Amazon vs. Walmart: The Retail War Just Picked a Winner

Amazon (NASDAQ:AMZN | AMZN Price Prediction) and Walmart (NYSE:WMT) reported earnings revealing two companies of nearly identical scale but radically different profit architectures. Amazon closed fiscal 2025 with annual revenue of $716.92 billion, while Walmart finished fiscal 2026 with $713.16 billion. The revenue gap is negligible, but the strategy gap is enormous.

AWS Carries Amazon. Omnichannel Carries Walmart.

Amazon’s Q4 story belongs to cloud and advertising, not stores. AWS grew 24% year-over-year to $35.58 billion, its fastest pace in 13 quarters. AWS generates the lion’s share of Amazon’s consolidated profit. Advertising Services added $21.32 billion, up 23%, building on partnerships with Netflix, Spotify, and SiriusXM.

Walmart’s quarter ran on physical stores fused with digital fulfillment. Global eCommerce grew 24% in Q4, with Walmart U.S. eCommerce up 27%, now representing 23% of Walmart U.S. net sales, a record high. Store-fulfilled expedited delivery grew more than 50%, and advertising grew 37% globally including VIZIO, with Walmart Connect U.S. up 41%.

Capital Allocation: $200 Billion Bet vs. Disciplined Execution

Amazon plans to spend approximately $200 billion in capital expenditures across Amazon in 2026, focused on AI infrastructure, custom silicon, and satellite internet. Jassy called it a bet on “seminal opportunities like AI, chips, robotics, and low earth orbit satellites.” This spending crushes free cash flow near-term.

Walmart’s capital posture is disciplined: CapEx guidance for FY2027 is approximately 3.5% of net sales, roughly $25 billion, directed at store remodels, automation, and fulfillment infrastructure.

Walmart’s automation is producing results. About 50% of eCommerce fulfillment center volume is now automated, and store-fulfilled delivery reaches 95% of U.S. households in under three hours.

Amazon’s same-day delivery items grew nearly 70% year-over-year and serve roughly 100 million customers. However, infrastructure costs are substantial, with Q4 CapEx alone at $39.52 billion, up 41.99% year-over-year.

Tariffs and Trade Policy Risk

Both companies flagged tariff uncertainty as meaningful risk. Amazon’s exposure runs through its third-party marketplace and global supply chain for hardware.

Walmart faces tariff pressure in general merchandise sourcing, though grocery dominance provides insulation since food spending reached $1,552.9 billion annually as of January 2026, a category where Walmart holds structural advantages.

For Amazon, the question is whether AWS momentum sustains through a massive investment cycle. The Trainium chip platform grows at triple-digit rates, and Amazon Bedrock is now used by more than 100,000 companies. That is a real moat. Whether a $200 billion annual capex budget earns adequate returns over five years remains uncertain.

The Case for Walmart Right Now

Both companies execute well. Walmart’s stock is up 14.46% year-to-date, while Amazon is down 4.15% year-to-date.

Walmart generates growing free cash flow of $14.92 billion, pays a rising dividend, and buys back shares aggressively. Amazon compresses free cash flow intentionally, betting a $200 billion infrastructure build pays off in cloud and AI.

Walmart’s profile — growing free cash flow, rising dividend, and omnichannel execution — appeals to investors prioritizing near-term capital returns.

Amazon’s AWS trajectory, growing 24% with triple-digit chip platform expansion, targets a multi-year infrastructure payoff in cloud and AI. Walmart’s free cash flow strength, dividend growth, and omnichannel momentum already showing in results give it a more defined near-term return profile.
