Wyoming votes on Tuesday, August 18, 2026, and the state's only U.S. House seat is open for the first time since 2016: Representative Harriet Hageman gave it up to run for the Senate seat Cynthia Lummis is vacating. Nine Republicans are running to replace her, per the Wyoming Secretary of State's candidate roster dated August 11, in a heavily Republican state where the primary is likely to be decisive. Kalshi turned the field into yes-or-no contracts, and its board says this thing is mostly settled: Secretary of State Chuck Gray at about 66¢, everybody else fighting over the rest.
Here is the problem with that number. The most recent public poll of this race had Gray at 21%, and it was taken three months ago, with a third of Republican voters saying they had no idea who they were voting for. Wyoming has no primary runoff, so a plurality wins. A 66¢ favorite and a 21% plurality leader are two very different pictures of the same race, and the gap between them is where this whole race lives.
New to event contracts? Start with how Kalshi's yes/no markets actually work and the rest of this will read easily.
The Quick Answer
Kalshi's WY-AL Republican nominee market has Chuck Gray near 66¢ (64 bid / 68 ask) with Steve Friess second near 29¢ and nobody else quoted above 6¢, as of Sunday, August 16, 2026. The most recent public polling, a Fabrizio, Lee & Associates survey of 400 Wyoming Republicans fielded May 13-16, put Gray at 21%, Reid Rasner at 14%, Friess at 10% and 33% hard undecided. Since that poll: the Wyoming Republican Party formally endorsed Gray, combined campaign receipts passed $8.1 million with most of it the candidates' own money, and one candidate quit. The market is not disagreeing with the poll so much as it has stopped using it, and there is no newer public measurement to check it against.
- The Favorite: Chuck Gray, ~66¢, Wyoming's sitting Secretary of State and the state party's endorsed candidate
- The Challenger: Steve Friess, ~29¢, the race's biggest spender at roughly $2.49 million
- The March Leader Nobody Is Buying: Reid Rasner, first in a March poll and 14% in May, priced at ~2¢
- The Structural Fact That Matters Most: plurality wins, no runoff, nine active candidates plus a withdrawn name still printed on ballots
- The Trap: one contract on this board looks like it collapsed 47 points and did no such thing
Read two of these prices straight and they will fool you. I will show you both, along with what a 66¢ favorite in a nine-way plurality race actually has to be right about.

Why 66¢ Is A Very Big Number In A Nine-Way Race
Start with the structure, because in Wyoming the structure is doing more work than any campaign ad. Partisan primaries here are decided by plurality. Most votes wins. There is no runoff, no majority threshold, no ranked ballot. House Speaker Chip Neiman brought legislation in 2025 to create runoffs for Wyoming's top five elected offices and the bill died in the Senate after missing a deadline, so 2026 runs on the old rules.
That cuts both ways, and it is worth being precise about which way. A plurality rule lowers the bar for the favorite: Gray does not need 50%, he needs one more vote than whoever finishes second. But it also lowers the bar for everyone else, and in a nine-name field it makes the winning number small enough that ordinary polling error stops being noise and starts being the whole race. The reference point Wyoming keeps coming back to is 2018, when Mark Gordon won the Republican primary for governor with 33.4% against six opponents. A third of the vote was enough to run the state.
So when Kalshi prices Gray at 66¢, it is not pricing a candidate the polling shows running away with anything. It is pricing roughly a three-in-five chance, once you normalize the board, that one specific name clears a bar that might sit in the low 30s, in a nine-candidate field, with no second round to correct a surprise. Aggressive is the polite word for that. It requires the market to know something the last public measurement of Wyoming Republicans did not show.
The one thing to hold onto: in a plurality primary, the gaps between candidates and the polling error are the same size. Gray's 21% over Rasner's 14% was a 7-point lead in a survey carrying 4.9 points of error, with 33% of voters not picking anybody. A poll like that cannot reliably tell you who clears a bar as low as Gordon's 33.4%, which is why a 66¢ favorite here is a claim about turnout, not a claim about survey math.
