KalshiOhio's 5th District: Bob Latta Held the Seat the Market Had Priced as Settled
Bob Latta won Ohio's 5th District race. NBC News projected the Republican incumbent the winner over Democrat Brian Shaver and Libertarian Michael Veloff. With every Election Day precinct reporting, the Ohio Secretary of State's unofficial results, read at 9:52 a.m. Eastern on November 5, 2026, gave Latta 163,382 votes to Shaver's 128,142, a margin of 35,240, with Veloff at 9,577. The venues had priced that hold as all but certain: on November 2, 2026, Kalshi and Polymarket both had the Republican contract at 97% and the Democratic contract at 3%, which put a Shaver win at about one chance in thirty. On November 4, 2026 both venues quoted the Republican contract at 100%. The count is unofficial until the Secretary of State certifies it after the official canvass.
The Ohio 5th District race of 2026 put Republican Bob Latta, the sitting member, against Democrat Brian Shaver and Libertarian Michael Veloff, and the venues priced it as a Republican hold with very little doubt left in it. The market rests on the incumbent's standing in the seat and on a campaign-finance gap so wide that the challenger had almost no means to make his name known before November 3, 2026. That put the 5th among the Ohio seats where the statewide drift toward Democrats this fall did not register in the price at all. The live board above carries the final Kalshi and Polymarket prices.
The Candidates on the Ohio 5th District Ballot
Latta was the incumbent of record. The Clerk of the House member list, published October 1, 2026, shows Robert E. Latta, a Republican from Bowling Green, as the member for the 5th District; he also served in the previous Congress, and his current term started with his swearing-in on January 3, 2025, following the November 5, 2024 election.
Three names were certified for the November ballot. The Wood County Board of Elections candidate list for the November 3, 2026 general election, certified as of August 26, 2026, lists Brian A. Shaver for the Democrats, Bob Latta for the Republicans and Michael J. Veloff for the Libertarians under the 5th Congressional District. The same certified list also carries a separate 9th District contest, so Wood County voters did not all choose in the 5th: part of the county voted for the 5th District seat and part for the 9th, where Marcy Kaptur and Derek Merrin were the major-party nominees.
The federal campaign reports showed how uneven the contest was. In pre-general filings with the Federal Election Commission covering the cycle through October 14, 2026, Latta's committee reported about $1.77M raised, about $1.57M spent and about $799K in cash on hand. Shaver's committee reported about $59K raised, about $32K spent and about $39K in cash on hand. Veloff does not appear in the FEC's 2026 candidate list for the district. Party committees and outside groups report separately and are not counted in those totals.
Why the Ohio 5th District Price Sat So High
On November 2, 2026, Kalshi and Polymarket both had the Republican contract at 97% and both had the Democratic contract at 3%. Read on either venue, that priced a Shaver win at about one chance in thirty and a Latta hold as all but certain. The direction of travel matters as much as the level. On October 12, 2026 Polymarket had the Republican side at 93% and the Democratic side at 7%, so in three weeks the cheapest Democratic Yes lost more than half its value while statewide polling stayed close.
What the price is saying is that the market treats the 5th as insulated from the statewide contest. The statewide contest was close by every measure on file. Marist's poll of Ohio likely voters, in the field October 15 to 18, 2026, had Democrats ahead 49 to 47 on the generic congressional ballot, and the Suffolk University and USA TODAY Network Ohio poll released October 28, 2026 had Sherrod Brown ahead of Jon Husted 47 to 44 in the Senate race, and Survey 160's final poll, in the field October 27 to November 1, had Democrats ahead by five points on the generic House ballot. None of those polls reports results by congressional district, so none tells a reader how the 5th is leaning on its own. The venues filled that gap with the incumbent's record and the money.
The forecasters pointed the same way. Sabato's Crystal Ball, in its House ratings updated October 30, 2026, still left the 5th off the list of districts it rated as competitive, which left the seat at Safe for the incumbent party. A market near the ceiling and a forecaster that does not think the race worth listing are two different methods arriving at one answer.
Where the Ohio 5th District Money Went
The two venues told different stories about who was trading. By November 2, 2026, Kalshi had matched about 9,580 contracts on the district and Polymarket about $67.6K, each counted in its own unit. On Kalshi the trading was overwhelmingly on Shaver's side, about 7,840 contracts against about 1,740 on Latta's. On Polymarket the dollars ran the other way, about $43.8K on Latta's contract against about $23.8K on Shaver's.
