Kalshi and Polymarket Diverge on Resolution and Withdrawal Rules

The headline takeaway is less about who is faster than about how resolution design shapes the user experience after a market settles. Kalshi's exchange review and Polymarket's oracle challenge model create different exposure to disputes and delays, which matters most for traders who treat prediction markets as a venue for capital rather than entertainment. For market structure watchers, the open question is whether these procedural differences become a competitive factor as the platforms scale, or whether users simply price them in as a cost of doing business on each venue.
