Tesla deliveries drop for second straight year; stock on pace to match longest losing streak ever

BYD outsold Tesla in battery electric vehicles for the first time in 2025.

Tesla Q4 deliveries fell 16% to 418,227 vehicles, falling short of estimates, while its full-year numbers dropped 8.5% to 1,636,129, marking the electric vehicle company’s second annual sales decline in a row.

Shares of the company fell 2.8% in afternoon trading, putting the stock on pace for its seventh straight day in the red. The stock has dropped 11% over that time. The last time Tesla slipped for seven straight sessions, its longest losings streak on record, was April 2024.

Meanwhile, Chinese competitor BYD saw its 2025 battery electric vehicle sales increase 28% to 2.3 million, overtaking Tesla for the first time on a calendar year basis.

After a record third quarter, in which the sunsetting $7,500 federal EV tax credit pulled forward demand, Tesla’s lower numbers represent a disappointing aftermath, wherein its cars and electric vehicles generally have effectively become more expensive, reducing demand. At the same time, CEO Elon Musk has been deemphasizing Tesla’s EV business, focusing the future of the company instead on autonomy, AI, and robots.

Ahead of the results, Tesla released its own compilation of analyst estimates that pegged the Q4 numbers at about 423,000 and full-year deliveries at 1.6 million. The move was widely seen as a way to lower investor expectations for the quarter, since other consensus estimates by Bloomberg and FactSet were notably higher. Tesla also released lower-cost, stripped-down versions of its Model Y and Model 3, whose new prices are still more than older versions with the federal tax credit.

On the company’s last earnings call, Musk said Tesla is so confident in the future success of its Full Self-Driving technology that it planned to increase vehicle production “as fast as we reasonably can,” potentially reaching a 3 million annualized production rate within two years.

For now, Tesla has not reached its goal of removing safety drivers from its Austin Robotaxi vehicles, and demand for its vehicles is not there.

Google's YouTube maintains its top spot as streaming accounts for nearly half of all TV-watching time

People spent a record 47.5% of their TV-watching time on streaming platforms in December, according to new data from Nielsen, up from the previous record of 47.3% in July. Google’s YouTube once again was the most popular streaming service by time spent, but Netflix’s share inched slightly upward to 9% from 8.8% in July, while YouTube’s fell to 12.7% from 13.4%. The jump was largely thanks to “Stranger Things,” which was the most watched streaming title last month.

Amazon CEO says tariffs are inflating prices and buyers are looking for bargains

While the legality of President Trump’s tariffs winds its way through the courts, their effects are beginning to show up in prices.

During an interview at the World Economic Forum in Davos, Switzerland, Amazon CEO Andy Jassy said he is starting to see tariffs “creep into” pricing, as some sellers are “passing on those higher costs to consumers in the form of higher prices.”

Jassy said that while consumers are still spending, they are becoming more price conscious.

“I think that wherever they can, they are trying to trade down in price — they are looking for bargains wherever they can find bargains,” he said. “I see people a little more hesitant on higher-priced discretionary items.”

Trump has maintained that other countries are footing the bill for his tariffs. But new research suggests Americans will ultimately be the ones paying those higher prices.

Musk: Tesla restarting Dojo supercomputer effort as “AI5 chip design is in good shape”

Tesla CEO Elon Musk said in a post on X over the weekend that the company plans to restart work on its Dojo supercomputer, dubbed Dojo3, saying that the AI5 chip the company had been developing is in “good shape.”

The Dojo supercomputer trains Tesla’s AI models, including the one behind its all-important Full Self-Driving tech. The company stopped work on Dojo in August. “It doesn’t make sense for Tesla to divide its resources and scale two quite different AI chip designs,” Musk said at the time. “The Tesla AI5, AI6 and subsequent chips will be excellent for inference and at least pretty good for training.”

“Pretty good” appears to be good enough.

In the interim, Tesla relied more on companies like Nvidia and Advanced Micro Devices for AI training. Restarting Dojo suggests Tesla plans to bring at least some AI training back in-house.

Musk also runs AI company xAI, which has its own supercomputer and a substantial business relationship with Tesla. A plurality of Tesla shareholders recently voted in favor of investing in Musk’s AI company, but the board declined to approve the measure because of a large number of abstentions.

EPA: xAI’s Colossus data center illegally used gas turbines without permits

The Environmental Protection Agency has ruled that xAI violated the law when it used dozens of portable gas generators for its Colossus 1 data center without air quality permits.

When xAI set out to build Colossus 1 in Memphis, Tennessee, CEO Elon Musk wanted to move with unprecedented speed, avoiding all of the red tape that could slow such a big project down.

To power the 1-gigawatt data center, Musk took advantage of a local loophole that allowed portable gas generators to be used without any permits, as long as they did not spend more than 364 days in the same spot. That allowed xAI to bring in dozens of truck-sized gas generators to quickly supply the massive amount of power the data center needed to train xAI’s Grok model.

The new EPA rule says the use of such portable generators falls under federal regulation, and the company did need air quality permits to operate the turbines. xAI is also using dozens of such generators to power its Colossus 2 data center just over the border in Alabama.
