US crypto market structure: what investors need to know

Crypto market structure refers to the full ecosystem of participants, platforms, rules, and infrastructure that make digital asset markets function — exchanges, brokers, custodians, market makers, token issuers, and regulators all included. Unlike traditional finance, where the regulatory framework was cemented decades ago, the rules governing crypto are still being written, making market structure one of the defining policy debates in Washington.

Why it matters

The architecture of a market determines how well it protects retail investors, how transparently prices are set, and whether large institutions can participate at scale. The 2022 collapse of FTX illustrated the cost of structural gaps: customer assets held by a centralized exchange with inadequate oversight vanished almost overnight. Centralized exchanges like Coinbase and Binance hold customer assets directly, while decentralized platforms like Uniswap operate through smart contracts with no custodial role — each model carries distinct regulatory implications.

In March 2026, the SEC and CFTC issued joint guidance categorizing crypto assets into five groups. Bitcoin, Ethereum, and XRP were designated digital commodities, a classification that shifts primary oversight toward the CFTC rather than the SEC.

Market impact

The Digital Asset Market Clarity Act — the CLARITY Act — aims to codify that framework into federal law, defining digital commodities and placing their trading under CFTC jurisdiction. As of May 14, 2026, the bill has cleared the House and is advancing in the Senate but has not yet been enacted. Passage would accelerate institutional adoption by giving hedge funds, pension funds, and custodians the regulatory certainty they require to deploy capital at scale.
