Why credit card fraud alerts are rising, and how worried you should be about them

It’s a scenario most people have encountered: you try to make a big or unexpected purchase on your credit card, and, at the moment you need it the most, the card gets declined.
Sometimes, it’s as simple as confirming the purchase via text message, and you can quickly complete the transaction. Other times, it’s a days-long process that involves confirmation codes, mailed letters and waiting on hold with the card company to validate that it was indeed you who wanted to buy the product.
The rate of fraud alerts is “absolutely” going up, according to Deloitte U.S. risk & financial advisory principal Satish Lalchand.
It can’t be ignored, because many of the alerts are not false alarms.
About 60% of credit card holders in 2023 experienced some sort of attempted fraud, according to Experian.
“Fraud in general across all channels, whether it’s check fraud, credit card fraud payments, the peer-to-peer payments, everything, is significantly increasing at a very rapid pace,” Lalchand said.
Global card losses attributed to fraud reached $33 billion in 2022, according to payments industry research company Nilson Report, with the U.S. market representing roughly 40% of losses. It has forecast a persistent threat that could reach nearly $400 billion in card fraud in the decade to 2032.
AI is part of the problem, but it is also part of the solution at companies including Visa.
“What’s driving a lot of this type of fraud, is the fraudsters themselves are using AI in general,” Lalchand said. “So, they are able to now move much faster.”
In the past, cybercriminals could open five to ten accounts a day. Now, it’s hundreds, if not thousands of accounts, thanks to advancements in artificial intelligence.
But at the same time AI is helping to detect potentially problematic transactions, with the downside of many cases turning out to be false alarms.
“When we come down to credit cards, financial institutions are investing more in the concept of fraud and fraud modernization, replacing older technology and having better fraud detection capabilities, and retuning their alerts,” Lalchand said. “That’s also causing a lot more on the detection side to go up.”
More personal data is being stolen
Michael Bruemmer, Experian vice president and head of its global data breach resolution and consumer protection division, says a lot more fraud is being done in other ways than stealing your credit card number, using other portions of your financial background, identity background, social security number.
Just in the past five months, there have been four major data breaches including Ticketmaster, Change Healthcare, AT&T and National Public Data. More data breaches can lead to more scrutiny and more preemptive alert protocols, although they are often not the main reason for alerts, according to Experian.
There is some good news. Overall, the rate of false purchases on credit cards is actually decreasing, according to Experian. There have been 416,582 cases of credit card fraud that have been perpetrated in 2024. It’s down 5.4% versus 2023.
AI’s ability to detect patterns based on previous behavior has helped. While you may still get credit card blocks on purchases that seem out of the ordinary, technology has improved fraud alerts in other ways. MasterCard said it’s observed on average a 20% increase in its ability to detect fraud thanks to AI, and up to 300% increase in its ability to detect fraud without more false alerts. Mastercard declined to provide statistics on the absolute level of fraud and overall accuracy of fraud detection.
On Thursday, Mastercard announced the acquisition of payment fraud company Recorded Future, which it already partners with to help identify cards that have been compromised.
“We’ve come such a long way to actually reduce the friction out there,” said Johan Gerber, Mastercard executive vice president and head of security solutions.
Take for example, travel plans and making purchases in a foreign country. Before, people would have to call the credit card company. Now, card companies automatically note vacations and travel patterns based on past purchase behavior. Technology has also made it faster to identify and clear flagged fraud alerts if it is indeed a false alarm. Instead of having to call and wait on hold, in many cases verification can be done in a matter of minutes through authorized related accounts or through information only the individual cardholder would know.
Tips to cut down on unnecessary alerts
Today, some scenarios will raise concerns within current security parameters. Experian notes that while data breaches may turn up the dial on fraud alerts, it’s actually changes in shopping patterns that are guaranteed to set off red flags. If you’re buying something at a new store or purchasing a big ticket item that you don’t usually buy, that’s typically something that will be noted. MasterCard also said trying multiple transactions quickly in a row will always alert their systems. So, you can expect these will usually garner some sort of temporary block.
“It’s a balance,” Gerber said. “Do I want to be inconvenienced? Do you potentially want a transaction that [MasterCard] may get wrong because [we] declined you? Or do I want to sit on the other side of the loss of trust in that [we] actually did let a transaction through and you should have known it’s not me.”
Other things you can do to ensure that you get mostly accurate fraud alerts is to sign up for monitoring services and personally set limit alerts on your accounts. Most institutions will let you place monetary limits on when you can get notified about big transactions. Freezing your credit file, using a password manager and using two-factor authentication for your financial accounts with a biometric passcode can also be beneficial.
“Try to shop on regular, reputable shopping sites, and if you’re going to use a credit card, have a low-level limit credit card that’s only used for those shopping sites,” Bruemmer said. “I would also recommend using a tap-to-pay or a mobile app and then make sure you’re not shopping on a public Wi-Fi network.”
And, even if the alerts may be annoying, never ignore them. Even though it may seem like you get notice of a data breach every day, it doesn’t mean you won’t eventually be affected.
“Consumers should pay attention to all of this, because it’s just a matter of time … they will be impacted,” Lachland said.

