Prediction Markets and Implied Correlation
Jon Turek·Mar 24, 2026·II·Microstructure

Introduces implied correlation as a trading opportunity in prediction markets. Polymarket currently prices a 60%+ chance of 5% unemployment this year alongside only a 10% chance of aggressive Fed rate cuts, even though every historical episode of that unemployment spike triggered an average of seven cuts. Argues that because prediction markets are still priced idiosyncratically, cross-market mispricings like this are common and create attractive relative value trades.

Turning Probability into Assets: A Look Ahead at Prediction Market Agents
Jacob Zhao·Mar 5, 2026·III·Design

Comprehensive research report on AI agents for prediction markets, proposing a four-layer architecture (data, analysis, execution, learning) for autonomous trading systems. Maps the ecosystem of existing agents, compares Kelly criterion vs fixed-fraction bet sizing, surveys arbitrage strategies across platforms, and outlines business models (agent-as-a-service, liquidity mining, data sales). Argues that AI agents will become the dominant market participants within two years, transforming prediction markets from retail-driven speculation into infrastructure for probabilistic information.

Why Prediction Markets Aren't Gambling? (The Math)
Roan·Feb 9, 2026·II·Microstructure

Provides a quantitative framework for distinguishing gambling from systematic trading on prediction markets, including a five-point diagnostic and three trader archetypes classified by profitability. Explains why Polymarket's CLOB creates renewable structural arbitrage by design, and covers Kelly position sizing, adverse selection measurement via fill quality, and probability term structure as tools for building a repeatable edge.

All Types of Arbitrage on Prediction Markets
Nekt0·Feb 5, 2026·I·Microstructure

Catalogs eight distinct arbitrage strategies available on prediction markets: classic YES+NO mispricing, cross-platform, range, conditional, time, hedged, resolution, and orderflow arbitrage. Each type includes concrete examples with dollar amounts and specific risk factors to watch for.

The Perils of Election Prediction Markets
John Sides·Dec 18, 2025·II·Commentary

Examines Clinton and Huang's research on 2024 election market accuracy, finding PredictIt at 93%, Kalshi at 78%, and Polymarket at 67%, while also documenting significant cross-platform price divergences for identical contracts near Election Day. Raises concerns about Kalshi's media partnerships with CNN and CNBC, arguing they create incentives for sensational coverage of market movements and potential manipulation of thin markets.

Prediction Markets: The Next Level
keshav·Sep 23, 2025·II·Design

Proposes a DeFi primitive for borrowing against prediction market positions, arguing that collateralization solves the capital lock-up problem in long-dated markets. Walks through how position lending could improve liquidity, correct persistent mispricings like longshot mispricing, and open composability with the broader financial ecosystem, while flagging the liquidation risks unique to binary outcomes.

Meta Pool: A Unified Infrastructure for Liquidity and Resolution Trust in Prediction Markets
Jeff Opinion·Aug 19, 2025·III·Design

Proposes Meta Pool, a cross-chain infrastructure to unify prediction market liquidity across fragmented platforms. Introduces resolution-aware meta-pools for swapping semantically similar tokens with different oracles, CredibilityTokens for trading oracle trustworthiness, and ConvergenceTokens for hedging divergence risk. Estimates $3.4-8.5M in annual efficiency losses from current fragmentation.

Unravelling the Probabilistic Forest: Arbitrage in Prediction Markets
Oriol Saguillo, Vahid Ghafouri, Lucianna Kiffer, Guillermo Suarez-Tangil·Aug 5, 2025·III·Microstructure

Examines mispricing inefficiencies on Polymarket, identifying two categories of arbitrage opportunities: those within single markets and those spanning multiple related markets. Using blockchain transaction analysis, the researchers estimate approximately $40 million in profits were extracted through exploitation of these pricing inconsistencies.

The Risk Behind Arbitrage in Prediction Markets
michaellwy·May 23, 2025·II·Microstructure

Explains why apparent arbitrage opportunities between Polymarket and Kalshi often aren't risk-free. Different rule definitions, resolution criteria, and oracle systems mean seemingly identical markets can resolve differently. Argues prediction markets are fundamentally non-fungible due to differing referee systems, leading to permanent landscape fragmentation.
