Wall Street’s push toward round-the-clock trading has moved from concept to a concrete market structure experiment. OKXICE, the 50-50 venture between crypto exchange OKX and Intercontinental Exchange, has published a notice outlining a U.S. venue for tokenized stocks that would operate 24 hours a day, seven days a week under the Securities and Exchange Commission’s new temporary exemption.
The proposed venue would initially make 63 U.S.-listed stocks available, including Apple, Nvidia, Microsoft, Tesla, JPMorgan Chase and Coinbase. Trading would take place on permissioned Uniswap v4 liquidity pools deployed on OKX’s XLayer blockchain, with each token paired against USDC, USDG or USDT. The structure is a significant departure from a conventional exchange: there would be no order book, no margin and no central clearing agency. Trades would be fully funded and settle atomically, with both assets transferring in the same blockchain transaction.
That design shows what tokenization can change and what it cannot. Extending trading beyond exchange hours and settling immediately could give investors greater flexibility while reducing the time between execution and final transfer. But a digital wrapper does not remove the need for custody, shareholder rights or compliance. Under OKXICE’s model, an outside tokenizer acting through an SEC-registered, FINRA-member broker-dealer would hold one underlying share for every token outstanding. The tokens are intended to carry the same dividends, voting rights and liquidation claims as the equivalent traditional shares.
Access would also remain tightly controlled. Investors would have to pass identity, anti-money-laundering and sanctions checks, open an account with the tokenizer and use an approved self-custodial wallet. A non-transferable token in that wallet would confirm eligibility before every trade or liquidity action. In other words, this is permissioned onchain finance, not anonymous stock trading.
The plan follows the SEC’s September 17 “Innovation Exemption,” a five-year framework that conditionally allows tokenized National Market System stocks to trade through automated market makers. The exemption limits symbols and volume, requires token holders to receive equivalent shareholder rights, and gives issuers an opportunity to object when an unaffiliated third party tokenizes their shares. OKXICE’s notice says Cerebras Systems has already objected, and Cerebras does not appear on the proposed list.
The most important test will be market quality outside regular exchange hours. OKXICE’s smart contracts would price trades from the ratio of assets in each liquidity pool, not from the underlying stock market. The venue itself warns that token prices could diverge from the ordinary shares when exchanges are closed, liquidity is thin or trading is halted. Liquidity providers would not necessarily be registered broker-dealers, could withdraw at any time and would have no general obligation to keep quoting. Large trades could therefore move prices sharply or fail altogether.
Those limits make the project less a replacement for established exchanges than a controlled test of whether blockchain-based trading can preserve the protections investors expect from public equities. The SEC caps trading in the most liquid Tier 1 names at 0.25% of the underlying stock’s prior-month average daily volume and allows no more than 75 such symbols on a venue. It also requires trading to stop when the underlying share is halted on its primary exchange. OKXICE says its activities under the exemption are not registered with the SEC, and the venue is not subject to Regulation NMS, although its use of the exemption remains under SEC oversight.
For ICE, owner of the New York Stock Exchange, the venture offers a way to participate in tokenization without waiting for the conventional market day to be rebuilt around blockchain rails. For OKX, it offers a route from offshore products that provide economic exposure toward a U.S. structure designed to convey actual shareholder rights. Yet the commercial question remains unresolved: whether investors will accept self-custody, stablecoin pairs and pool-based pricing for the benefit of continuous access and instant settlement.
The notice therefore matters less as proof that 24/7 stock trading has arrived than as a detailed blueprint for testing it. If issuers object, liquidity fragments or token prices repeatedly detach from underlying shares, the experiment will expose the limits of the model. If the venue can maintain tight pricing, reliable backing and credible controls, it could give regulators and established exchanges evidence that tokenization can become part of mainstream market infrastructure. The technology is ready to run continuously. The harder challenge is making market quality continuous too.
