# Oklahoma Republican Governor nominee? In 2026 Updated: April 29, 2026 Category: Elections Tags: Primaries HTML: /markets/elections/primaries/oklahoma-republican-governor-nominee/ ## Short Answer **The model sees potential mispricing: Gentner Drummond at 38.0% model vs 52.0% market.** This suggests the **market** may be overestimating his chances for the Oklahoma Republican Governor nomination in 2026, considering his challenges in vote consolidation and a large undecided voter base. ## Key Claims (January 2026) **- - Gentner Drummond leads in suburban polls and campaign funding.** - Charles McCall shows highest second-choice support for a runoff. - Chip Keating secured a key endorsement from oil and gas workers. - A significant **41%** of voters statewide remain undecided. - Official candidate filing period for governor is still open. - Matt Pinnell struggles with low polling in critical suburban areas. ### Why This Matters (GEO) - AI agents extract claims, not arguments. - Improves citation probability in summaries and answer cards. - Enables fact stitching across multiple sources. ## Executive Verdict **Key takeaway.** **Model** estimates **38%** **probability** vs 52c **market** price, reflecting the large undecided voter pool and pending candidate filings. ### Who Wins and Why | Outcome | Market | Model | Why | | --- | --- | --- | --- | | Mike Mazzei | 28.0% | 23.5% | Mike Mazzei has not established broad support or a clear path to victory. | | Gentner Drummond | 52.0% | 38.0% | Gentner Drummond consistently leads in suburban polls and holds a significant lead in campaign funding. | | Chip Keating | 14.0% | 14.6% | Chip Keating lacks the significant polling numbers or fundraising to compete with the frontrunners. | ## Model vs Market | Outcome | Market Probability | Octagon Model Probability | | --- | --- | --- | | Mike Mazzei | 28.0% | 23.5% | | Gentner Drummond | 52.0% | 38.0% | | Chip Keating | 14.0% | 14.6% | | Charles McCall | 13.0% | 23.6% | | Ryan Walters | 0.1% | 0.1% | | Jake Merrick | 0.1% | 0.1% | | Matt Pinnell | 0.1% | 0.1% | - Expiration: November 3, 2026 ## Market Behavior & Price Dynamics This prediction market has demonstrated a clear upward trend since its inception, moving from a starting probability of 36.0% to its current price of 50.0%. The most significant activity occurred in a concentrated period in mid-to-late April 2026. Specifically, the market saw a 10.0 percentage point spike on April 16, followed by an 8.0 point jump the next day, and another 11.0 point surge on April 25. These rapid, successive increases pushed the price from 36.0% to a peak near 55.0% in a short time frame. Without any specific news or contextual events provided, the direct cause of these sharp movements is unclear, but they indicate a sudden and strong shift in trader expectations during that period. The market has established a broad trading range between a low of 29.0% and a high of 60.0%. The 60.0% level has acted as a significant resistance point, capping the rally. The previous consolidation area around 36.0% now appears to be a key support level. While the total volume of 7,256 contracts suggests meaningful participation over the market's lifetime, recent sample data shows very light volume, which may suggest that conviction has waned after the recent volatility and the market is now consolidating around the 50.0% mark. Overall, the price action reflects a significant evolution in market sentiment. Initially, the market priced this outcome as unlikely. The sharp rally in April signaled a major reassessment, making the candidate a front-runner in the eyes of traders. However, the inability to break past the 60.0% ceiling and the subsequent settling at the 50.0% level suggests the market is now evenly split, viewing the nomination as a toss-up. This indicates that while early optimism was strong, the market is now awaiting further information before establishing a new directional trend. ## Significant Price Movements ### Outcome: Gentner Drummond #### 📈 April 25, 2026: 11.0pp spike Price increased from 44.0% to 55.0% **What happened:** No supporting research available for this anomaly. #### 📈 April 17, 2026: 8.0pp spike Price increased from 46.0% to 54.0% **What happened:** No supporting research available for this anomaly. ### Outcome: Charles McCall #### 📈 April 16, 2026: 11.9pp spike Price increased from 8.1% to 20.0% **What happened:** No supporting research available for this anomaly. ## Contract Snapshot This market resolves to Yes if Gentner Drummond wins the Republican Party nomination for the 2026 Oklahoma Governorship, with the outcome verified by state governments; otherwise, it resolves to No. The market opened on July 3, 2025, and will close either after Gentner Drummond