Anthropic surges past openai: a billion-dollar frenzy fuels ai’s next big bet
The market for artificial intelligence is experiencing a seismic shift, and at the epicenter stands Anthropic. Demand for the company’s secondary shares is driving a valuation explosion, leaving OpenAI trailing in its wake, with estimates now exceeding a staggering billion dollars – according to Forge Global’s data.
A private market frenzy
As both Anthropic and OpenAI remain private, investment is largely concentrated in the secondary market. However, a clear trend is emerging: Anthropic is attracting unprecedented interest, while OpenAI’s momentum has noticeably stalled. Initially valued at $852 billion during its March funding round, OpenAI now trades at a significant discount to Anthropic’s current valuation.
Recent trading on Forge Global revealed Anthropic reaching a remarkable $880 billion – a testament to the intense speculative fervor. Even more strikingly, a private investor recently offered $1.15 trillion for a stake in the company, and OpenHome’s Jesse Leimgruber reports a ‘prestigious investment fund’ proposed a $1.05 trillion purchase this week.
The scale of this demand is remarkable; some investors are even exploring unconventional strategies, offering real estate as collateral for Anthropic stock valued at over $800 billion. It’s a feeding frenzy, solidifying Anthropic’s position as the new frontrunner in the ai race.

The rise of claude code
This surge in interest ignited following Anthropic’s $380 billion funding round in just the last three months, led by GIC and Coatue. Its ai coding assistant, Claude code, has captured investor attention, fueling a palpable excitement across Silicon Valley. Experts widely describe this trajectory as an “epic” one – a defining moment for the industry.
Glen Anderson, CEO of Rainmaker Securities, underscores that this ai boom is centered around a ‘generational opportunity’. He recently received an offer for $960 billion – a figure unthinkable just weeks ago, and anticipates a competing bid before the deal can be finalized. “We received an offer, and then, in a day, someone else already bought it,” he stated, highlighting the scarcity of available shares. Even early investors, including Bradley Horowitz of Wisdom Ventures, are reporting ‘daily offers, from the ridiculous to the sublime,’ although they’re strategically declining opportunities that don’t align with their long-term vision.
Meanwhile, Anderson observes a muted demand for OpenAI’s shares this year, significantly below its $852 billion valuation from the last funding round. OpenAI’s momentum has clearly shifted towards Anthropic, leaving it struggling to maintain its position. The market, it seems, is decisively betting on a new champion in the ai arena.
