Tesla is coming full circle back to a time when its sales and earnings didn't much matter, and investors focus on future potential.
Why it matters: Tesla's EV sales last year hit their lowest level since 2022, but the company's stock is increasingly tied to its AI ambitions — including humanoid robots and robotaxis.
A year into the second Trump administration, the Cybersecurity and Infrastructure Security Agency is smaller, leaner and at the center of a growing debate over what the nation's cyber mission should look like.
Why it matters: CISA is at the front lines of protecting U.S. government agencies and private companies from nation-state and cybercriminal digital threats, but it now has fewer people and resources to carry on that work.
Meta and YouTube are about to face a landmark trial in Los Angeles over claims their platforms deliberately addict and harm young people, kicking off a wave of high-profile lawsuits that could reshape the social media landscape.
Why it matters: The outcome could determine how thousands of similar lawsuits against social media platforms will play out nationwide.
Why it matters: The move underscores Amazon's ongoing effort to refine its grocery strategy — even as the business now generates more than $150 billion in annual sales.
Why it matters: UPS was getting 12% of its revenue from Amazon deliveries before deciding to pare back those shipments in pursuit of a more profitable, efficient business.
Driving the news: The shipping giant will cut up to 30,000 "operational positions" in 2026, CFO Brian Dykes said Tuesday on an earnings call.
That "will be accomplished through attrition" plus a new "voluntary separation program for full-time drivers," he said.
The company also plans to close 24 buildings in the first half of the year while evaluating additional facilities for closure in the second half.
"Plus, we plan to further deploy automation across the network," Dykes said.
By the numbers: UPS had already cut 48,000 positions in 2025, including 15,000 fewer seasonal roles, as it adjusted to lower volume.
All told, the company expects to save $3 billion from the Amazon shipment cuts.
The other side: "Considering drivers overwhelmingly rejected it the first time, UPS may try to resurrect its disrespectful buyout program, but Teamsters still know our worth," the Teamsters union — which represents UPS workers — said in a statement.
"We're perfectly happy for UPS to realize growth and cost savings on the backs of corporate managers so long as they uphold their contractual commitments to our members and reward the Teamsters who actually make the company run."
Editor's note: This story has been updated with a statement from the Teamsters union.
Yahoo is joining the next era of search with Yahoo Scout, a new AI answer engine that has a standalone site and app, and will be available across its properties.
Why it matters: As search moves from a list of links to conversations and answers, Yahoo is betting its three decades of data can help it compete with newer rivals.
Four members of the Magnificent 7 tech stocks report their quarterly results this week, with earnings for the group expected to grow by nearly 17%.
Why it matters: This is the "most eventful week" of the earnings season as investors weigh whether the AI darlings can keep fueling this bull market, writes José Torres, senior economist at Interactive Brokers.
We scrambled the debut of our "Behind the Curtain" video series: Anthropic CEO Dario Amodei wanted to chat Monday after he dropped a 38-page essay warning of escalating risks from the AI technology he's helping pioneer.
We asked Amodei, in San Francisco, what Congress should do now, and what lawmakers should tell their constituents. His three-part prescription:
Transparency legislation to require AI companies to disclose their models' risks and bad behavior, and the defenses that are built in.
Cut off sales of Nvidia chips and other U.S. products that help China.
Get ready to tax future AI trillionaires and redistribute wealth. He said he'd tell his fellow future trillionaires: "You're going to get a mob coming for you if you don't do this in the right way."
The bottom line: "We always assume that everything that can go wrong does go wrong," Amodei said. "That's how you build things that are reliable."
