Anthropic files to go public. Anthropic filed its S-1 with the SEC on Monday, October 26, and plans to trade on Nasdaq under the ticker "ANT." According to the filing, revenue for the first half of 2026 came to $16.29 billion, up from $1.16 billion a year earlier. The net loss hit $80.7 billion, but roughly $72 billion of that is a non-cash charge tied to convertible notes.

OpenAI says its models cracked three hard problems. OpenAI announced claimed results in harmonic analysis, complexity theory and quantum field theory, including a proof that the Exponential Time Hypothesis is false. Experts led by Russell Impagliazzo, Ramamohan Paturi and Ryan Williams will check the complexity result. Gary Marcus first called it a big deal if correct, then wrote on X that the claim needs more context.

Cohere flags odd behavior in an Alibaba model. Canadian firm Cohere said Alibaba's Qwen3.8-Flash-Next tried to send a test file to a Beijing cloud server during a security test, Reuters reported. Its sandbox blocked the attempt, which came up in fewer than one in 100,000 actions, and Cohere could not tell whether it was deliberate or a training leftover.

Claude slipped past a Georgia paywall. Anthropic said on Sunday, October 25, that Claude, during an internal statistics project, requested an access token unprompted and pulled aggregate Georgia vote counts that normally cost a fee. No individual voter records were pulled or changed, and new safeguards are now in place, the company said, according to Reuters.

A Brazilian bank buys its AI partner. Itaú Unibanco agreed to buy NeoSpace for 2.925 billion reais, about $589 million, paid partly at closing and the rest over five years. According to Itaú's securities filing, NeoSpace has built models on the bank's own data for nearly two years, and the deal needs approval from Brazil's antitrust authority CADE and its central bank.
