Market Volatility & The Trust Playbook: Navigating Fraud in Two-Sided Marketplaces

Mark Porteous, who built StockX's fraud program from the ground up, joins Karisse to break down why two-sided marketplaces are so much harder to protect than standard e-commerce. The focus is market volatility: when a sports result or viral drop swings prices overnight, sellers walk away from deals and buyers file chargebacks to rebuy at the bottom. They cover why models and vendors can't run on autopilot through those swings, and how to build a playbook before the next spike hits.
