Why journalists use this
Prediction markets are useful in reporting when they're framed honestly. That means understanding both the price and the market structure behind it.
Not every quote is worth citing
A 62% price means very different things in a deep market versus a sleepy one. We surface the context so you can tell the difference.
Divergence is often the story
When platforms disagree, that spread is worth investigating — different traders, different liquidity, or different contract wording.
Deadline-friendly
Find the right market, get a defensible price, and understand the cross-platform picture — in minutes, not hours.
Multi-platform by default
A newsroom that only checks one venue is going to miss pricing disagreements, structural quirks, and what the broader market actually believes.
How PredictionMarkets.US is different
This isn't a trading terminal. It's reporting infrastructure.
Cross-platform by default
PredictionMarkets.US
Shows Kalshi, Polymarket, and PredictIt side by side — with more platforms coming soon.
Typical single-platform workflow
Most journalism tools start from a single platform view and treat that quote as the market.
Divergence as signal
PredictionMarkets.US
When prices separate, we treat that spread as something worth investigating and explaining — not smoothing over.
Typical single-platform workflow
Most tools hide disagreements instead of showing where consensus breaks down.
Built for citation discipline
PredictionMarkets.US
Every workflow is designed around defendable reporting: what the question was, where the price came from, and why it moved.
Typical single-platform workflow
Most market pages are built for trading, not for publication-grade sourcing.
FAQ
Before you cite a price
Three checks before quoting a prediction market:
- Liquid enough? A thin book can show wild numbers. Check depth.
- Do platforms agree? If Kalshi says 62% and Polymarket says 71%, that spread matters.
- Does the wording match your claim? "By June 30" and "by end of year" are not the same market.
Miss any of those and you're citing a market more confidently than it deserves.
