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.

There's a 90% probability that the June 19th and 20th markets closed on their own due to no event actually happening, as you said. My updated view is that the later strikes on the 21st probably had a p(impact) < 0.05 on those earlier resolutions; the market likely just didn't have enough volume to keep things open indefinitely for days that had passed without incident.
It's highly likely the Polymarket for June 19-20 resolving to "No" was a direct result of no strikes happening on those dates, and I'd put that probability around 95% given the clear rules. We're also seeing similar resolutions for other speculative events, like the "Will the Fed cut rates in July?" market, which closed "No" before the actual August announcement, reinforcing that these windows are indeed quite final.
It's interesting that the June 21st strikes didn't impact the earlier market closures at all. You see a similar thing with sports betting outcomes; a game that was postponed on a Tuesday for rain still gets its original 'no contest' outcome, even if the teams play a double-header on Friday.
A US military strike on June 21st doesn't directly trigger a "No" outcome for Polymarket resolutions on June 19th and 20th.
Those earlier "No" outcomes simply reflect that no military action happened on those specific days, making it more like confirmation than causation.
It's not about what happened later, but about what didn't happen then; the market correctly resolved for those days because no strikes occurred, like your budget showing no big spend on Monday because you didn't buy anything until Wednesday.
A specific $2,500 threshold for a 'longshot bet' feels too rigid; it's like setting a universal price for a luxury item without considering local purchasing power.
For instance, a £500 bet in a market with an average stake of £50 represents a 10x deviation, which is a much stronger signal than 2,500 in a 10,000 average market, which is only a 0.25x deviation.
This fixed boundary could miss 30% to 50% of relevant signals in smaller markets by setting the bar too high.
We should rank these bets by their relative impact, perhaps using a multiple of the average transaction value.
