The Oracle · free · Kalshi × Polymarket × Polymarket US
One event. Many prices.
Find price differences across US and international prediction markets. Start with what the questions mean, then compare costs, available size and timing across Kalshi, Polymarket and Polymarket US.
Every pick below changes to this amount. A contract pays $1 if its answer comes true and $0 if not.
Buy both answers. Compare the combined payout with the cost. The modeled payout depends on both orders filling and the stated result rules. Most money per day first, at your amount.
Already want to bet on something? Here’s where it costs less. The saving is real at the prices shown. The bet is still a bet.
Cheaper here than the price on the bigger app. Still a bet: you can lose it all. We’re testing these on paper first.

Money back early.
Tap I did this on a card and we’ll keep an eye on it. If you can sell both sides early for a profit, you’ll see it here first.
Semantic market intelligence
Read the event. Find the difference.
Jianco helps human traders and market makers find pricing differences within and across markets, not just match one YES with one NO. Different wording can describe the same result, opposite results or partly related questions. The result rules—not the wording alone—determine what a combination can pay.
News changes prices at different speeds. An announcement, result or deadline can create a discount moment before another market responds. Jianco’s purpose is to connect those moments with the meaning and cost of the outcomes.
Available today: AI-assisted candidate matching, deterministic rule verification and live price-feed checks. The public page shows cross-app pairs, Cheapest app comparisons and clearly labeled practice-only bargains. Planned: an expanded public semantic map of related questions, combinations with more than two positions and unequal amounts, measured live catalyst response and supported developer data access.
Before acting: check fresh prices on both apps, fees, available size, fills and result rules. A modeled payout depends on compatible rules and all orders filling; a prediction can lose. Different wording does not ensure different prices or profit. Each app’s access rules still apply.
Observed gaps and practice results are not realized returns. See the Track record for finished picks and their assumptions.
Track record
$1,000 following the Oracle.
Practice money. Every pays-either-way pick gets up to $100, or less if less was for sale. The money comes back when the event ends.
Results reflect the prices and size available on each check, not a limit on future opportunities. Practice money at the prices we saw; real orders can fill worse.
Two words you’ll see
Contract · pair
A contract pays $1 if its answer comes true and $0 if not. It costs less than $1, and the price is roughly the crowd’s guess of the chance.
A pair is one “yes” on one app plus one “no” on the other. If the answers are exact opposites under compatible rules and both orders fill, one pays $1. Read each card’s exceptions and result rules.
Contracts or shares are the two apps’ words for the same thing: one $1 ticket.
