Can AI Beat the Prediction Market? (I Ran a Simulation)

Peer-to-peer betting platforms where users buy shares on real-world outcomes (2:15). Unlike sports gambling against the house, these markets aggregate collective intelligence through financial incentives, with share prices reflecting probability (e.g., 70 cents = 70% likelihood). When money is on the line, people bet on what they truly believe will happen.

Prediction markets combine collective private information into a single price point (3:30). They cut through noise because 'talk is cheap' but money reveals truth - smart money quickly corrects mispriced predictions. Research shows markets predicted scientific replication outcomes with 73% accuracy, outperforming even the researchers themselves (4:15).

The Forecast Bench study found top 2% human 'super forecasters' achieved 68% of perfect accuracy, while the best LLMs at the time reached only 60% (5:00). This established a benchmark that the video's experiment aimed to challenge with newer models.

The experiment used Claude Code to create a system with three specialized skills (6:15): data collection from Polymarket, isolated prediction sub-agents, and evaluation/visualization. Each of 100 questions was answered by an individual agent with no shared context.
