OpenAI lands monster $110B round at $730B valuation

If you thought AI fundraising was starting to cool down, OpenAI just obliterated the scale entirely.

OpenAI announced a staggering $110 billion funding round at a $730 billion pre-money valuation. To put that in perspective, this single check dwarfs the entire market capitalization of most legacy tech giants.

The mega-round to end all mega-rounds

The investor roster reads like an alliance of tech titans. Amazon led the pack with a massive $50 billion investment, alongside a new multi-year strategic partnership.

SoftBank poured in $30 billion, doubling down on its aggressive AI playbook. NVIDIA also put up $30 billion, effectively recycling hardware capital straight back into its biggest customer.

Following the round, the stake held by the nonprofit OpenAI Foundation is now worth over $180 billion. That easily cements it as one of the best-funded philanthropic vehicles in human history, targeted at health breakthroughs and AI safety.

900 million users and a 5-gigawatt appetite

OpenAI shared some jaw-dropping traction metrics to back up the price tag. ChatGPT now commands over 900 million weekly active users, with consumer subscribers topping 50 million.

Growth is not slowing down either. OpenAI noted that January and February are pacing to be the largest months for new subscriber additions in the company's history.

On the enterprise side, more than 9 million paying business users now rely on ChatGPT for work. Meanwhile, weekly users for its coding engine Codex have tripled since early this year, hitting 1.6 million.

Serving that much intelligence requires an astronomical amount of power. Along with the funding, OpenAI secured 3 gigawatts of dedicated inference capacity and 2 gigawatts of training capacity on NVIDIA's upcoming Vera Rubin systems.

That hardware commitment comes on top of the existing Hopper and Blackwell deployments already running across Microsoft Azure, Oracle Cloud Infrastructure, and CoreWeave.

Why it matters

We think this round marks the official transition of frontier AI from high-stakes software development into heavy industrial infrastructure. You can no longer compete at this level without national-grid-scale power and sovereign-scale balance sheets.

For everyday users and developers, the immediate win is capacity. A massive 5-gigawatt pipeline of compute means fewer outages, faster responses, and lower risk of rate limits as agentic workflows become standard.

Strategically, bringing Amazon in for $50 billion is a masterstroke. It significantly dilutes OpenAI's historical reliance on Microsoft, diversifying both its cloud compute footprint and its enterprise distribution channels.

That said, the stakes could not be higher. At a valuation north of $800 billion post-money, OpenAI has zero room for error. It now carries the burden of proving that artificial general intelligence can generate hundreds of billions in real economic returns before the capital bills come due.
