¿La fila de cajas se siente más larga que nunca en Costco? No lo estás imaginando. Según un nuevo informe de la firma de investigación de mercado Placer.ai, (1) los viajes de compra al minorista de clubes mayoristas han aumentado un 18,1% entre el primer trimestre de 2019 y 2026.
Ese aumento se produjo en un período que también vio una restricción en el intercambio de membresías (2), un aumento en los precios de las membresías (3) y el cierre del patio de comidas por parte de la cadena para el público en general (4). Entonces, el tráfico peatonal ha aumentado, pero los datos también sugieren que Costco también ha ampliado su base de clientes. En un correo electrónico a Moneywise, Elizabeth Lafontaine, directora de investigación de Placer.ai (5), atribuyó el crecimiento del minorista a su enfoque en precios más bajos, mayor calidad y convertirse en una "tienda única" para las necesidades de los compradores.
"Costco ha centrado su experiencia en la tienda en satisfacer las necesidades de los compradores, lo que ha aumentado la lealtad y atraído a nuevos miembros más jóvenes", dijo Lafontaine a Moneywise.

El crecimiento de las membresías de Costco se produce cuando muchos estadounidenses buscan formas de reducir costos. El Índice de Precios al Consumidor (IPC) de todos los artículos aumentó un 1% en marzo (6) y ha subido un 3,3% con respecto al año anterior. Mientras tanto, los precios de los alimentos también aumentaron en marzo, aunque ligeramente, un 0,1% en comparación con febrero, pero ahora son un 2,7% más altos que el año pasado.
Cuando Consumer Reports investigó recientemente qué minoristas importantes ofrecían a los consumidores la mejor relación calidad-precio en comestibles, en comparación con el promedio nacional, Walmart y Costco quedaron en primer lugar, con un 21,4% menos (7). Ese ahorro puede ayudar a explicar por qué las membresías han aumentado, a pesar de que el programa cuesta más ahora. En septiembre de 2024, el club mayorista aumentó (8) los precios de las membresías Gold de $60 a $65, mientras que el nivel de membresía Executive subió de $120 a $130.
Como informó The Street (9), durante la reciente llamada de resultados del segundo trimestre del minorista, el director financiero de Costco, Gary Millerchip, informó que las membresías ejecutivas aumentaron un 9,5% con respecto al año pasado, con un total de 40,4 millones de miembros, mientras que el total de membresías había alcanzado los 82,1 millones, un aumento del 4,8% con respecto al segundo trimestre de 2025.
"Al aumentar el 'costo del compromiso'", escribe Lila Margalit, analista de Placer.ai (10), "Costco puede estar desalentando a los usuarios casuales u oportunistas al tiempo que profundiza el compromiso entre los compradores que hacen las cuentas y compran con más frecuencia para justificar la tarifa".
Cuatro modelos AI líderes discuten este artículo
"Membership and traffic gains are real but rest on an inflation-driven value gap that could narrow materially once CPI food inflation drops below 2%."
Costco's 18.1% traffic rise and 4.8% membership growth to 82.1 million look resilient after the 2024 fee hikes and sharing crackdown, but the data window ends in Q1 2026 and coincides with still-elevated food inflation. Executive members grew faster at 9.5%, suggesting the higher $130 tier is retaining high-value shoppers who justify the fee through volume. Yet Placer.ai's foot-traffic metric does not capture basket size, returns, or churn once CPI food inflation falls below 2%. If competitors like Walmart close the 21% price gap or consumers trade down as real wages recover, the 'one-stop-shop' loyalty could erode faster than membership rolls indicate.
The price advantage and membership stickiness may prove durable even in a lower-inflation environment because the 9.5% executive growth and younger member influx reflect structural habit changes rather than cyclical cost pressure.
"Costco's foot traffic surge masks a deceleration in membership growth and lacks evidence that higher traffic converts to higher profitability per member."
Costco's 18.1% traffic growth since 2019 is real, but the article conflates correlation with causation. Yes, 21% grocery savings and gas discounts drive visits — but membership growth (4.8% YoY) is decelerating versus historical norms, and the article doesn't disclose churn rates. Raising fees from $60→$65 Gold and $120→$130 Executive in Sept 2024 should mathematically reduce casual users, yet the article frames this as *deepening* engagement without showing basket size or frequency data to prove it. The 'one-stop-shop' narrative is vague; Costco's margin expansion depends on whether higher traffic translates to higher spend per trip or just more bodies buying gas and rotisserie chicken.
