Bellevue, Wash. and Bonn, Germany — January 29, 2026 — T-Mobile US (NASDAQ: TMUS) and Deutsche Telekom today announced the 12 finalists for the sixth annual T Challenge competition. This year’s global competition focuses on a singular, transformative vision: building the AI-native telco—an autonomous, customer-focused, and intent-based network ecosystem.
Following a rigorous review of submissions from around the world, the selected teams now enter the “Development Phase,” where they will refine their AI-driven prototypes alongside experts from both T-Mobile and Deutsche Telekom. These innovators are competing for a slice of a €300,000 (or U.S. equivalent) prize pool and the opportunity to see their solutions deployed on America’s Best Network and the most awarded Telekom networks across Europe.
