Anthropic has given investors just 48 hours to submit allocations for its latest fundraise, expected to be roughly $50 billion and close within two weeks. The AI company Anthropic is targeting a potential $900B+ valuation that could surpass OpenAI's $852 billion mark, driven by soaring revenue and demand for its Mythos AI model.

Anthropic Accelerates Fundraising Timeline

Anthropic is moving rapidly to close what may be its final private fundraise before a potential IPO later this year. The AI company Anthropic has asked investors to submit allocations within the next 48 hours, with the round expected to close within two weeks, according to sources familiar with the matter . TechCrunch reports the fundraising round is expected to be roughly $50 billion, positioning the company to secure massive capital for its expanding computing needs.

The potential $900B+ valuation would represent a remarkable acceleration for a company valued at just $61.5 billion in March 2025

2

. This trajectory shows the valuation jumping to $183 billion by September 2025, then $380 billion in February 2026, and now targeting over $900 billion—a staggering increase in just 14 months. Given the intense investor interest, sources indicate the final valuation may well exceed the $900 billion target.

Revenue Growth Fuels Investor Demand

The extraordinary investor interest stems largely from Anthropic's explosive revenue run rate. While the company publicly announced its annual revenue run rate has surpassed $30 billion this month, sources with knowledge of the company's financials indicate the run rate is currently closer to $40 billion

1

. This represents unprecedented growth, with revenue jumping from approximately $9 billion by the end of 2025 to around $30 billion by March 2026

2

.

Around 80% of revenue comes from business customers, with more than 1,000 companies paying over $1 million annually for its services

2

. This enterprise focus has proven lucrative and demonstrates the company's ability to monetize its AI model technology at scale, a challenge that has plagued many AI startups.

Mythos AI Model Drives Computing Power Needs

A major catalyst behind the fundraising round is Anthropic's new Mythos AI model, launched on April 7 as a cybersecurity-focused AI system

2

. Mythos has attracted significant attention from US government officials, major tech leaders, and bank executives, creating urgent demand for expanded capacity. However, the White House has expressed concerns about expanding Mythos access due to insufficient computing power, fearing it could affect government access if more users are added.

Despite securing substantial support from Amazon, which plans to invest up to $25 billion and provide compute capacity, and Google, which has committed up to $40 billion plus additional computing power, the company still needs more resources to scale Mythos effectively

2

. The new funding will enable Anthropic to directly purchase additional computing resources to meet this demand.

Race to Surpass OpenAI Intensifies

At $900 billion, Anthropic would not only more than double its February valuation of $380 billion but would also surpass OpenAI, which closed a record-breaking $122 billion round at an $852 billion post-money valuation earlier this year

1

. This would mark a significant shift in market competition within the AI sector, potentially dethroning OpenAI as the most valuable private AI company.

Interestingly, Anthropic's shares were already trading near $1 trillion value in secondary markets due to strong demand and limited share availability

2

. The $900 billion private fundraise would actually price the company slightly lower than its secondary market value—an unusual dynamic since private funding rounds typically command higher valuations.

Early Backers Eye Potential IPO Exit

Despite the intense demand for this round, some early backers—particularly those who invested in 2024 or earlier—are skipping participation

1

. These investors are instead waiting to potentially cash out during Anthropic's anticipated potential IPO later this year, viewing a public listing as a more lucrative exit opportunity.

Bloomberg reports the potential IPO could happen as early as October 2026, with Anthropic in talks with major banks including Goldman Sachs, JPMorgan Chase, and Morgan Stanley

2

. The IPO could raise around $60 billion, making it one of the largest public offerings ever. This timing would put additional pressure on OpenAI, which is also expected to go public in 2026, setting up a direct competition for investor capital and market dominance.
