It’s been a tough November for Palantir.

Shares of the software analytics provider dropped 16% for their worst month since August 2023 as investors dumped AI stocks due to valuation fears. Meanwhile, famed investor Michael Burry doubled down on the artificial intelligence trade and bet against the company.

Palantir started November off on a high note.

The Denver-based company topped Wall Street’s third-quarter earnings and revenue expectations. Palantir also posted its second-straight $1 billion revenue quarter, but high valuation concerns contributed to a post-print selloff.

In a note to clients, Jefferies analysts called Palantir’s valuation “extreme” and argued investors would find better risk-reward in AI names such as Microsoft and Snowflake. Analysts at RBC Capital Markets raised concerns about the company’s “increasingly concentrated growth profile,” while Deutsche Bank called the valuation “very difficult to wrap our heads around.”

Adding fuel to the post-earnings selloff was the revelation that Burry is betting against Palantir and AI chipmaker Nvidia. Burry, who is widely known for predicting the housing crisis that occurred in 2008 and the portrayal of him in the film “The Big Short,” later accused hyperscalers of artificially boosting earnings.

Palantir CEO Alex Karp vocally hit the front lines, appearing twice in one week on CNBC, where he accused Burry of “market manipulation” and called the investor’s actions “egregious.”

“The idea that chips and ontology is what you want to short is bats— crazy,” Karp told CNBC’s “Squawk Box.”

Despite the vicious selloff, Palantir has notched some deal wins this month. That included a multiyear contract with consulting firm PwC to speed up AI adoption in the U.K. and a deal with aircraft engine maintenance company FTAI.

But those announcements did little to shake off valuation worries that have haunted all AI-tied companies in November.

Across the board, investors have viciously ditched the high-priced group, citing fears of stretched valuations and a bubble.

In November, Nvidia pulled back more than 12%, while Microsoft and Amazon dropped about 5% each. Quantum computing names such as Rigetti Computing and D-Wave Quantum have shed more than a third of their value.

Apple and Alphabet were the only Magnificent 7 stocks to end the month with gains.

Sill, questions linger over Palantir’s valuation, and those worries aren’t a new concern.

Even after its steep price drop, the company’s stock trades at 233 times forward earnings. By comparison, Nvidia and Alphabet traded at about 38 times and 30 times, respectively, at Friday’s close.

Karp, who has long defended the company, didn’t miss an opportunity to clap back at his critics, arguing in a letter to shareholders that the company is making it feasible for everyday investors to attain rates of return once “limited to the most successful venture capitalists in Palo Alto.”

“Please turn on the conventional television and see how unhappy those that didn’t invest in us are,” Karp said during an earnings call. “Enjoy, get some popcorn. They’re crying. We are every day making this company better, and we’re doing it for this nation, for allied countries.”

Palantir declined to comment for this story.

Here are five key things investors need to know to start the trading day:

Stock futures trading was halted this morning after a data center “cooling issue” took down several Chicago Mercantile Exchange services. Individual stocks were still trading before the bell, while the CME said futures indexes and options trading would open fully at 8:30 a.m. Follow live markets updates here.

The stock market has rebounded during the holiday-shortened trading week. But the three major indexes are still on pace to end November’s trading month — which ends with today’s closing bell — in the red. The Dow and S&P 500 are poised to snap six-month winning streaks, while the Nasdaq Composite is on track to see its first negative month in eight.

Today’s trading session ends early at 1 p.m. ET.

Black Friday was once considered the biggest in-person shopping day of the year, drawing huge crowds to stores in search of bargains. But while millions are still expected to partake in the occasion, it’s not what it used to be.

Here’s what to know:

• In the past six years, online sales have outpaced brick-and-mortar spending on Black Friday. Data shows in-person foot traffic has been mostly flat over the last few years, as well.
• No matter where they make their purchases, shoppers are also skeptical that they’re getting the best deals.
• As CNBC’s Gabrielle Fonrouge reports, the shift has meant a change in strategy for many of the retail industry’s biggest names. Some have started offering their holiday sales earlier in the season, while others are spacing out their promotions.
• Deloitte reported that the average consumer will shell out $622 between Nov. 27 and Dec. 1, a decrease of 4% from last year.
• Even as the day of deals loses its allure, AT&T found that Gen Z participates the most, while their older counterparts do their shopping closer to Christmas.

Alphabet has been a notable exception to the recent tech downturn. Shares of the Google parent have surged more than 13% this month as Wall Street sees the company as an AI leader.

Alphabet began the month by announcing its latest tensor processing units, or TPUs, called Ironwood. Last week, the company launched its latest AI model, Gemini 3, which caught positive attention from Silicon Valley heavyweights.

Shares of the stock are now up close to 70% this year, making it the best-performer within megacap tech. But experts told CNBC’s Jennifer Elias that Alphabet’s lead in the competitive AI market is marginal and could be hard to hold onto.

The Alphabet-Nvidia AI race isn’t the only tech rivalry that has heated up in recent days.

Alibaba‘s AI-powered smart glasses went on sale yesterday. With its new wearable tech offering, the Chinese tech company is going up against major players — namely Meta, which unveiled its smart glasses with Ray Ban in September.

Meanwhile, Counterpoint Research found Apple is poised to ship more smartphones than Samsung this year for the first time in 14 years. Apple is also poised to boast a larger market share, driven by strong iPhone 17 sales.

American shoppers are increasingly looking to South Korea for their cosmetics. NielsenIQ found U.S. sales of so-called “K-beauty” products are slated to surge more than 37% this year to above $2 billion.

Retailers ranging from beauty product hubs Ulta and Sephora to big-box chains Walmart and Costco are jumping on the trend. On top of that, Olive Young — aka the “Sephora of Seoul” — is opening its first U.S. store in Los Angeles next year.