Shares of advertising technology company AppLovin and stock trading app Robinhood Markets each jumped about 7% in extended trading on Friday after S&P Global said the two will join the S&P 500 index.
The changes will go into effect before the beginning of trading on Sept. 22, S&P Global announced in a statement. AppLovin will replace MarketAxess Holdings, while Robinhood will take the place of Caesars Entertainment.
In March, short-seller Fuzzy Panda Research advised the committee for the large-cap U.S. index to keep AppLovin from becoming a constituent. AppLovin shares dropped 15% in December, when the committee picked Workday to join the S&P 500. Robinhood, for its part, saw shares slip 2% in June when it was excluded from a quarterly rebalancing of the index.
The S&P 500 already has a heavy concentration of large technology companies. Datadog and DoorDash entered earlier this year.
It’s normal for stocks to go up on news of their inclusion in a major index such as the S&P 500. Fund managers need to buy shares to reflect the updates.
AppLovin and Robinhood both went public on Nasdaq in 2021.
Robinhood has been a favorite among retail investors who have bid up shares of meme stocks such as AMC Entertainment and GameStop.
AppLovin itself became a stock to watch, with shares gaining 278% in 2023 and over 700% in 2024. As of Friday’s close, the stock had gained only 51% so far in 2025. AppLovin’s software brings targeted ads to mobile apps and games.
Earlier this year, AppLovin offered to buy the U.S. TikTok business from China’s ByteDance. U.S. President Donald Trump has repeatedly extended the deadline for a sale, most recently in June.
At Robinhood’s annual general meeting in June, a shareholder asked Vlad Tenev, the company’s co-founder and CEO, if there were plans for getting into the S&P 500.
“It’s a difficult thing to plan for,” Tenev said. “I think it’s one of those things that hopefully happens.”
He said he believed the company was eligible.
Shares of MarketAxess, which specializes in fixed-income trading, have fallen 17% year to date, while shares of Caesars, which runs hotels and casinos, are down 21%.

U.S. Federal Trade Commission Commissioner Rebecca Slaughter raised questions on Friday about the status of an artificial intelligence chatbot complaint against Snap that the agency referred to the Department of Justice earlier this year.
In January, the FTC announced that it would refer a non-public complaint regarding allegations that Snap’s My AI chatbot posed potential “risks and harms” to young users and said it would refer the suit to the DOJ “in the public interest.”
“We don’t know what has happened to that complaint,” Slaughter said on CNBC’s ‘The Exchange.” “The public does not know what has happened to that complaint, and that’s the kind of thing that I think people deserve answers on.”
Snap’s My AI chatbot, which debuted in 2023, is powered by large language models from OpenAI and Google and has drawn scrutiny for problematic responses.
The DOJ did not immediately respond to a request for comment. Snap declined to comment.
Slaugther’s comments came a day after President Donald Trump held a White House dinner with several tech executives, including Google CEO Sundar Pichai, Meta CEO Mark Zuckerberg and Apple CEO Tim Cook.
“The president is hosting Big Tech CEOs in the White House even as we’re reading about truly horrifying reports of chatbots engaging with small children,” she said.
Trump has been attempting to remove Slaughter from her FTC position, but earlier this week, U.S. appeals court allowed her to maintain her role.
On Thursday, the president asked the Supreme Court to allow him to fire her from the post.
FTC Chair Andrew Ferguson, who was selected by Trump to lead the commission, publicly opposed the complaint against Snap in January, prior to succeeding Lina Khan at the helm.
At the time, he said he would “release a more detailed statement about this affront to the Constitution and the rule of law” if the DOJ were to eventually file a complaint.

