About this market
Final prediction market prices for "Who will vote "Yea" on the DHS Appropriations Act, 2026 by March 31?". Dick Durbin last traded at 0.1%. Next is Maggie Hassan at 0.1%. $111K has traded across 2 outcomes on Polymarket. The market closed on Mar 31, 2026.
This market will resolve to "Yes" if the listed U.S. senator votes "Yea" on passage of the Department of Homeland Security Appropriations Act, 2026, during the first roll-call vote on passage in the U.S. Senate. Otherwise, this market will resolve to "No". This market will resolve to "No" if no vote on passage of the Department of Homeland Security Appropriations Act, 2026, occurs by March 31, 2026, 11:59 PM ET. The listed senator's vote during the first qualifying roll-call vote on passage of the Department of Homeland Security Appropriations Act, 2026, will be used for this market’s resolution, regardless of whether that bill is later signed into law. Any vote by the listed U.S. senator on the Department of Homeland Security Appropriations Act, 2026, whether that bill is voted on individually or as part of a larger legislative package in which DHS appropriations are clearly included, will qualify for this market’s resolution. Any vote on a continuing resolution (CR), whether or not it includes Department of Homeland Security funding, will not qualify for this market’s resolution. The primary resolution source for this market will be official information from the U.S. Government. However, a consensus of credible reporting may also be used.
Questions
What does the consensus price mean?
It is the price of a Yes contract that pays $1 if the outcome happens. A 14¢ price means traders put the chance near 14%. Where two venues list the same outcome, we blend their last prices, weighting the venue with more trading volume more heavily (neither counts for less than a quarter). When only one outcome can win, each venue’s prices add up to a little over 100% (its margin); the fair chance removes that margin so the outcomes add up to exactly 100%.
How is the payout worked out?
A Yes contract pays $1 if it wins, so at the best ask a $100 stake buys 100 ÷ ask contracts. At 18¢ that is about 555 contracts, paying $556 (5.56x) if Yes happens. Venue fees and price slippage on larger orders are not included.
Why do the venues show different prices?
Each venue has its own traders, fees and order book. Contracts can also settle on slightly different terms, which is why each row lists how closely the rules match.
Is a price gap an arbitrage?
Only when you can buy Yes on one venue below what someone pays for Yes on the other, after fees, and both contracts settle the same way. We show the executable bid and ask so you can check.
How fresh are these prices?
Venue prices refresh every few minutes, and the order book and live quotes stream continuously. Each venue’s card shows when we last observed it.
