OpenAI Nears $850 Billion Valuation with $100 Billion Funding Round as Anthropic Challenges Dominance

OpenAI is reportedly finalizing a funding round that could exceed $100 billion, pushing its valuation to over $850 billion. This development comes as rival Anthropic shows rapid revenue growth, with some projections indicating it could surpass OpenAI in revenue by next year. The intense competition between the two AI leaders was recently highlighted by an awkward public encounter between their CEOs.

Bloomberg, citing anonymous sources, reported that the initial phase of OpenAI's latest funding round is expected to secure more than $100 billion. Following this investment, the company's valuation could reach $850 billion, surpassing an earlier estimate of $830 billion. This valuation positions OpenAI comparably to the combined market capitalization of major companies such as Intel, Boeing, McDonald's, Nike, and Starbucks.

The investor lineup for this round is anticipated to include significant commitments, with Amazon potentially investing up to $50 billion, SoftBank around $30 billion, and Nvidia discussing an investment of approximately $20 billion. Microsoft is also reportedly involved.

OpenAI's Rapid Fundraising Trajectory

OpenAI's financial journey began in late 2015 as a non-profit organization, backed by an initial pledge of $1 billion from figures like Elon Musk and Sam Altman, with a stated goal of developing general artificial intelligence for humanity's benefit.

By 2019, facing substantial operational costs, OpenAI transitioned to a "capped-profit" model. Microsoft invested $1 billion that year, becoming a key strategic partner. The investment agreement stipulated that investor returns would be capped at 100 times their principal, with any excess directed to the non-profit entity.

The launch of ChatGPT in early 2023 significantly boosted OpenAI's profile, attracting over 100 million users within two months. This led to an additional $10 billion investment from Microsoft and participation from venture capital firms like Sequoia, A16Z, and Thrive Capital, valuing OpenAI at approximately $29 billion.

In October 2024, OpenAI completed another $6.6 billion financing round, raising its valuation to $157 billion, making it the world's second-largest unicorn after SpaceX. Thrive Capital led this round, with participation from Microsoft, Nvidia, and SoftBank.

Early 2025 saw the emergence of "Project Stargate," a plan involving OpenAI, SoftBank's Masayoshi Son, and Donald Trump to invest $500 billion in U.S. AI infrastructure over four years, with OpenAI as a central player. The current $100 billion funding round is expected to support this initiative, particularly in building a 10-gigawatt AI-exclusive supercomputing network globally and accelerating the development of GPT-5 series models. Despite these investments, the company's losses are projected to expand to around $14 billion in 2026.

Anthropic's Challenge and Growth

While OpenAI secures massive funding, Anthropic, founded in 2021 by former OpenAI research VP Dario Amodei, is rapidly gaining ground. Amodei and other researchers left OpenAI due to disagreements over its commercialization strategy, subsequently establishing Anthropic with a focus on "safety-first" AI and developing the Claude product.

According to data analysis by Epoch AI, Anthropic's annualized revenue growth rate is approximately 10 times per year, compared to OpenAI's 3.4 times, when measured from the point both companies surpassed $1 billion in annualized revenue. This analysis suggests Anthropic could overtake OpenAI in revenue by mid-2026, with both companies potentially reaching around $43 billion in annualized revenue.

Epoch AI's analysis used exponential trend fitting, showing high R² values of 0.99 for OpenAI and 0.98 for Anthropic, indicating stable growth patterns. However, internal projections from both companies are more conservative. OpenAI reportedly anticipates a revenue growth rate of about 2.2 times in 2026, while Anthropic expects less than 4 times. Epoch AI also noted a slowdown in Anthropic's actual growth rate since July 2025, from 10 times to approximately 7 times per year. Even with these conservative estimates, the revenue intersection point between the two companies is still projected for 2026 or 2027.

Anthropic's growth is largely driven by its strong performance in the enterprise sector, with partnerships with Infosys and Amazon AWS. Claude has gained traction among paying customers for enterprise-level applications such as code assistance, knowledge management, and complex reasoning. Recent reports suggest Anthropic has also completed a Series G funding round of up to $30 billion.

Advertising and Public Rivalry

OpenAI has begun testing advertising features in free and paid versions of ChatGPT, integrating "product recommendation" ads into conversational scenarios with initial partners like Best Buy and Expedia. This move aims to monetize ChatGPT's user base and broaden commercialization avenues.

In response, Anthropic aired advertisements during the Super Bowl that depicted an AI assistant inserting irrelevant ads, a direct critique of OpenAI's strategy. Anthropic's ads implied a commitment to an ad-free experience for Claude users. Sam Altman subsequently addressed the matter on social media.

The competition between the two companies has extended beyond technical development to market strategies, public perception, and advertising.

A Public Snub

The rivalry was publicly underscored at the India AI Impact Summit, where Prime Minister Modi attempted to facilitate a symbolic handshake among AI leaders, including Google CEO Sundar Pichai, OpenAI's Sam Altman, and Anthropic's Dario Amodei. During a group photo, Modi encouraged the leaders to hold hands to signify unity. While others complied, Altman and Amodei, standing next to each other, did not shake hands, instead raising clenched fists. This image quickly circulated on social media, with observers interpreting it as a clear sign of their ongoing competition. Altman later dismissed the incident in a CNBC interview, stating he was "just a little confused."

Future Outlook

OpenAI's substantial funding is earmarked for supercomputing infrastructure, model development, and potential advertising initiatives, with an eventual IPO in view. Anthropic's rapid growth suggests it could soon rival OpenAI in revenue. Nvidia is strategically positioned, investing in both companies while supplying essential hardware. Amazon and SoftBank are also significant investors.

The current landscape indicates an ongoing AI infrastructure arms race, demanding massive investments in computing power, data, and model capabilities. Commercialization pressures are driving AI companies to develop diverse revenue models, including subscriptions, advertising, API calls, and enterprise services. Regulatory frameworks for AI are also rapidly evolving across major countries, which will influence future competition. The pace of development and investment in the AI sector suggests a limited window for slower, more deliberative approaches.
