A trader who ran ~10,000 automated trades through Polymarket dissects why most prediction market terminals fail: execution mirages, non-synthesizing research layers, and strategy tabs that are deck screenshots disguised as features. Lays out the baseline infrastructure real traders need and argues only two terminal types survive the next 24 months: institutional API rails and a trader-native terminal built by someone who has actually lived the workflow.

Survey of recent research on why conventional market making fails in prediction markets. Covers cross-venue fragmentation (the same contract at 58-67 cents on different platforms), the January 2026 Polymarket XRP exploit that paid $231K on thin weekend liquidity, Kalshi's structural longshot bias, and evidence from 150M Polymarket trades that the top 5% skilled traders earned $228M while spread capture barely moves P&L. Concludes passive LPs on these venues behave more like underwriters of terminal risk than classical market makers.

Data-driven analysis benchmarking Kalshi's sports markets against traditional sportsbooks. Kalshi's monthly volume grew 80x to $14.4B in March 2026, with NCAA March Madness generating $3.3B in notional volume comparable to total US wagered on the tournament. In-game prices correlate at 0.99+ with FanDuel, but Kalshi's taker fees (up to 3.5% at midpoint) and thinner in-game liquidity (76% depth decline vs pre-game) currently limit institutional execution. Includes a valuation comparison showing Kalshi priced as an exchange ($20B) vs sportsbooks trading at 2-4x revenue.

Identifies five MEV-style edges on Polymarket that most retail traders are unaware of: oracle latency arbitrage (trading on news before UMA oracle updates), resolution arbitrage (front-running outcome settlement), dispute sniping (gaming the UMA dispute process), orderbook imbalance exploitation, and conditional probability arbitrage across correlated markets. Frames Polymarket as a 'hidden MEV playground' where sophisticated actors extract value from structural inefficiencies rather than informational edges.

Argues prediction markets are evolving a second layer analogous to derivatives built on stock exchanges. Covers three hedging use cases: crypto risk hedging via binary price markets, attention markets (Trendle) as sentiment hedges against binary positions, and cross-platform hedging enabled by DeFi composability (Gondor lending against PM positions, DFlow tokenizing Kalshi contracts as SPL tokens). Identifies liquidity fragmentation, execution risk, and UX as barriers to mainstream hedging adoption.

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.

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.
