Mitch McConnell came back to the Senate on Monday, September 14, in a wheelchair, three months to the day after a fall at his Washington home put him in a hospital, then a rehabilitation center, then home physical therapy. He cast the deciding vote on a 47-46 cloture motion. His written statement that day admitted he is "still not quite back to 100%"; to reporters afterward he said it was "time to get back to work, finish the job for this Congress." Kalshi's contract on whether he resigns before Election Day had closed between 5 and 9 cents every day for a month, with a couple of brief intraday spikes into the teens. It opened the morning at 8 cents, sat in the 6s and 7s through midday, and was about 3 cents by the time the Capitol emptied out. This page's panel scored the same contract at about 6 percent (5.7, to be exact) in August, against a 12-cent market, and argued the price was answering the wrong question. Monday night we asked nine AI models to score it again without showing any of them the price, and the number they came back with is the reason the 3-cent question has a clean answer.

The Quick Answer
Kalshi's McConnell resignation contract traded at 3.3 cents bid, 4.0 cents ask late Monday night, down from 7.6 cents 24 hours earlier, which reads as a 3 to 4 percent chance that he resigns, retires early or announces he will before November 3, 2026. Our price-blind, nine-model panel re-scored the contract Monday night and blended to about 3.8 percent, with a median seat at 3. For the first time since we started scoring this market, the crowd and the models agree. The reason is the same one that made 12 cents wrong in August: the contract pays only on a voluntary early exit, and everything Monday put on the record, the vote, the wheelchair, the "finish the job" line, argues that McConnell intends to hold the seat until his term ends in January. What the return did to the price hour by hour, every seat's number, the one path to YES the panel refuses to zero out, and what would move this off 3 cents are all below.

What Monday Looked Like
The record of the day is short and it all points one way. McConnell's last recorded vote before the absence was June 11. On June 14 he fell at home, was briefly unconscious, and was hospitalized; a mild case of pneumonia followed. He spent roughly a month in the hospital and then weeks in a rehabilitation facility before being discharged on August 6 with a written statement that he would "maintain an intensive regimen of physical therapy from home during the state work period," per CNBC. By the time the Senate reconvened he had missed more than 60 roll-call votes, and as late as Sunday his office was still saying it had "no additional guidance or announcements."
Then Monday. He posted a statement saying he would cast his first vote "since I took a bad fall back in June," that his recovery "has been a long and often frustrating process," that "the lingering effects of childhood polio haven't made it any easier," and that he had assured Majority Leader John Thune he would "do my best to be present for tough votes when our Conference needs me." He entered the chamber in a wheelchair, NBC News and CBS News reported, and voted to advance Matthew Byrne's nomination to a federal district judgeship in Ohio. The official roll call shows the cloture motion agreed to 47-46. His vote was the margin. To reporters afterward, seated in the wheelchair, he said he was "here to work on the farm bill" and that he had "an ongoing interest in NATO," per Roll Call. Thune said he is "hopeful" he can count on McConnell for votes and that "as much as he can do, we welcome having him here."
The contract read the day in two steps. It opened the ET morning near 8 cents. In the 8 a.m. hour more than 11,000 contracts changed hands. The price dipped to 5 cents before settling in the 6s. It sat there all afternoon. Then, in the hour after 6 p.m. ET, with the vote recorded at 5:31 p.m. ET and his remarks to reporters on the wires, more than 20,000 contracts traded, the heaviest hour of the day, and the price went from the 6s to 4 cents. Sellers of YES outnumbered buyers in that hour by roughly seven to four. The next hour it printed as low as 2 cents before the bid settled in the 3s. Kalshi's records put turnover in the 24 hours through Monday night at about 99,600 contracts against 1.33 million contracts of open interest, so this was heavy, two-sided trading, not a thin-market wobble, even though the YES bid itself is small enough to move most of a cent on a few hundred contracts.
The Market At A Glance
The contract, the rule that decides it and the quote we scored against, all pulled Monday night:
| Venue | Kalshi |
| The Event | "Will Mitch McConnell resign his office early?" (Kalshi market KXRETIREMM-26), a single yes/no contract, "Before election day 2026" |
| Settlement Rule, Verbatim | "If Mitch McConnell has resigned, retired, or otherwise voluntarily stepped down from their Congressional office, or announced their intent to resign, retire, or otherwise voluntarily step down from their office prematurely, after Issuance and before Nov 3, 2026, then the market resolves to Yes." Early close: "This market will close and expire early if Mitch McConnell retires." |
| Deadline | November 3, 2026 (Election Day). Seven weeks from the return |
| Liquidity | Heavy turnover, thin top of book. About 3.36 million contracts traded over the market's life, about 1.33 million open, and about 99,600 traded in the 24 hours through Monday night; the three best YES bids at 10:06 p.m. held about 230 contracts combined (Kalshi's public data, September 14, 2026) |
| YES Quote, Monday 10:06 P.m. ET | 3.3¢ bid, 4.0¢ ask, last trade 4.0¢. 24 hours earlier: 7.6¢. The price the panel was scored against |
| Where It Was In August | About 12¢ on August 4, the day this page first scored it |

