Dynatrace completes Arize acquisition, combining AI observability tools

Dynatrace says the acquisition combines Arize’s AI tracing, evaluation and experimentation capabilities with its observability platform.[2] The intended coverage spans development and evaluation through deployment, scaled operation and continuous improvement.[2] Dynatrace describes its platform as providing observability across applications, infrastructure, user experiences and business processes.[2] Together, these capabilities are intended to connect checks during AI development with visibility into deployed systems; the announcement describes that as a product direction, not a claim that all capabilities have already been integrated.[2][1]

Teams can inspect agent trajectories, model calls, retrieval, tool use, context, performance and cost.[2] They can also run evaluations and compare experiments.[2] Dynatrace says the combination is expected to help teams find AI issues earlier and resolve them faster.[1] Arize describes its platform as supporting continual learning for agents, while its automated monitoring and observability capabilities are intended to help detect emerging issues, troubleshoot causes and improve performance across traditional machine-learning and generative use cases.[1]

Dynatrace says Arize’s capabilities will be integrated into its platform over time.[1] In the meantime, Arize AX and the Dynatrace platform will remain available as standalone offerings, and Phoenix will continue as an open-source project.[2] Arize says Phoenix is built on OpenTelemetry and OpenInference, the latter described as an instrumentation project and conventions created by Arize for AI observability.[2] OpenTelemetry accepted a code grant of Arize’s OpenInference GenAI instrumentation in June 2026.[2]

Dynatrace’s completion announcement carried an October 1, 2026 dateline.[1] The announced transaction terms put the acquisition price at $915 million, subject to customary adjustments, including approximately $815 million in cash and replacement equity awards for Arize employees joining Dynatrace.[3] When the acquisition was proposed, Dynatrace expected it to be approximately 200 basis points accretive to ARR growth and to reduce fiscal 2027 non-GAAP operating margin by 175 basis points.[3] Dynatrace says the completed acquisition lets the teams begin turning their shared vision into a product and platform roadmap.[2]
