CVAI London: EU Sovereignty, Compute Crunch, Anthropic Buzz
The mid-year Cerebral Valley AI Summit in London (published 2026-06-25) gathered model providers, investors, and AI application leaders. An anonymous survey of 57 attendees found most believe the AI sector is in a bubble but do not expect it to burst this year; attendees expressed strong preference for Anthropic as the most desirable private unicorn and a plurality said they would short OpenAI. Speakers highlighted European sovereignty concerns (including Cohere’s ties to Europe and a Cohere merger with a German model provider), persistent global GPU/compute shortages, and debate over agent form factors and utility. Founders were advised to focus on deep domain expertise and underserved verticals (audio, vision, video, consumer apps). The coverage underscored industry sentiment, compute constraints, and investor positioning ahead of further consolidation and commercialization of foundation models.
Industry conference captured current market sentiment (bubble views), investor preferences (Anthropic traction vs OpenAI skepticism), and operational constraints (global GPU/compute shortages) that affect AI commercialization and downstream AdTech/MarTech use cases.

Tech Investors Face Summer AI Market Uncertainty
Rising valuations, volatile markets and political backlash are creating a nervous environment for tech and AI investors this summer. The piece highlights bubble warnings from the Bank for International Settlements, increased margin trading, and concerns from prominent investors and executives. Several specific developments are noted: Amazon dropped distribution of an almost-completed OpenAI movie (Neon has since acquired it); Together AI and German drone maker Quantum Systems raised major funding rounds; OpenAI has discussed donating a 5% stake to a U.S. sovereign fund; Meta and xAI are entering the business of selling compute; and Anthropic’s co-founder Tom Brown reportedly brokered a truce with the U.S. government. The article also flags growing political risk around data centers, the persistence of FOMO among investors, and continued strong revenue growth at leading AI firms.
Anthropic Access Restricted as AI–VC Market Concentrates
U.S. government export controls that blocked worldwide access to Anthropic’s high‑capability models (Fable 5 and Mythos 5) followed reports that Amazon CEO Andy Jassy told Treasury Secretary Scott Bessent and other officials that Amazon researchers had used Anthropic’s Claude Fable 5 to obtain information that could be repurposed for cyberattacks. News outlets including the Wall Street Journal, The Information and Reuters reported Amazon — a major Anthropic investor — communicated security concerns prior to the government action. David Sacks, co‑chair of the President’s Council of Advisors on Science and Technology, said a trusted partner reported a jailbreak and claimed Anthropic CEO Dario Amodei declined to de‑deploy or fix the issue. Anthropic subsequently contested the government directive as it temporarily restricted model access globally.
