SpaceX Is In. Depending On Which Index You Ask.

The S&P 500 said no. The Nasdaq 100 rewrote its rulebook. Passive funds are now on the clock.

SpaceX opened trading today on Nasdaq under ticker SPCX, priced at $135 per share and targeting a $1.75 trillion valuation — the largest IPO in stock market history, raising $75 billion across roughly 555.6 million shares. By midday, the stock had pushed past $170. Demand was never the question. The order book ran more than 3.5 times oversubscribed, pulling in over $250 billion in orders chasing a $75 billion raise.

What matters now isn’t the opening pop. It’s the two-track index story unfolding underneath it.

The S&P 500 Held The Line

On June 4 — eight days before SPCX began trading — S&P Dow Jones Indices announced it would not change the eligibility requirements for the S&P 500. All three contested rules remain fully intact: a 12-month seasoning period, four consecutive quarters of positive GAAP earnings, and a minimum 10% public float. The committee stated explicitly that exceptions to these requirements should not be granted solely based on market capitalization.

SpaceX clears exactly none of them. The company posted a $4.94 billion net loss in 2025, even as revenue grew 33% to $18.67 billion. Its current free float sits at roughly 3% to 4% — far below the 10% threshold. And it began trading today, meaning the 12-month clock only just started. The earliest realistic window for S&P 500 inclusion is now mid-2027, and only if SpaceX threads the profitability needle first. It has never posted a GAAP profit.

That delay is not trivial. Bloomberg Intelligence estimated SpaceX would have drawn approximately $14 billion in forced passive buying upon S&P inclusion alone. That money is now a 2027 event at the earliest — a known future overhang that institutional desks are already modeling as a second-wave catalyst.

The Nasdaq 100 Rewrote Its Rules

Nasdaq moved in the opposite direction. In March 2026, effective May 1, Nasdaq overhauled its Nasdaq-100 inclusion methodology. The new Fast Entry rule allows any newly listed company ranking in the top 40 by market cap to enter the index after just 15 trading days — down from a prior seasoning window of three months to a full year. The minimum float requirement was eliminated entirely. Low-float stocks now receive an adjusted weighting multiplier of up to 3x their prevailing float in certain scenarios.

SpaceX qualifies. Counting from today’s June 12 listing, the 15-trading-day window closes around July 1. The Invesco QQQ Trust, the largest Nasdaq-100 ETF with roughly $430 billion in assets, has no discretion over whether to buy SPCX — only over execution speed. Every fund benchmarked to the Nasdaq-100 must purchase shares of a stock still riding its post-listing move, with 15 days of trading history and a float of 3% to 5%.

Near-term estimates put mechanical buying at $22 to $27 billion across QQQ and Russell 1000 trackers combined. The Nasdaq-100 is tracked by more than 200 investment products with over $600 billion in assets globally. Goldman Sachs analysts estimated the Fast Entry rule change alone could trigger up to $60 billion in forced buying across the index.

A slight tangent worth noting: Nasdaq adopted these rule changes weeks before SpaceX filed its S-1 and chose Nasdaq as its listing venue. Reuters reported in March that SpaceX advisers had approached index providers to accelerate inclusion ahead of the IPO. Whether the timing was coincidental or not, the structural outcome is the same — passive funds are on the clock.

The Governance Layer Nobody Is Pricing

Musk holds approximately 42% of SpaceX’s equity through a dual-class share structure that grants him roughly 82% of voting control via Class B stock. Class B shares carry 10 votes each. Public investors buying Class A shares have no practical ability to remove Musk, block a transaction he supports, or override any decision he makes. SpaceX’s own S-1 acknowledges that public investors will not have the same protections afforded to shareholders of companies subject to all Nasdaq corporate governance requirements — because SpaceX is listing as a controlled company and has claimed the associated exemptions.

That structure is precisely what bars SpaceX from the S&P 500 via the float requirement, and it’s also why Morningstar’s analyst pegged fair value at approximately $780 billion — roughly 55% below the IPO price — citing the small public float, index-inclusion mechanics inflating demand, and unproven profitability.

The math at $135 per share: SpaceX priced at roughly 94x its 2025 revenue. No precedent exists among the world’s most valuable companies for that multiple at this revenue base. That is the bull case and the bear case occupying the same number simultaneously.
