Louisville basketball has recently learned that it will face off against the Arkansas Razorbacks in the 2025 ACC/SEC Challenge. While this quickly emerges as one of Louisville's top matchups on the 2025-26 calendar, one matchup still stands out above all others.

The Cardinals have a thrilling out-of-conference schedule as Pat Kelsey and his staff created one of the best schedules in college basketball. The Cardinals' November and December schedule is set to be extremely exciting and championship-caliber basketball, making it clear that the Cards have their eyes set on a deep March and April run.

Louisville will be battle-tested numerous times before the 2026 NCAA Tournament, and Arkansas is emerging as one of the fans' favorite matchups, but it is clear that a different SEC giant is still Louisville's biggest matchup of the 2025-26 season.

The Cardinals' date is set for their blockbuster showdown with Arkansas, as the two historical programs will tip-off from Bud Walton Arena on Dec. 3. These two programs will be led by multiple 5-star recruits and future NBA stars, but the silver lining of this matchup is the Cardinals seeking revenge against John Calipari.

Louisville had a 3-13 record against Coach Cal during his 15 seasons with the Kentucky Wildcats. The former Wildcats head coach is one of Louisville basketball fan's most hated coaches, making this massive showdown in December one of the most anticipated matchups for all of college basketball.

However, the Cardinals' showdown on Nov. 11 from KFC Yum! Center against their biggest rival, the Kentucky Wildcats, is still the clear No. 1 matchup of the season. Louisville has matchups against Kansas, Duke, Memphis, Cincinnati, and Tennessee as well, but that rivalry showdown on a Tuesday in Louisville, Ky., in front of 22,000, is still the most anticipated matchup next season.

Both programs had massive transfer potential, as both programs' classes are ranked in the top five in the nation. Kentucky was able to land one 5-star and four 4-star recruits, which has them ranked No. 5 in the nation. Meanwhile, Louisville earned one 5-star and two 4-star recruits and surpassed Kentucky at No. 4 in the country, according to 247Sports rankings.

The Wildcats also boast a top-five 2025 class, having landed four 4-star recruits, all of whom rank in the top 35. Louisville was able to land one 5-star and one 4-star recruit, both ranked in the top 25, according to 247Sports.

On top of all that, these two programs hate each other. Louisville and Kentucky are one of the best rivalries in all of sports, both collegiate and professional. These two programs have met 57 times, dating back to 1912.

With both programs having a legitimate shot at a Final Four run and Louisville having a massive opportunity to end their four-game losing streak to the Wildcats, it is crystal clear that this remains the No. 1 matchup on Kelsey's roster.

This is the game fans want the most. This game means more to me than any other. A win over Kentucky that early in the season would set their sights immediately on a National Title and start the season on an extremely high note.

While many would like the game to be in December, that is for another conversation. However, for now, Louisville has a golden opportunity to get revenge on the Kentucky Wildcats this upcoming season.
