How the shares are counted
Which fights. Every UFC bout with a result on 212 cards from Oct 25, 2021 to Oct 24, 2026 (the last 5 years up to the newest result): 2,613 bouts. Results of a card are read 60 hours after the start of its date, so late corrections on Wikipedia settle first.
Groups as PROLINE+ settles them. KO/TKO includes disqualification (a finish); a technical decision counts as a decision; draws and no contests are void when the market has no price for them, so they are left out of the shares and shown apart.
Three or five rounds. A decision tells how many rounds were scheduled; so does a finish in round 4 or 5. For other finishes we take the main event and title fights as five rounds and the rest as three. On the 1,229 decisions of the period this rule gives the right number of rounds 99.3% of the time.
Small samples. A division needs 30 fights before its shares are shown; women’s featherweight and five-round fights of a single division are often below that.

How UFC fights end and how long
KO/TKO
A fighter is knocked out, or the referee stops the fight. For bets, this counts as a finish.
Submission
A fighter taps out from a hold or choke. Also a finish.
Decision
No finish: the judges' scorecards decide. On PROLINE+, a technical decision is also settled as a win by decision.
Draw
The judges score the fight even. On PROLINE+, if no draw price was offered, bets are void.
Round length
5 min roundsEach round lasts 5 minutes, with 1 minute of rest between rounds (Unified Rules). The tool shows three- and five-round fights separately.
