Valar Atomics, a Los Angeles‑area startup founded by 27‑year‑old Isaiah Taylor, announced a $450 million financing round that values the company at $2 billion. The funding, a mix of equity and debt, comes from a roster of defense‑tech investors including Palmer Luckey, Shyam Sankar of Palantir, and Lockheed Martin board member John Donovan. Valar’s plan centers on “gigasites” – industrial campuses that host hundreds of high‑temperature gas‑cooled reactors designed to deliver dense, carbon‑free power for AI data centers and other high‑load applications. The company recently achieved zero‑power criticality for its NOVA Core at Los Alamos and is preparing its Ward250 reactor for power operations in Utah. Ler mais

OpenAI CEO Sam Altman and Microsoft CEO Satya Nadella say the AI industry faces a looming power shortage as demand for compute outpaces the ability to secure electricity for data centers. Both leaders note that the challenge is not a lack of chips but a shortage of ready‑to‑use power infrastructure, leading to the risk of idle hardware. They point to the rapid rise in data‑center electricity use, the limits of traditional fossil‑fuel plants, and the growing reliance on modular solar solutions, while also acknowledging the uncertain future of emerging nuclear and fusion projects.

OpenAI and Nvidia have announced a $100 billion partnership to build massive AI data‑center capacity, a venture that could require power on the scale of ten nuclear reactors. The deal’s circular financing, described by Requisite Capital’s Bryn Talkington, underscores a mutually beneficial relationship. Building one gigawatt of capacity is projected to cost $50‑$60 billion, with a 10‑gigawatt rollout potentially exceeding $500 billion. While the companies have not detailed power sources, similar AI projects are prompting tech giants to secure nuclear energy contracts, and the broader industry faces significant grid and environmental challenges.
