How it works

The market resolves when the winner of the respective US Senate election designated by the market title is announced. Resolution will be based on the overall winner of the election, including any potential second round or run-off, as reported by a Source Agency. If the election designated by the market title does not take place, all corresponding contracts will resolve to "No". The official resolution sources are the agencies listed in Rule 14.65(c) in the CDNA Rulebook, which can be found at https://www.nadex.com/rules/. You receive a US$1 return per contract if your prediction is correct and nothing if it is incorrect. Liquidity may be low after the election results start coming in. Trading is temporarily paused during scheduled maintenance periods. Settlement Source: Rule 14.65(c) in the CDNA Rulebook. The notice of submission pursuant to CFTC regulation 40.2(a) for Rule 14.65 can be found at https://www.cftc.gov/filings/ptc/ptc11052532006.pdf Proposed Settlement: On or about Tuesday, November 3, 2026 at the close of polls (8:00 PM PST / 11:00 PM EST).