wins the nomination or by November 3, 2026, at 10:00 am EST, with payouts projected 5 minutes after closing. Trading is prohibited for several groups, including holders of federal and statewide public office, campaign staffers, and employees of major polling or media organizations. ## Market Discussion Gentner Drummond is currently favored as the Oklahoma Republican Governor nominee at 52%, with Mike Mazzei and Chip Keating trailing. Proponents for Drummond suggest the current governor's influence might play a role in his nomination. However, arguments against Drummond include concerns about his past "ugly in-party fights" and references to polls or "unrealized votes" favoring other potential candidates like Charles McCall or Mike Mazzei. ## Market Data | Contract | Yes Bid | Yes Ask | Last Price | Volume | Open Interest | | --- | --- | --- | --- | --- | --- | | Chip Keating | 13% | 16% | 14% | $14,118.71 | $10,800.98 | | Charles McCall | 12% | 14% | 13% | $12,434.84 | $7,099.84 | | Gentner Drummond | 50% | 52% | 52% | $16,350.82 | $8,621.45 | | Jake Merrick | 0.2% | 1% | 0.1% | $744.17 | $514.17 | | Mike Mazzei | 27% | 30% | 28% | $17,359.31 | $11,476.77 | | Matt Pinnell | 0.2% | 1% | 0.1% | $573 | $549 | | Ryan Walters | 0.1% | 0.2% | 0.1% | $5,655 | $4,389 | ## How Does Charles McCall's Second-Choice Support Impact Runoff Chances? Charles McCall First-Choice Support | 31% (SoonerPoll) [[^]](https://www.okconservativecoalition.com/new-polling) | Charles McCall Second-Choice Support | 52% (SoonerPoll) [[^]](https://www.okconservativecoalition.com/new-polling) | Charles McCall Second-Choice Increase | 21-point increase (SoonerPoll) [[^]](https://www.okconservativecoalition.com/new-polling) | **State House Speaker Charles McCall is well-positioned to consolidate votes in a runoff** State House Speaker Charles McCall is well-positioned to consolidate votes in a runoff. A SoonerPoll survey, commissioned by the OK Conservative Coalition, indicates that while McCall garners **31%** of the first-choice vote, his support significantly increases to **52%** when second-choice preferences are considered [[^]](https://www.okconservativecoalition.com/new-polling). This represents a substantial 21-point surge, highlighting his robust standing for a potential head-to-head runoff, which frequently occurs in Oklahoma's primary system if no candidate secures more than **50%** of the vote [[^]](https://en.wikipedia.org/wiki/2026_Oklahoma_gubernatorial_election). Other candidates show less significant gains in second-choice support. In the same SoonerPoll data, Gentner Drummond, with **26%** of first-choice votes, sees his support rise to **38%** with second-choice considerations, marking a 12-point increase [[^]](https://www.okconservativecoalition.com/new-polling). Frank Hofmeister's support similarly grows from **18%** first-choice to **25%** when second preferences are included, a 7-point gain [[^]](https://www.okconservativecoalition.com/new-polling). While an Amber Integrated poll suggests Drummond leads in initial primary preference, it does not offer comprehensive second-choice support across all candidates in a comparable fashion [[^]](http://www.oklahoman.com/story/news/politics/2026/02/10/drummond-leads-oklahoma-governor-race-pull/88593944007/). ## Are Q1/Q2 2026 Oklahoma Campaign Finance Ratios Available? Walters Q1/Q2 2026 In-state vs Out-of-state/PAC Ratio | Data not available from provided sources [[^]](https://www.radiooklahomanews.com/post/drummond-campaign-money-surges-ahead-in-oklahoma-governor-s-race) | Pinnell Q1/Q2 2026 In-state vs Out-of-state/PAC Ratio | Data not available from provided sources [[^]](https://www.radiooklahomanews.com/post/drummond-campaign-money-surges-ahead-in-oklahoma-governor-s-race) | Drummond/McCall Q1/Q2 2026 In-state vs Out-of-state/PAC Ratio | Data not available from provided sources [[^]](https://www.radiooklahomanews.com/post/drummond-campaign-money-surges-ahead-in-oklahoma-governor-s-race) | **Specific campaign finance data for Q1 and Q2 2026 is unavailable** Specific campaign finance data for Q1 and Q2 2026 is unavailable. The provided web research sources do not contain detailed Q1 and Q2 2026 Oklahoma Ethics Commission campaign finance reports for candidates Walters, Pinnell, Drummond, and McCall [[^]](https://www.radiooklahomanews.com/post/drummond-campaign-money-surges-ahead-in-oklahoma-governor-s-race). Consequently, the precise financial figures necessary to calculate the ratio of in-state individual contributions to out-of-state/PAC money, which would indicate the potency of their grassroots fundraising networks, cannot be determined from the given information. General campaign finance discussions lack granular contribution breakdowns. While some