OpenAI has officially closed its latest funding round with $122 billion in committed capital, marking the largest single funding round in Silicon Valley history and cementing the ChatGPT maker's position as the most valuable private AI company in the world. Announced on March 31, 2026, the round values OpenAI at $852 billion post-money, a staggering figure that surpasses the market capitalizations of most S&P 500 companies. The funding was anchored by major investors including SoftBank, NVIDIA, and Amazon, with continued participation from Microsoft and Andreessen Horowitz (a16z). Notably, the round also includes $3 billion from retail investors through a unique structure that allows public market participation ahead of OpenAI's anticipated IPO. The capital infusion comes as the company prepares for a potential blockbuster public offering targeted for Q4 2026, with analysts speculating about a $1 trillion valuation target. Despite the massive funding and growing monthly revenue, OpenAI remains unprofitable, raising questions about the sustainability of the AI investment boom.

OpenAI announced on March 24th the closure of its AI video generation platform Sora and the termination of its $1 billion partnership agreement with Disney. CEO Sam Altman stated that the company will shift its strategy towards enterprise level productivity tools and coding tools, and the Sora team will turn to world simulation research for long-term development of robotics technology, in preparation for the planned IPO.
