Cross-venue edges,
before the crowd.
Five prediction-market venues price the same events differently every minute. PROVISUM catches the gaps — cross-platform hedges where YES + NO < $1.00 can point to a return when both venues resolve on identical terms.
Prediction markets don't agree with each other.
The same question — "Will X happen?" — trades on Polymarket, Kalshi, PredictIt, Smarkets and Limitless at the same time, at different prices. Most of the time the gap is noise. Sometimes it's an arbitrage: a combination that pays out whichever way the world goes.
Those windows are small and they close fast. Finding them by hand means watching dozens of order books across five sites at once. Nobody can.
A machine that never blinks.
Crawl everything
Live order books from all five venues, refreshed on a schedule — thousands of markets, continuously.
Match the same event
IDF-weighted matching with strike, date, scope and parent-question guards aims for the same underlying outcome — not just similar words. Always verify the resolution rules yourself.
Price the hedge
Both directions, with each venue's real fee model, so the spread you see is the spread you'd actually capture.
Verify the depth
One click walks the real order books for your size — because a 9% edge on five contracts isn't a 9% edge.
Edges on the board this minute
These are real, open opportunities. The size of each edge and the venues involved are live — which market, and the exact legs to trade, are one click behind the paywall.
The engine doesn't sleep
Opportunities are discovered, tracked and closed around the clock. Here's the recent window at a glance — the specifics live inside the terminal.

From raw books to a modeled edge
- 01
Ingest
Poll Polymarket (Gamma + CLOB), Kalshi (trade-api), PredictIt, Smarkets and Limitless. Drop dead books and parlay noise.
- 02
Match
Rare tokens (candidate names, strikes) carry the signal; parent-question and date guards kill look-alikes.
- 03
Compute
Both arb directions, fee-adjusted per venue. Suspects — too-good-to-be-true edges on weak matches — are excluded.
- 04
Verify
Walk the live book for your contract count. If the edge doesn't survive depth, you see that before you act.

A statistics platform — not financial advice
PROVISUM is an informational and educational data & analytics tool. It collects publicly available prices from third-party prediction-market venues and computes statistics (spreads, ROI, historical detections). It is not financial, investment or trading advice, not a broker or exchange, and does not execute trades or hold funds.
- Every number shown is a statistic derived from collected data, not a recommendation to buy or sell anything.
- Prices are snapshots pulled on an interval and can be delayed, incomplete or wrong by the time you see them — always confirm live on the venue.
- A displayed edge only holds if both markets resolve on identical rules, sources and deadlines; verify that yourself before acting.
- Fees, taxes (winnings are taxable and a hedge's two legs may sit in different tax buckets), order-book depth, slippage, eligibility (venues are jurisdiction-restricted) and price movement can all erase an edge. Nothing here is guaranteed.
- Trading prediction markets carries risk of loss. Never trade money you can't afford to lose. Do your own due diligence.
