AT&T taps OpenAI to power its in-house legal team
The telecom giant is pairing its LegalEdge practice with AI chatbots and agents as it plans to trim its outside law firm roster
AT&T is bringing OpenAI into the legal department. The telecom company announced a partnership with the AI developer, reported on October 8, 2026, to rework how its lawyers handle legal work using AI tools such as chatbots and agents.
The goal is to rely less on outside law firms.
The deal builds on LegalEdge, the dedicated in-house law firm AT&T launched in January 2026. The partnership adds AI to a team that was already set up to pull work away from external counsel.
What AT&T is actually building
LegalEdge launched with approximately 38 legal professionals. Before that, AT&T tested the idea with a smaller pilot team of 24-30 people.
The group works as an internal practice group. It collaborates with outside counsel rather than replacing them outright, while deploying AI tools across its work.
The OpenAI partnership targets a specific problem: institutional memory. AT&T has more than a century of legal knowledge, and the plan is to make that history easier to search and use.
The company says the integration should streamline routine legal work.

AT&T has already moved in this direction. Throughout 2026, the company has shifted thousands of hours of traditional law-firm work to its internal team.
The law firm roster is about to get smaller
The most consequential detail concerns AT&T’s outside counsel. General Counsel David McAtee said the company aims to cut its roster of national law firms from around 30 to 18-20 over the next two years.
McAtee also said AT&T plans to reward the firms that adopt AI in their own practices.
McAtee highlighted the potential for additional cost efficiencies from bringing AI into the legal function. He also pointed to improved access to the company’s accumulated legal knowledge as a key benefit.
Why corporate legal departments are watching
AT&T built the team first, piloting with 24-30 people and expanding to around 38. Only then did it layer in AI from a major developer.
The company has already redirected thousands of hours of work in-house this year, before the OpenAI integration fully kicks in.
What this means for the legal industry
For outside law firms, AI adoption is becoming a factor in who gets work from AT&T. The company has said it will reward AI adopters while trimming its roster.
For OpenAI, the deal is a showcase in a high-stakes professional field. Legal work demands accuracy, confidentiality, and careful handling of sensitive information.
The key markers over the next two years are whether AT&T actually trims its roster from around 30 firms to 18-20, and whether the promised cost savings and knowledge gains appear.
