Anthropic is reportedly accelerating preparations for a potentially record-breaking initial public offering as the Claude developer’s revenue surges and investors increasingly debate whether the company could exceed SpaceX’s historic public-market debut.
Sources indicate Anthropic could make its IPO documentation public as soon as the end of August. Importantly, the company has already completed an earlier step in the process: Anthropic confirmed on June 1 that it had confidentially submitted a draft registration statement for a U.S. IPO. A late-August filing would therefore likely represent the public disclosure phase of that process rather than its first submission to regulators.
The company is also said to be reviewing aspects of its data-retention policies for its most advanced AI systems, an increasingly important issue for enterprise customers using frontier models to process sensitive information.
Anthropic IPO Could Rival or Exceed SpaceX Record
Investor expectations around Anthropic have risen rapidly.
The Financial Times reported that some investors believe Anthropic could reach a valuation of roughly $2 trillion in an IPO, potentially exceeding the record set by SpaceX earlier this year. SpaceX went public at a valuation of approximately $1.75 trillion after raising about $75 billion in its offering.
A valuation at or above $2 trillion would make Anthropic’s listing one of the largest IPOs in history and would represent a dramatic increase from the $965 billion post-money valuation associated with its most recent private funding round.
Secondary-market demand has already pushed implied valuations even higher. Business Insider recently reported that Anthropic shares were changing hands at valuations around $1.5 trillion, with relatively few existing investors willing to sell.
Revenue Growth Is Driving the Valuation Debate
The bullish IPO expectations are being supported primarily by Anthropic’s extraordinary revenue growth.
Anthropic’s annualized revenue run rate exceeded $65 billion by the end of July, according to Reuters, up from approximately $47 billion in May and around $9 billion at the end of 2025.
The company is also reportedly forecasting revenue of between $190 billion and $200 billion in 2028, projections that are playing an important role in discussions over how Wall Street should value the business.
Because Anthropic continues to spend heavily on computing infrastructure, model development and talent, investors are increasingly valuing the company on future revenue and margin potential rather than current profits.
Comparable high-growth technology companies and SpaceX are reportedly being used as reference points when bankers and investors model Anthropic’s eventual public valuation.
Banks Compete for Roles in Anthropic IPO
Wall Street is also positioning itself for what could become one of the most lucrative underwriting mandates in years.
Anthropic is reportedly arranging a revolving credit facility that could exceed $10 billion, with major banks competing to participate. Reuters, citing Bloomberg, reported that leading banks have been asked to commit as much as roughly $1.25 billion each.
Participation in that financing could improve banks’ chances of securing roles in the eventual IPO.
The size of the credit facility provides another indication of how much capital Anthropic may require as it expands infrastructure and serves rapidly growing enterprise demand for Claude.
Anthropic’s Advanced Models Currently Require 30-Day Data Retention
At the same time, data retention is becoming a significant strategic issue for Anthropic.
The company currently requires 30-day retention of prompts and outputs for certain highly capable “Covered Models,” including Claude Fable 5 and Mythos 5. The requirement applies wherever those models are offered and is intended to help Anthropic detect sophisticated attacks, jailbreak attempts and other safety threats that may only become visible across multiple interactions.
Anthropic says the retained information is not used to train new Claude models or for purposes unrelated to safety, and data is generally deleted after the 30-day period.
For other eligible API services, Anthropic continues to offer zero-data-retention arrangements under which customer prompts and responses are not stored at rest after the API response is completed. Covered Models are currently excluded from that option.
Data Retention Could Become an Enterprise Competitive Issue
Reports that Anthropic is considering further adjustments to its advanced-model retention framework come as competition around enterprise privacy intensifies.
OpenAI recently previewed a system called Private Safety Processing designed to provide safety monitoring while preserving zero-data-retention arrangements for qualifying enterprise and API customers. Axios described the approach as a contrast with Anthropic’s current mandatory 30-day retention policy for its most advanced models.
That distinction could become increasingly important for companies in finance, healthcare, legal services and other industries where sensitive business information may be processed by AI systems.
Anthropic has been studying the issue for months. Its Frontier Safety Roadmap states that the company completed an internal review of how data-retention policies could improve AI safeguards and subsequently began a broader project focused on retention practices for future advanced models.
Public Filing Could Give Investors First Detailed Look at Anthropic Economics
A public IPO filing would be particularly significant because investors currently have limited access to Anthropic’s full financial statements.
Although the company confidentially filed its draft S-1 in June, a public prospectus had not appeared in SEC records as of mid-August, according to research reviewing the filing status.
Once disclosed, the prospectus could provide the first comprehensive look at Anthropic’s revenue composition, infrastructure spending, margins, customer concentration, relationships with major cloud partners and potential IPO risks.
Those numbers will ultimately determine whether public-market investors are willing to support the $2 trillion-or-higher valuations currently being discussed.
For now, Anthropic is approaching the market with an unusual combination of explosive revenue growth, enormous infrastructure requirements and rapidly increasing demand for enterprise AI. If the company ultimately matches or surpasses SpaceX’s IPO scale, its listing could become one of the defining tests of investor enthusiasm for the generative AI boom.
