OpenAI secures $110 bn funding, valued at $840 bn, as Amazon pledges $50 bn and exclusive

OpenAI announced a $110 billion financing round that lifts its post‑money valuation to $840 billion, according to The Guardian. The deal is led by Amazon, which contributes $50 billion, while Nvidia and SoftBank each commit $30 billion, a breakdown echoed by Engadget. Crunchbase News lists the round among the ten largest ever recorded, underscoring its historic scale.

The Amazon investment comes with an exclusive cloud‑services pact. Tom’s Hardware reports that OpenAI will run its Frontier enterprise platform on AWS, with Amazon supplying 2 gigawatts of its custom Trainium silicon. In return, AWS becomes the sole cloud distributor for the platform, cementing a deep technical integration between the two firms.

User growth accelerates alongside the funding. TechCrunch notes that ChatGPT now registers 900 million weekly active users and 50 million paying subscribers, marking the strongest subscriber momentum in OpenAI’s history. The company’s blog attributes the surge to faster responses, higher reliability, and stronger safety features, which it says improve “as usage scales.”

OpenAI is also expanding its research footprint. Wired reports that the firm will transform its London office into the largest non‑U.S. research hub, a move positioned to “scale AI for everyone.” The expansion aligns with the funding’s stated goal of broadening AI accessibility across regions and industries.

Analysts view the $840 billion valuation as a bet on OpenAI’s first‑mover advantage. The Guardian highlights that the round positions the company ahead of rivals such as Anthropic and Google, while the exclusive Amazon partnership locks in a critical cloud infrastructure advantage. With the financing now in place, OpenAI is poised to accelerate both its enterprise sales and its global research network, setting a new benchmark for AI‑centric capital markets.
