Anthropic Considers $50 Billion Funding at $900 Billion Valuation: The Full Story of the 'Fastest Revenue Growth in U.S. History' and Implications for Investors
On April 29, 2026, TechCrunch, Bloomberg, and CNBC reported simultaneously that Anthropic, the developer of the Claude AI assistant, has received multiple preliminary offers for a new funding round of approximately $50 billion at a valuation of $85 billion to $90 billion.
Anthropic is reportedly finding it impossible to resist the pressure for this funding round, which could be its final private round before an IPO, and is expected to make a final decision on the round and valuation at its board meeting in May.
Anthropic just completed its previous round in February at a valuation of $380 billion. If this round proceeds under the reported terms, the valuation will not only more than double, but it will also match or exceed that of its biggest rival, OpenAI. OpenAI closed a record-breaking $122 billion round in February at a valuation of $852 billion.
This article breaks down the reality of the revenue growth supporting this 'extraordinary valuation,' the competitiveness of its product suite, and the risks and opportunities investors should watch.
1. Revenue Growth: The Trajectory of the 'Fastest in U.S. History'
1-1. $1B to $30B to $40B: A 15-Month Trajectory
Anthropic's revenue growth is literally unprecedented. ARR (Annualized Revenue Run-rate) has surpassed $3 billion, up from $1.9 billion in early March and $900 million at the end of 2025.
Axios's Jim VandeHei stated, 'I looked for a company that has grown organic revenue this rapidly at this level across every industry and every era, and I couldn't find one. Not in technology, not in oil, not in wartime manufacturing.'
Furthermore, according to TechCrunch sources, the current run-rate has reached nearly $4 billion.
1-2. Overtaking OpenAI
Anthropic officially surpassed OpenAI's $2.5 billion in ARR on April 7, 2026, reaching $3 billion. While Anthropic's revenue grew 30-fold from $100 million to $3 billion in 15 months, OpenAI grew only about 25% from $2 billion to $2.5 billion in the same period.
However, caution is required. OpenAI has prepared an internal memo claiming that Anthropic is overstating its gross revenue accounting by approximately $800 million, disputing the validity of the comparison. This controversy will likely be clarified in the S-1 filing at the time of the IPO.
1-3. Enterprise-Focused Business Model
Approximately 80% of Anthropic's revenue is generated from enterprise and developer workloads. Over 1,000 corporate customers are spending more than $1 million annually on Claude-related services, a figure that has doubled since February.
Anthropic effectively has no consumer phase. While the Claude chatbot exists, it has never been positioned as a competitor to ChatGPT; rather, it has been positioned as a developer tool and a secure enterprise model. Consequently, it has almost no consumer support infrastructure.
2. Growth Engine ①: Claude Code—Dominance in AI Coding
2-1. $1 Billion ARR in 6 Months Since Launch
The biggest driver of Anthropic's rapid growth is the AI coding tool 'Claude Code.' Claude Code was released to the public in May 2025 and reached $1 billion in ARR in six months—faster than ChatGPT or any other enterprise software product in history.
As of early 2026, Claude Code's run-rate revenue has grown to over $2.5 billion, a figure that has doubled since the beginning of 2026. Business subscriptions for Claude Code have increased fourfold since early 2026, and enterprise usage now accounts for more than half of Claude Code revenue.
2-2. The Developer to Manager to Procurement Flywheel
Through an API-first approach, the developer community functions as a de facto voluntary sales force. Developers who like Claude recommend it to their managers, who then approve the procurement. This flywheel operates without a dedicated enterprise sales team for individual deals.
Actual adoption cases are also impressive. Deloitte rolled out Claude Code to approximately 470,000 employees. At Spotify, it was reported at an Anthropic event that "engineers can now initiate large-scale code migrations just by describing them in plain English."
2-3. Ripple Effects on the SaaS Sector
The impact of Claude Code extends beyond Anthropic's own performance. The announcement of Cowork triggered a massive sell-off in global SaaS stocks. The software sector lost approximately $2 trillion in market capitalization due to the realization that agentic AI tools could disrupt traditional enterprise software models.
IBM's stock price recorded a decline of approximately 13.2%, its worst single-day drop since October 2000, the day after Anthropic published a blog post about modernizing COBOL with Claude Code.
3. Growth Engine ②: Claude Cowork—Expansion to Knowledge Workers
3-1. The Arrival of 'Claude Code for General Business'
Anthropic launched Cowork in January 2026. Four engineers built it in 10 days, and the majority of the code was written by Claude Code itself. Cowork provides spreadsheets, file management, report generation, and automated workflows for non-developers.
