Three Trillion-Dollar IPOs in One Summer
In the span of 30 days, three companies collectively valued at over $3.5 trillion have filed to go public. Nothing like this has happened before in capital markets history.
| Company | Filing | Pre-IPO Valuation | Target Date |
|---|---|---|---|
| SpaceX | Public S-1 (May 20) | $1.77T | June 12, 2026 |
| OpenAI | Confidential S-1 (June 8) | $852B–$1T+ | September 2026 |
| Anthropic | Confidential S-1 (June 1) | $965B–$1.8T | October 2026 |
Combined, these three companies represent the largest wave of technology IPOs since the dot-com era — except the scale is 100x larger.
How We Got Here
The AI infrastructure buildout of 2024-2026 created a new class of company that scaled faster than anything before:
Anthropic went from $87M ARR in January 2024 to $47B ARR by May 2026 — a 540x increase in 28 months. Claude Code, the AI coding assistant, was the primary growth accelerator.
OpenAI hit $2B/month in revenue but is spending even faster — projecting $14B in losses for 2026, with profitability not expected until ~2030.
SpaceX combined with xAI in February 2026, creating a $18.7B revenue entity where only Starlink ($11.4B, $7.2B EBITDA) is profitable. The xAI division is burning $6.4B annually.
The Revenue Reality
| Company | Annual Revenue | Profitable? | Growth |
|---|---|---|---|
| SpaceX (combined) | $18.7B | Starlink only | Mixed |
| OpenAI | ~$24B run-rate | No ($14B loss projected) | Rapid |
| Anthropic | ~$47B run-rate | Q2 2026 may be first | 540x in 28 months |
Anthropic stands out as the only one approaching profitability at speed. OpenAI has the widest gap between revenue and profitability. SpaceX's Starlink is proven but the xAI segment is a significant drag.
What This Means for Investors
If You Hold Pre-IPO Shares
- Lock-up terms will define your liquidity timeline — each company has different structures
- SpaceX's staggered unlock (detailed in our pricing analysis) is the most complex
- OpenAI and Anthropic lock-ups won't be known until their full S-1s go public (~15 days before roadshow)
If You're Considering Buying
- SpaceX secondary shares at ~$129 (Forge) vs. $135 IPO price — narrow spread
- OpenAI and Anthropic secondary markets will tighten as IPO dates approach
- The window for pre-IPO exposure is closing fast for all three
The Sequencing Matters
SpaceX goes first (June 12). Its performance sets expectations:
- Strong debut → validates trillion-dollar tech IPOs, bullish for OpenAI/Anthropic
- Weak debut → could delay or reprice the others
- Volatility → creates trading opportunities in the secondary market
The IPO Calendar
| Date | Event |
|---|---|
| June 11 | SpaceX IPO pricing confirmed |
| June 12 | SPCX begins trading on Nasdaq |
| Mid-summer | Databricks S-1 expected ($134B) |
| ~September | OpenAI IPO target |
| ~October | Anthropic IPO target |
Plus Databricks ($134B, profitable, $5.4B ARR) is expected to file mid-summer — the "boring" but potentially best-performing IPO of the bunch.
Beyond the Big Three
The IPO pipeline extends well beyond the headline names:
| Company | Valuation | Status |
|---|---|---|
| Databricks | $134B | S-1 expected mid-summer |
| Anduril | $61B | No S-1; IPO "in next few years" |
| Ramp | $44B | Strong IPO candidate, FCF positive |
| Perplexity AI | ~$21B | No IPO signals yet |
| Helion Energy | $15.5B | Pre-revenue, Microsoft PPA |
| Shield AI | $12.7B | Pentagon contracts accelerating |
| WHOOP | $10.1B | CEO says "last private round" |
This is the most active period for pre-IPO markets since the 1990s. The combination of AI scaling, defense tech resurgence, and pent-up LP demand for liquidity is creating unprecedented deal flow.
