Will Half-Life 3 be announced before 2027?
What resolves this contract
This market will resolve to "Yes" if Valve publicly and explicitly announces that Half-Life 3 is in production by December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No". The announcement of the creation of any expansion or sequel not explicitly named "Half-Life 3" (e.g., Half-Life: Alyx, Half-Life 2: Episode One) will not be sufficient to qualify this market toward a "Yes" resolution. The game must have the words "Half-Life 3" in the title to qualify. The resolution source for this market will be official information from Valve or a consensus of credible sources.
How to read the price
Prediction market prices are expressed in cents on the dollar. A YES contract trading at 55¢ means the market is pricing in a 55.5% implied probability of the event resolving YES. If resolution comes back YES, the contract pays $1. If NO, it pays $0.
Volume vs. open interest
Total traded volume ($99,196) reflects every buy and sell across the life of this contract. Open interest ($6,655) is the dollar value of positions currently held by traders. Deep liquidity and wide open interest are the two signals that the quoted price is reliable.
