Nintendo’s October 2026 online event is officially called the Mario Kart World Open October 2026—not “October Knockout.” It runs from October 17 to 18, and you can enter in-game with event ID 4450. It is a VS Race event and also serves as a qualifier for the Mario Kart World Fall Cup 2026.
When does the Mario Kart World Open start and end?
The event runs from October 17, 2026, at 2:00 p.m. Pacific Time through October 18, 2026, at 6:00 p.m. Pacific Time. It is a weekend event, not a single-day competition. Check Nintendo’s October event announcement for the schedule.

Nintendo of America listed the game’s regular price as $79.99 in its October 8, 2026 announcement. That is Nintendo’s listed regular price, not a current Amazon price. If you already have the required system, game and membership, you do not need to buy them again.
Who is eligible for the Fall Cup qualifier?
The October event is a qualifier for the Mario Kart World Fall Cup 2026, scheduled for December. The Cup rules limit eligibility to legal residents of the United States (including Washington, D.C.), Canada or Mexico, and participants must be in one of those territories while playing. The minimum age is 13 in the United States and Canada, and 18 in Mexico. A consistent, reliable high-speed internet connection is also required. See the official Fall Cup rules for the complete terms.
