Who Wins the AL-01 Republican Primary?

Six weeks ago, Jerry Carl owned a 16-point lead in Alabama’s 1st District primary. Today that gap has shrunk to 8 points, and Rhett Marques is pulling in nearly every undecided voter who makes up their mind. The market has caught the shift. Marques now sits at 53.5 percent implied probability on May 19, a number that tells a story of momentum more than certainty.

The AL-01 Republican primary is one of the most competitive open-seat races in the South right now. Incumbent Barry Moore vacated the seat to run for U.S. Senate, leaving a seven-candidate field and a district that stretches from the Wiregrass region through Mobile and Baldwin counties. Winning the Republican primary here is tantamount to winning the general. The math doesn’t lie: whoever survives May 19 goes to Washington.

How the Rhett Marques Contract Works

A YES contract on Rhett Marques resolves at $1.00 if Marques wins the Republican primary for Alabama’s 1st Congressional District. The primary is scheduled for May 19, 2026. Any other candidate winning that primary resolves this contract NO.

• YES (Marques wins): $0.54, implying a 54% probability.
• NO (any other candidate wins): $0.47, implying a 47% probability.

Marques stays off the winning side if Jerry Carl, Joshua McKee, or any of the four other candidates on the ballot outpolls him on May 19. Carl is the strongest opposition. He represented this same district from 2021 to 2025 before losing a redistricting-driven primary to Barry Moore 52 to 48. Carl has the name recognition. Marques has the money and the trajectory.

Market Signals Show Deceleration, Not Conviction

Marques holds a 1h change of 0.0 percent, a 24h change of negative 1.0 percent, and a trend score of 8.85. That combination signals deceleration: the market drifted lower in the last day, but the elevated trend score indicates the move is stalling rather than accelerating. Here’s what the market is missing: a mild 24h pullback in a lightly traded contract often reflects position-taking around new polling, not a directional verdict.

Total volume stands at $39,208, with just $19 traded in the last 24 hours. Order book depth sits at $71,586. Thin daily volume at this level typically means low near-term catalyst pressure, but the depth suggests the market can absorb a news event without gapping wildly. Liquidity here is strong relative to the trading activity.

• Marques holds a 53.5 percent YES price reflecting a modest polling lead after closing the gap with Carl since January 2026.
• The 1h change of 0.0 percent and 24h change of negative 1.0 percent, combined with a trend score of 8.85, point to deceleration in selling pressure.
• Twenty-four-hour volume of $19 against $71,586 in order book depth signals a market waiting on new information before committing capital.
• The price has ranged from 0.63 to a low near zero since opening at 0.50, reflecting how dramatically sentiment has shifted over the contest.
• May 19 is 25 days out, and low volume periods typically precede sharp moves as primary day approaches and late-breaking developments surface.

Lines Analysis: Marques Leads but Carl Is Not Gone

Marques outraised every opponent in the final quarter of 2025. He ended that period with more than $775,000 cash on hand. Carl ended the same period with roughly $428,000 combined across his campaign account and joint committee. Marques is a sitting Alabama state representative from District 91, born and raised in Spanish Fort. He owns a local automotive service business. That biography plays well in a district that rewards outsider credibility alongside institutional ties.

Carl’s path back runs through name recognition and PAC support. He pulled $71,500 from PACs in the fourth quarter alone, including Alabama Farmers Federation and Blue Cross Blue Shield of Alabama. Carl closes this gap if late-breaking organizational support, a favorable endorsement, or a Marques stumble consolidates the field behind him before May 19. McKee and the four lower-profile candidates remain spoilers. A splintered field helps Marques; any consolidation around Carl reshuffles this market fast.

• Marques fundraising advantage: a sustained cash lead narrows Carl’s ability to run a late air war, pushing Marques odds higher.
• Carl endorsement from a major state figure: would signal party establishment swinging back, likely pulling the YES price toward 0.45.
• McKee or another candidate gaining momentum: splits the anti-Marques vote further, raising Marques to 0.60-plus.
• Runoff scenario: Alabama requires a majority to avoid a runoff; a crowded field increases runoff odds, extending the resolution timeline and compressing YES price short-term.
• Late polling releases: the Alabama Poll showed the gap halving in six weeks; a third survey showing Marques pulling ahead by double digits would push this market above 0.65.

The $39,208 in total volume reflects a market with genuine conviction that has been building since the April price jump. The data favors Marques, driven by fundraising dominance and a closing polling trend. Carl remains a credible threat, and the 47 percent NO price is not cheap insurance.

LINES VERDICT

Rhett Marques Favored in a Live Race

Marques leads on money, momentum, and the polling trend. Carl has the name recognition and the organizational base to keep this genuinely competitive through May 19.

What the market says: 53.5 percent probability for Marques, a slim majority that reflects a real contest, not a settled outcome. Expect price volatility to increase sharply as the May 19 resolution date approaches and any new polling or endorsement news hits the market.

Political Context

The Alabama Poll conducted in March 2026 showed Carl leading by 8 points, down from a 16-point advantage in January. Marques captured nearly every undecided voter who decided during that six-week window. The market price of 53.5 percent for Marques already implies the trajectory favors him even though a polling-based model might still show Carl narrowly ahead. That divergence is meaningful. Prediction markets often price momentum faster than traditional polls.

No major endorsements have been confirmed publicly as of April 24. The absence of a dominant state-level endorsement keeps the field competitive. Any announcement before May 19 from a high-profile Alabama Republican would be the single most significant catalyst this market has left.

Frequently Asked Questions

• What does 53.5 percent mean? Marques has a 53.5 percent implied probability of winning the May 19 primary, meaning the market currently judges him more likely to win than not, but far from certain.
• What does the NO contract pay? A NO contract pays $1.00 if any candidate other than Marques wins the Republican primary on May 19, 2026. Jerry Carl is the primary NO scenario.
• What moves this price? New polling, major endorsements, fundraising disclosures, and candidate news all shift trader positioning and drive the price up or down.
• When does this market resolve? The primary is May 19, 2026. The contract resolves once official results confirm the Republican primary winner.
• Is volume reliable here? Total volume of $39,208 with $71,586 in order book depth reflects a low-volume market. Prices can move sharply on small trades, so treat current probability as directional, not precise.
