Anthropic PBC is in discussions for a new funding round that could value the artificial intelligence company at over $900 billion, potentially making it the most valuable AI startup, surpassing OpenAI. Sources indicate that these talks are preliminary, with no offers accepted yet. Previously, Anthropic had turned down several funding proposals that valued it at $800 billion or more. The company, founded in 2021 by former OpenAI employees, has seen strong demand for its AI products, prompting it to consider an initial public offering (IPO) as early as October. Google has invested $10 billion at a $350 billion valuation and may invest up to $30 billion more if performance targets are met. Amazon has also committed $5 billion, with plans to increase its investment over time. Anthropic's recent introduction of the Mythos model, designed for cybersecurity, has raised safety concerns, limiting access to a select group of organizations. As Anthropic gains momentum, it is intensifying competition with OpenAI, which has faced challenges in meeting revenue and user growth targets, leading it to streamline its product offerings.
