Nvidia, the world’s most valuable company, is in advanced talks to pump $500 million (£400m) into Wayve, a UK-based self-driving car start-up. The new funding commitment was unveiled during an event in London coinciding with President Trump’s state visit, where Nvidia pledged £2bn in UK start-up investments spanning AI and fintech. Beneficiaries include digital bank Revolut and video AI company Synthesia. Wayve, founded in London, is developing AI-powered systems to help vehicles interpret surroundings and navigate without human input. For the UK, the flurry of announcements highlights its growing status as a hub for AI investment, even as it navigates challenges around regulation, skills and infrastructure.
