Trading on Kalshi involves risk and may not be appropriate for all. Members risk losing their cost to enter any transaction, including fees. You should carefully consider whether trading on Kalshi is appropriate for you in light of your investment experience and financial resources. Any trading decisions you make are solely your responsibility and at your own risk. Information is provided for convenience only on an "AS IS" basis. Past performance is not necessarily indicative of future results. Kalshi is subject to U.S. regulatory oversight by the CFTC.

Important information: Kalshi has filed an amendment to this market's Contract that allows it to settle before February 1, 2027, starting November 26, 2026, once Associated Press race calls have decided the outcome with a buffer for post-election changes. For positions held at 7:00 AM ET on November 12, 2026, if those positions would have been resolved in a trader's favor under the February 1, 2027 composition of Congress but early settlement changes that result, Kalshi will credit $1 per Contract held out of its own funds. A clarification for this market has been posted below.
