Top 20 US Stock Trading Volumes:Tesla’s Robotaxi Hits the Road

On Monday, Tesla, the top-traded stock, surged 8.23% with a trading volume of $64.805 billion. Tesla’s Robotaxi service launched in Texas, operating within a small area near its Austin headquarters using Model X SUVs, with an estimated fleet of 10-20 vehicles. Tesla handpicked initial riders, including investors and social media influencers, some of whom livestreamed their trips.  

 

Stablecoin leader Circle, second in volume, rose 9.64%, extending its recent rally with $25.913 billion traded. By Monday’s close, its market cap neared $60 billion.  

 

Nvidia, third, gained 0.22% with $21.76 billion in volume.  

 

Microsoft, fourth, rose 1.80% with $11.846 billion traded. Xbox announced that starting this week, PC Game Preview users can access a new integrated game library on the Xbox PC app for Windows 11 PCs and portable devices.  

 

Separately, Denmark’s Digitalization Ministry plans to gradually shift from Microsoft Office to LibreOffice in coming months while continuing to use Windows.  

 

Apple, fifth, edged up 0.25% with $11.129 billion in volume. Reports indicate Apple is in “last-minute” talks with the European Commission to ease App Store rules. Apple was fined €500 million in April for violating the EU’s Digital Markets Act (DMA) but hasn’t announced App Store changes to avoid further penalties.  

 

Google’s Class A shares, seventh, fell 0.87% with $9.013 billion in volume. Google cut its smart TV division budget by 10% and reduced staff.  

 

AMD, eighth, rose 1.04% with $8.345 billion traded. Melius Research upgraded AMD to “Buy” in a Monday client report, raising its price target from $110 to $175.  

 

Analyst Benjamin Reitzes highlighted that growing inference demand for AI models applying patterns to new data will drive significant GPU deployments in 2026-2028.  

 

Reitzes noted that despite AMD’s 25% year-to-date gain, confidence in its AI prospects is strengthening. He believes hyperscale cloud providers and national projects may increasingly adopt AMD platforms if inference workloads surge as expected.  

 

Hims, ninth, crashed 34.63% with $7.739 billion in volume after Novo Nordisk ended their partnership, citing concerns over compounded drug sales and misleading marketing.  

 

Amazon, tenth, dipped 0.58% with $7.583 billion in volume. Amazon AWS confirmed a partnership with SK Group to build an AI data center in South Korea. AWS announced an expanded agreement with SK Group to construct a 100-megawatt data center, with Ulsan set to host a new AWS AI zone by 2027. SK Group aims to expand capacity to become an APAC data center hub.  

 

Separately, Amazon successfully launched its second batch of “Kuiper” internet satellites into low-Earth orbit on Monday, a key step in its satellite constellation plan and escalating competition with SpaceX’s Starlink.  

 

Meta Platforms, eleventh, rose 2.37% with $7.57 billion in volume. Meta’s $14.3 billion investment in Scale AI marks a major move to secure high-quality training data for AI models. The deal gives Meta a 49% stake in the data-labeling startup and brings Scale AI founder Alexandar Wang into Meta’s leadership to head a new superintelligence research lab.  

 

This acquisition addresses Meta’s urgent challenge in the AI race: securing specialized datasets for training competitive large language models. While rivals like OpenAI lead via ChatGPT, Meta’s recently launched Llama 4 model received a lukewarm response, with users citing poor performance in coding tasks compared to smaller competitors.  

 

CoreWeave, fifteenth, fell 5.39% with $4.555 billion in volume. Barclays recently downgraded CoreWeave from “Overweight” to “Equal Weight,” citing limited near-term upside despite long-term optimism.  

 

ExxonMobil, twentieth, dropped 2.58% with $2.97 billion in volume. International oil prices plunged over 7% on Monday, pressuring oil stocks like ExxonMobil.
