OpenAI seeks $28B funding to surpass Anthropic in AI race

The capital race has become the AI race

OpenAI’s latest funding push is not just another private round. It is a direct move in a tightening contest with Anthropic, the rival AI lab now preparing for a highly watched public-market debut. The core figure in the current reports is a financing target framed by 36Kr as 200 billion yuan, or roughly 28 billion dollars, while Reuters-syndicated reporting describes the effort as an unusually fast round of about 30 billion dollars that could value OpenAI at more than 1.4 trillion dollars [1][2]. The difference between the two figures is best understood as a question of currency conversion and reporting shorthand; the strategic point is the same: OpenAI wants to secure a very large pool of capital before Anthropic absorbs investor bandwidth.

The timing is central. Reuters reported that OpenAI is racing to obtain investor commitments before Anthropic’s expected public-market debut in mid-November 2026, citing people familiar with the matter [2]. That makes the round a pre-emptive maneuver as much as a financing exercise. OpenAI is not merely asking investors to fund model development; it is trying to define the benchmark for the next phase of AI-company valuations before public investors get a fuller look at Anthropic’s numbers.

Why OpenAI wants the money now

The immediate logic is scale. OpenAI needs capital to train and serve increasingly expensive AI models, and Reuters’ video report said the company is in talks with investors for a round of about 30 billion dollars at a valuation of more than 1.4 trillion dollars [3]. That would place OpenAI among the most valuable private companies in the world and would give it more room to finance compute, data-center access, enterprise expansion and the operating costs of frontier AI systems.

The round also appears designed to protect OpenAI against market timing. Investors familiar with the company told Reuters that OpenAI needs capital to fund substantial infrastructure commitments and strengthen its balance sheet if weaker IPO markets delay its own planned 2027 listing [2]. In other words, the financing is both offensive and defensive. Offensively, it helps OpenAI compete for customers, researchers and compute. Defensively, it reduces dependence on an IPO window that could close if market volatility deepens.

That defensive motive matters because public and private AI valuations are now being scrutinized more closely. Reuters reported that IPO plans have been affected by volatility, concerns about AI infrastructure costs and pressure on companies tied to data-center expansion [2]. For OpenAI, closing a private round before those concerns intensify could preserve optionality. It can keep expanding while delaying the more intrusive financial disclosures that come with a public offering.

Anthropic is forcing the comparison

Anthropic is the reason the clock is ticking. The company behind Claude is expected to test public-market demand soon, and Reuters reported that some investors view OpenAI’s fundraising push as an attempt to lock in capital from funds that might otherwise allocate more money to Anthropic’s IPO [2]. That is the heart of the current story: the two companies are competing not only for model leadership, enterprise contracts and talent, but for the same pool of global institutional money.

OpenAI’s pitch is built around acceleration. The company has told investors that growth strengthened after the launch of GPT-6 Astra, with annualized revenue reaching 50 billion dollars and potentially rising to 70 billion dollars by year-end, according to Reuters-syndicated reporting [2]. It has also argued that price cuts on cheaper models have increased usage and that further price reductions remain possible [2]. That pitch is meant to show investors that lower prices do not necessarily weaken the business if usage expands quickly enough.

Anthropic’s figures create a sharp comparison. Reuters reported that Anthropic’s annualized revenue had reached roughly 65 billion dollars by July, while the company told investors that third-quarter revenue rose to 16.8 billion dollars from 11.6 billion dollars in the second quarter [2]. Yet the same reporting said slowing month-to-month growth had raised investor concerns about Anthropic’s valuation [2]. For OpenAI, that gives the fundraising push a tactical edge: close the round before investors use Anthropic’s IPO documents to build a stricter side-by-side valuation model.

A fight over revenue quality

The numbers are large, but the accounting debate may be just as important. Reuters reported that OpenAI records revenue on a net basis, subtracting partner shares upfront, while OpenAI has accused Anthropic of inflating revenue by counting the full value of contracts sold through third-party cloud providers [2]. Anthropic has told Reuters that it follows established accounting practices [2]. This dispute matters because AI companies often depend on complex cloud, reseller and infrastructure relationships that can make headline revenue less straightforward than it appears.

