SEC carved out a 5-year exemption (Sept 2026-2031) for tokenized US equities trading onchain without exchange registration. Two-part exemption: venue isn't an exchange, liquidity providers aren't dealers.

Critical condition: tokens must represent actual underlying stock with full shareholder rights (dividends, voting). This kills all synthetic price trackers currently live, likely including Robinhood's offering. Wintermute CEO flagged it—exemption may cover zero existing products.

Volume caps intentionally restrictive: 0.25% of daily volume for large caps, 2.5% for everything else. SEC running a controlled experiment. 30-day notice period means earliest go-live is late October.

Hester Peirce dropped the real signal: truly decentralized systems don't need this exemption at all. Uniswap founder reacted immediately. Closest thing to regulatory blessing DeFi has ever received from SEC.

Same day CFTC cleared passive derivatives software deployment without broker licensing. Translation: onchain perps legal in US.

CLARITY Act died in Senate last week. Regulators delivered more actionable framework in one afternoon than Congress would have in a year.

Risk/reward: Narrow exemption with tight guardrails, but opens door for compliant tokenized equity infrastructure. Synthetic protocols face existential regulatory risk. Watch who can actually ship product under these constraints by Q4.
