Anthropic rattles software and finance stocks

Markets reacted sharply after reports around new Anthropic tooling, with a broad selloff across software, finance, and asset management names.

Bloomberg data showed heavy pressure across the sector:
� Around $285B wiped out across affected stocks
� Goldman’s software basket down about 6%, the largest drop since April
� Financial services index down roughly 7%
� Nasdaq at one point down 2.4%

The trigger was not a new model, but the release of 11 plugins for Claude Cowork on Jan 30. These tools target full workflows like financial modeling, legal research, and sales operations, rather than plugging into existing software.

Stocks tied to those workflows sold off hard:
� RELX: -14%
� Wolters Kluwer: -13%
� Infosys: -7%
� TCS: -6%

Wall Street has started calling it a “SaaSpocalypse.” The concern is that foundation model companies are moving beyond APIs and into owning the application layer itself.

For markets built on selling automation, this is no longer theoretical.
