Best Free Prediction
Markets in 2026
Several prediction markets are completely free to use: no deposit, no purchase required. Here's how they work, what "free" actually means on each platform, and which is right for you.
Best free prediction market overall

What does "free" mean in prediction markets?
Not all free prediction markets are free in the same way. There are three distinct models, and knowing which one you're on changes everything about how the platform works.
Pure play money
Platforms like Metaculus use points that have no monetary value at all. There is nothing to deposit, nothing to cash out, and no real money anywhere in the system. You forecast purely for calibration, reputation, and intellectual engagement. This is the cleanest "free" model: no regulatory complexity, no sweepstakes rules, no state restrictions.
Free play money + optional real-money cashout
Platforms like Manifold and Verse operate under a sweepstakes model. You receive free virtual currency (mana or coins), trade markets, and can optionally convert accumulated currency to real money under sweepstakes rules: subject to state restrictions, play-through requirements, and fees. Playing is free; the real-money layer is optional.
Very low cost (not technically free)
Platforms like the Iowa Electronic Markets require a small real-money deposit (up to $500 account cap) but charge no trading fees: only the bid-ask spread. This is not free to join, but it's the cheapest way to trade real-money prediction markets. Useful context for setting expectations around what "almost free" looks like in real-money markets.
Manifold Markets — Best free platform overall
Free mana, optional real-money cashout
Founded in 2021, Manifold runs a community-driven prediction market with over one million markets on politics, science, sports, pop culture, personal goals, and virtually anything else users want to create. Every account starts with M$500 mana, and free daily bonuses keep active users supplied. Markets are created by users and can cover any question, from presidential elections to software release dates.
The sweepcash system is what separates Manifold from purely play-money platforms. Mana profits can be converted at M$100 = $1, subject to a 1× play-through requirement and 5% cashout fee. In practice, skilled forecasters have earned hundreds of real dollars starting from nothing. The catch: mana itself has zero monetary value, so you're not "investing": you're forecasting.
What costs money (if anything)
- Trading: Free: mana only, no deposit ever required
- Market creation: Free
- Sweepcash cashout: 5% fee on withdrawal
- Optional mana purchases: Users can buy extra mana ($10+) but never have to
- State restrictions: Sweepcash unavailable in DE, ID, MI, WA
Users who want to forecast across a wide range of topics for free, with the option to eventually earn small amounts of real money through performance.
Metaculus — Best for serious free forecasting
Serious forecasting, zero money required
Founded in 2015, Metaculus is the gold standard for serious quantitative forecasting outside financial markets. It hosts over 20,000 curated questions on science, geopolitics, technology, economics, and global catastrophic risk: questions like "Will GPT-5 exceed human expert performance on MMLU by 2026?" or "What is the probability of a nuclear detonation by state actors before 2030?"
Unlike Manifold's user-created markets, Metaculus questions are editorially curated for resolution clarity and analytical value. The platform tracks forecaster calibration using a Brier score: rewarding accurate probability estimates, not just binary right/wrong calls. Top forecasters build public track records that are visible to researchers, journalists, and policymakers who cite Metaculus data. Participation is entirely free, always.
What you get, what it costs
- Cost: Completely free: no account deposit, no purchase
- Points: No monetary value, purely for calibration tracking
- Questions: 20,000+ curated, plus community forecasting tournaments
- Numerical predictions: Forecasts on continuous distributions, not just binary yes/no
- Forecaster profiles: Publicly visible calibration scores and track records
- Metaculus Journal: Research publication with community forecasts
Analysts, researchers, students, and anyone who wants to develop rigorous forecasting skills without any financial exposure. No state restrictions, no sweepstakes rules.
Verse — Best free casual platform
Free daily coins, parlay-style picks
Verse (versegaming.com) is a sweepstakes-style prediction platform focused on sports and pop culture. Every day, active users receive free virtual coins to spend on parlay-style picks: predict outcomes across multiple events, and correct picks multiply your coin balance. Like Manifold, coins can optionally be converted to real cash under sweepstakes rules.
Verse skews toward casual engagement: the interface emphasizes streaks, daily challenges, and social sharing rather than detailed orderbooks or probability calibration. If you want to predict NFL game outcomes or award show winners without putting any money at risk, Verse is the most approachable option in this list. It does not require financial sophistication or forecasting background to enjoy.
What you get, what it costs
- Cost to play: Free: daily coin allocation with no deposit
- Market types: Sports, pop culture, current events
- Format: Parlay-style multi-event picks
- Real-money path: Sweepstakes model: coins convert to cash under applicable rules
- State restrictions: Applies; check at sign-up
Sports fans and casual predictors who want to make picks on games and entertainment events for free, with an optional real-money upside through a sweepstakes model.
Iowa Electronic Markets — Very low cost, not technically free
The original academic market
Founded in 1988 at the University of Iowa, the Iowa Electronic Markets is one of the oldest continuously operating prediction markets in the world. It is not free: you deposit real money (up to the $500 account cap). But IEM charges no trading commissions, only the natural bid-ask spread, making it the cheapest real-money political prediction market available to US users.
IEM is primarily used for US political markets (presidential, congressional races) and has a strong academic research history. Its forecasts have been studied in peer-reviewed economics literature. The low cost and academic context make it worth knowing about even though it's not technically free.
- Founded: 1988, University of Iowa
- Account max: $500 real money
- Trading fees: None: bid-ask spread only
- Markets: Primarily US politics
- Access: US residents; academic context
Can you make real money for free?
Yes — with Manifold's sweepcash and Verse's sweepstakes model
Both Manifold and Verse operate under US sweepstakes law, which allows platforms to offer prize redemptions without being classified as gambling: provided they also offer a free entry method. This is the same legal framework used by sweepstakes casinos like Chumba and Stake.us.
Mana profits convert to sweepcash at M$100 = $1. A 1× play-through must be completed before withdrawal, and a 5% cashout fee applies. Minimum cashout varies. Skilled forecasters, especially on major political or scientific markets: have accumulated meaningful sweepcash balances over time. Not guaranteed income, but real potential with zero upfront cost.
Verse's daily free coins generate sweepstakes entries that can be redeemed for real prizes. The mechanics are simpler than Manifold's: it's more like a daily-challenge prize pool than a financial market. Returns are modest and depend on pick accuracy, but the entry cost is always zero.
Important: Sweepstakes earnings are not investment income. Manifold's mana has no monetary value; only sweepcash does. State restrictions apply to both platforms. Never treat free prediction markets as a substitute for savings or investments.

