On June 1, the AI lab behind Claude quietly filed a confidential S-1 with the SEC. No ticker, no Anthropic stock price, no fixed date, just an option to go public once regulators sign off. Standard playbook for a mega-IPO. What’s not standard is the number attached to it: bankers are floating a listing valuation near $2 trillion, built on projections that revenue hits $190-200B by 2028.
- Current valuation: $965B (Series H, closed May 28, 2026)
- IPO status: confidential S-1 filed with the SEC, June 1, 2026
- Expected listing window: Q4 2026, unconfirmed
- Discussed IPO valuation: up to roughly $2T
- Share price / ticker: not set yet
Search “when is Anthropic IPO” right now and you’ll find a lot of guesswork sitting on top of those five facts. The rest of this piece covers what tends to happen in the months before a filing like this actually prices, and how to get exposure to the stock without waiting for it.
What’s confirmed and what’s just a number bankers like
The company’s last priced valuation is $965 billion, set by a $65B Series H round that closed in late May. The $2 trillion figure making headlines is a discussed target for the eventual listing, based on 2028 revenue projections, not a confirmed IPO price. Treat it as a talking point bankers use in pitch decks, not something written into a prospectus yet.
There’s no share count either, and confidential filings like this one can sit with the SEC for months before anything becomes public. Buying at a $2T entry point already assumes years of near-flawless execution. That’s a demanding starting line. The more useful question isn’t what happens on listing day. It’s what happens before it, and there’s a recent case worth studying.
The pre-IPO trade already played out once this year
A different mega-IPO went through this exact cycle a few months back. In the run-up, a handful of smaller, loosely related stocks doubled in value purely on proximity to the buzz. Then the real listing happened, and one of those proxy stocks dropped almost 11% in a single session as money rotated out.
The pattern: capital moves into the names sitting next to the story first, and it can leave fast once the real listing goes live.
The SpaceX precedent
That earlier example was SpaceX. It priced its IPO on June 12 at roughly $135 a share after months of hype. Rocket Lab, Intuitive Machines and Firefly Aerospace all roughly doubled beforehand, since SpaceX itself wasn’t tradeable yet. The day SpaceX actually started trading, Rocket Lab fell almost 11%.

Anthropic and SpaceX aren’t the same story. Different sector, different fundamentals. But the mechanics of a mega-IPO tend to repeat: hype flows into anything adjacent beforehand, then drains out fast once the real thing lists.
Who’s already riding the AI infrastructure boom
A few companies don’t build any AI models themselves, but their revenue is tied directly to how much is being spent on AI compute right now:
- Riot Platforms (~$8B market cap): Bitcoin miner turned AI-compute host, sitting on a $9B infrastructure contract
- TeraWulf (~$9B): leasing out data center capacity in a deal reportedly worth $19B
- Hut 8 (~$12B): a $7B data center lease
- Akamai (~$15B): a $1.8B cloud infrastructure agreement

None of these show up in the AI lab’s own revenue line. All four get a bump whenever big compute news breaks, and tend to give it back once the real listing arrives, if the Rocket Lab pattern above holds.
There’s more capital chasing this trade than one IPO can explain. Alphabet raised $85 billion in a single week in June purely to fund AI data centers. OpenAI filed its own confidential IPO paperwork a week after Anthropic’s, and both are now racing for the same pool of year-end investor capital:
| Anthropic | OpenAI | |
|---|---|---|
| Confidential S-1 filed | June 1, 2026 | June 8, 2026 |
| Last priced valuation | $965B (Series H) | $852B |
| Reported listing target | Q4 2026, unconfirmed | Fall 2026, possibly slipping to 2027 |
A few analysts have already flagged that overlap as a supply risk for both deals; too many mega-IPOs competing for the same buyers in the same quarter tends to compress pricing for whoever lists second.
Anthropic and OpenAI are just two names in a much wider trade. For a broader view, see our roundup of the top AI stocks to trade in 2026.
How to trade it before the listing
There’s no live Anthropic stock price on any exchange yet, and most “when will it IPO” articles stop right there. But Anthropic is already tradeable on IQ Option, months ahead of any Nasdaq debut, through Perpetual Futures that track its current private valuation.

No expiry, no accredited-investor paperwork, no waiting on a roadshow. And leverage up to 20x.
In real numbers: put down $100, and at 20x you’re controlling a $2,000 position. A 5% move in the valuation in your favor turns into roughly 100% on that $100, not 5%. The same math runs the other way: a 5% move against you and the $100 is gone just as fast.
Bottom line
Still no set date, no confirmed IPO price, no ticker. Banks are deep in diligence, and confidential S-1s can sit for months. What the SpaceX listing showed is that the real move often happens before the prospectus goes public, in the smaller names sitting next to the story. And that trade doesn’t require a bank’s permission to enter.
