The rules define 'military action' very narrowly and strictly. It must be aerial bombs, drones, or missiles that actually impact Iranian soil. Intercepted attacks, cyberattacks, artillery, or ground incursions do not qualify. Additionally, a strict 3-day deadline for credible confirmation applies. There is a high risk of misinterpretation for those who only read the title.

A direct Israeli military strike on Iranian soil would severely escalate Middle East tensions, triggering fears of global energy supply disruptions and causing a significant spike in Crude Oil prices. Simultaneously, this geopolitical shock would spark a strong risk-off sentiment, driving capital into safe-haven assets like Gold, while causing a notable drop in broad global equity indices such as the S&P 500.

April 14, 2026 - April 17, 2026, the 'April 21' option price continued to plummet from 20.5c to 4.5c. As time progressed without a direct Israeli retaliatory strike and amidst heavy international diplomatic pressure, the market deeply priced in the expectation that a short-term strike would not occur. April 12, 2026 - April 15, 2026, the 'April 14' option plummeted from 25c to ~1c because its deadline passed without a qualifying strike. April 11, 2026 - April 12, 2026, the 'April 14' option surged from 11c to 25c, and the 'April 21' option climbed from 25c to 44.5c, due to intensified market fears of a potential retaliatory military strike over the weekend. April 10, 2026 - April 11, 2026, the 'April 14' option dropped from 25c to 11c, and the 'April 21' option fell from 32.5c to 25c, reflecting a brief expectation of de-escalation. April 8, 2026 - April 9, 2026, the 'April 14' option dropped from 43c to 17.5c, and the 'April 21' option fell from 59.5c to 38.5c, due to the fading of initial panic and potential diplomatic interventions tempering short-term expectations.

The trap lies in: 1) Merely referencing violations isn't enough; it must explicitly declare the ceasefire over. 2) Replacing it with a new agreement without direct hostilities won't qualify as an end. 3) Reality doesn't matter; only official announcements count (from the US government or Trump's posts). The strict requirement for definitive language makes 'Yes' resolutions tricky.

The end of a ceasefire between the US and Iran would signal a severe escalation in Middle East conflict. This would directly cause Crude Oil prices to spike due to supply disruption fears. Gold would also rise as a safe-haven asset, while broad equities (S&P 500) could face downward pressure due to geopolitical risk and inflation fears from higher oil prices.

April 14, 2026 - April 17, 2026, the Yes price for April 21 plummeted from ~21.5c to 5.5c, and April 18 dropped from ~13.5c to 0.95c. This occurred because, as the deadlines approached without any official signals of a breakdown, market expectations for a near-term termination announcement cooled significantly, leading to rapid time-value decay. April 12, 2026 - April 16, 2026, the Yes price for April 21 plummeted from 37c to 8c, and April 18 dropped from 29c to 1.7c, driven by the absence of substantive breakdown declarations as the deadlines neared, causing panic selling. April 11, 2026 - April 12, 2026, the Yes price for April 21 rose from 25.5c to 37c, and April 18 rose from 19c to 29c, likely due to weekend localized frictions briefly heightening fears of the ceasefire collapsing. April 9, 2026 - April 12, 2026, the Yes price for the April 18 option rose from 18.5c to 29c as the market anticipated increased pressure from localized frictions, driving up mid-term option prices. April 8, 2026 - April 9, 2026, the Yes prices for all options plummeted. This sharp decline occurred because the market initially overestimated the probability of a rapid collapse right after the agreement, and subsequently revised expectations downward.

Predicting the exact number of tweets a celebrity makes over a random two-day period is a classic novelty/entertainment market. The general public does not typically ponder or forecast such bizarre metrics.

Direct military conflict and ceasefire statuses between the US and Iran significantly impact global macro assets. Crude Oil is highly sensitive to Middle East supply risks and the Strait of Hormuz, meaning a ceasefire extension would drastically reduce geopolitical risk premiums. Concurrently, safe-haven assets like Gold and broader equity indices (S&P 500) would be directly moved by major shifts in market risk sentiment.

April 17, 2026 10:23 - April 17, 2026 13:38, the Yes price of the 'April 21' option surged from 78c to 90.5c, as the failure of the short-term April 18 target led market capital and optimistic expectations to concentrate heavily on the final April 21 deadline, betting that both sides will ultimately reach an agreement by then. April 16, 2026 17:03 - April 17, 2026 10:23, the price of the 'April 21' option fluctuated narrowly between 76.5c and 82.5c, as the final deadline approached and the market waited for further official confirmation, leading to caution among traders. April 16, 2026 15:58 - April 17, 2026 07:08, the price of the 'April 18' option dropped further from 24c to 10.5c, as the extreme proximity of the deadline without official progress dashed hopes for a short-term agreement. April 16, 2026 00:48 - April 16, 2026 15:58, the price of the 'April 21' option rebounded from 69.5c to 83.5c, reflecting renewed market optimism for an overall extension before the final deadline, despite short-term setbacks. April 16, 2026 05:08 - April 16, 2026 10:33, the price of the 'April 18' option retreated significantly from 35c to 16c, as the approaching deadline without substantive official breakthroughs suppressed short-term expectations. April 16, 2026 00:48 - April 16, 2026 05:08, the price of the 'April 18' option quickly rebounded from 19c to 35c, likely due to new signals of short-term negotiation progress that reignited hopes for an agreement before the 18th. April 15, 2026 22:38 - April 16, 2026 00:48, the price of the 'April 18' option plummeted from 41.5c to 19c, as the White House denied requesting an extension, combined with negative remarks from Trump and US naval actions, crushing short-term optimism. April 15, 2026 17:13 - April 15, 2026 23:43, the price of the 'April 21' option sharply retreated from 88.5c to 71c, because earlier optimistic rumors regarding diplomatic breakthroughs were not officially confirmed, cooling market sentiment and prompting aggressive profit-taking. April 15, 2026 09:38 - April 15, 2026 17:13, the price of the 'April 21' option surged straight from 69c to 88.5c, due to strong signals suggesting major breakthroughs in the US-Iran ceasefire negotiations.

There is a significant rule trap. Even if hostilities actually resume or actions inconsistent with the ceasefire occur (e.g., closing a strait), the market will resolve to 'No' unless the US government or Trump explicitly labels it a 'breach' or 'violation' of the ceasefire in their statement. Additionally, breaches solely attributed to Israel do not qualify.

This is a geopolitical prediction. While US-Iran conflicts are common macro topics, betting on whether a ceasefire breaks within a specific tight window, contingent strictly on the 'official phrasing' of the announcement, adds a level of novelty and specific conditional constraints.

An official announcement that the US-Iran ceasefire has broken would trigger severe market panic. Crude Oil prices would experience a structural spike due to Middle East geopolitical risks and supply disruption threats. Safe-haven assets like Gold and US Treasuries (driving the US 10Y Yield down) would see aggressive bidding. Concurrently, risk assets like the S&P 500 would face a massive downward shock.

2026-04-14 to 2026-04-17, the Yes price of the April 21 option continued to decline from 28.5c down to 10c. The reason is that as the deadline rapidly approaches without any official statements from the US or Trump regarding a ceasefire breach (and with US officials actively refuting Iran's claims of a US violation), accelerating time decay has significantly eroded the risk premium. 2026-04-12 to 2026-04-14, the Yes price of the (now expired) April 14 option plummeted from 22.5c to 1.2c due to the extreme proximity to its deadline without any official announcements, causing the market to heavily discount the likelihood of a sudden incident.
