SAP Just Picked Anthropic Over Microsoft. Here's Why.
At SAP Sapphire 2026 on May 12, CEO Christian Klein declared Anthropic's Claude the primary reasoning engine for 200+ AI agents and 50+ Joule Assistants inside S/4HANA, SuccessFactors, and Ariba. SAP runs 85% of the Fortune 500 — and just picked Anthropic over OpenAI despite Microsoft being its largest cloud partner. Why Anthropic won the largest enterprise vendor selection of 2026, the SaaSpocalypse context (SAP -41%, Anthropic at a $1T valuation 5x SAP's market cap), and two frameworks every CIO should run before signing a Joule contract: a Joule Investment Decision Matrix and a Vendor Co-Opetition Risk Matrix to assess partners who also compete with you.
