The Mario Kart World Open October 2026 starts Saturday, October 17 and runs through Sunday evening in the United States. The event is an online qualifier for December’s Mario Kart World Fall Cup, and the code you need to find it is 4450.
Here are the converted US times and the setup steps Nintendo places deeper in its announcement.

Event ID and how to enter

- Select Online Play from the main menu.
- Press the minus button to search for an event.
- Enter Event ID 4450.
- Join during the event window and begin racing.
Nintendo’s official Mario Kart World Open rules and announcement are the primary source for the code, schedule, eligibility, and settings.
What you need before you race
You need a Nintendo Switch 2, Mario Kart World, a Nintendo Account, internet access, and an active Nintendo Switch Online membership. Nintendo mentions a free seven-day trial for eligible accounts, but the trial converts to a paid individual membership unless automatic renewal is turned off.
The competition is open to eligible players in the United States, Washington, D.C., Canada, Mexico, and other listed North and South American territories. The official rules set a minimum age of 13 in the US and Canada, while entrants in Mexico must be at least 18. Minors need permission from a parent or legal guardian.
Race settings and how qualification works
The event uses VS Race at 150cc with normal items, no teams, no COM racers, and connected courses. There is a 30-second interval between races, and each player can count a maximum of 32 races.
The top 24 eligible players in the qualifying event advance to the Mario Kart World Fall Cup scheduled for December. Because the field is ranked over many races, consistency matters more than one perfect finish. Avoid quitting after a poor result, and make sure your connection is stable before starting a long session.
Participation reward
Eligible participants who complete the required entry process can receive 50 My Nintendo Platinum Points. Nintendo says the points should be distributed around October 27. They are a participation reward, not a prize reserved for the top 24.
Public results may display a qualifying player’s Nintendo Account username, user icon, and score. Check your public profile details before competing if you do not want an old username shown on the results page.
Quick preparation checklist
- Update the game and console before the start time.
- Confirm Nintendo Switch Online is active.
- Use Event ID 4450, not a room code from social media.
- Test your controller and internet connection.
- Leave enough time for multiple races before the event closes.

Bottom line: enter through Online Play with Event ID 4450 between 2:00 p.m. PT on October 17 and 6:00 p.m. PT on October 18. Meet the account and membership requirements, then use the 32-race limit to build the strongest score you can.
