TBBB vs WMT: How BBB Foods and Walmart Compare (2026)

Same yardstick, side by side (as of August 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. TBBB and WMT share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined TBBB and WMT exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

BBB Foods runs Tiendas 3B, a hard-discount grocery format in Mexico built on the Aldi and Lidl playbook rather than the full-line supermarket one. Each store is small (typically a few hundred square meters), stocks a deliberately limited assortment of roughly a thousand SKUs, and leans overwhelmingly on private-label brands the company controls, which is what lets it undercut Walmart de Mexico's Bodega Aurrera and the traditional corner-store trade on everyday staples. The store base reached ~3,469 units at the end of the first quarter of 2026 after ~123 net openings in that quarter alone and ~580 over the trailing twelve months, roughly ~20% unit growth, and the company employs about ~29,200 people. Revenue is almost entirely merchandise sales, with a small recyclables line, and the model runs on negative working capital: suppliers are paid after inventory turns, so growth generates cash rather than consuming it.

Walmart is the largest retailer in the world by revenue and the biggest private employer in the United States. It runs more than 10,000 stores and clubs globally under the Walmart and Sam's Club banners, plus a large and fast-growing e-commerce and digital business. Its core proposition is everyday low prices on groceries and general merchandise, achieved through enormous purchasing scale and a highly efficient supply chain. Walmart makes most of its money from US grocery and general merchandise, but it is increasingly building higher-margin profit engines on top of that traffic: Walmart Connect (a retail advertising business), Walmart+ (a subscription membership), marketplace and fulfillment services for third-party sellers, and financial and health services. Roughly a quarter of revenue comes from outside the US, led by operations in Mexico (Walmex), China, and India (Flipkart). Headquartered in Bentonville, Arkansas, Walmart is a defensive, scale-driven retailer competing with Amazon, Costco, and Target.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• TBBB drivers: Store-count compounding in an underpenetrated market; Same-store sales that are still running in the mid-teens.
• WMT drivers: Advertising and high-margin profit pools; Omnichannel scale and grocery dominance.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: The company reports a net loss, ~Ps. For WMT, walmart's core retail margins are thin, so it depends on enormous volume and on the new high-margin businesses scaling to lift profitability.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick TBBB if you believe its drivers more; WMT if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the TBBB and WMT guides.

TBBB. The gap between ~36% revenue growth and a reported loss is mostly non-cash share-based payment expense, which jumped to ~Ps. 722 million in the first quarter of 2026 from ~Ps. 213 million a year earlier. Store count reached ~3,469 units after ~123 net openings in the quarter and ~580 over twelve months. The valuation prices continued unit expansion rather than current earnings, and the next scheduled report is late August 2026.

WMT. Walmart trades at a historically high P/E for a retailer, reflecting the market's enthusiasm for its higher-margin advertising, marketplace, and membership businesses layered on a defensive grocery base. The thin core margin means earnings growth depends heavily on these new profit pools scaling. Walmart is valued as a quality, recession-resilient compounder rather than a pure low-margin retailer.

Headline figures (approximate, August 2026): TBBB shows revenue (ttm) ~Ps. 83.9 billion (roughly ~$4.5 billion), revenue growth (ttm) ~36%, q1 2026 revenue / same-store sales ~Ps. 22.9 billion, up ~33%; same-store sales ~+16.0%, gross margin (ttm) ~16.2%; WMT shows revenue (ttm) ~$680 billion, operating margin ~4-4.5% (thin, by design), net income (ttm) ~$17-20 billion, eps (ttm) ~$2.30-2.60 adjusted.

TBBB and WMT are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme.
