# Prediction market skin-in-the-game mechanism creates dual-use information aggregation and gambling addiction because the incentive structure is agnostic about user epistemic purpose

Fortune's investigation documents a 12x volume increase in prediction markets (from ~$500M weekly mid-2025 to ~$6B by January 2026) coinciding with mental health clinicians reporting increased addiction cases among men aged 18-30. Dr. Robert Hunter's International Problem Gambling Center attributes this to prediction market accessibility. The mechanism is dual-use: skin-in-the-game incentives that create information aggregation advantages for epistemic users simultaneously create gambling addiction dynamics for entertainment users. The key insight is that prediction markets are perceived as "more socially acceptable" than sports betting due to branding around research/analysis, creating a lower stigma barrier that accelerates adoption. This removes a natural demand-side check on gambling behavior. Kalshi's launch of IC360 prediction market self-exclusion initiative signals industry acknowledgment that the addiction pattern is real and widespread. The convergence of multiple major outlets (Fortune, Quartz, Futurism, Derek Thompson) on this narrative in the same week suggests this is becoming a mainstream counter-narrative to prediction market epistemic benefits. The KB's existing claims about information aggregation through incentives do not account for this harm externality because they assume a single user population when there are at least two: epistemic users who aggregate information and gambling users who engage in addictive behavior. The mechanism is the same; the outcome depends on user purpose.
