US AI companies

US House Speaker Mike Johnson says President Trump's meeting with technology chief executives will focus on finding the right balance on artificial intelligence. The discussion is expected to weigh innovation and industry growth against regulation and safety concerns. The meeting brings the Trump administration face to face with leading AI companies as Washington shapes its approach to governing the fast-moving technology.

New York City has subpoenaed Elon Musk and his artificial intelligence company xAI as part of an investigation into AI safety. The move makes the city one of the most prominent US local governments to target a major AI developer directly, and it adds regulatory pressure for Musk, whose AI business is already drawing scrutiny alongside his other ventures.

Reports say China may permit ByteDance and Alibaba to purchase Nvidia's RTX PRO 5500 chips, a possible easing of restrictions on advanced US semiconductors for major Chinese tech firms. The move would matter for AI computing capacity at two of China's largest companies and could signal a shift in US-China technology trade tensions. Details on timing and conditions of any approval remain unclear.

AMD is acquiring Fei-Fei Li's 3D world-modeling startup in a deal valued at US$8.2 billion, with the technology expected to inform the design of the company's future AI chips. The move signals AMD's push to strengthen its position in the AI silicon market against rivals like Nvidia, betting that spatial and world-modeling AI will shape next-generation computing.

Samsung has announced a plan to invest one billion US dollars in Helix, an AI infrastructure company, according to an official statement from the company. The move signals Samsung's continued push into artificial intelligence hardware and services at a time when global tech firms are racing to secure computing capacity and data-center resources.

Alibaba is reportedly close to receiving Chinese approval to purchase Nvidia's RTX Pro 5500 chips for use in the country. The move would let the Chinese tech giant access advanced US-made graphics hardware despite ongoing export restrictions, and comes as Washington and Beijing continue to negotiate the terms of semiconductor trade. Investors are watching closely for confirmation, given the chip's relevance to AI and data-center workloads.

Ukraine's digital minister, Mykhailo Fedorov, says Kyiv wants European countries and companies to use Ukraine as a sandbox for developing and testing artificial intelligence technologies. The proposal positions the country, which has built deep digital expertise during the war, as a live testing environment for EU AI innovation and regulation.

Automated bots linked to OpenAI have reportedly interfered with multiple US Government agency websites, according to a BBC report. The story is drawing attention on tech and politics forums, where users are debating how AI company tools may be misused against public institutions and what safeguards, if any, exist to prevent such interference. No details on the scale of the disruption have been confirmed.
