Deadline: August 31, 2026 at 7:59 PM ET

The move lacks solid trading support — treat the new probability with caution.

The pricing has weak support: moderate trading volume. The probability moved another 16 points in the past hour — the market is still repricing.

How credible was the move?

Three separate questions — a move can be genuine while the latest price is still settling. Methodology →

Move validity

Is the move backed by real trading and depth?

Weak

The pricing has weak support: moderate trading volume.

Consensus stability

Has the market settled at the new probability?

Unsettled

The probability moved another 16 points in the past hour — the market is still repricing.

Contract clarity

Will the rules resolve without ambiguity?

Medium

Moderate resolution risk, driven mainly by no resolution basis.

Recent trade activity$198.3 traded

From the latest trade tape (most recent 200 prints) — a live activity sample, not a lifetime total.

Why the odds moved

The probability fell 28.2 percentage points over the last 24 hours (45.2% → 17.0%).

No verified catalyst has been linked to this move yet. ProbCast does not attribute moves to news without evidence connecting the timing of a specific report to the repricing.
