Sportsbooks vs Prediction Markets - Market Structure and Its Effects
taetaehoho·May 12, 2026·II·Microstructure

Compares spreads across DraftKings, FanDuel, Polymarket, and Kalshi on identical sports markets to isolate how counterparty identification versus maker competition affects pricing.

Momin·Apr 21, 2026·II·Commentary

Skeptical counter to the democratizing-finance framing around prediction markets. Cites Polymarket data showing 70% of 1.7 million addresses lost money and that the top 0.04% captured over 70% of the $3.7B in realized profits, and argues the structure predictably funnels retail into informed counterparties (including platform-operated market-making desks at Kalshi and Crypto.com).

sybilpm·Mar 8, 2026·II·Microstructure

Uses the case of a trader sniping Polymarket's geopolitical strike markets at 10 cents to argue that continuous order books are structurally broken for binary assets. In traditional markets, sniping costs basis points; in prediction markets, it costs 80 cents on the dollar because prices jump from 0.10 to 0.99 on a single tweet. Proposes frequent batch auctions (citing Budish, Cramton, and Shim) to shift competition from speed to price accuracy, and introduces the concept of a 'liquidity mirage' where the highest social-value markets are precisely those where passive liquidity is unsustainable.
