Anthropic IPO Could Become Largest in History; 2026 U.S. Equity Offerings Set to Surpass 2021 Peak
nashnova research
Anthropic's IPO and private placement could raise up to $90.4 billion combined, topping SpaceX's record — while 2026 U.S. equity issuance has already passed $425 billion, surpassing the 2021 peak. AI is resetting how much capital markets can absorb in a single cycle.
How big is $90.4 billion?
At the top of its pricing range, Anthropic's IPO plus private placement would raise $90.4 billion, surpassing SpaceX's $86.2 billion listing in June.
If the greenshoe is exercised — an option letting underwriters sell extra shares — the total breaks $100 billion, exceeding Meta's roughly $98 billion equity-raise announced last month.
This means → a company less than a decade old is raising more in a single deal than the world's largest tech incumbents.
Why is 2026 U.S. issuance hitting a record?
Per Bloomberg data, U.S. listed companies have raised over $425 billion in 2026 through IPOs, at-the-market programs, and private placements — past the 2021 peak of roughly $408 billion.
The three largest IPOs in U.S. history landed within months of each other, all AI-related. Even inflation-adjusted, this year's biggest IPOs dwarf prior record-holders Saudi Aramco and Visa.
In plain terms = the 2021 wave was a broad market boom; this one is almost entirely one sector — AI — dragging the entire market's fundraising ceiling higher.
Is SK Hynix's $26.5 billion listing still big?
SK Hynix completed a $26.5 billion U.S. listing in July, a record for a non-U.S. company listing in America.
Adjusted for inflation, though, that figure is comparable to Alibaba's 2014 and SoftBank's 2018 IPOs from decades ago.
This reflects how AI-era fundraising has shifted the scale of what counts as a "mega IPO" — yesterday's records now sit in the middle of the pack.
What is an ATM — and why are tech giants suddenly using it?
An ATM — at-the-market offering, a program that lets a company sell shares gradually on the open market without a single fixed-price deal — has surged in the AI era.
Meta's plan includes $60 billion via ATM; Google's roughly $85 billion raise contains a $40 billion ATM tranche; Oracle has sold about $20 billion through ATM. Bitcoin-treasury firm Strategy also raised $21 billion via ATM this year.
This means → AI hasn't just broken IPO records — it has pulled tech giants back into equity markets after decades away, with ATM as their standard tool for continuous capital replenishment.
What comes next?
Anthropic's IPO pricing is expected on November 18, with trading set to begin on November 19.
Whether the deal prices at the top of its range will be a direct test of how much AI-company valuation the market can absorb.
In plain terms = if buyers pay full price, confidence in AI is still far from peaking; if they don't, the ceiling may already be near.
