Worldwide markets roiled by data-center snafu in Chicago suburb

Published

5 days ago

November 30, 2025

One of the first signs of trouble arrived at 9:41 p.m. Eastern time on Thursday, when most of Wall Street was shut and traders were still enjoying the Thanksgiving holiday in the US.

“Due to technical issues,” CME Group Inc. said in a one-line email to clients, its futures and options “markets have been halted.”

The problem, it turned out, was the cooling system at a data-center complex in the suburban town of Aurora, Illinois, some 50 miles (80 kilometers) from Chicago, which serves as the main hub for trillions of dollars of derivatives traded each day. Inside, temperatures soared past 100F (38C) despite the frigid weather, according to people familiar with the matter.

At the time, the CME’s information indicated the outage at the facility — run by private-equity owned CyrusOne — would be brief, according to a person with direct knowledge of the situation. As a result, it opted against switching over to a backup facility near New York City.

But before long, the magnitude of that fateful decision would become painfully clear. Despite a flurry of emails from CME assuring clients the problem would be fixed in the “near term,” the malfunction persisted and brought down vast parts of the global financial system for hours. From Tokyo to London, and eventually New York, trading in everything from gold and oil to wagers on the direction of US interest rates came to an abrupt halt.

Even after trading was largely restored on Friday, disruptions extended well into the US session, with CME Direct, a trading platform provided by the exchange, offline for most of the day.

The outage underscored a vulnerability in increasingly integrated global markets that rely on a handful of dominant exchanges. It also raises questions about the contingency plans of CME, one of the world’s largest exchanges for derivatives contracts, and its heavy reliance on the data center it sold in 2016 to CyrusOne, a company now owned by KKR & Co. and Global Infrastructure Partners.

The shutdown “shows how concentrated futures markets really are — there just aren’t many alternative venues for the main products,” said Thomas Texier, group head of clearing at Marex Group Plc, a London brokerage.

The 10-hour outage surpassed the one that hit CME in 2019 and again underscored how much the exchange has become an integral part in the world’s markets. On average in October, derivatives trading volumes amounted to more than 26 million contracts every day, according to data from the group.

While it came during a day when US trading was expected to be subdued — due to the Thursday holiday — it still proved vexing to investors around the globe who needed to make month-end adjustments by rolling positions from one contract to another.

In Singapore, one oil trader said when the initial alert was issued, they thought it was a hoax because the trades and quotes were still streaming in. But a few minutes later, the screen suddenly froze and they were booted out of the Nymex platform. A trader in London thought he had Wi-Fi connection issues.

“We’ve had to trade some cash Treasuries today and it was noticeably thinner and wider,” said James Athey, a portfolio manager at Marlborough Investment Management Ltd. “Month-end, day after Thanksgiving, CME down. It’s not an ideal combo.”

By the end of the trading day Friday, CME had restored all of its trading operations, including CME Direct. A representative for the exchange declined to comment beyond the updates it had provided to clients throughout the day.

CyrusOne said in a statement that problem was caused by a machinery failure that affected the systems used to cool its computer systems and it was “working around the clock to restore normal operations as quickly and safely as possible.” It said it had successfully restarted several chilling systems at limited capacity and deployed temporary cooling equipment to supplement its operations.

It’s unclear what exactly happened to CyrusOne’s cooling system. But the data center does have a redundancy system and offers free cooling when temperatures fall below 30F, according to information on CyrusOne’s website.

The 450,000-square-foot Aurora complex has served as the primary hub of digital operations for CME for nearly two decades. It’s famous among high-frequency traders and Wall Street firms, who’ve long jostled for positions around the site to get an edge on competitors by shaving fractions of a second off the time it takes for trades.

In 2016, CME decided it wanted to shift away from owning infrastructure and sold the site to Dallas-based CyrusOne. As part of the deal, CME agreed to rent space from CyrusOne for 15 years so it could continue to house the computers at the site that keep its markets running, essentially outsourcing its day-to-day operations. KKR and Global Infrastructure Partners agreed to buy CyrusOne in 2021.

The center has continued to serve as a key node for traders across the globe, and the impact was felt broadly. In London hours, for example, the trading of US Treasury futures was halted, gold saw erratic moves and US crude and palm oil on the Bursa Malaysia exchange were also affected.

