Wall Street is closely watching upcoming earnings from $NVDA and $WMT, with investors viewing both companies as key signals for the broader US economy. Nvidia is expected to provide another major read on AI spending and data center demand, while Walmart’s results could reveal how consumers are handling inflation, higher interest rates, and overall spending pressure. Together, the two companies are being seen as critical “bellwethers” for both tech momentum and consumer health, making this one of the most important earnings weeks for markets in 2026.
