We’re two weeks away from the 2026 Midterm Elections, and the on-air propaganda isn’t the only thing heating up.
Wagers at BetOnline are flooding in by the minute, and we have some important Senate updates to relay.
Below, you will find the latest odds and implied probabilities for each of the 35 Senate races. Of those, 25 have over/under projections for the favorite’s margin of victory.
Former Rep. Mary Peltola, a Democrat, is now listed at -325 to win the Alaska senate race. Her race is generating some of the highest betting interest, and with good reason. Peltola raked in $17 million over the last three months, her campaign shared first with POLITICO, a sizable haul for the Democratic challenger in one of the biggest Senate battlegrounds.
It’s Peltola’s largest quarterly fundraising total in her bid to oust GOP Sen. Dan Sullivan. Her campaign also said it’s a record third-quarter sum for a Senate candidate in Alaska.
House of Representatives odds will be updated later today (October 20, 2026).
