Credibility Markets
Markets where participants stake on the accuracy of claims or sources, building continuously updated trust scores rather than static reputations. Treats trustworthiness as a tradeable probability over time. A subset of the broader "probability infrastructure" thesis.
Key insights
- Single-source concept article. Probability layers thesis (Aggie): PMs are a proof-of-concept for a broader shift · probability as infrastructure. Three layers beyond trading: 1. Attention markets · price content virality forward 2. Credibility markets · turn trust into a continuously updated score 3. Demand markets · capture consumer intent before production
- Credibility markets specifically treat trustworthiness as a probability over time. Instead of static "verified" badges or one-shot reputation systems, every claim or source has a running probability score that traders update by staking. A news outlet, a researcher, an AI-generated artifact · each gets a continuously-priced credibility curve.
- Endgame framing: probability signals embedded invisibly into every decision surface on the internet. Credibility markets are the layer most likely to be adopted by social platforms, news aggregators, and AI safety pipelines because trust is the single most-needed primitive in an AI-saturated information environment.

Where it matters
Credibility markets are speculative · there's only one article cataloged at onprediction · but the mechanism design is the most natural next step after the PM-as-info-finance thesis. If PMs can price the probability of an event resolving YES/NO, they can price the probability that a claim will resolve as true after future verification. Two practical applications: (1) AI-generated content authentication (every claim has a market-priced trust score), (2) news source rating (a continuously-priced replacement for static media-bias rankings). For PM platforms, this is a structural expansion of TAM beyond event-betting into the much larger category of "things people want a probability on." For Dekant, the curve-drawing primitive is more suited to credibility than binary · credibility isn't really YES/NO, it's a distribution over "how likely is this claim true given different verifiers."
