Recent polling aggregates for the 2026 Senate contests show Iowa’s open-seat race between Democrat Josh Turek and Republican Ashley Hinson remaining extremely tight, with averages near a one-point margin and frequent results within the margin of error across multiple surveys through mid-October. Maine’s contest pits incumbent Republican Susan Collins against Democrat Troy Jackson, where Jackson has held a steadier two-to-three-point edge in most recent polls. Iowa’s smaller and more volatile polling spreads, combined with its toss-up rating by forecasters, have produced the narrower expected margin that underpins the 61 percent trader consensus favoring Iowa as the closer race. No major candidate changes or late-breaking events have altered these patterns in the past month.
2026年中期选举计划于2026年11月3日举行。 如果 Iowa 按照既定安排举行的美国参议院选举中,未经四舍五入的胜选差距小于 Maine 的参议院选举胜选差距,则此市场的结果为“Iowa”。 如果 Maine 按照既定安排举行的美国参议院选举中,未经四舍五入的胜选差距小于 Iowa 的参议院选举胜选差距,则此市场的结果为“Maine”。 如果两个州的胜选差距相同,此市场将以 50-50 判定。 就本市场而言,“胜选差距”定义为得票数排名第一和第二的候选人所获有效票百分比之间的绝对差值。每位候选人所获有效票的百分比,将通过用得票数排名前两位的候选人各自获得的有效票总数,除以该次选举所有有效票总数来确定。 对于包含决选、排序选择投票或其他多轮投票的选举,相关胜选差距以决定胜者的那一轮为准。 如果截至 2027年3月31日 仍无法确定相关的胜选差距,则就本市场而言,该州的胜选差距将视为 0%。 本市场的结算来源将汇总所有负责认证全州选举的相关州选举机构资料;不过,也可以采用可信报道形成的共识。
