This market will resolve to "Yes" if the acting White House Press Secretary says the listed term during the next White House press briefing they participate in. Otherwise, the market will resolve to "No". Any usage of the term regardless of context will count toward the resolution of this market. Plural and possessive forms of the listed term will count toward the resolution of this market regardless of context; however, other forms will NOT count. Instances where the term is used in a compound word will count regardless of context (e.g. joyful is not a compound word for "joy," however "killjoy" is a compounding of the words "kill" and "joy"). If this market requires a specified number of mentions of a person’s first or last name, a full-name mention will count as one mention (e.g., if a market is about “Joe / Biden 5+ times,” a mention of “Joe Biden” will count once). AI-generated content will not be considered when resolving this market. If no such press briefing happens by April 30, 2026, 11:59 PM ET, this market will resolve to "No". This market refers to White House press briefings by the acting White House Press Secretary (https://rollcall.com/factbase/trump/topic/calendar/). Any press briefing by the acting White House Press Secretary will qualify. "New Media" press briefings or special briefings such as those including extra guests will be considered, so long as the acting White House Press Secretary is a listed participant. Impromptu press gaggles will not be considered for the resolution of this market; only events listed on the public schedule as briefings or announcements will qualify. The resolution source for this market will be footage of the relevant briefing.

Questions

What does the consensus price mean?

It is the price of a Yes contract that pays $1 if the outcome happens. A 14¢ price means traders put the chance near 14%. Where two venues list the same outcome, we blend their last prices, weighting the venue with more trading volume more heavily (neither counts for less than a quarter). When only one outcome can win, each venue’s prices add up to a little over 100% (its margin); the fair chance removes that margin so the outcomes add up to exactly 100%.

How is the payout worked out?

A Yes contract pays $1 if it wins, so at the best ask a $100 stake buys 100 ÷ ask contracts. At 18¢ that is about 555 contracts, paying $556 (5.56x) if Yes happens. Venue fees and price slippage on larger orders are not included.

Why do the venues show different prices?

Each venue has its own traders, fees and order book. Contracts can also settle on slightly different terms, which is why each row lists how closely the rules match.

Is a price gap an arbitrage?

Only when you can buy Yes on one venue below what someone pays for Yes on the other, after fees, and both contracts settle the same way. We show the executable bid and ask so you can check.

How fresh are these prices?

Venue prices refresh every few minutes, and the order book and live quotes stream continuously. Each venue’s card shows when we last observed it.