| Verse | Free daily coins | Sweepstakes redemption | Casual sports picks | Varies by state |

Common questions about free prediction markets
Is there a completely free prediction market? +
Yes. Manifold Markets gives every new user M$500 in free mana at signup: no deposit, no credit card, no purchase required. You can trade thousands of markets indefinitely on mana alone. Metaculus is also completely free: it uses a points system with no monetary value whatsoever, and you never need to pay anything to participate.
Can I win real money without depositing on Manifold? +
In most US states, yes, but with caveats. Manifold's sweepcash system lets you convert mana profits to real USD at M$100 = $1. You must meet a 1× play-through requirement and pay a 5% cashout fee. Sweepcash is unavailable in Delaware, Idaho, Michigan, and Washington. Mana itself has no monetary value; only sweepcash does.
What is Metaculus Points? +
Metaculus Points are a scoring currency with no monetary value. They are awarded based on calibration: how accurately your probability estimates match outcomes, measured by the Brier score. Points build your public forecasting track record, which is visible to researchers and journalists. You cannot withdraw, sell, or convert them. Their value is purely reputational.
Are free prediction markets accurate? +
Research suggests yes, often surprisingly so. Metaculus has a strong track record: its community forecasts beat baseline rates on geopolitical and scientific questions, and Brier scores compare favorably to professional analyst surveys. Manifold's play-money markets also show meaningful accuracy on current events and elections, though liquidity is shallower on niche topics.
What's the catch with Manifold's free mana? +
Several. First, mana has no monetary value: only sweepcash does. Second, you must meet a 1× play-through before cashing out sweepcash. Third, there's a 5% cashout fee. Fourth, sweepcash is unavailable in DE, ID, MI, and WA. Fifth, markets can resolve N/A, returning stakes but yielding no profit. The free M$500 signup mana is mana only: sweepcash is earned through trading performance.
