Who will win the Michigan Senate race? Democrat Abdul El-Sayed is the favorite, but not a heavy one. As of September 20, Kalshi has El-Sayed at 64 to 66 cents to beat Republican Mike Rogers on November 3, and a 65-cent midpoint means the market gives him a 65% chance. Our price-blind AI panel, which scores the race without seeing the market, has it closer at 54-46 El-Sayed.
The two numbers moved together in August. A Susquehanna poll taken August 11 to 17 had El-Sayed up seven, the polling average swung from a Rogers lead back to roughly a tie, and Kalshi pushed El-Sayed to a 60-cent favorite. The panel, re-scored on the new polls, moved up from a coin flip but stopped short of the market, and the market has since kept climbing without it, with a dip to 57 and back in mid-September. That eleven-point gap is what the rest of this page is about.

What Moved Since September 17
Rogers had a bounce that did not hold, and El-Sayed ends the window a cent better on the ask. El-Sayed was 64 to 65 cents on Thursday, September 17, and is 64 bid, 66 ask now, with the last trade at 66, the top of a 63-to-66 range. Rogers went from 35 to 36 up to 38 on Thursday night and Friday, and was back to 34 by Saturday night.
- A Fifth Straight Poll Has El-Sayed Narrowly Ahead. InsiderAdvantage, fielded September 16 to 18 among 1,200 likely voters, had El-Sayed 47, Rogers 45. Since Glengariff's Rogers lead at the start of the month, CNN, Trafalgar, Emerson, the Post and now InsiderAdvantage have all had El-Sayed up, and all five by one to three points.
- The Average Still Tightened. The PollingSource 30-day average read El-Sayed 46.7 to Rogers 44.9 at the September 20 fetch, seven polls, against 46.9 to 44.7 on September 17. That is the second stamp in a row where the average narrowed, from +3.1 to +2.2 to +1.8, while the price edged up, from 63-64 to 64-65 to 64-66. The market is paying for the consistency of the lead, not its size.
- No Handicapper Moved. Cook, Sabato and Inside Elections still list a Toss-up, per PollingSource. Decision Desk HQ's forecast updated on September 18 and has El-Sayed at 67%, the same number this page recorded on September 17.
The next scheduled thing that can move this is the October 8 debate. The September 7 to 17 stretch below is where the real movement was.
What Moved From September 7 To September 17
The price went down before it went up. El-Sayed's contract, 63 to 64 cents at the September 7 stamp, slid through the middle of the month and touched 57 on Sunday, September 13, before a rally on Wednesday, September 16, carried it to 64 to 65. Rogers traced the mirror image, 36 to 37 up to a 41-cent peak and back to 35 to 36.
- Rogers Was Bid Up First. From Thursday, September 10, through Sunday, September 13, Rogers climbed from 37 cents to 41, and late on Sunday afternoon El-Sayed dropped from 61 to 57, the low of the whole window. It was back to 61 within the hour.
- The Polls Around The Start Of That Window Included The Only Rogers Lead Of The Month. Glengariff for The Detroit News, fielded August 31 to September 3 among 600 likely voters, had Rogers 45.8 to 44.4, the only poll in the current 30-day window with him ahead. CNN's poll, as reported by Newsweek, fielded August 31 to September 6 among 843 likely voters, had El-Sayed 47 to 44, and Trafalgar, a Republican pollster, had El-Sayed up one, 46 to 45, on September 7 to 9, per PollingSource.
- The September 16 Rally Came With A Debate Fight And An Endorsement, Not A Poll. On September 15 Rogers skipped a Fox 2 Detroit town hall with El-Sayed, saying "We never agreed to it"; his campaign separately accused the moderator of favoritism and says it remains committed to the two scheduled debates, October 8 and October 21. On September 16 The Detroit News endorsed Rogers, calling him "clearly the best choice." That same day El-Sayed's contract went from 62 to 65 and Rogers slipped from 37 to 36. I cannot tell you which of those a Wednesday buyer was trading on.
- The September 17 Polls Landed On El-Sayed's Side. Emerson, fielded September 12 to 14 among 1,000 likely voters, had El-Sayed 48, Rogers 46, with what Emerson's executive director, Spencer Kimball, called "a substantial educational divide": Rogers 48 to 45 among voters without a four-year degree, El-Sayed 53 to 42 among graduates. A Washington Post-Schar School poll, as reported by the Washington Examiner, released the same day had him up 48 to 45 among likely voters. The PollingSource 30-day average read El-Sayed 46.9 to Rogers 44.7 at the September 17 fetch, seven polls, against 47.0 to 43.9 on September 7. Both polls had El-Sayed ahead, but the 30-day average narrowed over this stretch, from El-Sayed +3.1 to +2.2, as Glengariff and Trafalgar rolled in and the two new polls came in under the old average. The market repriced up a cent into an average that moved a point the other way. The Detroit Regional Chamber PAC endorsed Rogers the same day.
