OpenAI reportedly raises $15B at a $1.25T valuation

The funding round comes as OpenAI faces a massive capital race against rival Anthropic, which is preparing for a public stock market debut.

$1.25TReported pre-money valuation for OpenAI

The short version

Why it matters

This story highlights the extreme amount of capital required to build and maintain the infrastructure for advanced AI models. It also sets the stage for a direct public comparison between the two leading AI companies once Anthropic goes public.

The $1.25 trillion valuation

OpenAI is reportedly in the process of raising $15 billion in new capital. This funding round values the company at $1.25 trillion, a figure that represents a significant jump from its previous valuation in March 2026. While the company initially sought $30 billion from investors, the current reported amount is roughly half of that original goal.

The $1.25 trillion figure is considered a pre-money valuation, which is the value of a company before new investment is added. This amount is about 47% higher than the $852 billion post-money valuation OpenAI received during its $122 billion funding round in March 2026. The lower-than-expected raise suggests that investor demand may not have fully matched the company's initial ambitions for the round.

Despite the lower funding amount compared to its goals, the valuation still reflects a massive upward trajectory for the company. OpenAI has climbed quickly through successive funding rounds since its founding in 2015. It has become one of the most valuable private technology companies in the world due to the commercial success of ChatGPT and its broader AI platform.

Funding the AI infrastructure

The primary reason OpenAI requires such massive amounts of capital is the cost of developing and operating advanced AI models. These systems require heavy spending on computing infrastructure, including data centers and specialized chips. Even with strong revenue growth, the company must continuously pay for the computing capacity needed to train and run its models.

Major tech players are providing the backbone for this expansion. According to reports from CNBC, Nvidia has provided OpenAI with approximately $30 billion in funding. Additionally, SoftBank has contributed about $65 billion to the company's capital needs. These investments are essential for OpenAI to maintain its lead in the rapidly evolving AI landscape.

OpenAI's financial health shows a mix of high growth and high costs. The company's revenue rose about 50% between the second and third quarters of this year. Information from The Information put the third-quarter revenue at about $10 billion, yet this high revenue has not removed the immediate need for fresh capital to cover infrastructure commitments.

The race with Anthropic

OpenAI's funding news arrives just as its primary rival, Anthropic, prepares for a major move into the public markets. Anthropic, the maker of the Claude AI model, is planning an initial public offering (IPO). The IPO is priced to imply a valuation of up to $1.3 trillion, which would put it in the same league as OpenAI's reported valuation.

Anthropic has been moving quickly to secure its own capital. In early 2026, it secured $30 billion in Series G funding at a $380 billion valuation. Shortly after, it raised another $65 billion in Series H funding, which briefly made it the world's most valuable private AI company before OpenAI's recent news.

The Wall Street Journal reports that Anthropic shares could begin trading on the Nasdaq under the ticker 'ANT' as soon as November 19 or 20. The company plans to sell 825 million shares at a price range of $70 to $78 each. This move will create a direct public comparison between the two companies' finances and growth rates.

Public markets and scrutiny

The upcoming IPO for Anthropic will shift how the public perceives the AI industry. Once Anthropic lists, investors will be able to compare the finances and growth of the two leading AI companies directly. This transparency will bring more scrutiny to the

What comes next for AI

The competition between OpenAI and Anthropic is intensifying as both companies seek to dominate the AI market. As Anthropic prepares to go public, the market will be watching to see if public investors are willing to pay the same high premiums that private investors have paid for OpenAI. The next few weeks will be a critical period for determining how the market values the future of AI infrastructure and profitability.
