AI Agent Race: Anthropic & OpenAI Battle for Wall Street

Anthropic and OpenAI are in a rapid competition to embed AI agents on Wall Street. Within a 72-hour period in May 2026, both companies launched new initiatives targeting critical financial workflows. Anthropic announced a $1.5 billion joint venture with major financial firms. The company also released 10 finance agent templates with Claude Opus 4.7, its latest financial model. These templates cover tasks like pitch building and financial model creation. Claude now integrates with Microsoft Excel, PowerPoint, Word, and Outlook. It also connects to major market data providers. Claude Opus 4.7 is already in use at several large financial institutions. OpenAI responded with a $4 billion Deployment Company and an expanded partnership with PwC. This collaboration aims to build AI agents for the CFO's office. This intense 72-hour period shows the accelerating race to become the core operating system for the finance industry.
