On Texas Senate winner? (James Talarico), the best bid to buy YES is 64¢ and the best offer is 65¢, a spread of 1¢ around a 64.5¢ midpoint. The offer comes from the other side of the book: a NO bid at 35¢ is the same as selling YES at 65¢, because one YES and one NO always pay $1 together.
Bid: the highest price someone is willing to pay for YES right now. Offer (ask): the lowest price someone will sell YES for; on Kalshi it comes from the NO side, at $1 minus the best NO bid. Spread: the gap between the two, which you pay whenever you buy at the offer and later sell at the bid. Depth: how many contracts wait at each price; thin books move against a large order.
The price shown on market pages, here and elsewhere, is usually the midpoint between the bid and the offer, or the last trade. It is a probability estimate, not a price you are guaranteed to get.

On Texas Senate winner? (James Talarico), the best bid to buy YES is 64¢ and the best offer is 65¢, a spread of 1¢ around a 64.5¢ midpoint. The offer comes from the other side of the book: a NO bid at 35¢ is the same as selling YES at 65¢, because one YES and one NO always pay $1 together.
Every contract has a YES and a NO side that together pay $1, so a bid to buy NO at a price is the same as an offer to sell YES at $1 minus that price. Listing bids on both sides therefore shows the whole book.
On busy markets the best bid and offer are often a cent or two apart; thin markets can be several cents wide. The wider the spread, the more you pay to trade in and out, on top of the fee.
