The 2026 season for the Superkarts! USA ProKart Challenge marks the 22nd edition of the organization’s flagship regional program. The championship is coming off a strong 2025 season that featured increased numbers from the last several years, enjoying a schedule that featured three premier facilities. This year’s championship format features the same three circuits in a five-weekend, six-round, one-drop structure to welcome drivers from all across the western half of the United States.

The 2026 Superkarts! USA ProKart Challenge is set to begin on April 24-26 at the popular K1 Circuit. The Winchester, California facility opened its doors to SKUSA competition for the first time at the end of 2024, welcoming huge numbers over the two weekends of racing. The ProKart Challenge program visited K1 Circuit three times in 2025 and will return for two visits in 2026. The opening event of the new season will feature a double-round format, with Round One being contested on Saturday and Round Two on Sunday. Pre-registration for the opening event of the 2026 SKUSA ProKart Challenge closes on Tuesday, April 21 at 11:59pm PDT before late registration and walk-up begins.

The 21st season of the ProKart Challenge concluded this past October, completing the five events with six rounds of competition for the Superkarts! USA regional program. Eleven different class champions were crowned following the action at the K1 Circuit finale event.

The 2025 ProKart Challenge was a best five of six championship format, visiting three facilities over five weekends. K1 Circuit hosted the opening two rounds in the first weekend of March before traveling to the new Spring Mountain Karting Complex in April for its debut on the PKC schedule. The series returned to K1 Circuit in June for Round Four before making a trip north to Sonoma Raceway in late August – for the first time in Superkarts! USA history since 2017. K1 Circuit hosted the series finale in October, helping to decide this year’s ProKart Challenge champions.

Keagan Kaminski was able to win for a second straight year in the Formula Works KA100 Senior championship. The 2024 title came without a victory, while Kaminski won five straight to clinch the 2025 crown prior to the series finale. The advantage was 187 points, with four-time podium finisher Jackson Menchu ending up second in the standings. Round Six winner Shea Aldrich completed the season third in the championship.

The 2025 season concluded for the ProKart Challenge following the action on October 11-12 at the K1 Circuit. The Winchester, California facility welcomed the Superkarts! USA regional program to close out its 21st season. A total of 161 entries battled around the 1.1-mile ‘Pro Track’ course for the sixth and final round of the 2025 championship.

The Formula Works KA100 Senior class featured a field of 41 drivers. Archer Eversman claimed his first top qualifier honor of the season, laying down a 1:03.510 lap. The session was so close, the top seven were within 72 thousandths, while the top 34 drivers were all within four tenths. Eversman led the first four laps of the Prefinal before Frankie Mossman took a turn – until Jake Drew advanced his way forward, taking the win. The 18-lap Final began with Drew leading the first lap before five-time race winner Keagan Kaminski worked his way up from qualifying outside the top 30 and into the lead by lap two. He led four laps before Drew returned back to the point. While Drew led, contact on lap 13 between Kaminski and Calvo took them out of the race, promoting Mossman and Shea Aldrich as the top challengers. Two laps later, Aldrich went from third to first. Leading the final two laps, Aldrich held on through the final corners to claim his first victory of the season. Jackson Menchu and Gavin McCune were able to slip by Mossman for second and third on the podium. Gerardo Peralta finished fifth for a best finish on the season.

The penultimate round of the 2025 ProKart Challenge took place at the Sonoma Raceway karting circuit over the August 23-24 weekend. It was the first time since 2017 that Superkarts! USA hosted an event at the Sonoma, California facility. The weekend weather was perfect for racing around the ‘National Pro’ layout, welcoming the second largest event of the season at over 160 entries competing in the 11 categories.

A total of 46 drivers contested the Formula Works KA100 Senior category on the weekend with the same end result as the first four rounds. Chase Hand was able to set fast time in qualifying, posting a 48.499 lap to edge out four-time race winner Keagan Kaminski by 75 thousandths. Hand was shuffled out of the lead on the opening lap of the Prefinal by Kaminski but returned to the point on lap three. He led until lap 10 with Texas Sprint Racing Series champion Jesus Vasquez Jr. taking control and the race win – as Jackson Menchu slipped into second. After leading the opening three laps of the Final, Vasquez dropped down to fifth as Hand took over the lead. Vasquez fought back to reclaim the top spot by lap 10. Hand led for a second time on lap 17, showing the way to the white flag. During the final circuit, Kaminski was able to work past Hand. Leading only the final lap, Kaminski celebrated his fifth straight victory on the season. Hand was short at the line by 58 thousandths, with Menchu joining them on the podium in third.
