The probability that Mark Sutcliffe will win the 2026 Ottawa mayoral election plunged 44.0 percentage points over the past 24 hours, falling from 78.5% to 34.5% on Polymarket. This dramatic shift in market pricing reflects a substantial change in sentiment among traders.
Whale activity moved in concert with the price action, with 23 unique whales participating in the last 24 hours. These whales executed an equal amount of buy and sell volume, each totaling $5K, but their net flow skewed $193 toward NO contracts, indicating a modest but clear preference against Sutcliffe’s victory.
Market liquidity remains modest, with total 24-hour volume at $6K and lifetime market volume at $16K, involving 181 unique traders to date. The alignment of whale flow and price movement suggests that large traders are reinforcing the market’s reassessment rather than contradicting it.
This rapid repricing and supporting whale behavior signal a significant re-evaluation of Sutcliffe’s chances in the Ottawa mayoral race. The converging data points mark a shift in market consensus, emphasizing growing doubt about his electoral prospects as reflected in Polymarket’s pricing dynamics.
