President Donald Trump said Friday that Russia will supply millions of tons of diesel to the global market under a deal he struck with President Vladimir Putin.

Russia will immediately supply more than 300,000 tons of diesel, followed by 500,000 tons in November, and 1 million tons immediately thereafter, Trump said in a post on Truth Social. Moscow will then deliver another 3 million tons of diesel based on the condition of Russia's refineries, Trump said.

Diesel prices have surged around the world as Ukraine has pounded Russian refineries, forcing Moscow to ban diesel exports to the global market. Iran and its Houthi allies have also attacked refineries in the Middle East, further constraining fuel supplies. Read more.

Shares of Moderna and Novavax jumping Friday after The New York Times reported that the NIH plans to launch a public-private effort to speed development of personalized cancer vaccines.

The vaccine program is expected to start in December and focus on pancreatic cancer, liver cancer and colorectal cancer, as well as certain pediatric tumors. Many of the experimental treatments use mRNA technology to train the immune system to attack proteins unique to tumors.

The read-through is clearest for Moderna, which is already developing a personalized mRNA cancer vaccine with Merck. The stock is up more than 600% so far in 2026, the best performing S&P 500 constituent year-to-date.

Public opposition to data center construction and negative sentiment about artificial intelligence in general are growing, setting up AI as one of the defining political issues of the 2026 midterm elections, set for Nov. 3.

Wall Street has gone all-in betting on AI, with total capital expenditures expected in excess of $5 trillion by 2030. That spending is accelerating even as the technology remains largely unproven in terms of profitability and productivity.

With electoral and financial forces at odds, equity markets and national politics could be on a collision course in November over the fate of the AI buildout, and some analysts say the fallout could persist well beyond the election.

"What I consistently hear from investors is that the opposition to data centers is really about the political backlash and that after the midterms things get a lot better. But I think that after the midterms, things get worse," Ed Mills, a political analyst at Raymond James, told CNBC. "That is a huge blind spot for the market."

The ability of U.S. families to stay current on their debts worsened over the past three years, hitting levels not seen since the aftermath of the global financial crisis, the Federal Reserve reported Friday.

In the central bank's Survey of Consumer Finances, researchers found that while wealth disparities narrowed somewhat, the ability to meet debt payments deteriorated significantly.

"Families were more likely to be behind on their financial obligations than at any point since the 2010 survey," stated the survey, a data-rich document the Fed releases every three years to chronicle the nation's financial health.

Consumer sentiment declined further in early October, hitting its second lowest on record in the latest University of Michigan survey amid higher inflation expectations.

The survey's index of sentiment came in at 46.3, down 3.7% from September and the worst going back to May, when the reading hit its lowest level in data going back to November 1952. Economists surveyed by Dow Jones had been looking for 47. Similarly, the current conditions index fell 12.2% to 44.7, though the expectations measure increased 2.2% to 47.3.

On inflation, the one-year outlook rose to 4.7%, up fractionally from a month ago to the highest since May. The five-year outlook also edged higher to 3.5%, also to its highest since May.

"Overall, sentiment for lower-income consumers and those with smaller stock porfolios dropped steeply this month, groups that have fewer resources to weather increases in prices," said survey director Joanne Hsu. "Frustration over cost-of-living continues to mount, as consumers across the political spectrum believe that the trajectory of the economy has weakened since the beginning of the year."

Cboe Global Markets is likely to continue gaining ground following the renewal of its S&P Dow Jones Indices (DJI) contract, according to Morgan Stanley. 

The investment bank double upgraded Cboe to overweight from underweight. It also hiked its price target on shares to $358 from $258, implying nearly 22% upside from Thursday's close. 

In late September, Cboe extended its agreement that gives its exclusive rights to list and offer trading of options on the S&P 500 Index, some of the most widely traded instruments in the world.

"The S&P DJI extension through 2051 addresses a key underpinning of our prior UW, while options growth has proved more durable than we expected and we see attractive optionality with new prediction markets product launch," analyst Michael Cyprys said Friday in a note to clients. "This is in the context of negative investor sentiment and positioning yet attractive valuation."

Airtel Money, the mobile banking unit of London-listed telecoms group Airtel Africa, is set to begin conditional trading of its shares on Friday ahead of its admission to the London Stock Exchange on Oct. 14.

The company has set 270 million shares at a fixed price of £1.96 ($2.60), implying an estimated market capitalization at admission of £5.3 billion.

Airtel Money reported $1.35 billion in revenue and $676 million in adjusted earnings in the year to June 2026 and has 53 million monthly active users.

The float is expected to be one of the biggest in the U.K. capital since fintech Wise made its £8.75 billion IPO in 2021. Wise has since moved its main listing to New York in a major blow to London, which has lost a steady stream of mid- to large-scale companies in recent years.

Dan Coatsworth, head of markets at AJ Bell, said in a September note that investors would be "rejoicing as the UK stock market is finally getting an IPO that isn't a tiny natural resources company," but noted that Airtel Money would not raise new money from the sale, which will come from existing minority shareholders including TPG and the Qatar Investment Authority,

U.S. Treasury yields were largely stable on Friday, with the benchmark 10-year yield falling less than one basis point to 5.227%, while the 30-year yield was little changed at 5.608%.

Both remained near multi-decade highs amid concerns over persistent inflation and elevated government borrowing.

Swiss private bank UBP raised its estimated fair-value range for the 10-year Treasury yield to 4.75%–5.25% in its October outlook, citing renewed inflationary pressures. The bank said in a note on Friday that risks to yields had become more balanced, although visibility remained limited, prompting it to maintain a neutral duration stance of four years and favor income from bond holdings rather than taking directional bets on interest rates.

UBP also expects the Federal Reserve to tighten monetary policy gradually, with rate cuts unlikely before the second half of 2027.

Oil fell Friday as U.S. President Donald Trump's comments on Iran calmed nerves, following reports that America was considering resuming strikes against Tehran.

Futures for international benchmark Brent crude for December delivery dropped 0.77% to $103.48 a barrel. U.S. West Texas Intermediate futures for November declined 0.68% to $90.87 per barrel.

Trump said in a post on Truth Social the U.S. "will not be attacking Iran at any time prior to the Midterm Elections," and was having "productive discussions" with Iran.

"In the meantime, accelerated IEA-coordinated stock releases and greater use of alternative export routes could help limit supply pressures," said Thadeu Dos Santos, regional director at markets trading platform Infinox.

"Saudi Arabia's continued use of its restored East-West pipeline is also allowing more crude to reach international markets without relying on the Strait of Hormuz, providing some offset to the upside risks," he added.

Australian AI data center operator Firmus, which is backed by Nvidia, has withdrawn its planned mega initial public offering, citing market volatility and conditions, the company said in an emailed statement to CNBC.

Firmus said its board determined that the terms of the proposed offering did not adequately reflect the strength of its business and long-term growth outlook.

"The board therefore concluded that proceeding with the offer was not in the best interests of the company and its shareholders," Firmus said in a statement. "Firmus will now pursue capital from the private markets and consider alternative public and private market options," it added.

Firmus had reportedly planned to raise $5 billion in its IPO, pricing shares at A$11 apiece, which woul have made it the second-largest new share sale in Australia's history. The IPO valued the company at around $30.6 billion.
