您是否觉得好市多的结账队伍比以往任何时候都更长？您不是在想象。根据市场研究公司Placer.ai的一份新报告，(1)自2019年第一季度至2026年第一季度，仓储式零售商的购物次数增加了18.1%。
在会员共享受到限制(2)、会员价格上涨(3)以及连锁店向公众关闭食品店(4)的情况下，还出现了一段时间。因此，客流量有所增加，但数据还表明好市大的客户群也扩大了。在致Moneywise的一封电子邮件中，Placer.ai的(5)研究主管伊丽莎白·拉丰坦（Elizabeth Lafontaine）将零售商的重点放在更低的价格、更高的质量和成为“一站式商店”归因于增长。
“好市大已经将店内体验的重点放在满足购物者的需求上，这增加了忠诚度并吸引了新的、更年轻的会员，”拉丰坦告诉Moneywise。

好市大的会员增长正值许多美国人正在寻找降低成本的方法之时。所有商品消费者价格指数（CPI）在3月份上涨了1%（6），比上一年上涨了3.3%。与此同时，食品价格也在3月份上涨，尽管略有上涨，比2月份上涨0.1%，但比去年上涨了2.7%。
最近，消费者报告调查了哪些大型零售商为消费者提供了比全国平均水平更好的食品价值，沃尔玛和好市大名列前茅，分别比全国平均水平低21.4%（7）。这种节省可能有助于解释为什么尽管该计划的成本现在更高，会员人数仍在增加。2024年9月，仓储式零售商将（8）黄金会员的价格从60美元上调至65美元，而行政会员等级则从120美元上调至130美元。
正如《华尔街日报》（The Street）报道（9），在零售商最近的第二季度财报电话会议上，CFO加里·米勒奇普（Gary Millerchip）报告称，行政会员人数比去年增长了9.5%，总共有4040万会员，而总会员人数已达到8210万，比2025年第二季度增长了4.8%。
“通过提高‘承诺成本’，Placer.ai（10）分析师莉拉·玛格利特（Lila Margalit）写道，“好市大可能会阻止休闲或机会性用户，同时加深那些计算过数字并更频繁地购物以证明费用的购物者的参与度。”
四大领先AI模型讨论这篇文章
"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.
