The Race

Julia Letlow and Jamie Davis are heading to the general election on November 3 to fill Louisiana's U.S. Senate Seat (Class II). After competing in primary runoffs on June 27, Letlow dominated the Republican side with 56.9% of the vote, while Davis cruised to the Democratic nomination with 79.9%. The race pits the Republican establishment against a Democratic challenger in one of America's reddest states.

Ratings

Multiple election rating organizations (Cook Political Report, Sabato's Crystal Ball, and Inside Elections) all agree on one thing: this race is "Solid Republican" as of June 11.

Prediction Markets

Kalshi's prediction markets tell a remarkably similar story. As of June 29, bettors are giving Republicans a 91.89% probability of winning, with Democrats sitting at just 8.11%. That's nearly a 12-to-1 odds advantage for the red team. When you convert those to round numbers, Republicans are favored at roughly 92%, Democrats at 8%, which tracks almost perfectly with the expert consensus that this is a one-sided affair.

Experts vs. Markets

The Cook Political Report ratings and Kalshi Polymarket odds are pointing in the same direction with the same confidence level. That kind of alignment is rare in congressional race forecasts. It suggests the data is clean, the fundamentals are clear, and there's little uncertainty about the outcome.

With 21 total candidates on the general election ballot and outside spending already exceeding $15 million as of mid-June, this race has drawn serious money and attention. But the verdict, from both traditional analysts and real-money prediction markets, is already in: Republicans are heavy favorites to hold this seat.
