Under a September 17 conditional exemption from the Securities and Exchange Commission (SEC), venues offering permissioned automated market maker (AMM) pools for tokenized National Market System (NMS) stocks can operate without key Regulation NMS protections, even while guaranteeing standard shareholder rights.
Shareholder Rights vs. Execution Protections
The SEC order grants temporary relief from exchange and alternative trading system (ATS) definitions for trading venues facilitating approved transactions in eligible tokenized NMS stocks. Tokenized shares must preserve identical rights to traditional equity classes, including voting rights, dividend entitlements, and claims on residual assets upon liquidation. However, third-party synthetic exposure, security-based swaps, rights, and warrants are strictly excluded from the relief.
Despite preserving ownership rights, exempt venues operate outside key Regulation NMS rules, such as Rule 611 trade-through protections that prevent trades at prices worse than protected quotations on other venues. Nevertheless, FINRA member brokers retain their Rule 5310 best-execution duties when handling covered customer orders, and venues must post machine-readable dollar transaction data updated within 10 minutes of each trade. This regulatory framework builds on ongoing market trends surrounding trading tokenized equities across digital platforms.
Oracle Reliance and Market Data Requests
To address how trading venues evaluate external price data, market-data provider Douro Labs—a contributor to Pyth Network and operator of Pyth Pro—submitted a request to SEC staff on October 9. The submission urged regulators to establish provider-neutral principles for assessing external price feeds and oracles, emphasizing independent data contributors, manipulation-resistant aggregation, and benchmark comparisons.
Recent regulatory filings demonstrate how different venues utilize external market data:
- OKXICE (October 4 notice): Sets execution prices via pool asset ratios while using Massive.com for stock prices and halt data, affiliated OKX INC for stablecoin indices, and Circle's USDC as a payment asset.
- TSV LLC (September 23 notice): Noted that operations had not yet commenced and listed prospective external data uses while confirming a production market-data provider had not been selected.
- Data Mandates: Venues must publish free, machine-readable dollar-denominated transaction data for the preceding 30 days, refreshed within 10 minutes of execution.
This oversight aligns with broader institutional shifts, such as recent SEC listing approvals for complex financial instruments.
Why It Matters
This conditional exemption represents an attempt by regulators to allow automated market maker mechanics into equity trading without forcing decentralized venues into traditional exchange frameworks. By excluding Rule 611 protections, the SEC shifts the primary responsibility for price protection onto broker best-execution obligations and venue transparency disclosures. As tokenization expands, standardized oracle benchmark criteria will become vital to prevent pricing disparities across isolated trading pools.
