Both teams to score explained: how BTTS betting works on Polymarket

When a match settled No, the usual reason was a clean sheet at one end and a goal at the other: 84.5% of the No matches were wins to nil, and only 15.5% were 0-0. Buy No and you are mostly backing one defense to hold for 90 minutes against an attack that scores.

Both teams to score, often shortened to BTTS, asks whether each team scores at least once. Yes wins on 1-1, 2-1 or 3-2. No wins on 0-0 and on any win to nil: 1-0, 2-0, 4-0. The winner does not matter, so a 1-1 draw and a 3-2 away win both settle Yes, and a 5-0 home win settles No.

So price No from the weaker attack. The question is how likely the team least likely to score is to be shut out, and a match you expect to be one-sided can be a better No than a match you expect to be dull.

Polymarket refunded 33 of the 13,706 both-teams-to-score markets with a kickoff from October 2025 to September 13, 2026. Almost every other one settled Yes or No on the 90 minutes. The rules count regular time plus stoppage time. Extra time and penalties do not count, so a cup tie that is 0-0 after 90 minutes settles No even if both teams score in extra time.

If the match is postponed, the market stays open until it is played; if it is cancelled with no make-up game, it settles 50-50. The market is a Yes and No market titled with the match, "Manchester United FC vs. Manchester City FC: Both Teams to Score", and a Yes share pays $1 if both teams score.

On 0xinsider the market sits in the Markets section of the match's event page, under Both Teams to Score. The section is part of Pro; without Pro it shows sample data.

Before kickoff, the Yes price ran a little cheap. Across 10,182 markets from April 2 to October 9, 2026, both teams scored 54.5% of the time at an average Yes price of 53¢: a gap of 1.5 points, give or take 0.97. That clears zero, and it is about the taker fee. Buying Yes at 53¢ by taking the ask costs 1.25¢ a share in fee. A resting limit order pays none and keeps the gap.

A Yes price is the market's probability that both teams score. Yes at 54¢ is a 54% chance, and $100 buys 185 shares that pay $185 if both teams score. A sportsbook's odds convert the same way: Yes at -125, or 1.80 in decimal odds, is 55.6%, and No at +100, or 2.00, is 50%. The two add up to 105.6%, and the 5.6 points over 100 is the book's margin. The odds calculator strips it to a no-vig price in cents.

Then read the price against the base rate. Both teams scored in 54.4% of the study's 13,071 settled markets and in 52.7% of the 1,620 matches since, give or take 2.43 points, so the rate held. Yes at 54¢ calls this an average match. Yes at 45¢ says one team is expected to struggle to score.

The league moves the base rate by up to 10 points either way, from MLS at the top to Argentina's Primera División at the bottom. Each rate rests on 250 to 450 matches and carries a half-width of 4.7 to 6.1 points, so the middle of the table is noise.

The ends are not. MLS, the Bundesliga and the Championship sit above the overall rate by more than their half-widths, and Serie A and Argentina sit below it by more than theirs. Start a Bundesliga price from the league's rate, not the overall one, and a Serie A Yes at the overall rate is priced for goals that league does not usually produce. The full table is in the both teams to score study.

Both teams to score and Over 2.5 goals usually land together. On 12,704 settled Polymarket matches with both markets, the match went over 2.5 goals 77.9% of the time when both teams scored and 22.4% of the time when one did not. Once both teams have scored the match has two goals and needs one more; if one team does not score, the other has to score three.

So do not treat them as two separate views. Priced as if they were independent, a 54% chance of both teams scoring and a 53% chance of Over 2.5 would combine to about 29%. The two came in together in about 42% of those matches. A trader who likes both is making one bet on an open, high-scoring match, and a combined bet on the two should be priced that way.

Draws come mostly from matches where both teams score. On 12,318 settled matches with both markets, 34.4% of the matches where both teams scored ended level, against 15.5% of the matches where one did not. A match where one team does not score can only be drawn 0-0.

Across those matches, about 7% ended 0-0 and about 19% ended in a scoring draw, 1-1 or higher. A trader who backs the draw is mostly backing both teams to score, and the soccer guide covers the draw market in full.

A first half without both teams scoring settles less than it looks. In 3,610 matches where both teams had not scored by halftime, both had by full time in 42.8% of them, give or take 1.61 points. Price a live Yes at halftime on the score and the attacks, not on a first half that has already gone.

The half markets settle Yes far less often, because each half gives both teams less time: 21.6% of 4,666 settled first-half markets and 32.2% of 3,882 second-half markets from June to October 9, 2026. The chart at the top of this guide shows 36.7% for the second half, counted on the first 1,930 markets; on twice the sample the rate is lower, so use the newer number.

Polymarket also lists halftime result markets on some matches: one for each team leading at halftime and one for a draw at halftime, of which exactly one settles Yes. Across 5,741 settled draw-at-halftime markets, the match was level at the break 43.1% of the time, the most likely single halftime result.

A halftime lead is worth a lot. A team leading at halftime won 75.4% of 3,530 settled matches, drew 16.9% and lost 7.8%. A level score at halftime tells you less: of 2,415 matches level at the break, 37.4% ended level. The live prices at halftime already reflect the score, so these numbers are a check on a live price, not a reason to bet one.

Not by default. From April 2 to September 13, 2026, large Polymarket buyers of both teams to score Yes paid 54.2¢ on average and won 57.2% of the time, 2.91 points ahead of the price. Buyers of No paid 58.4¢ and won 57.9%, 0.49 points behind. Resampling markets, both intervals include zero: Yes from minus 7.12 to plus 12.43, No from minus 10.71 to plus 8.83.

Yes leans cheap, by about the fee, and No offers nothing extra. An edge beyond that has to come from knowing something the price does not: a team missing its first-choice striker, a side that has to chase a result, a keeper change. Compare the price with the league's rate and with the match's Over 2.5 price, and bet when your view of this match differs from the market's.

Polymarket listed both teams to score on 2,919 of the 3,083 soccer matches with a result market from September 11 to October 10, 2026, and the goals line drew 13 times its volume. Read a both-teams-to-score price beside the match's Over 2.5 price: the goals line is where the money sets the odds on how many goals the match will have.
