April 21, 2026 - April 22, 2026, market expectations underwent a drastic reversal due to new data or sentiment indicating a significant drop in approval ratings. The '39.0–39.4' option skyrocketed from 3.5c to 59.9c, and '38.5–38.9' surged from 1.75c to 39.5c. Conversely, the formerly dominant higher brackets crashed: '39.5–39.9' plummeted from 57.5c to 8.5c, and '40.0–40.4' collapsed from 53.5c to 0.55c. April 20, 2026 - April 21, 2026, the '39.0-39.4' option fell from 26c to 9c, while '40.0-40.4' rose from 25.5c to 41.5c, indicating that with new data or confirmed expectations, the market believes the approval rating tilts towards the upper bracket. April 18, 2026 - April 19, 2026, as new polling data was digested and the resolution date neared, market expectations reverted toward the median. The '40.0-40.4' option fell from 40.5c to 27.5c, and the '40.5+' option crashed from 20.3c to 1.6c. Concurrently, the '39.5-39.9' option absorbed this probability, climbing from 35.5c to 46c. April 17, 2026 - April 18, 2026, the '40.0-40.4' option surged from 27c to 40.5c, and the '40.5+' option jumped from 4c to 24c, while the '<38.5' option crashed from 27c to 5c. This sharp movement was driven by new polling data feeding into the Silver Bulletin aggregator, pushing Trump's expected approval rating significantly higher.
