What is the three-tier bankroll staking system?

The three-tier system sizes each position as a percentage of total bankroll rather than a fixed amount. Cautious tier: 1-2% for new markets or low-conviction reads. Standard tier: 3-5% for well-researched positions. Max tier: 5% for your strongest read of the week. The 5% ceiling is never exceeded regardless of confidence.

Why should prediction market traders use fixed percentage staking instead of fixed amounts?

Fixed amounts expose traders to ruin during losing streaks because each loss represents a growing share of a shrinking bankroll. Fixed percentage staking scales stakes down automatically as the bankroll shrinks, extending survival during variance. A trader using 5% fixed percentage staking retains $599 after 10 consecutive losses from a $1,000 starting bankroll, compared to near-zero for a trader sizing emotionally.

What percentage of bankroll should I stake per prediction market position?

Most positions should be sized at 3-5% of current bankroll. Use 1-2% when entering unfamiliar markets or acting on instinct without deep research. The absolute ceiling is 5% - even for your highest-conviction trade of the week. Exceeding 5% per position significantly increases ruin risk across normal variance windows.

What is the Fuel Tank Logic for bankroll management?

The Fuel Tank Logic treats a trading bankroll as a finite fuel tank. Every position burns fuel. The goal is not to maximize winnings on a single trade but to stay on the road long enough for your edge to compound. Traders who size by emotion rather than system run dry during normal losing streaks, even when their win rate is positive.

The Fuel Tank Logic.

Your bankroll is a fuel tank. Most prediction market traders drive with the accelerator pinned. Bankroll management - sizing each prediction market position as a fixed percentage of your total capital - is the single practice that separates traders who survive variance from those who blow up mid-season.

Chapter 1

Every position you take burns fuel. The question isn't how much you want to win - it's how long can you stay on the road before you run dry.

The Marcus Breakdown

Friday night. Man City at home. He's confident. Throws $400 on them to win. City win, he's up to $1,280. He feels untouchable.

Saturday. Same confidence. Goes $500 on the next one. Loses. Down to $780. Now he's chasing.

Sunday. Puts $400 on to claw it back. Loses again. Zero.

Three bets. Two wins, one loss. Bankroll: gone. That's what happens when your stake size is decided by your feelings, not a system.

Chapter 2

Stop betting fixed amounts. Start betting fixed percentages.

This one change is the difference between a prediction market trader who's still active in December and one who blew up in October. The bankroll manages itself. You just have to follow the tiers.

New market or pure instinct. Stay alive.

Standard

3-5%

You've done the work. Your bread and butter stake.

Max

The Bottom Line

The sharpest prediction market traders aren't the ones who pick the most winners. They're the ones still standing when everyone else has gone home.

Size small. Stay consistent.
