The stock opened at $150 — an 11% pop — and closed the first day at $160.95, up 19% . By mid-June, shares traded in the $201–$213 range, giving the company a market capitalization estimated between $2.6 trillion and $3 trillion . The IPO valued the company at roughly $1.77 trillion at the offer price, expanding past $2.1 trillion on the first trading day .

Note on the $2.4 trillion figure: No source in the available evidence cites exactly $2.4 trillion as a market cap. The $2.4 trillion figure may be an intermediate analyst estimate not confirmed in the search results.

FTSE All-World Inclusion in 10 Days

FTSE Russell confirmed that SpaceX was added to the FTSE Global Equity Index Series (GEIS), including the FTSE All-World and FTSE World indexes, effective June 22, 2026 — just 10 days after the June 12 IPO . This was made possible by a fast-entry rule change FTSE Russell adopted on May 26, 2026, weeks before the IPO, allowing newly listed mega-cap companies with investable market capitalizations above the Russell Top 500 cutoff to be added after as few as five trading days .

Additional Index Inclusions

• Russell 1000, Russell Top 200, Russell Top 50: FTSE Russell's formal index notice confirmed SpaceX for these indexes under the fast-entry rules, effective after the market close on June 26, 2026 (added to the indexes as of June 29) . Multiple sources confirm Russell 1000, Russell Top 200, and Russell Top 50 inclusion .
• MSCI Standard and Large-Cap Indexes: MSCI confirmed on June 8 that it would apply its existing early-inclusion rules for large IPOs, and on June 12 announced SpaceX would be added to its standard and large-cap indexes effective June 29, 2026 . MSCI's rules have been in place since 2007 and were not newly created for SpaceX — the company simply met the existing criteria .
• S&P 500 — blocked for now: S&P Global announced it would retain its profitability and seasoning requirements, effectively ruling out swift S&P 500 inclusion for SpaceX . The company must meet a minimum 12-month exchange listing and demonstrate GAAP profitability before it can be considered.
• Nasdaq-100: SpaceX was expected to be added after 15 trading days, with potential inclusion around July 6, 2026, following Nasdaq's own fast-entry rule change adopted on May 1, 2026 .
• CRSP and S&P Total Market Indexes: These indexes also added SpaceX as early as June 18, 2026, under their fast-track policies .

The $63 to $401 Valuation War

As of mid-to-late June 2026, the spread across analyst targets was extreme, reflecting fundamental disagreement about what SpaceX actually is:

Wall Street consensus average sits roughly between $164 and $185, a level the stock had already traded above by mid-June . KeyBanc Capital Markets declined to issue a specific target but estimated SpaceX's enterprise value at approximately $1.02 trillion in a base-case scenario — less than half its then-current valuation — suggesting the stock already reflects much of its anticipated growth .

Why Such a Wide Range?

The spread from $63 to $401 reflects a fundamental disagreement about how to categorize SpaceX. Morningstar and other bears value the company as an infrastructure and defense contractor with a finite addressable market, while Arete Research and other bulls value it as a dominant AI and space-economy platform with massive expansion potential tied to Cursor, Starlink, and enterprise AI .

The disagreement matters because passive index funds are now forced to buy regardless of valuation: with inclusion in the FTSE All-World, Russell 1000, MSCI World, and other major benchmarks, billions in passive capital will flow into SpaceX shares on schedule — but at prices the analyst community cannot agree on.

The Bigger Picture: Index Rules Changed for SpaceX

SpaceX did not just break IPO records; it forced structural changes to how indexes work. FTSE Russell adopted its fast-entry rule on May 26 explicitly for mega-cap IPOs . Nasdaq rewrote its index rules on May 1 . MSCI confirmed it would apply its existing early-inclusion rules . S&P Global was the only major provider that refused to bend, keeping its 12-month seasoning and profitability requirements intact .

This means index fund investors will gain exposure to SpaceX within weeks of its IPO — through the FTSE All-World (June 22), Russell indexes (June 29), MSCI indexes (June 29), and Nasdaq-100 (early July) — whether the stock is worth $63 or $401 per share.
