For journalists and researchers

Email [email protected] with “Press” in the subject line. Tell us your deadline and we will prioritize it. We can explain a specific comparison, confirm a figure, or provide data for a story.

Suggested attribution:

Source: ThePredictionMarkets.com, prices from Kalshi and Polymarket, as of [date and time, with time zone].

• Link to the market or comparison page you used, so readers can see the current price.
• Give a timestamp. Prediction-market prices move constantly, and every TPM price shows its age.
• Describe a price as the market’s implied probability (for example, “traders put the chance at 62%”), not a forecast by TPM.
• Call a difference between venues a “price gap”. Only gaps TPM marks as actionable are tradable, and even those exclude fees.
• Name the venues. TPM compares their prices; it does not run a market of its own.

Our methodology explains how we decide two markets ask the same question, check that they settle the same way, calculate price gaps and label freshness. Live feed health is on the status page.

TPM Inc. is an independent company with no affiliate or revenue-sharing deals with any venue. More on the about page.
