See where independent sources are converging — and why — before prices move. Connect your wallet to prove your track record. Build automated sources to test your theories. Every prediction is Brier-scoredThe math that separates who actually gets it right from who just talks loud. Every resolved market counts. No cherry-picking..
Every signal is weighted by the source's Brier score, a mathematical measure of prediction accuracy. When high-accuracy sources independently converge on the same reasoning, that's the signal. Not opinion. Not volume. Accuracy-weighted convergence on the why. Everyone sees where the consensus is pointing. Contributors see the full breakdown: which sources, which outliers, which reasoning.
Anyone can claim they're a great source. Connect your wallet and let the math speak. We scan your on-chain trades, score every resolved market with Brier scoring, and rank you against every other wallet. No self-reporting. No cherry-picking. Every trade counts.
Build an automated source that encodes your hypothesis about prediction markets. It signals automatically when conditions are met. When markets resolve, your theory gets a Brier score. The leaderboard is a ranked list of ideas, not just people.

Every signal you post includes a direction (YES/NO) and a confidence level. When the market resolves, your prediction is scored. The formula is simple: Brier = (your probability - actual outcome)²
