TL;DR
| Detail | Value |
|---|---|
| Ticker | SPCX |
| Exchange | Nasdaq |
| Pricing | $135/share fixed |
| Pricing date | June 11, 2026 (after market close) |
| First trading day | June 12, 2026 |
| Total raise | ~$75 billion |
| Valuation | ~$1.77 trillion |
| Oversubscription | ~3.3x ($250B in orders) |
| Comparable | Largest IPO in history (beats Aramco 2019) |
| Lockup | Standard 180 days for insiders (TBC at S-1/A) |
What “fixed-price” means here
Unlike a traditional book-built IPO where the underwriters bring price discovery into the offering, SpaceX set $135 in advance. Institutional investors had a binary choice: subscribe or pass. The order book closed June 10, 2026.
This is rare for US IPOs at this scale (Aramco 2019 used a similar structure on the Saudi exchange). The effect: less price discovery before the market open, more volatility in the first 30–90 minutes of trading.
Day-one playbook
09:30 ET open
Expect SPCX to print an opening cross 10–35% above $135. With $250B in demand vs $75B available, supply will be scarce on day one. The opening cross typically reflects unsatisfied institutional demand plus opportunistic retail.
| Scenario | Opening print | Probability (subjective) |
|---|---|---|
| Cool open | $140–$148 | 15% |
| Base case | $150–$165 | 50% |
| Hot open | $165–$180 | 25% |
| Blow-off | $180–$200+ | 10% |
First hour
Expect 20–40% intraday range. Heavy short interest will not be available immediately (borrow takes 1–3 days to establish). Most volume will be momentum buying, hedge-fund allocations getting rebalanced, and retail FOMO.
First close
Historically, mega-IPOs with this level of oversubscription close day one above the opening cross but below the intraday high. A reasonable base case is a $155–$170 first close.
First week
This is where things get interesting. Lockups for some pre-IPO allocations may differ from the standard 180 days. Watch for greenshoe option exercise (usually 15% of offered shares) and MSCI/Nasdaq-100 inclusion mechanics.
What could go wrong on day one
| Risk | Likelihood |
|---|---|
| Nasdaq opening delay (large auctions sometimes delay open by 30+ min) | High |
| Halt for volatility (10% moves can trigger halts) | Medium |
| Allocation disputes (large IPOs occasionally see post-print reallocation drama) | Low |
| Musk tweet that moves the stock pre-open | Always non-zero |
How to actually buy SPCX as retail
If you did not get IPO allocation (you almost certainly did not):
- Wait 5–15 minutes after open for liquidity to deepen and the opening volatility to settle.
- Use limit orders only. Market orders into a hot IPO open are how you buy the top.
- Size it small. Day-one IPOs of mega-caps routinely give back 20%+ in the first month.
- Decide your thesis. Are you buying Starlink? Launch services? xAI exposure via SPCX? Each has different risk.
Comparable IPO opens
| IPO | Year | Open vs IPO price | First-month return |
|---|---|---|---|
| Saudi Aramco | 2019 | +10% | +10% |
| Alibaba | 2014 | +38% | +20% |
| 2012 | +11% | -25% | |
| 2004 | +18% | +30% | |
| 2024 | +48% | +1% | |
| Arm | 2023 | +25% | +20% |
The Facebook 2012 cautionary tale (NASDAQ trading glitch + lockup-driven sell-off) is the bear case worth knowing.
What SPCX gives you exposure to
| Business | Approx % of value (est.) |
|---|---|
| Starlink | ~50% |
| Falcon 9 + Starship launch services | ~25% |
| xAI / Grok (post-Feb 2026 merger) | ~15% |
| Starshield (defense) | ~5% |
| Other (R&D, real estate) | ~5% |
See xAI exposure via SPCX for why this is the cleanest publicly-traded way to own Grok.
Index inclusion math
SPCX at $1.77T immediately qualifies for:
- S&P 500 — eventual inclusion likely Q4 2026 or Q1 2027 after profitability and listing-history requirements are confirmed
- Nasdaq-100 — likely within 6–9 months
- MSCI USA — inclusion confirmed per recent reports
Index inclusion is a meaningful tailwind: passive flows from index funds typically buy ~5–15% of float on inclusion.
