$100,000 paper. One real pot.

How it works Live on mainnet — real $S&P500 at stake

How it works

Step 1

Get $100k paper

Every trader in a lobby starts with the same $100,000 of pretend money. No stock costs anything to "buy" — you're just allocating.

Step 2

Go long or short

Spread your $100k across any stocks on the board. Back the ones you think will move your way.

Step 3

Best return wins the pot

Portfolios lock at entry close. When the clock runs out, the oracles score everyone and the highest return takes the real $S&P500 pot.

A worked example

You put your $100,000 to work like this — then the market moves:

LONG $40,000 NVDANVDA +5%+$2,000
SHORT $30,000 TSLATSLA −3%+$900
LONG $30,000 SPYSPY +1%+$300
Your $100,000 becomes$103,200  (+3.2%)

Whoever's portfolio grows the most when time's up wins the whole pot.
