Polymarket
This market tracks whether Donald Trump's approval rating will decline to 38.0% or lower at any point between late April and the end of May 2026. On Polymarket, the probability of the 38.0% threshold being reached stands at 41.9%, while the probability of an even steeper decline to 37.0% is at 3.0%. Resolution will be determined using Silver Bulletin's approval rating poll aggregator, with RealClearPolitics as a fallback source if Silver Bulletin becomes unavailable. Watch for the finalized approval rating data published by June 4, 2026, which will determine whether the market resolves based on readings through May 31.
Prediction market odds on Polymarket reflect traders' collective assessment of Trump's approval trajectory, often incorporating polling data, recent political events, and economic conditions faster than traditional polls update. While polling averages measure current sentiment through survey samples, prediction markets price forward-looking expectations with financial incentives for accuracy. Market odds may diverge from polls if traders anticipate approval shifts due to upcoming legislative votes, economic reports, or scandals. Comparing the two reveals whether markets are pricing in approval changes that polls have not yet captured.
The market resolves on May 31, 2026. Resolution is determined by Trump's official approval rating as measured at that time, compared against the predefined thresholds embedded in each outcome. The outcome that matches or most closely reflects the final approval figure will be deemed correct. Traders holding shares in the winning outcome receive their payout, while losing positions expire worthless. The resolution hinges on the accuracy of the approval metric used and the precise timing of measurement on the resolution date.
Major political and economic events will likely shift approval expectations and market odds. Legislative victories or defeats, changes in unemployment or inflation, foreign-policy crises, or scandals can rapidly alter public sentiment. Media coverage of Trump's statements or actions, Supreme Court rulings affecting his interests, and developments in ongoing investigations may also influence approval. Seasonal political dynamics, midterm campaign intensity, and shifts in partisan polarization could compress or expand approval swings. Traders monitor real-time polling releases and news cycles to adjust positions, causing price movements that reflect evolving approval forecasts.
