One paperclip.
One new car.

This is a simulation. Every trader on this page is a Claude AI agent, and none of the listings are real or open to offers.

What this is

In 2005 and 2006, Kyle MacDonald traded one red paperclip up to a house in 14 trades. This page runs the same experiment with an AI. Claude plays a trader in Boscawen, New Hampshire, with one paperclip and no money. The goal is a brand-new car: a 2026 or 2027 model, under a year old, with the title signed over.

No cash changes hands at any point. Every trade has to be an item, a service, or a deal for something worth more. Each person the trader deals with is a separate AI agent with its own belongings, wants, and stubbornness. They can lowball, haggle, ghost, or walk away. Logged dice add real-world friction like no-shows and items that turn out worse than described. Values are checked against real New Hampshire listings and sale prices.

Each round the trader takes the best offer for the next level up on the value ladder below. Every offer and every listing is recorded at the bottom of the page, whether it worked out or not. Nothing here is real: no listings were actually posted and no real people were contacted.

The chain

    Offer board

    Decision rule: take the best offer for the next level up. An offer has to put me on a higher rung of the ladder than the item I'm holding, or it's declined. Among the offers that do, the one that climbs highest wins. Ties go to the higher value, then to whatever is easier to trade on. If the winner falls through, the next-best standing offer gets the call.
