Anthropic is reportedly preparing for an IPO that could raise close to $100 billion — which, if it happens at that scale, would be more than 3.4 times the size of the current record holder, Saudi Aramco's $29.4 billion 2019 listing. Nvidia is separately reported to be in talks to anchor the raise with an investment of up to $10 billion. As of September 13, 2026, none of this is confirmed by an actual filing — it's reported, from unnamed sources, by multiple financial outlets whose own numbers don't fully agree with each other.
TL;DR
| Question | Answer |
|---|---|
| Confirmed or reported? | Reported — "targets," "mulling," "in talks," per Yahoo Finance, Benzinga, 24/7 Wall St. No filing confirmed |
| How much is Anthropic trying to raise? | Reportedly close to $100 billion |
| At what valuation? | Reported inconsistently: $2 trillion by some outlets, $2.3 trillion by others |
| How big would this IPO be, historically? | ~3.4x Saudi Aramco's $29.4B 2019 raise, the current largest IPO ever |
| Who's anchoring it? | Nvidia, reportedly in talks for up to $10 billion |
| What's Anthropic's actual revenue? | Reported annualized run rate ~$65B by end of July 2026, up from ~$9B end of 2025; projected $190-200B by 2028 |
What's actually confirmed versus still "in talks"
It's worth being unusually precise here, because the reporting itself is inconsistent on the headline number. Yahoo Finance and Benzinga both frame Nvidia's role as "in talks" for an investment of up to $10 billion as part of Anthropic's IPO — language that signals active discussion, not a signed term sheet. On the valuation, Benzinga's framing cites the deal as being discussed at "nearly $100 billion" raised at a "$2 trillion" valuation, while 24/7 Wall St. and Yahoo Finance separately cite $2.3 trillion. Neither figure has converged into a single number across outlets, which is itself informative: valuations in live, ongoing fundraising talks routinely move during negotiation, and the reporting discrepancy is more consistent with "talks are still happening" than with "a number editors just transcribed slightly differently."
None of the sourcing found describes an S-1 filing, an underwriter selection, or a locked timeline. Treat every number in this post as reported and preliminary, not confirmed, until Anthropic makes its own announcement.
The scale, in context
If Anthropic does raise anywhere close to $100 billion, it would not be a large IPO by AI-industry standards — it would be the largest IPO ever completed, in any industry, by a wide margin. Saudi Aramco's December 2019 listing, which raised $29.4 billion, has held the record for nearly seven years. A $100 billion Anthropic raise would be roughly 3.4x that figure.
For comparison, some of the largest tech IPOs in history — Alibaba's 2014 listing ($25 billion), Meta's 2012 listing ($16 billion), Uber's 2019 listing ($8 billion) — sit well below even Aramco's figure, let alone the number being discussed for Anthropic. This isn't a company going public at a scale comparable to prior tech listings; it would be an entirely new tier.
The revenue numbers behind the valuation
The valuation figures make more sense against Anthropic's reported growth trajectory. Anthropic's annualized revenue run rate is reported at roughly $65 billion by the end of July 2026 — up from approximately $9 billion at the end of 2025, a more than sevenfold increase in about seven months. Projections cited alongside the IPO reporting put Anthropic's 2028 revenue at $190-200 billion.
At a $2-2.3 trillion valuation against a ~$65 billion current run rate, the implied multiple is in the low-to-mid 30s on trailing revenue — high by the standards of traditional public-market valuations, but broadly consistent with how growth-stage frontier AI companies have been valued throughout 2026, where revenue growth rates well above 100% year-over-year have repeatedly justified multiples that would look extreme in slower-growing sectors.
