Trump Election Odds Drop 5% After Debate Performance

What happened

Polymarket odds for Donald Trump winning the 2028 presidential election saw a sharp decline overnight, dropping from 52.5% to 47.3% — the largest single-day move on this market in over a month. The sell-off was triggered by a widely criticized debate performance where Trump struggled with policy specifics and appeared unprepared on key economic questions.

Trading volume surged to $2.1M in the 24 hours following the debate, with large whale-tier traders ($500K+ volume) leading the sell-side. On-chain data shows at least three whale wallets exited their Trump YES positions entirely.

Merlin’s take

This is a significant repricing but not necessarily a trend reversal. Trump markets have shown resilience after previous dips, bouncing back within 3-5 days in 4 of the last 6 corrections. The key level to watch is 45% — if odds break below that, it signals a more fundamental shift in market sentiment.

Smart money is split: insider-score traders (Merlin Insider Score >70) are roughly 50/50 on direction, suggesting genuine uncertainty rather than a one-sided information advantage. For traders looking to enter, the elevated volume creates good liquidity for building positions in either direction.
