At its Windows and Surface event in San Francisco on October 7, Microsoft announced that Meta's Muse personal AI agent is coming to Windows as a native app. Pavan Davuluri, Microsoft's executive vice president of Windows and Devices, said Muse for Windows would arrive "coming soon" with MXC integration — a notable move from a company that is simultaneously pushing its own Copilot agent.

On October 7, OpenAI began rolling out GPT-6 across ChatGPT, starting with Plus, Pro, Business, and Enterprise users and expanding to Free and Go tiers the next day. The audience is enormous: OpenAI says more than 1.2 billion people use ChatGPT each week. Paid tiers run GPT-6 Sol; free users get GPT-6 Luna, both tuned for everyday conversation.

Washington just put AI companies to work for science — on an unprecedented scale.

At the White House's "Science: A New Golden Age" summit on October 8, the Trump administration announced that eleven technology companies had committed $2.4 billion in AI tools and compute credits to the Genesis Mission, the federal initiative using AI to accelerate scientific discovery across energy, health, space, and national security.

The race to Wall Street between the two biggest AI labs is becoming a race against the clock — and Anthropic is sprinting while OpenAI walks.

According to reporting from the Motley Fool and Reuters, Anthropic could begin marketing its initial public offering as early as the week of November 9, with trading potentially starting before Thanksgiving. The targeted valuation approaches $2 trillion, which would make it the largest IPO in history, clearing the bar set by SpaceX's June 2026 listing at roughly $1.78 trillion.

Washington just took its biggest swing yet at Big Tech's favorite immigration pipeline.

Chinese AI startup DeepSeek is closing in on one of the largest private financings in the history of the AI industry. Bloomberg reported this week that the company is set to raise at least 80 billion yuan — roughly $11.9 billion — with the final tally possibly reaching 100 billion yuan, as it builds a war chest ahead of a domestic initial public offering. Reuters confirmed the outline of the deal with a person familiar with the matter, though the agency noted it could not independently verify the figures and that DeepSeek, Tencent, and CATL did not respond to requests for comment.

Nvidia is circling the open-source coding world — and it already owns a seat at the table.

The money funding America's AI buildout is increasingly coming from Europe.
