What do YES and NO prices mean in a prediction market?

Short answer

A price of 62 means a share costs $0.62 and pays $1.00 if you are right, so the market puts the chance near 62%. A price is only worth taking if you have a good reason to think the real chance is clearly higher, after costs.

01

Price in cents = cost per share = the market’s rough odds.

02

Shares = amount ÷ price. Profit if right = shares × ($1.00 − price).

03

A market price is an estimate, not a guarantee; liquidity and fees shape it too.

Price, cost and odds

Prices are shown from 0 to 100, which you read as cents per share. A price of 25 means a share costs $0.25; a price of 80 means $0.80. Because a winning share pays $1.00, the price is also the market’s rough estimate of the chance: the closer to 100, the more likely the market thinks the outcome is.

YES and NO on the same market sit on opposite sides. With YES at 62¢, NO trades near 38¢. Read a price as an estimate, not a fact. It also reflects liquidity, spreads, fees and how people behave around uncertain news.

The NO side works the same way from the other direction. Buy NO at 38¢ and you pay $0.38 per share, which pays $1.00 if the event does not happen. Your profit if right is 62¢ per share, and your loss if wrong is the 38¢ you paid.

A YES price is the market’s probability

Counting shares and payoff

Shares = amount ÷ price. Say you put $60 into YES at 62¢. You get 96 shares (rounded down). If the market resolves YES, they pay $96, a profit of $36 before the opening fee. If it resolves NO, you lose the $60.

62¢96 shares$96$36
40¢150 shares$150$90
25¢240 shares$240$180

Cheaper contracts pay more when they win, because the market thinks they win less often. That is the trade-off, not a bargain.

Moves before the result

An open position is valued at the current price. If you hold 4,000 YES shares bought at 25¢ ($1,000) and the price rises to 40¢, the position is worth about $1,600. If it falls to 10¢, it is worth about $400. Prices move on news, polls, data and statements, and they can move fast as the result gets close.

Since the account rules run on equity, these moves count before anything resolves. Liquidity matters too: in a thin market, the price on screen may not be available for your full order, and a large order can fill partly or at a worse price.

InteractiveTry it: YES and NO pricesMove the YES price and see the probability and the payoff.

When a price is worth taking

Compare the price with your own estimate. Buy YES at 62¢ when you believe the real chance is 70%, and each share is worth about 70¢ to you: an expected edge of roughly 8¢ before the fee. Believe it is 60% and the same trade has a negative edge, however likely the event looks.

  • Write your estimate down before you look at the price, so the market does not anchor you.
  • Subtract the opening fee from your edge; a small edge can disappear.
  • Remember that openings are only accepted inside a configured price band. Near-certain and long-shot prices can be closed but not opened.

Keep a short record of each estimate next to the price you paid and the result. After a few dozen trades it shows whether your estimates beat the market or only felt confident.

Questions

Why did the price move when nothing official happened?

Prices react to news, polls, data, statements and rumours as traders reassess the chance. The final result can still be unknown.

Is there a fee when I close a position?

No. The commission is charged on the notional of each opening trade only; closing is free.
