I mercati informativi are systems that convert dispersed knowledge into a price signal. Participants buy or sell contracts based on what they believe will happen, and the price tends to reflect the crowd’s best estimate of the outcome. In cyber security, this idea is useful because it can turn many weak signals into a single forecast: the likelihood of a breach, the success of a phishing campaign, or the probability that a vulnerability will be exploited.
For defenders, information markets can support risk prioritization, incident planning, and threat intelligence review. For attackers, the same mechanism can be abused by seeding false claims, manipulating sentiment, or exploiting bad event definitions to distort the signal. The security value depends on clean rules, reliable settlement, and resistance to manipulation. If the underlying data or incentives are weak, the “price” stops being a good estimate and becomes just another surface for influence operations.
