My Comment to the CFTC's Prediction Market Rulemaking
Michael's response to the CFTC's March 2026 ANPR on prediction markets argues for a multidimensional public-interest framework instead of treating all event contracts identically. Four dimensions: (1) information structure — markets where outcomes emerge from dispersed knowledge (elections, FOMC) enable Hayekian price discovery; concentrated/low-legibility markets (e.g. "what phrase will the CEO say") collapse into pure access trading. (2) manipulation economics — does the contract create incentives to cause the outcome rather than predict it? Cites Brian Armstrong's Oct '25 Coinbase earnings-call mention market and P2P.me trading on its own fundraise. (3) social utility of the price signal — pandemic/climate/election markets serve public decisions; hyperspecific individual-behavior contracts don't. (4) repugnance — Alvin Roth's framework: some markets degrade something morally significant regardless of manipulation (terminally-ill timing markets, nuclear-detonation contracts).
Reframes "insider trading" as three distinct patterns calling for different remedies: outcome influence (fix via market design, not surveillance), duty breach (the Polymarket Maduro-strike case — misappropriation framework applies), and information advantage without breach (the price-discovery engine — restricting it would erode what the CEA was written to protect).
Third argument: resolution integrity is load-bearing. Event contracts have no external reference price. Three failure modes: rule mutability after listing (Polymarket's '24 government-shutdown contract — resolution language added Dec 20, odds spiked 20%→98%, no shutdown actually occurred), undefined rule hierarchy (Venezuela election overridden via UMA vote despite "primary source" language), single-source oracle vulnerability (Paris-CDG temperature sensor, suspected hairdryer attack, ~$34K in payouts). Whenever resolvers can also hold positions, the incentive to influence resolution is structural. Recommends: original specs as complete reference document, fixed resolution-source hierarchy at certification, cost-of-corruption assessment for single-signal markets.
