The Stakes

Amazon’s Lab Stakes: Anthropic $238.7 Billion, OpenAI $50 Billion

Amazon’s quarterly report carries its Anthropic notes and shares at $238.7 billion, by our sum, against $18 billion put in, and records $50 billion invested in OpenAI.

“Additionally, we entered into a financing arrangement to make available to Anthropic an aggregate facility not to exceed $20.0 billion that will expire 30 months after an Anthropic liquidity event, including an initial public offering (‘IPO’). At inception, there is no amount available to be drawn against and as we reach certain delivery milestones of compute capacity under the amended commercial arrangement, amounts under this facility are made available for Anthropic to draw upon at its discretion. Draws against the facility will be in the form of new Anthropic convertible notes or, after an IPO or other liquidity event and subject to our ownership cap, Anthropic common stock, which will be issued to us in exchange for cash.”

Four AI Makers Back One ‘No Training’ Signal

Google, OpenAI, Microsoft and Anthropic announced support for a shared robots.txt signal against AI training, Microsoft from Feb. 1, 2027; it is a preference, with no payment attached.

Google, OpenAI, Microsoft and Anthropic announced support on Friday for a shared signal in a website’s robots.txt file expressing a preference against the use of its pages to train generative AI models. Until now, OpenAI said, a site that wanted to refuse had to identify each company’s crawlers and keep separate rules for every one.

It is a preference, not a license. Microsoft wrote that its new preferences “do not establish licensing or payment arrangements,” and the standards draft behind the signal lets private agreements override what a site has said. For publishers, one shared rule could do the work of several. Nothing in it pays them.

xAI’s Turbines Are Not ‘Mobile,’ Judge Rules; Suit Proceeds

A judge refused to dismiss the NAACP’s suit over xAI’s Mississippi turbines, at least 495 megawatts by the complaint’s count, ruling they are not permit-exempt ‘mobile sources.’

A federal judge in Mississippi refused on Friday to dismiss the NAACP’s Clean Air Act suit against xAI, ruling that the gas turbines powering its Colossus 2 data center are not “mobile sources” exempt from air permits. Judge Debra M. Brown also rejected xAI’s arguments that the NAACP could not sue for its members and that citizen suits are unconstitutional.

The ruling decides only that the case goes on. On a motion to dismiss, a court takes the complaint’s allegations as true and makes no findings, and the NAACP’s request to shut the turbines down while the case proceeds still awaits a decision.

The Week Ahead

Intel Has Its Worst Day Since 1974; Chips Follow

Intel fell 28.58 percent Friday, its worst day since 1974 by CNN’s count; the chip index lost 7.20 percent before AMD, Qualcomm and Arm report next week.

Intel’s shares fell 28.58 percent on Friday, to $65.76, “its worst day since 1974 and second-worst day on record,” CNN reported, the day after the company forecast a weaker fourth quarter and blamed costly memory for a shrinking PC market. Some 455.6 million shares changed hands, against 134.2 million on Thursday.

Other chip makers fell with it: the PHLX Semiconductor index lost 7.20 percent, and AMD, Qualcomm and Arm, which all report their own quarters next week, fell 10.88, 11.12 and 9.97 percent. The Nasdaq Composite fell 2.86 percent and the S&P 500 1.82 percent, “each suffering their worst day since June,” CNN reported.

Analysis

October Split the AI Trade, Hardest on Hardware

The chip index lost 15.36 percent in October; Alphabet and Meta, whose quarterly free cash flow turned negative, fell 15 to 19 percent while Microsoft and Apple rose.

October split the stock market’s AI trade, and the split was hardest on hardware. The makers of AI hardware and the companies that rent it out fell furthest: Intel lost 45.30 percent over the month, CoreWeave 37.02 percent and Nebius 34.65 percent, and the PHLX Semiconductor index 15.36 percent.

Among the largest technology companies, Alphabet and Meta, whose quarterly free cash flow turned negative this year, fell 18.67 and 15.19 percent, while Microsoft and Apple rose 1.76 and 3.49 percent. Microsoft’s cash from operations exceeded its spending on property and equipment by $18.6 billion last quarter. Investors and strategists quoted by CNN gave cash as the reason.

One Month

The change in closing price over October, from Sept. 30 to Oct. 30, 2026, the month’s last trading day, for five indexes and a selection of the companies in the AI trade, worst to best.
