OpenAI Closes US$122 Billion Round at US$852 Billion Valuation
- OpenAI said it had closed US$122 billion in committed capital at a post-money valuation of US$852 billion, its largest round, with SoftBank co-leading alongside Andreessen Horowitz, D.E. Shaw Ventures, MGX, TPG and T. Rowe Price[1][4]
- The round began as US$110 billion on 27 February 2026 against a US$730 billion pre-money valuation, with US$50 billion from Amazon and US$30 billion each from Nvidia and SoftBank, and was left open for more investors[5]
- Wikipedia describes the February tranche as already surpassing the prior largest private technology fundraise in history, and CNBC later called the final US$122 billion a record-breaking round[2][3]
- About US$3 billion came from individual investors through bank channels, OpenAI was set to appear in several ARK Invest ETFs, and its revolving credit facility grew to about US$4.7 billion, all ahead of an expected IPO[1]
- OpenAI claimed US$2 billion of revenue a month, more than 900 million weekly users and over 50 million subscribers; on 28 May rival Anthropic raised US$65 billion at a US$965 billion valuation, topping OpenAI's value[1][3]

TechCrunch[5] (31 March 2026, 'has closed a deal to raise $122 billion') and PYMNTS[4] (31 March, 'Tuesday (March 31) press release') agree; CNBC[3] later called it OpenAI's record-breaking round. Wikipedia[2] cites an OpenAI post dated 24 March and says 'April', so the exact date of OpenAI's own post is less clear; 31 March is the closing news both press reports give.

Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most. A picture that shows something else, or shows it badly, is looked at too, and moved down or replaced.
