On Polymarket, the only major prediction platform tracking the 2026 Colombian presidential election, traders have priced Ivan Cepeda Castro's victory at 12%, implying an 88% probability that another candidate will prevail. The $3.3 million in volume on the market indicates significant trader interest, though the absence of data from Kalshi and Manifold limits cross-platform comparison. Cepeda Castro, a senator from the leftist Historic Pact coalition, has been a prominent figure in Colombian politics, but the market's low odds reflect skepticism about his ability to consolidate support or overcome rivals in a fragmented political landscape. No specific external trigger was identified in today's news flow to explain the current probability, which has remained relatively stable in recent weeks. The 12% figure suggests traders see him as a plausible but unlikely contender, with the field likely favoring more centrist or conservative alternatives as the 2026 campaign season approaches.
