According to OpenAI's official help center and reporting by MiraFlow, OpenAI discontinued Sora on March 24, 2026, shutting down web and app access on April 26. The economics were stark: the AI video tool burned an estimated $15 million per day in compute costs while generating only $2.1 million in total lifetime revenue. Active users had dropped from over one million downloads in its first week to under 500,000. Persistent physics glitches made the $200 per month Pro tier hard to justify, and legal exposure over training data added further pressure. OpenAI is redirecting freed compute toward a next-generation language model and enterprise infrastructure ahead of its anticipated IPO. Google's Veo 3.1, Runway's Gen-4.5, and Kling 2.5 are positioned to absorb Sora's user base. The Sora API closes September 24, 2026.
