Sports events are the fastest-growing category on prediction markets. But 97% of participants lose money — because they trade without a system. We fix that.
Sportsbooks build a 4–10% margin directly into every set of odds. That's before you place a single bet. In 2024, Americans wagered $148.7 billion on sports — sportsbooks kept $13.6 billion. For every dollar bet, the average bettor loses 7.7 cents. Only about 3% of regular bettors report profits after one year. Worse: sportsbooks actively limit or ban winning accounts.
Exchanges remove the house entirely — you trade against other participants. The platform takes 2–5% commission on net winnings only, not on every bet. No built-in odds margin, no winner discrimination. Roughly 40% of exchange users achieve profitability vs. about 3% at traditional sportsbooks. A massive structural improvement — but most participants still lack the discipline to manage risk properly.
Platforms like Kalshi are CFTC-regulated financial exchanges — not gambling sites. CNN and the Wall Street Journal use their data. The Federal Reserve studies their forecasting accuracy. But a CEPR analysis of 300,000+ Kalshi contracts found a clear favourite-longshot bias: contracts priced under 10¢ lose over 60% of invested capital. The median user loses about 7% of their balance within 90 days. Cheap "lottery ticket" contracts are the biggest trap.
The pattern is clear: each level up reduces structural disadvantage — but no platform solves the behavioural problem. Chasing losses (52% of bettors do it). Oversizing positions on binary events. No idea what the Kelly criterion is. Treating uncorrelated contracts like a single bet instead of a portfolio. The same risk management that keeps investment portfolios alive works here. Position sizing. Fractional Kelly. Diversification across uncorrelated events. Drawdown limits.
The same analytical discipline that runs financial portfolios — applied to event contracts and prediction markets.

Club narratives from Akte Bundesliga. Scandals, near-misses, improbable champions. Hertha BSC ready first.
Most corrupt, controversial moments in World Cup history. 25-part series. Mussolini's dinner. Escobar's murder.
A single event contract is a coin flip. A portfolio of uncorrelated positions across sports, politics, and macro events — with Kelly-optimal sizing — is an investment strategy. The same diversification logic that works for stocks works here.
