Resolution criteria on PolyGram: This market will resolve to if Valve publicly and explicitly announces that a new Half-Life game is in production by the specified date, 11:59 PM ET. Otherwise, this market will resolve to "No". To qualify for a "Yes" resolution, the game must be explicitly acknowledged by Valve to be an installment of the Half-Life franchise or have the words "Half-Life" in the title. Updates to and expansion packs for already-released games will not be sufficient to resolve this market to "Yes". An announcement by Valve of a new qualifying game before this market's end date will immediately resolve this market to "Yes", regardless of when the announced game becomes available to the public.
PolyGram is an on-chain prediction market where you trade YES or NO outcome shares with real USDC on Polygon. For this market, buy YES if you believe the event will happen, or NO if you think it won't. Your maximum loss is your stake — winning shares pay $1.00 each at resolution. Unlike sportsbooks, there is no house edge: prices are set by supply and demand from other traders and reflect the crowd's real-time probability.
Market outcomes
| March 31, 2026 | 0% YES | 100% NO |

Valve has not released a mainline Half-Life game since Half-Life 2: Episode Two in 2007. The market resolves affirmatively only if Valve makes an explicit public announcement that a new Half-Life game is in production before 30 June 2026—a window of approximately 18 months from the market's creation. The announcement must either identify the project as a Half-Life franchise instalment or include "Half-Life" in the title; spin-offs, remakes of existing titles, or expansion packs do not qualify.
The 0% implied probability reflects Valve's demonstrated reluctance to greenlight new Half-Life projects despite sustained fan demand. Half-Life: Alyx, released in March 2020, was a VR prequel rather than a direct sequel, and Valve has issued no substantive updates on future Half-Life development since. The company's recent output has prioritised Steam platform development, Counter-Strike 2, and Dota 2 maintenance over narrative-driven single-player releases. This historical pattern—combined with Valve's flat organisational structure and selective project greenlight process—establishes the baseline for current market pricing.
Traders should monitor Valve's official announcements, Steam news channels, and major gaming conferences including The Game Awards and Summer Game Fest, where significant publisher reveals typically occur. Any statement from Valve leadership regarding Half-Life development, even in preliminary form, would constitute a catalyst. The settlement window's mid-2026 endpoint creates a defined timeframe; no announcement by that date triggers automatic resolution to "No."
Resolution is handled by the UMA optimistic oracle on Polygon. A proposer submits the outcome, a two-hour dispute window opens, and if no one stakes a counter-claim the payout is final. Contested outcomes escalate to UMA token-holder voting. Payouts clear in USDC to the winning side.
The mechanics for trading "New Half-Life game by...?" are the same as any other PolyGram event contract. Each YES share resolves to $1 if the event happens, or $0 if it doesn't. The current price between 0¢ and 100¢ is the market's probability estimate, set live by the order book.
$16K in lifetime turnover and $1K of resting liquidity puts this market in the below the median by volume for pop culture contracts on PolyGram. Order-book depth is thin — large orders may need to be split across the book or executed as limit orders.
The market has been open for 6 months — the price has had time to stabilise as new information arrived.
Higher-volume markets tend to have tighter spreads and faster price discovery — meaning the displayed YES/NO percentages are more likely to reflect the true crowd-implied probability rather than a single trader's directional view.
Resolution is handled by the UMA optimistic oracle on Polygon. A proposer submits the outcome, a 2-hour dispute window opens, and if uncontested the payout is final. Contested outcomes escalate to UMA token holders.
This prediction market is scheduled to close on 30 June 2026. After the resolving event occurs, settlement typically clears within 24 hours once the UMA optimistic oracle confirms the outcome. All payouts are in USDC on the Polygon network.

Prediction-market positions can lose 100% of staked capital. Outcomes are uncertain by definition — historical accuracy of crowd-implied probabilities is high in aggregate but not for any single market. PolyGram does not provide investment advice. Trade only with capital you can afford to lose.
Regulatory status varies by jurisdiction. Germany, the United States, and most EU countries treat Polymarket-style event contracts under one of three frameworks: financial derivative, gambling product, or unregulated novel asset. Consult local counsel before trading.
