Intercontinental Exchange, which owns the New York Stock Exchange, is launching a new trading platform called OKXICE to enable 24/7 stock trading through tokenized shares. The platform, owned by ICE and an OKX affiliate, represents a significant departure from traditional Wall Street trading mechanisms.
Unlike conventional exchanges that use order books to match buyers and sellers at transparent prices, OKXICE will use automated liquidity pools similar to those found in decentralized finance platforms. Prices on OKXICE will be determined by the balance of assets in these pools rather than by NYSE prices or traditional bid-ask spreads.
How Tokenized Stock Trading Works
Under the SEC exemption issued in September, tokenized shares must provide equivalent rights to conventional shares, including dividends, voting rights, and other shareholder entitlements. Tokenization providers will acquire ordinary shares through registered broker-dealers and issue one digital token for each share held, with underlying stock backing the tokens one-for-one.
When trading on OKXICE, participants will deposit stock tokens and stablecoins into automated pools. The exchange's software will adjust prices as the token-to-dollar balance shifts, using technology similar to Uniswap's constant-product formula. This means larger purchases will face progressively higher prices as they consume available inventory.
Price Differences and Slippage
In a hypothetical pool containing 100 stock tokens and $10,000 in stablecoins with an initial $100 per-token price, a $1,000 buy order would yield approximately 9.09 tokens rather than ten shares—an average cost of $110 per token despite the reference price remaining at $100. Larger pools absorb orders with less price movement, making liquidity depth critical to execution costs.
The platform plans to display estimated execution terms, fees, and the gap between the reference stock value and expected purchase price. Users will be able to set slippage tolerance to limit how much worse a quoted deal can become before the transaction is rejected. However, rejected blockchain transactions can still incur network fees.
Operating Without Regulation NMS
OKXICE will not be subject to Regulation NMS, the framework governing ordinary price protections that connect US equity markets. However, the SEC has granted qualifying tokenized stock exchanges temporary, conditional relief from registering as conventional exchanges for five years, with requirements covering shareholder rights, permitted trading activity, issuer objections, and formal trading halts. Antifraud rules still apply, and brokers handling customer orders retain best-execution obligations.
Company Objections
Sixteen companies have objected to tokenized versions of their stocks trading on OKXICE as of October 19, including Microsoft, Alphabet, and Goldman Sachs. Fifteen of these objectors were on the exchange's original proposed roster of 62 companies, roughly 25 percent of that list. Under SEC rules, issuers can submit objections that prevent specific third-party tokenization offerings, though the objections do not necessarily stop other exchanges from offering tokenized shares under different arrangements.
Applied Optoelectronics provided a public statement of concern, with a company representative telling The Wall Street Journal that it was unsure how the trading might affect the stock's price, liquidity, or volatility, and did not want investors to mistake third-party tokens for company-sponsored products.
Around-the-Clock Trading Challenges
The 24/7 trading capability addresses demand from participants who want to respond immediately to company news or geopolitical events occurring outside regular market hours. However, OKXICE's smart contracts will not use stock-price feeds from the NYSE or elsewhere to determine pool execution prices. Instead, the exchange will display outside market prices for reference while relying solely on the assets in the pool to set trading prices.
This creates potential price divergences when market news breaks outside trading hours. Liquidity providers selling tokens during off-hours periods risk discovering that underlying stocks are worth significantly more or less when the main market reopens on Monday, while those buying tokens face the opposite risk.
Competitive Approach
OKXICE's model contrasts with Nasdaq's SEC-approved tokenized-securities rule for a DTC-linked pilot that brings eligible securities into an existing exchange structure with familiar stock-market mechanisms. OKXICE proposes an entirely different trading engine using independent pools and automated pricing.
OKXICE plans to make pool balances, completed trades, published transaction details, and daily pool-size information visible on-chain, allowing real-time comparison of trading costs across different times and market conditions. This transparency could demonstrate whether the model's theoretically expensive trades occur in practice or whether sufficient liquidity keeps prices competitive.
