Distribution Markets
Markets that trade on full probability distributions rather than single binary yes/no outcomes. Traders express a shape of belief (mean, variance, skew, multi-modal structure) and are paid by how close the realized outcome falls to the shape they staked on. Paradigm's Dave White paper (Dec 2024) formalized the modern version; Dekant is the first onchain production implementation.
Key insights
- Binary yes/no PMs are incomplete: they flatten nuanced beliefs into coin flips and pay the same whether you were barely right or sharply right. Distribution-native markets reward precision · pay more for being closer to the actual outcome. 130x volume growth from early 2024 to late 2025 = category's credibility moment (Tide manifesto, "Make Precision Pay").
- "What if we're capturing the wrong signal?" · binary markets flatten complex beliefs, losing precision that separates superforecasters from average predictors. 2024 French trader whale ($30M moving election odds) and Vanderbilt study (PredictIt 93% vs 67% on high-volume platforms) · more liquidity ≠ better signal (Jo).
- Information Vectors thesis: binary event contracts fragment liquidity and flatten beliefs into 1-bit structures. Achieving 8-bit resolution requires 256 separate markets. Proposes treating beliefs as vectors over probability distributions on a shared liquidity surface. Traders express full distributions; rewarded for variance compression (reducing entropy), not just final outcome correctness (functionSPACE).

Where it matters
This is the entire premise of Dekant. The three articles all converge on the same diagnosis (binary contracts under-resolve belief, fragment liquidity, and underpay precision) and propose essentially the same solution architecture (distribution-native / vector-of-beliefs / continuous-outcome markets). The volume growth cited (130x) plus the academic underconfidence-in-political-markets finding (prices compressing to 50%) form the empirical case that this category has tailwinds. For builders, the open implementation questions are: (1) what's the AMM invariant that supports a distribution surface? (L2-norm CFAMM, partition-of-unity smooth kernels), (2) what's the UX so retail can express a curve without a math degree? (sliders, drag-curve, presets), (3) how do you settle when realized outcome is continuous? (binned payouts, kernel-weighted partition-of-unity).
Connections
- Information aggregation · distribution markets aggregate at higher dimension
- Price discovery · argued to be higher-bandwidth in continuous space
- Forecasting accuracy / Calibration · the metric distribution markets claim to improve
- Wisdom of crowds · distribution markets aggregate richer crowd signals
- Liquidity provision · single shared liquidity surface across the whole distribution
- Superforecasting · distribution markets reward the precision skill that separates superforecasters from amateurs
- LMSR / market scoring rules · the mechanism family naturally extended to multi-outcome
