This market will resolve to "Yes" if Tristan Buckmaster files a lawsuit against OpenAI, or any of its subsidiaries, executives, or employees, by 11:59 PM ET of the date specified in the title. Otherwise, this market will resolve to "No".
A lawsuit in which Tristan Buckmaster is a named plaintiff, alone or jointly with others, will qualify. An announcement of intent to sue or a legal threat will not qualify; a lawsuit must actually be filed in court.
The primary resolution sources for this market will be official information from the relevant court. However, a consensus of credible reporting may also be used.
