US strike on Colombia by December 31 priced at 28.5% on Polymarket, up 6 points, on $1.2M traded

Polymarket priced a US strike on Colombia by December 31 at 28.5%, up 6 probability points, with $1.2M traded, according to the supplied market update published Oct 21, 2026, at 3:24 PM ET. The higher price reflects a shift in traders’ assessment, not confirmation of military action.

The accompanying news summary identified no significant new platform headline in the preceding 30 minutes. Its search results recirculated previously handled material, leaving no fresh catalyst established by the supplied reporting.

What the data establishes

According to predictionbubbles.net, its market-movement tracker compares prices over 24 hours and refreshes every 15 minutes using data from Polymarket and Kalshi. The supplied page records a venue-data snapshot at 21 Oct 2026, 19:15 UTC.

The tracker measures changes in probability points rather than relative percentages. On that basis, the reported 6-point increase describes the size of the repricing, rather than a 6% relative gain.

Limits of the available evidence

The supplied predictionbubbles.net excerpt explains the tracker’s methodology but does not display the Colombia contract’s individual entry. The 28.5% price, 6-point move and $1.2M trading figure therefore come from the supplied headline, rather than a contract-level record visible in that excerpt.

The material also does not specify the period covered by the $1.2M figure, provide order-book depth or set out the contract’s resolution criteria. Those omissions limit what can be concluded about trading conditions and precisely which actions would qualify as a US strike.

What it means for prediction markets

• A repricing, not an event confirmation: The market assigns a higher probability to a strike, but the supplied reporting establishes no new military development.
• The catalyst remains unclear: The absence of a significant new headline in the preceding 30 minutes does not explain a move measured over a broader window.
• Volume needs context: The reported $1.2M traded does not, by itself, establish current liquidity or show how much trading accompanied the increase.
• Resolution terms matter: Without the contract’s criteria, the supplied material cannot establish which potential US actions would satisfy the market.
