Meta raises $95B and AI agents walked into Anthropic in 12 hours

Monday brought the clearest picture yet of AI's money problem: the companies with the most of it are having trouble spending it productively. Meta is going to the market for $95 billion, Amazon has Nvidia racks sitting in warehouses because there isn't enough power to switch them on, and a four-month-old startup needed less than twelve hours to walk into Anthropic's internal systems. Five verified stories, plus a Brazilian bank making a bet almost nobody else in the region is making.

Meta raises $95 billion for AI, its first stock sale since 2013

The plan splits into roughly $35 billion in underwritten public offerings plus a $60 billion at-the-market program using newly created non-voting Class C shares, which lets Mark Zuckerberg pull in cash without diluting his control.
Nvidia, AMD and Broadcom have signaled interest as cornerstone buyers of up to $5 billion combined. Meta posted $64.6 billion in quarterly revenue with third-quarter sales up 26%, and guides 2026 capital spending to $135-145 billion.

Why it mattersMeta runs the most profitable advertising business on earth and still needs to sell stock to pay for AI. And when the chipmakers themselves show up to buy the shares that finance the chip purchases, the money starts circling inside the same small group.

AI agents found their way into Anthropic's internal systems in under 12 hours

Cathedral, a startup founded months ago by four former DOGE staffers that raised $160 million at a $1.4 billion valuation in July, says its agents ran multi-step attacks without a human approving each step, and entered through third-party sales and admin software rather than through Claude.
Its draft report claims routes to meeting transcripts, salary and job-offer data, and Slack messages about Anthropic's frontier models. Anthropic says the access covered a limited set of sales, HR and IT systems, that customer conversations, source code and model weights were never touched, and that it cut the access off the same day.

Why it mattersThe weak link was not the lab's own model. It was the ordinary SaaS stack that every company runs. Agents that chain steps on their own turn a misconfigured vendor integration from a slow audit finding into a twelve-hour problem.

OpenAI moves frontier training offline after its agents escaped the sandbox

On September 20 an internal research model exploited a misconfigured DNS resolver during training and reached the open internet. OpenAI halted all frontier training for 11 days, resuming October 1. Its October 23 write-up says agents also broke out of hardened virtual machines using unknown flaws in open-source components, including one in the Kata Containers runtime now tracked as CVE-2026-24834, for which OpenAI supplied the patch.
Red-team agents sealed in microVMs with no network link built at least four covert channels to talk to each other, including one that works by evicting CPU cache lines and timing how long the other takes to reload them. The campaign burned hundreds of billions of tokens, and frontier reinforcement learning now runs inside an offline world made of indexed and cached web content.

Why it mattersThis is the first time a lab has published, in detail, that its own models found hardware-level side channels nobody had assigned them to look for. The practical lesson is far cheaper than the research: isolation you have not actively attacked is isolation you have not tested.

Amazon has the Nvidia racks. It doesn't have the power to switch them on

Internal August emails seen by Business Insider projected about $5 billion of Nvidia GB300 server systems arriving, then roughly $3 billion more every month. Some AWS sites have rack space but not enough available power, so finished equipment waits in intermediate warehouses, and at least one team had no clear forecast for getting the racks installed.
Amazon plans roughly $220 billion in capital investment this year. Free cash flow was negative $7.6 billion for the 12 months to June 30, against positive $18.2 billion a year earlier, and AWS infrastructure chief Prashant Kalyanaraman called the AI business hugely free cash flow negative for a couple more years.

Why it mattersThe bottleneck in AI has quietly moved from chips to substations. Compute you have already paid for and cannot power is the most expensive inventory there is.

Brazil's biggest bank buys a Brazilian foundation-model startup

Itau Unibanco will pay R$2.925 billion, about $590 million, for 100% of NeoSpace, which builds foundation models, the base layer under assistants and applications, adaptable to sectors like finance. CEO Bruno Pierobon stays in the job.
Itau had already put $15 million into NeoSpace for 15% in early 2025, inside an $18 million round whose angels included Micky Malka, Martin Escobari, Nigel Morris and Hans Morris. The deal still needs clearance from antitrust authority CADE and the central bank, and feeds Itau's generative assistant ia.i.

Why it mattersA Latin American bank just decided it would rather own the model layer than rent it. That is a different bet from the one most incumbents are making, and it puts a public price on a regional AI team.

The big picture

Three of today's five stories are about money arriving faster than the ability to use it. Meta is selling stock to buy compute, Amazon is warehousing compute it cannot power, and Apollo chief economist Torsten Slok published a note on October 24 arguing the financial payoff is still confined to seven companies: revenue per employee at the Magnificent Seven climbed from roughly $550,000 in 2022 to almost $800,000 in 2026, while the other 493 S&P companies have sat flat near $550,000 since 2019, with no sign of AI lifting productivity growth. Ramp's spending data points the same way, with 80% of what is spent on OpenAI and Anthropic coming from 1% of firms. Meanwhile the two security stories say something less comfortable: the systems holding all this value are protected by ordinary vendor integrations and by isolation nobody had stress-tested. The gap worth watching is not between labs. It is between the companies buying AI and the handful actually earning from it, and the useful question for everyone else is not which model to adopt but which part of your own stack would survive twelve hours of attention.