Why Nvidia specifically, and why this fits a pattern
Nvidia anchoring a customer's IPO with a direct equity investment is not an isolated move — it's consistent with the compute-financing strategy explainx.ai covered in detail in Is Nvidia the "Central Bank of AI"?, which documented roughly $300 billion in guarantees, backstops, and direct equity stakes Nvidia has extended across its customer base to keep demand for its chips growing even as its biggest customers (the hyperscalers) increasingly design competing custom silicon. A $10 billion anchor position in Anthropic's IPO would be a smaller, more conventional version of the same underlying incentive: Nvidia benefits directly from Anthropic's continued growth and compute spend, and taking an equity stake aligns Nvidia's own upside with a major customer's success rather than treating the relationship as a pure vendor transaction.
This also isn't Nvidia's first reported move toward Anthropic specifically — explainx.ai has separately covered Nvidia's ~$99 billion equity book, a broader (and separately unverified, viral-thread-sourced) claim about the scale of Nvidia's direct equity holdings across the AI industry, of which an Anthropic IPO stake would be one additional, this time far better-sourced, data point.
What builders should take from this, before it's confirmed
Nothing in this reporting changes anything about Claude's pricing, API terms, or product availability today — an IPO changes a company's capital structure and public reporting obligations, not (immediately) its product roadmap. The signal worth tracking here is less about Anthropic specifically and more about what it implies for the broader compute-financing web: if Anthropic does go public at anywhere near a $2 trillion valuation, with Nvidia as an anchor investor, that further entangles Nvidia's own financial health with a specific frontier lab's continued growth and IPO performance — exactly the kind of circular financing relationship The Economist's "central bank of AI" analysis flagged as worth monitoring for anyone dependent on stable compute pricing.
The practical move for now: treat every number in this story — the $100 billion raise, the $2 trillion or $2.3 trillion valuation, the $10 billion Nvidia stake — as reported and subject to change until Anthropic makes its own confirmed announcement, and watch for whether the eventual real figures land closer to the low or high end of what's currently being reported.
What an IPO of this scale would actually change
Going public typically changes three things for a company like Anthropic that a private funding round doesn't: quarterly earnings disclosure obligations (revenue, spending, and growth metrics become public and scrutinized every three months instead of surfacing only through leaks and reported figures like the ones in this post), a broader and more liquid shareholder base subject to public-market pressure for near-term results rather than the longer time horizons typical of venture and strategic investors, and — specific to Anthropic's Public Benefit Corporation structure — a test of whether founder super-voting shares and charter commitments actually hold up against public-market pressure the way they're designed to. Anthropic has structured itself explicitly to resist the kind of investor pressure that reportedly contributed to OpenAI's November 2023 governance crisis, but that structure has never been tested against the specific pressures of quarterly public reporting and a much larger, more liquid shareholder base than it has today.
There's also a competitive dimension worth noting, though it's a separate report explainx.ai hasn't independently verified: other coverage circulating alongside this story claims Sam Altman has ruled out a 2026 IPO for OpenAI, which carries its own reported valuation around $1.6 trillion. If that holds and Anthropic does go public in 2026 at a valuation reported as $2-2.3 trillion, it would do so before its largest direct competitor — a sequencing worth watching but not yet something to treat as confirmed on either side.
Why the valuation discrepancy itself is a useful signal
The gap between "$2 trillion" and "$2.3 trillion" — a 15% swing on a headline number this large — is worth dwelling on rather than glossing over, because it tells you something about how to read every other figure in this story. Financial reporting on private-company valuations during active fundraising talks is almost always sourced from people close to the negotiation who are describing a moving target, not a settled figure pulled from a signed document. A $300 billion difference between two outlets' reported valuation isn't a rounding error or a transcription mistake at that scale — it's evidence that whatever number Anthropic and its bankers are discussing internally has moved between whenever each outlet's sources last checked in and publication.
This matters practically for how to treat every other number in this post. The "$100 billion raise" figure, the "$10 billion" Nvidia stake, and the "$65 billion revenue run rate" numbers all come from the same category of reporting — informed, plausible, but pre-confirmation. None of them should be treated as fixed until Anthropic's own S-1 filing (if one materializes) locks in exact figures. Readers citing this story elsewhere should carry that caveat forward rather than treating any single number here as the final word, especially given how much the individual figures already diverge across outlets covering the same underlying talks.
