Anthropic's alliance with pope on AI harms: all in good faith or'Vatican-washing?' Experts say AI firm's engagement with Vatican risks creating'feelgood' discourse that lacks critical examination Why did Anthropic's founder sit beside the pope during a warning about AI? In the first major written teaching of his papacy, Pope Leo XIV took artificial intelligence to task. At a ceremony honoring the holy teaching the day of its release at the Vatican, the pope was flanked by an unusual guest speaker: Anthropic co-founder Chris Olah, one of the people behind the AI boom so worrying Leo. Olah's presence raises a key question: how could the Catholic church and the world's most valuable AI startup work together, when Anthropic's technology may bring about the future Leo is warning against? Leo's encyclical discusses at length the preservation of the dignity of humans' work as it comes under threat from AI - but major AI companies, including Anthropic, aren't prioritising these concerns, says Pete Furlong, senior manager of policy and research at Center for Humane Technology, a nonprofit advocating for accountability around AI. "All of these companies are building technology that is designed to replace people," Furlong says.

Pope Leo XIV may not be able to disarm AI, but he's got the attention of the industry. For one thing, Olah is an atheist who at 15 rejected his evangelical Christian upbringing. As a Thiel fellow, he accepted a grant from the guy who thinks that anyone who slows down AI progress is a legionnaire of the antichrist . Olah is also a cofounder of Anthropic, a leading AI company reportedly about to go public with a nearly trillion-dollar valuation. Olah commented on the oddness in his remarks at the Vatican.

How a new extraction process could unlock the world's lithium A new method for extracting lithium could cut costs and emissions from one of the world's most important materials for EVs and energy storage. The technique uses a weak acid to dissolve silicate minerals. That frees not only the lithium but also other useful materials, including alumina and silica. "At scale, we believe this will be the lowest-cost way of sourcing lithium in the world," says Yet-Ming Chiang, an MIT professor who co-authored a study of the process published yesterday in . Startup Rock Zero is already working to commercialize the research.

Anthropic has usurped OpenAI as the world's most valuable artificial intelligence startup, soaring to a $965bn valuation ahead of expected public listings by the rival firms. Anthropic, the maker of the Claude family of chatbots, said on Thursday that it had raised $65bn from private investors after a fundraising round led by Altimeter Capital, Greenoaks, Dragoneer and Sequoia Capital. "This funding will help us serve the historic demand we are experiencing, stay at the research frontier, and bring Claude to more of the places where work happens," Anthropic's Chief Financial Officer Krishna Rao said in a statement. Altimeter Capital CEO Brad Gerstner hailed the adoption of Claude among the "world's most demanding organisations" as evidence of Anthropic's command in the field. "This momentum positions Anthropic to lead the next phase of AI innovation and capture the enormous opportunity ahead," Gerstner said.

Anthropic's rise came by doubling down on delivering generative artificial intelligence to enterprise clients rather than general users. Artificial intelligence company Anthropic said Thursday it had raised $65 billion in a new funding round that values the Claude maker at $965 billion, more than its archrival OpenAI, the maker of ChatGPT. The latest fundraising round confirms Anthropic's place as one of the most significant players in AI, with the startup led by Dario Amodei having drawn fans for its coding powers and state-of-the-art models. Anthropic's rise came by doubling down on delivering generative AI to enterprise clients rather than general users, the path initially chosen by OpenAI.

Anthropic reaches valuation of $965bn, beating OpenAI to become world's most valuable AI firm Claude's parent company's $65bn in latest funding round underscores vast sums of money still flowing into industry Anthropic, the AI firm behind the Claude chatbot, announced on Thursday it had raised $65bn in funding to value the company at $965bn post-money. The move makes Anthropic the world's most valuable AI startup, eclipsing its competitor OpenAI. The deal marks an exceedingly successful period of growth for Anthropic, which was once considered to be a smaller player in the global AI arms race.

PCWorld reports that Anthropic's Claude Opus 4.8 focuses on improving AI honesty by teaching the model to admit when it lacks information. The model achieved near-perfect scores in honesty benchmarks for coding questions and exhibited evaluation awareness during testing. Opus 4.8 represents a significant step forward in making AI systems more transparent about their knowledge limitations and uncertainties. Honesty is a key sticking point with even the most powerful LLMs. It's not so much that they're intentionally lying to you; instead, they'll confidently tell you things they're not 100 percent (or even 50 percent) sure about. With Opus 4.8, its latest Claude model, Anthropic says it's made Claude more honest about telling you what it doesn't know, or if it has a low level of confidence in what it's telling you. Released Thursday, Claude Opus 4.8 is Claude Mythos Preview, Anthropic's new "frontier" model that's so powerful, only a handful of "trusted partners" have been allowed to test it for security reasons.

Solar and battery company Solv Energy went public in February, hitting a $6 billion valuation. X-energy, which builds small modular nuclear reactors, followed at $11.5 billion. Then came geothermal company Fervo Energy, reaching a market cap of about $12.4 billion. All three have been IPO success stories.

Trajectory is betting the rapid iteration cycle that supercharged vibe-coding can help all kinds of companies build AI products that learn continuously. Trajectory founders, Ronak Malde (left), Michael Elabd(center), and Arjun Karanam (right). A group of AI researchers who previously worked at Google DeepMind, Apple, OpenAI, and Meta Superintelligence Labs announced on Wednesday they're launching a new startup called Trajectory, which aims to help companies regularly improve their AI products by training on real-world user interactions. Trajectory wants to build a platform for AI that can learn continuously, a capability that researchers have long held up as a major barrier to further AI progress. OpenAI, Google, and Anthropic have found success training increasingly capable versions of AI models, especially for domains such as coding, math, and science.

Pope Leo XIV attends the presentation of his first Encyclical Letter Magnifica Humanitas in The Vatican on May 25, 2026. Pope Leo XIV attends the presentation of his first Encyclical Letter Magnifica Humanitas in The Vatican on May 25, 2026. Over the past year, Pope Leo XIV and President Donald Trump have clashed several times in the press, including on the Iran War, nuclear weapons, and immigration. On Monday, Leo potentially opened a new front: AI. Leo's new encyclical --a 42,300-word open letter to the world's 1.4 billion Catholics about preserving dignity in a tech age--never mentions Trump at all.
