Nscale tells investors it has $103 billion under contract

Reuters reported, citing The Information's account, that British AI infrastructure company Nscale showed investors a pitch for a possible 2027 public offering. The pitch forecasts about $2 billion in revenue next year and $15 billion in 2029. It says Nscale has $103 billion in contracted revenue with customers including Microsoft, OpenAI, and Anthropic. That number is a long-term contract claim, not collected sales.

Nscale did not respond to Reuters's request for comment. One publication described a private investor pitch. The figures are still a company forecast, not independently verified revenue.

Uber plans to cut 3,300 jobs as robotaxi rivals close in

Bloomberg reported that Uber plans to eliminate about 3,300 corporate jobs. Reuters and The Guardian cited that report. The cuts equal roughly 10 percent of Uber's global workforce. An internal memo called the move a reset to remove layers and speed decisions. The cuts are Uber's largest since 2023. Uber is also spending to compete in autonomous driving and delivery.

Uber did not immediately comment to Reuters. The memo tied the cuts to management structure and speed, not directly to AI. Robotaxi competition is business context here, not Uber's stated reason for the layoffs.

Justice Department backs OpenAI on fair use

The Justice Department urged a New York federal judge to accept OpenAI's fair-use argument. OpenAI argues that training models on copyrighted news articles is fair use. In a September 1 statement of interest, the department addressed the publishers' consolidated case.

The New York Times said the administration is siding with large AI companies at creators' expense. The Times argued that model developers should pay for protected work. Judge Sidney Stein still has to apply the four-part fair-use test to the facts before him.

New York City bars younger students from generative AI

New York City barred public school students below high school from using generative AI during the school day. High-school students can use only tools their schools provide. The city also capped device-based instruction at one hour a day for kindergarten through eighth grade. It extended its smartphone ban across elementary and middle schools. Officials said the rules are meant to protect independent thinking and human connection.

The policy draws a clear age line, but a huge school system still has to enforce it. Teachers need useful non-AI software, enforcement rules, and a way to separate banned generation from ordinary search, accessibility tools, and tutoring tools.

Anthropic and Commerce restart talks after Pentagon dispute

Commerce Secretary Howard Lutnick said the Trump administration is in active talks with Anthropic. He said the administration wants the company back on the government's right side after a public dispute over military uses of its models. Lutnick said Anthropic has worked closely with officials on cyber tools. He contrasted Anthropic with OpenAI, which he said gave the government what it asked for. The comments suggest a thaw, not a settlement.

Lutnick's remarks and the reports do not show what Anthropic has agreed to change. The core dispute involved limits on autonomous weapons and domestic surveillance. That makes the missing contract language more important than the warmer tone.

AI-designed proteins delivered RNA in animal tests

Researchers built more than 100 synthetic RNA carriers from natural functional domains and protein assemblies designed by generative models. Their best design, STV-C8, transferred RNA more efficiently than the virus-like particles and lipid nanoparticles tested in cell culture. The team tracked delivery in mice. The team also used the carrier to remove a disease-related section of the dystrophin gene in pig muscle cells.

This is early laboratory and animal work, not a human treatment. After intravenous dosing, the carrier delivered RNA mainly to mouse lungs. The team still has to improve targeting and study how the carrier moves through the body.