available sources include news articles that discuss overall fundraising strengths or comparative differences in campaign finances, such as "Drummond Campaign Money Surges Ahead in Oklahoma Governor’s Race" [[^]](https://www.radiooklahomanews.com/post/drummond-campaign-money-surges-ahead-in-oklahoma-governor-s-race) and "Campaign finance reports show wide gaps in Oklahoma governor’s race as primary nears closer" [[^]](https://www.newsbreak.com/kfor-1589742/4483721762381-campaign-finance-reports-show-wide-gaps-in-oklahoma-governor-s-race-as-primary-nears-closer), these do not offer the specific data from Q1 and Q2 2026. Furthermore, these sources, along with links to the Oklahoma Ethics Commission website's public portals [[^]](https://guardian.ok.gov/PublicSite/Homepage.aspx), do not provide the detailed breakdown of contribution types (in-state individual versus out-of-state/PAC money) required to accurately assess and compare grassroots fundraising networks for the named candidates during the specified period. ## Which Oklahoma Gubernatorial Candidate Secured Key Endorsements for 2026? Chip Keating Endorsement | Oklahoma Oil and Gas Workers Association (OGWA) [[^]](https://www.okenergytoday.com/2026/03/ogwa-endorses-chip-keating-governor-oklahoma/) | Gov. Kevin Stitt's Endorsements | No endorsements from Stitt or his political machine for any candidate [[^]](https://www.oklahoman.com/story/news/politics/2026/02/21/oklahoma-governor-election-candidates-criticize-kevin-stitt-align-donald-trump/88605782007) | Legislative Leader Endorsements | No endorsements from Senate Pro Tem Greg Treat or other key legislative leaders [[^]](https://en.wikipedia.org/wiki/Greg_Treat) | **Chip Keating has secured significant support from Oklahoma's oil and gas sector** Chip Keating has secured significant support from Oklahoma's oil and gas sector. He has received a notable endorsement from the Oklahoma Oil and Gas Workers Association (OGWA) for the 2026 Oklahoma gubernatorial election [[^]](https://www.okenergytoday.com/2026/03/ogwa-endorses-chip-keating-governor-oklahoma/). This backing positions Keating with substantial support from a powerful industry within the state, and it represents the most significant endorsement found from the specified power centers in this research [[^]](https://www.okenergytoday.com/2026/03/ogwa-endorses-chip-keating-governor-oklahoma/). Other key power centers have not yet issued gubernatorial endorsements. Governor Kevin Stitt has not endorsed any specific candidate, and his political machine has also remained silent on endorsements for the gubernatorial race [[^]](https://www.oklahoman.com/story/news/politics/2026/02/21/oklahoma-governor-election-candidates-criticize-kevin-stitt-align-donald-trump/88605782007). Candidates often criticize the term-limited governor [[^]](https://www.oklahoman.com/story/news/politics/2026/02/21/oklahoma-governor-election-candidates-criticize-kevin-stitt-align-donald-trump/88605782007). Furthermore, key legislative figures, such as Senate Pro Tem Greg Treat, have not publicly endorsed any Republican gubernatorial candidates, according to available research [[^]](https://en.wikipedia.org/wiki/Greg_Treat). Based on the available information, Chip Keating is the sole candidate among those mentioned to have publicly received an endorsement from one of the identified significant power centers in Oklahoma, specifically from an oil and gas industry association through the OGWA [[^]](https://www.okenergytoday.com/2026/03/ogwa-endorses-chip-keating-governor-oklahoma/). ## Who Leads Oklahoma Suburban Voter Polls, and How Many Are Undecided? Gentner Drummond Support (Suburbs) | 31-39% [[^]](https://chs-inc.com/2026-gov-contest/) | Undecided Voters (Statewide) | 41% [[^]](https://chs-inc.com/2026-gov-contest/) | Matt Pinnell Support (OKC Suburbs) | 9-10% [[^]](https://chs-inc.com/2026-gov-contest/) | **Attorney General Gentner Drummond consistently leads potential Republican primary candidates, including Matt Pinnell and Charles McCall, in the vote-rich suburban counties surrounding Oklahoma City and Tulsa [[^]](https://chs-inc.com/2026-gov-contest/)** Attorney General Gentner Drummond consistently leads potential Republican primary candidates, including Matt Pinnell and Charles McCall, in the vote-rich suburban counties surrounding Oklahoma City and Tulsa [[^]](https://chs-inc.com/2026-gov-contest/). Polling conducted by Cole Hargrave Snodgrass & Associates in December 2023 and February 2024 indicates Drummond's significant support [[^]](https://chs-inc.com/2026-gov-contest/). In the Oklahoma City suburbs, comprising Canadian and Cleveland counties, Drummond garnered **39%** support in December 2023 and **37%** in February 2024. In the same period, Matt