For investors, the central question is not simply which company is growing faster. It is which revenue base is more durable, which margins can improve, and which business model can absorb the cost of serving frontier models. Reuters’ video report noted that investors have concerns about competition from Anthropic and open-source models, along with questions about margins, profitability and how long OpenAI will need to support a capital-intensive operating model [3]. That framing is crucial: OpenAI may be growing rapidly, but the company still has to convince investors that scale can eventually translate into attractive economics.

This is why a 28 billion to 30 billion dollar raise is strategically meaningful. The money can buy time. It can fund infrastructure before revenues fully mature. It can reassure partners that OpenAI has balance-sheet depth. And it can signal to customers that the company will remain one of the dominant providers of advanced AI systems even as competitors narrow technical gaps.

Investors are being asked to choose before the public data arrives

The current race is unusual because it asks investors to commit before the market has a clear public comparison. OpenAI’s private round would allow the company to set its own valuation before Anthropic’s IPO creates a visible benchmark [2]. Edward Best, co-chair of capital markets at Willkie Farr & Gallagher, told Reuters on a hypothetical basis that OpenAI may want to set its valuation without having to worry about a direct comparison [2]. That observation captures the financial logic behind the accelerated timetable.

The competition is also becoming more symbolic. Reuters’ video report described OpenAI and Anthropic as locked in a heated rivalry, with both companies competing on frontier model capabilities and high-value AI use cases [3]. Anthropic was founded by former OpenAI employees, and the two companies increasingly face each other in enterprise sales, developer adoption and investor roadshows [3]. The funding race therefore reflects a deeper identity contest: which lab will be seen as the default platform for the next generation of AI applications?

Public-benefit narratives are entering the valuation story

The financing battle is unfolding alongside a broader public-market narrative about how AI companies justify their scale. AP reported that Anthropic and OpenAI are moving toward major public offerings while outlining ideas for sharing AI-generated wealth with the public [4]. That matters because trillion-dollar valuations invite questions about social legitimacy as well as financial performance.

Anthropic has leaned into that issue. AP reported that Anthropic said on Sunday, October 18, 2026, that it would commit 5 percent of its shares to a new public-benefit fund, pending stockholder approval [5]. AP also reported that the fund could support nonprofits or potentially distribute money to specific populations, while Anthropic said the shares would not be used for lobbying or political giving [4][5]. These announcements do not directly change OpenAI’s fundraising mechanics, but they shape the environment in which investors will judge the company’s public responsibilities.

OpenAI has its own governance and public-benefit narrative, and AP noted that executives at both Anthropic and OpenAI have argued that AI’s gains should eventually benefit everyday people [4]. As the companies approach enormous valuations, those claims become part of the investor conversation. A funding round this large is no longer only about product-market fit; it is also about whether society and regulators will accept the concentration of value inside a handful of AI labs.

What to watch next

The first question is whether OpenAI can close the round before Anthropic’s expected mid-November debut. If it succeeds, OpenAI could secure a major pool of capital before investors have access to Anthropic’s public filing and market pricing. If it struggles, the company may have to negotiate in the shadow of Anthropic’s disclosures, including revenue quality, growth trajectory and investor appetite for AI infrastructure risk.

The second question is whether the reported valuation above 1.4 trillion dollars holds. Reuters reported that some existing and prospective Anthropic investors have argued for a valuation closer to 1.5 trillion dollars for Anthropic’s debut rather than the 2 trillion dollars the company wanted after third-quarter results came in below expectations [2]. If both companies converge around similar valuation ranges, the market may begin treating OpenAI and Anthropic as a two-company referendum on the economics of frontier AI.

The third question is whether capital intensity becomes a ceiling. OpenAI’s reported raise would provide enormous resources, but it also reinforces the idea that frontier AI requires constant access to vast sums of money. The more these companies raise, the more investors will demand proof that revenue growth, pricing strategy and infrastructure spending can produce lasting returns.

For now, OpenAI’s message is clear: it wants to move before Anthropic sets the public benchmark. The reported 28 billion dollar funding push is therefore not just a balance-sheet event. It is a race to define the AI market’s next valuation standard, secure the deepest pools of investor capital and preserve the initiative before the rivalry moves from private negotiations to Wall Street.
