USDC Bridge / Redemption Spread Arbitrage

A near-certain Polymarket share is guaranteed to redeem for $1 once the market settles, but settlement and moving cash off Polygon takes time. Some holders sell those shares below $1 just to get their money out instantly. This strategy buys from those impatient sellers and waits for the guaranteed $1 redemption. The edge is that people pay a premium for instant liquidity, and the cost of bridging funds off-chain is asymmetric.

What you need to run it

Monitor of near-certain markets trading at a redemption discount
Bridge/withdrawal cost + timing model (Polygon to L1/exchanges)
Capital willing to hold to UMA finalization
