What if marketplaces rewarded the best product instead of the best marketing? OpenMarket (in research preview), is a multi-agent marketplace where sellers pitch, competitors challenge their claims, and independent truth agents verify the evidence as they compete to earn a buyer's sale. Here, claims don’t count just because they’re written on a product page. They have to survive scrutiny and be proven.

Could you build this?
Partial The marketplace UI and basic LLM prompts are simple, but creating an automated multi-agent adversarial verification framework that reliably validates real-world claims requires advanced consensus and verification architecture.
What it would actually take: Requires an orchestration layer (e.g., LangGraph, AutoGen) simulating multi-agent debates, coupled with automated web scraping and proof verification pipelines. The difficult part is engineering reliable epistemic evaluation logic, anti-collusion protocols between LLM agents, and verifiable external grounding mechanisms to prevent sybil attacks and hallucinated consensus.
