Financial Snapshot

- 2025 net loss: $42 billion, of which $34 billion was a non-cash charge.

Investor Stakes and Potential Returns
- Iconiq Capital’s stake could double if the IPO achieves a $2 trillion valuation.
- Spark Capital’s original $75 million investment now translates to a $7 billion holding.
- Sound Ventures’ cumulative investment is valued at several billions of dollars.
- GIC and Sequoia each hold about 1 %, representing multi-billion-dollar positions.
- Menlo Ventures and Lightspeed each own <2 % stakes.
Official Market Context
- Sources say the IPO will test whether Anthropic can secure a $1.5 trillion valuation amid a broader slowdown in AI-related listings.
- Other AI infrastructure firms—CoreWeave, Nscale, Switch—have delayed offerings because higher interest rates have squeezed financing conditions.
- West Riggs, head of equity capital markets at Truist Financial Corp., described the overall market as “paralyzed” while investors await Anthropic’s debut.
Criticism and Safety Concerns
- NYC Comptroller Mark Levine wrote to CEO Dario Amodei urging a pause until the company can address AI-risk issues highlighted in its prospectus.
- Former Anthropic researcher Jacob Coxon warned that “Neither company is acting responsibly” and cautioned “Do not underestimate the power of this technology.”
Conflicting Reports and Gaps
- Valuation expectations differ: some sources cite a $1.5 trillion target, others a $2 trillion goal.
- Revenue figures for the first half of 2026 vary: one report lists $16.3 billion, another cites $16.8 billion for Q3 alone.
- Loss numbers also diverge: a $42 billion net loss for 2025 is reported alongside an $80.7 billion loss for the first half of 2026, the latter largely reflecting a large accounting charge.
What’s Next
- Public filing of the S-1 prospectus is expected on October 23.
- The roadshow is slated for the week of November 9.
- Assuming market conditions remain favorable, Anthropic could list on a U.S. exchange in mid-November, subject to SEC review and final pricing decisions.
