Anthropic Valuation Poised to Overtake OpenAI's as Prediction Markets Signal Major Shift

Prediction markets are pricing a greater than 90% probability that Anthropic's valuation will surpass OpenAI's by the end of 2026.

This sentiment is driven by Anthropic's recent massive funding rounds, a landmark long-term compute deal with Amazon, and rapidly accelerating enterprise revenue.

While OpenAI's last confirmed $500 billion valuation remains the benchmark, Anthropic's momentum suggests it is on a clear path to exceed it.

Prediction markets are now signaling a very high probability that Anthropic's valuation will surpass OpenAI's by the end of 2026.

So, what's behind this dramatic shift in sentiment? It boils down to three key pillars: massive capital inflows, secured computing power, and strong enterprise sales.

First, let's talk about capital. Anthropic recently raised a staggering $30 billion at a $380 billion valuation in February 2026. Now, reports suggest they are already in talks for a new round at a valuation around $900 billion. This puts OpenAI's last confirmed valuation of $500 billion from late 2025 squarely in its sights. Even secondary markets, while less reliable, are trading Anthropic shares at levels implying a valuation near $1 trillion.

Second is the critical resource of computing power. In April, Amazon committed up to $25 billion in investment and Anthropic pledged over $100 billion in spending on AWS cloud services. This secures access to Amazon's powerful Trainium AI chips. For an AI company, guaranteed access to large-scale computing is like an oil company securing a massive oil field; it de-risks their future growth and makes investors more confident.

Third, Anthropic is proving it can make money, fast. The company's annualized run-rate revenue has soared past $30 billion, driven by strong adoption from enterprise clients, particularly for high-value services like its coding assistant, Claude Code. This focus on business customers provides a clearer and more predictable path to monetization.

These recent developments didn't happen in a vacuum. They build on a series of rapid valuation step-ups, like Anthropic's jump from $183 billion to $380 billion in just five months. When traders on prediction markets see this powerful combination of fresh capital, secured compute, and accelerating revenue, they are betting that Anthropic has the momentum to officially overtake its main rival in the AI race.
