DoorDash’s $17 Billion Bid for Instacart Sets Up an Antitrust Fight and a Clash With New York City
Key points
- DoorDash agreed to buy Instacart at $65 per share, roughly $17 billion in equity value and a 26% premium to its October 22 close, with at least 75% paid in cash 5.
- The deal needs Instacart shareholder approval, Hart-Scott-Rodino clearance and sign-off in Canada and Israel, with closing targeted for late 2027 or the first half of 2028 5.
- Consumer Edge data cited in reporting put DoorDash at 59% of U.S. delivery platform spending and Instacart at 18%, so the combination would control more than three-quarters of that market 6.
- New York City Mayor Zohran Mamdani and the Department of Consumer and Worker Protection (DCWP) criticized the deal, and Commissioner Samuel A.A. Levine said worker rights will be enforced whether or not it proceeds 1 2.
What DoorDash Is Paying
DoorDash and Instacart (legally Maplebear Inc.) announced a definitive agreement under which DoorDash will pay $65 per share, an equity value of about $17 billion. That is a 26% premium to Instacart’s closing price on October 22, 2026, the last trading day before media reports of talks 5. Instacart’s board approved the deal unanimously, and holders of about 19% of shares have agreed to vote in favor 5.
Shareholders can elect $65 in cash, 0.3372 DoorDash shares, or a mix of $48.75 in cash and 0.0843 shares. Stock is capped at 25% of the total, with proration if elections exceed that 5. DoorDash plans to fund the cash portion with cash on hand and debt, backed by a 364-day bridge loan commitment from JPMorgan Chase. It says the deal has no financing condition and that it is aiming to preserve investment-grade ratings 5.
The price is a sobering one for Instacart. Private investors valued it at $39 billion in 2021, and its 2023 IPO valued it at about $10 billion. It has never traded above roughly $14 billion on the public market 6. Instacart’s third quarter showed gross transaction value up 15% and revenue up 17%, but it suspended guidance and canceled its planned November 5 earnings call after the announcement 3.
The Grocery Strategy
DoorDash built its name on restaurant and takeout delivery. Instacart brings grocery retailer relationships, shopping expertise, an advertising business and enterprise technology that powers grocers’ own websites 4 6. Tony Xu, DoorDash’s CEO, framed the pitch as giving stores of every size tools that the largest online retailers build for themselves 5.
The companies promise consumers access to more than 50,000 additional stores on top of Instacart’s nearly 100,000, and a single membership in place of separate DashPass and Instacart+ fees, which they estimate would save $100 million a year 5. Those figures are DoorDash projections, not independently validated 3. Post-close commitments include no grocery exclusivity and letting Instacart shoppers choose whether to take DoorDash orders. DoorDash expects to keep Instacart’s brand, app and enterprise products 5.
Scale tells the rest of the story. DoorDash operates in 40 countries, handled more than three billion orders last year and relies on about nine million couriers. Instacart processed 338 million orders with 600,000 shoppers 6.
The Antitrust Hurdle
The approval list includes Instacart shareholders, expiry of the Hart-Scott-Rodino waiting period, and regulators in Canada and Israel 5. Reporting notes the two companies discussed a merger in 2021, but those talks collapsed over antitrust concerns 6. An independent report on Instacart’s sale process had also anticipated scrutiny for a DoorDash or Uber combination 3.
The market-share math is the core issue. Consumer Edge figures reported by NBC News give DoorDash 59% of U.S. delivery platform spending and Instacart 18%, against just under 20% for Uber Eats 6. DoorDash is expected to argue that the true market is far broader, since in grocery it competes with Walmart and Amazon‘s own delivery. Walmart also uses Instacart today, and the future of that relationship is unclear 6. Regulators will probe whether a merged platform could gain leverage over merchant commissions, consumer fees and contract terms 4.
New York Pushes Back
City officials reacted within hours. Mayor Zohran Mamdani wrote on X that corporate consolidation means higher prices, harsher exploitation and greater inequality, adding that the city’s fight with these giants does not stop now 2. Xu countered that the deal would bring lower prices, faster delivery and more earnings for gig workers 2.
DCWP Commissioner Samuel A.A. Levine called the merger part of a troubling trend of consolidation that divides workers and consumers, and said the city will fully enforce delivery workers’ rights whether or not it goes ahead. He added that the agency has no tolerance for corporate shell games meant to evade accountability 1. The city has leverage and history here: last month DoorDash agreed to pay $131.5 million to end an investigation into how it paid delivery workers, with some money returned to workers 2.
For now, little changes for workers. Instacart told shoppers the companies stay separate until closing, with no immediate change to how they accept or deliver orders 3. With a closing window that runs into 2028, regulators, retailers and city enforcers have a long runway to shape the outcome.
Companies mentioned: Uber (UBER $65.74 ▲0.7%) • Amazon (AMZN $243.79 ▼4.2%)
