The Sports Betting Market: Growth, Tiers, and the Hidden Profit Killer

‍

The sports betting industry is a behemoth, shaped by tech innovation, regulatory shifts, and consumer appetites that show no sign of slowing down. Operators range from billion-dollar brands to scrappy upstarts trying to elbow their way into the game. But who’s winning? And where’s the real opportunity hiding?

A look at the numbers paints a clear picture: the industry isn’t just growing; it’s consolidating, with a few dominant players and a long tail of hopefuls. Global sports betting revenue is projected to reach £60.6 billion (US$77.87 billion) in 2025 and is expected to hit £73.9 billion (US$94.99 billion) by 2029, growing at a CAGR of 5.09%. 

If you’re an investor, affiliate, or regulator, understanding the tiers of sports betting operators is key to spotting who’s rising, who’s treading water, and who’s dead in the water.

‍

The Four-Tier League of Sports Betting Operators

The market isn’t one-size-fits-all. Instead, it’s broken down into four clear tiers:

‍

• Tier 1 – Large Global Operators, 7% of the market (59 operators). Think: household names, big budgets, global scale.

• Tier 2 – Established Regional Brands, 10% (81 operators). Strong in local markets, but limited international clout.

• Tier 3 – Growing Mid-Size Operators, 29% (233 operators). Growing quickly but punching up against big spenders.

• Tier 4 – Smaller Operators & New Entrants, 54% (434 operators). Niche players trying to break through the noise.

Even beyond Tier 4, countless micro-operators exist, but they barely move the needle. For now, let’s focus on the players that matter.

‍

The Licensing Game: Compliance or Die

Regulation is the tax of legitimacy. No licence? No business. Here’s how compliance shakes out across the tiers:

‍

• Tier 1: 100% licensed (if you’re big and unlicensed, you’re already in court).
• Tier 2: 100% licensed (regional kings play by the rules).
• Tier 3: 92% licensed (most are serious about scaling and know they need to play nice with regulators).
• Tier 4: 83% licensed (some are rolling the dice, but most see compliance as a must-have, not a nice-to-have).

For operators on the lower end of town, black-hat marketing and aggressive affiliate strategies can seem like a viable workaround, but it’s murky territory. Without a licence, many rely almost entirely on affiliates to drive traffic, creating an unpredictable and often inefficient funnel. Affiliates are a strong channel, but real scale demands a multichannel approach that blends paid, organic, and direct acquisition. As compliance tightens and ad platforms restrict access, unlicensed operators will struggle to grow beyond their affiliate dependency, while legitimate brands cement their market position with a diversified acquisition strategy.

‍

Market Influence: Who’s Really Pulling Traffic?

Website traffic tells you who’s winning the eyeballs and, more importantly, who’s converting them. Here’s the raw data:

‍

• Tier 1: 1.17 billion total visitors, only 261.9 million are unique.
• Tier 2: 342.5 million total visitors, only 85 million are unique.
• Tier 3: 295.7 million total visitors, only 70.3 million unique.
• Tier 4: 74.9 million total visitors, only 21.1 million are unique.

A telling stat: 76.8% of total traffic comes from returning users. Translation? The industry is hooked on repeat customers.

For operators, this raises a key question: Where’s the next wave of customers coming from? If new user acquisition isn’t prioritised, growth stalls, and market share calcifies. Complicating matters, brand campaigns often see existing customers chewing up clicks just to log in, padding media spend without driving fresh acquisition.

‍

Advertising Spend: Why Aren’t Operators Spending More?

For an industry obsessed with user acquisition, ad spend feels oddly restrained. The average Cost Per Acquisition (CPA) sits between $250 and $500 per user, with lifetime value (LTV) ranging from $2,000 to $5,000. The math works until you factor in IVT. Based on averages from our current platform customers, invalid clicks as a percentage of all clicks tell a grim story:

A significant chunk of paid traffic doesn’t come from genuine new users. Bots and returning users navigating directly back to the platform often inflate click volumes, skewing performance metrics and draining budgets. Every dollar wasted on clicks that have no chance of leading to a first-time depositor is a dollar that isn’t bringing in real bettors. With invalid traffic rates in paid acquisition campaigns reaching as high as 40%, operators need to optimise their ad spend with rigorous fraud detection and verification to ensure their budget is fuelling real growth.

‍

The Retention Problem: Betting on the Same Customers

Branded keyword campaigns campaigns are built to reel in fresh bettors, but returning users, repeatedly logging in to place and check bets on a browser, are clogging the clicks and siphoning the budget. Here’s the breakdown of what we see on TrafficGuard’s platform:

• Tier 1: 37% of clicks from returning users; 26% of branded ad spend wasted on them.
• Tier 2: 24% returning user clicks; 14% of budget misfired.
• Tier 3: 33% returning clicks; 27% of spend lost to familiar faces.
• Tier 4: 27% returning users; 15% of budget off-target.

