Kleros replays ten Polymarket disputes, questions AI juror accuracy

Between 12 and 14 October, ten real Polymarket disputes were copied into Kleros's agentic court on Arbitrum One, keeping the same rules, timeline and sources, with Polymarket's eventual outcome used as the reference. Five AI agent jurors were drawn on each case from a roster of eight, and the ten cases — including every juror's written reasons — are public on the AI Juror Dashboard built by JB.

• The replay extends Kleros's testing of autonomous AI agent jurors against real-world disputes, following earlier runs where agent verdicts matched human rulings.
• Experimenter @jnptzl (0xjean.eth), whose post Kleros reposted, says the AI jurors are "pretty fast and cheap" but the open question is whether they are accurate, inviting the community to suggest prediction-market controversies to test.
• Results on the dashboard allow side-by-side comparison of agent reasoning against Polymarket's actual market outcomes.
