CART · Maplebear Inc.

The thesis

Maplebear, which runs Instacart, now trades on a takeover rumour more than on its grocery business. The case for the shares beating the market over three months is weaker than the 23 October 2026 jump suggests, because one of the two named suitors has reportedly walked away and the other has failed antitrust review on this exact deal before. The 5 November 2026 third-quarter report and any confirmed bid settle it.

The Information reported on 23 October 2026 that Instacart is working with an investment bank and held preliminary talks with DoorDash and Uber. The shares closed up $4.76, or 9.21%, at $56.44 that day, according to 24/7 Wall St. That close is the highest in a year in adjusted daily closes. Bloomberg, citing people familiar with the matter, reported the same day that the Uber talks have ended.

The narrative is accelerating: the sale report on 23 October 2026 brought new attention and a one-day gain of more than 9%. The business underneath is growing steadily, and that growth was priced before the rumour.

Bullish and bearish views on Maplebear Inc.

The bull case on Maplebear Inc. (CART), in brief: The core business is compounding steadily. The bear case: One of two suitors is already gone.

Bull case

• The core business is compounding steadily. In the 6 August 2026 second-quarter release, gross transaction value (GTV, the total value of orders) rose 14% to $10,351M. Orders rose 9% to 90.3M and adjusted EBITDA (earnings before interest, taxes, depreciation and amortization, adjusted) rose 19% to $313M.
• Guidance points to more of the same. The company guided third-quarter GTV to $10,300M–$10,550M and adjusted EBITDA to $320M–$340M in its 6 August 2026 release. A clean beat on 5 November 2026 would support the price without a deal.
• Buybacks shrink the share count. Instacart repurchased $325M of stock in the second quarter of 2026. It said it expects to return most of its 2026 free cash flow through repurchases.
• A formal process can draw more bidders. The Information reported on 23 October 2026 that an investment bank is advising the company. Analysts cited by 24/7 Wall St. on 24 October 2026 put a typical 30%–40% premium at roughly $16B–$17B in equity value, against a market value of about $12B.

Bear case

• One of two suitors is already gone. Bloomberg reported on 23 October 2026 that Instacart approached Uber in recent weeks and those talks have ended. Uber has other deals pending: it agreed to buy ezCater for $2.3B in cash on 6 October 2026, and its offer for Delivery Hero runs through 5 November 2026.
• DoorDash faces the antitrust problem that sank the 2021 talks. DoorDash and Instacart discussed a deal in 2021 that could have valued Instacart at $40B–$50B. Those talks collapsed partly over doubts about antitrust approval. The Federal Trade Commission's 2024 suit against Kroger–Albertsons, which won a preliminary injunction in December 2024, shows how closely regulators watch grocery.
• The talks are early and unconfirmed. Instacart, Uber and DoorDash did not comment on 23 October 2026, and no agreement has been announced. If no bid follows, the 23 October 2026 gain can unwind quickly.
• Price already reflects good news. The shares rose 23.7% over three months to the 23 October 2026 close, and the 14-day relative strength index (RSI, a momentum gauge where readings above 70 signal an overbought stock) reached 84.3. The consensus target was about $55.90 per MarketBeat on 20 August 2026, below the last close. Wells Fargo kept an Equal-Weight rating and raised its target to $56 on 5 October 2026.

Price setup

The last close was $56.44 on 23 October 2026, the highest close in a year in adjusted daily closes. 24/7 Wall St. puts the 52-week intraday high at $57.98. The shares gained $4.76 in one session on the sale report. That gain now rests on reporting, not on a filed offer.

Crowding is visible. An RSI of 84.3 is extreme. The three-month gain of 23.7% leaves the price far above where it traded in late July. Earnings arrive on 5 November 2026, 11 days after the close. On 25 September 2026 the company issued 5,833,333 common shares when it converted and eliminated its Series A preferred stock. That conversion simplifies the capital structure; it was not a sale of new stock into strength.

Catalysts, next 30 days

• 5 November 2026, after market close: third-quarter 2026 results, with a call at 5:00 p.m. Eastern. The company confirmed the date on 14 October 2026. Management may be asked about the sale process. Results are measured against GTV guidance of $10,300M–$10,550M and adjusted EBITDA guidance of $320M–$340M.
• 5 November 2026: Uber's Delivery Hero tender offer period ends. The outcome shows how much deal capacity Uber has left, though Uber has reportedly left the Instacart talks.
• Undated: any formal bid, a statement from Instacart on strategic options, or reports of other bidders.

What would change the view

A confirmed bid would break the cautious case. A filed offer from DoorDash or a new party at a clear premium, with a credible antitrust plan, would make the shares a deal-spread stock anchored to the offer price. A third-quarter beat with GTV growth above 14% and higher full-year guidance would also strengthen the standalone case.

The case for the shares fails outright on a daily close below $51. At that level the 23 October 2026 gain of $4.76 would be erased, which would show the market no longer prices a deal. A report that the DoorDash talks have ended, or a GTV miss against guidance on 5 November 2026, would weaken the case further.

What it trades with

On 23 October 2026, the day of the report, DoorDash shares fell 3.5% and Uber shares fell 3.4%. In the near term, Maplebear trades against its would-be buyers. Deal news moves the three in opposite directions, while grocery-delivery demand moves them together.

The shares sit in a group of mid-cap software and internet names trading on takeover or strategic-review news, alongside Braze, PTC, Klaviyo, DXC Technology and Bumble. That group has seen more such news since mid-October 2026. A string of deals failing or being withdrawn in the group would raise the bar for an Instacart premium to hold.