Anthropic executives have stated, "Engineers believe they can no longer work without Claude Code. We expect all knowledge workers to feel the same way about Cowork."
3-2. Expansion for Enterprises
Anthropic introduced pre-built plugin templates spanning HR, design, engineering, operations, financial analysis, investment banking, equity research, private equity, and wealth management. New MCP connectors for Google Drive, Gmail, DocuSign, FactSet, and others were also shipped.
By embedding itself deeply into specific business domains such as finance, legal, and sales, Anthropic is evolving from a mere AI model provider into a workflow platform.
4. Growth Engine ③: Claude Mythos—A 'Game Changer' in Cybersecurity
4-1. Reasons for Withholding a Public Release
On April 7, 2026, Anthropic announced Claude Mythos Preview. It is a powerful AI model capable of autonomously discovering software vulnerabilities across complex systems. However, Anthropic did not release this model to the general public.
Within just a few weeks of its release, Mythos Preview discovered thousands of zero-day vulnerabilities across all major operating systems, all major web browsers, and other critical software. Among the discovered vulnerabilities was a bug in OpenBSD that had gone undetected for 27 years.
4-2. Project Glasswing and Restricted Access
Through an initiative called 'Project Glasswing,' access for defensive purposes is being provided to major companies including AWS, Apple, Broadcom, Cisco, CrowdStrike, Google, JPMorgan Chase, Microsoft, and NVIDIA.
Of 198 vulnerability reports manually verified by human security experts, 89% matched Claude Mythos's severity assessment, and 98% were within one level of the assessment.
4-3. The Background of the $900B Figure Pointed Out by CNBC
Mythos has become a topic of discussion among several high-level meetings—including members of the Trump administration, tech CEOs, and bank executives—and is part of the reason why Anthropic is seeking new funding. This is because they need to secure the compute necessary to execute Mythos.
For investors, Mythos is a signal of Anthropic's technological superiority, as well as a catalyst that could trigger a repricing of the entire cybersecurity market.
5. Infrastructure Strategy: Multi-Cloud and Compute Security
5-1. Major Partnerships with Amazon, Google, and Broadcom
Entering 2026, Anthropic is rapidly expanding its compute infrastructure.
Amazon has invested up to $25 billion in Anthropic, and Anthropic has secured up to 5 gigawatts of compute capacity for training and deployment. Anthropic has also secured another 5 gigawatts of compute capacity through partnerships with Google and Broadcom, which will come online starting next year. Google also announced plans earlier this month to invest up to $40 billion in Anthropic.
5-2. Differentiation: 'Available on All Three Major Clouds'
Claude is the only frontier AI model available on all three major clouds—AWS (Bedrock), Google Cloud (Vertex AI), and Microsoft Azure (Foundry)—and is trained and run on diverse hardware including AWS Trainium, Google TPUs, and NVIDIA GPUs. This platform diversity means both performance and resilience for enterprise customers.
6. Validity of the $900 Billion Valuation: 5 Points Investors Should Verify
6-1. Revenue Multiples
A $900 billion valuation against $30 billion in ARR equates to an EV/Revenue multiple of approximately 30x. Calculated at the current run rate of $40 billion, it is about 22.5x. While not an outlier for a high-growth tech company, the visualization of profitability is the next step.
6-2. Lack of Profitability Transparency
High compute costs could lead to negative margins in heavy use cases, and scaling while maintaining safety is a critical challenge for Anthropic's focus on Constitutional AI. Even with tens of billions of dollars in annual revenue, the balance of payments remains opaque when considering the massive costs of GPU infrastructure.
6-3. Countdown to IPO
According to multiple reports, Anthropic is considering an IPO as early as October 2026. OpenAI is also reportedly planning a public listing at a $1 trillion valuation in late 2026 or early 2027. This round is highly likely to be the last before the IPO, and it carries significant weight as an anchor for the IPO price.
6-4. OpenAI's Accounting Objections
OpenAI took the unusual step of questioning Anthropic's revenue accounting in an internal memo. This dispute will likely be settled in S-1 disclosures, but investors should be mindful of the differences in revenue definitions (gross vs. net) between the two companies.
6-5. Investor FOMO: Can't Even Get a Meeting Despite a $5 Billion Commitment
Investors are rushing to participate in the round, and institutional investors who have prepared $5 billion commitments have been unable to even secure a meeting with Anthropic CFO Krishna Rao. This 'supply-constrained' investor demand could be a factor that pushes the valuation even higher.
