What is a qualifying bet?

The cash bet a sportsbook requires before it gives you a promotion, such as the first bet in a "bet $50, get $200" offer.

What is a qualifying loss?

The small amount you lose when you hedge a qualifying bet so the result does not matter. It is set by the combined margin of the two prices you used: stake × d₁ × margin.

What is a good qualifying loss?

Around 1–2% of the qualifying stake near even money is good and usually needs the best price on each side at different books. Around 9% means you used a standard −110/−110 market.

Can a qualifying bet make money?

Occasionally the two best prices cross, and the pair becomes a small arbitrage. That is uncommon and short-lived; plan on a small loss.

Qualifying bets: unlocking a promotion for the least money

A qualifying bet is the bet you must place to unlock a promotion. Hedged, it costs a small fixed amount — the qualifying loss — and how small depends almost entirely on the market's margin.

A qualifying bet is the real-money bet a sportsbook requires before it releases a promotion: "bet $50, get $200 in bonus bets" makes the $50 bet the qualifying bet. In matched betting you hedge it at another book so the result does not matter, and it costs you a small, fixed amount called the qualifying loss. On a tight pair of prices near even money that loss can be 1–2% of the qualifying stake; on a standard −110/−110 market it is about 9% of the stake (4.55% of the total staked across both bets). The skill is choosing the market.

Why it costs anything

Both bets are cash, and both books build a margin into their prices. When you cover every outcome, you pay the combined margin of the two prices you chose. That margin is the overround: add up the implied probabilities of the two sides, and whatever is above 100% is the cost. It works out to a neat formula: qualifying loss = stake × d₁ × (1 ÷ d₁ + 1 ÷ d₂ − 1), where d₁ is your qualifying bet's decimal odds and d₂ the hedge's. Our hold and vig guide explains the margin itself.

The same $500 qualifying bet on two markets

Market 1: −110 / −110: 1.9091 / 1.9091, overround 4.76%
Hedge: 500 × 1.9091 ÷ 1.9091: $500.00
Either outcome: −$45.45
Market 2: +105 / −108: 2.05 / 1.9259, overround 0.704%
Hedge: 500 × 2.05 ÷ 1.9259: $532.21
Team A wins: $525.00 − $532.21: −$7.21
Team B wins: $532.21 × 0.9259 − $500: −$7.21
Saved by choosing the market: $38.24

Market 2 is two different books' best prices on each side — which is exactly what low hold searches for. Illustrative prices; tight pairs like this come and go.

Is the promotion worth the qualifying loss?

Compare what you pay to unlock it with what the reward converts to. A $7.21 qualifying loss to unlock $200 of bonus bets that convert at 70% ($140) is an easy yes. A $45 qualifying loss to unlock a $25 bonus bet is a no. Where a promotion requires a large rollover — wagering several times a bonus before withdrawing — the qualifying loss applies to every dollar of that turnover, and market choice becomes the whole question.

When the terms set minimum odds

Same $500 stake, same 0.704% overround: cost scales with d₁
Qualifying bet at +105 (d₁ = 2.05): 500 × 2.05 × 0.007036 ≈ $7.21
Qualifying bet at +200 (d₁ = 3.00): 500 × 3.00 × 0.007036 ≈ $10.55
Qualifying bet at +400 (d₁ = 5.00): 500 × 5.00 × 0.007036 ≈ $17.59

Holding the margin fixed isolates the effect of the odds; in practice longer-odds markets also tend to carry wider margins, which widens the gap further. If an offer demands a minimum price, bet as close to that minimum as the terms allow.

Keeping the qualifying loss small

1Read the terms for minimum odds, eligible markets and whether the bet must settle before the reward is issued.
2Look at main-line markets in major leagues first: moneylines, spreads and totals in the NFL, NBA, MLB and NHL are where books compete hardest and margins are tightest.
3Take each side at the book with the best price. The two legs are almost always at different books.
4Stay near even money if the terms allow it. The loss formula multiplies by d₁, so a qualifying bet at long odds costs more for the same margin.
5Size the hedge with H = stake × d₁ ÷ d₂ and check both outcomes land on the same number.
