Alt text (short for alternative text) is a written description of an image, used by screen readers to make web content accessible to blind users. It’s a core part of digital accessibility — but often missing or low quality.

This market will resolve to YES if, by June 30, 2026, a publicly available AI system can generate alt text that is judged equal to or better than human-written alt text for at least 90% of a diverse set of test images.

✔️ Resolution Criteria:

• A benchmark of at least 100 varied images (e.g. news photos, screenshots, memes, artworks, product images).

• Blind evaluators assess which description gives more usable, accurate, and vivid context.

• The evaluation must be replicable and published by a credible organization, researcher, or media outlet.

The AI system must be accessible to the public (via API, app, or website). Open-source or commercial tools both qualify.

I’m launching this as part of the Sight as a Service Forecast Hub, a series of prediction markets tracking key milestones in AI-powered accessibility for blind people.
