Mexico blocks Walmart's acquisition of grocery delivery app Cornershop for $225M citing Walmart's size and Cornershop's access to Walmart's competitor data
Daina Beth Solomon / Reuters : Tweets: @dainabethcita Tweets: Daina Beth Solomon / @dainabethcita : Walmart wanted to buy delivery app Cornershop for $225 million. Mexico said no. Here's why the competition regulator feared Walmart could displace rivals also on the app - and why Walmart couldn't save the deal: https://www.reuters.com/... @Reuters #scoop
Context & Ripple Effects
Walmart had already folded Cornershop into its e-commerce playbook once: its $225M acquisition of the delivery marketplace was announced in September 2018, positioning the Chile- and Mexico-based app as Walmart's last-mile grocery arm in Latin America. The regulator's veto now unwinds that plan, and the stated concern is structural rather than routine — Walmart's size plus Cornershop's visibility into rival merchants' volumes on the same platform.
The block lands mid-pivot: two weeks later, Walmart de Mexico announced grocery delivery over WhatsApp at roughly $2.55 per 90-minute drop, showing the retailer building delivery channels it fully controls instead of buying one.
First-order effects
- Cornershop stays independent in Mexico and Chile, and Walmart loses the $225M asset it had counted on for Latin American last-mile grocery — while rival grocers selling through the app keep their sales data out of a direct competitor's hands.
- Walmart must serve Mexican grocery demand through owned channels like the WhatsApp delivery service rather than an acquired marketplace.
Second-order effects
- An independent Cornershop becomes acquirable by someone other than Walmart — and the coverage shows exactly that outcome, with Uber buying the startup months later, adding Chile, Mexico, Peru, and Canada to its footprint.
- Mexico's ruling hands other competition regulators a template: blocking a dominant retailer from owning a neutral multi-vendor marketplace because of the data asymmetry, not just market share.
Third-order effects
- If data-access concerns become a standard veto ground, large retailers will face a harder path to consolidating delivery marketplaces they also compete on, pushing them toward owned channels or minority stakes instead of outright acquisition.
- Delivery apps gain leverage as contested assets: a startup blocked from one buyer can shop itself to a ride-hailing or logistics player, reshaping who owns the last mile in Latin American grocery.
The trend: Antitrust review is shifting from market-share arithmetic to platform-data conflicts, deciding which giants may own the neutral marketplaces they sell through.
