SpaceX is planning to go public on the Nasdaq around June 12, 2026, targeting a valuation between $1.75 trillion and $2 trillion. If you own a broad market index fund, you may end up holding shares whether you wanted to or not.

That is because major index providers, including Nasdaq and S&P Dow Jones Indices, have relaxed their standard inclusion requirements specifically to accommodate SpaceX’s listing. The result: the company’s stock could be added to major benchmarks as soon as five trading days after it starts trading, skipping the usual profitability and seasoning periods that typically keep freshly public companies out of passive portfolios.

How SpaceX lands in your portfolio

Most people don’t pick individual stocks anymore. They buy index funds, those pre-packaged baskets that track benchmarks like the S&P 500 or Nasdaq 100. When a new company gets added to those benchmarks, every fund tracking them has to buy shares. It’s automatic.

ETFs likely to include SpaceX after listing include some of the most widely held funds in existence: VOO (Vanguard S&P 500), QQQ (Invesco Nasdaq 100), IWB (iShares Russell 1000), and VTI (Vanguard Total Stock Market). Collectively, these funds manage trillions of dollars and sit inside millions of retirement accounts.

The estimated weight of SpaceX in these benchmarks would be modest, roughly 0.08% to 0.14%. That might sound trivial, but at the scale of passive investing, even a fraction of a percent translates to billions of dollars in mandatory buying.

The IPO math and the float problem

SpaceX aims to raise approximately $75 billion in the offering, and institutional appetite appears robust, with over $10 billion in orders already placed. The company would enter public markets as the largest IPO in history by a wide margin.

SpaceX is expected to have a very low public float, with only an estimated 3-4% of shares available for trading. When every S&P 500 tracker in the world needs to buy SpaceX shares within days of listing, and there aren’t that many shares to go around, price dynamics can get unpredictable. It’s the same mechanic that made Tesla’s index inclusion in December 2020 such a volatile event, except SpaceX’s float would be even thinner relative to its market cap.

Seasoning requirements exist for a reason. They give the market time to establish a company’s trading patterns and let early volatility settle before dumping shares into passive portfolios that grandparents and pension funds depend on. Bypassing those guardrails for a $2 trillion company suggests the index providers see more risk in excluding SpaceX than in including it early.

What this means for crypto investors

SpaceX currently holds approximately 8,285 BTC in its corporate treasury, making it one of the larger public-company Bitcoin holders once it lists. That treasury position creates a tangible link between the company’s stock performance and Bitcoin’s price trajectory.

Coinbase has already launched pre-IPO perpetual futures on SpaceX, letting crypto-native traders take positions on the stock before it even begins trading publicly.

With approximately $22 billion in retail allocation expected from the IPO, that capital has to come from somewhere. When a deal this large soaks up retail investment dollars, other risk assets, Bitcoin included, can experience short-term outflows.
