On June 1, Anthropic filed confidentially for a US IPO at a $965 billion valuation, with a revenue run rate approaching $47 billion. Every AI publication covered it. What they mostly missed: in the same seven-day window, four quantum computing companies raised a combined $961 million from European institutional investors, two unrelated founding teams built purpose-built payment rails for AI agents to transact autonomously, and a Chinese AI lab that had never taken outside capital broke its own founding principle in its first-ever funding round.
This is not a recap of the Anthropic IPO. That story is well-reported. This is everything else that happened in the week of June 1.

Europe's Quantum Week That Got Buried
Four quantum computing companies raised money in seven days. Two were from Oxford. One was Finnish. One was French. None coordinated their timing. Together they pulled in $961 million, and the milestone passed almost without comment in the generalist press.
Oxford Quantum Circuits raised $350M in an oversubscribed Series C to scale its quantum-AI data-centre platform. The same week,
OQC (also Oxford-based, also building superconducting qubits) closed its own $350M Series C, described by OQC as Europe's largest ever private quantum funding round, led by Bullhound Capital with backing from the British Business Bank, Magdalen College Oxford, and a broad set of institutional investors.
IQM of Finland upsized its PIPE to $146M as it prepares a dual listing on Nasdaq and Nasdaq Helsinki, which would make it the first European quantum hardware company trading on both exchanges. And
Quobly of Grenoble raised a $115M Series A for its sapphire-based superconducting qubit approach.