One thing changed on the contract itself since August, and it matters for the title of this page. When we first scored this market its rules carried a second sentence stating that "leaving office due to death will not resolve the market to Yes." Kalshi's rule text on file now no longer carries that sentence (the exchange's market record was last updated August 12), and it reaches the same place through two words: only a voluntary step-down, and only a premature one, pays. Death is not voluntary. Serving out the term to January 2027, the retirement McConnell announced on his 83rd birthday in February 2025, is not premature. Another hospital stay, another absence, another month of missed votes: none of it pays. The only thing that pays is McConnell himself deciding, and saying, that he is leaving early. That is the structure the August panel priced at 6 percent while the crowd was at 12, and it is the structure the crowd finally priced Monday night.
Every Seat's Number
Nine models scored the contract from a dated record of the return, the health timeline, the pressure on him and Kentucky's vacancy law, with no price anywhere in the prompt. Each then read the other eight rationales, anonymized, and could revise. Round two is the headline number.
| Model | Round 1 | Round 2 |
|---|---|---|
| Claude Fable | 3% | 3% |
| Claude Opus | 3% | 3% |
| Claude Sonnet | 4% | 4% |
| ChatGPT (GPT-5.5) | 4% | 4% (held; no round-two reply) |
| Gemini 3.1 Pro | 4% | 4% |
| Grok 4.5 | 7% | 7% |
| Kimi K3 | 3% | 3% |
| GLM 5.2 | 3% | 3% |
| DeepSeek V4 | 3% | 3% |
| Blend | 3.8% | 3.8% |
The blend is the mean of the nine round-two numbers; ChatGPT's round-one figure stands because that seat did not return a round-two reply, and the median seat is 3 percent either way. Nobody moved. Eight of nine explicitly held with a stated reason. The panel converged before it ever spoke, and the one outlier, Grok at 7 percent, held its ground too.

