U.S. FAA issues nationwide ground stop order; air traffic control communication glitch leads to flight suspensions, and FBI rules out cyberattack.

According to data from BIT Stock Platform, U.S. stocks closed on Friday: the Dow Jones Industrial Average posted a preliminary 0.1% gain, the S&P 500 index fell 0.4%, and the Nasdaq Composite dropped 0.91%. AMD (AMD.O) fell 8.75%, Dell (DELL.N) dropped 7.24%, Coreweave (CRWV.O) declined 6.13%, SanDisk (SNDK.O) fell 5.59%, and Broadcom (AVGO.O) fell 4.76%; SK Hynix ADR (SKHY.O) fell 4.3%, NVIDIA (NVDA.O) dropped 2.01%; Meta Platforms (META.O) rose 2.9%, and Microsoft (MSFT.O) gained 0.17%.

According to Air Current, the nationwide U.S. ground stop order is set to be lifted. After the U.S. Federal Aviation Administration (FAA) issued a nationwide ground stop order to all airports Friday morning due to a special situation, S&P 500-tracking ETFs temporarily fell 0.5% in after-hours trading, while Nasdaq 100-tracking ETFs dropped 0.8% at one point. Airlines were also weighed down by the news: United Airlines declined 1.2%, JetBlue Airways fell 2.4%, and American Airlines dropped 1.7%. Conversely, cybersecurity stocks advanced: Palo Alto Networks gained 2%, Zscaler rose 1%, and CrowdStrike increased 2%. The ground stop is tied to a communications frequency failure in the air traffic control (ATC) system. U.S. Transportation Secretary Sean Duffy previously said all en route air traffic control centers were affected by the communication issues, and technicians are probing the root cause of the fault. The Federal Bureau of Investigation (FBI) has concluded that the ATC communication outage was not caused by a cyberattack or criminal act. Investigators are currently checking whether the fault is linked to a software update.

On social media, a petition website calling on NVIDIA’s board to reinstate Jensen Huang saw a traffic surge that temporarily caused server overload. Replit CEO Amjad Masad publicly stated he contacted the page’s owner to help raise rate limits, and the site has since returned to normal operation. As of now, 11,098 people have signed the petition demanding Huang’s return, including 1,652 current employees, 172 former employees, and 6,544 supporters. On November 12, 2026, NVIDIA announced Jensen Huang’s resignation as chief executive officer, effective immediately, marking the end of his 33-year tenure leading the company he co-founded. The petition’s organizers and signatories fear Huang was forced out without due process or sufficient time to defend himself, and are demanding an explanation from the board. The open letter’s core demands to NVIDIA’s board are: 1. Reinstate Huang as CEO while an independent investigation clarifies the facts; if he is to remain away from the role, provide an evidence-backed explanation. 2. Ensure the investigation is independent, define its scope and timeline, and grant Huang a fair opportunity to defend himself. 3. Issue a timely public statement addressing relevant concerns, evidence, and the balance of interests for employees and shareholders. The letter stresses: “Three decades of leadership do not mean immunity from accountability, but accountability requires evidence and due process, not a public trial by the masses.” The website states the campaign is independent and has not been endorsed by NVIDIA or Huang personally. Earlier, Elon Musk posted that the petition to reinstate NVIDIA (NVDA.O)’s Jensen Huang is ongoing, and he will sign it in support.

Microsoft apologized on local time November 13 for a global service outage, stating the fault stemmed from a prior network capacity upgrade and was unrelated to cyberattacks or AI agents. The disruption took down services including Teams, Outlook, and Copilot across at least 70 countries and regions, impacting millions of users. Microsoft noted progress has been made in service restoration, though it is still working to clear backlogged messages, rebalance traffic, and resolve aftereffects of the outage. The company is currently unable to confirm an exact timeline for full recovery of all services.

Federal Reserve officials have delivered a flurry of hawkish remarks this week, cementing market expectations for a 25-basis-point rate hike in December and further opening the door to a consecutive rate increase in January next year. U.S. October CPI data showed accelerating inflation and expanding price pressures, while the year-on-year rise in wholesale prices in October also hit its highest level since 2022, further bolstering the case for rate hikes. New York Fed President John Williams said inflation remains too high; Chicago Fed President Austan Goolsbee called the latest data "concerning"; Dallas Fed President Lorie Logan noted that faster rate hikes than previously expected may be needed; Fed Governor Christopher Waller even raised the possibility of a 50-basis-point rate hike next month. Markets are now pricing in 25-basis-point rate hikes each in December, January, and March next year, up from earlier expectations of only hikes in December and March. Bank of America has included rate hikes at all three upcoming meetings in its forecast, while Santander projects hikes in December and March next year. However, there remains division among officials over the pace of rate hikes, with some advocating for gradual, small increases. Boston Fed President Susan Collins said the direction of further policy tightening is clear, but declined to pre-judge the size or speed of rate hikes. Rising rate hike expectations have pushed U.S. Treasury yields higher, but factors including a weak housing market, underwhelming AI investment returns that could trigger stock market declines, and future energy price drops remain variables the Fed must consider in its policy decisions.

According to CNBC, Nvidia’s board of directors is currently selecting a headhunting firm to recruit a new CEO. The board stressed that it has not yet formally approached any potential candidates, noting that speculation about a successor is premature. A Nvidia spokesperson subsequently confirmed the report’s authenticity. Earlier today, the Financial Times reported, citing sources familiar with the matter, that Nvidia’s board has reached out to Rene Haas, CEO of SoftBank-owned British chip design firm Arm, as part of its search for a permanent successor to Jensen Huang. Haas is one of several potential candidates. It remains unclear whether Nvidia will extend a formal offer, or whether Haas will accept it. Arm declined to comment, while Nvidia did not immediately respond to a request for comment. Haas spent about seven years at Nvidia earlier in his career, serving as vice president and general manager of the Computing Products business group. Insiders revealed that more than a decade after leaving Nvidia, he still maintains good relations with Jensen Huang and some Nvidia directors. Haas joined Arm in 2013, where he oversaw global sales and marketing before taking on the role of president of the IP Products Group. He has served as Arm’s CEO and a board member since February 2022.
