Iran seized two ships in the Strait of Hormuz amid rising tensions over oil supply routes, and the Polymarket contract for WTI crude oil hitting $160 in April sits at 0.8% YES.
Market reaction
The seizure comes as President Trump halted planned attacks, with no signs of peace talks restarting. On the WTI crude oil market, odds for hitting $160 in April dipped from 1% a day ago. The market has a daily face value of $49,622, but actual trading volume is $514. The price can move five points with just $1,955, meaning large orders can shift pricing substantially.
Why it matters
Iran’s actions in the Strait raise the risk of oil supply disruption. The contract has 68 days until resolution, and the term structure shows traders are pricing in the possibility of further Gulf disruptions that could move crude prices sharply. With trading volume this thin, even modest geopolitical updates could produce outsized price swings.
What to watch
At current levels, a YES share for WTI crude reaching $160 by April pays $1, a potential 125x return. That bet requires a belief in rapid conflict escalation or major supply disruption within days. Key catalysts: OPEC+ announcements, US military maneuvers in the region, or Iranian policy changes affecting shipping lanes. Rolf Habben Jansen’s next public statement on shipping traffic through the Strait is also worth monitoring.
