The thesis

Maplebear, the parent of Instacart, looks more likely to lag the S&P 500 than lead it over the next three months. DoorDash's signed $65.00-a-share offer caps the gain. An antitrust review that the companies expect to run to late 2027 or the first half of 2028 sets the timing. The first federal step on the merger filing, either a cleared waiting period or a request for more information, settles the case.

The shares closed at $58.87 on 11 November 2026, below the $65.00 offer. The market is pricing a long wait and a real chance that regulators block the deal. Searches of news coverage through 12 November 2026 found no report of a Hart-Scott-Rodino (HSR) filing date, a second request or a lawsuit. Company news since 6 November 2026 covers only commercial items, such as the Provi beverage-restocking partnership announced on 12 November 2026.

The rating is Low because the most likely path over 63 sessions is a price held below $65.00 with no regulatory decision. That path gives the shares little room to beat a rising index. A regulatory surprise in either direction would move the shares far more than any grocery result.

Bullish and bearish views on Maplebear Inc.

The bull case on Maplebear Inc. (CART), in brief: the price is fixed and mostly cash. The bear case: closing could take two years.

Bull case

• The price is fixed and mostly cash. Holders can choose $65.00 in cash, 0.3372 DoorDash shares, or $48.75 in cash plus 0.0843 DoorDash shares, according to the 29 October 2026 announcement and Maplebear's Form 425. Stock is capped at 25% of total consideration, and the companies put the premium at 26% over the 22 October 2026 close.
• DoorDash pays heavily if regulators block it. DoorDash's 8-K dated 28 October 2026 says it owes Instacart $1.25 billion if the deal ends over unmet antitrust conditions or a final antitrust court order. Instacart's own break fee is $650 million, payable in specified cases such as a superior proposal.
• Financing and part of the vote are lined up. The deal has no financing condition, and DoorDash's 29 October 2026 release cites a 364-day bridge loan of up to $13.0 billion from JPMorgan Chase. Holders of about 19% of Instacart's voting power signed agreements to vote in favor, per the 8-K.
• The standalone business is growing. Instacart's 10-Q for the quarter ended 30 September 2026 shows gross transaction value (GTV, the total value of orders) up 15% to $10,528M and revenue of $1.09B against $939.00M a year earlier. Net income rose 2% to $147M, and the quarter included $231M of share repurchases.
• The buyer is in strong shape. DoorDash reported third-quarter revenue of about $4.6 billion, up 34%, and net income of $466 million, up 91%, in its 29 October 2026 release. It targets at least $500 million of annual net synergies over several years.

Bear case

• Closing could take two years. The companies expect to close at the end of 2027 or in the first half of 2028. DoorDash's 8-K sets an outside date of 28 October 2027, with up to four automatic three-month extensions if only antitrust approvals remain. Approvals are needed in the US, Canada and Israel.
• An in-depth review looks likely. MLex reported on 30 October 2026 that the deal is likely to draw in-depth federal and state antitrust investigations. Reuters reported that the deal may draw Federal Trade Commission (FTC) scrutiny amid cost-of-living concerns. DoorDash's 2021 talks to buy Instacart collapsed partly over antitrust concerns, per TIKR.
• The FTC is already examining pricing. On 28 October 2026 the FTC sent information orders on personalized pricing and pay-setting to nine companies, including DoorDash and Instacart, per Reuters and TIKR. The inquiry is separate from the merger, but it covers practices a merger review would also examine. The agency proposed a personalized-pricing enforcement policy on 19 August 2026.
• Advocacy groups want the deal blocked. The American Economic Liberties Project and Groundwork Collaborative urged the FTC on 29 October 2026 to block the merger. The first group also called on state attorneys general to act.
• Executives sold near the high. SEC Form 4 filings show CEO Chris Rogers sold 24,665 shares at $60.00 on 26 October 2026 and 24,060 at $55.04 on 23 October 2026. CFO Emily Reuter sold 50,000 at $55.00 on 23 October 2026. All of the sales were under pre-arranged Rule 10b5-1 plans.

Price setup

The $65.00 offer is the ceiling the case turns on. Since the deal was signed, the shares have traded in a narrow band below it. Adjusted daily closes show $59.22 on 4 November 2026, $57.79 on 5 November 2026 and $58.87 on 11 November 2026. The 52-week intraday high of $62.00 came on 26 October 2026, the day of the CEO's plan sale at $60.00. The last close is 5.0% below that high.

The 3-month change is 17.6%, from a $50.08 close on 13 August 2026, and most of that gain is the deal premium. As of 11 November 2026, the 50-day moving average is $50.27 and the 200-day moving average is $44.09. Both sit well under the price, which shows how far the shares have moved from where they traded before the deal. The 52-week closing low is $32.93, set on 11 February 2026. If the deal were blocked, the moving averages would be a better guide to standalone value than the offer.

The third-quarter report came on 29 October 2026, so no quarterly report falls in the next 30 days. The 10-Q counts 236,630,090 shares outstanding on 30 October 2026. That count includes the 5,833,333 shares from the 25 September 2026 preferred conversion.

Catalysts ahead

• ~21 November 2026 (est.): Reported close of the comment period on the FTC's proposed personalized-pricing policy; the FTC's own page gave 18 September 2026. Shows how far the agency's pricing concerns reach before it acts on the merger, since pricing is central to criticism of the deal.
• ~12 December 2026 (est.): First responses due to the FTC's 28 October 2026 information orders, 45 days after receipt. Puts Instacart's and DoorDash's pricing and pay practices in front of the agency that may also review the merger.
• 28 October 2027: Outside date under the DoorDash merger agreement. Marks when either side may end the deal; automatic three-month extensions apply only if antitrust approvals are the sole open condition.

What would change the view

A daily close above $65.93, above DoorDash's $65.00 offer, which would show the market pricing a higher or competing bid and the shares leading the S&P 500; a superior proposal from another buyer would also prove the call wrong.

What it trades with

The shares now trade on deal odds more than on grocery delivery results. Because of the fixed $65.00 ceiling, a broad market rally adds little, and a broad decline should also move the shares less than the index. A run of closes that track the S&P 500 on days without deal news would contradict that view. The six sessions from 4 November to 11 November 2026 are too few to measure it.

DoorDash is the one direct link. The 0.3372-share stock election ties part of the payout to DoorDash's share price, and stock can make up as much as 25% of consideration. Uber's delivery arm is the competitor to watch in the review. Benzinga reported strong Delivery growth in Uber's third-quarter results on 5 November 2026, which the merging companies could cite as evidence that competition continues.
