The two leading U.S. betting markets show the Democrat U.S. Senate candidate in Maine shellacking the veteran Republican incumbent.
Polymarket is giving Democrat Troy Jackson 69-33 odds over Susan Collins, while Kalshi has it at 64-36.
Effectively, bettors are predicting roughly a 2:1 chance of a Jackson victory.
The markets measure odds as opposed to the actual margin of victory or loss.
The market predictions come amid a left-wing PAC survey showing Jackson with a low-single-digit lead.
The betting markets are reflecting what they portrayed as similar odds for Graham Platner before he withdrew as the Democrat nominee following serious allegations of misogynistic behavior towards women.
Jackson became the default candidate after the Maine Democrat Party caucus selected the former state senate president to compete against the five-term Collins.
Hart Research’s recent poll done for Senate Majority PAC gave Jackson a far-more conservative 4-point victory over Collins, as reported Thursday by The Maine Wire.
