While public health data is a standard metric, a prediction market specifically targeting the exact count of measles cases (2000 or 2200) by a specific date (April 30, 2026) is relatively niche. It is not top-tier mainstream news but holds interest within specific medical or epidemiological circles.

April 22, 2026 - April 23, 2026, the price of the 1800 option plummeted further from 27.5c to 16c, and the newly listed 1775 option dropped to 43c. The reason is that as the April 30 deadline approaches, the latest US CDC data indicated a sharp slowdown in the growth rate of new measles cases, drastically reducing expectations of surpassing 1800 cases and shifting the focus down to around 1775. April 19, 2026 - April 21, 2026, the price of the 1800 option dropped steadily from 40c to 27.5c. The reason is that as the end of the month nears, updated CDC data showed a lower-than-expected growth in new cases, weakening market confidence in surpassing 1800 cases. April 16, 2026 - April 18, 2026, the price of the 1850 option plunged from a peak of 31.5c to 6c, mainly because the weekly data release confirmed a slowdown in the outbreak, shattering panic expectations of high case counts. April 3, 2026 - April 4, 2026, the price of the 2000 option plunged from 45.5c to 32.5c, stabilizing around 30c in the following days, mainly because CDC data updates showed a slowdown in new cases, heavily dampening market confidence in surpassing 2000 cases. March 28, 2026 - April 1, 2026, price fluctuations for all options were within 10c, indicating relatively stable market expectations.

The rules have a very strict and specific definition of 'unrestricted,' explicitly excluding vague statements about 'openness,' 'de-escalation,' or 'security.' Because diplomatic language is often ambiguous, an unclear statement or conditional pledge by Iran could easily trigger resolution disputes.

The Strait of Hormuz is the world's most critical oil transit chokepoint. An agreement by Iran to allow unrestricted shipping would deeply alleviate energy supply concerns since the conflict began, causing a sharp decline in crude oil's geopolitical risk premium (highly bearish for oil). Meanwhile, reduced risk aversion would pressure Gold, while lower energy costs and tangible de-escalation would act as a direct positive catalyst for broad equities like the S&P 500.

Between April 20, 2026 and April 23, 2026, the price of Option_'Yes' plummeted from 29.5c to 9c, as market expectations cooled off continuously and significantly with the deadline approaching and no signs of a diplomatic breakthrough. Between April 15, 2026 and April 16, 2026, the price of Option_'Yes' dropped sharply from 45.0c to 29.5c, likely due to rapidly fading optimism regarding a short-term agreement to lift restrictions.

The rules contain several strict limitations: only verbal mentions within the specified timeframe that are recorded (audio/video) and publicly accessible count. Written mentions (including Truth Social posts) and AI-generated audio/video are invalid. Re-posting older videos also does not count, and only the listed terms (with plural/possessive exceptions) qualify. These restrictions mean that a flurry of written posts by Trump mentioning these terms would still resolve to 'No', posing a significant divergence from literal intuition.

Predicting which specific Trump-named things Trump will mention from a list of highly eccentric and specific options (e.g., 'Mount Trump', 'Gulf of Trump', 'Trump-Class') is highly unusual. It is not a standard political or policy forecasting market, but rather a novelty market focused closely on his personal quotes and impromptu remarks.

April 20, 2026 - April 23, 2026: The price of Trump Turnberry surged from 23.5c to a peak of 52c before retreating to 37c, as market expectations of mentions related to his Scottish golf course rapidly heated up and then rationalized. April 20, 2026 - April 23, 2026: The price of Trump Tower / Trump Towers rebounded from 28c to 44c, reflecting renewed expectations of him mentioning the landmark building in recent remarks. April 20, 2026 - April 23, 2026: The price of Trump Force One rose from 25.5c to 42c, driven by increased probability of mentioning his private jet amid a busier campaign schedule. April 20, 2026 - April 21, 2026: The price of Trump Organization surged from 6.5c to 54c, likely triggered by new legal or financial news concerning his core business empire, raising market expectations of a mention. April 19, 2026 - April 20, 2026: The price of Trump Tower / Trump Towers plummeted from 49.5c to 28c, possibly because he notably avoided mentioning the building in recent rallies or speeches. April 18, 2026 - April 19, 2026: The price of Trump National / Trump International dropped significantly from 53c to 28c, reflecting diminished market confidence in him mentioning his golf course brand in the near term. April 18, 2026 - April 19, 2026: The price of Trump International Airport / Trump Airport crashed from 54.5c to 21.5c, indicating that earlier hype surrounding airport naming proposals quickly faded. April 17, 2026 - April 18, 2026: The price of Donroe Doctrine / Trump Doctrine plummeted from 60c to 41c, and continued to fall, as his recent foreign policy rhetoric likely deviated from this specific term. April 17, 2026 - April 18, 2026: The price of Trump Organization fell sharply from 64c to 40c, potentially due to failed expectations of verbal mentions during that period. April 16, 2026 - April 17, 2026: The price of Trump National / Trump International spiked from 45c to 61c, likely anticipating mentions related to an upcoming golf event or activity. April 16, 2026 - April 17, 2026: The price of Trump Organization surged from 43.5c to 64c, coinciding with potential major news releases regarding his company's operations.

If this event occurs (resolves Yes), it would trigger a structural collapse in global financial markets. TSMC (TSM) and the semiconductor supply chain (NVDA, AAPL, etc.) would be hit hardest, causing a violent crash in the Nasdaq. Safe-haven assets like Gold, DXY, and Crude Oil would surge. This prediction market serves as a prime 'doomsday hedge' instrument.

The Fed's interest rate decision directly dictates the cost of capital, profoundly impacting all major asset classes. An unexpected resolution (e.g., a surprise cut or hike) would trigger immediate volatility in US Treasury yields, subsequently driving repricing in the Dollar Index (DXY), Gold, and equities (S&P 500). Given the timeline (July 2026), the market sensitivity to policy shifts at that economic juncture is likely high.
