🧭 Anthropic Raises $10 Billion at $350 Billion Valuation — Term Sheet Signed

Anthropic has signed a term sheet for a $10 billion funding round at a $350 billion valuation, according to reporting by CNBC, Bloomberg, and TechCrunch. The round is led by Coatue Management and Singapore's sovereign wealth fund GIC. The valuation — which nearly doubles Anthropic's prior $183 billion Series F valuation from just three months earlier in October 2025 — reflects the dramatic acceleration in enterprise adoption of Claude across the fourth quarter of 2025 and the company's strengthening competitive position.

Key context

• Valuation trajectory — Anthropic's valuation has approximately doubled every three to four months since the Series E in early 2025, tracking the rapid expansion of enterprise AI deployment
• Round composition — Coatue and GIC lead; additional participation from existing backers including Lightspeed, Fidelity, and Iconiq is reported alongside new institutional investors
• Use of proceeds — Anthropic has indicated proceeds will fund continued investment in model research, safety evaluation infrastructure, and the operational scaling required to serve the growing Enterprise customer base
• Note on finalisation — the term sheet was signed today; the round is expected to close formally in the coming weeks as legal documentation is completed

The funding round comes at a moment when Anthropic is executing across multiple dimensions simultaneously: the Claude 4.x model generation, the expansion of Claude to third-party cloud platforms, the launch of Claude Code, and a significant push into enterprise contracts.

🧭 Claude Models Now Enabled by Default in Microsoft 365 Copilot

Claude models are now enabled by default across Microsoft 365 Copilot for most commercial tenants worldwide. Prior to today, the integration announced in September 2025 required tenant administrators to explicitly opt in. The change means that the millions of Microsoft 365 commercial customers with Copilot licences now have access to Claude capabilities within the Copilot experience without requiring any administrator action.

Under the updated integration, Claude operates subject to Microsoft's own Product Terms and Data Processing Agreement (DPA) rather than requiring a separate direct agreement with Anthropic — a significant simplification for enterprise compliance teams. The arrangement means that enterprises already running Microsoft 365 under their existing Microsoft enterprise agreements have the data handling and compliance commitments they need without additional contracting.

Availability and exclusions

• Available — most Microsoft 365 commercial tenants globally; Claude is enabled by default from today
• Not available at launch — EU/EFTA/UK tenants (compliance review in progress), US and other government cloud deployments (GCC, GCC High, DoD) where separate regulatory clearances apply
• Administrator controls — tenant administrators retain the ability to disable Claude within Microsoft 365 Copilot settings if their organisation policy requires it
