The Qatar Investment Authority has invested in US artificial intelligence company Anthropic as part of a $13bn Series F funding round that valued the firm at $183bn, Doha News reported on September 3.

ICONIQ Capital led the round with co-leadership from Fidelity Management & Research Company and Lightspeed Venture Partners, whilst Blackstone, Coatue, BlackRock and other global investors participated. QIA's stake in the round was not disclosed.

This latest investment round investment adds fuel to the arms race in AI companies with Gulf monarchies backing different companies and in some cases including Saudi Arabia hosting them in their countries. The company has grown in popularity with its Claude AI model launched in March 2023. The company added it has an annualised revenue surging from $1bn at the start of 2025 to over $5bn by August.

Enterprise adoption and strong uptake of Claude Code, which has exceeded $500mn in run-rate revenue and grown 10-fold in usage over three months, drove the revenue increase.

Anthropic now serves more than 300,000 business customers, with large accounts generating over $100,000 annually rising seven-fold in the past year.

The sovereign wealth fund's previous investments in AI-focused ventures including Databricks and Applied Intuition.

Chief Financial Officer Krishna Rao said investors' backing demonstrates "extraordinary confidence" in the company's performance and growth trajectory.

The Series F proceeds will fund expansion of enterprise services, deepen AI safety research and support international operations. In August, Anthropic released Claude Opus 4.1, which enhanced coding, reasoning and agentic task performance.

The model is available to paid users and integrated into platforms including Amazon Bedrock and Google Cloud Vertex AI.
