Jannik Sinner just won the 2025 Australian Open, setting him up to potentially win all four Grand Slams this year. Currently (2025-01-26 22:05:59 UTC), Manifold is predicting 24% for the French Open, 31% for Wimbledon, and 29% for the US Open. Simple multiplication (assuming no correlation, which I highly doubt) would indicate a 2.16% chance of winning all four. What do you think?
Rules:
This seems pretty non-subjective, so I may bet in this market.
Close date may be adjusted to reflect schedule changes.
If for any reason one of the tournaments does not play in 2025, but is played later and considered the "2025" make-up tournament, it will count, and the close date will be extended.
If a tournament is cancelled altogether, resolves N/A.
Feel free to ask clarifications!
