Italy Antitrust Probe Hits Microsoft 365 AI Bundling, Shares Fall 3.46%

Italy’s antitrust authority opened an investigation on June 26, 2026, into Microsoft over alleged unfair commercial practices linked to Microsoft 365 price hikes. Regulators claim the company bundled Copilot and Designer AI tools without clear disclosure and automatically shifted customers to costlier subscriptions unless they opted out. Microsoft shares dropped 3.46% to 352.83 on the news, reflecting immediate market pressure. The probe raises regulatory risks around subscription pricing, consumer consent, and AI monetization across Europe, though direct financial impact remains unquantified.
