That round was said to be led by Situational Awareness, an AGI-focused fund founded by former OpenAI researcher Leopold Aschenbrenner, and backed by Stripe&#8217;s Collison brothers, former GitHub CEO Nat Friedman, and the AI investor and entrepreneur Daniel Gross.<\/p>\n\n<p class=\"wp-block-paragraph\">Talks were apparently still ongoing for this round in February, at least with Google, which was considering kicking in $100 million to the round, <a href=\"https:\/\/www.wsj.com\/tech\/ai\/google-is-exploring-ways-to-use-its-financial-might-to-take-on-nvidia-0fbadc84\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">The Wall Street Journal reported.<\/a><\/p>\n\n<p class=\"wp-block-paragraph\">There&#8217;s good reason for the hype over Fluidstack. In November, Anthropic announced that it had <a href=\"https:\/\/techcrunch.com\/2025\/11\/12\/anthropic-announces-50-billion-data-center-plan\/\">signed a $50 billion deal <\/a>with the startup to build data centers custom-designed for its needs in Texas and New York. Unlike hyperscalers like AWS, which serve all kinds of computing needs, Fluidstack&#8217;s infrastructure is built specifically for AI.<\/p>\n\n<p class=\"wp-block-paragraph\">The deal was a huge vote of confidence for Fluidstack, a company that was relatively unknown in the U.S. Anthropic primarily uses AWS and Google Cloud to serve Claude (though it also has a partnership with Microsoft to supply Claude to that software giant&#8217;s customers). But just like rival OpenAI, <a href=\"https:\/\/techcrunch.com\/2026\/03\/28\/anthropics-claude-popularity-with-paying-consumers-is-skyrocketing\/\">Anthropic is growing so fast <\/a>that it needs more capacity, and this deal gives Anthropic more control over its own cloud infrastructure.<\/p>\n\n<p class=\"wp-block-paragraph\">This partnership is so significant to the startup that Fluidstack &#8212; which was spun out of Oxford and had been a rising star in Europe&#8217;s AI scene &#8212; relocated its headquarters from the U.K. to New York. Last month, it also pulled out of a <a href=\"https:\/\/www.bloomberg.com\/news\/articles\/2026-03-18\/fluidstack-drops-out-of-marquee-10-billion-ai-project-in-france?embedded-checkout=true\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">key \u20ac10 billion AI project in France<\/a>, Bloomberg reported, to focus on U.S. opportunities.<\/p>\n<div class=\"wp-block-techcrunch-inline-cta\">\n\t<div class=\"inline-cta__wrapper\">\n\t\t<div class=\"inline-cta__logo\">\n\t\t\t<svg aria-hidden=\"true\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"41\" height=\"20\" fill=\"none\" viewBox=\"0 0 41 20\"><path fill=\"#fff\" d=\"M0 0v6.452h7.097V20h7.097V6.452h6.451V0zM27.742 13.548V6.452h-7.097V20h20v-6.452zM40.645 0H27.742v6.452h12.903z\"\/><\/svg>\t\t<\/div>\n\t\t<div class=\"inline-cta__flag\">Techcrunch event<\/div>\n\t\t<div class=\"inline-cta__content\">\n\t\t\t<div class=\"inline-cta__header-container\">\n\t\t\t\t<div class=\"inline-cta__header-container-desktop\">\n\t\t\t\t\t\t\t\t\t\t\t<h3 class=\"inline-cta__header has-h-5-font-size\">Meet your next investor or portfolio startup at Disrupt<\/h3>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<h4 class=\"inline-cta__subheader\"><br>Your next round.