Brand loyalty is a win, but it can throw Google search campaigns off target. Efforts to build a brand - via sponsorships, TV, radio, influencers, and podcasts - are crafted to spark awareness, while branded Google search campaigns aim to turn that interest into active bettors. Yet, existing customers are derailing the plan, using these ads as a quick log-in hack instead of scrolling to the organic listings below. This flood of navigational traffic inflates metrics, muddying the waters of true acquisition success. To top it off, brands are cornered into bidding on their own terms to fend off competitors dangling bonus bets, sniping prospects before they hit the organic results.

‍

IVT Rates: Everyone’s Got a Bot Problem

Tier 1 is eating the internet, but the numbers hide a catch. Invalid traffic (IVT) is the industry’s uninvited guest that no one can escape. Based on customer and prospect data from a 2-week detection audit across over 100 operators’ campaigns, here’s how it shakes out:

• Tier 1, The Titans: 44% IVT click rate. 
• Tier 2, Regional Heavyweights: 29% IVT click rate.
• Tier 3, Mid-Size Contenders: 42% IVT click rate.
• Tier 4, The Underdogs: 33% IVT click rate.

The game isn’t just about attracting traffic. It’s about filtering the noise. Tier 1 might dominate in volume, but smaller operators are losing efficiency, with over half their clicks wasted. Sports betting ad fraud detection isn’t optional. It’s survival.

The industry’s entrenched in a brutal standoff, and though invalid traffic strikes from multiple angles, bots play a sly, supporting role. They’re not the primary menace, but their persistent invasion - lured by generic hooks like “bonus bets”- is a steady drain no operator can shrug off. Some of these bots are craftily scripted for bonus abuse, designed to exploit offers and siphon value. While registration filters often snag them before they cash in, they’ve already taken their toll, chewing through campaign budgets and leaving less for genuine prospects.

Zoom in on generic keyword campaigns, and the threat becomes more precise. That’s where we see the sharpest hits from these automated saboteurs:

These aren’t just bad clicks—they’re missed opportunities. While branded campaigns suffer from navigational traffic, generic campaigns are wide open to exploitation by fraudsters and scripts that know how to game the system. Without proactive protection, campaign performance looks better on the surface than it is in reality. The result? Bloated metrics, misfiring spend, and a distorted view of what’s actually driving conversions.

‍

Where’s the Action? 

Geographically, sports betting operators are concentrated in three key regions:

• Brazil – Dominates all tiers. If you’re not looking at Latin America, you’re missing out.
• United States – A Tier 1 stronghold, but regulatory barriers still complicate growth.
• United Kingdom – A mature market, but mid-tier operators thrive here.
  
  

‍

Brazil’s growing dominance across all tiers signals a clear opportunity: Latin America is the next big battleground. With Brazil recently launching its licensing framework and hundreds of applications already live or in motion, the market is poised for a surge in regulated operators. With an estimated $10 billion in annual betting revenue and a mobile-first audience, the region presents a prime expansion opportunity, but competition will be fierce as new entrants flood the space.

‍

Mobile is King (But Not Everyone Got the Memo)

84% of studied operators have a mobile app. But not all apps are created equal:

• Tier 1: 91.5% have an app (if they didn’t, it’d be malpractice).
• Tier 4: 79.9% have an app (opportunity alert: mobile is their best shot at relevance).

Mobile adoption is nearly universal, but the gaps at the bottom hint at a missed opportunity. The average bettor places 75% of wagers via mobile devices, yet invalid traffic detection in fantasy sports ads remains an issue for smaller operators.

The Takeaways: Where the Smart Money Goes

1. Market dominance is top-heavy. Tier 1 rules, but even they’re wrestling with 44% IVT and 40% wasted ad spend, based on TrafficGuard platform data.
2. Licensing isn’t a differentiator. It’s execution, user experience, and ad fraud prevention that separate winners.
3. New user growth is a problem.
4. Invalid traffic protection is mission-critical. Across tiers, IVT ranges between 29% to 55%.
5. Brazil is the market to watch.
6. Acquisition costs are rising. Optimising CPA means slashing IVT. Tier 2’s 29% IVT and 17% wasted spend is a benchmark to chase.
7. The sports betting market is at a tipping point. Major players are solidifying dominance, but even Tier 1’s 44% IVT and 40% wasted ad spend show no one is untouchable.
8. Smaller operators, especially Tier 4 with 55% invalid clicks and 19% budget loss, are fighting a losing battle unless they adapt.
9. Brazil’s a goldmine, but only for those who can scale without drowning in bots.
10. The smart money doubles down on efficiency, not just volume.

The sports betting market is at a tipping point. Major players are solidifying dominance, but even Tier 1’s 44% IVT, based on our platform averages, shows no one is untouchable. Smaller operators, especially Tier 4 with 55% invalid clicks, are fighting a losing battle unless they adapt. Execution, via seamless mobile UX, smarter acquisition, and relentless fraud prevention, will crown the winners. Brazil’s a goldmine, but only for those who can scale without drowning in bots (6% to 8% of clicks) or recycling users (up to 49%), per our customer data. The smart money doubles down on efficiency, not just volume.
