Amazon.com Inc has had discussions to invest as much as $50 billion and SoftBank Group Corp has held talks to invest as much as $30 billion. The Financial Times previously reported Nvidia might invest as much as $20 billion.

Nvidia and OpenAI have been linchpins of the AI boom, but their relationship has come under new scrutiny in recent days amid reports of tensions between the two firms. The Wall Street Journal reported on Friday that a plan that Nvidia announced in September to invest as much as $100 billion in OpenAI overall had stalled after some inside the chip giant expressed doubts about the deal.

The chief executives of both companies have since publicly said they remain committed to working together.

“We will definitely participate in the next round of financing because it’s such a good investment,” Nvidia CEO Jensen Huang told reporters while visiting Taipei on Saturday.

He added that it would potentially be “the largest investment we’ve ever made.”
