Three Paths of CEX US Stock Products
Crypto exchanges (CEXs) offer US stock trading products that do not grant direct ownership of American equities. Instead, they achieve exposure through three distinct routes: traditional API broker integration, tokenized synthetic assets, and perpetual contracts. Among these, the tokenized model is the most complex, delivering only synthetic price exposure rather than actual shares. Users receive claims on a basket of underlying assets, not the stocks themselves.
The Five-Layer Tokenized Architecture and Vaporized Rights
In the tokenized model, the journey from US stock to user account passes through five structural layers: (1) underlying US stock custody; (2) clearing and settlement; (3) token issuance by a centralized entity; (4) liquidity aggregation across platforms; and (5) end-user trading on CEX. At each layer, costs, time delays, and structural leverage are introduced. The result: voting rights evaporate entirely, dividends become contractual promises rather than direct distributions, and the SIPC insurance protection (which covers direct US stock holdings) becomes completely inapplicable. Users rely solely on the commercial credit of the token issuer.
Alpaca's 94% Clearing Monopoly: A Critical Single Point of Failure
Alpaca acts as the dominant clearing and custodian for US stock products on major CEXs, commanding approximately 94% of the market. This near-total monopoly creates a systemic liquidity bottleneck: any technical outage, regulatory action, or financial distress at Alpaca would simultaneously halt or impair all dependent products. Moreover, the risk transfer mechanism is absent. When the underlying US stocks experience extreme volatility, forced liquidations are executed solely under Alpaca's order book and margin rules, leaving users exposed to unpredictable slippage and loss prioritization.
Investors trading US stock products on CEXs must recognize they are not purchasing real equity, but heavily intermediated derivative instruments with a risk profile fundamentally different from traditional US stocks.
