How a yes-or-no question trades like any other market on the tape.
An order book is just a list of who wants to buy and who wants to sell, and at what price. On an event contract that list is small and readable: buyers of yes on one side, sellers on the other, and a spread between them. Learn to read it and you can see conviction, not just a headline number.
The best bid and the best offer bracket the market's opinion. A tight spread means the two sides broadly agree on the odds; a wide one means the question is still being argued out in prices.
Behind the top of the ladder sits the depth — the stacked size at each price. Heavy size on the buy side says demand is real; a thin market warns that a single order can move the last price.
Reading the tape is free; working a fill needs a sign-in. However you found your way here — a look at Kalshi betting, or straight for the Kalshi login — the same market opens. Sign in and take the side you have read.
