How This Market Settles

Tracks whether measurable precipitation falls in each of a panel of U.S. cities on a given day.

Settles on

Settles on total precipitation recorded at each city's official Weather Company station for that date; any amount strictly greater than 0 inches — including a 'Trace' reading — resolves Yes.

Structure

One event per day with a separate Yes/No outcome market for each city in the panel.
