The two labs were on pace to absorb more than a third of all startup capital. ## OpenAI asked for $1.4 trillion and closed at $1.25 trillion In late September, [OpenAI](https://theinference.org/markets/companies/openai) entered funding talks seeking at least $30 billion at a $1.4 trillion valuation, up from its last mark of $852 billion [1]. Investors called the terms too lofty, a November 5 selloff erased $2.5 trillion from the Nasdaq, and the company cut its valuation target to $1.25 trillion and the raise by a third [1][3]. [The first $11 billion closed on November 6](https://theinference.org/article/openai-trimmed-its-round-to-20-billion-at-a-1-25-trillion-valuation-with-11-billion-committed) with SoftBank and MGX participating, and the remainder, now up to $20 billion, wraps in the weeks ahead [2][3]. ## Two marks price the whole market OpenAI and [Anthropic](https://theinference.org/markets/companies/anthropic) were on pace to absorb [more than a third of all capital invested in startups globally this year](https://www.bloomberg.com/news/articles/2026-11-11/openai-anthropic-valuations-fuel-vc-fears-of-startup-correction), per Bloomberg Intelligence [1]. So their marks set everyone else's. B Capital co-founder Howard Morgan is telling founders who wanted high single-digit billions, some of them with zero revenue, that the number is "too high given your current revenues," and Theory Ventures' Tomasz Tunguz says conservative multiples arrived within two weeks [1]. If Anthropic's listing falters, "some companies are going to go out of business," says Sapphire Ventures president Jai Das [1]. *Chart: **OpenAI closed $150B under its ask; Anthropic's IPO tops out at $1.405T** Bar chart of valuation marks for OpenAI and Anthropic, from OpenAI's $852 billion last round and $1.4 trillion September ask to its $1.25 trillion November close, and from Anthropic's $965 billion May round to the $1.405 trillion top of its IPO range and bankers' $1.5 trillion-plus* *Valuation marks in US dollars. OpenAI's last round and September ask per Bloomberg; its $11 billion close at $1.25 trillion per Reuters. Anthropic's May round and the top of its IPO range per its filing, via CNBC; the bankers' $1.5 trillion-plus is an estimate reported by the FT via Business Standard. [1][2][5][8]* ## Usage is climbing while the ceiling falls The repricing is not a demand story. OpenAI's [quarterly revenue jumped nearly 50% to $10 billion](https://finance.yahoo.com/markets/article/billionaire-venture-capitalist-vinod-khosla-says-judge-ai-by-usage-not-stock-prices-190230250.html) [4], and Anthropic's run-rate revenue reached about $81 billion at the end of October [5]. Vinod Khosla, the Sun Microsystems co-founder and early OpenAI backer, says usage, measured in tokens, is the number to watch, not price swings [4]. The strain sits with the payers: combined free cash flow at [Amazon](https://theinference.org/markets/companies/amazon), [Alphabet](https://theinference.org/markets/companies/alphabet), [Meta](https://theinference.org/markets/companies/meta), [Microsoft](https://theinference.org/markets/companies/microsoft) and [Oracle](https://theinference.org/markets/companies/oracle) ran at about minus $31 billion in the third quarter, per [Goldman Sachs](https://theinference.org/markets/companies/goldman-sachs), after positive quarters through 2025 [4]. ## The public market sets its price on November 18 Anthropic, the five-year-old maker of Claude, [offers 825 million shares at $70 to $78 on November 18](https://theinference.org/article/anthropic-files-for-ipo-at-70-to-78-a-share-near-1-trillion-with-amazon-s-239-billion-mark-on-the-line), trading the next day on Nasdaq as ANT, topping out at $1.405 trillion fully diluted against a $965 billion May round [5]. [AMD](https://theinference.org/markets/companies/amd), [Broadcom](https://theinference.org/markets/companies/broadcom), Google, [Micron](https://theinference.org/markets/companies/micron), Microsoft, [Nvidia](https://theinference.org/markets/companies/nvidia) and [TSMC](https://theinference.org/markets/companies/tsmc) have committed $26 billion at the IPO price, and the book was covered at launch, with bankers weighing pricing above the range toward $1.5 trillion [5][8]. ## CoreWeave's one-day rebound shows demand is still there [CoreWeave's 24.71% earnings-day rebound](https://www.cnbc.com/2026/11/11/coreweave-crwv-outlook-earnings-ai.html), after a 65% slide from May, shows how fast demand returns when numbers land [6][7]. If Anthropic prints above $1.25 trillion, public buyers are paying more than private money would bear for its rival; the 20% retail slice, triple the norm, is the demand that has to hold [5]. ## Takeaway Private money capped OpenAI at $1.25 trillion. On November 18 public buyers are asked to pay $1.405 trillion for Anthropic. ## Sources 1.
