The $730 Billion Question: Can OpenAI Justify Its Valuation as Nvidia Commits $30 Billion?

When Nvidia reportedly commits $30 billion to invest in a company, the natural question is not just about Nvidia — it is about whether that company deserves the extraordinary valuation being placed upon it. OpenAI, expected to be valued at $730 billion in its next funding round, faces that question head-on, even as Nvidia’s commitment represents one of the most powerful votes of confidence it could receive.
The history of Nvidia’s financial relationship with OpenAI adds important context. A previous $100 billion deal, announced last September, dissolved this month after it emerged that the arrangement — structured around chip purchase commitments — was never formally binding. The collapse was damaging to both companies’ credibility and contributed to market instability. The new $30 billion equity deal is designed to be everything the previous arrangement was not: clean, binding, transparent, and free of circular structures.
With that cleaner deal in place, attention shifts to the valuation question. A $730 billion price tag would make OpenAI one of the most valuable private companies in history, rivaling SpaceX in that exclusive ranking. The figure implies that investors expect OpenAI to grow dramatically from its current position — despite the fact that its current position includes declining market share, ongoing cash burn, and a yet-to-be-proven path to profitability.
The headwinds are real. ChatGPT’s market share has dropped from 86.7% to 64.5% in a single year. Anthropic has made significant gains in enterprise markets, positioning itself as a premium, ad-free alternative. OpenAI’s advertising experiments have attracted criticism and may complicate its brand positioning. Its chip procurement strategy is in flux, with AMD and Broadcom partnerships adding complexity to the hardware picture.
Despite all of this, a coalition of major investors — reportedly including Amazon, SoftBank, and Microsoft, alongside Nvidia — appears ready to support the $730 billion valuation through a $100 billion funding round. SoftBank has publicly hedged, but its participation seems likely. The question of whether that valuation is warranted will not be answered by any single funding announcement — it will be answered by OpenAI’s performance over the coming years. Nvidia, for one, is betting that the answer will be yes.
