Volta Infrastructure Holdings, a London-based start-up incorporated in January, has agreed a $10 billion data centre deal with Anthropic and raised funding from backers including Nvidia at a $2.4 billion valuation. Volta said Azora had established a $5 billion AI infrastructure programme to finance AI factories that Volta will develop. It also comes amid growing questions about the scale of investment being poured into AI data centres by the technology sector. Ofgem said demand connection applications had risen from 41 gigawatts to 125GW in under a year, with data centre projects accounting for at least 80GW. OpenAI paused its Stargate UK data centre project in April, citing British industrial energy prices and uncertainty over copyright rules, and said it would proceed once “the right conditions” allowed.
