Polymarket most-traded: Bills-Rams still first

Bills-Rams remains the most-traded market

Bills vs. Rams retained the top spot among Polymarket’s most-traded markets in the Oct 13, 2026 · 6:24 PM ET snapshot, with $8.7M in volume. Two League of Legends playoff markets followed at $7.9M and $7.3M.

The ranking puts a football matchup ahead of two esports playoff markets. The supplied summary does not identify the teams in either League of Legends market or specify the period covered by those market-level totals.

For the broader platform, Polymarket recorded $4.6B in contract volume over Sep 13-Oct 12, 2026, according to defirate.com. The outlet reported $2.3B in dollars paid for that period, distinguishing that measure from contract volume.

According to defirate.com, Polymarket accounted for 5% of prediction-market volume, with activity down 7% from the preceding 30 days. That platform-wide decline provides context for the leaderboard, but the supplied figures do not establish whether activity in the three leading markets increased or decreased.

What it means for prediction markets

• Sports and esports lead this snapshot: Bills vs. Rams ranks first at $8.7M, followed by League of Legends playoff markets at $7.9M and $7.3M.
• Volume is not a probability signal: The supplied totals show trading activity, not prices or implied chances of an outcome.
• Measurement matters: The $4.6B contract-volume figure and $2.3B in dollars paid are distinct measures. The leaderboard’s unspecified reporting window also limits comparisons with the Sep 13-Oct 12, 2026 platform totals.