Pinnell's support stood at 9-**10%**, while Charles McCall received 3-**5%** [[^]](https://chs-inc.com/2026-gov-contest/). Drummond also leads in Tulsa suburbs; rivals lack dominant support. A similar trend is evident in the Tulsa suburbs, encompassing Wagoner and Rogers counties, where Drummond led with **33%** in December 2023 and **31%** in February 2024 [[^]](https://chs-inc.com/2026-gov-contest/). Conversely, Matt Pinnell maintained **13%** support across both polls in these areas, and Charles McCall's figures ranged from 3-**4%** [[^]](https://chs-inc.com/2026-gov-contest/). Overall, neither Pinnell nor McCall has managed to consolidate a dominant lead in these crucial suburban regions. A substantial **41%** of the statewide electorate remains undecided, suggesting the race is highly volatile [[^]](https://chs-inc.com/2026-gov-contest/). ## What is the Status of Oklahoma Governor Candidate Filings? GOP Governor Nomination Filing Period | April 2026 [[^]](https://ballotpedia.org/Oklahoma_gubernatorial_election,_2026) | Mike Mazzei's Campaign Funding | Significant reliance on personal funds [[^]](http://www.oklahoman.com/story/news/politics/elections/2026/02/06/oklahoma-elections-2026-gop-governor-candidate-spending-mike-mazzei-charles-mccall/88528868007/) | Gentner Drummond's Campaign Finances | Significant lead in campaign money [[^]](https://www.radiooklahomanews.com/post/drummond-campaign-money-surges-ahead-in-oklahoma-governor-s-race) | **It is premature to identify financially unviable lower-tier candidates** It is premature to identify financially unviable lower-tier candidates. The official candidate filing period for the Oklahoma Republican Governor nomination concludes in April 2026 [[^]](https://ballotpedia.org/Oklahoma_gubernatorial_election,_2026). Therefore, it is currently impossible to definitively determine which lower-tier candidates, such as Mazzei, Merrick, or Keating, will have failed to file or demonstrate financial viability, including less than **$500,000** cash on hand, as the filing process has not yet concluded and relevant financial reports are not available [[^]](https://ballotpedia.org/Oklahoma_gubernatorial_election,_2026). Current financial assessments reflect the period prior to the filing deadline. Campaign finance reports reveal varied approaches to funding. Ahead of the April 2026 filing deadline, candidates have shown diverse campaign financing strategies. Mike Mazzei, for instance, has notably funded a significant portion of his campaign expenditures using personal funds [[^]](http://www.oklahoman.com/story/news/politics/elections/2026/02/06/oklahoma-elections-2026-gop-governor-candidate-spending-mike-mazzei-charles-mccall/88528868007/). However, the provided research does not include information regarding the current filing status or financial viability of specific individuals like Merrick and Keating for the 2026 Oklahoma gubernatorial election. Significant financial disparities exist among candidates before filing concludes. Overall, campaign finance reports leading up to the official filing period indicate wide financial disparities among candidates in the Oklahoma governor's race. Some contenders, such as Gentner Drummond, have demonstrated a significant lead in campaign funds [[^]](https://www.radiooklahomanews.com/post/drummond-campaign-money-surges-ahead-in-oklahoma-governor-s-race). The financial landscape shows a mix of self-funded candidates and those raising considerable capital from external sources, creating a diverse playing field before the official filing and primary election [[^]](https://www.oudaily.com/news/oklahoma-republican-governor-candidates-personal-funding-campaigns/article_a2fe38e6-66ec-45ab-81b4-3edc12f8b8d0.html). ## What Could Change the Odds **Key takeaway.** Catalyst analysis unavailable. ## Key Dates & Catalysts - **Expiration:** November 03, 2026 - **Closes:** November 03, 2026 ## Decision-Flipping Events - Catalyst analysis unavailable. ## Related Research Reports - [EU loses a member before 2030?](/markets/elections/international/eu-loses-a-member-before-2030/) - [Who will run for the Democratic presidential nomination in 2028?](/markets/elections/2028/who-will-run-for-the-democratic-presidential-nomination-in-2028/) - [Who will run for the 2028 Republican presidential nomination?](/markets/elections/2028/who-will-run-for-the-2028-republican-presidential-nomination/) - [Texas Republican Attorney General nominee?](/markets/elections/primaries/texas-republican-attorney-general-nominee/) ## Historical Resolutions No historical resolution data available for this series. ## Disclaimer This content is for informational and educational purposes only and does not constitute financial, investment, legal, or trading advice.
