Wall Street is about to face a problem it has never had before: three companies worth a combined $3 trillion all trying to go public in the same calendar year, and not enough investor money to fund all of them.

SpaceX is launching its roadshow as early as June, according to Reuters, targeting a $75 billion raise. OpenAI and Anthropic are expected to follow in the second half of 2026. Together, the three could absorb over $240 billion in investor demand. That would make this the most crowded IPO year in history, and it is already forcing companies like Canva and Databricks to rethink their timing.

PitchBook analyst Kyle Stanford warned Reuters that the broad IPO reopening companies have spent years waiting for could get pushed to 2027. Bankers are already telling pre-IPO software companies to avoid conflicting with SpaceX's timeline. The signal is clear: there is a pecking order now, and if you are not SpaceX, OpenAI, or Anthropic, you wait.

Anthropic Just Passed OpenAI in Revenue

The most stunning development heading into these IPOs is Anthropic's revenue surge. The company reported annualized revenue exceeding $30 billion, eclipsing OpenAI's $24 billion run rate. At the start of 2025, OpenAI was generating $6 billion annually to Anthropic's $1 billion. That gap has not just closed. It has reversed.

Anthropic's secret weapon is Claude Code and its suite of enterprise AI tools. While ChatGPT has far more individual users, Anthropic discovered what OpenAI is now scrambling to replicate: the real money is in tokens, not users. A single developer burning through Claude Code generates more revenue than thousands of free ChatGPT users combined.

OpenAI's investors push back on the comparison. Khosla Ventures partner Ethan Choi argued that Anthropic counts revenue on a gross basis without subtracting the cut it pays to cloud providers like AWS and Azure, while OpenAI reports net revenue. He called the comparison "apples to oranges." That is a fair accounting point. But the trajectory is the story, and Anthropic's trajectory is terrifying if you own OpenAI shares.

The Oxygen Problem

Reuters reported that the SpaceX deal alone could claim an outsized share of investor demand. SpaceX is planning to reserve up to 30% of its IPO for retail investors, a move that could soak up individual investor capital that might otherwise flow to OpenAI or Anthropic.

The math is brutal. SpaceX at $1.75 trillion valuation. OpenAI targeting close to $1 trillion. Anthropic at $380 billion and climbing. That is more than $3 trillion in combined value seeking public market validation in the same year. For context, total US IPO proceeds in a typical strong year are around $50 to $70 billion. These three companies alone could dwarf that by a factor of four.

The companies that get hurt worst are the ones that have been waiting patiently. Canva, valued at over $50 billion. Databricks, worth $62 billion. Stripe. Discord. All of them have been circling the IPO window for years. Now three mega-companies are about to slam it shut.

What This Means

If you are an early employee at a Series D startup hoping 2026 is the year you finally get liquid, start adjusting your expectations. The IPO market is about to become a velvet rope, and only the trillion-dollar companies are getting past the bouncer.

SpaceX goes first. Then OpenAI and Anthropic fight for whatever appetite remains. Everyone else takes a number. The age of the mega-IPO is here, and it belongs to exactly three companies.
