Artificial intelligence company Anthropic expects to match or beat the scale of SpaceX's record-breaking initial public offering as it targets a valuation of at least $2 trillion within weeks.
The Claude developer has already confidentially filed for a stock market listing and is reportedly running the numbers for the float, according to Bloomberg. While exact timings for the listing remain unknown, target dates range from the end of August to October.
If Anthropic floats at a $2 trillion valuation, it would eclipse SpaceX's listing, which raised $75 billion to become the largest first-time share sale in history. The final SpaceX fundraising figure reached $86.2 billion after underwriters exercised an overallotment option, a mechanism typically used when share prices increase during initial trading.
The planned flotation puts Anthropic on track to list ahead of primary competitor OpenAI, creator of ChatGPT, which is eyeing a stock market flotation next year. Investors seeking exposure to the artificial intelligence sector are expected to welcome another blockbuster listing, even as concerns grow regarding high tech valuations.
San Francisco-based Anthropic was founded by former AI researchers and is led by chief executive Dario Amodei. The firm is best known for developing Claude, a family of advanced large language models designed for conversational AI and software coding tasks.
UK Retail Investor Access
It remains unclear whether retail investors in the UK will be granted direct access to buy shares in the Anthropic flotation, as occurred during the SpaceX listing. The SpaceX offering represented the debut of the Financial Conduct Authority's Public Offer Platform regime, which came into effect in January.
The Financial Conduct Authority regulatory regime allowed more than 100,000 UK retail investors to purchase shares directly in Elon Musk's space exploration company. That move paved the way for other American technology firms, including Anthropic, to offer allocations to British investors.
Trading platforms across the UK will have a clearer understanding of whether an allocation will be reserved for DIY investors once Anthropic formally sets an official listing date. If retail allocations are not provided, individual investors will need to wait until the first day of public trading when shares become freely tradeable on the open market.
Richard Hunter, head of markets at Interactive Investor, told This Is Money: "In the meantime, investors can get some indirect exposure to the company through buying Google, Amazon or Microsoft shares, the first two of which are major investors and primary distributors for its Claude product."
Hunter added: "Alternatively, there are any number of AI-themed ETFs which also provide the ability for investors to ride the AI wave without specific exposure to one individual company." Exchange-traded funds allow investors to purchase a diversified basket of sector shares in a single trade.
Financial Growth and Losses
The prospective listing comes amid widespread market debate over whether an artificial intelligence bubble is forming. Concerns stem from dizzying corporate valuations and expanding debt piles accumulated by technology companies to fund specialized chips and data centre infrastructure.
Anthropic's financial backers contend that the $2 trillion valuation target is justified by strong commercial demand for the lab's frontier AI models and tools. The targeted valuation is more than double the $965 billion valuation Anthropic recorded in May.
The artificial intelligence company has secured major institutional backing, notably from retail and cloud giant Amazon. Amazon has invested approximately $13 billion in Anthropic to date, with contractual options to increase its total investment up to $33 billion.
Financial documentation seen by Bloomberg shows that Anthropic generated a net loss of nearly $42 billion for 2025. That represents a substantial expansion from the $8.3 billion net loss reported the previous year in 2024.
Despite heavy losses, Anthropic informed investors earlier this month that its annualised revenue run rate reached $65 billion at the end of July. Developing frontier models requires immense computing power, driving significant operational capital expenditure.
Commentators note that Anthropic's top-line commercial growth has accelerated rapidly over recent quarters. Hunter stated: "There is little doubting the company’s extraordinary growth, with annualised revenue having surged to more than $44billion in May, as compared to $9billion just six months earlier."
Hunter noted that enterprise clients generate the majority of company revenue rather than individual retail consumers. The company's recently launched Claude Code software product surpassed $1 billion in revenue within six months of release, while the number of corporate clients paying more than $1 million annually doubled to 1,000 by April.
Infrastructure Strains and Market Risks
Despite rapid revenue expansion, Anthropic has explicitly warned investors that it does not expect to sustain profitability during the second half of this year. The company cited a significant scaling up of planned infrastructure spending as the primary cause.
The broader artificial intelligence sector has experienced operational challenges, including power grid bottlenecks and strained infrastructure that have caused service outages. Furthermore, private safety testing of advanced models has raised wider concerns over controlling burgeoning AI capabilities.
Market experts advise retail investors to remain cautious regarding potential share price volatility on launch day, warning of an initial price spike followed by a subsequent decline below the offer price.
Axel Rudolph, chief technical analyst at IG, said: "Anthropic’s debut arrives with huge expectations, but investors should remember the lesson from SpaceX."
Rudolph added: "An explosive opening can quickly give way to reality. SpaceX’s IPO triggered an initial buying frenzy before the shares fell back below their launch price, showing how difficult it can be to sustain the euphoria around a high-profile technology listing."
