KYC/AML on Polymarket for larger positions?

Been watching some of the larger markets on Polymarket, especially around political outcomes or significant economic events, and I'm curious about the compliance side for bigger plays. For users betting, say, five or six figures, what kind of KYC/AML protocols are in place? Does Polymarket have different tiers of verification, or is it a blanket system? I'm thinking specifically about how they manage potential red flags for money laundering or even just large-scale capital movement across jurisdictions, given the nature of prediction markets and the inherent cross-border access. It seems like a complex area to navigate while still maintaining the platform's accessibility and speed. Anyone have insights into their operational strategy here, or even just general thoughts on how platforms like this balance regulatory demands with user experience?
