ArXiv study flagged on pricing gaps between prediction markets and options
An ArXiv study is circulating on social media examining why identical event contracts trade at different prices in prediction markets versus options venues. A July 16 Cryptodaily post by Idris Calloway flagged the research, though neither source provides methodology, specific price examples, or substantive analysis. The study itself is not reproduced in available coverage. The discussion arrives as prediction market pricing mechanics draw growing scrutiny from traders, academics, and regulators.
The pricing-gap question lands at a tense moment for platform credibility. Polymarket and Kalshi are racing to prove their markets price events as efficiently as traditional derivatives, because any persistent wedge feeds the gambling critique that Michael Burry and Senate bill sponsors have amplified. If identical contracts systematically cheapen on prediction markets versus options, that gap becomes evidence that these venues attract irrational retail flow rather than informed capital.
Professional desks at DRW, Wintermute, and IMC care directly: their market-making models assume near-arbitrage efficiency, and a structural mispricing would force them to quote wider or pull back. The study is thinly reported so far, but its mere existence gives both defenders and critics a new empirical battlefield.
