Both Teams to Score Explained: How BTTS Betting Works on Polymarket

Both teams to score, often shortened to BTTS, is a bet on whether each team scores at least one goal. 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, only whether both teams got on the scoresheet.

That makes it a different question from who wins. A 1-1 draw and a 3-2 away win are both Yes. A 5-0 home win and a 0-0 are both No. Bettors use it when they have a view on how open a match will be but not on its result.

On Polymarket, both teams to score is a Yes and No market titled with the match, "Manchester United FC vs. Manchester City FC: Both Teams to Score". A Yes share pays $1 if both teams score and a No share pays $1 if either team does not. On 0xinsider the market sits in the Markets section of the match's event page, under Both Teams to Score, with first-half and second-half versions where Polymarket lists them.

The rules count the first 90 minutes 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, and if it is cancelled with no make-up game it settles 50-50. Check the rules on the market page for the resolution source.

A Yes price is the market's probability that both teams score. Yes at 54¢ is a 54% chance. Buy $100 of Yes at 54¢ and you hold 185 shares that pay $185 if both teams score, a profit of $85. Buy No at 46¢ and the same $100 holds 217 shares that pay $217 if either team fails to score.

To compare with a sportsbook, convert its odds to a probability. BTTS Yes at -125 in American odds or 1.80 in decimal odds is 55.6%; 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. On Polymarket the Yes and No prices add up to about $1, and the cost of trading is the spread between the best bid and ask.

Then read the price against the base rate. Across 13,071 settled Polymarket markets, both teams scored 54.4% of the time. Yes at 54¢ says this is an average match. Yes at 45¢ says one team is expected to struggle to score, and Yes at 65¢ says both attacks are expected to get through.

The league moves the base rate by ten points either way. Among competitions with 250 or more settled Polymarket markets, both teams scored 63.4% of the time in MLS, 62.9% in the Bundesliga, 59.3% in the Championship and 59.0% in the Brasileirão. The Premier League sat at 56.6% and La Liga at 56.4%. At the bottom, Serie A was at 46.6% and Argentina's Primera División at 44.6%.

Each of those rates rests on 250 to 450 matches and carries a half-width of five to six points, so treat them as a starting point, not a precise number. 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.

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 actually came in together in about 42% of those matches. A bettor 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 bettor who backs the draw is mostly backing both teams to score, and the guide at 0xinsider.com/learn/how-to-bet-on-soccer-polymarket covers the draw market in full.

The half markets are much less likely to settle Yes, because each half gives both teams less time. Both teams scored in the first half in 21.8% of 3,083 settled first-half markets, and in the second half in 36.7% of 1,930 settled second-half markets. The two samples are different sets of matches, so use each as its own base rate.

A first-half Yes at 20¢ is close to the average, and a second-half Yes at 37¢ is too. Both pay more than the full-match market when they land, and land less often.

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 know 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.

The largest bettors priced both teams to score about as well as the market did. An edge 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.
