Anthropic Plans September or October IPO at $965 Billion Valuation Amid Trust and Competition Pressures

Anthropic is preparing for an IPO in September or early October 2026 with a $965 billion valuation, aiming to set a global record for the largest public listing while assuring investors of sustained rapid growth and measures to counter societal resistance to AI.

Anthropic is intensively engaging potential investors as it prepares for an IPO in September or early October 2026. The company, valued at $965 billion, plans to set a global record for the largest IPO through this listing, while assuring investors that it will maintain rapid growth and take measures to address societal resistance to AI.

Factual Overview

According to multiple reports, Anthropic confidentially submitted IPO documents to the U.S. Securities and Exchange Commission before June 1, 2026. In early May, the company's annualized revenue run rate based on that month's sales exceeded $47 billion. Its current valuation has reached $965 billion. Sources familiar with the matter revealed that the listing timeline is locked in for September or early October, while its main competitor OpenAI will not complete its IPO until at least 2027. SpaceX went public on June 12, with its market capitalization briefly surpassing $2 trillion after listing; as of the close on August 10, its share price stood at $138.74, with a market cap of $1.83 trillion.

Mechanism Analysis

The core logic of this roadshow is to hedge against external pressures with growth prospects and application expansion. Company executives downplayed the threat of low-cost Chinese AI models in meetings, emphasizing their focus on frontier models with leading capabilities. At the same time, they revealed to some investors plans to aggressively expand AI applications in healthcare and biology to alleviate negative public perception. The explosive popularity of the ClaudeCode tool has directly driven demand, and the company has signed multiple large-scale computing procurement agreements with SpaceX, Google, and others, including up to 5 gigawatts of new capacity and 5 gigawatts of next-generation TPU capacity. Strong demand has also led to multiple intermittent service outages on the platform.

Investor concerns center on three categories of business sustainability: the impact of low-cost Chinese models, tense relations with the Trump administration, and opposition to data center construction across the United States. These inquiries reflect the market's scrutiny of AI companies' financial stability. Anthropic has not yet disclosed precise offering pricing or a final timeline.

Industry Impact

In terms of the competitive landscape, Anthropic's IPO pricing and post-listing performance will serve as a benchmark for valuations of leading AI companies. OpenAI's delayed IPO means Anthropic has the opportunity to face public market scrutiny first. Upstream and downstream computing suppliers will directly benefit from continued procurement, but service stability pressures will also transmit to the infrastructure layer. Enterprise users and developers can expect more vertical applications in healthcare and biology to materialize, but they will need to bear the risk of potential service interruptions.

Some Silicon Valley executives have grown uneasy about Anthropic's increasing influence in the AI ecosystem, which could affect the depth of future cooperation. The underlying logic of trillions of dollars in global AI capital expenditure rests on expectations of sustained explosive demand growth; should the public market deliver a different valuation signal, the pace of capital expenditure could be adjusted.

Comparisons and Precedents

SpaceX's sharp pullback after an initial surge on its listing day provides a direct reference for Anthropic. Some optimistic analysts predict Anthropic's valuation could surpass SpaceX's listing peak, but SpaceX's current market cap has already retreated to $1.83 trillion, demonstrating that volatility risk from private to public markets is real. Anthropic's $47 billion annualized revenue run rate disclosed in May coexists with the reality that it remains loss-making, forming a comparability with SpaceX's financial characteristics around its listing.

Strategic Assessment

Based on available information, the most likely development path is for Anthropic to complete its listing in the fall of 2026, with the IPO pricing directly reflecting the market's comprehensive assessment of AI commercialization paths and regulatory pressures. Confirming signals include the final offering price range disclosed in listing documents, first-week trading volume and stock price volatility after listing, and whether healthcare and biology applications show revenue contributions in financial reports.

If low-cost Chinese models continue to catch up in capability, or if resistance to data center construction escalates further, the public market may demand clearer proof of cost control and revenue diversification from Anthropic. Conversely, if demand for tools such as ClaudeCode remains strong and service stability improves, the valuation is likely to find support. Investors should closely track the actual implementation of the company's computing procurement and progress in vertical applications.
