OpenAI kills Sora

SORA LAUNCHED in September 2025 to the kind of breathless reception that Silicon Valley reserves for its most photogenic creations. OpenAI's AI video generator briefly hit number one in the Apple App Store, racked up four million downloads within a month, and landed a $1 billion licensing deal with Disney — the first time the Mouse House had ever handed its intellectual property to an AI platform. By December, more than 200 animated characters from Disney, Marvel, Pixar, and Star Wars were available for users to drop into AI-generated clips. Bob Iger called it "breathtaking growth." Sam Altman called Disney "the global gold standard for storytelling." Hollywood appeared to be embracing the machine. It was, by any measure, a spectacular debut. It lasted roughly six months.

On Tuesday, Altman told staff that the company would wind down the Sora consumer app, discontinue its developer API, and drop video functionality from ChatGPT entirely. The decision is part of a broader consolidation ahead of a potential IPO as early as the fourth quarter of 2026, in which OpenAI is merging ChatGPT, its Codex coding platform, and the Atlas browser into a single desktop "superapp" aimed squarely at enterprise productivity. Fidji Simo, OpenAI's chief of applications — hired from Instacart in May 2025 to impose product discipline on what had become a sprawling portfolio — framed the retreat with characteristic startup candor: the company could not afford to be distracted by "side quests" while Anthropic was eating its lunch in the enterprise market. According to an Axios analysis, Anthropic now captures roughly 73% of first-time enterprise AI spending. Claude overtook ChatGPT as the most-downloaded app in the United States in March 2026. Side quest, indeed.

The Sora shutdown is not an isolated product decision. It is the culmination of a strategic reckoning that has been building inside OpenAI for months. The company reported 900 million weekly active users as of February 2026 — more than double its figure from a year earlier — but that colossal reach was spread across too many parallel tracks, none of which were executing at the quality level leadership wanted. Simo's internal memo was blunt: "We realized we were spreading our efforts across too many apps and stacks, and that we need to simplify." In OpenAI's taxonomy, Sora was not killed for being bad. It was killed for being expensive and irrelevant to the business that will actually go public.

Lights, camera, no traction

But Sora's demise is more than an internal housekeeping decision at one company. It is the sharpest signal yet that AI-generated video — the technology that was supposed to remake Hollywood by the end of the decade — has collided with the twin constraints of economics and indifference. The economics are punishing. Estimates compiled by Forbes and analyst Deepak Mathivanan of Cantor Fitzgerald suggest OpenAI was spending approximately $15 million per day to power Sora, annualizing to more than $5.4 billion. Each ten-second clip cost around $1.30 in raw GPU time, requiring roughly 40 minutes of total GPU computation — or eight to ten minutes split across four GPUs running in parallel. Assuming even a quarter of Sora's 4.5 million users were active and posting an average of ten videos daily, the platform was churning out more than 11 million videos a day. Altman himself conceded that users were mostly "making funny memes to send to their three friends" — a use case for which, as he put it, no advertising model can cover the cost.
