Mizuho maintains Walmart stock rating despite Amazon grocery push

Amazon's aggressive expansion of free same-day fresh grocery delivery to over 1,000 U.S. cities, targeting 2,300 locations by year-end, is intensifying retail competition and causing Walmart's stock to trade lower. This strategic move, underpinned by Amazon's robust Q2 financial performance and 10.87% revenue growth, signals a significant escalation in the grocery market, with a Mizuho survey indicating Walmart and Target are most vulnerable to market share loss, even as Amazon simultaneously strengthens its AWS and AI initiatives.

Analysis

Amazon is executing a multi-pronged strategic offensive, significantly intensifying competition in both retail and technology sectors. The expansion of its free same-day fresh grocery delivery to over 1,000 U.S. cities, with a target of 2,300 by year-end, represents a direct assault on incumbent retailers, evidenced by the immediate negative pressure on Walmart's stock. This move is supported by Amazon's robust financial health, including a reported 10.87% revenue growth and Q2 2025 earnings that surpassed guidance. While Mizuho maintains an Outperform rating on Walmart, it acknowledges this as an "escalation of head-to-head competition" and a consumer survey highlights Walmart and Target as most at risk of losing market share. Simultaneously, Amazon is fortifying its high-margin cloud and AI businesses. Amazon Web Services is deepening its government ties with up to $1 billion in cloud discounts and is integrating cutting-edge OpenAI models, prompting a Buy rating reiteration from BofA Securities with a $272 price target. Amazon's backing of Anthropic, which is now offering its Claude AI to the U.S. government, further solidifies its position in the critical AI landscape.

Key Decisions for Investors

• Given Amazon's aggressive cross-sector growth initiatives and strong analyst support with price targets up to $272, investors may view current positions as having a reinforced long-term bullish thesis, underpinned by dual growth engines in e-commerce and AI/cloud.
• Investors holding Walmart or Target should closely monitor competitive metrics in the coming quarters, as Amazon's focused grocery and rural expansion presents a material threat to market share, warranting a potential re-evaluation of exposure to traditional retail.
• While the outlook for Amazon appears strong, it is prudent to weigh the execution risk in the grocery sector, considering Mizuho's note that Amazon's past efforts, including the Whole Foods acquisition, did not fully meet expectations.
