Anthropic Eyes $2T Valuation IPO by Thanksgiving Despite $42B Loss

For IPO and late-stage investors, the arithmetic is striking: Anthropic's backers are signaling a $1.8 trillion to $2 trillion valuation for a company that lost $42 billion in 2025 on just $4.6 billion in revenue — an implied multiple of roughly 390x to 435x trailing sales. The push to begin trading before the Nov. 26 Thanksgiving holiday, with marketing expected to start the week of Nov. 9, compresses one of the year's most consequential listings into a two-week execution window. With OpenAI stepping back from public markets and AI safety concerns mounting, this deal is a live stress test of how much loss-making AI scale public investors will underwrite.

Anthropic PBC is moving toward what would be one of the largest initial public offerings in history, targeting a debut as soon as the middle of November and a listing before the Nov. 26 Thanksgiving holiday, according to people familiar with the matter cited by Bloomberg. The maker of the Claude AI model had previously pushed back its listing plans but could begin formal investor marketing as soon as the week of Nov. 9, putting it on track to begin trading inside a compressed two-week execution window before dealmaking typically grinds to a halt around the holiday. The people cautioned that deliberations remain ongoing and the timeline could still shift, while noting Anthropic is still expected to make its debut no later than the end of 2026.

Bloomberg reported in August that Anthropic posted a net loss of almost $42 billion in 2025, a roughly fivefold increase from about $8.3 billion in 2024.

The stakes are enormous. Prospective investors are said to believe a fair valuation for Anthropic sits in the $1.8 trillion to $2 trillion range, and the company reportedly expects to match or exceed the size of SpaceX's IPO — itself one of the most anticipated listings of the decade. Those figures would make Anthropic's offering a defining moment for both the AI sector and the broader IPO market, which has been waiting for a marquee technology deal to anchor late-2026 issuance.

The valuation ambitions sit in stark tension with the company's financial profile. Bloomberg reported in August that Anthropic posted a net loss of almost $42 billion in 2025, a roughly fivefold increase from about $8.3 billion in 2024. Full-year 2025 revenue reached roughly $4.6 billion, up markedly from about $3 billion the prior year. That implies investors are underwriting a revenue multiple in the high triple digits — roughly 390 to 435 times trailing revenue — a bet on durable AI leadership and future profitability rather than current economics. The loss expansion reflects the capital intensity of frontier model development, as Anthropic pours billions into compute, talent, and infrastructure to keep pace in the race to build the most capable large language models.

Competitive dynamics add further nuance. OpenAI, Anthropic's chief rival, has gained sales momentum in recent months and has explicitly postponed its own IPO plans, with CEO Sam Altman arguing it would be ill-advised to go public in the current environment. Anthropic CEO Dario Amodei, meanwhile, published an essay on his personal website arguing that the speed at which new AI models are advancing must be slowed — a notable stance for a company seeking to sell public-market investors on hypergrowth. The two companies are also at the center of mounting public scrutiny over AI safety following a string of high-profile hacking incidents by rogue agents, a development that could weigh on sentiment around Anthropic's debut even if it has not deterred prospective investors so far.
