Donalds's Odds Slid After a Two-Point Poll, Even as Republicans Took the Ballot Lead

The Florida governor market has spent the last week of the campaign moving toward David Jolly while the state's ballot count moved toward Byron Donalds's party. The best Republican price to win the governorship fell from 82% on Polymarket on October 23, 2026 to 71% on October 29, 2026, when Kalshi and Polymarket both quoted it, and Polymarket had the Democratic Party at 27% that day, three points under Kalshi's 30%. That 11-point fall in six days means the venues now treat Donalds as a clear favorite rather than the near-certainty they priced a week ago.

The sharpest leg of the slide came late on October 27, 2026, the date on a new St. Pete Polls survey for FloridaPolitics.com. Fielded October 25 to 27 among 916 likely voters, with a 3.2-point margin of error, it put Donalds at 47.8% and Jolly at 45.5%, a gap smaller than the poll's own margin of error. In the same days, the Florida Division of Elections' statewide count showed registered Republicans pulling ahead of registered Democrats in mail and early ballots cast, reversing the Democratic lead this site reported on October 23. The market has sided with the poll.

What the 71% price is saying

A 71% best price means the venues expect Donalds to win a little more than seven times in ten, against better than four in five a week earlier. The Democratic side tells the same story from the other end: Polymarket's 27% for Jolly's party on October 29, 2026, up from 19% there on October 23, means the venues now give the Democrats better than one chance in four. The two venues agree to the point on the Republican side, so the move is not one order book drifting away from the other.

The timing inside the week is specific. Kalshi had the Republican Party at 78% at 6:12 p.m. Eastern on October 27, 2026, already below the 83% it showed on October 23, and at 75% by 10:43 p.m. that night. By 5:35 p.m. on October 28, Kalshi was at 73% and Polymarket at 74%, and the two met at 71% by the afternoon of October 29. Most of the fall therefore came in the 24 hours after the poll was dated, though the slide had started before it.

The trading behind it is heavy. As of October 29, 2026, Kalshi had cleared about 6.41M contracts on the governor's race, about 780K of them in the previous 24 hours, and Polymarket had taken about $652K. A move made on that much activity is a repricing, not a thin book being pushed around.

Why: a two-point poll and an electorate split by when it votes

The St. Pete Polls survey is the clearest new evidence in the window. Its 2.3-point Donalds lead sits inside its own margin of error, and it found few voters left to persuade: 3.2% for someone else and 3.4% undecided or refusing. The poll weighted its sample to an active electorate of 42.8% Republicans and 30.7% Democrats, a heavier Republican share than the state's registration of 38.7% and 31.0% that the same document reports, so the narrow margin does not come from a sample tilted toward Democrats.

What sets this poll apart is how it splits by timing. Among the 46.0% of respondents who said they had already voted, Jolly led 57.8% to 38.4%. Among the 54.0% still planning to vote, Donalds led 56.7% to 34.4%. The poll is describing a race that Jolly is winning in the ballots already returned and Donalds is expected to win on the days still to come, with the total close enough that the remaining turnout decides it. A market priced at 82% had been assuming that second group was comfortably large enough. At 71%, it is less sure.

The poll's Senate question found a wider Republican lead. In the October 27, 2026 survey, Ashley Moody, the Republican the Senate's own roster lists as a sitting senator from Florida, had 49.0% against Angie Nixon's 44.7%, which matters for how differently the two markets have priced the week.

The ballot count points the other way

The Division of Elections' statewide statistics, compiled at 1:03 p.m. on October 29, 2026 and covering activity through October 28, show 1,567,049 mail and early ballots cast by registered Republicans and 1,515,753 by registered Democrats, a Republican lead of 51,296. Republicans lead the early in-person vote, 972,753 to 788,137, and Democrats lead the returned mail ballots, 727,616 to 594,296. Voters with no party affiliation have cast 717,560 ballots and minor-party voters 96,432, out of 3,896,794 in all.

The lead is new and growing. The Division's statewide files compiled October 28 at 2:02 p.m., covering activity through October 27, had Republicans ahead by 34,655. On October 23 Democrats led by 34,839, so the count has swung by more than 86,000 ballots in less than a week. In-person early voting did it: the Republican early-vote lead grew by more than 134,000 over those days, which more than offset a Democratic mail-ballot lead that also widened.

That is the pattern the market had expected all along, and the reason the price fell anyway is the size of it. The Division's archived final count for the 2022 general election shows Republicans ahead by 298,272 across 5,059,413 mail and early ballots. This year's Republican lead, with three days of mandatory early voting left, is a fraction of that, and the poll suggests that registration is not settling the vote: if Jolly leads among those who have already voted while registered Republicans have cast more ballots, then voters with no party affiliation, and possibly some registered Republicans, are voting for him. The price fell because the ballot lead is smaller than the market's earlier number assumed, not because Republicans are behind.

Mail ballots are still out. The same page shows 752,162 mail ballots sent and not yet returned: 298,633 to Democrats, 253,005 to Republicans and 178,652 to voters with no party affiliation. A voted mail ballot counts only if it reaches the county Supervisor of Elections by 7 p.m. local time on November 3, 2026.

The Senate market barely moved

The same week left the Senate race almost where it was. On October 29, 2026, Kalshi and Polymarket both had the Republican Party at 90% to win the Senate seat, down from 92% on October 23, and both had the Democratic Party at 11%. The St. Pete poll's Senate margin of 4.3 points was wider than its governor margin, and the market treats that difference as the difference between a race that has tightened and one that has not. As of October 29, 2026, Kalshi had cleared about 2.85M contracts on the Senate race, about 279K of them in the previous 24 hours, so the steadier price is not for lack of trading. The Florida Senate odds page carries that board.

The case against this read

The strongest case against the read is that the market has followed a poll over a count. A survey of 916 people with a 3.2-point margin of error is an estimate; the Division's figures are ballots. Republicans erased a 34,839-ballot deficit and built a 51,296-ballot lead in under a week, and the poll's own numbers say the voters still to come favor Donalds by more than 20 points. A reader who holds that view would say the price should have risen, not fallen, and that a Republican lead in hand with in-person voting still ahead is what a four-in-five favorite looks like.

That reader also has the timing. Kalshi's price was already down to 78% on the evening of October 27, before most of the movement, so the poll cannot account for the whole slide, and no single document explains the earlier part of it. The market's answer is that it is pricing the margin rather than the leader: a race decided by a few points on Election Day is a closer race than one decided by the 2022 pattern, and that is enough to take ten points off a favorite without making him an underdog.

What would change it

Catalysts: the Division of Elections' daily compiles through the end of mandatory early voting on October 31, 2026, any further public poll before Election Day, and election night itself. Polls close at 7 p.m. local time on November 3, 2026, and counties upload early-vote and tabulated mail results within 30 minutes of polls closing, so the count that decides the race comes in early that evening.

Invalidation: this read would be wrong if the Republican lead in mail and early ballots widens on each daily compile through October 31 and the Republican price climbs back to 80% on either venue before November 3, 2026; the market would then have sided with the count after all. If the price keeps falling while the ballot lead grows, the market is pricing the voters with no party affiliation as Jolly's, which is what the St. Pete survey implies.

The next dated beat is the Division's next compile on October 30, 2026, and the last day of mandatory early voting on October 31. The Florida governor odds page tracks the board between now and November 3, and the Elections Canvassing Commission certifies the official returns by 8 a.m. on November 17, 2026.
