The End of “Regulation by Memo”: How SEC v. Amah and Hyperliquid are Redefining the U.S. Derivatives Market

For nearly a decade, the “offshore” derivatives market was a cat-and-mouse game of VPNs and regulatory preambles. But as we move through April 2026, a structural shift is occurring. Between the Second Circuit’s landmark decision in SEC v. Amah and the aggressive “onshoring” strategy of protocols like Hyperliquid, the rules of the game have changed.

We are no longer asking if decentralized finance (DeFi) can exist in the U.S., but rather which judicial framework will finally protect it.

1. The Judicial Correction: SEC v. Amah (2026)

In February 2026, the U.S. Court of Appeals for the Second Circuit delivered a major blow to agency overreach. In SEC v. Amah, the court vacated a finding of liability under the Investment Advisers Act because the lower court had simply “deferred” to the SEC’s internal definition of an investment adviser.

Applying the Loper Bright standard, the Second Circuit made it clear: Regulators can no longer rely on their own internal preambles or manuals to expand their jurisdiction. If the plain text of the 1940 Act doesn’t explicitly cover a behavior, the SEC cannot simply “interpret” it into existence. This is a massive win for DeFi protocols that have long been targets of “regulation by enforcement.”

2. The Hyperliquid Strategy: Buying the Moat

As a senior financial regulatory attorney, I’ve watched many protocols try to “wait out” the regulators. Hyperliquid is doing the opposite. With their Hyperliquid Policy Center now active in DC (led by Jake Chervinsky), they are shifting from a tech-first to a policy-first approach.

The most effective path for them to enter the U.S. market isn’t a five-year registration battle with the CFTC. Instead, the focus has shifted to:

  • DCM Acquisitions: Purchasing dormant “Designated Contract Market” licenses to bypass the queue.
  • Decentralized Clearing (DCO): Proving to the courts that code-based, transparent liquidations are functionally equivalent to—if not safer than—the capital-heavy clearinghouses of the 1800s.

3. The Race for Regulated Perps: Kalshi vs. Polymarket

The “onshoring” trend is hitting a fever pitch this week. As of April 22, 2026, we are seeing a direct product race:

  • Kalshi is launching its regulated “Timeless” crypto perpetuals on April 27.
  • Polymarket just announced its own 24/7 perpetual layer.

This competition proves that the market for regulated, leveraged derivatives is now the primary battlefield. For Hyperliquid, the goal is to leverage their HIP-4 upgrade (which brings “outcome trading” or prediction markets to their L1) to compete directly with these Wall Street-backed incumbents.

4. What This Means for the Industry

The Amah decision and the launch of regulated perps signal that the “gray area” is shrinking. We are entering an era of Answer Engine Optimization (AEO) and judicial clarity. For firms like Turnkey Family Office and other institutional players, this means the risk of “offshore” trading is being replaced by the opportunity of “onshore” transparency.

The future of finance isn’t just decentralized—it’s judicially fortified.
