Tournament Structure

The Metaculus Cup will run three tournaments annually—spring, summer, and fall—each lasting four months. Every Monday, we'll launch new questions covering current events and engaging forecasting challenges.

Each Friday at 17:00 UTC, an average of 4 questions will be set to "Upcoming," opening three days later. This gives forecasters time to prepare and provide feedback. Breaking news may result in additional questions being launched during the week. Questions will frequently close early, though some might remain open for the entire tournament duration.

Prize Structure

This tournament features a $5,000 prize divided into two distinct prize pools:

Forecasting Prize ($3,500)

The forecasting prize will be based on time-averaged scores, rewarding accuracy and consistency in your predictions.

Commenting Prize ($1,500)

The commenting prize will be distributed to the 10 best comments made on Metaculus Cup questions before the end of the tournament. Prizes will be awarded as follows:

• 1st: $300
• 2nd: $250
• 3rd: $200
• 4th: $150
• 5th-10th: $100 each

Metaculus will select top comments that showcase some or all of these qualities:

• Provides clear and insightful reasoning
• Contributes valuable information
• Identifies mistakes in the community's prediction or makes a strong case for a different prediction
• Identifies key factors and submits them using the new key factors feature
• Receives "Changed My Mind" votes or has key factors rated as significant by the community

Comments don't need to predict accurately to win prizes—even directionally incorrect comments can be rewarded based on the strength of their reasoning. Individual commenters can receive multiple prizes but will be capped once they reach or surpass $750 in total winnings.

The Metaculus Cup welcomes question submissions from the community! Writing intriguing questions that attract forecaster engagement helps our forecasting community grow and keeps Metaculus ahead of breaking news. You can find our question writing guide here.
