Russia capture all of Lyman by December 31, 2026 priced at 5.9% on Polymarket

Polymarket priced the prospect of Russia capturing all of Lyman by December 31, 2026 at 5.9%, down 4.6 percentage points over 24 hours, according to the supplied PredictionBubbles market summary. Reported trading volume was $295K.

The figures accompanied an update published on Oct 21, 2026 at 9:54 AM ET. They show a lower market-implied probability for the specified outcome, rather than confirmation of any change in control on the ground.

What the data establishes

According to predictionbubbles.net, its movers tracker compares prices over 24 hours and updates every 15 minutes using data from Polymarket and Kalshi. The supplied page records a venue-data snapshot of 21 Oct 2026, 14:12 UTC.

The tracker orders markets by the size of their probability-point changes, regardless of direction. Trading volume provides context but does not determine the ranking, so the 4.6-point decline and $295K traded measure different aspects of this market.

Limits of the signal

The supplied material contains no Lyman-specific battlefield reporting or identified catalyst for the decline. It also does not provide the contract’s detailed settlement criteria, order-book depth or a breakdown of trading activity. The available evidence therefore supports a report of repricing, not an explanation of why it occurred.

What it means for prediction markets

• Outcome specificity matters: The contract concerns capture of all of Lyman by December 31, 2026, not a broader assessment of the conflict.
• The move is in percentage points: The reported decline is 4.6 percentage points, not a 4.6% relative fall.
• Volume does not establish the cause: The $295K figure adds trading context, but cannot by itself show whether new information or trading dynamics drove the shift.
• Price is not verification: The 5.9% reading reflects market pricing; the supplied material does not independently establish battlefield conditions.
