The Origin
From Sinquefield Cup
to Building a Platform
In September 2022, Hans Niemann sat across from Magnus Carlsen at the Sinquefield Cup in St. Louis and won. What happened next nearly ended his career. Instead, it became the reason Endgame.ai exists.
Carlsen, the reigning World Chess Champion, withdrew from the tournament the next day without explanation. What followed was months of accusation, speculation, and public scrutiny unlike anything competitive chess had ever seen.
Niemann maintained his innocence throughout. No definitive evidence of cheating during the Sinquefield Cup was ever produced. The lawsuit was eventually settled. But the experience raised a fundamental question: what happens when a single company controls the infrastructure of an entire sport?
Rather than campaign to reform a system he couldn't control, Niemann decided to build something new.
