Polls Show Alan Wilson Losing Ground in SC Governor Race — So Why Are Markets Buying Him Up?

South Carolina Attorney General Alan Wilson held early frontrunner status in the Republican gubernatorial primary for months. That status is now in question. Lieutenant Governor Pamela Evette leads Wilson in two of the three most recent polls of likely GOP primary voters, and the third survey, conducted in mid-April, already showed Wilson's support ceiling at just 20% with 28% of respondents undecided.

Yet prediction markets are moving in the opposite direction. Wilson's implied probability of winning the June 9 Republican nomination has climbed from 28% to 37% over the past three days, a 9-percentage-point surge. His price on Kalshi sits at 40%, Polymarket at 32%, and PredictIt at 39%. The period low was 27%, meaning Wilson has gained 10 percentage points from his floor. Either the market is pricing in structural advantages that surveys cannot capture, or a correction is coming.

The divergence is not subtle. It is the defining tension of this race with 17 days until the primary.

Pamela Evette Leads the Latest SC Republican Governor Polls — Here's What the Surveys Show

The most recent Trafalgar Group poll, conducted May 2–5 among 1,089 likely Republican primary voters, puts Evette at 25.2% and Wilson at 23.1%, a gap of 2.1 points. Ralph Norman sits at 19.6%, Nancy Mace at 15.2%, Rom Reddy at 10.1%, Josh Kimbrell at 4.2%, and Jacqueline Dubose at 2.7%, according to FOX Carolina.

A co/efficient poll released May 8, surveying 813 likely voters, confirmed the trend: Evette 21%, Wilson 18%, Norman 13%, Mace 12%, Reddy 11%, Kimbrell 2%, with 29% undecided, per 270toWin. Wilson trailed Evette by three points in that sample.

Only the older Starboard Communications poll from April 8–14, with a smaller sample of 604 likely voters, showed Wilson leading the field at 20%. Even there, Evette was already at 12% and climbing, as FOX Carolina reported. The trajectory is clear: Wilson's polling share has eroded from a modest lead to a deficit across the spring.

Alan Wilson's Prediction Market Odds in the SC GOP Governor Race: Live Tracker

Despite the polling deterioration, Wilson's market price tells a different story.

At 37%, Wilson is priced as the most likely nominee across the three major platforms tracking this race. The 8-percentage-point spread between Kalshi (40%) and Polymarket (32%) suggests disagreement among trader populations, but all three platforms agree on the directional bet: Wilson is gaining, not fading. The cross-platform consensus reinforces that this is not a single-platform anomaly or a liquidity-driven spike.

For context, a 37% implied probability in a multi-candidate field is not a commanding position. It means the market believes Wilson loses roughly six times out of ten. But it also means the market views him as the single strongest candidate, ahead of Evette and the rest of the field, even as polls say otherwise.

What's Driving Alan Wilson's Market Surge? The News Behind the Numbers

Prediction markets don't move 9 percentage points in 72 hours on vibes. The most plausible catalyst is Wilson's ground-game activity, which has been visible and aggressive.

On May 11, Wilson's campaign announced endorsements from Upstate leaders including Pickens County Councilman Chris Bowers, Easley City Councilwoman April Searcy, Greenville County Councilman Frank Farmer, and Greenville County Clerk of Court Jay Gresham. The Upstate is the state's most reliably conservative region and the territory where Republican primaries are often decided by turnout margins.

Wilson also launched his first statewide television ad, "Convoy," in mid-April, highlighting his military service during Operation Iraqi Freedom II. That ad has been running for roughly four weeks. Market participants may be weighting the institutional advantages of a four-term attorney general with a statewide voter file and established donor base over the snapshot of a horse-race poll.

Wilson's own framing reinforces this theory. "People are being squeezed by rising costs, growing government, and policies that make it harder to get ahead," he said in the endorsement announcement, positioning himself as the economic-anxiety candidate in a field where Evette carries the incumbency association of the current administration.

The Case Against Wilson: Why the Market Could Be Wrong

The strongest counterargument is simple arithmetic. In a crowded field heading toward a potential runoff, Evette's polling lead may matter more than Wilson's institutional advantages. South Carolina requires a majority to win the primary outright; if no candidate clears 50%, the top two advance to a runoff on June 23.

Evette's trajectory is the problem for Wilson bulls. She climbed from 12% in the April Starboard poll to 25.2% in the May Trafalgar survey, more than doubling her support in under a month. Wilson moved from 20% to 23.1% over the same period. The momentum gap is not close. If undecided voters continue breaking disproportionately toward Evette, as the last two surveys suggest, Wilson could enter a runoff as the underdog with less room to consolidate anti-Evette support than the market currently implies.

There is also the question of whether Norman (19.6% in the Trafalgar poll) and Mace (15.2%) draw more from Wilson's lane or Evette's. If they draw from Wilson's coalition of conservative-movement voters, his path to a plurality narrows further.

Price History and What Happens Next

The chart above captures the 9-percentage-point climb. The market resolves on June 9, giving traders 17 days to reconcile this divergence. New polling will be the most likely catalyst in either direction. If a late-May survey confirms Evette's lead and shows it widening, expect Wilson's price to correct. If internal polls or endorsement cascades break Wilson's way, the market's current bet will look prescient.

The most honest read of the data right now: the market is making a contrarian bet that Wilson's institutional depth, Upstate ground game, and statewide name recognition as attorney general will outperform his topline polling numbers. That bet is defensible but not comfortable. At 37%, the market is not pricing in confidence. It is pricing in hope that the candidate who built the best machine will outrun the candidate with the best recent numbers. The next two weeks will determine which signal was real.
