Contracts on Kalshi for Wilson rose 12 percentage points to 70% from a prior 58% by June 15, 2026. This shift appears driven by the consolidation of support from defeated primary rivals. **Key Market Signals** - **Nomination Repricing:** Kalshi contracts for Alan Wilson to win the SC GOP nomination increased to 70% from 58% (+12 pp) in the session ending June 15, 2026, directly repricing Pamela Evette's chances down 8 pp to 28%. - **Consensus Shift:** Market consensus has shifted, pricing in a belief that the over 55% of primary votes cast for defeated candidates will largely consolidate behind Wilson for the June 23 runoff. - **Catalyst Drivers:** The shift is primarily driven by endorsements from defeated primary rivals, such as U.S. Rep. Nancy Mace (12.1% of primary vote), and Evette's initial 28.9% primary vote ceiling, suggesting a large accessible voter pool for Wilson. --- In the week following South Carolina's June 9 Republican gubernatorial primary, prediction markets have significantly repriced the upcoming runoff, with odds shifting sharply in favor of Attorney General Alan Wilson. The move appears driven by a post-primary consolidation of support from former rivals, which traders are weighing more heavily than Lieutenant Governor Pamela Evette's first-place finish and a key endorsement from former President Donald Trump. Contracts on the Kalshi exchange for Alan Wilson to win the GOP nomination jumped 12 percentage points in the session ending June 15, 2026, rising to 70% from a prior 58%. In the two-candidate market, probability shifted directly from Evette, whose chances fell 8 percentage points to 28%. This repricing suggests traders believe the combined vote of the defeated primary candidates—who collectively won over 55% of the vote—will break decisively for Wilson in the one-on-one contest on June 23. ## Distribution Analysis | Outcome | Current Prob | Change | Volume | | :--- | :--- | :--- | :--- | | Alan Wilson | 70% | **+12.0pp** | 22,600 | | Pamela Evette | 28% | **-8.0pp** | 44,371 | **Net: Probability shifted decisively toward an Alan Wilson nomination, with his contract gaining 12 percentage points while his opponent's declined by 8 points on significant trading volume.** ## What's Driving the Shift The sharp repricing in favor of Wilson reflects the market's focus on the unique dynamics of a runoff election, where voter coalitions are reshuffled. * **Consolidation of Former Rivals:** A critical factor appears to be the endorsements from defeated primary opponents. U.S. Rep. Nancy Mace, who finished fifth with [12.1% of the vote](https://ballotpedia.org/South_Carolina_gubernatorial_election,_2026_(June_9_Republican_primary)), immediately endorsed Wilson on primary night, calling him a "law and order governor." The market move indicates a belief that supporters of Mace and other candidates are more likely to align with Wilson than with the Trump-endorsed Evette. * **Primary Vote Ceiling:** While Evette [finished first in the June 9 primary](https://www.nbcnews.com/politics/2026-election/south-carolina-governor-primary-runoff-pamela-evette-trump-rcna348699), she did so with just 28.9% of the vote. This left a vast majority of Republican primary voters—over 70%—who cast a ballot for another candidate. Traders appear to believe this creates a large, accessible pool of voters for Wilson, who finished a close second with 26.2%. * **Runoff Campaign Framing:** Post-primary messaging is also playing a role. Evette's campaign continues to lean heavily on her [endorsement from Donald Trump](https://www.postandcourier.com/politics/sc-governor-primary-election-candidate/article_552dfcc0-97a9-4840-bc56-8a746ede7114.html), which she credited as "rocket fuel" for her first-place finish. Meanwhile, Wilson's campaign has reportedly begun to [draw sharp contrasts](https://www.postandcourier.com/dupe-asset/sc-republican-primary-governor-spending-runoff/article_2efdbbeb-78f1-4a48-aebc-00201140a6aa.html), framing the race as a choice against a "finger in the wind politician." The market's shift suggests this strategy of coalescing the non-Evette vote is seen as more potent in a head-to-head matchup. ## Market Context The current market pricing of 70% for a Wilson nomination stands in stark contrast to the initial primary results, where he trailed Evette. This divergence highlights that traders are not simply extrapolating from the June 9 totals but are actively forecasting the outcome of a lower-turnout, more intense runoff election. The significant volume on the declining Evette contract (44,371 shares traded) compared to the rising Wilson contract (22,600 shares) suggests strong conviction among traders selling Evette's chances of holding her primary-night lead. In South Carolina, a candidate must secure [more than 50% of the vote](https://scdailygazette.com/2026/06/09/evette-wilson-head-to-runoff-in-sc-governors-race-johnson-clinches-democratic-nomination/) to avoid a runoff, a threshold neither candidate came close to reaching. ## What to Watch The primary catalyst for this market will be the runoff election itself on June 23, 2026. Before then, a televised debate scheduled for June 16 could provide the next major test for both candidates and potentially trigger further repricing. Both campaigns are also actively seeking the endorsement of third-place finisher U.S. Rep. Ralph Norman, whose support could be crucial in the final days of the race. The eventual Republican nominee will face Democratic nominee Jermaine Johnson in the [November 3 general election](https://ballotpedia.org/South_Carolina_gubernatorial_election,_2026_(June_9_Republican_primary)). ## Related Analysis - [Read the complete market report for South Carolina Republican Governor nominee?](/markets/elections/primaries/south-carolina-republican-governor-nominee/) ### Relevant Answer Library - [Are prediction markets accurate compared to polls or expert forecasts?](/answers/are-prediction-markets-accurate-compared-to-polls-or-expert-forecasts) - [Best prediction market tools in 2026](/answers/best-prediction-market-tools-in-2026) - [Can I hedge real-world risk using prediction markets?](/answers/can-i-hedge-real-world-risk-using-prediction-markets) - [Browse all Answer Library topics](/answer-library)
