AI Made Chess More Popular, Not Less

💡Chess.com shows how AI can turn a solved skill into a larger, more engaging product ecosystem.
⚡ 30-Second TL;DR
What Changed
Chess.com reached 250 million registered users, over 10 million daily active users, and more than $200 million in annual revenue by 2026.
