The next platform war isn't about who delivers your dinner. It's about who AI chooses to deliver it.
I've been waiting for the next move since DoorDash agreed to acquire Instacart for $17 billion. On November 5, it came.
Amazon replaced Grubhub with Uber Eats as its Prime restaurant-delivery partner. The same day, Lyft launched a membership with DoorDash, connecting ride rewards with food delivery.
Uber had reportedly discussed buying Instacart too. Those talks broke off. Soon after, Uber Eats was inside Prime.
Two strategies are taking shape. DoorDash is buying its way into a broader ecosystem. Uber is partnering its way into one.
Everyone wants to be the one-stop shop. Even Walmart, the country's biggest grocer, now offers delivery from Subway, Dunkin' and Papa Johns in select locations, with Express delivery in as little as 30 minutes.
For years, winning that race meant being the app you open when you're hungry, out of groceries or need a ride.
What happens when consumers stop opening apps?
Imagine telling your AI assistant: "Order dinner for four, we're out of soy milk, and book me a ride for 7."
You haven't chosen Uber Eats, DoorDash, Instacart or Lyft.
You've expressed a need.
Something else decides who fulfills it.
This isn't hypothetical. Instacart was the first grocery app to offer shopping and checkout inside ChatGPT. Google's Gemini already builds DoorDash and Uber Eats orders on supported newer Android phones.
The telling part: the platforms see it coming. DoorDash built its own text-to-order agent. Amazon has restricted outside shopping agents. Uber is pursuing distribution across AI assistants as well as Amazon itself.
So what wins in agentic commerce: owning the ecosystem, partnering into one, or becoming the platform the AI prefers?
My bet: the platform that holds what the AI needs. Your memberships, your saved card, your order history.
& why it matters
Brands used to compete for attention. Now they may be competing for an AI’s decision.
And the unit of competition is no longer the category. It’s the need.
When AI becomes the interface, who really owns the customer relationship?
