“With an AI Impact Index rating of 89, Deutsche Telekom Group leads the AI-Leading band globally”

This Appledore Research Market Signal Analysis updates our AI Impact Index assessment of Deutsche Telekom following its AI Investor Day in Bonn (October 2026). For the first time, we score DT as a Group, including T-Mobile US, because the company now presents AI as a single programme spanning Germany, its European operating companies, T-Systems and the US.

We grade DT against our ATLAS framework’s six weighted dimensions, from strategy and execution to efficiency outcomes, revenue innovation and AI infrastructure. We set out what moved the score, how the Group and component scores relate, and how DT stacks up against its German and global peers. We also take a candid look at what management would not commit to, and what DT still has to show in its reported results.

This update is for CSP strategy teams, telecom vendors and investors who want an independent, evidence-based benchmark of the operator now setting the pace on AI in telecom.
