DoorDash agreed on October 29, 2026 to acquire Instacart for about $17 billion, or $65 per share, a premium of roughly 25% to 26% to Instacart's October 22 close, in a cash-and-stock deal with both boards approving and the Instacart brand kept separate. Coverage has focused on what DoorDash is really buying: advertising and enterprise software make up 30% of Instacart's revenue. On October 30, NYC Mayor Zoran Mamdani publicly opposed the deal, citing DoorDash's $131.5 million wage settlement. How that opposition affects the transaction, and what the combined scale means for grocers and rivals, remains open.
