April 27, 2026 - April 28, 2026, the price of the 86-87°F option rose from 32c to 48c before settling at 41c, driven by increasingly stable forecast data pointing to this temperature range as the resolution day approaches. April 26, 2026 - April 27, 2026, the 84-85°F option experienced significant volatility, rising from 20.5c to 33.5c before settling at 28.5c, driven by strengthening expectations of cooling from forecasted thunderstorms. April 26, 2026 - April 27, 2026, prices for the 88-89°F and 90-91°F options plummeted (e.g., 88-89°F dropped from 30.5c to around 10c). This was due to weather models reaching a stronger consensus on cooler temperatures caused by expected thunderstorms and rain on April 28, drastically reducing the probability of higher temperatures.

The rule strictly defines 'Beirut' as the 'municipality of Beirut', which is a specific administrative core, distinct from the broader 'Greater Beirut' area or suburbs like Dahieh (a Hezbollah stronghold). There is a risk of confusion where public perception sees operations in suburbs as 'entering Beirut', while the market resolves 'No'. The exclusion of aerial ops and undercover agents clarifies things, but 'troops on the ground' could still be contentious during brief raids or Special Forces incursions.

If Israeli ground forces physically enter the municipality of Beirut, it would mark a significant escalation in the Middle East conflict. Such an event would almost certainly trigger fears of regional oil supply disruptions (especially if Iran becomes more involved), driving up Crude Oil prices. Safe-haven demand would boost Gold, while global equities (like the S&P 500) would likely suffer a short-term sell-off due to increased geopolitical risk premiums. This is a highly tradable macro event.

There is a significant 'Sealed Indictment' risk. DOJ indictments against foreign heads of state are often sealed until they leave office (Petro's term ends in Aug 2026). If an indictment is filed but sealed by April 30, the market should resolve 'No' based on the 'announced' requirement. However, if media leaks the existence of a sealed indictment, it could trigger disputes under the 'credible reporting' clause. Additionally, 'Sovereign Immunity' for a sitting president makes a public formal charge by April 30 legally improbable.

If Petro is formally charged by the US while in office, it would be a Black Swan event for Colombia, causing political turmoil and fear of sanctions. Colombian assets would face severe sell-offs: Ecopetrol (EC), as the state-run oil major, would be hit hardest, while Bancolombia (CIB) and the Colombia ETF (GXG) would plunge due to spiking country risk premiums. Impact on broad US indices (SPX) would be negligible, but extreme for these specific regional assets.

April 26, 2026 - April 28, 2026, the price of the 76-77°F option surged from 11c to 43.5c, and the 74-75°F option rose from 10.5c to 31c, while 78-79°F fluctuated, rising from 4c to 31.5c before falling back to 11c. These movements occurred because, as the target date approached, weather forecasts confirmed the cooling effect of incoming rain and thunderstorms, adjusting the expected high down to the 74-77°F range.

The title broadly refers to Beijing, but resolution strictly relies on a single weather station (ZBAA) via Wunderground. Rounding to whole degrees and ignoring post-finalization revisions could cause disputes if equipment glitches or data synchronization delays occur.

April 26, 2026 - April 28, 2026, the price of the 22°C option surged from 22c to 41c, due to upward adjustments in weather forecast models for the high temperature as the resolution date approached. April 26, 2026 - April 28, 2026, the price of the 21°C option rose from 23.5c to 42.5c, as actual meteorological data indicated the temperature is most likely to land in this range. April 26, 2026 - April 28, 2026, the price of the 20°C option plummeted from 22c to 2.95c before bouncing back to 9.85c, as the likelihood of temperatures exceeding 20°C significantly increased over time, ruling out lower temperature probabilities.
