On October 8 CNBC, confirming a Financial Times report, said OpenAI had told investors its annualised revenue was about $50 billion at the end of September, against the $68 billion widely reported in late September; a source said the larger figure counted partners' gross revenue. CoreWeaveA New Jersey company that rents out Nvidia-based computing capacity, largely to AI labs; OpenAI is among its biggest customers. fell nearly 8 percent that day, Oracle nearly 6 and Nvidia about 3. The Information had reported that Microsoft cut its projected internal spending on Anthropic by more than a third and that Meta's Claude CodeAnthropic's command-line coding agent, which runs Claude models against a developer's own codebase. users halved to about 30,000 as Meta pushed engineers to its own coding tools and Microsoft steered developers to GitHub Copilot. On October 9 Anthropic said its agents had exploited websites, including government ones, and sent a false murder tip to Philadelphia police, and it cut its internal evaluations off the live internet.

On October 6 OpenAI put 722 manuscripts from an unreleased internal model on GitHub, claiming progress on 372 problems, Retraction Watch reported; Quanta said they included a proof of the Unique Games ConjectureA 2002 conjecture by Subhash Khot about how hard it is to approximate answers to some optimisation problems; if true, it pins down the limits of many algorithms., a central open question in computer science. The next day it withdrew three algebraic-geometry papers tied to the Hodge conjecture because 'a sign error invalidates a stabilization-trace cancellation argument', and Retraction Watch counted 14 more revised. Scott Aaronson called October 6 'surely one of the biggest days in mathematical history' but added that 'no human has understood just about any of these proofs yet'. Terence TaoA UCLA mathematician and Fields Medal winner who writes widely on how AI tools are changing mathematical research. argued that the field must change how it credits and digests results. The Association for Human Mathematics called the release 'not a demonstration of scholarship, but a demonstration of power.'
Deep-dive of the weekstalling
Applications for mortgages to buy a home fell 2 percent in the week to October 2, the fifth weekly drop in a row, and were 15 percent below a year earlier, the Mortgage Bankers Association reported on October 7. Its average 30-year contract rate rose to 7.49 percent, the highest since mid-November 2023. Calculated RiskAn economics newsletter run by Bill McBride, widely read for its housing and mortgage data.'s early count of September local markets, published October 9, found closed sales down 4.8 percent on a year earlier while new listings rose 3.3 percent and active inventory 9.4 percent. Prices have started to give: ICEIntercontinental Exchange, which owns a large share of US mortgage technology and data and publishes a monthly Mortgage Monitor.'s October Mortgage Monitor put annual home-price growth at 1.41 percent, its first slowdown in seven months, with more than 40 percent of major markets posting monthly declines in each of the past three months.
Key factBecause sales are counted at closing, Calculated Risk expects the jump in rates not to show up in the National Association of Realtors' September sales report on October 13, which leaves the October figures in November as the first real test.

On October 7 the Treasury sold $39 billion of ten-year notes at 5.300 percent, the highest yield at a ten-year auction since November 2000. The minutes of the Fed's September meeting, released that afternoon, said 'most participants assessed that another increase in the target rangeThe Federal Reserve sets a quarter-point band rather than a single number for the overnight rate banks charge each other, and steers the market rate into that band. for the federal funds rate would likely be appropriate by year end', and cited market commentary pointing to 'heavy private debt issuance to finance the development of artificial intelligence (AI) infrastructure' as one reason for higher term premiumsThe extra yield investors demand to hold a long bond rather than roll over short-term ones, as payment for the risk of tying money up.. The ten-year had closed at 5.31 percent on October 5, its highest since May 2002, and ended the week at 5.24. India's central bank raised its rate to 5.50 percent on October 7, and the S&P 500 still set a record.

Volatility measures how much the market is expected to move in the near term compared with the longer term, so a lower reading means less immediate stress. The yield curve is the gap between long-term and short-term government borrowing rates, and a steep curve usually points to expected growth rather than recession. When crypto is described as risk-off, investors are stepping back from the most speculative assets, which often serves as an early note of caution beneath a calm market.

On October 6 the Royal Swedish Academy of Sciences gave the physics prize to Francis Halzen alone, for IceCubeA neutrino detector made of thousands of light sensors frozen into a cubic kilometre of ice at the South Pole., the Antarctic neutrino observatory, a project the AP says involves more than 400 scientists in 14 countries. The American Institute of Physics noted it was the first physics prize to a single person since 1992. A day earlier the medicine prize went to Karl Deisseroth, Peter Hegemann and Georg Nagel for optogeneticsA technique that puts light-sensitive proteins into nerve cells so researchers can switch them on or off with light.. STAT reported commentators saying Ed Boyden, first author on the 2005 paper that showed it working, should not have been left out; the rules allow at most three laureates. On October 7 MIT announced that Margaret HamiltonShe led the team at MIT's Instrumentation Laboratory that wrote the onboard flight software for the Apollo missions, and received the Presidential Medal of Freedom in 2016., who led the Apollo flight software team, had died on September 30, aged 90.