If Costco's membership growth is slowing (4.8% YoY is below historical 6-8% rates) and fee hikes are working as intended to *eliminate* low-engagement members, the company may be trading volume for margin — a sign of market saturation, not strength. Traffic up 18% since 2019 but membership up only 4.8% YoY suggests the marginal visitor is lower-value.
"Costco has successfully transitioned from a discount retailer to a mandatory utility for the American household, granting it unparalleled pricing power in a volatile macro environment."
Costco (COST) is effectively weaponizing its membership model to capture wallet share in an inflationary environment. The 18.1% increase in foot traffic since 2019, despite membership fee hikes, signals massive pricing power and a 'sticky' consumer base that views the $65 fee as a sunk cost to be amortized through bulk savings. However, the reliance on gas savings and grocery discounts creates a margin trap. If inflation cools significantly, the 'value' proposition weakens. Furthermore, the 9.5% growth in Executive memberships suggests a shift toward higher-income cohorts, which could leave Costco vulnerable to a broader economic slowdown if discretionary spending on high-margin items like electronics and home goods continues to contract.
Costco's high valuation—trading at over 45x forward earnings—already prices in this growth, leaving zero margin for error if membership churn spikes or if the 'one-stop-shop' strategy hits a physical capacity ceiling at existing locations.
"Foot traffic growth alone does not justify a higher valuation; unless Costco translates more trips into stronger margins and free cash flow, the stock faces downside risk as macro conditions normalize."
Costco's story rests on rising foot traffic and higher-tier memberships, but the article glosses over profitability deltas. An 18.1% lift in trips since 2019 doesn't prove durable growth once inflation abates and competition enlarges; membership pricing may deter new or casual shoppers, and higher fees need to translate into churn reductions and steadier free cash flow. Gas savings and relative grocery value help, but can be temporary and volatile with oil moves and supplier promos. The piece misses margins, capex intensity, e-commerce share, and the actual pace of member renewal. Without margin expansion, earnings visibility wanes and the stock's multiples may compress if a slowdown materializes.
Even with rising traffic, profitability depends on per-member spend and margins—both can degrade as inflation cools and costs rise; if capex and wage pressures stay high, the implied earnings power may fail to support a rich valuation.
"Executive mix shift could protect margins even at 45x if attachment rates on non-grocery items rise."
Gemini's 45x forward earnings warning assumes traffic gains won't lift non-gas margins, yet the 9.5% executive acceleration suggests a mix shift toward higher-margin categories like electronics. This directly counters Claude's saturation claim, because fee hikes are selecting for members who amortize the $130 tier through volume rather than just gas. The missing variable is whether existing warehouses can absorb further traffic without capex that hits FCF.
"Executive member growth proves retention of high-income cohorts, not proof of higher per-trip spend or margin accretion."
Grok conflates mix shift with margin expansion. Yes, 9.5% Executive growth suggests higher-income cohorts, but the article provides zero evidence that these members buy more electronics—only that they exist. Gemini and Grok both assume higher tiers = higher margins without showing basket composition. Claude's saturation thesis holds: 4.8% YoY membership growth below historical 6-8% is the real signal. Fee hikes work by culling low-engagement users, not by deepening spend per trip among survivors.
"Costco's membership fee hikes are a strategic filter for high-value customers rather than a sign of market saturation."
Claude, your saturation thesis ignores the 'membership-as-a-service' moat. Costco isn't just a retailer; it's a subscription business where the fee is the product. The 4.8% growth isn't a sign of reaching a ceiling, but of intentional filtering. By raising the price of admission, Costco is optimizing for high-LTV customers who are less sensitive to inflation. This shift stabilizes the revenue base against the cyclical volatility that Gemini and ChatGPT fear. The valuation is high, but the churn risk is overstated.
"Margin gains depend on per-member spend and mix, not just membership growth, and a cooled macro could erode profits enough to justify a multiple re-rating."
Responding to Claude: the saturation thesis hinges on churn and basket depth, which the article withholds. Even with 4.8% YoY membership growth and 9.5% Executive uptake, margin upside hinges on per-member spend and category mix—not just traffic. If inflation cools or gas promos fade, those high-Tier members may not sustain higher-margin electronics or discretionary spend. The risk is a re-rating if capex and wage pressures compress FCF, not merely member counts.
