Sora traffic share slips before shutdown

This looks less like a model-quality story than a distribution story: in consumer AI video, habit and shareable output matter more than raw hype.

• –Sora starts as the clear leader, then steadily gives way to Grok Imagine across the back half of the chart.
• –KlingAI, Veed.io, HeyGen, and RunwayML keep durable but smaller slices, which points to a fragmented market rather than a single winner.
• –Similarweb measures traffic share, so this is attention and discovery, not revenue or retention.
• –TechCrunch had already reported Sora downloads falling 45% month-over-month in January 2026, which lines up with the slide here.
• –OpenAI's retreat from a standalone Sora app suggests the company may prefer platform integration over a consumer social product.
