Prediction Market Bankroll Calculator: How Much Do You Need?

How much money do you actually need to start trading prediction markets? The answer depends on your strategy, risk tolerance, and time horizon.

Minimum Starting Capital

You can start on Polymarket with as little as $50 in USDC. On Kalshi, the minimum per contract is $1. But minimum and optimal are very different things.

Bankroll by Strategy Type

• Casual/learning: $50-200. Enough to place a few bets and learn the mechanics.
• Active trading: $500-2,000. Allows proper position sizing across 5-10 markets.
• Serious trading: $2,000-10,000. Full Kelly sizing, diversification, and copy trading.
• Professional: $10,000+. Maximize edge across all available markets.

The 2% Rule

Never risk more than 2% of your bankroll on a single trade. With $1,000, that's $20 max per position. This keeps you in the game through inevitable losing streaks.

How Copy Trading Changes the Math

With Polifly's copy trading, you can follow proven wallets automatically. This means your bankroll works harder because you're diversified across a professional's positions instead of making individual bets.

Growing Your Bankroll

Start small, track your results, and scale up as you prove consistent profitability. Most successful traders on Polymarket started with under $500 and grew from there.
