Prize pool
Perfect bracket = 0 mistakes: every one of the 254 picks across both draws is right, Round of 128 through the finals. More than one perfect entry splits it.
Ties are split by call accuracy: if two entries finish level on total points, the one with more exact set-score points ranks higher, then handle A to Z.
Prizes are paid to the wallet on file. Eligibility is verified against Jupiter Prediction Markets activity on that wallet.

- Sun, Aug 30, 11:00 AM ETFirst ball: everything locks
Brackets and pre-draw picks freeze when play starts on Ashe. Withdrawals before then are re-synced into the draw, so check your bracket the morning of.
- Round of 16 onwardsMatch calls
Once the last 16 are set in a draw, call each match: winner, set score and whether it goes to a tiebreak. Each call locks at the scheduled start of its match, so a day's calls are made that morning.

Scoring
Everything adds to one combined leaderboard.
Your bracket · scored as results land
| Round of 128 winner64 matches | 1 |
| Round of 64 winner32 matches | 2 |
| Round of 32 winner16 matches | 4 |
| Round of 16 winner8 matches | 8 |
| Quarterfinal winner4 matches | 16 |
| Semifinal winner2 matches | 32 |
| Champion, wins the final1 match | 64 |
Points double every round, so each round is worth the same 64 in total and the max is 448 per draw, 896 for both. A pick that loses early simply stops scoring; there are no negative points.
Match calls · from the Round of 16
| Winner | 3 |
| Exact set scoree.g. 3-1, on top of the winner points | 5 |
| Tiebreak in the match, yes or no | 2 |
Multiplied by round: Round of 16 ×1, Quarterfinal ×2, Semifinal ×3, Final ×4. A perfect call is 10 points before the multiplier, up to 40 in the final. Men play best of five (3-0, 3-1, 3-2), women best of three (2-0, 2-1). If a player retires or gives a walkover, the winner still counts but the set score and tiebreak props are voided: no points, no penalty.
Pre-draw picks · per draw
| Champion | 25 |
| Finalist | 15 |
Finalist pays if your pick plays the final, either side.
Results
Scores come from the official US Open scoreboard and are graded automatically, usually within minutes of the handshake. Picks on a match that has already started are not accepted. If the draw changes before first ball (a withdrawal, a lucky loser), the bracket is re-synced and any pick on a player who is no longer in the draw is cleared; you will see it on your bracket. The organisers' decision on any dispute is final.
Fair play
One player, one entry.
- One entry per person. A single Discord account and a single wallet per player.
- No multiple or alt accounts, and no sybilling to enter more than once or inflate your odds.
- Entries we find linked to the same person (shared device, network, wallet funding, or duplicate picks) are set aside from the prize ranking and can be removed.
