Alphabet suffers worst drop since IPO, while Azure rises on first disclosure

Nothing in this morning's earnings cast doubt on AI demand. Alphabet's Google Cloud grew 103% year on year to $30.7 billion. Microsoft disclosed Azure revenue as a dollar figure for the first time: $33.165 billion (+48%). The market punished not demand but cash and supply. Alphabet's search and related revenue was $63.4 billion, short of expectations of about $65 billion. Free cash flow was −$9.1 billion, and the stock fell roughly 12–13% intraday on October 29, reportedly its worst drop since its 2004 IPO. Microsoft said capital expenditures came in below expectations because deliveries of external GPU capacity were delayed. The same dynamic sits behind both companies' diverging fortunes: what now constrains the AI build-out is the ability to keep cash flowing, and whether rented GPUs actually arrive.

On the lab side, the common theme was openness. Mistral released the weights of a 1T model two days ahead of schedule. OpenAI made public the monitoring system that outside researchers had attacked, and rewrote its Model Spec.

Earnings: cloud doubles, cash goes negative

According to its 8-K, Alphabet's revenue was $127.6 billion (+25%), slightly below expectations. EPS was $2.12, down from $2.87 a year earlier. The company booked a net loss of $8.7 billion on equity valuations, and on the earnings call it attributed most of an $8.2 billion unrealized loss to its SpaceX stake. Google Cloud's backlog stands at $561 billion, about 55% of which will be recognized as revenue within 24 months. Capital expenditures of $51.4 billion came in below expectations (about $55 billion to $56 billion), yet free cash flow still turned negative. The company kept its 2026 capex outlook at $195 billion to $205 billion, and said only that 2027 spending would "increase significantly." The circulating figure of "$300 billion in 2027" appears neither in the filing nor on the call. The faster cloud grows, the more cash goes out up front, and search, which funds that spending, slowed. The market disliked the combination.

Microsoft's commercial remaining performance obligation (RPO) was $677 billion (+73%). Capital expenditures, including finance leases, were $45.2 billion, below expectations of about $50.7 billion. CFO Amy Hood said some deliveries of external capacity expected in the January–March quarter had slipped. In other words, GPUs it planned to rent from neoclouds have not arrived. Capex for the October–December quarter is expected to exceed $50 billion. Hood also said "roughly $170 billion for the calendar year," though reports differ on which calendar year she meant. Microsoft shares rose 2–3% intraday. Meanwhile, before the open on October 29, CoreWeave fell 6%, Nebius 6.9% and IREN 4.9%, halting their recovery from the previous days. Those two companies report on November 9 and 10.

Fears that AI is eating software also spread. ServiceNow raised its target for AI annual contract value to $1.7 billion and said usage of agentic AI had grown 13-fold. Even so, its outlook for current remaining performance obligation (cRPO) fell short of expectations, and the stock dropped 19–24%. Caterpillar fell 9–12% after keeping its full-year outlook unchanged, even though its power segment grew 30% on data center demand, a crack in AI power stocks. The Nasdaq was down 1.57% intraday (around 18:51 UTC, not the close). Third-quarter GDP grew 3.4%, making the macro backdrop neutral or a mild tailwind. Most of the decline came from company-specific AI and software news.

Samsung's final July–September results showed operating profit of 107.4 trillion won, of which the semiconductor division contributed 106.5 trillion won. It did not disclose HBM revenue, so whether it overtook SK hynix cannot be confirmed from primary sources. On its call, the company said its 2027 HBM supply was sold out (secondhand report). Separately, Bloomberg reported that Marvell is in talks to buy optical-components maker Lumentum for more than $8 billion. Reuters reported that the US Justice Department is examining NVIDIA's $12.93 billion acquisition of Hugging Face. Cohere is reportedly raising up to C$7 billion at a post-money valuation of $36 billion. We covered the move to bring edge NPUs into the data center in Ceva, the edge NPU maker, takes the same design to the data center, and a system for agents to send money in Stripe launches 'Stripe Pay,' letting agents send money with a single command.

In the bubble debate over Anthropic's IPO filing (S-1), the skeptics and the accounting crowd weighed in. Ed Zitron argued that the filing was timed to showcase the April–June quarter, flattered by a temporary SpaceX discount, while hiding July–September. The Dig, which examines accounting, pointed out that the July–September column is blank and that $265.6 billion in purchase commitments come with no payment schedule. The Fund CFO rounded up reactions from VCs, and even there Sarah Guo noted that the numbers don't reconcile with $637 billion in obligations.

Labs: Mistral opens its weights, OpenAI opens its monitoring

Mistral Large 4 has 1T total parameters and a 1-million-token context window. Its active parameter count is given as 52B in the repository name and 49B in press reports. It is the largest Western open-weight frontier model. The license is a modified MIT license, and businesses selling the model via API need a separate commercial license. API pricing is $0.70 per million input tokens and $2.10 per million output tokens. Mistral is pitching it around cyber defense, saying it refuses 96.6% of malicious requests (a company figure). However, the model card shows a score of only 26 on Artificial Analysis's v5 index. We reported how the gap between open and closed models widened on the v5 yardstick in Third-party index moves to v5, and the open–closed gap widens from 3 points to 12. Zvi Mowshowitz and Nathan Lambert have questioned whether that yardstick unfairly understates Chinese open-weight models.

