The Iowa Electronic Markets is a futures market run for research and teaching purposes. Traders can buy and sell real-money contracts based on their belief about the outcome of an election or other event. Using this "wisdom of crowds," the price of a contract at any given time is a forecast of the outcome.

Correction of typo for SENATE26 contact
The description of the RS.hold26 contract was corrected from "fewer than 53 seats" to "fewer than 54 seats" due to a typo in the original description. Therefore, if the Republicans have 53 Senate seats after the 2026 election, the contract RS.hold26 will pay $1 and all others will pay $0.
