Top U.S. antitrust enforcers are moving forward with investigations into the roles played by Microsoft, OpenAI and Nvidia in the artificial intelligence boom, according to a report.

The rapid development of generative AI since the 2022 release of ChatGPT has raised concerns over whether these three companies will play an outsized role in the new sector.

Workers at tech giant Samsung Electronics in South Korea staged the first strike at the company on Friday, the head of a major union representing tens of thousands of people told AFP.

CBS News reported that Nvidia surpassed Apple in market capitalization on Wednesday, securing the second position behind Microsoft. This shift reflects investors' confidence in the chipmaker's role in driving the artificial intelligence revolution.

U.S. chip titan Intel on Tuesday struck a defiant tone in the face of strong challenges from rivals Nvidia, AMD and Qualcomm, unveiling technologies it said would lead the artificial intelligence revolution.

AMD on Monday announced its new artificial intelligence chips for everything from cutting-edge data centres to advanced laptops, ramping up its challenge to the runaway market leader Nvidia.

Demand has exploded in the past two years for the specialised processors that help develop, train and run AI applications such as ChatGPT.

The chief executives of OpenAI, Microsoft and Google are among the high-profile members of a new federal board created to advise the U.S. government on the "safe and secure" development of artificial intelligence.

The intense earthquake that rattled Taiwan early Wednesday, led to equipment damage at the semiconductor giant Taiwan Semiconductor Manufacturing Company (TSMC). Despite the initial impact, most machinery at the chipmaker resumed normal operations within the day.

Nvidia on Monday unveiled its latest family of chips for powering artificial intelligence, as it seeks to consolidate its position as the major supplier to the AI frenzy.

U.S. Commerce Secretary Gina Raimondo has urged lawmakers, Silicon Valley and U.S. allies to stop China from getting semiconductors and cutting-edge technologies key to national security.

Speaking at an annual national defense forum in Simi Valley, California, Raimondo called Beijing "the biggest threat we've ever had" and stressed "China is not our friend."

Whether they sell smartphones, ads or computer chips, the heavyweights of Silicon Valley have everything to prove to investors looking to see who is best placed in the race to dominate the generative artificial intelligence market.

"If you're a company, and you don't have an AI message, you're not going to be in business very long," says independent industry analyst Jack Gold.
