Anthropic's 'Cowork' Update Ignites Enterprise Software Stock Rally - These Stocks Surge

On Tuesday, stocks of several enterprise software and data providers jumped following a product announcement from AI startup Anthropic. Anthropic Names New Enterprise Connector Partners On Tuesday, Anthropic published a blog post detailing major updates to Cowork, its enterprise AI platform, and its plugin ecosystem. The post announced that new connectors from enterprise software providers are now available, explicitly listing Google Workspace, Docusign, Apollo, Clay, Outreach, Similarweb, MSCI, LegalZoom, FactSet, WordPress, and Harvey as available integrations. The announcement also named Slack by Salesforce, LSEG, S&P Global, Apollo, Common Room, and Tribe AI as companies that have built plugins for joint customers. What Anthropic’s Cowork Update Covers Anthropic’s introduces several enterprise capabilities. Admins can now build private plugin marketplaces within their organizations, set up plugins from starter templates or from scratch, and manage connectors through a new unified menu called “Customize.” The post notes that Claude can also now “orchestrate across Excel and PowerPoint, working end-to-end and passing context between apps,” currently available as a research preview for all paid plans on Mac and Windows. New pre-built plugin templates were also announced for HR, Design, Engineering, Operations, Financial Analysis, Investment Banking, Equity Research, Private Equity, and Wealth Management functions. Anthropic Has Been Moving Fast The Cowork announcement comes amid a busy stretch for Anthropic. On Monday, shares of International Business Machines Corp (NYSE:IBM) fell 13.18% after Anthropic said its Claude Code tool can help companies modernize legacy COBOL systems — a market IBM has long served. On Friday Anthropic's Claude triggered an “AI Ghost Trade” in the cybersecurity sector, causing sharp declines in major stocks like CrowdStrike Holdings Inc (NASDAQ:CRWD), Palo Alto Networks Inc (NASDAQ:PANW), and Zscaler Inc (NASDAQ:ZS). Investors have grown concerned that rapid advances in AI-driven security tools could bypass or disrupt traditional “legacy” cybersecurity vendors. However, Wedbush analyst Dan Ives argues this selloff reflects panic rather than fundamentals, stating that AI actually represents the “biggest total addressable market opportunity” in the industry’s history. Price Action: Similarweb shares were up 3.33% at $2.60, FactSet Research Systems shares were up 6.27% at $202.19, Docusign shares were up 3.75% at $42.27 and Salesforce shares were up 4.41% at $186.02 at the time of publication on Tuesday, according to Benzinga Pro data.
