Brian Armstrong is scheduled to participate in Coinbase's product showcase on December 17, 2025 (https://x.com/brian_armstrong/status/1990798715997810957). This market will resolve to "Yes" if Brian Armstrong says the listed term during his appearance at the named event. Otherwise, the market will resolve to "No". Pluralization/possessive of the listed term will count toward the resolution of this market. 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 audio or video will not count toward this market's resolution. This market is explicitly about Brian Armstrong's appearances at the "Product Showcase: Coinbase System Update 2025" event (https://investor.coinbase.com/events-and-presentations/events/event-details/2025/Product-Showcase-Coinbase-System-Update-2025-Cafj9fkLvm/default.aspx). Speeches, events, or comments that occur outside of the specifically listed events will not qualify toward this market's resolution. If the events contain Q&As, it will count toward the resolution of this market. If this event is definitively cancelled, or relevant footage is otherwise not aired by December 17, 2025, 11:59 PM ET, this market will resolve to "No". The resolution source will be video of the events. Only remarks which are broadcast or streamed live will count toward this market's resolution.
