Intercontinental Exchange and OKX are preparing an always-open market where tokenized US stocks could keep repricing after Wall Street closes.

On Oct. 4, OKXICE, the companies' 50-50 joint venture, notified the Securities and Exchange Commission (SEC) that it intends to launch a Tokenized Securities Venue under the regulator's new Innovation Exemption. The proposed platform would initially support 63 securities, including Nvidia, Tesla, Apple, Microsoft, JPMorgan , Goldman Sachs, Coinbase and Circle .

The structure would create a parallel trading venue for some of America's most actively traded companies that remains open 24 hours a day, seven days a week. Tokenized shares could continue absorbing information during nights and weekends when their underlying stocks are unavailable on traditional cash markets, potentially providing a reference for where prices may move when regular exchanges reopen.

ICE's involvement gives the experiment added significance. The owner of the New York Stock Exchange is directly participating in infrastructure that tests whether US equity trading can extend onto blockchain rails beyond conventional market hours.

“This is a landmark step toward a truly global, 24/7 Wall Street,” OKXICE co-chair and former New York Gov. Andrew Cuomo said . OKX founder and CEO Star Xu described the filing as a market-structure experiment worth testing at scale, adding that “Wall Street is moving onchain.”

The market structure becomes more consequential once traditional exchanges close because OKXICE's smart contracts will not rely on the prevailing NYSE or Nasdaq price to determine where a tokenized stock trades.

Instead, prices will be set by the ratio of assets held in automated market maker liquidity pools. External stock-market data can be used for displays and trading-halt checks, but it will not feed directly into the smart contracts determining executable prices.

If market-moving news involving Nvidia or Tesla emerges on a Saturday, investors could continue trading their tokenized shares against stablecoins. The resulting price would not determine where the underlying stock opens Monday, but a sufficiently liquid market could give traders a continuously updated indication of how investors are responding before conventional equity trading resumes.
