CROSS-CATEGORY: The Agent Layer Is Being Bought, Not Built — A June M&A Wave Sees Incumbents and Infra Giants Acquire the Interface

Within a single week, Salesforce bought Fin/Intercom ($3.6B, support), SpaceX bought Cursor ($60B, devtools), and Asana acquired no-code agent-orchestration platform StackAI — three unrelated categories where the buyer chose acquisition over organic build to own the agent surface. The pattern signals that as AI-native challengers reach distribution scale, the cheapest path to the 'system of record for agents' is a checkbook, not a roadmap. Expect more category leaders to convert from defenders into acquirers.
