Anthropic's impressive $5 billion annual revenue is significantly dependent on just two major clients: Cursor and GitHub Copilot. This concentration poses a risk, particularly as OpenAI's GPT-5 emerges as a strong competitor, potentially undercutting Anthropic's Claude model. Should these key customers migrate to GPT-5, Anthropic's revenue could be significantly impacted.
The AI landscape is witnessing an intense pricing war, putting pressure on margins. While Anthropic currently leads in API revenue, driven by its Claude Sonnet 4 and Opus 4 models, OpenAI is rapidly gaining ground with consumer subscriptions and business clients. The upcoming release of GPT-5 is expected to further intensify competition, challenging Claude's dominance, especially in coding tasks.
Anthropic is actively working to solidify its position through model upgrades and new features like Subagents in Claude Code. These sub-agents are pre-configured AI personalities designed to handle specific tasks, potentially enhancing the platform's appeal and retaining its customer base. The company aims to reach $9 billion in annual revenue by year-end, but its ability to diversify its customer base and maintain a competitive edge against OpenAI will be crucial for achieving this goal.
