Tennis match markets

Each player gets a YES contract that pays $1 on a win. Prices swing set by set, which makes tennis a clean place to practice setting the sell target before the first serve.

Method, not picks

How we approach Tennis

What we look at before we write a plan. Every plan still has three lines: the buy price, the sell target and the hold rule.

  1. Read the retirement rule

    Players retire mid-match more often than in other sports. Check how the market settles if that happens before you buy.

  2. Surface and schedule

    Clay, grass and hard courts suit different players, and a long match the day before matters. Both go into our fair value.

  3. Momentum is not a signal

    A lost set moves the price a lot. The order we placed before the first serve does the work, not the feeling mid-match.

  4. Stale rows happen

    Kalshi's open list has carried past-dated matches. This board shows only markets whose close time is still ahead.

Before you trade

What to check first

  • A retirement does not pay the player who advances. It settles at the last fair price.
  • This is the opposite of a sportsbook, where a non-completion usually voids the bet.
  • Price retirement risk near 3% of matches, and lower on grass than on clay or hard.
  • A walkover before play begins also voids to the last fair price, not to your entry.
  • Check the surface split before trusting a ranking. Career gaps of 15 points are ordinary.
  • Downgrade underdogs at men's slams. Best-of-five suppresses upsets against best-of-three.
  • Expect the price to gap, not drift. A few points of edge is a landslide in set terms.
  • Sell into a player who finished after midnight and plays again inside 48 hours.

Every market on Kalshi has its own rules page. When our checklist and the rules disagree, the rules win.

Basics

How Tennis markets work

One contract

One YES per outcome

Each side gets its own YES contract. It pays $1.00 if that outcome happens and $0 if it doesn't.

Probability

Price reads as a chance

A 22¢ YES price means the market puts it near 22%. What matters is the gap between that and your own estimate.

Spread

Bid, ask and the gap

You buy at the ask and sell at the bid. The gap between them is a cost you pay every time you go in and out.

Fees

Fees move break-even

Kalshi's taker fee is 0.07 × contracts × price × (1 − price), rounded up to the cent. Resting orders on many markets pay a lower maker rate. Fee schedule
