Return on Investment (ROI)
The percentage return on total amount wagered. An ROI of +5% means you've profited 5 cents for every dollar bet. Calculated as (profit / total wagered) × 100.
Like measuring a business's profitability by profit margin, not just revenue — it's about what you keep relative to what you invest.
Why it matters
ROI is the truest measure of betting performance — it accounts for volume and tells you whether your edge is real over a meaningful sample.
How DMP uses this
DMP tracks ROI on graded research candidates to measure model performance over time, providing transparency on the platform's model accuracy page.
Common mistake
Confusing ROI with win rate — you can win 60% of bets and still have negative ROI if your losses are bigger than your wins.
