The latest Monster Energy AMA Supercross main event was won by Jorge Prado in Seattle 2026 in the premier 450SX class.

Quick Scoop

If you’re asking “who won Supercross” about the most recent big race rather than the whole season, the answer right now points to the Seattle round of the 2026 Supercross series.

At that event, Jorge Prado (KTM) topped the 450SX field, with Eli Tomac and Cooper Webb close behind on the results sheet.

Latest headline result

  • Event: 2026 Seattle Supercross (450SX class).
  • Winner: Jorge Prado (KTM).
  • 2nd place: Eli Tomac.
  • 3rd place: Cooper Webb.

Because the Supercross season is ongoing, “who won Supercross” can mean the latest round winner (right now, Prado in Seattle) or the eventual season champion, which has not yet been decided for 2026.

If you meant something else

“Who won Supercross” could also refer to:

  • A specific round (for example, Glendale, Anaheim, Houston, etc.).
  • The overall season champion in the 450SX or 250SX classes in a given year.

If you tell me which round (city/date) or which season (for example, 2024 champion, 2025 champion), I can narrow it down to that specific winner.
