How OpenAI’s $122 billion fundraise stacks up against rivals

OpenAI’s latest $122 billion fundraise at a post-money valuation of $852 billion cements its position as the dominant force in the artificial intelligence (AI) race. The round was led by heavyweight backers including Amazon, Nvidia, and SoftBank, with Microsoft continuing its support.

OpenAI’s growth metrics highlight its lead in consumer adoption. A company blog post said that:

• OpenAI became the fastest technology platform to reach both 10 million and 100 million users and now projects hitting one billion weekly active users.
• The company is generating $2 billion in monthly revenue, a sharp jump from $1 billion per quarter by the end of 2024.

In the same blog post, the company claims its revenue is growing four times faster than earlier internet giants like Alphabet and Meta did at similar stages.

How it stacks up against rivals

Despite OpenAI’s lead, competition remains intense. Anthropic, valued at $380 billion after a $30 billion Series G round in February, is carving out a strong enterprise niche. Its annual run-rate revenue stands at $14 billion, growing over 10x annually for three consecutive years.

Anthropic’s Claude ecosystem is gaining traction. The company revealed that customers spending over $100,000 annually have grown 7x year-on-year (YoY), while more than 500 customers now spend over $10 million annually, up from just a dozen two years ago.

Notably, eight of the Fortune 10 are Claude customers. Its Claude Code product alone has crossed $2.5 billion in run-rate revenue since launching in May 2025, it said.

While OpenAI focuses on horizontal scale by building a mass-market artificial intelligence (AI) platform powered by compute infrastructure, Anthropic is pursuing a vertical, enterprise-first strategy.

Big Tech’s massive spends

Meanwhile, Big Tech is accelerating AI investments. Meta reported $59.89 billion in Q4 revenue and $200.97 billion annually, up 24% and 22% YoY. It expects Q1 2026 revenue of between $53.5 and $56.5 billion and full-year expenses of $162–169 billion, driven largely by infrastructure and hiring of tech talent.

Across the industry, Microsoft, Amazon, Alphabet, and Meta are projected to spend $635 billion on AI infrastructure in 2026, up from $383 billion in 2025 and just $80 billion in 2019. Alphabet alone expects capital expenditure of $175-185 billion.

However, heavy spending is weighing on investor sentiment. Meta’s stock fell 19% in March, wiping out $310 billion in market value, amid concerns over AI costs and legal risks as the platform faced scrutiny for social media addiction and teenage safety cases.

Google’s quiet scale-up

Google’s Gemini ecosystem is also gathering pace. By early 2026, it reported 750 million monthly app users and two billion monthly users for AI Overviews. Enterprise adoption is also rising, with over eight million paid seats across 2,800 companies and 13 million developers building on its models, a blog post by the company said.

Traffic-tracking website Similarshowed that Gemini captured 39–40% of ChatGPT’s share in December, with 1.1 billion monthly visits and 157% growth in 2025.

The bottom line

The AI market is consolidating around a few infrastructure-scale players. OpenAI leads in capital, distribution, and consumer reach, but rivals are gaining ground through enterprise focus and ecosystem integration.
