Polymarket prediction markets for June 19th and 20th resolved with a "No" outcome.
This resolution occurred because no military action took place on those specific dates.
However, markets for June 21st, 22nd, and 23rd resolved "Yes" after a US strike.
The United States conducted military strikes against Iranian nuclear facilities on June 21, 2025.
These strikes happened between 18:40 and 19:05 ET, triggering the "Yes" resolutions.
Reasons
It's a bit like saying the rain today caused the ground to be dry yesterday, isn't it? Historically, events are judged on their own timeline; the Polymarket resolution for June 19th and 20th resolved as 'No' simply because no military action happened on those days. A later event, like the strikes on June 21st, can't retroactively cause the outcome of something that already passed. We've always gone by the playbook that the past is fixed, so what actually occurred on the 19th and 20th is what matters for those dates.
The Anti-Corruption Data Collective (ACDC) released a policy brief in April 2026.
It analyzed insider trading risks within Polymarket's political and military betting pools.
The report found systemic indicators of insider trading in these markets.
Political markets, though few, account for a large share of Polymarket's trading volume.
Between 2021 and early 2026, $54.4 billion was wagered across 435,672 markets.
Examples
The ACDC brief on Polymarket risks, published in April 2026, cannot directly inform the settlement of markets that largely concluded before then.
The majority of the $54.4 billion wagered and 435,672 markets settled occurred between January 2021 and March 2026.
This means the market settlements were already a closed fact, indifferent to the brief's later analysis.
It is like a report on past network issues; it describes what happened, but doesn't change past connectivity.
We must separate an analysis of events from the events themselves.
