This market will resolve according to the next individual who the White House announces has been picked to be the White House Press Secretary who replaces Katie Zacharia by December 31, 2027, 11:59 PM ET. A person being announced as an acting or interim holder of the position will not count for purposes of this market. In the event that no individual is chosen to replace Katie Zacharia, or the role is abolished, by December 31, 2027 at 11:59 PM ET, this market will resolve to "Other". Once a qualifying announcement has occurred, subsequent withdrawals or replacement announcements will not affect resolution. The primary resolution source for this market will be official information from the White House and Donald Trump, however a consensus of credible reporting may also be used.
The contract must resolve based on what has happened by this date.

Research signals — these models are still accumulating the history needed for full validation, and they can disagree with the headline read. Model confidence: low · expected error ±18 pts.
Thin book and/or wide spread. Small orders can move this price disproportionately, so any single print is noisy and easily overread.
Read with caution —Read the latest price with caution; conditions make it an unreliable summary right now.
Short-term motion of the price line (~1h), distinct from the environment above — not a prediction of the final outcome.
Secondary read: leaning toward Trading normally.
A read-only classification of the market environment — how much weight the current price deserves as a read of consensus. It describes conditions, never a trade.
