Question: who believes you need a consumer survey to figure this stuff out? Not me. Waste of time and money. I deleted the survey. You should too.
Amazon just blocked Grok’s shopping bots. People found their bots stopped at Amazon’s door with a short message. It said that “continued access by an unauthorized AI agent” breaks Amazon’s rules.
Elon Musk’s answer was quick. On October 15, he posted, “Maybe we should start a competitor to Amazon?”
That’s all he said. There’s no plan, no timeline and no product. So let’s treat it the way he posted it. It’s an idea. But it’s a bold one, and on paper it’s a smart one. So I ran it through a stress test.
Every big plan rests on a few things that have to be true. If one of them breaks, the plan breaks with it. Let’s find the one most likely to break.
The idea, said fairly
Musk didn’t just get mad at Amazon. He pointed to a way around it.
He told people to “just ask Grok to buy what you want someplace else and get a better deal.” He added, “There are far more purchasing websites than just Amazon!”
A few days earlier, he said Grok had already bought his Lego straight from Lego’s own website.
Credit where it’s due. Grok is already on phones, on X and in Teslas. That’s a front door millions of people walk through every day. Most new shopping ideas have to fight for that kind of reach. Musk already has it.
What has to be true
Here are the four things this idea needs.
People want a bot that shops for them. Not just one that finds things. One that actually buys.
Enough stores let the bots in. If the stores close their doors, the bot has nowhere to shop.
Orders show up on time, like Prime. People got used to fast shipping. They won’t go back.
When something goes wrong, someone makes it right. A bad order or a leaked card can’t just be the shopper’s problem.
Musk already moved on number four. He said SpaceX will pay you back if Grok messes up an order or leaks your card details. That’s a strong move. It takes a big fear off the table.
Most of these look solid. One of them doesn’t.
Start from what’s actually true
Here’s the plain truth under all of this. Every store is built to look out for itself. Not for you.
That sounds harsh, but it’s just how stores work. Each one sets its own shipping. Each one has its own return rules. Each one has its own ways to fail. When a bot shops across five stores, it doesn’t get one simple trip. It gets five sets of rules stacked on top of each other.
I ran this idea through Venture Proof. Here’s what came back.
Today, buying across stores costs about $770 for each round of shopping, once you count all the time, steps and mistakes. The lowest it could cost is about $7. That’s the study’s own estimate, not a final number. But even if it’s off by a lot, the point stands. There’s a huge amount of waste to cut. That’s a big prize, and it’s why Musk’s idea is worth taking seriously.
The one that may break
Here’s the catch. The stores decide if the bot gets in.
Amazon already said no. It’s been setting rules for AI agents since March. It blocked another big company’s shopping bot in September. Now it’s blocking Grok.
Other stores may say no too. Why? Because a shopping bot can look like a new middleman. It stands between the store and the shopper. And stores don’t like a new middleman taking a cut of their sales.
So the second thing on our list, “enough stores let the bots in,” is the one that could break the whole idea. You can have the best bot in the world. If the doors are shut, it can’t buy anything.
There’s a second thing to watch. It’s trust. Bain & Company found that about half of shoppers are wary of letting a bot buy things on its own from start to finish. Musk’s payback promise helps here. But it doesn’t fix it all.
Take something away instead
Most people’s first thought would be to build a new Amazon. New warehouses. New trucks. A new store.
That’s the hard way, and it’s the slow way. It also puts you right up against Amazon’s biggest strength.
So what if Musk took something away instead of adding more?
Don’t build a new Amazon. No new warehouses and no new store.
Borrow what already exists. Lots of stores and delivery networks already want more traffic. Send it to them.
Give shoppers a clear yes button. Before every buy, the shopper says yes. Then the bot buys.
The yes button does two jobs. It helps with trust, because the shopper stays in charge. It also helps with stores, because the bot looks less like a middleman and more like a customer who already decided.
That’s the move. Don’t fight Amazon on its own ground. Bring stores a flood of ready buyers and let them keep doing what they’re good at.
What a full Venture Proof analysis gives you
Venture Proof is a powerful, disruptive strategy-as-code engine. It builds and tests your strategy with code, so every step runs the same way and can be checked.
Here’s what a full analysis gave me on this one idea:
The true cost. Buying across stores costs about $770 today for each round of shopping. The lowest it could cost is about $7.
What to remove. Skip the new warehouses and the new store. Borrow partner networks that already exist. Cut the extra steps down to one clear yes from the shopper.
A plan in stages. First, test it by hand. Second, build what’s hard to copy. Third, automate what worked. Fourth, grow. About a month for each stage.
A tough review. The idea passed with 92 out of 100. The review raised seven hard challenges. None of them held up.
Venture Proof is in private Alpha. I only run it through my advisory work, so spots are few.
The payoff
Musk’s idea works if stores open their doors. That’s the thing to test first, before anyone builds anything big.
He has the reach. He has the payback promise. He has a bot people already use. What he needs is proof that enough stores will say yes.
If you’re on Musk’s team, or you’re making a bet like this one, let’s talk before it’s locked in.
