AI giant Anthropic files for IPO, mega Wall Street debut next month - key details

Anthropic, the AI company behind the Claude chatbot, disclosed an $80.7 billion loss for the first half of 2026 as it prepares to go public. The prospectus filed with the US Securities and Exchange Commission reveals that revenue jumped to $16.3 billion in the period, up from $1.1 billion a year earlier. However, the company incurred a significant net loss, mainly due to non-cash adjustments related to convertible debt and other financing instruments.

This loss includes $72 billion in the accounting adjustments and $42 billion in 2025 alone. The company's spending on AI infrastructure reached $9 billion in the first half of 2026, up from $7.3 billion in the previous year, reflecting the escalating costs of developing advanced AI models. Anthropic aims for a market debut on Nasdaq under the ticker ANT, potentially valued between $1.5 trillion and $2 trillion, with Goldman Sachs and Morgan Stanley leading the offering.

The listing is expected as early as November, but the company has not yet confirmed the date or offer price. Despite the substantial loss, analysts believe a $2 trillion valuation is not unreasonable given Anthropic's rapid revenue growth, viewing it as an infrastructure layer for how businesses will operate.
