Rohan Paul says Anthropic's revenue curve will become legendary

On October 28, 2026, Rohan Paul offered the judgment that Anthropic's revenue curve will become legendary. Citing a Bloomberg chart, he said that Anthropic's revenue in the first half of 2026 was nearly 400 times its full-year 2023 revenue, and that no other company in the chart comes close to that multiple; Nvidia, the second-fastest grower, remained below 50 times throughout its first three years after going public, while Alphabet, Meta, Microsoft and SpaceX essentially stayed near the 1x baseline. The same material also states that Anthropic's full-year 2025 revenue was about 100 times that of 2023, so its revenue in just six months of 2026 was about 4 times its full-year 2025 revenue. At present, this judgment appears only in this single source, Rohan Paul, and there have been no subsequent developments.

Aswath Damodaran publishes a valuation article on Anthropic

Aswath Damodaran, a valuation professor at New York University, published a long article valuing Anthropic at $1.475 trillion. In the article, he noted that Anthropic's revenue in the first half of the year was about 14 times that of the same period last year, but growth slowed in the third quarter because OpenAI took market share and Anthropic lacked sufficient computing power. He mentioned that the $80.7 billion book loss in the first half mainly came from $72 billion in non-cash bond expenses, while the actual operating loss was slightly over $8 billion; Anthropic said it had achieved operating profitability last quarter. He believes the biggest risk is over $600 billion in computing power commitments, and that seven co-founders hold 50.1% of voting rights through a single class of shares.

Rohan Paul relays FT: Anthropic IPO hinges on fund managers' fear of missing out

Rohan Paul on October 30, 2026 relayed an analysis from the UK's Financial Times (FT) discussing the bull and bear cases for an Anthropic IPO. The analysis argues that whether fund managers buy into Anthropic depends more on their fear of missing out than on valuation logic. The bearish case presented in the article is that frontier labs, large tech companies and listed neoclouds have disclosed $2.1 trillion in debt and non-cancellable compute commitments, compared with $1.3 trillion in subprime in 2007; take-or-pay contracts could force companies to pay for compute no one uses. There is currently no further evidence-backed development in this matter.

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 Attracts Blackstone to Finance Chip Deal at Over 10% Yield

Anthropic is attracting Blackstone Group to provide financing for its chip deal at a yield of more than 10%. According to an IT Home report, the total debt amounts to $60 billion, of which about $42 billion in senior debt is guaranteed by Broadcom and $18 billion is subordinated debt. A Blackstone fund will invest $9 billion to purchase subordinated debt with a 10% coupon, and the remaining $9 billion is expected to be distributed over the coming months. The report also said that four months ago the yield on a similar Anthropic transaction was 8.5%, indicating that borrowing costs have risen this time.

Anthropic plans to publicly release its prospectus as early as late October and complete its IPO in mid-November

According to Reuters, citing people familiar with the matter, Anthropic plans to publicly release its prospectus as early as late October and complete its IPO in mid-November, with institutional roadshows expected to begin the week of November 9 and a potential valuation of $1.5 trillion. A draft prospectus previously reported by the media shows that Anthropic had revenue of $16.3 billion in the first half of 2026 and a net loss of $80.7 billion, of which about $72 billion came from the revaluation of financing instruments such as convertible notes and was not an actual cash expenditure; compute and infrastructure spending in the first half of the year was nearly $9 billion, accounting for about 55% of revenue, and on an adjusted basis the company had already begun to be profitable in the third quarter. The IPO process is still at the planning stage, and the specific timing and valuation are subject to official disclosure.

Anthropic unveils proactive AI agent Claude Duet

Anthropic unveils its proactive AI agent Claude Duet and opens a research preview. According to the official introduction, the app is built on Claude Opus 5.5 and is now available on iOS, Android, and claude.ai for Pro and Max users in the United States, who must join a waitlist; each morning it delivers a cross-app highlights briefing, can continuously execute tasks in the background, requires user approval before sending messages, making payments, signing documents, or deleting anything, does not allow securities trading or transfers between accounts even with approval, and can call on more than 6,000 connectors and plugins in the Claude Marketplace. A subsequent official clarification added that Claude Duet runs continuously on a cloud computer, can read the inbox, draft replies, book appointments, and carry out routines after the user steps away; passwords, browser cookies, and login tokens do not pass through the model, and the browser runs in a separate virtual machine. On October 22, developer Lydia Hallie said she uses Claude Duet to monitor Slack, email, and her calendar, and believes it makes focused work easier and reduces context switching. On October 24, Nikunj Kothari said Anthropic achieved 10x revenue growth even without launching Duet.