Google leads monster week for tech, pushing megacaps to combined $21 trillion in market cap

From the courtroom to the boardroom, it was a big week for tech investors.
The resolution of Google’s antitrust case led to sharp rallies for Alphabet and Apple. Broadcom shareholders cheered a new $10 billion customer. And Tesla’s stock was buoyed by a freshly proposed pay package for CEO Elon Musk.
Add it up, and the U.S. tech industry’s eight trillion-dollar companies gained a combined $420 billion in market cap this week, lifting their total value to $21 trillion, despite a slide in Nvidia shares.
Those companies now account for roughly 36% of the S&P 500, a proportion so great by historical standards that Howard Silverblatt, senior index analyst at S&P Dow Jones Indices, told CNBC by email, “there are no comparisons.”
There was a certain irony to this week’s gains.
Alphabet’s 9% jump on Wednesday was directly tied to the U.S. government effort to diminish the search giant’s market control, which was part of a years-long campaign to break up Big Tech. Since 2020, Google, Apple, Amazon and Meta have all been hit with antitrust allegations by the Department of Justice or Federal Trade Commission.
A year ago, Google lost to the DOJ, a result viewed by many as the most-significant antitrust decision for the tech industry since the case against Microsoft more than two decades earlier. But in the remedies ruling this week, U.S. District Judge Amit Mehta said Google won’t be forced to sell its Chrome browser despite its loss in court and instead handed down a more limited punishment, including a requirement to share search data with competitors.
The decision lifted Apple along with Alphabet, because the companies can stick with an arrangement that involves Google paying Apple billions of dollars per year to be the default search engine on iPhones. Alphabet rose more than 10% for the week and Apple added 3.2%, helping boost the Nasdaq 1.1%.
Analysts at Wedbush Securities wrote in a note after the decision that the ruling “removed a huge overhang” on Google’s stock and a “black cloud worry” that hung over Apple. Further, they said it clears the path for the companies to pursue a bigger artificial intelligence deal involving Gemini, Google’s AI models.
“This now lays the groundwork for Apple to continue its deal and ultimately likely double down on more AI related partnerships with Google Gemini down the road,” the analysts wrote.
Mehta explained that a major factor in his decision was the emergence of generative AI, which has become a much more competitive market than traditional search and has dramatically changed the market dynamics.
New players like OpenAI, Anthropic and Perplexity have altered Google’s dominance, Mehta said, noting that generative AI technologies “may yet prove to be game changers.”
On Friday, Alphabet investors shrugged off a separate antitrust matter out of Europe. The company was hit with a 2.95-billion-euro ($3.45 billion) fine from European Union regulators for anti-competitive practices in its advertising technology business.
Broadcom pops
While OpenAI was an indirect catalyst for Google and Apple this week, it was more directly tied to the huge rally in Broadcom’s stock.
Following Broadcom’s better-than-expected earnings report on Thursday, CEO Hock Tan told analysts that his chipmaker had secured a $10 billion contract with a new customer, which would be the company’s fourth large AI client.
Several analysts said the new customer is OpenAI, and the Financial Times reported on a partnership between the two companies.
Broadcom is the newest entrant into the trillion-dollar club, thanks to the company’s custom chips for AI, already used by Google, Meta and TikTok parent ByteDance. With Its 13% jump this week, the stock is now up 120% in the past year, lifting Broadcom’s market cap to around $1.6 trillion.
“The company is firing on all cylinders with clear line of sight for growth supported by significant backlog,” analysts at Barclays wrote in a note, maintaining their buy recommendation and lifting their price target on the stock.
For the other giant AI chipmaker, the past week wasn’t so good.
Nvidia shares fell more than 4% in the holiday-shortened week, the worst performance among the megacaps. There was no apparent negative news for Nvidia, but the stock has now dropped for four consecutive weeks.
Still, Nvidia remains the largest company by market cap, valued at over $4 trillion, with its stock up 56% in the past 12 months.
Microsoft also fell this week and is on an extended slide, dropping for five straight weeks. Shares are still up 21% over the last 12 months.
On the flipside, Tesla has been the laggard in the group. Shares of the electric vehicle maker are down 13% this year due to a multi-quarter sales slump that reflects rising competition from lower-cost Chinese manufacturers and an aging lineup of EVs.
But Tesla shares climbed 5% this week, sparked mostly by gains on Friday after the company said it wants investors to approve a pay plan for Musk that could be worth up to almost $1 trillion.
The payouts, split into 12 tranches, would require Tesla to see significant value appreciation, starting with the first award that won’t kick in until the company almost doubles its market cap to $2 trillion.
Tesla Chairwoman Robyn Denholm told CNBC’s Andrew Ross Sorkin the plan was designed to keep Musk, the world’s richest person, “motivated and focused on delivering for the company.”
