# California Proposition 40 election: Yes vote percent

Live · $257 traded · listed on Kalshi

## About

The percentage is calculated as (total votes received by Yes on California Proposition 40 ÷ total valid votes cast on California Proposition 40) × 100, rounded to the specified decimal places. Total valid votes cast on the measure is the sum of Yes votes and No votes as reported by the California Secretary of State; ballots that record no vote on the measure are excluded from both the numerator and the denominator. Resolution is based on certified/official results only, not preliminary results. Invalid, spoiled, or rejected ballots are excluded from both numerator and denominator.
