Anthropic, the artificial intelligence lab behind the Claude chatbot, is preparing for what could become the largest initial public offering in history. Half a dozen of the company's backers told the Financial Times that investors expect the five-year-old startup to list at a valuation of $2 trillion or more in October—more than double its current private market valuation and enough to surpass SpaceX as the most valuable company to ever debut on public markets.
The prospect of a $2 trillion Anthropic IPO has electrified Wall Street and Silicon Valley alike. If realized, the listing would unlock billions in gains for early investors, test the public appetite for high-growth, low-profit tech companies, and mark a turning point in the AI boom. It also signals that the race to go public among AI frontier labs is accelerating, with OpenAI—Anthropic's chief rival—reportedly preparing its own blockbuster IPO.
A Historic IPO Wave Takes Shape
Anthropic's move comes amid what Reuters has called the biggest IPO wave in history, potentially delivering $3 trillion in combined value to public markets—despite most of the companies involved reporting no meaningful profits. Bloomberg pegs the current pipeline at an eye-watering $3.6 trillion, encompassing not only AI labs but also SpaceX, the rocket company founded by Elon Musk that has already filed confidentially for its own listing.
SpaceX's IPO, which could value the company at roughly $1.5 trillion, was originally expected to be the largest ever. Anthropic appears poised to steal that crown, but the sheer number of mega-listings has created a logjam. Axios described the situation as "unlike anything we've seen," with investors forced to choose between promising rockets, chatbots, and other speculative assets.
“This is a generational shift in the composition of public markets,” said one venture capitalist quoted by CNBC. “But it's also a test of whether retail investors will buy into valuations that were previously the domain of private unicorns.”
From Pre-IPO Trading to Trillion-Dollar Mark
While the official IPO is planned for the fall, an active secondary market has already begun pricing Anthropic shares. On-chain prediction markets and private trading venues have valued the company anywhere from $1.2 trillion to $1.4 trillion in recent weeks, according to crypto news outlets and market trackers. That represents a dramatic rise from the company's last formal funding round, which valued it at around $900 billion.
The revenue growth driving this optimism is staggering. Anthropic is reportedly generating revenue at an annualized rate exceeding $10 billion, a figure that has doubled every quarter for the past year. Jim Cramer, the CNBC host, said the revenue "backs it up," pointing to enterprise demand for Claude's coding and analytics capabilities. Still, the company spends heavily on computing power and talent, and its net losses remain substantial.
Who Owns a Piece of Anthropic?
Several public companies stand to gain if Anthropic's IPO succeeds. Amazon has invested billions in Anthropic and is its primary cloud provider, with some analysts estimating Amazon's stake could be worth $240 billion at a $2 trillion valuation. Alphabet, through its Google Cloud division and equity positions, also holds a significant minority stake. Both stocks have been cited by financial media as "ways to play" the pre-IPO market without buying direct shares.
For early venture backers like Ashton Kutcher's Sound Ventures, the payoff could be enormous. Kutcher's $30 million early bet on OpenAI could become billions, while Anthropic's first investors—including Dustin Moskovitz and Sam Bankman-Fried (before his downfall)—are similarly positioned for windfalls. Even employees with stock options are watching closely, as a successful IPO would finally provide a liquid exit.
Skepticism Amid the Euphoria
Not everyone is convinced. The AI sector has drawn comparisons to the dot-com bubble, as valuations soar far ahead of fundamentals. A Forbes columnist wrote that despite the hype, they "won't touch" Anthropic at these levels, citing regulatory risks, competitive threats, and the possibility of a market correction. The company itself has yet to file its S-1 prospectus, and regulators may scrutinize its financial projections and governance structure.
“When a company trades at 100 times revenue, you need flawless execution for decades,” said an analyst quoted by Investopedia. “One misstep could erase trillions in market cap.”
Another concern is index inclusion. A $2 trillion Anthropic IPO would likely qualify for the S&P 500, forcing index funds to buy shares and potentially distorting the broader market. Aswath Damodaran, a finance professor at NYU, has written extensively about the challenges these mega-IPOs pose to passive investors, who may be forced to own unprofitable companies at extreme valuations.
The Road Ahead
Anthropic has reportedly begun a "charm offensive" with institutional investors, pitching its long-term vision of safe, aligned AI. The company says its mission—building AI systems that are "helpful, honest, and harmless"—will appeal to public shareholders who value ethical practices. But critics note that Anthropic has increasingly shifted toward commercial products, mirroring OpenAI's trajectory.
If Anthropic goes public at or above $2 trillion, it would dwarf the current largest tech IPOs, including Alibaba's $25 billion debut in 2014 and Snowflake's $3.9 billion offering in 2020. Cerebras Systems, an AI chip maker, recently had the biggest U.S. tech IPO since Snowflake, but its valuation of $4 billion is a rounding error compared with what's coming.
The stakes are not just financial. As NBC News observed, these IPOs will bring AI and space exploration into the retirement accounts of ordinary Americans. That democratization could either validate the AI boom or expose Main Street to its sharpest downturn. The next few months will be pivotal—not just for Anthropic, but for the entire technology ecosystem that has grown up around generative AI.
Key Numbers to Watch
- Potential IPO valuation: $2 trillion (October 2026)
- Pre-IPO secondary market range: $1.2 trillion – $1.4 trillion
- Projected combined value of AI/space IPO wave: $3.6 trillion – $4 trillion
- Anthropic's reported annualized revenue: $10 billion+
- SpaceX IPO valuation: ~$1.5 trillion
- OpenAI expected valuation: $1.5 trillion+
As the countdown to October begins, the world will be watching whether Anthropic can turn a staggering private valuation into a public market triumph—or whether the era of trillion-dollar unprofitable IPOs crashes back to Earth.