Even as the trading system was restored, some market makers remained hesitant to engage in trades until they could be assured the problem was fixed, according to people familiar with the matter.

Others saw the occurrence during what’s typically a slow day in the US as one saving grace.

“I woke up thinking my Wi-Fi was out,” said Ritik Katte, chief investment officer at MCD Capital, a London-based investment firm. “Liquidity is lower than usual, so it seems like the Thanksgiving holiday has been extended.”

Stocks: Facing a vast wave of incoming liquidity, the S&P 500 prepares to surf to a new record high

Published

The S&P 500 index ticked up 0.3% yesterday, its eighth straight upward trading session. It is now less than half a percentage point away from its record high, and futures were pointing marginally up again this morning. Nasdaq 100 futures were even more optimistic, up 0.39% before the open in New York. The VIX “fear” index (which measures volatility) has sunk 12.6% this month, indicating that investors seem to have settled in for a calm, quiet, risk-on holiday season.

They have reason to be happy. Washington is preparing a wave of incoming liquidity that is likely to generate fresh demand for equities.

For instance, the CME FedWatch index shows an 87% chance that the U.S. Federal Reserve will deliver an interest rate cut next week, delivering a new round of cheaper money. Further cuts are expected in 2026.

Furthermore, Wall Street largely expects President Trump to announce that Kevin Hassett will replace Fed chairman Jerome Powell in May—and Hassett is widely regarded as a dove who will lean in favor of further rate cuts.

Elsewhere, the Fed has begun a series of “reserve management purchases,” a program in which the central bank will buy short-term T-bills—a move that will add more liquidity to markets generally.

Banks, brokers and trading platforms are also lining up to handle ‘Trump Accounts,’ into which the U.S. government will deposit $1,000 for every child. The trust fund can be invested in low-cost stock index trackers—a new source of investment demand coming online in the back half of 2026.

So it’s no surprise that nine major investment banks polled by the Financial Times expect stocks to rise in 2026; the average of their estimates is by 10%.

The Congressional Budget Office also estimates that the One Big Beautiful Bill Act will add 0.9% to U.S. GDP next year largely because it allows companies to immediately deduct capital expenditures from their taxes—spurring a huge round of corporate spending.

With all that fresh money on the horizon, it’s clear why markets have shrugged off their worries about AI and Bitcoin. The only shock will be if the S&P fails to hit a new all-time high by the end of the year.

Here’s a snapshot of the markets ahead of the opening bell in New York this morning:

S&P 500 futures were up 0.2% this morning. The last session closed up 0.3%.
STOXX Europe 600 was up 0.3% in early trading.
The U.K.’s FTSE 100 was up 0.14% in early trading.
Japan’s Nikkei 225 was up 2.33%.
China’s CSI 300 was up 0.34%.
The South Korea KOSPI was down 0.19%.
India’s NIFTY 50 is up 0.18%.
Bitcoin was flat at $93K.

Gen Z fears AI will upend careers. Can leaders change the narrative?

Good morning. Are you communicating the purpose of AI with your younger employees? According to new data from Harvard, most fear AI is going to take their jobs.

The Institute of Politics at Harvard Kennedy School released the fall 2025 Harvard Youth Poll on Thursday, which finds a generation under profound strain. The nationwide survey of 2,040 Americans between 18 and 29 years old was conducted from Nov. 3–7. For these respondents, instability—financial, political, and interpersonal—has become a defining feature of daily life.

Young Americans see AI as more likely to take something away than to create something new. A majority (59%) see AI as a threat to their job prospects, more than immigration (31%) or outsourcing of jobs to other countries (48%).

Nearly 45% say AI will reduce opportunities, while only 14% expect gains. Another 17% foresee no change and 23% are unsure—and this holds across education levels and gender.

In addition, young people fear AI will undermine the meaning of work. About 41% say AI will make work less meaningful, compared to 14% who say it will make work more meaningful and 19% who think it will make no difference; a quarter (25%) say they are unsure.

In my conversations this year with CFOs and industry experts, many have said that the goal of using AI is to remove the mundane and manual aspects of work in order to create more meaningful, thought‑provoking opportunities. However, that message does not yet seem to be resonating with younger employees.

