UNVEILING THE PREDICTION MARKET FOREST

Summary from the TLDR Crypto newsletter

Onchain order-book data from Polymarket between April 2024 and April 2025 reveals persistent pricing inefficiencies. Leveraging heuristics and LLM-assisted semantic matching, this research classifies mispricings into intra-market “Market Rebalancing” and cross-market “Combinatorial” arbitrage, scanning 17,218 conditions. Opportunities surfaced in 7,051 single-condition and 662 multi-condition markets, with 11 logically linked market pairs enabling cross-market trades. Onchain activity shows arbitrageurs have already extracted about $40 million, highlighting both the scale of inefficiency and the corrective role of sophisticated traders in decentralized prediction markets.
