For years, Anthropic lived in OpenAI's shadow. That chapter is officially over.

On May 28, 2026, Anthropic announced a staggering [**$65 billion Series H funding round**](https://jang.com.pk/en/66627-anthropic-overtakes-openai-as-worlds-most-valuable-ai-startup-news?ref=zilck.com), vaulting the company to a [**$965 billion valuation**](https://www.cnbc.com/2026/05/28/anthropic-open-ai-startup-value.html?ref=zilck.com) — surpassing rival OpenAI's $852 billion mark and crowning Anthropic as the world's most valuable AI startup. This reflects a fundamental shift in how the enterprise world is betting on artificial intelligence.

## From Safety Lab to Silicon Valley King

[Anthropic was born in 2021](https://jang.com.pk/en/66627-anthropic-overtakes-openai-as-worlds-most-valuable-ai-startup-news?ref=zilck.com) when Dario Amodei, Daniela Amodei, and a group of former OpenAI researchers walked out the door over concerns about the pace and safety of AI development. Their founding thesis — that AI should be built with constitutional principles baked in from day one — was considered idealistic by some, niche by others. Today, it looks prescient.

The company's rise has been nothing short of meteoric. In February 2026, Anthropic raised a [$30 billion Series G](https://finance.yahoo.com/news/anthropic-surpasses-openai-ai-cash-204112269.html?ref=zilck.com), pushing its valuation to $380 billion. Just three months later, the Series H round more than doubled that figure. The speed of that climb is nearly unprecedented in venture capital history.

## The Enterprise Play That Changed Everything

While OpenAI captured the world's imagination with ChatGPT's consumer appeal, Anthropic quietly built a different kind of machine — an **enterprise-first revenue engine**. The results speak for themselves: Anthropic's annualized revenue crossed [**$47 billion in May 2026**](https://www.morningstar.com/stocks/anthropic-bests-openai-valuation-race-hitting-965b?ref=zilck.com), up from $14 billion as recently as February, compared to OpenAI's estimated $30 billion. Meanwhile, Anthropic reported its **first-ever quarterly profit of $559 million** in Q2 2026, while OpenAI projected a staggering [**$14 billion loss**](https://www.youtube.com/watch?v=7Up6-DHmaTk&time%5Fcontinue=0&source%5Fve%5Fpath=MjM4NTE&embeds%5Freferring%5Feuri=https%3A%2F%2Fwww.perplexity.ai%2F&embeds%5Freferring%5Forigin=https%3A%2F%2Fwww.perplexity.ai&ref=zilck.com) for the year.

Claude's dominance in the B2B space is hard to overstate. Anthropic now holds an estimated [**54% of the enterprise coding market**](https://www.youtube.com/watch?v=7Up6-DHmaTk&time%5Fcontinue=0&source%5Fve%5Fpath=MjM4NTE&embeds%5Freferring%5Feuri=https%3A%2F%2Fwww.perplexity.ai%2F&embeds%5Freferring%5Forigin=https%3A%2F%2Fwww.perplexity.ai&ref=zilck.com). Major consulting firms, including KPMG and PwC, have made sweeping commitments to Claude, with PwC alone deploying 30,000 certified professionals on the platform.

## Who's Backing the Bet?

The Series H round attracted a marquee list of investors that reads like a who's who of global finance. **Altimeter Capital, Dragoneer, Greenoaks, and Sequoia Capital** co-led the round, joined by Capital Group, Blackstone, Brookfield Asset Management, Fidelity, General Catalyst, and Temasek, among many others. Notably, the round also included [**$15 billion previously committed by Amazon and other hyperscalers**](https://www.morningstar.com/stocks/anthropic-bests-openai-valuation-race-hitting-965b?ref=zilck.com) — a signal that cloud giants are doubling down on Anthropic as their preferred AI infrastructure partner.

[Strategic backers](https://economictimes.indiatimes.com/markets/us-stocks/news/anthropic-overtakes-openai-ai-valuation-race-enters-hyperdrive/the-funding-frenzy/slideshow/131383749.cms?ref=zilck.com) like Samsung, Micron Technology, and SK Hynix also participated, underscoring that hardware and chip manufacturers are aligning themselves with Anthropic's long-term roadmap.

## What This Means for the AI Race

OpenAI isn't going anywhere. With an $852 billion valuation and the world's most recognized AI brand, it remains one of the most powerful companies in tech. But the gap has closed — and in one key metric, it has been crossed. The real story here isn't a knockout blow; it's the emergence of a [**genuinely competitive AI duopoly**](https://economictimes.indiatimes.com/markets/us-stocks/news/anthropic-overtakes-openai-ai-valuation-race-enters-hyperdrive/slideshow/131383810.cms?ref=zilck.com), each with distinct strategic identities: OpenAI's consumer-facing reach versus Anthropic's enterprise depth and profitability discipline.

Both companies are now eyeing [IPOs in the near future](https://investinginai.substack.com/p/anthropic-vs-openai-which-ipo-should). When they hit public markets, investors will face a fascinating choice between two very different visions of what AI's commercial future looks like — and Anthropic, for the first time, arrives at that conversation as the one sitting at the top of the table.