The week before the September 7 stamp did the bigger work. From August 27 through September 1, a repricing took the board from 60-61 to 63-64. EPIC-MRA, fielded August 22 to 28 among 600 likely voters, had El-Sayed 47 to 43, and Michigan State University's State of the State survey, fielded August 10 to 20 with YouGov, had him 48 to 44 among registered voters and 50 to 45 among likely voters, with director Matt Grossmann noting Rogers "is running ahead of James, with more success among independents." Both campaigns agreed to an October 8 debate in late August and a second, October 21, on September 2.
The panel's 54 is frozen at its August 20 run. It has not seen EPIC-MRA, MSU, Glengariff, CNN, Trafalgar, Emerson, the Post or InsiderAdvantage, seven of which have El-Sayed ahead and one of which has Rogers. Its own August note said a run of polls in one direction would pull it toward the market. The run arrived, the market kept climbing, and the 54 could not move. That is part of the reason the gap has grown from six points on August 20 to 11 today.
What Moved In August
On August 5, the day after the primary, the exchange had El-Sayed at 62.5 cents and the panel scored a coin flip. By August 18 the first post-primary polls had favored Rogers and the market had drifted El-Sayed down to 56.5 cents. Then the polling turned.
- A Fresh Poll Flipped The Average. Susquehanna Polling and Research, a pollster PollingSource labels Republican-aligned, surveyed likely voters August 11 to 17 and had El-Sayed 46, Rogers 39, with 91% of Democrats behind their nominee. It was the clearest sign at the time that the party had consolidated after a bruising primary.
- The Average Followed. The PollingSource 30-day aggregate, which includes partisan and sponsored polls, read El-Sayed 44.8 to Rogers 44.4 at the August 20 fetch, after carrying a roughly four-point Rogers edge two weeks earlier.
- The Market Repriced In A Day. El-Sayed's contract climbed from a 56.5-cent mid to 60.5 cents.
What Decides This Race
Six facts pull against each other.
The freshest polls favor El-Sayed. The fuller record at the August 20 run still favored Rogers. Susquehanna had El-Sayed up seven, GBAO, a Democratic firm, had him up six among likely voters a week earlier, and TIPP had him up four among registered voters, 43-39. Against that, the Beacon Research and Shaw poll for Fox News through August 10 had Rogers up four, and the ToWin poll completed August 14 also had Rogers ahead.
Averaged across the non-partisan head-to-heads the seats saw at the August 20 fetch, Rogers led by about three. Averaged across only the month before that fetch, the two were tied. The trend has bent toward El-Sayed since, while the level stays close.
The Democrat who polled better against Rogers is the one who lost. Through the primary, Haley Stevens ran roughly even with Rogers in the same pollsters' head-to-heads while El-Sayed trailed by about three. Michigan Democrats nominated the weaker general-election poller by about 15,000 votes. The bearish seats keep returning to that gap, and the consolidation in the Susquehanna numbers is the counter-argument to it.
The national environment points El-Sayed's way. The generic congressional ballot stood at D+6.6 and presidential approval at a net −21.7 on August 17, the last read the panel saw. The president's party has lost House seats in 18 of the last 20 midterms, and the two exceptions needed an impeachment backlash or a wartime rally that is nowhere in evidence. The same wind blows through every open seat this cycle, and on Iowa's open Senate race the same method still keeps Republican Ashley Hinson favored in spite of it.
Michigan decides these races by fractions. In 2024, running for the state's other Senate seat, Elissa Slotkin beat this same Mike Rogers by 19,006 votes, or 0.34 points, while Donald Trump carried the state by about a point and a half at the top of the same ballot. Nobody on either side of this disagreement is arguing for a comfortable margin.
Midterm polls in the Trump era have been nearly unbiased. Presidential-year surveys understated Republicans by three to five points, but the two midterms without Trump on the ballot missed by −0.3 in 2018 and +0.9 in 2022. There is no recent history of midterm polls underselling either party, so read these numbers close to face value.
The traditional handicappers still call it even. The models do not. Cook Political Report, Sabato's Crystal Ball and Inside Elections all rate the open seat a Toss-up, per PollingSource. Decision Desk HQ's forecast, which its August 22 write-up described as only narrowly leaning Democratic, gives El-Sayed 67% as of its September 18 update and lists the seat Lean Democratic, and The Economist, Silver Bulletin, Split Ticket and FiftyPlusOne have it Lean Democratic as well, per Wikipedia's ratings table.
