OpenAI has closed the first 11 billion dollars of its latest funding round, at a valuation of 1.25 trillion dollars, Bloomberg News reported on Friday, citing people familiar with the matter. Reuters carried the report on Friday evening, November 6. The money has been wired, according to the reporting, but the round itself is not finished, and OpenAI declined to comment.

A research system built by Physical Superintelligence, a laboratory known as PSI, has produced a proof of the Aaronson-Ambainis conjecture, a central open problem in quantum computing that had stood since 2008. PSI announced the result on Friday, saying that its internally developed system, running instances of a non-public Anthropic model on PSI's own infrastructure, had a complete proof during the third day of the run. The proof was then accepted by Lean, a proof assistant that checks every logical step by computer.

The artificial intelligence trade suffered its sharpest reversal of the year on Thursday, November 5, as investors reassessed what this week’s midterm elections mean for the data center buildout that has powered the boom. The Nasdaq Composite fell 5.52 percent to close at 24,315, its worst session since April 2025, and finished firmly in correction territory, down as much as 14 percent from its all-time high reached only a month ago. Reuters estimated that some 2 trillion dollars was wiped off the Nasdaq’s market value in a single day.

Anthropic is now improving its AI models at about twice the pace it managed before late 2025, and most of that acceleration appears to come from the company using AI to help build AI. That is the central finding of an independent assessment published on November 5 by METR, a nonprofit that evaluates frontier AI systems, after its staff spent eleven weeks examining Anthropic's internal research process.

Meta has acquired Conductor, a young artificial intelligence startup whose software lets developers run several coding agents at once, each working on a separate part of a project in its own workspace. Meta confirmed the acquisition to TechCrunch but declined to comment further, and the financial terms were not disclosed. The deal was first reported by Axios, and Conductor announced it on its own blog on Wednesday.

The artificial intelligence buildout met its clearest political test yet on Tuesday, and voters were not persuaded. In 41 local ballot measures across 10 states on November 3, voters backed restrictions on data centers or rejected proposals that would have helped them get built in 40 cases, according to an analysis by Ballotpedia and results compiled by CNBC. The results, still unofficial, covered bans, moratoriums, zoning changes and requirements for public votes on large projects.

OpenAI has published the results of a striking security experiment: an autonomous pipeline powered by an upcoming cyber model scanned the Linux kernel, proved hundreds of vulnerabilities were real, built working exploits for them, and drafted a patch for each one. In a single mid-October run, the system produced 948 distinct local privilege escalation vulnerabilities, the kind of flaw that lets an ordinary logged-in user gain root access, the highest level of control on a Linux machine.

OpenAI announced on Wednesday, November 4, that it will acquire Pierre Computer Company, a low-profile developer tools startup whose software already runs inside Codex, its AI coding platform. The financial terms were not disclosed. The deal is subject to customary closing conditions, including regulatory approvals, and the two companies will remain separate and independent until it closes.

Google has given schools a new set of controls over artificial intelligence in the classroom,. In a blog post on November 3, Chris Phillips, Google's vice president and general manager of education, said access to Gemini, Gemini Notebook, Gemini in Classroom and Google Search will be entirely off for K-12 student accounts until school administrators explicitly turn them on.

CrowdStrike used its Fal.Con Europe conference in Barcelona on Tuesday, November 3, to make three connected moves on AI agent safety. The company introduced an AI Kill Switch inside Falcon Guardian, and it signed agreements to acquire two AI security startups, Fiddler AI and Dreadnode. Together, the announcements cover testing an agent before it ships, watching it in production, and stopping it when it goes off course.
