AI Drought Pushes NVIDIA Down, Elon Musk Excludes from Top 10; Walmart Family Surges into Top 3

In the wake of heightened AI-related cost and profitability concerns, NVIDIA (NVDA-US) shares weakened, causing Elon Musk's personal wealth to fall 80 billion dollars to $151.4B as of February 14, 2026, and move to No. 11 on the Bloomberg Billionaires Index. The week saw Musk's rank drop three places amid broader sell-off in AI-concept stocks. Conversely, Walmart (WMT-US) posted strong price momentum as its digital transformation and AI integrations gained investor traction, with the Walton family trio—Jim, Rob, and Alice Walton—surging to No. 8, 9, and 10, respectively, the highest-ranking achievement for the family since March 2020. Walmart's market value surpassed $1 trillion in early February, up 20% year-to-date, driven by its e-commerce platforms, rapid delivery services, and advertising data businesses. Walmart is expected to report fourth-quarter earnings on February 26, with analysts closely watching the actual profit contribution from AI applications.
