Is there a free version of Kalshi?
An accurate comparison between the real-money prediction markets and Ledger, written by the free one. No knocks, no fine-print tricks. Just what each product is.
Updated July 22, 2026
Kalshi has no free tier: it is a federally regulated exchange where every contract is real money, and the closest thing to free is a developer sandbox with mock funds, meant for testing, not play. If you want the prediction-market experience without dollars, Ledger is a free-to-play alternative. You make the same kind of calls on real events, they settle against real results, and you build a permanent public record, with a virtual currency instead of cash. 18+.
What is Kalshi, exactly?
Kalshi is a prediction-market exchange regulated by the Commodity Futures Trading Commission as a designated contract market. You trade event contracts: yes-or-no questions about real outcomes, from elections to economic data to sports. A contract settles at one dollar if the outcome happens and zero if it does not, and the price in between reflects what the market currently thinks the odds are.
It is real money end to end. You deposit dollars, you pay a transaction fee on most trades, and you can withdraw what you win. You have to be 18 or older to open an account. It is a serious, regulated financial product, and we describe it that way on purpose. Nothing on this page is a knock on Kalshi. It does what it says.
Is there a free version of Kalshi?
No. Kalshi is a real-money exchange, and every contract on it is bought with dollars. It maintains a separate demo environment with mock funds, mainly used for testing its trading systems, but that is a sandbox, not a free tier of the product. If you want to make the same kind of calls without money, that is what a free-to-play prediction game is for.
The distinction is worth keeping sharp. A sandbox exists so systems can be tested. A free game exists so the calls themselves can be the point.
What is Polymarket?
Polymarket is the other name people reach for. It is a crypto-based prediction market: positions are funded and settled in USDC, a dollar-pegged cryptocurrency, on a blockchain. Prices work the same way as on Kalshi, with a share of an outcome trading between a cent and a dollar. For years it was closed to United States traders; as of 2026 it offers US access through a regulated exchange it acquired, with identity checks. It is also real money end to end. There is no play-money version of Polymarket either.
How is Ledger different?
The honest answer starts with a disclaimer: Ledger is not a prediction market. There is no trading, no order book, no deposits, and no cash-out. Ledger is an entertainment product and a public record of judgment. You spend Float, a virtual currency that refills daily, to make calls on real events. Correct calls earn Standing, a permanent score that never goes down. Nothing of monetary value ever enters or leaves.
What the three products share is settlement against reality. Where they part ways is everything that touches money.
| Kalshi | Polymarket | Ledger | |
|---|---|---|---|
| Real money | Yes. US dollars in an exchange account. | Yes. Positions settle in USDC, a dollar-pegged cryptocurrency. | No. Float is virtual and has no cash value. |
| What you risk | The dollars in each contract. | The crypto in each position. | Float, which refills every day. |
| What you keep | Winnings, minus fees. | Winnings, in USDC. | Standing, a permanent record of correct calls, plus an optional public record page. |
| Settlement | Contracts settle to one dollar or zero against defined outcome rules. | Markets resolve against real-world outcomes. | Real finals and boxscores for sports, real prices for crypto, a source-gated public-record check for culture and world calls. |
| Age | 18+ | 18+ | 18+ |
| Cost | Transaction fees on most trades. | No trading fees on most markets; moving crypto in and out has its own costs. | Free. There is nothing to buy. |
Can you practice prediction markets without money?
Yes, in two ways. Third-party simulators mirror live market odds with a play balance, and free-to-play prediction games like Ledger grade your calls on real events against real results. Neither costs anything, and neither can teach you what risking real dollars feels like. There is no practice mode for that part.
What a free game can teach you is your own calibration. Ledger's optional public record grades every call against the real result, not self-scored, and it only speaks a hit rate for a confidence band once you have five settled calls in it. Small samples stay silent. That is a more honest mirror than most bettors ever get.
What does Ledger have that a real-money exchange never will?
Mechanics that only work when nothing is for sale. The Shadow Line shows what a sportsbook would have taken from you by now, in real dollars that nothing actually took. The Dividend grants free Float every week, and more when players collectively rest. Rest itself is a stat on your record. A venue that earns fees on volume cannot build any of that.
The Shadow Line is computed from your actual graded calls, recomputed server-side, and it deliberately understates. It is not a savings account and not an audit. It is the running answer to one question: if these had been real bets at a real book, what would the book have taken by now?
The Dividend is free Float with no strings. Every week, 750 falls for every player, and another 250 falls for every 25 rest days players take collectively. It is never triggered by losses, and there is no countdown attached to it anywhere. Each rest day is written server-side, one per account per day, so the stat is real.
At a casino, the payout comes when the house wins. Here, it comes when you keep your money, and when you rest. An exchange cannot copy that, not because its people are worse, but because its revenue is volume.
What do you actually keep on a free prediction game?
On Kalshi, you keep your winnings. On Ledger, you keep a record. Standing never goes down, and if you opt in, your record lives at a public page anyone can check: every figure recomputed from your stored, graded calls, pushes counted but excluded from your hit rate. You also keep whatever the record teaches you about your own judgment, which is the part of this hobby that was never for sale.
Which should you use?
If you want to put real money on event outcomes, use Kalshi or another regulated venue. Ledger is not that and does not try to be: nothing goes in, nothing comes out, and a virtual currency is not a portfolio. If what you want is the call itself, the read before the game, the settle against the real final, the record that builds, without the losses, that is exactly what Ledger is. They are different products, and only one of them costs money.
