This event can settle before an argument date exists and says nothing by itself about which side ultimately wins. At the October 4, 2026 market snapshot, December 31 carried a 34% Yes price. Other open contracts included October 31 at 4.5%.

The official docket or orders list must confirm the grant.

The event URL’s July wording is not the open child’s deadline.

A petition filing, lower-court conflict, stay or denial of review does not establish the required grant. The next useful checks are official Supreme Court orders and docket; subject matter covered by the case; grant rather than petition or decision. The linked primary references make the process and named data source inspectable.

Their Yes prices should not be added into a single winner probability, and the highest Yes price is not automatically the most informative question. The event had approximately $992,394 in total traded volume at observation. That is a record of turnover across this event, not a count of distinct people, a search-volume estimate or proof that every child contract is easy to trade. The analytical quote is fixed to the timestamp shown here; later live prices can differ.

A view merely agreeing that this is plausible does not show that the price understates it. The probability, rule and remaining time all have to be compared.
