SEC plan to scrap ‘Rule 611’ positive for tokenized US stocks: Galaxy

The U.S. Securities and Exchange Commission has proposed rescinding Rule 611 and Rule 610(e), which currently mandate strict order protection and price quote standards across national market systems. Galaxy head of research Alex Thorn identified this move as a significant catalyst for tokenized U.S. equities, as current regulations effectively prohibit decentralized platforms from operating legally. Under existing rules, automated market makers (AMMs) are unable to comply with trade-through restrictions because they execute orders based on pool prices rather than cross-exchange price matching. Because AMM prices fluctuate constantly, they would inherently violate requirements to guarantee the best available price across all platforms. The SEC intends to replace these rigid mandates with a more flexible best execution framework, potentially accommodating the unique operational structure of blockchain-based trading. This regulatory shift follows the launch of the SEC's Project Crypto in August 2025, which aims to modernize digital asset oversight. If finalized after the 60-day feedback period, this change could remove the primary structural barrier preventing tokenized stocks from trading on decentralized exchanges.
