The Department of Justice (DOJ) scheduled a major discovery update for January 16, 2026, in its ongoing antitrust lawsuit against Visa. This update marks a key development in the legal proceedings.

The suit alleges the payments giant established an illegal monopoly in the U.S. debit card market. Visa simultaneously navigates a challenging regulatory environment.

Analysts describe the current situation as a "perfect storm." Visa's stock faced pressure, recording a significant drop in early January. This legal challenge, combined with political discussions regarding credit card fees, contributes to investor uncertainty across the payment processing sector.
