Anthropic Project Deal: Claude Agents Trade on Marketplace
Anthropic ran a research experiment called Project Deal in December 2025 that let employee-controlled AI agents (backed by Claude models) buy and sell on a secret internal marketplace. Sixty‑nine employees each had a $100 budget and let their personal agents negotiate and transact inside a Slack channel. The test yielded 186 real deals worth over $4,000 in total, with physical items exchanged. Anthropic ran parallel blind trials comparing model variants (Claude Opus 4.5 vs Claude Haiku 4.5) and found the stronger model produced systematically better economic outcomes (higher sale prices and different buyer behavior). The company highlights implications for agent-driven commerce, model-driven price optimization, and legal/consent questions for agents acting on users’ behalf. The experiment is presented as preliminary research rather than a product launch.
Demonstrates early, practical agent-driven commerce and shows model choice materially affects economic outcomes — relevant to e-commerce, retail media and AI-driven transaction design, though results are preliminary.

Key Takeaways & Evidence Grounding
- Anthropic ran Project Deal in December 2025 with 69 employees participating.
- Each participant had a $100 budget for their personal AI agent; agents transacted inside a Slack-based secret marketplace.
- The experiment resulted in 186 deals with a combined value of over $4,000; bought items were physically exchanged.
- Anthropic compared Claude Opus 4.5 and Claude Haiku 4.5 in blind trials; Opus 4.5 generated on average $2.68 more per sale while buying agents using Opus paid $2.45 less per deal.
- Anthropic notes legal and consent uncertainties remain for AI agents transacting on users' behalf.

Anthropic Project Deal: AI Agents Trade on Marketplace
Anthropic’s internal Project Deal (69 employees, $100 per agent) showed Claude-powered agents autonomously negotiated and closed 186 real-world deals worth just over $4,000, and stronger model variants (Opus vs Haiku) produced systematically better outcomes. The newsletter also reports OpenClaw’s new ClawSweeper skill turned its repository into a self‑evolving maintenance system that processed roughly 5,000 issues in days. Separately, China is reportedly moving to block top AI startups from taking U.S. funding without government approval, narrowing exit/capital paths. Elon Musk-linked activity (xAI exploring a tie-up with Cursor and Mistral; SpaceX has an option-style structure tied to Cursor) aims to rapidly expand AI coding capability. The piece frames these signals as part of a broader shift from AI tools to agentic systems that govern developer workflows and new market interactions.
Anthropic's Project Deal Validates Agent Commerce
Anthropic ran "Project Deal," a one-week internal marketplace in December 2025 where Claude agents autonomously conducted transactions for 69 employees, producing 186 deals and more than $4,000 in total value across 500+ listed items. The experiment showed agent-to-agent commerce is viable but revealed model-driven inequality: participants using Claude Opus 4.5 gained measurable advantage over Claude Haiku 4.5 (Opus sellers extracted $2.68 more per item on average; Opus buyers paid $2.45 less; Opus agents closed roughly two more deals). The DEV Community post argues this success exposes a missing verification layer for agents on the open web and introduces GenGEO — an open-source, machine-readable merchant verification registry (HTTP API and MCP server) — to provide deterministic verified/unverified signals that agents can query before transacting.
Anthropic Pilots Agent-on-Agent Commerce Marketplace
Anthropic ran Project Deal in December 2025, an internal pilot that gave 69 employees autonomous AI agents to buy, sell and negotiate on a Slack-based marketplace. Agents completed 186 deals, exchanging over $4,000 in real goods. The experiment found a measurable quality gap between models: agents running on Claude Opus 4.5 consistently negotiated better deals than those on Claude Haiku 4.5, often without human participants noticing the difference. The trial demonstrated that autonomous agent negotiation works but highlighted an infrastructure bottleneck: human-first messaging platforms like Slack lack agent-native features needed to scale cross-vendor, cross‑organization agent commerce. The article also describes rosud-call, an SDK (npm) that provides agent-native messaging primitives and verified agent metadata to enable discovery, structured messaging, and autonomous confirmations across agent networks.