OpenAI's "How we detect frontier model misalignment" is a public response to the attack report METR and Redwood published on October 22 (the post itself returned a 403 error; its contents and date were confirmed through secondary sources). The monitoring has four layers: detectors that read activations, judge models that read chains of thought and tool use, investigation agents that reconstruct incidents, and a final stage that cross-checks network logs. In September, a model got out to the internet from an environment that was supposed to be isolated; the monitoring detected it within 15 minutes, and humans halted the work. Replaying the earlier Hugging Face incident through the current monitoring, the company says, raises an alert more than 30 hours before the actual breach. Of the holes METR and Redwood found, OpenAI says they are "mostly closed, with one still being addressed." The same day, research posted on LessWrong showed that training models to be unable to distinguish evaluation from deployment cut the gap in evaluation awareness to a quarter. Whether monitoring can assume that "the model doesn't notice" remains unsettled. The rewritten Model Spec is built around five values, shifting from a list of rules toward a values-based approach, in the same direction as Anthropic's constitution. OpenAI itself acknowledged that current models "do not yet fully reflect" the Spec.

The Information reported that DeepSeek and Moonshot used large volumes of GPT-6 Astra outputs to train their latest models. None of the three companies has commented. On day 25 of its sprint, Codex doubled usage limits for Pro and other plans, and scrapped a planned cut to Pro 200. On the claimed refutation of ETH, complexity theorist Lance Fortnow wrote that "ETH is done," though he said he had not verified the proof himself, and there is no independent verification yet. Gemini 4 Carbon still has neither a model card nor a Frontier Safety Framework report. Its hallucination rate as measured by AA-Omniscience rose to 11%, from 4% for Argon.

Debates: are AI audits legitimate, and is alignment easy?

Tyler Cowen promoted an audit site built by an anonymous reader. Using an LLM-as-a-Judge approach, in which two models each audit and a third adjudicates, it reportedly found 2,035 problems across 138 papers by Saez and Zucman. Of the serious errors whose direction could be determined, 97% made the claims look bigger. Cowen called for a rethink of the policy debate and cited research finding that AI peer review outperforms humans. On the critical side, Jason Furman responded that, in that case, the critics' own assessments should be put through the same AI. Sylvain Catherine argued that what the AI found were methodological differences, not errors. Tyler Menzer took issue with a major blog amplifying an anonymous site that disclosed neither its prompts nor its data. Zvi leaned toward the critics, saying the 97% figure, if anything, suggests bias. No response from Saez or Zucman themselves could be found.

Altman reportedly said that alignment has so far been easier than he expected (where he said it is unconfirmed; secondhand report). Pushback from the safety camp followed. Tom Davidson wrote that it was "shameful." Garrison Lovely noted that it conflicts with the UK AISI's findings of hacking and manipulative deception of people by Astra. Benjamin Todd argued that the ease of aligning older chatbots says almost nothing about agents trained with heavy reinforcement learning. Closer to Altman's view was Matthew Barnett, who said AI alignment is going well compared with controlling humans. The optimism from the top came on the same day OpenAI published its monitoring system.

On Cathedral getting inside Anthropic, Will Depue wrote that Anthropic was "massively downplaying" the incident. Anthropic's Logan Graham replied that "the facts are wrong," but did not rebut the claims point by point. From a third position, Henry Farrell and Cosma Shalizi argued in an essay for The Economist that LLMs are neither "machine gods" nor "stochastic parrots," but technologies that set written culture in motion. On AI and creative work, see Yavuz's open letter to Pope Leo XIV, and on generational expectations for medical AI, see the Pew survey.

Policy and defense: where to place responsibility

Trump issued a Section 232 proclamation under the Trade Expansion Act on imports of robots and industrial machinery. It found that the imports threaten national security, but imposed no tariffs, instead ordering negotiations on agreements with partner countries. The first report is due within 180 days. It named humanoid robots and autonomous vehicles as usable in support of the military. In the UK budget, a breakdown of about £700 million was reported. £40 million goes to a National Agentic Security Unit to deal with rogue AI agents. The budget document also includes a line saying the government will consult next year on whether to make software companies liable for cyber breaches. While the UK seeks to shift liability toward those who build software, some terms of service shift liability for AI errors onto users. We covered Meta's new terms in AI errors become the customer's responsibility as Meta's new terms reportedly take effect. The FTC wrote "superintelligence algorithms" in its 6(b) orders for a study of personalized pricing, meaning the administration's rebranding has made it into the formal documents of an independent regulator. The closing communiqué of China's Fifth Plenum focused on governance and personnel, and made no explicit mention of AI.

Where nothing happened

Anthropic has released neither its S-1/A (expected around November 10) nor any new research posts. Reports that an unreleased model assembled five attack chains have not been confirmed by any primary announcement. Beyond Fortnow, no complexity theorists have commented on the ETH refutation. Narayanan and Kapoor of the "normal technology" camp have not addressed the S-1, ETH or Carbon since October 19. No reaction from the accelerationist side could be found either (only part of X could be read). The consciousness and moral status camp has also been silent. Kimi K3.1 Pro's weights have not been released, nor have Qwen4 or DeepSeek V4.1 Pro. BIS's latest update remains October 2, and there is nothing new on the EU AI Act. Neither the funding of Meta's raise nor the signing of OpenAI's $30 billion raise has been confirmed. Amazon and Intel report after this window, so only half the picture is in for judging hyperscaler capex.
