into a potential price bubble, risking significant losses when more shares eventually hit the market.

The pressure for SpaceX to join major indices like the S&P 500 recalls a dangerous historical precedent. In the 2000s, overvalued financial firms were added to the Dow at the market's peak, just before the financial crisis. Adding a risky, unprofitable giant like SpaceX could similarly signal a market top and introduce systemic risk.

For trillion-dollar private companies like SpaceX going public, the traditional 90-180 day lockup period is inadequate. The massive volume of insider shares hitting the market at once could crash the stock. Investment bankers are now designing staggered lockup releases to manage this unprecedented liquidity event.

Index providers are including massive IPOs like SpaceX into benchmarks within days of listing. This forces passive index funds, which hold vast amounts of retirement savings, to automatically buy these shares while they are still highly volatile, exposing everyday savers to the risk of buying at an improper price.
