U.S. stock futures climbed Monday as investors positioned for a packed week of economic data and corporate earnings. GDP and inflation reports are set to provide fresh insights into the economy's trajectory, while Walmart takes center stage in another round of blue-chip earnings.

Markets are bracing for the Commerce Department's release of first-quarter GDP figures, which could confirm whether the economy is maintaining momentum or showing signs of slowing. The Personal Consumption Expenditures (PCE) price index, the Federal Reserve's preferred inflation gauge, will also be closely watched for clues on future interest rate policy.

Walmart's quarterly results come amid heightened investor scrutiny of consumer spending trends. As the largest U.S. retailer, its performance often serves as a bellwether for broader retail sector health. The earnings season has already delivered mixed signals, with some companies beating estimates while others warn of persistent inflationary pressures on margins.
