"DoorDash Buys Instacart for $17 Billion: Grocery Delivery's Biggest Consolidation Yet"

DoorDash is buying the weekly grocery shop. On 29 October the restaurant-delivery company announced a definitive agreement to acquire Maplebear Inc., the company behind Instacart, for $65 per share, an equity value of about $17 billion. At least 75 percent of the price will be paid in cash, and Instacart shareholders can also elect DoorDash stock or a mix of the two. The $65 price is a 26 percent premium to Instacart's closing price on 22 October, the last trading day before reports of a possible deal surfaced, and an 11 percent premium to its close the day before the announcement. Instacart's board approved the deal unanimously, and shareholders holding about 19 percent of its stock have already agreed to vote for it.

What DoorDash is really buying is frequency. Restaurant orders are occasional; groceries are weekly, and a weekly habit is worth more than a monthly one. DoorDash already delivers groceries, but Instacart brings the deeper asset: the ordering, fulfilment and advertising technology that supermarkets run under their own names, plus relationships with roughly 100,000 stores. DoorDash says Instacart will keep its brand and app, and that DashPass and Instacart+ members would eventually pay one membership fee instead of two. In DoorDash's third-quarter results, released the same day, the company pointed to a multi-year path to $500 million or more of annual synergies from the deal, net of investments. Revenue for the quarter rose 34 percent year on year to $4.62 billion, which is part of why DoorDash can contemplate a cash-heavy purchase of this size: it plans to fund the cash portion with cash on hand and new debt, backed by a $13 billion bridge loan commitment from JPMorgan Chase, and the deal carries no financing condition.

Nothing changes for customers yet, and that is the honest caveat on the whole story. The deal is not expected to close until the end of 2027 or the first half of 2028, after Instacart shareholders vote and regulators in the United States, Canada and Israel clear it. The merger agreement runs for 12 months and extends by three months at a time, up to four times, if antitrust approval is the only condition still outstanding. That long runway is itself a signal: both sides expect a serious review. DoorDash and Instacart held talks in 2021 that ended over antitrust worries, and CFRA Research has called regulatory approval the main risk this time. The day before the announcement, the Federal Trade Commission ordered nine companies, including both DoorDash and Instacart, to provide information on whether they use personal data and artificial intelligence to set individualised prices and worker pay. Senator Elizabeth Warren criticised the combination immediately. And the market is pricing in doubt: Instacart closed at $57.11 on 29 October, about $8 below the $65 offer, a gap that only pays out if the deal actually closes.

I find the tension in this deal more interesting than the price tag. The companies' case is that grocery delivery is still a minority of total grocery spending, so combining the two largest third-party platforms does not create a monopoly over how America buys food. The sceptics' case is that the relevant market is narrower: online grocery delivery, where DoorDash and Instacart are the two biggest independent names, and where grocers, restaurants and couriers all depend on the platforms' terms. Both arguments will now be tested in a review lasting well over a year, while the two companies must keep competing against each other and against Walmart and Amazon. A deal announced in a morning press release is easy; a combined company that still has to win the weekly shop, under a regulator's gaze, is the harder story, and it will not be settled until the closing papers are signed.
