Instacartの収益モデルについて、The Shelby Report (independent grocery-industry trade publication)公式のtrade-press news article reporting on Instacart's Q1 2026 earnings release, published by an independent grocery-industry trade publication (not Instacart's own press release)（https://theshelbyreport.com/2026/05/07/instacart-reaches-1b-in-total-revenue-for-first-time/）で確認できます。The entity's existing References describe what Instacart does (grocery delivery/ordering) and its stock market valuation, but never explain that a large share of its revenue and profitability comes from advertising/retail media rather than delivery/service fees - this is a genuinely new business-model/differentiator angle.具体的には「In Q1 2026, Instacart's advertising and other revenue grew 16% year-over-year to $286 million, representing roughly 28% of the company's $1.02 billion total quarterly revenue and about 2.8% of its $10.29 billion gross transaction value (GTV) for the quarter - showing advertising is a substantial and growing part of Instacart's business model beyond delivery fees.」といった記載が確認できます。限界として、収益区分・課金体系は決算期や製品改定により変わりうるため、この内容は開示時点のものです。 This reflects a single quarter (Q1 2026) snapshot; advertising revenue as a share of GTV/total revenue can fluctuate quarter to quarter, so these percentages should not be read as a fixed, permanent ratio. The article is trade-press reporting on the company's own earnings release rather than fully independent financial analysis.Current Statusとして、2026年08月23日に当該Sourceを取得し、上記の内容を確認しました。Source種別としては、これは第三者であるThe Shelby Report (independent grocery-industry trade publication)による報道であり、企業の自己申告とは性質が異なりますが、報道時点の取材内容に基づくものです。
