New! Announcing the M5 Forecasting Competition
March 2 to 30 June 2020
The M5 Competition is the latest of the M Competitions. The competition will use actual/authentic data made generously available by Walmart and will be implemented using Kaggle’s Platform. Given the large number of companies that have already shown interest in participating and the substantial $100,000 prize money, we estimate that the M5 Competition will attract more than 2,000 participants and teams to compete as well as a number of invited companies. More information coming soon.
