Plan 26.75s
Establish a prior from the Trump-endorsement base rate in contested GOP primaries and Wyoming's history of independent primary outcomes, then update with the latest polling, fundraising, and prediction-market evidence; sq1/sq2/sq4 are mutually exclusive outcomes that must be normalized to sum to 1, with sq3 acting as a tilt factor toward whichever candidate the freshest credible signal favors.
Sub-questions (4)
sq1
Will Megan Degenfelder win the August 2026 Wyoming Republican gubernatorial primary?
She holds Trump's explicit endorsement, which historically is the single strongest predictor in deep-red-state GOP primaries, and is a statewide elected official.
w=0.40
sq2
Will Eric Barlow win the August 2026 Wyoming Republican gubernatorial primary?
The other co-favorite; his internal poll claims a large lead, and Wyoming has a history of legislative insiders and non-Trump-endorsed candidates (e.g., Gordon 2018) winning gubernatorial primaries.
w=0.35
sq3
Do the most recent credible (non-internal or independent) polls or prediction-market prices released after July 15, 2026 show Degenfelder leading Barlow?
Polling/market signal in the final weeks is the best available direct evidence; internal polls are typically biased 5-15 points toward their sponsor.
w=0.15
sq4
Will a candidate other than Degenfelder or Barlow (e.g., Brent Bien or another entrant) win the primary?
Determines the 'Other' bucket; multi-candidate plurality primaries in Wyoming have produced surprise winners, and Bien has run statewide before.

Evidence Synthesis 31.22s, 12 items
Trump endorsed Degenfelder and re-issued/doubled down on the endorsement on July 16, 2026, about a month before the primary.
Degenfelder also holds the endorsement of Wyoming's at-large U.S. Rep. Harriet Hageman and is running her campaign primarily on Trump's backing.
Barlow's campaign internal poll (n=400, MoE 4.9%) released July 21 showed Barlow 42%, Degenfelder 19%, Bien 14%.
No independent or non-campaign public polling of the Wyoming GOP gubernatorial primary was found; the only released poll is Barlow's internal.
Degenfelder's campaign manager publicly disputed Barlow's poll as self-produced; two of Barlow's three rivals also doubted the numbers.
In the 2026 cycle Trump-endorsed candidates won high-profile GOP primaries in Kentucky (Massie ousted), Texas (Paxton over Cornyn by 27 points), Indiana and Louisiana.
Trump's endorsement is not decisive everywhere: Rep. Randy Feenstra narrowly lost Iowa's June 2026 GOP gubernatorial primary despite Trump's backing.
Barlow is a 13-year legislator and former Wyoming House Speaker campaigning on protecting public lands, a salient state-specific issue.
The GOP field includes retired Marine Col. Brent Bien (running on a property-tax ballot initiative) and Curt Blake, creating a four-way race.
Barlow's internal poll placed Bien at 14%, well behind both leading candidates.
The Wyoming primary is scheduled for August 18, 2026, well before the question's September 10 fallback date.
A Monte Carlo prior combining Trump-endorsement base rates, polling uncertainty and third-candidate risk yielded roughly 0.59 Degenfelder / 0.35 Barlow / 0.06 other.
Information gaps
- No independent/public polling of the race; only a campaign internal poll
- No fundraising/cash-on-hand comparison between Degenfelder, Barlow and Bien
- Unclear which candidate the Wyoming GOP's July 24 endorsements favored
- No base rate for Trump-endorsed candidates specifically in Wyoming statewide primaries
Key uncertainties
- Accuracy of Barlow's internal poll vs. endorsement-driven name ID
- Whether Bien's property-tax base pulls votes from Degenfelder or Barlow
- Turnout composition in Wyoming's crossover-restricted primary
- Late Trump-aligned outside spending in the final weeks
Forecast 32.68s, opus, secondary
Rationale
(a) The question opened Aug 1, 2026 with the primary on Aug 18, 2026 — only ~2.5 weeks of campaign left, so little time for major shifts beyond late ad spending. (b) The status quo is a near toss-up between Degenfelder and Barlow, as Kalshi prices them, with Degenfelder holding the single strongest structural asset (a re-affirmed Trump endorsement plus Hageman's backing) in a state where Trump's word carried Hageman to a 66-29 rout in 2022; Barlow's counterweight is his internal poll showing a 42-19 lead, but campaign internals typically overstate by 5-15 points and it lacks independent corroboration. (c) A surprising but plausible outcome would be Brent Bien consolidating property-tax-focused conservatives into a plurality win in a four-way race, or a genuine Barlow blowout matching his internal — Trump endorsements are not universally decisive (Feenstra lost Iowa's June 2026 gubernatorial primary despite Trump). I weight Degenfelder marginally ahead on endorsement power, name ID from a statewide office, and likely outside spending, but stay close to the market's toss-up because Barlow's legislative network, public-lands message, and internal data are real signals. Bien polled 14% in a hostile internal and lacks obvious momentum, so 'Other' gets a modest but non-trivial share reflecting plurality-race volatility in a low-information, low-turnout primary.

