Competitive Pressure Mounts: Amazon-Uber Eats Deal and Instacart Uncertainty Weigh on DoorDash

What happened

DoorDash shares are under renewed pressure after reports that Amazon has struck a delivery partnership with Uber Eats and that Instacart may be involved in acquisition plans, raising doubts about DoorDash's ability to defend its local-commerce leadership. The WSJ highlights that shareholders are unconvinced the company can take on Amazon, aligning with our prior concern that margin expansion has stalled. In Q2 2026, DoorDash grew orders 27% to 970 million and GOV 36% to $33.1 billion, but net revenue margin remained flat at 13.5% and GAAP net income fell 30% YoY to $200 million. The stock has already corrected from its August peak above $236 to around $200, but at 103x P/E and 51x EV/EBITDA it still prices in durable multi-engine growth. The new competitive threat adds to regulatory and litigation friction, making it harder for management to deliver the profit-density improvement needed to justify valuation.

Implication

Short-term, the Amazon-Uber Eats deal could intensify grocery and retail competition, pressuring DoorDash's ability to raise take rates without losing share, while Instacart-related uncertainty may distract management and delay ad monetization progress. Long-term investors should watch whether DoorDash can leverage its DashPass membership base (75% of U.S. grocery/retail orders) to offset competitive encroachment, but the flat net revenue margin and declining GAAP profitability suggest that density hasn't yet converted into pricing power. A sustained pullback below $175 would offer a more attractive risk/reward, but even then, position sizing should be modest given SBC dilution and litigation overhangs. Until management provides concrete evidence that ads, grocery mix, and fee updates are lifting net revenue margin above 14% without slowing order growth, we see no reason to rush into the stock. Conversely, if management effectively navigates these competitive and strategic challenges and shows accelerating profit density, the thesis could turn positive.

Thesis delta

The core WAIT thesis remains intact: strong top-line growth is not yet translating into higher net revenue margin or GAAP earnings, and the stock already reflects optimistic assumptions. The Amazon-Uber Eats partnership and Instacart uncertainty add a new competitive layer that increases the probability of the bear case (order growth below 20% and margin stagnation) from 25% to 30%. We keep our valuation range of $160-$245 with base case $215 unchanged, but the risk/reward skews slightly more negative in the near term.
