Anthropic reportedly planned an investor day for Oct. 14, 2026, and could begin formal marketing for a possible IPO during the week of Nov. 9. The reported target was a Nasdaq debut before Thanksgiving, which falls on Nov. 26 this year. These prospective dates put a possible U.S. offering on the calendar, while its financial figures show rapid revenue growth alongside large losses and infrastructure obligations.
NeoTeo previously covered the possible November window in its earlier report on Anthropic’s IPO timing. The more specific schedule includes the reported investor-day plan and a possible start to marketing.
Anthropic’s reported IPO timetable
The investor day was reportedly scheduled for Oct. 14, ahead of the possible marketing period in the week of Nov. 9. A debut before Nov. 26 was described as a target. The dates are plans and projections, not completed milestones.
The valuation and offering size are estimates
The potential IPO valuation was reported at $1.8 trillion to $2 trillion, with expected proceeds of $100 billion. The valuation estimate refers to the company as a whole; the proceeds figure describes the anticipated size of the offering. Neither supplies a per-share price.
Anthropic’s reported 2025 revenue and losses
Reported figures put Anthropic’s 2025 revenue at about $4.59 billion, its operating loss at $8.06 billion, and its net loss at roughly $42 billion. Revenue measures sales; operating loss and net loss are distinct measures of losses. The reported financial figures break down this way:
| Measure | Period | Amount |
| Revenue | 2025 | About $4.59 billion |
| Operating loss | 2025 | $8.06 billion |
| Net loss | 2025 | About $42 billion |
About $34 billion of the net loss was attributed to an accounting adjustment tied to the estimated value of financial instruments convertible into shares. Anthropic’s future cloud, computing and infrastructure obligations were reported at roughly $518 billion.
Two different measures of revenue concentration
Two unnamed customers reportedly accounted for 24% of Anthropic’s 2025 revenue. Separately, Amazon and Google cloud marketplaces were linked to nearly 47%, or about $2.16 billion, of revenue that year. The first figure measures customer concentration; the second measures revenue through marketplace channels.
