Boxing fight markets

Kalshi lists a YES contract for each boxer that pays $1 on a win. Fewer fights list than in MMA, and judges decide many of them, so reading the rules matters more here.

Method, not picks

How we approach Boxing

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. Judges are part of the price

    Many fights go the distance. We price how the scorecards could go, not only who looks better.

  2. Weight and late changes

    Missed weight and replacements happen. We re-check the plan after the weigh-in.

  3. Draws are real

    Read what a draw does to your contract before you buy. It's in the market rules.

  4. Same method

    Buy below fair value, place the sell order before the first bell, and write down the hold rule.

Before you trade

What to check first

  • Read what a draw or no contest does to your contract.
  • Re-check after the weigh-in.
  • Check the spread. Fewer traders can mean wider gaps.
  • Keep the stake to one unit.

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

The math on one plan

10 contracts, 22¢ buy, 35¢ sell order

Buy 10 YES at 22¢$2.20
Taker fee0.07 × 10 × 0.22 × 0.78 = $0.12012, rounded up$0.13
If the 35¢ sell order fills$3.50 back, minus a $0.04 maker fee if Kalshi charges one on that market (0.0175 × 10 × 0.35 × 0.65, rounded up)+$1.13
If it never trades and winsSettles at $1.00 × 10 = $10.00, minus the $2.33 cost+$7.67
If it never trades and losesSettles at $0. This is the most you can lose.−$2.33

Basics

How Boxing 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%. Your edge 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
