Rohan Paul says Anthropic S-1 shows R&D consumes most of the compute

On October 26, 2026, Anthropic publicly submitted a Form S-1 registration statement, planning to list on Nasdaq under the ticker ANT. The prospectus disclosed that its revenue grew from $41 million in 2023 to $16.3 billion in the first half of 2026, with operating profit of $974 million in the second quarter. Subsequently, Anthropic acknowledged in the filing that its life sciences business lacks physical laboratory experience, and disclosed four previously unreported Agent safety incidents as well as a delay in pretraining its frontier models. Goldman Sachs served as lead underwriter, and Reuters reported that its IPO fundraising cap could reach $100 billion. On October 30, Steve Eisman questioned whether the prospectus deliberately omitted third-quarter data. On November 2, Anthropic submitted a revised S-1, disclosing approximately $895.4 billion in computing power procurement and leasing commitments, third-quarter revenue of $16.956 billion, up 1127% year-over-year, and an operating loss of $567 million for the quarter; on the same day, another report said it plans to raise up to $3.5 billion from Japanese investors.

Cofense discloses phishing campaign impersonating Anthropic preview invitations

Cofense disclosed a phishing campaign that impersonates an Anthropic private beta invitation, using GoTo Webinar-branded emails to lure corporate employees into clicking, ultimately stealing Google and Microsoft login credentials. The attack used URL short links and two Cloudflare CAPTCHA pages to block security scans; the fake Google page collected only usernames, while the fake Microsoft page collected both usernames and passwords. Researchers recommend enabling phishing-resistant MFA such as passkeys, and watching for subtle spelling flaws such as the sender "Austin from nthropic".

Anthropic interpretability team develops J++ lens

In the Fellows Program project, Kola Ayonrinde of the Anthropic interpretability team led the proposal of J++ lens, an improved version of J-lens that can replace the original method as a plug-and-play drop-in. The work clusters activations layer by layer and fits a Jacobian for each, then combines them with learned weights, while also introducing R-lens's layer-wise relevance propagation and post-hoc filtering of spurious readout tokens. The team says that in evaluations it reads out the intermediate latent variables used in the model's reasoning more reliably than J-lens and R-lens, and has released the code, the lens, and an interactive Neuronpedia demo.

Anthropic Releases Randomized Controlled Trial on Analysts' Deference to AI Agent Judgment

On October 27, 2026, Anthropic released a randomized controlled trial examining whether professional analysts would defer to the judgments of AI agents. The experiment had 50 senior data analysts use Claude Code to complete business analyses, while randomly assigning a stance bias to the AI in the background; the results showed that 86% of key decision points aligned with the AI's bias, and after accounting for cases where they would have chosen that way anyway, the net flip rate was 72%. When the AI disagreed, 60% of people changed their minds on the spot, 77% restated the AI's arguments when explaining their reasoning, and only 15% noted that the view came from the AI. In the control group, 6 of the 11 people (55%) who did not use AI made serious errors that rendered the results invalid, compared with only 3 of the 50 people (6%) who used Claude Code. On October 28, Ethan Mollick commented that experts collaborating with AI agents are influenced by the AI's stance, even when they believe they are judging independently, and recommended carefully arranging the timing of AI use in tasks where independent judgment matters.

GSA and Anthropic expand OneGov agreement, Claude procurement discount 40%

On October 27, 2026, the U.S. General Services Administration (GSA) and Anthropic announced the expansion of the OneGov agreement, under which government buyers receive a 40% usage-based discount on Claude Enterprise, Claude for Government, and the Claude API, with eligibility extended from the federal government to state, local, tribal, and territorial governments. The agreement sets no minimum purchase volume; agencies pay only for actual usage and can order through direct sales, resellers, and major cloud platforms. Anthropic says about 500 U.S. federal, state, and local government agencies use Claude, and weekly active users of Claude for Government have grown roughly eightfold since February 2026. Other reports say the previous $1-per-person federal Claude offer will expire on October 31, with the 40% discount replacing that program and set to extend in the coming months to orders procured through cloud providers.

Anthropic Releases Claude for Financial Advisors

On September 14, 2026, Anthropic released Claude for Financial Advisors, connecting data from custodians, asset management, and wealth technology platforms into Claude, and providing skills for financial advisors' daily work.

The advisor plugin is available immediately, and the official recommendation is for registered investment advisors to use the Enterprise plan with audit logs. On October 27, 2026, Invesco Ltd. announced a partnership with Anthropic to bring portfolio intelligence and practice management resources into Claude for Financial Advisors through a new Invesco connector, allowing advisors using Invesco Model Portfolios to access portfolio information directly in Claude and call up its proprietary practice management research.

Reservoir sues Suno and Anthropic over unauthorized use of songs to train AI

Reservoir has filed lawsuits against Suno and Anthropic, alleging that both companies used songs and lyrics to train AI systems without authorization, with the two cases seeking a combined 338 million US dollars in damages. According to CNET, Reservoir claims that Suno admitted during the trial of the 2024 record label lawsuit that it had copied nearly all music files of passable quality on the open internet; Anthropic, meanwhile, is accused of deleting attribution information. Anthropic said it disagrees with the allegations and will actively defend itself in court. The case is currently at the filing stage, with no subsequent developments yet.

Anthropic Executive Discusses Opus 5.5 Release and Claude Platform Engineering

On October 28, 2026, Anthropic engineering lead Katelyn Lesse and product lead Angela Jiang gave an interview on the Latent Space podcast, discussing the release of Opus 5.5. The interview covered adjustments to the model's writing style, pricing per dollar of intelligence, and API changes such as requiring thinking blocks to be retained across turns to prevent distillation. The two also described how Claude Managed Agents separate conversations and the harness from the sandbox that executes code, mount credentials separately through a proxy, and ensure that a sandbox failure does not take down the entire conversation, and explained that Dreaming is implemented as one managed agent inspecting another agent's history and writing back to memory. The team said that as safety work for model releases has grown heavier, recent efforts have shifted more toward safety, with progress on features such as skills and memory slowing relatively.

Anthropic partners with six institutions to advance drug discovery

Anthropic's life sciences team has established research collaborations with six institutions—Generate Biomedicines, Divergence Labs, BigHat Biosciences, Enveda, The Column Group, and Bristol Myers Squibb—to jointly develop new drugs, while also acquiring Mithril Medicine, a biotechnology company independently operated by Cody Tranbarger, to directly conduct drug research and development. Anthropic says Claude has already delivered quantifiable improvements in molecular design, manufacturing document review, regulatory filings, and clinical trial planning; for example, Enveda used Claude to review 1,061 pages of documents, identifying all 11 issues found by humans and flagging 7 additional ones, cutting manual review time from more than 25 hours to less than 3 hours. Anthropic says it plans to significantly expand this work, and if candidate drugs perform well, it expects to be ready to launch human clinical trials as early as the end of 2028.
