Key Takeaways

  • Nasdaq (NDAQ) has fully restored all systems following a network disruption at its Carteret, New Jersey facility that caused intermittent data gaps across all US equities markets.
  • The technical issue impacted multiple multicast groups, including hardware and software feeds for Nasdaq, Nasdaq Texas, and Nasdaq PSX, specifically affecting both primary "A" and secondary "B" feeds.
  • Market participants were advised to switch to backup feeds originating from Nasdaq’s Chicago facility during the outage to maintain access to market data.
  • The disruption occurred amidst a broader tech sell-off, with the Nasdaq Composite falling more than 1.4% in early Thursday trading due to concerns over rising inflation and AI-related debt.

System Restoration and Technical Impact

Nasdaq (NDAQ) announced on Thursday, October 15, 2026, that it has successfully resolved a network disruption that caused "intermittent gapping" across its US equities market data feeds. The exchange operator confirmed that all systems are now operating normally after an alert was originally issued at 11:27 a.m. ET regarding issues at its Carteret data center.

The outage was widespread, affecting several multicast groups and impacting both the primary and secondary data feeds for the Nasdaq, Nasdaq Texas, and Nasdaq PSX exchanges. During the disruption, Nasdaq instructed clients experiencing data gaps to submit recovery requests for missing information and encouraged a transition to unaffected backup feeds located in Chicago.

Market Context and Volatility

The technical glitch coincided with significant volatility in the technology sector. The Nasdaq Composite (COMP) dropped approximately 1.88% in the previous session and continued its decline on Thursday, falling another 1.4% at the opening bell.

Investor sentiment has been pressured by a hotter-than-expected Consumer Price Index (CPI) report, which showed inflation rising to 3.7% in September. This has fueled fears of further interest rate hikes by the Federal Reserve, increasing the cost of capital for high-growth companies like Nvidia (NVDA), which saw its shares slip nearly 2% in tandem with the broader market rout.

Impact on AI and Semiconductor Stocks

The disruption added to a nervous atmosphere for artificial intelligence and semiconductor firms. CoreWeave (CRWV), a major AI infrastructure provider, saw its stock tumble over 15% on Wednesday and continued to slide on Thursday as investors questioned the sustainability of high capital expenditures in a rising rate environment.

Other major tech players, including Advanced Micro Devices (AMD) and Micron (MU), also faced downward pressure, falling roughly 3.5% and 4.5% respectively in premarket trading. While Nasdaq (NDAQ) has resolved the technical "gapping" issues, the exchange continues to monitor its systems to ensure stability as trading volumes remain high during this period of market repricing.
