Nvidia Is Probably Done Investing in OpenAI and Anthropic, Says CEO-Why?

At the Morgan Stanley Technology, Media, and Telecom conference in San Francisco on Wednesday, Jensen Huang said Nvidia is likely done investing in AI giants OpenAI and Anthropic.
The $30 billion investment it just finalized into OpenAI was a steep drop from the $100 billion deal announced last September, and will likely be the last check. Same for the $10 billion it put into Anthropic in November.
The official reason sounds clean: Both companies appear to be heading toward IPOs later this year, and private deals of this nature close once that window opens.
