Investors Question Anthropic’s $4 Trillion IPO Upside as OpenAI and Cheaper Models Pressure Growth
3 articles · Updated · Financial Times · Sep 19
Summary
$65 billion in annualised revenue by July has not settled Anthropic’s IPO debate, with investors estimating its post-listing value anywhere from $1.5 trillion to $4 trillion.
OpenAI’s July release of GPT-5.6 helped it overtake Anthropic in weekly customer spend for the first time in more than 2.5 years, sharpening doubts that Anthropic can keep its current growth pace.
Cheaper open models from Chinese groups and Meta are also closing the performance gap, pushing customers to switch providers more easily; Ramp said router-driven competition cut its AI spending by 40%.
Anthropic still shows stronger stickiness than OpenAI—22.5% of users remain after 12 months versus 13.2%—but investors are also probing revenue concentration, regulatory risk and whether AI economics will commoditise.
Safety concerns add a wider overhang: chief executive Dario Amodei has urged labs to slow cutting-edge development, a stance that could trim training costs but also give rivals, especially in China, more time to catch up.
With smart routers slashing enterprise AI costs, will Anthropic's multi-trillion-dollar IPO survive the rapid commoditization of frontier models?
Despite industry-leading customer retention, can Anthropic maintain premium pricing as cheaper open-source models rapidly close the performance gap?
Anthropic’s Historic $2 Trillion IPO: Racing OpenAI, Navigating Regulation, and the Battle for AI Supremacy
Overview
Anthropic is racing toward a landmark IPO in October 2026, taking advantage of OpenAI’s decision to delay its own public listing. After raising its valuation to $965 billion through massive funding rounds, Anthropic is set to become Wall Street’s top AI investment opportunity. However, its rapid growth faces challenges: its token-based revenue model has caused budget crises for enterprise clients, leading many to seek cheaper alternatives. Regulatory hurdles also emerged when U.S. authorities forced Anthropic to suspend access to its most advanced models, allowing Chinese competitors to gain market share. Despite these pressures, Anthropic strengthened its safety governance by appointing Ben Bernanke to its oversight trust, appealing to investors focused on responsible AI.
