PolyGround vs Kalshi
Kalshi is a regulated exchange for trading event outcomes with real dollars. PolyGround is a free game that borrows the format and removes the money.
Kalshi is a US event exchange operating under financial regulation, where participants trade contracts on real-world outcomes in dollars. No crypto is involved — it is a conventional regulated venue, which is precisely its appeal to people who want the format without the crypto layer.
PolyGround shares the format and nothing else. Questions resolve yes or no, probabilities move live, and you take a side — but the coins are virtual, hold no monetary value, and can never be purchased or cashed out. It is a game with a leaderboard, not a venue.

The difference in one line
Kalshi is a place to act on your forecasts. PolyGround is a place to find out whether your forecasts are any good.
The friction gap
A regulated exchange has to verify who you are and where your money comes from. That is a feature, not a flaw — it is what makes it a legitimate financial venue rather than something operating in a grey zone. But it means signing up is a process, and there is a real gap between “I am curious about prediction markets” and “I have completed identity verification and funded an account.”
PolyGround exists in that gap. Install, tap through onboarding, start with 1,500 coins on the house. If you decide the format is not for you, you have lost a few minutes.
What the game adds
Because nothing is at stake, PolyGround can do things an exchange never would. Holding YES or NO longer raises your stake and releasing locks it in, which turns a trade into a physical action. Swipe to cash out lets you take a profit before a question resolves. XP accumulates permanently on correct calls, so your record survives a bad run in a way a balance does not. There are badges, quests, daily streaks, rank tiers, and leaderboards ranked by coins, XP or win rate.
None of that belongs on a regulated exchange, and all of it is the point of a game.
Which should you use?
Kalshi, if you want regulated exposure to event outcomes in dollars, with no crypto, and you are prepared to verify and fund an account.
PolyGround, if you want to learn to read these markets, settle arguments with friends, or just enjoy being right — without money, verification, or any way to lose something you care about.