Where The Panel Landed
The anchoring fact in all nine rationales was not the fall. It was the vote. Claude Opus put the whole case in one sentence: McConnell "came back in a wheelchair, cast the deciding vote on a 47-46 cloture motion and said, 'Time to get back to work, finish the job for this Congress.'" A man who wanted out had all summer and a public demand from the governor to cite. He chose the wheelchair and the floor instead.
The rationales then separate his health from his intent, because the contract does. Claude Opus again:
"Much of that health risk turns into more absences, another hospital stay or death, and none of those pay YES." — Claude Opus
Claude Fable reached for the history:
"The base rate of a sitting senator resigning inside a specific seven-week window is well under 1%; even senators who died in office [...] overwhelmingly stayed absent rather than resign, and the settlement rule excludes death and absence." — Claude Fable
DeepSeek called Thad Cochran's 2018 exit "the closest health analogue," put the chance of a new health event over the window at 5 to 10 percent, and put the chance that such an event converts into a voluntary resignation, "given his demonstrated determination," at roughly 20 percent. Multiply those and you get 1 to 2 percent from that path alone; DeepSeek added thin slivers for political pressure and for a strategic early exit it called implausible under Kentucky law, and landed at 3, where five of the nine seats sit. ChatGPT laid out the same arithmetic in three pieces: about 2 percent on a new medical event producing an announced early exit, about 1 percent on family or staff pressure after more missed votes, about 1 percent on political pressure "becoming untenable."
Kentucky's law did the rest of the work. Under the state's 2024 law a Senate vacancy is filled only by special election and the seat sits empty until then, LINK nky explained in July, and the three-month threshold that would have let a special election ride along with November 3 passed on August 3, per Newsweek, though Beshear says the date does not bind his options and the provision has never been tested on a Senate seat. The August edition of this page listed a resignation timed to allow a concurrent special election as a thin third path to YES. That path is now closed on the arithmetic alone: the governor's proclamation has to reach county sheriffs at least 56 days before a special election, and 50 days remain before November 3. Either way the seat would sit empty until a special election. A resignation now leaves Kentucky with one senator and Republicans one vote lighter in a chamber where Monday's motion carried by one. Kimi's read: a resignation would hand the other party "an empty Kentucky seat," which is the exact opposite of what his party or his own words suggest he wants.
Then there is the pressure record, which the panel read and discounted. On July 28, Gov. Andy Beshear sent McConnell a letter asking him to "directly and verbally address the people of Kentucky and provide proof of your capacity to serve, or resign," NPR reported, and McConnell's office declined to comment. Over the weekend Beshear told Newsweek that "if he's not willing to do it, he should resign." No Republican senator, no party leader and no member of Kentucky's delegation has echoed him. The seats that weighed the letters discounted them on the same two grounds: the demand has no Republican backing, and it has produced no visible change in McConnell's own stated intent.
And the seat that would not come down. Grok stayed at 7 percent through both rounds:
"Fifty days is short, but not zero." — Grok 4.5
Its hold note says the residual "reflects a non-trivial frailty-driven voluntary-exit tail for an 84-year-old post-fall senator over 50 days." The rest of the panel does not disagree that the tail exists; it disagrees about how much of it converts. Claude Fable's hold note is the counter in one line: "another health setback would produce absence or death, both of which pay NO under this contract; only a voluntary announcement pays YES." Gemini described the YES case as relying "almost entirely on a rapid, catastrophic secondary health event where he survives but immediately concedes." That is a real scenario for an 84-year-old post-polio patient who is, in his own words, not back to 100 percent. It is also a narrow one, and it is the entire difference between 3 and 7.
Is 3 Cents Right?
That was the question the return raised, and the panel's answer is yes, with a small lean toward 4. The panel's 3.8 sits inside the 3.3-to-4.0 spread, so neither side of the book has an edge from the panel's number. In payout terms, a 4-cent YES contract turns $10 into $250 if McConnell announces an early exit before November 3 and nothing otherwise, before fees; a YES buyer is betting on one specific sequence, a health event he survives followed by his own announcement. The NO side pays 3.3 cents on 96.7 cents risked for 50 days, before fees, a return of about 3.4 percent that holds only if the frail-health tail stays as small as the panel thinks. The more useful part is how the market got here. In August it was 12 cents and the panel said 6. Through late August and early September it closed between 5 and 9 cents, closer to the panel than to its own summer price, while the record showed a discharge and a few signals of a return. Monday's return did not change the answer to the question the contract asks. It removed the doubt that had been holding the price above it.
What would move it, the three triggers the seats named:
- A Second Hospitalization Followed By Silence. Claude Opus's mover: "another hospitalization followed by his office and family going silent, or Thune changing his tone." Claude Fable's is the same event in fewer words: "a second hospitalization with his office going silent on return plans." A health event alone pays nothing; a health event that ends the "finish the job" framing is a different market.
- A Statement That His Doctors Have Told Him He Cannot Return. ChatGPT's mover: word "from his office or GOP leadership that doctors have advised he cannot return to Senate duties." That is the sentence that converts a tail into a resignation.
- A Republican Asking Him To Go. Gemini's version: a "new, permanent hospitalization causing Republican leadership to publicly urge him to step aside." Beshear's letters have had no visible effect on McConnell; the first Republican voice would, and Kentucky's empty-seat law is exactly why no Republican has raised one while his vote is the margin.
Until one of those lands there is no return date to worry about, because he has already returned. The price to re-run the arithmetic against is whatever the book shows when you look, not the 4 cents stamped on this page; the ask moved most of a cent in the six minutes between our two pulls. Everything here is analysis for information, not a recommendation to trade, and nothing here is a comment on what McConnell should do.

The Bottom Line
The August panel said the 12-cent price was too high by half, because the rule asks whether McConnell will choose to give up the seat, not how fragile his hold on it looks. The crowd got most of the way there by late August and the rest of the way Monday night, and nine models scoring the same record without the price landed within a cent of where it stopped. The thing to watch between now and November 3 is not the price. It is whether he keeps showing up for the votes Thune needs, because every scenario that pays YES starts with him being unable to. The settlement rule that excludes both the ending everyone fears and the retirement he already scheduled still does all the work, and read the same way it explains our LeBron James and Novak Djokovic retirement numbers too.
