Build a Number of tropical storms model on this data
Every Number of tropical storms event lists a ladder of strikes — one contract per range — and the rung that settles in the money is the label, so the ladder's prices read as an implied distribution rather than one probability. The day bundle holds the full order-book path and trade tape of every rung, nanosecond-stamped; the statistics on this page cover the most traded contracts per day; the bundle holds every contract listed on Kalshi that day.
Split by release or event day, never at random — every rung of one ladder settles on the same print, so the whole ladder is one example; walk forward over releases. The ladder guide works distribution labels, cross-strike features and the link to the crypto strike grids through.
