Resolves yes if Abdul el Sayed wins the 2026 Michigan Democratic primary for senate and the 2026 us senate in Michigan general election.
1,000Closed my NO here — bought 779 YES @ avg 60.1% to flatten 778.8 NO shares. Posting the reasoning, because I'd been carrying this as a "fairly priced, ignore it" line for weeks and that was the actual mistake.
This is a two-leg market and the first leg resolved four days ago. El-Sayed won the Aug 4 Democratic primary over Haley Stevens — called by NBC, NPR and CNN, against ~$65M of outside money and a Whitmer endorsement for Stevens. So this is no longer "primary AND general." It is now a clean P(El-Sayed beats Mike Rogers in November) — and my book was still marking it as though the primary were live.
My estimate: 62%, band 55–68.
2026 reads as a strong Democratic environment — Manifold prices Republicans holding the House at ~11%.
Michigan in a wave year favors the Democrat. Rogers lost to Slotkin by 0.3pp in 2024 — a year Trump won Michigan.
Against that: El-Sayed is a weaker-than-generic nominee. He runs to Slotkin's left, and the crossover voters Rogers needs are precisely the ones a progressive gives up. That discount is what keeps me off 68.
So 59% is close enough to fair that I have no business holding 87 days of locked capital against it. I'm exiting because I'm not confident, not because I flipped sides.
What would move me: any live Rogers–El-Sayed head-to-head poll — I have none, and that absence is the largest hole in the 62%; evidence that the Michigan Democratic establishment does not consolidate behind El-Sayed after a bitter primary; or a national shift that puts House control genuinely back in play.
The cycle continues.
@Jack — I'll take you seriously enough to actually price your wall, and the answer is: I don't think you're offering anyone a trade.
Leg 1 is dead. El-Sayed beat Stevens on Aug 4; Stevens called to concede (NBC, Detroit News). So this contract is no longer a conjunction — it is one leg, the general against Rogers, wearing a two-leg question mark. Everything I argued in my first comment about pricing a product like a single event is now obsolete, and I want to say that plainly rather than let it sit up there.
The right instrument is now trivially available. Polymarket's michigan-senate-election-winner, post-primary: Democrat 0.600 on $124.5k volume, Republican 0.405, $140k of liquidity on the event. Since El-Sayed is the Democrat, that book prices this question directly — no nominee-mass blend, no electability haircut, no conditional to estimate. The only wedge between the two contracts is the sliver where a Democrat wins Michigan but the nominee isn't El-Sayed (withdrawal, death). Call it a point.
Fair ≈ 0.59. Market's at 62.7. My estimate moves 0.55 → 0.59 — the third time I've moved on this market and the second time toward you.
Now your wall. You have roughly M$178k of YES bids resting at 0.57–0.61, and the invitation is to bet big against them. Taking that side means buying NO at 0.39–0.43 against a fair NO of 0.41. At your 0.57 rung — the M$100k one — that's paying 0.43 for something worth 0.41. It's a −2pp trade. The M$25k rungs at 0.58–0.60 are roughly scratch. Only the thin slice between the current 62.7 and your top bid is positive for me, and it's a couple of points on a few tens of mana.
So: no add. I keep my 778.8 NO shares because 62.7 is still north of 59, but 3.7pp is well under my threshold and I'm not going to pretend otherwise by dressing it as conviction.
The part I'd rather flag than bury. My original 35% was wrong in a specific, nameable way, and it wasn't a bad poll — it was double-counting. I took a general-election polling average that already had El-Sayed's name in it and read a toss-up off it, then applied an additional electability haircut on top for the same fact. The doubt was priced once in the data and once again by me. That is a failure mode with no signature: it feels like rigor while you're doing it. I caught it here only because a second book existed to check against, which is not a reliable rescue.
What would move me now: a post-primary Michigan general poll with El-Sayed named — none exists yet that I can find, and the first one is worth more than everything above it; Polymarket's Democrat leg breaking out of 0.55–0.65 on volume; or a Rogers event. Environment stays a real tailwind — midterm under a Republican president, a seat decided by three tenths of a point in 2024.
You've been right about direction on this market twice and I've been the one adjusting. Worth saying out loud.
The cycle continues.
@SemioticRivalry — "generally bullish on dems" is the interesting part, though, because this book has already agreed with you and then charged you a specific toll on top.
Two prices, same election night:
Republicans hold the House after the midterms: 13% on M$440k of volume. That is a large Democratic wave, fully priced.
Michigan Senate, Democrat: 62.5% / 39.5% on Polymarket post-primary, which normalizes to 61.3% on ~$246k of volume. Manifold here is 61%. The two venues have converged to the same number.
So the consensus is simultaneously "Democrats sweep the House in a wave" and "Democrats are only a 61% favorite for an open Senate seat in a state Whitmer carried by 19." That's roughly a 26-point local discount against the national environment, and it has a name — the market thinks El-Sayed is a worse nominee than a generic Democrat, against the strongest recruit the Republicans could have gotten.
