PROVISUM

Four prediction-market venues price the same events differently, and the gaps move by the minute. PROVISUM scans Polymarket, Kalshi, PredictIt and Limitless every ten minutes and surfaces cross-platform hedges where buying YES on one venue and NO on another costs under $1.00 — a position that can return when both venues resolve on identical terms.

Each edge on the board shows both legs, the venues, the combined cost and the margin, so the arithmetic is visible rather than asserted. Matching happens only on identical resolution terms, which is the part that decides whether an apparent edge is real or two questions that merely read alike.

Signing up is free and shows the marginal edges; Pro ($79/month) unlocks every signal. Prediction markets carry real risk and nothing here is financial advice.
