Cryptocurrency is being used more frequently in illegal transactions — about $158 billion was used in illicit crypto activity last year. That’s an all-time high, according to a new report from the startup TRM Labs. This comes as the overall crypto ecosystem is growing and, it should be said, legitimate uses of crypto are growing at a faster rate than illegitimate ones. Marketplace’s Stephanie Hughes spoke with Ari Redbord, global head of policy at TRM Labs and one of the authors of the new report, to learn more.

NASA’s Artemis II mission, which will send humans around the moon for the first time in over five decades, could launch as early as March. This is part of a larger campaign to establish a long-term presence on the moon and eventually prepare for human space flight to Mars.

Meanwhile, China also has a goal of landing humans on the moon by 2030, setting up a kind of modern space race. One reason for the rush: It's like a game of finders keepers, said Saadia Pekkanen, a professor focused on space law and policy at the University of Washington.

Graphics processing units (GPUs) have become the most important commodity in the AI boom — and have made Nvidia a multi-trillion dollar company. But the tensor processing unit (TPU) could present itself as competition for the GPU.

TPUs are developed by Google specifically for AI workloads. And so far, Anthropic, OpenAI and Meta have reportedly made deals for Google’s TPUs.

Christopher Miller, historian at Tufts University and author of "Chip War: The Fight for the World's Most Critical Technology," explains what this could mean.

According to surveys by the FINRA Foundation, our knowledge of personal finance here in the U.S. went down by 15% between 2009 and 2021. But what if it actually didn't? What if the technology we use to answer the questions is now getting in the way? In 2021, over half of all respondents used a smartphone to fill out the survey. In 2009, none of them used one, according to data from FINRA’s National Financial Capability Study. A new working paper finds that when people use smartphones for surveys they're more likely to respond with the wrong answer or say they don't know. Marketplace’s Stephanie Hughes spoke with Montana State University economics professor Carly Urban, one of the authors of the paper, to learn more.

On this week’s “Marketplace Tech Bytes: Week in Review,” we take a look at Nvidia's changing investment relationship with OpenAI. Plus, a stormy start for the new U.S. version of TikTok. But first, SpaceX, one of the world’s largest rocket companies, announced this week that it’s buying xAI, a two-and-half-year-old artificial intelligence startup. Both companies are controlled by Elon Musk. The new company is reportedly valued at $1.25 trillion. It means the chatbot Grok, the satellite internet company Starlink, and the social media firm X are all going to co-exist under the same rocket hangar. Marketplace’s Stephanie Hughes spoke with Paresh Dave, senior writer at Wired, about what adding these companies together equals.
