Market probability
50.0%
Little changed over 24 hours
850 days until the event deadline
Deadline: December 31, 2028 at 6:59 PM ET

Too little market data to assess this move — treat the probability with caution.

This venue reports too little volume or book data for this market to judge the trading behind the price.

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?

Insufficient data

This venue reports too little volume or book data for this market to judge the trading behind the price.

Consensus stability

Has the market settled at the new probability?

Stable

The probability has held near its current level over the past several hours.

Contract clarity

Will the rules resolve without ambiguity?

High

The resolution rules are relatively specific, with a named source and a defined deadline.

What could move this market next?

  • The market's deadline arrivesDecember 31, 2028 at 6:59 PM ET

    The contract must resolve based on what has happened by this date.

Derived from the contract's own mechanics as of Sep 3, 12:24 PM ET. ProbCast does not list scheduled meetings, announcements, or data releases it cannot verify.
