Are casino numbers and lottery sales linked?
The relationship between casinos and lottery ticket sales is a topic of public policy, behavioural economics, and consumer spending. When policymakers consider expanding commercial or tribal gaming, one of the primary concerns is cannibalization, the theory that dollars spent at casino slot machines and gaming tables will be diverted away from lottery products.
Research and historical market data show that the answer to whether more casinos yield higher lottery sales is nuanced: casinos generally do not increase lottery sales, but neither do they cause a complete collapse of lottery revenues. Instead, the two gambling mediums cater to distinct consumer motivations, demographics, and behavioural impulses, resulting in a complex mix of localized substitution, market saturation, and complementary spending.
A look at the impact
To evaluate how casinos impact lottery sales, economists analyze two competing hypotheses. The Cannibalization (Substitution) Hypothesis sees gambling budgets as finite. When a brick-and-mortar casino opens in a region, consumers redirect discretionary entertainment income away from lower-margin products like scratch-offs or draw games toward immersive casino experiences. The Expansion (Complementary) Hypothesis says the introduction of new gaming venues normalizes gambling across the population, lowering moral or social stigma. This increased exposure creates a broader culture of risk-taking, subtly encouraging non-gamblers or casual players to purchase lottery tickets during routine errands.
In practice, economic studies indicate that the substitution effect predominates on a localized level, while macro-level trends show that lottery sales often continue growing due to population growth, product innovation, and multi-jurisdictional jackpot hype.
Why don't casinos completely eradicate lottery sales, or vice versa? The answer lies in how these two forms of gaming are structured and consumed.
| Feature | Lotteries | Brick-and-Mortar Casinos |
|---|---|---|
| Accessibility | High (Convenience stores, gas stations, grocery lines) | Low to Moderate (Requires travel, dedicated destination visit) |
| Price Point | Low barrier to entry ($1 to $30) | Higher initial stake (Buy-ins, bankrolls, secondary travel costs) |
| Payout Structure & Odds | Low Return to Player | High Return to Player |
| Pacing & Feedback | Delayed feedback (Draws) or quick scratch-off | Instant, continuous sensory feedback (Slots, tables) |
| Social Dynamics | Solitary, convenience-driven transaction | Social, entertainment destination (Dining, shows, nightlife) |
Because a $2 lottery ticket purchased while buying gasoline fulfills a quick "life-changing dream" impulse, it rarely competes directly with a planned $200 weekend trip to a casino resort.
While total lottery sales may appear resilient following casino expansion, a closer examination reveals distinct impacts on different lottery product lines. Scratch-off products share structural similarities with electronic gaming machines (EGMs) or slot machines, namely immediate gratification and low-to-moderate ticket prices. Consequently, scratch-off sales suffer the highest degree of localized substitution when regional casinos open nearby. Multi-jurisdictional draw games operate almost entirely independently of casino presence. Demand for these games is driven primarily by jackpot size. When a jackpot surpasses $500 million or $1 billion, casual players flood retail stores regardless of how many casinos exist in their area.
For policy makers, relying on gambling for public revenue creates a delicate balancing act. Lotteries return a significantly higher margin to regulator treasuries compared to commercial casino taxes.
If a new casino cannibalizes $100 million in lottery scratch-off sales, the regulator loses approximately $30 million in direct public funding. To break even on tax revenue, that same casino must generate a much larger overall volume of gaming spend. As casino markets reach geographic saturation across North America, the incremental revenue generated by building additional regional casinos continues to diminish over time.
The results
Building more casinos does not translate to an increase in lottery ticket sales. While the expansion of commercial gaming does not completely extinguish lottery participation due to differing player habits and convenience access, it introduces direct competition for discretionary gambling dollars. In most mature gaming markets, casino expansions lead to mild revenue erosion or stagnation in traditional lottery products—particularly instant tickets—while mega-draw lottery sales remain tied to jackpot size rather than venue availability.
