15-minute rounds, opening soon
Chart: Hyperliquid mid price. Settlement uses the price signed on-chain at the round's end.
Same rules as the live series: Up or Down every 15 minutes, $1.00 per winning share, paid automatically.
Trade BTC nowPick Up or Down
Each round lasts 15 minutes. The strike is the HYPE price when the round opens. Up wins if the price at the end is at or above the strike (a tie is Up); otherwise Down wins.
Every share pays $1.00
Prices run from 1¢ to 99¢ and an Up and a Down share together are always worth $1.00 in USDC, so buying Down at 40¢ is the same trade as selling Up at 60¢. Both sides share one on-chain order book.
Winners are paid automatically
When the round ends, the round keeper posts the end price, settles the round and sends winning shares' USDC to their wallets. You never have to claim; a Claim button stays as a backup.
Fees
Makers (limit orders that rest on the book) pay nothing. Takers pay a fee of 7% × p × (1 − p) per share, at most 1.75¢ at 50¢ and close to zero near 1¢ or 99¢.
Market orders wait two blocks
A market order executes about 0.2 seconds after it lands, so makers can pull a stale quote first. It fills at your limit or better; anything unfilled goes back to your balance.
If no price arrives
If no end price is posted within 10 minutes after the round ends, the round is void and every share, Up or Down, pays $0.50.
