Anthropic’s valuation trajectory reflects accelerating enterprise adoption of its Claude models, with annualized revenue run rate surpassing $65 billion by July 2026 following the $65 billion Series H round closed in May at a $965 billion post-money valuation. This marks a sharp step-up from the $380 billion mark set three months earlier, fueled by hyperscaler commitments and demand for advanced coding and agentic capabilities. Traders in related Polymarket contracts price a roughly 68% chance of reaching $2 trillion by year-end, driven by IPO preparations after the confidential June filing and potential public-market re-rating near or above that level. Key near-term catalysts include any additional funding announcements or regulatory milestones ahead of a possible late-2026 listing, while broader AI capital expenditure trends and competitive positioning versus OpenAI remain central variables.
