OpenAI Discusses $750 Billion Valuation: A 5x Jump in Just 14 Months

For existing investors like Microsoft (which owns 49% of OpenAI's for-profit arm), a $750B valuation would represent extraordinary paper gains. Microsoft's initial $1B investment in 2019 could be worth over $100B.

For new investors, the high valuation raises questions about realistic returns. At 187x revenue, OpenAI would need to grow revenue to $50B+ to justify the valuation by traditional software metrics.

For the broader AI ecosystem, this signals continued investor appetite for frontier AI despite concerns about profitability. It also pressures competitors like Anthropic, Mistral, and xAI to raise at similarly aggressive valuations.
