NYSE American Options trading halt, October 23, 2026

Trading on NYSE American Options was halted on Friday morning, October 23, 2026, after a technical issue at the exchange, and NYSE announced on Monday morning, October 26, 2026 that the underlying software defect had been addressed and trading would resume at 7:30 AM Eastern that day. The New York Stock Exchange disclosed the halt on its status page and in a notification to participants, according to Bloomberg and Seeking Alpha reporting. Other options exchanges disregarded quotes from NYSE American Options while the halt was in effect, according to exchange statements reported by Bloomberg. NYSE Arca Options declared self-help against NYSE American Options and suspended routing to it, then revoked that self-help late on Friday.

Timeline: times are Eastern, which is also the exchange's local time, so Eastern and provider-local times are the same for this incident. On NYSE's own Market Status history page, the incident detail records: at 10:18 AM Eastern on October 23, NYSE American Options said it was investigating a reported technical issue; at 10:41 AM Eastern, it suspended trading in all underlying symbols on TXN 4 and 6; at 11:35 AM and 12:14 PM Eastern, it said the issues continued in all underlying symbols on TXNs 4 and 6 and that suspension and cancellation of orders and quotes was in process; at 1:51 PM Eastern, all open orders and quotes on TXN 6 had been canceled, with cancellation on TXN 4 still in progress; at 2:04 PM Eastern, NYSE said the affected symbols will remain suspended for the remainder of the day, with cancellation on TXN 4 still in progress; at 4:10 PM Eastern, NYSE said cancellation of all pending orders and quotes on TXN 4 has now been completed, trading remains suspended in all underlying symbols on TXNs 4 and 6, and all other systems are operating normally. Separately, at 10:31 AM Eastern, NYSE Arca Options declared self-help against NYSE American Options, with routing suspended at 10:26 AM Eastern; at 4:49 PM Eastern, NYSE Arca Options revoked its self-help, with routing to NYSE American Options resumed at 4:46 PM Eastern. That Arca routing resumption was not a resumption of NYSE American Options trading on TXNs 4 and 6. Bloomberg Law reported the halt at 11:16 AM Eastern (15:16 UTC) and Seeking Alpha reported it at 11:39 AM Eastern (15:39 UTC). Markets were closed Saturday and Sunday, October 24 and 25, and no Market Status history entry was dated those days. On Monday, October 26, 2026 at 7:01 AM Eastern, NYSE added a resumption update to the same incident thread, marked Normal, stating that the Exchange has addressed the underlying software defect and trading will resume at 7:30 AM Eastern on Monday, October 26, 2026; the site banner read "System Status: Normal" when the update was read live at 7:24 AM Eastern. In that update NYSE also gave its fullest account of Friday: the matching engines on TXN 4 (187 underlying symbols) and TXN 6 (244 underlying symbols) became impaired shortly after the 9:30 AM Eastern transition from the early session to the core session, due to excessive internal messaging and queues triggered by a software defect; early recovery and suspension efforts were unsuccessful; receipt of incoming orders and quotes began to be inhibited at about 11:29 AM Eastern; NYSE decided not to resume trading on the affected TXNs that day; the queues on TXN 6 were cleared by about 1:37 PM Eastern and on TXN 4 by about 3:49 PM Eastern, and order and quote cancellation was completed. The suspension therefore covered the remainder of the Friday, October 23 session, and the venue resumed at its next session, the Monday 7:30 AM Eastern early session for eligible symbols, ahead of the 9:30 AM Eastern core open.

Affected services and scope: NYSE American Options, the options exchange operated by the New York Stock Exchange group (Intercontinental Exchange), specifically the underlying symbols on TXN 4 and TXN 6: 187 symbols on TXN 4 and 244 symbols on TXN 6, 431 symbols in total on NYSE's Monday account. Bloomberg describes the venue as one of 20 US options venues, accounting for about 10 percent of the more than 70 million US equity options contracts that trade each day. NYSE equities trading was not reported as halted. The affected facility is the NYSE market complex at Mahwah, New Jersey, as listed for NYSE on the Outages board; no report names a different facility for this halt.

Provider's account: NYSE attributed the halt to a technical issue, and in its October 26 update to a software defect that triggered excessive internal messaging and queues on the TXN 4 and TXN 6 matching engines shortly after the 9:30 AM Eastern session transition on October 23. Its Friday updates record the investigation, the suspension, progressive cancellation of open orders and quotes (TXN 6 complete by 1:51 PM Eastern, TXN 4 complete by 4:10 PM Eastern), and that the affected symbols would remain suspended for the remainder of Friday, with all other systems operating normally. Its October 26 update states the defect has been addressed and trading will resume at 7:30 AM Eastern on October 26. No indication of a cyberattack has been reported, and no compensation has been stated.

Status: Restored October 26, 2026. NYSE's resumption update was posted at 7:01 AM Eastern on October 26, 2026, with trading to resume at 7:30 AM Eastern the same day and the incident thread marked Normal; verified live on October 26, 2026 at 7:24 AM Eastern (SecurTek outage watch, 7:23 AM Eastern sweep, live browser check by Jim Callahan; the check preceded the 7:30 AM resumption by minutes, so it verifies NYSE's official resumption notice and Normal status, with post-resumption trading to be confirmed in the next sweep).
