Anthropic prepares for a record-breaking $2 trillion IPO

The road to a record listing

Anthropic is preparing to enter the public markets with a filing expected as soon as Monday, October 26. The company is targeting a mid-November listing, with a roadshow scheduled for the week of November 9. If successful, the firm could seek a $100 billion capital injection at a market value of up to $2 trillion.

This potential move would make it the largest IPO on record. The company's valuation has already climbed significantly, reaching $965 billion following a $65 billion Series H round in May 2026. That round included major commitments from cloud giants, including $15 billion from various partners and $5 billion from Amazon.

While the company is scaling rapidly, it faces scrutiny over its financial health. Reports on a confidential draft filing indicate that Anthropic saw $16.3 billion in revenue for the first half of 2026, but also reported an $80.7 billion net loss during that same period. Investors will be watching these figures closely as the company seeks to go public.

A safety-first business model

Anthropic was founded in 2021 by Dario Amodei and his sister Daniela as a "safety-first" alternative to OpenAI. The founders argued that the individuals most concerned about the risks of powerful AI should be the ones responsible for building it. This philosophy has defined the company's identity since its inception.

The company's core business revolves around the Claude models, including Claude Code for software developers and the workplace agent Cowork. Over the last two years, these tools have helped Anthropic become a leading supplier of AI to businesses. Despite this commercial success, Amodei remains a vocal critic of the industry's current pace.

In September 2026, Amodei published an essay calling for a deliberate slowdown in how fast the industry improves AI models. He argued that while progress will still feel fast, the industry must make wise use of the time gained. He has even suggested that the odds of a catastrophic outcome from AI could be between 10 to 25 percent.

The CEO's background and leadership

Dario Amodei's path to leading Anthropic began in the fields of physics and biophysics. He earned a Ph.D. from Princeton in 2011, where he studied the electrical activity of neural circuits. This academic background eventually led him to AI research at Baidu and Google Brain before he joined OpenAI in 2016.

At OpenAI, Amodei rose to vice president of research and helped lead the development of GPT-2, GPT-3, and reinforcement learning from human feedback. He eventually left the company in late 2020 due to disagreements regarding safety and the general direction of the organization. He then co-founded Anthropic with five other former OpenAI colleagues.

Amodei is noted for his willingness to discuss the negative possibilities of AI technology. He has warned that AI could potentially wipe out half of entry-level white-collar jobs within one to five years. He also recently won a preliminary injunction against the Pentagon after refusing to remove certain limits on Claude's use in autonomous weapons.

Infrastructure and future spending

To support its growing user base, Anthropic has secured massive amounts of computing power. The company has lined up gigawatts of capacity from Amazon, Google, and Broadcom. It has also contracted capacity from SpaceX's Colossus data centers to ensure it can continue training its models.

According to reporting by The Wall Street Journal, Anthropic's potential future spending on compute runs to roughly $750 billion. This massive capital requirement highlights the intensity of the current AI arms race. The company must balance these enormous costs against its current revenue and net losses.

The upcoming IPO is intended to provide the capital necessary to sustain this growth. However, the transition to a public company brings new oversight. New York City Comptroller Mark Levine recently urged Amodei to pause the IPO until the company addresses specific safety and governance questions.
