How this market settles

Excerpt of the contract rules from Kalshi's public market data:

“If the total precipitation at KAPC in Napa in November 2026 through March 2027 is strictly greater than 10 inches, then the market resolves to Yes. The total is the sum of The Weather Company's daily precipitation values at KAPC from November 1, 2026 through March 31, 2027, inclusive, using its reporting days. If The Weather Company publishes a total for that exact period, that total takes precedence. Data: https://weather.com/kalshi.”
