The Challenger Series is BULK’s weekly trading competition: trade → climb leagues → earn rewards → qualify for the Playoffs. Season 1 started on October 10, 2026 and runs for 8 weeks. Each week runs Saturday to Saturday.

​
Who can participate

All BULK traders with Trading AURA are automatically entered. No sign-up is needed. Market makers are excluded: accounts receiving tier 2+ maker rebates on any market during a week are not eligible for that week’s leagues, prize pool or Gauntlet rewards.

​
Leagues

Every week, active traders are ranked by Trading AURA and placed into a league: The league you finish the week in determines your rewards for that week. No spot is safe. Don’t get too comfortable.

​
Weekly prize pool

Each week, 12.5% of BULK’s net revenue (trading fees minus maker rebates) goes into the prize pool:
  • Challenger: 45%
  • Diamond: 25%
  • Platinum and Gold: 30%, shared so that each Platinum trader earns 2× what each Gold trader earns
Within each league, rewards are split pro-rata by Trading AURA. The minimum claimable reward is $5. Smaller rewards stay on your balance and add up until you reach it.

​
Weekly Gauntlets

Every week has one Gauntlet with 50,000 points (5% of the weekly AURA supply). All active traders are entered automatically. Gauntlet rewards and Trading AURA both come from the fixed weekly supply of 1,000,000 AURA. Nothing extra is minted. The current Gauntlet is announced every Saturday on The Challenger Series page. Rewards are pro-rata: your points = 50,000 × your contribution / total contribution of all participants. Example: if the Gauntlet counts taker volume, total taker volume for the week is 500Mandyoutraded500M and you traded 5M, you get 1%, or 500 points. Gauntlet rewards don’t count toward referral points.

​
Fair play

All rewards are subject to wash-trading and Sybil checks. Flagged accounts are excluded.

​
Playoffs

The top traders of the regular season qualify for the Playoffs, the final stage of the Challenger Series, with a separate prize pool. The regular season ends on December 5, 2026. The Playoff format will be announced closer to the date.
