Starting bankroll: $10,000 in play money.
Every contract pays $1.00 if the outcome happens, $0.00 if it doesn't.
The leaderboard ranks by realized P&L, so you have to close a position for it to count.
Markets cover match result, total goals O/U 2.5, and both teams to score, plus futures.
Order book matching with price-time priority. Max 500 shares per order.
I won $180 trading recessions and gas prices on Kalshi and wanted to know what was
running underneath. How does the price move? Who is on the other side of my trade?
How does the platform know what to pay me? The way I learn is by building, so I built one.
Binary contracts
Each row in a market is a contract paying $1.00 if that outcome happens and $0.00 if it doesn't.
The price in cents is the implied probability. A contract at 40¢ means the market thinks there is roughly a 40% chance.
BUY YES if you think it happens. BUY NO if you think it doesn't. Buying YES at 40¢ is the same trade as selling NO at 60¢.
The order book
Post a limit order and it rests in the book until someone takes the other side. Prices come from traders, not from a bookmaker.
Price-time priority: the best price fills first, and at the same price the earliest order fills first.
Fills happen at the resting order's price, so if you bid 45¢ and the best ask is 41¢, you pay 41¢.
Your order can sweep several price levels. Whatever doesn't fill rests as a new limit.
Your money
Placing an order escrows your worst case loss up front: price per share to buy, 100 minus price per share to sell. You can never owe more than your bankroll.
Positions carry a weighted-average cost basis. Closing one realizes P&L against that basis.
The leaderboard ranks by realized P&L, so paper gains don't count until you close or the market settles.
Settlement
When a match ends, resting orders are cancelled and their escrow returned, then positions pay out at $1.00 or $0.00.
Settlement P&L stacks on top of anything you already realized by trading.
