Will Half-Life 3 be announced before 2027?

Updated 5d ago

How to read the numbers

Implied / market-implied YES

The probability of YES implied by current traded prices (mid or last). It is what participants are paying for, not a claim about real-world odds.

Model estimate

A rule-based heuristic from the signal engine when a rule sets one, not a black-box forecast. Some signals only describe liquidity or spreads and may show no model estimate.

Edge / gap

The difference between the model estimate and market-implied, in percentage points (model minus market for YES). Filters may use “largest gap.” This is informational only-not trading advice or guaranteed advantage.

Stance (above / below / near estimate)

Compares market-implied to the model estimate when both exist. Labels are not buy or sell recommendations.

Confidence

A simple UI clarity label for signals (not a prediction). It summarizes the signal’s own magnitude/quality metrics into one of: Low, Mid-low, Mid, Mid-high, or High.

Volume

Reported trading activity for the market, for context on size and liquidity.

Change & sparklines

Movement in market-implied YES over the window labeled on the card-often 24h where data allows.

Signals

Rule-based flags from ingested public data. They are not trade recommendations.

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.

Market summary

What this means

  • This may indicate the market is repricing new information, or reacting to liquidity and order flow.
  • Signals are informational only and not trading advice.
  • BinaryStreaks uses public market data and deterministic, rule-based analysis.
  • Larger gaps can persist when the market is thin, has wide spreads, or is slow to update.