Why The Panel Sits Eleven Points Below The Market
Every seat started from the same place: the midterm base rate and a deeply negative approval number put the Democrat ahead of even in a swing state. They split on how much weight the state polls deserve.
The high seat, Fable, sat at 60%, level with the market at the time of the run, and let the environment dominate:
A D+6.6 generic ballot with presidential approval at −22 tilts an evenly divided open seat Democratic, despite El-Sayed's measured underperformance versus Stevens and near-tied recent polling. — Claude Fable (84% on 508 graded calls at the August 20 run)
The seats at 52% read the head-to-heads as already containing the environment. Opus made that case most directly and held it after seeing the others push the national number:
The most direct evidence remains the live head-to-head feed: the non-partisan El-Sayed-vs-Rogers average sits at about Rogers +3, and the second aggregator has only just been dragged to a near-tie by a single new poll. That state-level polling already incorporates the national environment. — Claude Opus (85% on 578 graded calls at the August 20 run)
Every seat read the other four in the revision round and held its number. The blend landed at 54, six below the market's 60 at the time of the run and 11 below where it trades today, because the fuller polling record at the run still tilted Rogers and the exchange, reacting to the newest survey, had largely priced that tilt out.
The market's case is not careless. Democratic enthusiasm in a referendum midterm is exactly what a registered-voter sample misses, the generic ballot is the strongest single number on the board, and the campaign had barely begun at the stamp. The panel weighed all three and still would not chase El-Sayed to the market's price. It is not the only Midwest board where that happens: on Minnesota's open Senate seat, the models likewise shave points off a confident DFL price.
One caveat on the instrument: three of the usual eight seats were unavailable this run, so the blend is a five-model mean rather than the full panel.
What Would Move The Number
- Likely-voter polling into October. One strong poll is not a trend, and the screen matters: in the same August window, Beacon's Rogers +4 was registered voters and Susquehanna's El-Sayed +7 was likely voters. September brought the run: five straight likely-voter polls with El-Sayed ahead, every one by one to three points. A lead that grows past that band supports the market's price; a reversion to the Rogers-plus-three average makes today's 65-cent price the outlier.
- The first of the two scheduled debates, October 8. The two have never shared a debate stage. El-Sayed asked for five debates and Rogers agreed to two, October 8 on WOOD-TV and October 21 on WXYZ-TV, after skipping a Fox 2 Detroit town hall on September 15 over the moderator. One August poll, Susquehanna's, was enough to move this board four cents, and a debate moment is a bigger input than one poll.
- A traditional handicapper moving off Toss-up. The model-based forecasters already have. Cook, Sabato or Inside Elections shifting off Toss-up would be the first handicapper rating to follow the models.
- Third-quarter fundraising, reported in October. Through the July 15 filings, El-Sayed had out-raised Rogers for the cycle, $14.5 million to $10.9 million, but held the smaller cash reserve, $2.6 million to $4.5 million, after spending through a contested primary, per FEC filings. Whether El-Sayed refills that account is a real test of the consolidation thesis.
What The Panel Doesn't Score: The Controversies
The panel prices polls, environment and structure, not the day-to-day campaign. For the record, and framed strictly as the public record rather than judgment, both candidates have drawn scrutiny this cycle.
- Mike Rogers. Rogers has repeatedly claimed, without evidence, that his narrow 2024 loss and Michigan's 2024 election were tainted by fraud, claims Michigan officials and fact-checkers have rejected. He has faced carpetbagger questions over relocating to Florida after leaving Congress. PolitiFact rated as false his ad tying El-Sayed to a streamer's 2019 remarks about 9/11. His joint fundraising committee also lost $16,700 in April to a fake invoice sent from a hacked vendor email.
- Abdul El-Sayed. El-Sayed has faced criticism over resurfaced and since-deleted clips and posts of past progressive statements, and over a campus appearance with a streamer that Jewish groups and opponents criticized. He was also, per Al Jazeera, the target of an organized anti-Muslim messaging effort.
None of this enters the panel's number.
The Bottom Line
The market and the panel agree El-Sayed is the favorite and disagree only on how clear a one, 64 to 66 cents against 54. Only the result settles it. Until then the traditional handicappers still call it a toss-up, which is the safest reading of a state that settles its Senate races by fractions of a point. If this method is your thing, our North Carolina Senate board and our 2026 Senate election odds chamber breakdown are the natural next reads.
