Prediction Markets Miss On Another Trump Pick in Oklahoma

2026-6-17 18:52

Oklahoma added another wrinkle Tuesday to President Donald Trump’s governor endorsement record with prediction markets.

Heading into Tuesday’s Oklahoma primary election, prediction markets gave Trump’s pick, Mike Mazzei, a 90% chance to win. Instead, Mazzei finished second and is headed to an August runoff with Oklahoma Attorney General Gentner Drummond.

While Trump continues to see his congressional endorsees emerge victorious, Mazzei falling short Tuesday extends a rough run for Trump-backed gubernatorial candidates after similar disappointment in Georgia, Iowa and South Carolina.

State-level trouble

Trump’s state-level endorsements are underperforming right now, even when the prediction markets start from a very bullish position.

Mazzei went into Tuesday with roughly 90% odds in the markets, so the fact that he still fell short in the first round is a reminder that campaign politics can be a lot messier than the pricing suggests. Oklahoma is also now part of a broader pattern, not just a single upset.

The timing also matters because the runoff is still ahead. That keeps the race alive and gives Mazzei time to recover. But markets are tightening rather than staying steady. That already is enough to change the tone of the contest.

Markets are still with him

Even with the setback, Mazzei remains the market favorite for the runoff. The first-round result did not kill his path. But it exposed more risk than the market had been pricing in.

Mazzei had a market edge that proved less secure than expected. Now, traders are realizing the runoff will be more competitive.

Prediction markets are still on his side, but the trajectory is moving against the kind of certainty prediction markets like to imply.

South Carolina parallel

The South Carolina race makes the Oklahoma result more interesting. It suggests a similar pattern is forming across Republican governor contests.

In South Carolina, Lt. Gov. Pamela Evette had Trump’s backing and was an overwhelming favorite on prediction markets heading into the initial primary. While Evette finished first, it was not enough to clear the field and heads into a runoff next week. Since then, the losing candidates have backed her opponent, Attorney General Alan Wilson, who has since become the clear favorite on markets.

Oklahoma may not follow the exact same script, but it carries the same warning. Trump-backed governor picks are facing more resistance than the markets expected. Trump still matters a great deal, but state-level GOP governor contests are showing that his endorsement is not always enough to close the deal, especially when non-MAGA voters consolidate late.

Oklahoma tested the market’s confidence, but it was not fully shattered. Mazzei still looks like the runoff favorite, but the first-round result shows that the race is not as secure as the pre-election pricing implied. That makes Oklahoma another data point in the larger story of Trump’s mixed track record with gubernatorial candidates, where congressional endorsees have done better than state-level picks.
