SpaceX Goes Public: SPCX Begins Trading Today in a Record $75 Billion IPO

The Largest IPO in History Prices at $135

SpaceX priced its initial public offering after the June 11 close: 555,555,555 shares at $135 apiece, raising roughly $75 billion at a valuation near $1.77 trillion. Underwriters hold an option for an additional 83.3 million shares. The stock begins trading Friday, June 12, on the Nasdaq under the ticker SPCX.

At ~$75 billion raised, the listing more than doubles the previous record — Saudi Aramco's $29.4 billion debut in 2019 — making it the biggest IPO ever by proceeds.

The Real Story: An Index Reshuffling, Not Just a Listing

For most retail portfolios, the headline number matters less than where SpaceX lands in the major indexes — because index membership forces passive funds to buy.

The two big benchmarks split on the question:

• Nasdaq-100 — fast-tracked. Under a revised methodology effective May 1, 2026, any newly listed company ranked among the top 40 by market cap can enter the Nasdaq-100 after just 15 trading days. At a $1.77 trillion valuation, SpaceX clears that bar easily and is on track for fast inclusion.
• S&P 500 — declined. S&P Global kept its existing rule requiring positive GAAP earnings in the most recent quarter and across the trailing four quarters. SpaceX does not yet qualify, so it stays out of the S&P 500 for now.

The practical effect: a name this large entering the Nasdaq-100 triggers mechanical buying from every fund that tracks it.

What It Means If You Own QQQ or a Nasdaq-100 Fund

If you hold the Invesco QQQ Trust (QQQ) or any Nasdaq-100 index fund, you don't have to buy SPCX directly to get exposure — those funds will be required to add it once inclusion takes effect, roughly 15 trading days after the debut. That is the "portfolio reshuffling" being discussed: passive Nasdaq-100 money rotating to make room for one of the largest additions the index has ever absorbed in a single step.

S&P 500 index-fund holders (SPY, VOO) get no automatic exposure until SpaceX meets the profitability test — which may be a long way off.

What to Watch on Day One

First-day IPO tape is its own animal: a single opening cross, a wide range, and volume that won't resemble a normal session. A few things worth tracking rather than predicting:

• The opening print vs. the $135 offer price — where supply and demand actually clear.
• First-session volume — how much real float is changing hands on day one.
• The intraday range — first-day volatility on a name this size sets the early reference levels.

You can follow SPCX's price, volume, and intraday chart live on its Tapeboard chart page, and screen the day's biggest movers — IPO or otherwise — on the scanner.
