One question.
Two possible outcomes.

The general fee is 7% of the contract count multiplied by the price and by one minus the price, rounded up per order — which means it peaks at contracts priced near 50c and shrinks toward either end. That shape matters: the fee on a coin-flip market is a far larger share of the edge than on a market priced at 90c. Market-specific fees and partial fills can differ from the general formula, and the explorer applies it at entry so a quoted price is never mistaken for the cost.

Because you are reading two asking prices, not one probability. The Yes ask and the No ask each include the spread the market is charging to trade with you, so buying both sides at the ask costs more than the $1 the pair can ever pay out. The gap between them is the cost of immediacy, and a wide gap is a signal in itself — it means a quoted price is a rough read rather than a firm one.

At settlement the correct side pays $1 per contract and the other pays nothing. There are no partial outcomes: a contract bought at 62c either returns $1 or returns zero, so the gain and the loss are fixed the moment you enter. Selling before settlement is a different question entirely, because it depends on someone being willing to buy at that moment — time alone does not move the price to where you want it.

No. This reads Kalshi's public market data and works out what a position would cost and pay. It holds no money, places no orders and connects to no brokerage or exchange account. Every payoff figure is a scenario built from current quotes, and the exit prices shown are hypothetical rather than bids available to you right now.
