An annual forecasting tradition
What started as Scott Alexander publishing annual predictions on Slate Star Codex and later Astral Codex Ten has evolved into a vibrant forecasting community tradition. This contest offers both seasoned and aspiring forecasters a chance to refine their skills while tracking current events through a predictive lens. For 2025, Scott Alexander has once again partnered with Metaculus to host the competition.
