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