The SpaceX IPO means index funds will be legally required to hand Elon Musk your retirement money. Passive investing needs more scrutiny.

SpaceX is targeting up to a 1.75 trillion dollar IPO valuation, larger than 95% of current S&P 500 companies before it's even public, and the moment it lists and hits inclusion criteria it becomes a top-10 S&P constituent by market cap, possibly top-5 depending on opening price action.

Every index fund on earth, your Vanguard three-fund portfolio, your target-date retirement account, your 401k you've never looked at, is contractually required to buy SpaceX shares proportional to its index weight with no vote, no opt-out, and no requirement that anyone actually underwrote the fundamentals at 68x sales. We're talking hundreds of billions in forced passive buying from vehicles that exist specifically to remove human judgment from capital allocation, which works great until the thing being allocated into is the largest IPO in human history run by someone with active control over the federal agencies that regulate and contract with it.

That last part is the piece that doesn't get enough attention. SpaceX holds dominant government launch positions, just absorbed xAI to compete directly in AI infrastructure, and its CEO is currently restructuring the regulatory and contracting apparatus that governs its own competitive environment. The mandatory passive buying wave will fund expansion into markets where SpaceX competes against other companies those same index funds also own, except one competitor here has a relationship with the referee that is not available to the other competitors.
