Katie Zacharia out as Press Secretary by October 31 rises to 96.7% on Polymarket, on $337K traded

The Polymarket contract on whether Katie Zacharia will be out as Press Secretary by October 31 reached a market-implied probability of 96.7%, with $337K traded, in the Oct 16, 2026 update published at 2:24 PM ET. The reading reflects traders’ expectations, not confirmation of a personnel change.

What the figures establish

Both price and reported trading volume increased from the earlier snapshot supplied for the story. The material does not identify a news event behind the repricing or provide an announcement confirming Zacharia’s departure.

According to predictionbubbles.net, its market tracker refreshes prices from Polymarket and Kalshi every 15 minutes. It defines traded volume as cumulative activity, distinct from liquidity available on the order book or the value of positions that remain open.

The supplied predictionbubbles.net page explains that methodology but does not display the Zacharia contract or its settlement terms. The contract-specific figures therefore come from the supplied story update; the available source text does not independently establish those readings or the precise conditions required for resolution.

What it means for prediction markets

• Earlier comparison: The 1:54 PM lead on Oct 16, 2026 carried a 70.2% probability and $212K traded, below the subsequent 96.7% and $337K readings.
• Price is not confirmation: The latest probability shows a strongly one-sided market expectation, but it does not establish that the underlying event has occurred.
• Volume has limits: $337K in trading activity is not a measure of current liquidity. The October 31 deadline and the contract’s exact settlement rules remain central to interpreting the outcome.
