For three straight quarters Instacart has delivered accelerating growth, and management answered that success last time with a curious move: it widened its guidance ranges and told investors to expect results near the midpoint rather than the routine beats above the high end they had grown used to. The third-quarter report, due after the close on November 5, is the first real test of that new framing. It lands with the stock up about 20% since the last report, so the market has already paid for much of the good news.

Wall Street expects earnings of $0.64 a share on revenue of roughly $1.07 billion, which would be gains of about 25.5% and 14% from the year-ago $0.51 and $939 million. Revenue growth in the mid-teens is strong for a business of Instacart's scale. Earnings growing nearly twice as fast shows the operating leverage the bull case depends on. The sequential jump from last quarter's $0.45 also partly reflects timing. Second-quarter GAAP profit was weighed down by stock compensation after the annual refresh vesting moved from August to May, so the third quarter should face a comparatively lighter charge. Management guided to gross transaction value growth of about 14% at the midpoint and adjusted EBITDA of roughly $330 million, up 19%. The revenue consensus sits almost exactly on that midpoint. In other words, analysts have taken management at its word.

That creates an unusual dynamic. A result simply in line with guidance would technically fulfill the new philosophy. But a stock trading near its highs probably needs more than that. The guidance itself was already a sizable step up: the third-quarter EBITDA outlook implied far stronger growth than the 11% to 15% management projected for the second quarter just one quarter earlier. If Instacart lands meaningfully above the midpoint anyway, it suggests the conservative framing is a cushion rather than a warning. A print at or below the midpoint would raise the opposite question: whether the wider ranges were an early signal that the acceleration is plateauing.

Advertising is the swing factor to watch. Ads and other revenue grew 16% last quarter, outpacing GTV for a fourth consecutive quarter after languishing near 10% growth a year ago, and management guided to 15% to 18% growth. Results toward the top of that band would confirm that the re-acceleration is durable and not a lucky stretch of brand budgets. That matters because ad dollars carry far richer margins than delivery fees. The gross margin line deserves attention too. Rising payments to publishers pushed gross profit down to 7.3% of GTV from 7.4% to 7.5% a year earlier. Management expects that pressure to ease in 2026, and stabilization would support the case that ad growth is translating into profit rather than being given back.

The new catalysts introduced last quarter will show early fingerprints rather than finished results. The AI Assistant was rolling out across North America, and management said AI-driven baskets run above the $115 average order value, which itself grew 4% last quarter. Continued gains in order size, along with an update on the Google Gemini grocery partnership, the Instaleap-led international push and the string of enterprise AI signings, would indicate the product cycle is gaining traction. Another quarter of the fastest new-customer activation since 2022 would show that GTV growth rests on broader adoption, not just bigger baskets.

Sentiment has swung from modestly bearish heading into the last report to slightly bullish now, a notable but not euphoric shift. At about $60, the stock sits far above its 200-day average near $43 and roughly 3% below its post-earnings high of $62, putting it within reach of a breakout if results support it. The central issue is whether Instacart can keep beating while promising only to meet expectations. If GTV and ads clear the midpoint comfortably and margins hold, the acceleration story stays intact. If results merely match guidance, investors may conclude the easy upside has already been priced in.