The buying on the long shot did not stop before the vote. Kalshi recorded about 670 contracts in the 24 hours before the November 2, 2026 read and Polymarket about $365, and since October 29 more contracts have changed hands on Kalshi's Democratic side than on its Republican one, while that side's price on Kalshi fell from 4% to 3%. A run of buying on a long shot that does not lift its price usually means the buyers are meeting sellers who are content to keep offering the upset at a few cents, and the board's level after that run is a fair description of where the two sides met.
The Case Against the Ohio 5th District Read
The best argument against the market before the vote was that it was pricing a quiet seat in a year that was not staying quiet. Brown's lead in the Senate race and the Democrats' edge on the generic ballot both came from polls taken in the last two weeks of the campaign, Survey 160's among them, and a statewide shift of that size had to come from somewhere, including Republican-held districts no forecaster was watching. The Kalshi tape added a second strand: someone kept buying Shaver's contract in volume into the final days, and a holder of this view would read that as a trader who knew something about the district that the statewide numbers did not show. A third candidate on the ballot also changed the arithmetic of a close count, since a Libertarian vote can draw from either side. On that reading, a one-in-thirty price on a Democratic win was too short.
The answer the price gave was that none of those strands was evidence about the 5th itself. There was no public poll of the district, the Libertarian had no campaign on file with the FEC, and the Democratic challenger reported about $39K in cash on hand against the incumbent's $799K. The count kept the seat where the price had it, with Latta about 11.7 points ahead in the unofficial results. What the counterread still has is that a margin of that size is a clear win rather than a rout, and one held seat cannot show that a one-in-thirty price was the right size.
What Changes the Ohio 5th District Read
The read would be wrong now only if the official count reversed the unofficial one, and a margin of 35,240 votes leaves that a long way off. The dated, observable steps still ahead:
• Outstanding ballots: provisional ballots, and overseas and military ballots that arrive by mail within four days of Election Day, are counted in the official canvass; on November 5, 2026 the Secretary of State listed 98,369 provisional and 3,779 overseas and military ballots outstanding statewide, spread across all fifteen districts.
• The canvass: the Secretary of State says the official canvass is completed about three weeks after the election and that results are unofficial until it certifies them; no certification date is published on the results page.
• A recount: Ohio Revised Code 3515.011 orders an automatic recount in a district race only when the margin is under one-half of one percent of the total vote, and the unofficial margin here is about 11.7 points.
• Settlement: Polymarket resolves on a consensus of credible reporting about the winner's party; Kalshi pays on the party of the member sworn in for the term beginning in 2027, lists an expected expiration of January 4, 2027, and allows accelerated determination on a consensus media projection.
When the Ohio 5th District Market Resolves
Kalshi lists the race under its KXHOUSERACE-OH05-26 event. Its Republican contract resolves Yes if the House member sworn in for OH-05 for the term beginning in 2027 is a member of the Republican Party, and its Democratic contract on the same test for the Democratic Party; the listing gives an expected expiration of January 4, 2027, a latest expiration of November 3, 2027, and eligibility for accelerated determination once a consensus of media organizations projects the winner. Kalshi's House terms define that consensus as at least four of eight named news organizations calling the race, with none contradicting the call. Kalshi did not wait for the swearing-in: it settled both OH-05 contracts on that early clause at 10:32 p.m. Eastern on November 3, 2026, the Republican one at Yes. Polymarket resolves on the party of the candidate who wins the OH-05 seat in the November 3, 2026 election, as indicated by a consensus of credible reporting, falling back on the official results reported by the Federal Election Commission if there is ambiguity.
The Libertarian on the ballot is where the two rulebooks would part. Polymarket counts a winner with no Democratic or Republican ballot label as a member of whichever of those parties the winner last said they would caucus with. Kalshi's contracts are written on the party of the member actually sworn in, so a winner from neither party would leave both of its contracts short of Yes. With the market having priced a Latta hold near certainty, and Latta ahead in the count, that clause stayed a footnote, though it remains the one place the two venues could settle the same result differently.
