## What was Project Deal?
Anthropic created a classified-ads marketplace where **Claude agents** negotiated on behalf of buyers and sellers.

- **69** Anthropic employees took part.
- Each had a **$100** budget, paid out as a gift card.

## Results
- **186** deals were made.
- Total transaction value was "just over $4,000."

## Opus vs. Haiku
| | Result |
|---|---|
| Deals | Opus completed about 2.07 more deals |
| Selling | Opus sellers got about $2.68 more per item |
| Buying | Opus buyers paid about $2.45 less |

Example: a broken folding bike sold for **$38** through a Haiku agent and **$65** through an Opus agent.

Anthropic called it "a pilot experiment with a self-selected participant pool."
