SEC Lines Up BlackRock, NYSE, Robinhood for 24/7 Stock Trading Push — Can Wall Street’s Plumbing Handle It?

SEC Taps Blackrock, Robinhood, NYSE and More for 24-Hour Trading Push

The U.S. Securities and Exchange Commission plans to host a public roundtable on Sept. 17 to examine what it would take to run U.S. stock trading around the clock, according to the source’s summary of the agency’s announcement. The event is slated for the SEC’s Washington headquarters from 10 a.m. to 4 p.m. ET and will be streamed on the SEC’s website, per the source.

Who’s at the table

The source reports that more than 17 panelists from major market players are expected, including BlackRock, Citadel Securities, NYSE, Nasdaq, Robinhood, Interactive Brokers, Citi, UBS, Cboe, DTCC, Invesco, Charles Schwab, Samsung, Jane Street, State Street, BNP Paribas and BNY Pershing.

What the SEC plans to probe

According to the source’s description of the SEC’s agenda, the discussion will focus on core mechanics needed for nonstop trading:

Exchange and broker‑dealer operational readiness
Surveillance capabilities for thinly staffed overnight sessions
Clearance and settlement processes functioning during hours markets haven’t historically operated

Markets are already stretching the clock

The source states that Nasdaq is targeting Dec. 6 for a new overnight session that would bring the trading day close to 23 hours, pending final regulatory approval.

Separately, the source reports that 24 Exchange — backed by Steve Cohen’s Point72 Ventures — has already won SEC approval to operate a stock exchange with roughly 23 hours of trading five days a week.

According to the source, NYSE floated its own extended‑hours model in 2024, with executives indicating the idea was influenced in part by crypto markets’ 24/7 trading. The source also says Citadel Securities sent the SEC a 29‑page letter last year urging clear rules and stronger infrastructure before broader extended hours roll out.

What to watch next

Per the source, the Sept. 17 roundtable is open to the public and will stream live. Any widespread move to extended or 24‑hour stock trading would still require regulatory steps; the roundtable is positioned as fact‑finding on operational readiness.
