Episode notes
Prepare For KYC On Prediction Platforms
- Expect prediction platforms to adopt stronger surveillance and KYC in the U.S. to preserve market integrity.
- Matt Walsh and Nic predict Polymarket US will become KYC'd or force offshore users into on-chain anonymity tradeoffs.
OCC Move Could Kill Shared Stablecoin Yield
- OCC rulemaking around GENIUS effectively prohibits stablecoin yield sharing and may bar intermediaries from passing yield to users.
- Matt Walsh explains the OCC presumes payments to holders via third parties violate interest prohibitions, reshaping stablecoin economics.
Brokerages Will Seek Equity If Yield Sharing Is Banned
- If brokerages cannot share yield, they will seek alternative compensation or equity upside from stablecoin issuers.
- Hosts foresee brokerages taking equity, warrants, or issuing their own stablecoins to capture value instead.
