Nvidia CEO Jensen Huang said the chipmaker’s recent $30 billion investment in OpenAI could be its last before the AI firm potentially goes public later this year.

Huang added that a larger $100 billion investment in OpenAI, a figure previously highlighted as part of a major infrastructure partnership announced in September, is likely “not in the cards.”

“The reason for that is because they’re going to go public,” Huang said during the Morgan Stanley Technology, Media & Telecom Conference on Wednesday.

He also said Nvidia’s $10 billion investment in Anthropic would likely be its final stake in the OpenAI rival.

Nvidia had earlier disclosed plans to invest in Anthropic in a November announcement made alongside Microsoft.

Huang’s remarks follow months of speculation over the extent of Nvidia’s collaboration with OpenAI.

The chipmaker noted in a November quarterly filing that the previously announced $100 billion deal might not materialize, while the Wall Street Journal reported in January that the agreement was “on ice.”

Nvidia’s $30 billion investment in OpenAI was announced as part of a $110 billion funding round unveiled by the startup on Friday.

The round also featured a $50 billion pledge from Amazon and a $30 billion commitment from SoftBank.
