Odds comparator FAQ

Are these live sportsbook or Kalshi odds?
No. You type educational scratch values. Live Polymarket Yes/No prices live on /markets. Kalshi and Novig stay Not listed until written BD / data license — ChanceWire never invents those quotes.
Can I share a link with my odds?
Yes. The tool updates the URL softly with ?p= (probability as 0–1 fraction), ?american=, or ?decimal= so you can share a literacy example. Shared links are educational — not live market data.
How does this relate to prediction-market prices?
Polymarket outcome prices are already close to implied probabilities (before fees and spread). Use the implied probability calculator for 0–1 / ¢ inputs, or break-even for required win-rate framing.
Does this invent EPC, CPA, or “best odds” rankings?
No. SoftCta educational converter math only. No invented rates, EPC, CPA, or best-platform claims. SoftCta /r locks stay unchanged.
Is this financial advice?
No. Educational SoftCta only. Not legal, tax, or financial advice.
