Anthropic in Talks for $30 Billion Round at $900 Billion Valuation, Leapfrogging OpenAI

Anthropic is in early talks to raise at least $30 billion at a valuation exceeding $900 billion, according to multiple sources familiar with the matter. Bloomberg reports that the round could close as soon as the end of May 2026, though no term sheet has been signed and the deal remains far from finalized. The proposed valuation represents a nearly 2.4x jump from the $380 billion post-money valuation Anthropic achieved in February 2026, when it closed its Series G round.

The speed of this escalation is striking. CNBC noted back in February that Anthropic's previous $30 billion raise ranked as the second-largest private tech financing on record, trailing only OpenAI's $40 billion-plus round. Now, just three months later, the company is attempting to double its valuation and surpass OpenAI, which was last priced near $852 billion at the end of March 2026 according to Heygotrade. Forbes characterized the potential round as a definitive move to top OpenAI in the private valuation hierarchy. The compressed timeline between major financings suggests investors are treating frontier AI development as a capital-intensive arms race where falling behind on funding equates to competitive extinction.

The $900 billion figure would place Anthropic among the most valuable private companies in history, and the trajectory raises questions about how investors are modeling returns. Traditional venture math breaks down when valuations approach a trillion dollars in private markets. The company generated revenue at a fraction of this implied value, yet investors are clearly betting on exponential growth in enterprise AI adoption rather than near-term financial metrics.

Bloomberg Law's reporting emphasized that the talks are preliminary and could still collapse. This uncertainty matters because Anthropic's previous round in February attracted a who's-who of institutional investors including GIC, Coatue, D. E. Shaw Ventures, Dragoneer, and Founders Fund, with participation from BlackRock, Fidelity, and General Catalyst. The diversity of this investor base, spanning sovereign wealth, hedge funds, traditional VC, and corporate backers, indicates that Anthropic has successfully positioned itself as a must-own asset across capital markets. If the new round proceeds at these terms, it would signal that limited partners are accepting dramatically different risk-return profiles for AI infrastructure plays than they would for any other technology category.

Amazon and Google remain Anthropic's lead backers, which means public market exposure to the company's upside flows primarily through AMZN and GOOGL equity rather than direct investment opportunities. This corporate backing structure creates unusual incentives. Both cloud giants have poured billions into Anthropic through convertible notes and direct equity, with Amazon reportedly committing up to $4 billion and Google investing over $2 billion in prior rounds.

The strategic nature of these investments complicates pure financial analysis. For Amazon and Google, Anthropic represents both a hedge against OpenAI-Microsoft dominance and a direct pipeline for AI infrastructure demand. Heygotrade's analysis highlighted that public investors seeking Anthropic exposure are effectively buying these cloud giants or the broader AI semiconductor supply chain including NVIDIA. The $900 billion valuation would validate their earlier bets enormously, but it also raises the question of whether either company would permit dilution that substantially reduces their influence. Dario and Daniela Amodei, who founded Anthropic in 2021, have maintained unusual control for a company at this scale, and any new round's governance terms will be scrutinized closely for signs of founder-investor tension.

The funding arms race between Anthropic and OpenAI is reshaping how AI companies are built and sustained. OpenAI's reported $852 billion valuation and Anthropic's potential $900 billion mark suggest the two companies are converging on a similar capital intensity model. Both require massive compute infrastructure, expensive talent acquisition, and prolonged R&D cycles before clear monopoly economics emerge.

This dynamic has secondary effects across the industry. Anthropic's February funding round explicitly targeted frontier research, product development, and infrastructure expansion. The new capital would presumably accelerate these same vectors, particularly as the company pushes its Claude models into enterprise coding and automation workflows where it has gained traction. Bloomberg's sources indicated the round is expected to attract many of the same investors from prior rounds, suggesting a self-reinforcing capital network is forming around the company. For smaller AI competitors, this concentration of funding in the top two players creates a widening gap that may prove impossible to bridge without similar corporate backing or government support.

A successful $900 billion financing would trigger cascading consequences across technology markets. First, it would force institutional investors to mark their existing Anthropic holdings to this new valuation, creating paper gains that could flow through to LP distributions or be reinvested. Second, it would establish a new pricing benchmark for AI startups at every stage, potentially inflating valuations across the sector before revenue multiples have any chance of catching up.

Third, and perhaps most consequentially, it would intensify pressure on OpenAI to respond with its own capital raise or accelerate plans for a public offering. The two companies have been locked in a feature and model release cadence that mirrors their fundraising competition. Bloomberg Law's caution that the deal is not finalized should be taken seriously, given the extraordinary size and the compressed timeline. If the round fails to materialize, or closes at a reduced valuation, it could signal that even the most aggressive AI investors are encountering limits to how much private capital can be absorbed by pre-revenue frontier models. Either outcome, the market will be watching closely.
