Market Impact Snapshot
Dismantling Rule 611 shifts the compliance burden from rigid per-trade price matching to flexible 'best execution' standards, structurally enabling institutional AMM trading for the first time.
Expected 7-day move · by coin
Ethereum remains the primary settlement layer for institutional tokenization pilots, though immediate price moves will be constrained by the long regulatory timeline.
Solana's high speed and low latency make it a prime candidate for fast-execution AMMs, but regulatory clarity is still distant.
As the leading AMM protocol, Uniswap stands to benefit directly if on-chain equity trading is permitted, though volume increases are long-term.
Sentiment: Positive but long-term structural
Liquidity: medium
Our conviction: 75/100 — an estimate, not a guarantee.

Executive summary
On June 11, 2026, the Securities and Exchange Commission (SEC) submitted a proposal to rescind Rule 611 and Rule 610(e) of Regulation NMS, according to a report by CryptoSlate. These two decades-old rules govern trade-throughs and locked quotes, forcing traditional brokers to execute stock trades at the National Best Bid and Offer (NBBO) across protected venues. While designed to protect retail investors from inferior execution, this framework has acted as a structural barrier to automated market makers (AMMs) and decentralized finance (DeFi) platforms.
AMMs price assets through liquidity pools and bonding curves rather than order books, making it mathematically and operationally impossible to comply with Rule 611's rigid routing requirements. Rule 610(e) raises a related issue, as AMM price drift can cause on-chain prices to lock or cross the displayed NBBO. The SEC's proposal, championed by Chairman Paul Atkins, aims to simplify market structure, reduce transaction costs, and foster technological innovation. If finalized, this shift could pave the way for institutional trading of tokenized equities on public or permissioned blockchains.
Why it matters
The primary impact of this regulatory shift is structural rather than immediate. Historically, regulatory announcements of this scale do not immediately translate into spot trading volume spikes, as the rulemaking process involves extensive public comment periods. However, the removal of Rule 611 fundamentally alters the market structure for real-world asset (RWA) tokenization.
From a capital flows perspective, traditional financial institutions have avoided deploying capital into AMM-based equity pools due to the legal liability of violating trade-through rules. Rescinding the rule shifts the compliance standard to "best execution." Under a best-execution framework, broker-dealers can evaluate the execution quality of an AMM over time, taking into account liquidity depth and slippage, rather than requiring per-trade price matching. This is highly compatible with blockchain architecture and could unlock substantial institutional capital flows into DeFi protocols.
While speculative assets often experience sharp price moves on low trading volume during regulatory rumors, sustainable institutional adoption of tokenized equities will require deep, consistent trading volume in permissioned pools to prove the viability of the AMM model to traditional regulators. The primary beneficiaries of this change will be high-throughput layer-1 blockchains and established AMM protocols capable of hosting permissioned liquidity pools. However, market participants should note that tokenized equities still face significant unresolved hurdles, including securities registration, custody requirements, and investor-rights frameworks. Furthermore, traditional stock exchanges like the NYSE and Nasdaq may lobby heavily against the proposal to protect their execution monopolies, which could lead to prolonged legal battles and suppress immediate trading volume growth.
What it means for you
The likely scenarios — and the practical takeaway.
In a bullish scenario, the rapid rescission of Rule 611 is met with immediate regulatory clarity regarding security registration and custody. Major Wall Street institutions quickly deploy permissioned liquidity pools on public networks like Ethereum and Solana, driving a substantial increase in on-chain trading volume. This influx of institutional capital validates the AMM model for traditional equities, leading to a re-rating of DeFi blue-chip tokens. As trading volume migrates on-chain, transaction fees generate significant yield for protocol participants, driving sustained upward price moves.
The most likely outcome is a slow, highly regulated transition toward hybrid TradFi-DeFi market structures, carrying a 55% probability. The SEC under Chairman Paul Atkins is expected to successfully rescind Rule 611, but the agency will likely pair this change with a strict "innovation exemption" framework. This framework, previously discussed by Commissioner Hester Peirce, will likely mandate volume limits, whitelisting (KYC/AML), and permissioned environments for early participants. Consequently, we will not see an immediate migration of public equities to public AMMs. Instead, major investment banks and asset managers will launch pilot programs on institutional subnets or permissioned EVM chains. Speculative RWA tokens may experience short-term price moves, but these will likely occur on thin trading volume and lack fundamental support. Genuine utility and trading volume will concentrate on established layer-1 networks like Ethereum and Solana that can support permissioned compliance layers. Traditional exchanges will likely mount a vigorous lobbying campaign during the comment period, which will drag out the implementation timeline. This regulatory lag will prevent immediate retail access to tokenized stocks on public DeFi platforms, keeping the immediate market impact on public token valuations muted.
In a bearish scenario, intense lobbying from traditional exchanges like the NYSE and Nasdaq successfully stalls or guts the SEC's proposal. Even if the rule is rescinded, the SEC fails to provide a viable path for security registration, leaving tokenized stocks in a regulatory gray area. Institutional interest evaporates as legal departments refuse to clear the compliance risks associated with public blockchain settlement. Speculative RWA tokens suffer sharp downward price moves on declining trading volume as the market realizes the structural integration is years away.
Your takeaway
Position in high-throughput layer-1s and institutional-focused DeFi protocols (such as Ethereum, Solana, and Uniswap) that are prime candidates for permissioned RWA deployment, while avoiding speculative, non-compliant RWA wrappers.

Bottom line
The most likely outcome is a multi-year transition where the SEC rescinds Rule 611 and introduces 'innovation exemptions' for permissioned on-chain trading, carrying a 55% probability. The single biggest risk is pushback and litigation from traditional exchanges (NYSE/Nasdaq) seeking to protect their market share, which could delay implementation. Traders should watch for the close of the SEC public comment period and any draft frameworks for the proposed 'innovation exemptions' to gauge the timeline of institutional adoption.
