Anthropic Unveils Claude Opus 4.6; Financial Software Stocks Drop

Anthropic released Claude Opus 4.6 on February 5, 2026, enhancing coding, multi-tasking, and long-running operation capabilities, with improved financial analysis from large document reviews. The update intensified investor concern about AI replacing traditional financial information services, sending software stocks lower on the same day. FactSet Research Systems (FDS-US) fell 10% in mid-trading to a 20-month low, closing 7.21% lower; Thomson Reuters (TRI-US) dropped over 8.5% to a 2020-03 low, closing 5.61% lower. S&P Global (SPGI-US), Moody's (MCO-US), and Nasdaq Composite (NDAQ-US) also declined. Claude Opus 4.6 can significantly shorten days-long financial research workflows, excelling in coding, debugging, long-codebase stability, and structured financial analysis. It leads the Finance Agent benchmark. Over 300,000 enterprise customers use Anthropic’s models, with roughly 80% of revenue from enterprise clients. The company is expanding into cybersecurity, life sciences, healthcare, and finance, and is in discussions for a $350B valuation round, alongside OpenAI’s potential $830B valuation. OpenAI also updated Codex, extending its capabilities beyond code writing and debugging to document, slide, and user data analysis. While some industry leaders argue legacy software firms with strong data assets and AI integration can still compete.
