Counterfeits on Amazon skyrocketed after sales from Chinese-based sellers more than doubled in 2015. Here's how Amazon is trying to stop the problem.

Counterfeits became a big problem on Amazon after an influx of Chinese-based sellers joined in 2015, causing brands like Nike and Birkenstock to quit selling directly on the site. In 2020, Amazon launched the Counterfeit Crimes Unit, which joined law enforcement on 50 raids and the seizure of 7 million counterfeit products in 2023. But retail experts say it's not enough. CNBC visited Amazon's team of former prosecutors and a military gear brand that's partnered with them to sue counterfeiters.

CNBC got an exclusive look at Amazon's use of generative AI to optimize delivery routes, make more intelligent warehouse robots, and better predict where to stock new items.

Google makes custom AI chips called TPUs, and Apple uses them to train its AI models. CNBC got an exclusive look inside the lab where Google makes its chips.

Google was the first cloud provider to make its own custom AI chips, called TPUs, when they first came out in 2015 - a trend both Amazon and Microsoft followed years later. Now, Apple has revealed it uses TPUs to train its AI models, positioning Google chips as an alternative to Nvidia's market-leading GPUs. CNBC got an exclusive look inside the lab where Google makes its chips, where its top executive showcased TPU Version 6, and its new Arm-based CPU, Axion, both coming out later in 2024.
