Top 20 U.S. Stocks by Trading Volume: Tesla Delivery Slide Continues

On Wednesday, Tesla led U.S. stock volume at $37.07 billion, rising 4.97%, despite Q2 deliveries of 384,122 vehicles, down 13.5% year-over-year—marking two consecutive quarters of decline.  

Tesla’s Q1 report in April showed 336,700 global deliveries, down 32% quarter-over-quarter and 13% year-over-year, the lowest since Q4 2022, yet ARK Invest bought 56,368 shares worth $18 million Tuesday amid a prior 5% drop.  

 

Second-ranked NVIDIA gained 2.58% with $26.62 billion in volume. OpenAI ruled out large-scale use of Google’s TPU chips, sticking with NVIDIA GPUs and AMD AI accelerators for their “proven performance” and existing supply deals.  

 

Investors and analysts had eyed a potential TPU partnership as a sign of OpenAI seeking NVIDIA alternatives, with Morgan Stanley strategists betting on Google hardware’s market edge.  

 

However, OpenAI’s chip roadmap signals NVIDIA and AMD remain core suppliers, potentially capping Google’s AI hardware share growth despite TPU advances.  

 

Third-ranked Apple rose 2.22% with $14.34 billion in volume. Jefferies upgraded its rating from “underperform” to “hold,” citing potential upside in Q3 iPhone sales, with Counterpoint Research data showing 15% global shipment growth in April-May—the strongest since 2021—boosted by China’s March price cuts.  

 

Fourth-ranked Robinhood surged 6.12% to a record high with $10.84 billion in volume, launching a 24/7 tokenized stock trading platform, including unlisted shares of OpenAI and SpaceX.  

 

Seventh-ranked Strategy rose 7.76% with $6.87 billion in volume, adding to its Bitcoin holdings for three straight quarters.  

 

From June 23-29, it bought 4,980 Bitcoin at ~$106,801 each ($531.9 million), yielding 19.7% since early 2025, holding 597,325 Bitcoin bought at ~$70,982 each, totaling $424 billion as of June 29.  

 

Tenth-ranked UnitedHealth fell 5.70% with $5.65 billion in volume. The Senate Rules Committee rejected a key clause from Trump’s “grand bill” to limit state Medicaid provider taxes for federal funds, ruled procedurally flawed by legal counsel Elizabeth McDonough.  

 

This policy clash stems from a May House bill freezing the tax, used by 49 states to fund hospitals and clinics, with the Senate version proposing deeper cuts to curb state overfunding via federal Medicaid.  

 

Eleventh-ranked AMD rose 1.77% with $5.39 billion in volume.  

 

Twelfth-ranked Google A shares gained 1.59% with $5.16 billion in volume. A filing shows Google proposed new search result adjustments to counter growing competitor criticism, with an EU meeting set for July 7-8 in Brussels to discuss, amid a potential new antitrust fine after March charges of favoring its own services like Google Shopping.  

 

Thirteenth-ranked Oracle rose 5.03% with $5.02 billion in volume. As part of the “Stargate” project, OpenAI agreed to lease significant computing power from Oracle data centers, highlighting AI’s massive needs—4.5 gigawatts of power, enough for millions of U.S. homes, with 1 gigawatt powering ~750,000 households.  

 

Unnamed insiders noted OpenAI’s Stargate, launched in January at the White House, partners with Oracle and Crusoe to build a major data center in Abilene, Texas.  

 

Fifteenth-ranked Coinbase Global rose 5.70% with $4.33 billion in volume. Cathy Wood’s ARK trimmed holdings in Coinbase and Roblox recently.  

 

Twentieth-ranked health insurer Centene Corp plunged 40.37%—its worst drop since 2006—with $3.26 billion in volume, withdrawing its full-year profit outlook after revenue underperformed in 22 of 29 market states, representing 72% of members, due to higher-than-expected morbidity, per actuary firm Wakely, slashing $1.8 billion in risk-adjusted revenue, or $2.75 per share.