There is a lot of public discussion and widespread fear that AI will mostly take away jobs, but research by McKinsey Global Institute released last week offers a different perspective. According to the report, AI could, in theory, automate about 57% of U.S. work hours, but that figure measures the technical potential in tasks, not the inevitable loss of jobs, as Fortune reported.

Instead of mass replacement, McKinsey researchers argue the future of work will be defined by partnerships among people, agents, and robots—all powered by AI, but dependent on human guidance and organizational redesign. The primary reason AI will not result in half the workforce being immediately sidelined is the enduring relevance of human skills.

The Harvard poll also found young people have greater trust in AI for school and work tasks (52% overall, 63% among college students) and for learning or tutoring (48% overall, 63% among college students). But trust drops sharply for personal matters.

Young employees are considered AI natives. However, it is important to recognize that they have not experienced as many major technology shifts as more seasoned employees—like the dawn of the internet. It’s not to say that AI won’t change the workforce, but there’s still room and need for humans. It’s up to leaders to clearly communicate how AI will change roles, which tasks it will automate, and also provide ongoing training and guidance on how employees can still grow their careers in an AI-powered workplace.

Have a good weekend. See you on Monday.

Big Deal

The ADP National Employment Report, released on Dec. 3, indicated that private-sector employment declined by 32,000 jobs in November. ADP found that job creation has been flat during the second half of 2025, while pay growth has continued its downward trend. In November, hiring was particularly weak in manufacturing, professional and business services, information, and construction.

“Hiring has been choppy of late as employers weather cautious consumers and an uncertain macroeconomic environment,” said Nela Richardson, chief economist at ADP, in a statement. “And while November’s slowdown was broad-based, it was led by a pullback among small businesses.”

ADP’s report is an independent measure of labor market conditions based on anonymized weekly payroll data from more than 26 million private-sector employees in the U.S. The next major U.S. Jobs Report (Employment Situation) for November is scheduled for release on Dec. 16 by the Bureau of Labor Statistics.

Here are four Fortune weekend reads:

Overheard

“The Fed no more ‘determines’ interest rates than a meteorologist determines the weather.”

—Alexander William Salter states in a Fortune opinion piece. Salter is a senior fellow with the Independent Institute and an economics professor in the Rawls College of Business at Texas Tech University. He writes: “The Fed doesn’t set interest rates. As powerful as America’s central bank is, it’s still just one player in a globe-spanning ocean of financial markets. Instead, the Fed sets targets for short-term interest rates. Those target rates indicate the Fed’s general monetary policy stance, but they are not the substance of monetary policy.”

Four key questions about OpenAI vs Google—the high-stakes tech matchup of 2026

Published

1 hour ago

December 5, 2025

Jace Porter

Hello, Tech Editor Alexei Oreskovic, pitching in for Allie. We’ve been enjoying some crisp blue-sky days here in San Francisco in true December fashion. For the folks at OpenAI however, the days have been red — Code Red.

In case you haven’t been following, OpenAI CEO Sam Altman on Monday declared a “Code Red” alert in a memo to employees, according to the Information and the Wall Street Journal. The alert, the highest level on OpenAI’s three-point scale, is essentially an all-hands-on-deck call to mobilize and defend against an imminent threat. That threat is Google and its latest version of the Gemini AI model, which competes with OpenAI’s GPT family of models, particularly its flagship ChatGPT product.

It’s a remarkable turn of events, almost exactly three years to the day that OpenAI released ChatGPT and put Google and the rest of the tech industry on the back foot. Now Google is on the ascent, hoping to turn OpenAI into MySpace. Of course, with its $500 billion valuation, OpenAI and its investors are not about to surrender.

So, as the two AI superpowers roll up their sleeves for what’s sure to be a 2026 slugfest, we thought it would be interesting to tap into the wisdom of Term Sheet readers and ask for your perspectives on some of the key questions of this critical moment in tech history. Send your thoughts directly to me or to Allie G.

How can a company like OpenAI turn a first-mover advantage into a sustainable and long-lasting business that doesn’t get bulldozed by giants with more resources and capital?

Is there a lesson—good or bad—from a first mover of the past (e.g. Netscape vs Microsoft; Blackberry vs iPhone) that OpenAI should heed?

What is the Google Achilles heel that OpenAI should exploit?

What is the single most important thing that OpenAI needs to execute on right now – and what is the best metric to measure its success?

And of course, what other important parts of this story should we be thinking about?

Fire away!
