HEADLINE: OpenAI Closes $110B Funding Round at $840B Valuation, Largest Startup Raise on Record

ARTICLE:

OpenAI has closed a $110 billion funding round at an $840 billion post-money valuation, marking the largest fundraise in startup history, the company announced. The round included participation from Amazon, NVIDIA, and SoftBank.

The closure comes after months of negotiations that began in December. In concurrent disclosures, OpenAI revealed significant user growth: weekly Codex users have more than tripled since the start of the year to 1.6 million, up from 1 million as of early February. The company also reported more than 9 million paying business users now rely on ChatGPT for work.

The timing reflects intensifying competition for AI dominance, with OpenAI simultaneously navigating positioning discussions with the Department of War—a dynamic that has created divergent strategies among AI leaders, including Anthropic's reported refusal of certain terms.

For CFOs evaluating enterprise AI spend, the funding validates ChatGPT's commercial traction in business workflows, though the valuation's sustainability depends on converting user growth into durable revenue streams.
