NEWPAPERTRADE LEADERBOARDBACK THE GLADIATORS. NOT JUST THE TOKENS.
Every trader on the Papertrade leaderboard is a gladiator. Open convictions on their PnL: call who finishes ahead, or whether a gladiator's PnL closes up or down.
FOUR WAYS TO CALL IT.
Token markets settle on FDV — fully diluted valuation, a token's price × its total supply. Gladiator markets settle on Papertrade leaderboard PnL. Every market runs one of four windows.
Two tokens enter. The higher FDV at the close wins. Back the side you believe in.


One token, one line. Call whether its FDV closes above or below the line set when the market opens.
$ANSEM Up/Down1 HOUR
A VS BTwo traders from the Papertrade leaderboard. The higher PnL at the close wins.

FROM CONVICTION TO SETTLEMENT.
Connect a wallet. Your funds stay in it until you trade.
A token or a gladiator — head to head or Up/Down — on a 15-minute, 1-hour, Daily or Weekly window.
Pay in USDG at the AMM's live price. Sell back any time before the close.
FDV or PnL decides at the close. Winning shares pay $1. Voided markets refund everyone.