What The Most Recent Public Poll Actually Said
There has been exactly one public poll of this primary since March, fielded May 13-16 and released June 1, and it now predates a large share of this campaign's spending. Fabrizio, Lee & Associates surveyed 400 Wyoming Republican voters May 13-16, 2026, with a 4.9-point margin of error. On the initial ballot test, as reported by Cowboy State Daily:
| Candidate | May 13-16 ballot test |
|---|---|
| Chuck Gray | 21% |
| Reid Rasner | 14% |
| Steve Friess | 10% |
| Jillian Balow | 8% |
| Bo Biteman | 7% |
| Kevin Christensen | 5% |
| Frank Chapman | 1% |
| David Giralt, John Romero-Martinez | <1% each |
| Hard Undecided | 33% |
The row that matters is the last one. A third of the electorate had not picked anybody, and the leader had 21%. Read that alongside Gordon's 33.4% and you get the honest shape of this race in May: the winning number and the undecided pile were roughly the same size.
The poll carries a partisan sponsor and a three-month gap, and both cut the same way. It is a partisan survey, and Cowboy State Daily reported that its "information" phase included disparaging comments about Friess and Rasner before re-asking the question, at which point Gray's support more than doubled to 48%. An informed-ballot number produced by a poll's own messaging is a measure of that messaging, not of the electorate. It is also three months, millions of dollars of campaign spending and one withdrawal out of date. Wyoming political figure Rob Wallace told Cowboy State Daily at the time that the real race would not start until after the Fourth of July. He was probably right, and nobody has published a number since.
It is also not the first poll to be overtaken. Peak Insights surveyed the race twice earlier in the cycle and had Rasner ahead of Gray, 24% to 21%, in late March. Rasner now trades at about 2¢. Whatever the market is using, it is not the polling.
The Market Is Trading The Endorsement, Not The Money
If you want to know where 66¢ came from, look at what happened after the poll rather than in it.
On Monday, July 20, the Wyoming Republican Party's central committee formally endorsed Gray, along with Hageman for Senate and Brent Bien for governor, breaking with the party's recent practice of staying out of contested primaries. The endorsement is contested in its own right: party leadership is running a federal challenge to the state law restricting pre-primary endorsements, arguing it violates the party's First Amendment rights. Whatever a court eventually says, the practical effect on August 18 is that the state party's formal backing sits with one candidate rather than being withheld from all of them. Add three-plus years of statewide name recognition from an office Gray already won statewide, and you can see the case a 66¢ price is making.
Note what that endorsement is not. Trump has stayed out of this race entirely, and in a Wyoming Republican primary his is the endorsement that usually settles the argument. He backed Hageman against Liz Cheney in 2022 and it was not close. So the market is not pricing the endorsement that historically decides these races; it is pricing the one that was available.
The money runs the other way, which is what makes this a real market rather than a coronation. Per FEC reports through July 29 compiled by Cowboy State Daily, Friess had spent about $2.49 million and still held roughly $797,000 in cash, Rasner had spent about $2.26 million and was down to about $79,000, and Gray had spent about $1.38 million with roughly $240,000 left. Combined receipts across the field passed $8.1 million, and the overwhelming majority of it is the candidates' own: an earlier July tally by WyoFile put self-funding at nearly 85% of the $7.13 million reported at that point. Friess, the son of the late conservative megadonor Foster Friess, helped raise the first $1 million for Tea Party Patriots and helped get Turning Point USA off the ground. He has funded this run with roughly $3 million in self-loans against about $469,000 in individual contributions.
Set those forces against each other and the board resolves into a single question. Gray has the party, the ballot-line familiarity and a proven statewide win. Friess has the largest checkbook and the biggest ad budget through the last reporting deadline. The market's answer, better than two-to-one for the endorsement over the checkbook, is a defensible read.
