Repeat the following until only one remains: Take the top two highest percentages and eliminate whichever loses the matchup between the two. The survivor is the winner.

The display percentage is used (rounded to the nearest percentage point).

The following are tiebreaker rules (they also apply when there are less than 5 remaining, the numbers are just shifted.)

If there's a tie between 1/2/3 and no cycle, the one that loses against the other two is eliminated first. (if there are 5 at first, this leaves the one that beats the other two to win at the current moment but lose immediately after since every item has 2 things it wins against and 2 things it loses against, so it actually only matters what the winner is between 4/5.)

If there's a three-way cycle between 1/2/3, all three are eliminated.

If there's a tie between 2/3 or 2/3/4 or 2/3/4/5 the losers to 1 out of 2/3/... are eliminated. If there are no losers to eliminate, 1 is eliminated.

If there's a 3-way, 4-way, or 5-way tie between all remaining options, the market resolves N/A.

Example order (no ties): Rock; Scissors; Paper; Lizard; Spock

Rock vs. Scissors: Rock crushes Scissors

Rock vs. Paper: Paper covers Rock

Paper vs. Lizard: Lizard eats Paper

Lizard vs. Spock: Lizard poisons Spock

Lizard wins!
