Ireland reconsiders its nuclear ban as data centres eat a quarter of the grid

Ireland is Europe's data-centre capital, and it's running out of cheap ways to power the AI boom. Lawmakers are now reopening a debate the country closed in 1999, when it banned nuclear power — a sign of how hard the AI buildout is bending national energy policy in the world's smaller grids. Ireland is reconsidering its 1999 ban on nuclear power, driven by data centres that now account for about a quarter of the country's electricity use.

Velaura AI raises $110M at $1B+ for low-power chips

The AI build-out keeps slamming into a wall cash cannot move: watts. A Santa Clara chip shop just got priced like it already found a way around it. Velaura AI closed a $110 million Series A on Tuesday at a valuation of more than $1 billion, selling investors on silicon that squeezes more AI work out of the power budget they already have. Seligman Ventures led the round. Capricorn Investment Group and Prosperity7 Ventures came in as new money.

Jais 2 ships: a 70B open Arabic LLM at 2,000 tokens per second

Two stories today show where the field's energy is going: open models getting culturally specific, and a hard, numbers-backed look at the "skills" layer everyone is bolting onto their agents. Jais 2 is here: a 70B open-weight Arabic model that serves 2,000 tokens a second. Inception (a G42 company), Cerebras, and MBZUAI released Jais 2, which they describe as the largest open Arabic-centric LLM trained from scratch, alongside an 8B variant.

Fermi names nuclear veteran Lee McIntire as CEO

Two stories from the AI buildout's two most contested frontiers landed Wednesday: the power side and the data side. Fermi, the company behind the nuclear-powered Project Matador campus in Texas, ended its three-month CEO search by hiring a veteran of the nuclear industry, and publishers gained a new weapon in the fight against AI scrapers — a font that poisons training data while staying perfectly readable to humans. Fermi, the AI data center developer behind the nuclear-powered Project…

Nvidia invests up to $3B in power firm behind Stargate

The AI buildout's newest bottleneck is the grid, and the industry's biggest players are moving accordingly: Nvidia is buying into the electricity developer behind Stargate, Microsoft is fast-tracking its next in-house chip, and an AI notetaker left more than 181,000 meetings exposed. Nvidia has agreed to invest up to $3 billion in Lancium, the Texas power-infrastructure developer behind the Stargate AI campus, according to three people familiar with the deal reported by The Information.

Amazon backs a 7.65 GW gas plant for an off-grid Texas AI campus

The AI power arms race just crossed a new line: Amazon is behind what could become the largest fossil-fuel power plant ever built in the US, and it exists for one customer — Amazon's own AI data centers. Amazon has confirmed it acquired GW Ranch, a site in Pecos County, West Texas, where it plans to build a 7.65-gigawatt natural gas plant to power its first off-grid AI data center campus — a project that state permits suggest could become the single largest source of emissions in the country.
