Traders speculated that significant civil unrest or anti-government protests erupted across Iran, driving the largest single-day jump in regime collapse odds. The 16.5 percentage point surge suggests reports of widespread demonstrations or potential military defections may have emerged. Market participants appeared to reassess the stability of the Iranian government, with Yes contracts briefly approaching even odds as uncertainty about the regime's durability increased sharply.

Traders speculated that Iranian authorities successfully suppressed whatever instability had rattled markets earlier in the week. The 15-point drop in regime collapse odds indicates reports of restored order, possibly through security force deployments or opposition leadership arrests. Combined with the prior day's selloff, markets moved decisively toward regime survival expectations, with Yes odds falling nearly 23 points over roughly 36 hours as the crisis narrative faded.