## Question
Who will win the Republican primary for Wyoming's 2026 gubernatorial election?
## Description / Resolution Criteria
## Description
As of July 31, 2026, prediction markets such as [Kalshi](https://kalshi.com/markets/kxgovwynomr/gov-wy-nom-r/kxgovwynomr-26) have leading candidates Eric Barlow and Megan Degenfelder essentially as a toss-up. [Degenfelder](https://en.wikipedia.org/wiki/Megan_Degenfelder), Wyoming Superintendent of Public Instruction, has been [endorsed](https://cowboystatedaily.com/2026/07/16/degenfelder-releases-trump-double-down-endorsement-with-a-month-before-primary/) by Donald Trump. [Barlow](https://en.wikipedia.org/wiki/Eric_Barlow), a state senator, released an internal [poll](https://cowboystatedaily.com/2026/07/21/barlow-poll-claims-he-has-huge-lead-over-degenfelder-bien-in-gop-governor-primary/) showing a massive lead over Degendelder; polling has otherwise been sparse in the race. 
`{"format": "metac_reveal_and_close_in_period", "info": {"post_id": 45013, "question_id": 45166}}`
## Resolution Criteria
This question resolves as the winner of the Republican primary in the 2026 [Wyoming gubernatorial election](https://en.wikipedia.org/wiki/2026_Wyoming_gubernatorial_election#Republican_primary) according to [credible sources](https://www.metaculus.com/faq/#definitions).
## Fine Print
If neither named candidate wins before September 10, 2026, the question resolves as **Other**. 
***
This question's information (resolution criteria, fine print, background info, etc) is synced with an [original identical question](https://www.metaculus.com/questions/45013) which opened on 2026-08-01 15:00:00. This question will resolve based on the resolution criteria and fine print of the linked original question. However, if this question would resolve differently than the original question, then this question will be annulled. Additionally, if the original question's resolution could have been known before this question opened, then this question will be annulled.

## Required pre-forecast walkthrough
Before giving probabilities, address these explicitly in your rationale:
(a) The time left until the question resolves.
(b) The status quo outcome — the option most likely if nothing changes from today.
(c) An outcome that would be SURPRISING but plausible.
## Calibration guidance
- **Status quo anchoring.** Good forecasters put extra weight on the status quo option because the world changes slowly most of the time.
- **Leave moderate probability on most options.** Good forecasters don't drop options to ~0% — leave ≥3-5% on every option to account for unexpected outcomes, unless you have strong specific evidence ruling them out.
- Avoid uniform-distribution laziness — most options are not equally likely.
- **Anchor on prediction markets.** If liquid market prices (Polymarket / Kalshi) for these options appear in the evidence, treat them as a strong prior and stay close to them absent specific contrary evidence.
