Traders doubt Trump will order an invasion of Iran

Traders price a qualifying offensive at 14% despite a biztoc line saying Trump decided to invade.

In one line: No American offensive to seize Iranian ground comes before 2027, and the contract stays under 18% through October despite biztoc's claim that Trump chose to invade.

Traders on Polymarket put the chance of a US invasion before 2027 at 14%, 4pp below the week's high of 18% on 20 Sep, even as a biztoc note claimed President Trump had already decided to invade. The contract is down 3pp over the week, from 17% on 18 Sep, and up 1pp in the last 24 hours.

The biztoc note, a market piece on 24 Sep from the financial news aggregator, says Mr Trump "decided to invade Iran", and the article claims energy prices soared. Firstpost reported the same day that lawmakers from both parties in Congress raised alarm over China's support for Iran, as Mr Trump courts Xi Jinping, China's leader.

The report and the price disagree, and the price is the more reliable signal. The rule pays "Yes" only if the United States "commences a military offensive intended to establish control over any portion of Iran", judged by "a consensus of credible sources". A decision is not a commencement, and one line in a bond note is not a consensus. Neither part of the rule is met. For this contract to pay, American forces must move to take and hold Iranian ground.

At 14%, the contract prices more risk of an offensive than the reporting supports, and it will probably resolve "No". The call is wrong if the contract closes above 18% on any day before 31 Oct, or if credible outlets report US forces advancing to seize Iranian territory before 31 Dec.
