Polymarket, Kalshi, CFTC battles, op-sec incidents, and the maturation of event-based crypto markets. The state of on-chain prediction at the edge of finance and politics.
Prediction markets graduated from crypto-curiosity to mainstream news venue in the 2024 US election cycle and have only grown since. This cluster covers the category in depth: Polymarket's volume trajectory and Nasdaq listing path, Kalshi's CFTC-regulated counter-positioning, the recurring state-level bans (Minnesota, etc.) and the federal preemption fight, and the operational security failures that periodically remind the industry it is still early.
We treat prediction markets seriously because their information value is real. A 73 percent probability on a Polymarket contract aggregates more information about a future event than most newsrooms can match. The cluster covers how those probabilities form (liquidity, market depth, manipulation resistance), how they fail (low-liquidity manipulation, resolution disputes, oracle dependency), and how they compare to traditional polling and odds-making across politics, sports, and crypto-native events.
Recurring threads: Polymarket vs Kalshi market share, the CFTC's evolving stance on event contracts, state vs federal jurisdiction over prediction markets, op-sec incidents (key compromises, signer issues), and the broader question of whether event-based markets become a third major retail product category alongside spot trading and perp trading. The cluster is the panda's working map of a sector still figuring out what it is.
