President Donald Trump will meet with Nvidia Corp. Chief Executive Officer Jensen Huang at the White House on Friday as the US prepares to tee up tariffs on semiconductors, weighs the fate of a subsidy program and probes whether Chinese AI startup DeepSeek skirted export controls to obtain the chipmakers’ products.

On Tuesday afternoon, President Donald Trump held a press conference to announce Stargate, a $500 billion artificial intelligence (AI) infrastructure project in the United States. He called it the "largest AI infrastructure project, by far, in history."

OpenAI is in talks for an investment round to raise nearly $40 billion that would value the AI startup at up to $340 billion, the Wall Street Journal reported on Thursday.

SoftBank Group shares jumped after the company and ChatGPT-maker OpenAI announced plans to invest up to half a trillion dollars in artificial-intelligence infrastructure in the U.S. Shares rose 8.8% to 10,060 yen, or equivalent to $64.69, on Wednesday in Tokyo, after climbing as much as 9.2% earlier, to their highest level since July.

Softbank Group Corp is in talks to invest up to US$25 billion in ChatGPT owner OpenAI, according to a person familiar with the matter, as the Japanese conglomerate continues to expand into the sector.

OpenAI has announced that it's teaming up with Softbank and Oracle on $100 billion data center project in the U.S.

The recovery came after US chipmaker Nvidia closed up 9 per cent on Tuesday, recouping some of the heavy losses that wiped $600bn off its market capitalisation at the start of the week, when investors fretted over the threat from China’s DeepSeek to the US supremacy in artificial intelligence.

Now that it's the world's most valuable company, some investors might believe the time to buy Nvidia has already passed, but these developments show that's not the case. Furthermore, the stock is currently selling for just 32 times next year's expected sales, a remarkably attractive price for a company with so much opportunity.

Reports began circulating this week that SoftBank is in talks to invest as much as $25 billion into OpenAI, a move that would position the Japanese operator as the generative AI (gen AI) company’s biggest financial backer.

SoftBank's investment in OpenAI may position the company as the world's joint-second most valuable private tech firm after SpaceX.
