El‑Sayed's Michigan Senate odds climb to 76%, Kalshi shows
Kalshi reports a historic high for El‑Sayed as early voting continues across Michigan.
Key Takeaways
- Kalshi's predictive market places Abdul El‑Sayed's chance of winning the Michigan Senate seat at 76%.
- Mike Rogers's probability on Kalshi fell from 35% at the week's start to 24% by Friday afternoon.
- Early voting in Michigan runs through 1 November, and 22% of nearly 8.4 million registered voters had voted early.
- High-profile Democratic support — including $1 million donations from Bernie Sanders and Alexandria Ocasio‑Cortez and campaigning by Barack Obama — coincided with El‑Sayed's odds rising.
Predictive market-implied odds that Abdul El‑Sayed will win the Michigan Senate race rose to 76%, a record high for El‑Sayed and the highest Democratic level in nearly six months, Kalshi reported on 30 October 2026. Republican Mike Rogers fell to 24% on Friday afternoon, down from 35% at the start of the week, according to Kalshi's Michigan Senate contract.
Context and calendar
The market on the platform had been kept live before El‑Sayed won the Democratic nomination on 4 August; at that time the contract still tracked a generic Democratic victory. Early voting across Michigan runs through Sunday 1 November. So far, 22% of nearly 8.4 million registered voters — fewer than 1.9 million ballots — have cast early votes, NBC News reported citing TargetSmart data.
Endorsements and funding
The rise in El‑Sayed's odds coincides with increased public support within the Democratic Party. The congresswoman he defeated in the primary, Haley Stevens, will campaign with El‑Sayed in Detroit this weekend; it will be their first joint public appearance in several months, The Associated Press reported. Bernie Sanders contributed $1 million via a transfer to support the campaign and appeared in Ann Arbor on Tuesday at an event titled “Students vs. Billionaires” urging students to vote. Former president Barack Obama campaigned with El‑Sayed in Detroit the prior weekend. Representative Alexandria Ocasio‑Cortez campaigned this month and donated $1 million to a fund supporting an El‑Sayed victory, the largest personal donation she has made, The New York Times reported.
“Whether Dr. El‑Sayed wins or loses — and by how much — will set the parameters of the ideological and political debate heading into one of the party’s most wide-open presidential races in memory,” The New York Times said.
Senator Ted Cruz of Texas said that if El‑Sayed wins Michigan, the Democratic presidential nominee in 2028 would be Alexandria Ocasio‑Cortez, The New York Times reported. In Kalshi's contracts on the 2028 Democratic presidential candidate, California Governor Gavin Newsom has the highest probability at 18%, followed by Senator Jon Ossoff at 16% and Ocasio‑Cortez at 13%.
Polls and market predictions
A CNN poll found 49% of likely voters in Michigan leaning toward El‑Sayed versus 42% for Rogers, a seven-point lead greater than the survey's margin of sampling error of 4.7 points. The poll was conducted by the nonpartisan firm SSRS between 20 and 27 October.
A Mitchell Research & Communications survey, conducted 26–27 October for CBS Detroit, put El‑Sayed seven points ahead of Rogers, above the margin of error of 3.9 points. Kalshi traders expect an El‑Sayed win by three points.