The Board, Priced
This is the full Kalshi board as of Sunday, August 16, 2026, showing the last trade alongside the live quote, because on the thin contracts those are different animals.
| Candidate | Last | Bid / Ask | 24h volume | Open interest |
|---|---|---|---|---|
| Chuck Gray | 66¢ | 64 / 68 | 5,940 | 21,507 |
| Steve Friess | 29¢ | 29 / 32 | 11,332 | 37,240 |
| Kevin Christensen | 4¢ | 5 / 6 | 803 | 2,845 |
| Bo Biteman | 4¢ | 1 / 4 | 28 | 401 |
| David Giralt | 3¢ | 0 / 1 | 0 | 456 |
| Reid Rasner | 2¢ | 1 / 4 | 292 | 2,500 |
| Frank Chapman | 1¢ | 0 / 1 | 0 | 925 |
| John Romero-Martinez | 1¢ | 0 / 1 | 0 | 60 |
| Jillian Balow | 1¢ | 0 / 1 | 0 | 386 |
The row I keep coming back to is the second one, and not for its price. Friess's contract traded 11,332 contracts in a day out of the board's 18,395, roughly 62% of all the activity, against 5,940 on Gray. That is where the argument is: not over whether Gray is the frontrunner, which almost nobody disputes, but over whether 29¢ is the right price for the chance he isn't.
Friess also carries more open interest than Gray, 37,240 against 21,507, which looks like more money backing the challenger. It isn't, and I nearly wrote that it was. Contracts are not dollars: 37,240 units at 29¢ is about $10.8K of notional against roughly $14.2K on Gray's smaller pile at 66¢, so cheap contracts simply buy more units per dollar. And open interest on a binary contract is two-sided by construction. Every open Friess position has somebody holding the NO against it, which means a big number there can just as easily be people betting he loses. Open interest tells you where the attention is. It never tells you which way the attention leans.
Two other rows are worth a sentence. Frank Chapman, the Moran rancher, withdrew on July 23 after absentee voting had already begun, and local reporting says early votes already cast for him will still be counted. And Jillian Balow, a former statewide officeholder as Superintendent of Public Instruction, sits at a penny with a 0-bid. The market is telling you that in this field, past statewide office without either the party endorsement or a seven-figure ad budget is worth approximately nothing.
One more thing worth knowing before you trust a board like this as a candidate list: it is not one. The Secretary of State's roster dated August 11 carries nine filed Republicans — Balow, Biteman, Christensen, Dodson, Friess, Giralt, Goodenough, Gray and Rasner. Kalshi also lists nine contracts, but they are not the same nine. The exchange still carries Chapman, who withdrew, and John Romero-Martinez, who is not on the state's roster, while offering no contract at all on Richard Dodson or Keith Goodenough. The two Kalshi-only names trade at a penny, and the two roster-only names have no contract at all, so none of it touches the Gray-Friess question. It is still a reminder that an exchange's board is a set of tradable propositions, not an official ballot, and the two are maintained by different people for different reasons.
Two Ways This Board Will Fool You
I promised you a trap, and there are two.
The first is Kevin Christensen. Pull up a screen that shows the previous price and Christensen looks like a catastrophe: a contract that was at 51¢ now printing 4¢, a 47-point collapse in a race nobody has voted in yet. It never happened. His live quote is 5 bid, 6 ask, on 803 contracts in the last day and 2,845 in open interest. That is thin, but it is not the thinnest: Bo Biteman prints at the same 4¢ on 401 open contracts and 28 traded all day. There is no 51¢ market to fall from. What you are looking at is a stale print on an illiquid contract, and the correct read of Christensen is not "collapsed" but "was never priced": a candidate running a grassroots campaign on about $36,000 who has told reporters that winning on that budget would itself be a national story. On thin contracts, always read the bid and the ask. The last trade is a rumor.
The gentler one applies to every row. Add up those last-trade prices and you get about 111¢, not 100. That excess is ordinary overround from quoting nine separate yes/no contracts, and it means each price on the board is running a little rich as a probability. Gray at 66¢ is a hair under a 60% implied chance once you normalize (66 divided by 111 is 59.5%), which is the same discipline as devigging a sportsbook price before you call it fair.
The habits that survive this race: on any thin contract, read the bid and the ask instead of the last trade, and on any multi-candidate board, normalize the column before converting a price into a probability. Both took ten seconds here and both changed the answer.
