Polymarket's contract on the blockade ending by traded in a one-cent band either side of its starting price through a night of strike reports, a tanker attack and a presidential remark against a deal.

Crude oil repriced overnight on reports of U.S. strike planning against Iran. The event contract most directly tied to the conflict's timeline did not.
Polymarket's contract on the blockade ending by traded at 19.5 cents early Thursday, implying about a 19.5% chance. Through the night it moved within a range of 18.5 to 20.5 cents and finished where it started.
The night it sat through
Over the same hours, Brent crude rose about $4 a barrel, or roughly 4%, to $104.20 from Wednesday's settlement. Reports citing two administration officials said the White House has asked the Pentagon for strike options against Iranian targets that could be used before the midterms, with no decision made. A tanker north of Qatar was hit by several projectiles, according to Britain's maritime trade agency. President Trump said at a rally that a deal with Iran "isn't really something that I want to do," while also saying of the war, "That war ends, it's going to be very soon."
Each of those items could plausibly move the odds of the blockade ending within three weeks. Together they produced no net change.
Why the contract may not react
One possible explanation lies in what the contract asks. It settles on whether the blockade ends by a date, not on whether fighting escalates. Strike planning could make an early end less likely by widening the conflict, or more likely if pressure forces a settlement, and the president's own remarks pointed both ways. Traders who see the news cutting in both directions have little reason to move the price.
Oil, by contrast, prices supply risk directly, and its overnight move also reflected a hurricane that has shut about a quarter of Gulf of Mexico output. The two markets are answering different questions.
What a 19.5% price says
At about one in five, the market treats an end to the blockade before November as possible but unlikely. That view has held through a run of headlines that moved oil several dollars, which suggests traders see the timeline as set by events the reports do not change.
Precision or Thin Liquidity?
One reading is that event traders are separating headline risk from the specific outcome their contract settles on, and that the flat price reflects precision rather than inattention.
Another reading is that thin overnight liquidity left the contract behind, and that it will reprice once U.S. hours bring more volume or once Washington or Tehran responds on the record.
What would move it
An official U.S. statement on the strike planning, any response from Tehran, or a break in the tanker attacks would be the first tests. A move outside the 18.5 to 20.5 cent band on any of them would show the market treating the news as decisive rather than ambiguous.
