Born in Atlanta, Georgia, Sloter attended Mount Pisgah Christian School, where he was a two-sport star.

[5][6][7] In his first season at Southern Miss, Sloter got red-shirted by the coaches in order for him to be able to compete for the starting job the next spring with a chance to be the Golden Eagles' 2013 starter as a redshirt freshman.

[11] As a sophomore, Sloter concentrated on developing his receiving skills but was buried down the depth chart, posting only 2 catches for 12 yards during the season.

[14] In his first year with the Bears, Sloter was initially used in a variety of position groups that included wide receiver and kickoff and punt return units until halfway through the regular season the team lost their backup quarterback, so Sloter was asked to move back to be the backup quarterback.

In the opening game of the season against Rocky Mountain College, Sloter ended up playing an entire half but threw only three passes, going 0-for-3 with an interception on his first attempt.

[16] The following week, the Bears faced Abilene Christian on the road when Knipp injured his shoulder in the first drive of the game.

[23] His 29 TD passes set a new UNC Division I single season program record and was named the Male Athlete of the Year.

[30] In the preseason, Sloter completed 31 of 43 passes for 413 yards with three touchdowns and no interceptions for a passer rating of 125.4, the highest of any rookie quarterback.

[36] On November 30, 2019, Sloter was signed by the Detroit Lions off the Cardinals practice squad following an injury to Jeff Driskel.

[47] On December 28, 2021, Sloter was signed to the Minnesota Vikings' active roster after backup quarterback Sean Mannion was placed on the Reserve/COVID-19 list.

[50] Sloter was selected in the 1st Round of the 2022 USFL draft by the New Orleans Breakers of the United States Football League.

[52][53] In Week 4, Kyle Sloter found Jonathan Adams for the game-winning touchdown with 0:10 seconds left against the Houston Gamblers.

[72] Sloter signed with the Birmingham Stallions of the USFL on April 20, 2023, and was subsequently transferred to the team's inactive list.