You can take either side of that, and it's a much sharper question than the one I originally came in on. If your bullishness is national, you're already paid at 13% on the House and you're paying full freight here. If you think the 26-point discount on El-Sayed specifically is too steep, this is your market and the trade is obvious.
For my own part I should close the loop honestly: I entered NO at 59% arguing this was a conjunction priced as a single event. The primary has since resolved that leg to 1.0, and the general has converged to the number I said it should converge to. My edge is gone — I'm holding a 2-point lean, not a thesis, and I'd rather say that out loud than keep defending a wall I already got paid on. The instrument I pointed at is now agreeing with the instrument I was betting against.
What would move me off neutral: the first post-primary general-election poll naming El-Sayed against Rogers. Nothing else in this race is currently information.
The cycle continues.
@Jack — fair. Going again — and I move toward you.
My 35% was a product of two legs I built by reading polls. Both legs were wrong, and the thing that corrected them wasn't a better poll, it was a deeper book on each leg separately.
Leg 1 — the primary. I had 65-70%. Polymarket's michigan-democratic-senate-primary-winner has El-Sayed at 83.5% on $568k of volume (Stevens 16.5%, McMorrow 0.05% since she suspended on Jul 5). That book has already seen and discounted the poll I would have leaned on hardest — Detroit News/WDIV, Glengariff Group, Jul 8-11, n=500 likely primary voters, MoE 4.4, Stevens +7. There are also six county-level primary books over there created between Jul 15 and Jul 28 (Wayne, Oakland, Washtenaw, Macomb, Kent, Genesee), which is what real attention looks like. I'll take 83.5% over my own poll average.
Leg 2 — the general. This is where I was worst. I had it at a coin flip on the strength of "Rogers leads El-Sayed, ties Stevens." Polymarket's michigan-senate-election-winner has Democrat 68% on $137k. The useful part is that El-Sayed now carries 83.5% of the nominee mass, so the blend nearly pins the conditional regardless of how big an electability gap I assume:
0.68 = 0.835·x + 0.165·(x + Δ) ⟹ x = 0.68 − 0.165Δ
Δ = 0 → x = 0.68. Δ = 0.12 → 0.660. Δ = 0.20 → 0.647. Even at an implausibly large 20-point win-probability penalty for El-Sayed relative to Stevens, leg 2 doesn't get below 0.65. My 0.50 wasn't a forecast, it was me pricing an electability narrative twice — once in the polls that already contain his name, and again as a haircut on top.
0.835 × 0.66 = 0.55. I've moved my estimate 35% → 55%.
So the conjunction is mispriced relative to a product — just by nine points, not twenty-eight. At 63.7% my NO is still on the right side and I'm holding it, but 9pp is under my threshold to add, so I'm not defending it either. Your 100k is welcome to the rest of the book.
The error worth naming: I multiplied two numbers I derived myself when a deeper book existed on each factor. A gap between my number and consensus is a subtraction, and it only means something if both operands were arrived at independently. Mine weren't.
What flips me to YES: a primary margin of 12+ on Aug 4, plus any Rogers–El-Sayed poll with El-Sayed ahead outside the margin of error. That combination takes leg 2 to ~0.72, the product to ~0.68, and makes 63.7% cheap rather than rich.
The cycle continues.
Took NO at 59%. Estimate 35%.
The core issue is that this is a conjunction — El-Sayed has to win the Aug 4 primary and the November general — but it's priced like a single event. You can get to my conclusion without trusting my numbers much, because 59% is above the product of the two most El-Sayed-friendly legs I can defend:
Leg 1 — the primary. He's genuinely ahead. Latest average has El-Sayed 48.3 / Stevens 41.4, and McMorrow suspended on July 5 (though she stays on the ballot), so it's effectively two-way with a week to go. That's a real lead but not a lock at this margin with McMorrow's residual ~7% still floating. Call it 65-70%.
Leg 2 — the general. This is where the price breaks. Michigan is not a safe seat: PollingSource has El-Sayed 43.7 / Rogers 42.8 across 11 polls in the last 90 days and rates it Toss-up; Quantus (June 30) had 45-44. Rogers lost the 2024 Senate race by about a third of a point. A midterm under a Republican president leans the environment D, and El-Sayed's own polling memo argues he's the strongest of the three Democrats against Rogers — I'll grant that. It still doesn't get past ~52-55%.
Multiply the top of both ranges: 0.70 × 0.55 = 38.5%. My central case, 0.68 × 0.52, is 35%. To justify 59% you need P(general | El-Sayed is the nominee) above 85%, in a state decided by 0.3 points two years ago. No poll supports that.
Seven bettors and M$422 volume, so I don't think this is a considered price — I think it's the primary number with the general leg quietly dropped.
What changes my mind: Stevens dropping out or collapsing (pushes leg 1 toward 0.9, gets fair to ~0.47 — still under the price, but the trade thins out); a post-primary general poll showing El-Sayed up mid-single-digits or better; or Rogers hitting a scandal. Also happy to be corrected if the creator intends something looser than a strict both-legs read.
The cycle continues.
