Betting Bankroll Kelly Risk

Winning sports betting isn’t about “picks.” It’s capital allocation under uncertainty. Your edge comes from disciplined stake sizing, portfolio construction across markets, strict drawdown control, and relentless price selection. This guide consolidates advanced bankroll principles into a practical framework you can execute consistently.

Define your bankroll

  • Separate bankroll from life money: Keep betting capital isolated (own accounts, own tracking).
  • Liquidity is king: Prefer funds available within hours, not days. Avoid lockups unless compensated.
  • Denominate in base currency: Minimize FX risk. If multi-currency, track consolidated value.
  • Set rules up front: No top-ups after losses; planned injections only (e.g., quarterly).

Unit sizing that respects variance

  • Base case: 0.5–1.5% of bankroll per standard bet depending on edge confidence.
  • High variance markets: Use smaller units (e.g., player props, longshots, parlays avoided).
  • Cap exposure: Daily cap 5–10% across all bets; single-event cap 2–3% unless hedged.

Fractional Kelly for durability

Kelly optimizes long-term growth but is fragile under estimation error. Use fractional Kelly on conservative edge estimates.

  • Kelly stake: f = (bp - q) / b where b = odds - 1, p = win probability, q = 1 - p.
  • Fractional policy: 0.25–0.50 Kelly on vetted models; 0.10–0.25 on qualitative edges.
  • Bound stakes: Hard cap at 2% per bet even when fractional Kelly suggests more.

Portfolio allocation

  • Market mix: 50–70% core markets (sides/totals), 20–40% derivatives (alts, props), 0–10% experiments.
  • Diversify books: Spread action across reputable books and exchanges for better prices and limits.
  • Uncorrelated exposures: Avoid stacking outcomes that rise/fall together unless you explicitly model covariance.

Drawdown control

  • Soft stop: At −5% weekly, cut stake size by 25–50% and review.
  • Hard stop: At −10% monthly, halt new positions; conduct post-mortem before resuming.
  • Move down automatically: If bankroll drops 15–20%, reduce base unit by the same proportion.

Line value (CLV) tracking

  • Track fair vs. taken vs. close: Your edge shows up in price improvement more reliably than short-term results.
  • Thresholds: Aim for consistent 1–2% CLV on sides/totals; smaller but steady on props.
  • Operational habit: Always price shop before placing any stake. Treat price as product.

A practical sizing framework

  1. Estimate fair probability (model/market-implied adjusted for edges).
  2. Compute fractional Kelly using conservative inputs.
  3. Apply caps (per-event, per-day, max 2% rule).
  4. Round stakes sensibly to look natural and avoid attention.
  5. Log the bet with model notes and rationale for future review.

Handling futures and long-duration bets

  • Exposure caps: Limit futures to 10–20% of bankroll; ladder entries rather than single shots.
  • Carry cost: Account for time value and liquidity loss; demand higher edge for lockups.
  • Hedge policy: Predefine when to hedge (price targets, injury news) and when to let ride.

Fees, limits, and cash management

  • Prefer books/exchanges with low fees and fast withdrawals.
  • Track limits per market and adjust stake plans to avoid forced small sizes.
  • Consolidate idle balances; don’t leave capital stranded in low-utility accounts.

Execution playbook

  • Pre-session: Update bankroll, review open bets, check schedule and markets to target.
  • In-session: Price shop, size via fractional Kelly, respect caps, and record instantly.
  • Post-session: Update results, CLV metrics, and note process improvements.

Psychology and process

  • Kill tilt with rules: No chase bets; stick to unit and cap policies.
  • Routine: Fixed times for review and execution prevent impulsive decisions.
  • Feedback loops: Weekly review of CLV and errors; monthly strategy check.

Quick templates

Unit sizing

  • Default: 1% per standard bet; high variance markets: 0.5–0.8%.
  • Cap per day: 8% total exposure unless hedged.

Kelly (fractional)

  • Model edges: 0.25–0.50 Kelly; qualitative edges: 0.10–0.25 Kelly.
  • Always cap at 2% regardless.

Worked example

Fractional Kelly sizing

Market price: +110 ⇒ b = 1.10

Estimated win probability: p = 0.58; q = 0.42

Kelly: f = (bp - q) / b = (1.10 × 0.58 − 0.42) / 1.10 ≈ 0.116

At 0.25 Kelly ⇒ stake ≈ 2.9% → cap to 2% by policy

If CLV confirms your edge, consider laddering smaller re-entries on later price improvements within daily caps.

When to resize units

  • Upward: Bankroll grows 25%+ and process quality holds (CLV good).
  • Downward: Drawdown 15–20% or process concerns (CLV deteriorates).
  • Review quarterly regardless; adjust conservatively.

Responsible play

  • Know regional rules and platform terms; stay compliant.
  • Lock in data hygiene and secure devices; protect accounts.
  • Pause if emotional; process beats impulse.

Summary

Professional bankroll management balances growth and durability. Use fractional Kelly on conservative edges, cap exposures, track CLV, and run a disciplined portfolio across markets. Review regularly, resize prudently, and treat price selection and record-keeping as core skills.
