OpenAI has closed a $122 billion funding round at an $852 billion post-money valuation, marking one of the largest capital raises in tech history. The investment, led by Amazon, NVIDIA, and SoftBank, will accelerate development of OpenAI's unified AI superapp strategy and expand compute infrastructure across multiple cloud and silicon partners.

This funding represents a massive vote of confidence in OpenAI's vision to become the core infrastructure for AI development. The company has grown from 10 million users in its fastest-ever platform launch to over 900 million weekly active users across ChatGPT, with enterprise revenue now representing 40% of total revenue. OpenAI's revenue has scaled from $1 billion annually to $2 billion monthly in just over a year.

OpenAI is building a unified AI superapp that combines ChatGPT, Codex, browsing, and agentic capabilities into one integrated experience. This strategy aims to translate model capability directly into user adoption while creating operating leverage through improved infrastructure and expanded deployment. The company has expanded its compute partnerships beyond NVIDIA to include AMD, AWS Trainium, Cerebras, and its own custom silicon with Broadcom, positioning itself for the next phase of AI scaling.