Worth noting: this is not a Kalshi quirk. A parallel market on the same race at Polymarket lands in the same place, Gray in the high 60s and Friess in the mid 20s. That is worth something, but less than it looks. It is about $55,000 of volume, and prices on identical contracts get arbitraged into line, so two books agreeing is not the same as two independent opinions agreeing. We are not linking or recommending either venue here, only comparing what they say.
How I'd Read The Gap
So which is right, the 66¢ or the 21%?
Neither, exactly, and that is the useful answer. The poll is a photograph of a race that had not started, taken by a partisan firm, in a field that has since lost a candidate and absorbed millions in advertising. The market is an informed guess by people reading the same news you can, weighted toward the endorsement and toward Gray's name recognition.
Stack the three numbers this article actually owns and the shape is clear enough. Normalize the board and Gray sits a hair under 60%. Gordon's benchmark says the winning number in a Wyoming plurality primary can be as low as the low 30s. And the last time anyone measured, the leader had 21%, the margin of error was 4.9 points, and a third of the electorate had not picked anybody. So the market is expressing roughly 60% confidence about which name clears a low bar, using no data collected since the field spent eight figures trying to move exactly that bar. Notice the coincidence I keep turning over: Gordon's winning 33.4% and this poll's 33% undecided are the same number. The pile of voters nobody had reached in May was, by itself, big enough to elect somebody.
The mechanism underneath all of it is turnout composition, and no public number measures it in advance. A party-endorsed statewide officeholder wins a low-turnout, high-loyalty primary comfortably. A self-funded outsider carrying a famous conservative-donor surname and the biggest ad budget in the state wins if the electorate skews toward casual voters who met these nine names on television in the last three weeks.
Since the turnout benchmark isn't public, grade me on the result instead, and do it Wednesday morning. If Gray clears 35% or wins by more than 10 points, the market read Wyoming correctly and 66¢ was cheap. If he lands under 30%, or wins by less than five, then the price was reading the endorsement rather than the electorate, and the poll's 33% undecided was the number that mattered all along. Either way I read 66¢ as more confident than the evidence behind it, which is a different claim from saying the favorite is wrong.
That habit is the transferable part. Ask what a price knows that you can verify, and when the answer is "nothing anyone has published in three months," treat the price as an opinion with a decimal point rather than a fact. It is the same discipline we run on games every day, and if you want to watch it applied to this week's slate, our free expert picks are the place to start.
In Summary
Wyoming spent this cycle building a race almost designed to embarrass a confident market: an open seat, nine active candidates, no runoff, a winning number that may start with a 3, an electorate a third of which was undecided at the last look, and a public polling record that stopped in mid-May. Into that, Kalshi has printed a favorite priced just under 60% once you normalize the board, and a second exchange agrees with it. On Tuesday the votes get counted and every one of these contracts settles, which is the part I like best about this format. Unlike a poll, a price has to be right out loud. We will know by Wednesday whether the market was reading Wyoming or just reading the endorsement.

Frequently Asked Questions
Does the winner of Wyoming's U.S. House primary need a majority? No. Wyoming decides partisan primaries by plurality, so whoever gets the most votes on August 18, 2026 is the Republican nominee even if that number starts with a 2. There is no runoff. Speaker Chip Neiman brought a bill in 2025 to create runoffs for Wyoming's top offices, and it died in the Senate after missing a deadline. The benchmark Wyoming keeps returning to is the 2018 Republican primary for governor, which Mark Gordon won with 33.4% of the vote against six opponents.
Why do the Wyoming House primary prices on Kalshi add up to more than 100 cents? Because you are reading last-trade prices across nine separate yes/no contracts that were each hit at a different moment. As of Sunday, August 16, 2026, the last trades on Kalshi's WY-AL Republican nominee board sum to about 111 cents rather than 100. That excess is the ordinary overround you see in any market quoted as separate contracts, and it means every individual price on the board is running slightly rich as a probability. Convert with that in mind before you treat 66 cents as exactly a 66% chance.
