How to Trade
on Manifold
Manifold is a free prediction market with no real money, no KYC, and no risk. It's the best place to learn prediction market mechanics, build a calibration track record, and practice position sizing before trading with real money on Kalshi. This guide explains everything: Mana, sweepstakes cash, market creation, and how to graduate to real-money trading.
What makes Manifold different
No risk, no KYC, no crypto
Manifold requires no SSN, government ID, bank account, or credit card. Sign up with your Google account and start trading immediately. The play-money currency (Mana) has no USD value. This is the reason Manifold is recommended as the starting point for every prediction market beginner.
Optional real USD rewards
Manifold's sweepstakes feature uses a separate currency called Sweepcash. You can earn Sweepcash through trades and redeem it for real USD prizes. Amounts are modest, but the sweepstakes layer lets you experience real incentives without financial risk. Available in most US states under sweepstakes law.
200,000+ user-created markets
Manifold has more markets than any other prediction platform: on politics, sports, science, tech, pop culture, and completely niche personal bets. The breadth makes it ideal for practicing across different market types and building calibration.
Measurable forecasting skill
Manifold tracks your calibration score: predicted probability vs actual outcome rate. This is the primary metric for forecasting skill. A strong Manifold calibration record is the best credential you can build before putting real money on the line.
How to start trading on Manifold
- 1 Create a Manifold account — no ID requiredGo to manifold.markets and sign up with your Google account or email. No SSN, no government ID, no KYC verification: this is a free platform. Creating an account takes under 2 minutes. You'll receive M$1,000 in Mana (play-money currency) immediately to start trading. Manifold is available to users in all countries, including all US states, with no restrictions.
- 2 Understand Mana — the play-money currencyManifold uses "Mana" (M$) as its currency. M$ have no cash value: you cannot withdraw Mana as USD. They exist purely for prediction market practice and platform reputation building. You receive M$1,000 on signup, and earn more through referring friends, participating in special events, and trading well. Think of Mana as your prediction market training currency.
- 3 Explore the market catalogManifold has hundreds of thousands of user-created markets on virtually any topic: politics, sports, science, technology, culture, personal bets, and highly niche questions. The most popular markets have high liquidity. You can browse by category, trending markets, or use the search. The diversity of markets is Manifold's main advantage over any real-money platform.
- 4 Place your first tradeClick any market to see the YES/NO probability. Click "YES" or "NO" to bet. Enter how much Mana you want to risk. Manifold uses an automated market maker (AMM) model: you're trading against a liquidity pool, not individual counterparties. Your trade immediately moves the market probability in your direction. Limit orders are also available for more precise entry.
- 5 Create your own marketAnyone can create a market on Manifold: on any question you want, with any resolution criteria. Click "Create market" and define the question, resolution method, and close date. You can be the resolver (you decide the outcome) or designate a trusted resolver. Creating markets is how Manifold enables its massive variety: the platform is community-driven, not editorially curated like Kalshi.
- 6 Track your calibration scoreManifold tracks your forecasting calibration: how often your predicted probabilities match actual outcomes. If you consistently predict 70% and those things happen 70% of the time, you are well-calibrated. This score is visible on your profile and is the primary reputation metric on Manifold. Building a strong calibration record here is the clearest proof of forecasting skill before moving to real-money platforms.
- 7 Try Manifold Sweepstakes (real cash prizes)Manifold offers a separate sweepstakes layer called "Sweepstakes" where you can earn real USD prizes by trading a separate currency called "Sweepcash." Sweepstakes markets operate under US sweepstakes law (free alternative method of entry). You can earn real money rewards without risk: though prize amounts are modest compared to real-money prediction markets. Sweepcash earnings can be redeemed for USD.
- 8 Graduate to real-money platformsAfter trading on Manifold, you'll have a calibration record, market intuition, and experience sizing positions. When you're ready to trade with real money, use your Manifold track record as a baseline. Open a Kalshi account for real-money trading across sports, politics, and economics. The transition is smooth: the concepts are identical, just with USD instead of Mana.
The recommended learning path: Manifold → Kalshi
The biggest mistake new prediction market traders make is depositing real money before they understand how markets work. Here's the two-step path that works:
Why this matters: On Manifold, a bad run of trades costs you nothing except Mana. On Kalshi with $500, a 50% drawdown costs $250. The emotional and financial cost of learning on a real-money platform is high. The time spent on Manifold is not wasted: it's the most cost-effective prediction market education available.
Common questions about Manifold
Can I make real money on Manifold? +
Not through Mana: it has no cash value. However, Manifold's Sweepstakes feature (Sweepcash) allows you to earn real USD prizes. Sweepcash is a separate currency earned through trades and promotions, redeemable for real money. Prize amounts are modest compared to real-money platforms. Think of it as a free lottery ticket attached to a learning platform.
Is Manifold available in all US states? +
Yes. Since Manifold uses play-money (Mana) with no cash value, it's available in all 50 US states with no restrictions. The sweepstakes layer (Sweepcash) is available in most states under sweepstakes law: standard exclusions for places like Quebec may apply to the sweepstakes portion.
How does Manifold's AMM (automated market maker) differ from Kalshi? +
Manifold uses a constant-product AMM (similar to Uniswap in DeFi) where your trades move the probability based on pool size. Kalshi uses a traditional limit orderbook where humans post bids and offers at specific prices. On Manifold, you always get filled instantly at a price determined by the pool. On Kalshi, you may wait for counterparties to fill your limit order. Both models work; Kalshi's orderbook gives better price control for large trades.
Can I use my Manifold track record to trade professionally? +
There's no formal credential system, but a strong Manifold calibration score (>2,000 resolved markets, well-calibrated) is the best objective evidence of forecasting skill available publicly. Superforecasting organizations, hedge funds with macro trading desks, and some prediction market analysts do review Manifold track records. It's the closest thing to a public prediction market résumé.
