> Dynatrace (NYSE: DT) announced it completed its acquisition of Arize, an AI observability and evaluation platform for continual learning on agents. Arize continues Phoenix (open source) and AX (enterprise); capabilities are expected to integrate into Dynatrace over time. Closing news for a deal announced August 13 — the completion release does not state a purchase price.

**Corrected October 14, 2026:** Removed an unverified ~$915 million purchase-price figure.

The August AI-observability deal just closed. Dynatrace now owns the eval loop that sits beside production telemetry for agent fleets.

**Dynatrace** (NYSE: **DT**) announced **October 1, 2026** that it has **completed its acquisition of Arize**, described as an AI observability and evaluation platform delivering continual learning for agents.

## Close vs announce

This is **closing news**, not a new deal announce. The acquisition was originally announced **August 13, 2026**. The October 1 completion PR **does not restate a purchase price**.

Customer/partner color in the completion PR includes quotes from **IDC**’s Stephen Elliot and **TELUS**’ Steve Tannock — standard close-day endorsements, not diligence findings.

## The GTM trade

Public-company consolidation of AI eval + production observability for agent fleets. This is the completion of the deal announced in August.

## Limits

- Completion, Phoenix/AX continuity, and integration-over-time language are from **Dynatrace’s October 1 press release** (mirrored on IR).
- Integration timelines and product unification remain forward-looking.
- No new product SKU or pricing in the completion release.
