The $3 Trillion AI IPO Wave: SpaceX, OpenAI, and Anthropic All Filing in 30 Days

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.
