Amish Shah holds an 83% implied probability in trader consensus for Arizona’s 1st Congressional District because nonpartisan forecasters rate the open seat Lean Democratic or Tilt Democratic following Republican incumbent David Schweikert’s retirement. Shah, a former state legislator and emergency physician who narrowly lost the seat in 2024, benefits from polling averages showing a modest lead among likely voters and strong independent support in the suburban Phoenix district. Recent developments include heavy Republican outside spending exceeding $22 million and President Trump’s personal endorsement of Jay Feely, a former NFL kicker and longtime associate, yet these efforts have not altered the market positioning ahead of the November 3 election. Key campaign issues such as data-center development, water policy, and affordability continue to define voter distinctions in the swing contest.
