Betting is Bigger Than You Think

Betting is a massive global phenomenon, with over $1 trillion wagered annually. Fueled by rapid mobile adoption, rising incomes, and the constant draw of instant gratification, online betting has grown at breakneck speed.

In fact, the sports betting market alone is expected to hit $250 billion, with estimates suggesting 1 billion active bettors, roughly one in eight humans worldwide, by 2030.

And yet, despite being one of the most liquid, high-frequency, and global markets, traditional betting is full of issues.

• Predatory House: Centralized bookmakers rake a 10-20% cut, making long-term profitability nearly impossible.
• Lack of Transparency: Odds are set behind closed doors, with no way to verify fairness. Funds sit in custodial “black boxes,” vulnerable to hacks and fraud.
• Slow payouts. Winners often wait days, weeks or even longer to get paid.
• Limited markets. Bettors can only wager on what the house chooses to offer.

The house doesn’t just win—it’s engineered to. But crypto is changing this centuries-old model, replacing hidden odds and steep fees with transparent on-chain ledgers and self-custodied funds.

The Crypto Betting Revolution: Power to the Players

For the past decade or so, the online betting world has undergone a bundling phase. Major platforms like DraftKings, Betway, and Bet365 have realised that gamblers want two main things:

1. Liquidity: the bigger the pool of money, the greater the betting options and potentially higher payouts.
2. Trust: players feel safer with recognised brands that (at least publicly) follow licensing requirements and have large budgets for marketing and customer support.

This bundling approach thrived because it gave bettors a convenient, all-in-one destination to bet on sports, play digital casino games, or join poker tournaments.

Now, with crypto’s robust infrastructure—from decentralised liquidity pools to on-chain order books—betting is undergoing an unbundling. Trust can be baked directly into smart contracts, payouts can settle instantly on public ledgers, and participants can transparently verify each bet’s fairness. In other words, instead of relying on a single, centralised casino for liquidity, distributed networks can provide it.

• Instant, Smart Contract-Settled Payouts: Platforms using smart contracts can deliver winnings directly to your wallet the very instant an event settles, bypassing the usual wait times of traditional casinos.
• Provably Fair Odds & Market-Made Liquidity: On-chain order books allow anyone to verify how odds are set and updated, removing the “black box” effect. Polymarket’s decentralised prediction markets illustrate how open order books create fair pricing and deeper liquidity.
• Player-Owned Economies: Many crypto betting platforms launch their own tokens. Users who stake or hold these tokens can become co-owners of the platform’s liquidity pool, participating in revenue sharing rather than simply losing to the house.

This shift toward decentralised, specialised betting experiences means players get more choice, transparency, and control. Rather than entrusting a single massive operator with all your funds and wagers, you can pick and choose from different on-chain platforms—each focusing on what they do best, be it sports pools, prediction markets, esports matches, or casino games. In short, by eliminating middlemen, liquidity, trust, and fairness are becoming features of the protocol itself, finally giving bettors an edge in a market traditionally dominated by the house.

The Crypto Wagering Market Map

Wagering spans a continuum,from skill-based competitions to luck-driven casino games,here’s an in-depth look at the five key verticals and how they are evolving:

1.Skill-Based Betting: Wager on Your Talent

Instead of betting on external events, you bet on yourself. Let’s say you are a good Counter-Strike player and grind 1 hour daily with your team. To make it more interesting, you can stake $5 on your team’s ability to outplay opponents.

Players who want to bet on their own gameplay generally turn to ‘skin gambling’ sites and deposit cosmetic in-game items before getting paired. However, these sites are shady and lack transparency and fair play protections. Past controversies forced Valve to shut down support for such sites.

Key Players:

• @showdown_gg: Infrastructure for peer-to-peer esports wagers. Showdown’s smart contracts lock up both sides’ funds while game validation nodes report match results for automated payouts. Showdown supports rating-based matchmaking across CS2, Dota, Lichess, and is working on adding more games.

Showdown’s on-chain architecture

• @hqtrivia: Revived on-chain, this platform from the Vine founders could use crypto for skill-based trivia contests, rewarding winners with instant token payouts.

Innovations: Transparent Rating Systems and on-chain algorithms prevent rigged outcomes. No centralised intermediaries, smart contract escrow, and instant player-driven payouts.

2.Casual Social Betting (Low-Stakes, High-Fun)

For many, gambling is more about fun with friends rather than serious profit. Whether you’re crunching the data or just going with your gut, it’s a quick, entertaining bet. Casual sports or esports wagers with friends—like predicting a final score or a specific in-game event such as ‘first goal scorer’—dominate this category.

For example, one could bet on the final score of a Manchester United versus Manchester City match. The outcome depends on factors like each team’s form, individual player performance, and potential injuries. Well-informed fans can leverage past statistics to improve their odds of guessing the correct score.

Even if they’re not betting real money, players often form fantasy league teams to compete with friends—another way to show off their expertise and enhance the fun without the financial stakes.

Interestingly, ARPU data shows people often bet more when they feel knowledgeable (e.g., analysing their favourite soccer team).

Most apps use betting pools for every match, listing the odds for each potential score. Users simply pick the final tally they believe will occur, and payouts are determined by those odds once the match concludes.

Key Players:

• @BetDEXLabs: Focuses on community-driven sports pools, leveraging Solana’s speed for instant, transparent payouts.
• @BetSwirl: Integrated with Farcaster, making it easy to bet along with friends.
• @RareBetSports: A sports betting platform on Monad, wagers on basketball, tennis and football with near-zero rakes.

Innovations:

• House Edge Removal: Rakes drop to 0-2%, letting players keep more of their winnings.
• Decentralised Liquidity: Users pool funds, effectively becoming the “house”.
• Social Integration: Betting happens within chatting apps, cutting user friction.

3.Prediction Markets: Crowdsourced forecasting

Why stop at sports or gaming? Prediction markets let you wager on real-world events: elections, corporate earnings, weather, Oscars or even AGI breakthroughs.

These markets tap the wisdom of the crowd for potentially more accurate forecasting than traditional polls or closed-door bookmakers. In a market like Polymarket, you’re effectively buying and selling “shares” tied to event outcomes, each priced between $0.00 and $1.00 USDC. There’s no “house” to bet against; you’re trading directly with other users.

For instance, if Miami is listed at an 18% chance of winning a game, you can purchase “Yes” shares at $0.18 each. If Miami does win, each of those shares pays out $1, netting you an 82-cent profit per share. “No” shares become worthless.

You’re not locked into your trade; as new information emerges—like an injury to a star player or a major political shift—the demand for each outcome fluctuates, and share prices move to reflect these ever-evolving odds.

Key Players:

• @Polymarket: The poster child for on-chain prediction markets, exploded in 2024 with $100M+ wagered on the U.S. elections. Built on Polygon for transparency and speed.
• @Kalshi: CFTC-approved prediction market.
• @opinionsdotfun: Transforms commentary into betting markets. Anyone can launch prediction markets based on a topic introduced by a KOL, and the KOL earns platform fees generated by this market.

Innovations:

• No Withdrawal Limits: Bettors can stake as much as they want, unlike regulated platforms.
• Verifiable Odds: Users shape odds through decentralised order books and can create diverse markets.

4.Casino Gambling: High-Stakes, Luck-Based Thrills

This category fuses classic casino action—slots, roulette, dice—with high-leverage speculation, sometimes bundling sports, esports, and even crypto futures all under one roof. Stake, for example, was among the first to recognize the benefits of crypto payments, letting users deposit and withdraw digital assets with ease. Another heavyweight is Rollbit, which ties platform revenues to its native token through buybacks, forging strong community ties and landing major sponsorships with Southampton Football Club and Faze CS.

That said, the crypto-casino space has become increasingly crowded, as even mainstream gambling sites now accept crypto. Established platforms also tend to run their own sportsbooks, creating massive liquidity pools that can be tough for newcomers to match.

Key Players:

• @rollbit: Crypto casino with leveraged trading, and tokenised revenue sharing via $RLB.
• @betfury_gaming: A decentralised casino platform focusing on slots and table games, ensuring fairness via smart contracts.
• @TGCasino_: Integrates Telegram for frictionless casino betting, leveraging crypto for instant withdrawals.

Innovations:

• Provably Fair RNG: On-chain algorithms guarantee no behind-the-scenes tampering.

• Token Buybacks & Revenue-Sharing: Users can own a slice of the casino’s profits.

5.Infra & Middleware

Core protocols that ensure reliable data, fair settlement, and developer-friendly tooling.

Key Players:

• @azuroprotocol: Azuro is a decentralised protocol for prediction markets on EVM chains, tooling & infrastructure for powerful betting interfaces, facilitating $300M+ volume across 43 apps.

• @HedgehogMarkets: Quick-launch prediction markets, powering projects like @pumpscience in the DeSci ecosystem.
• AI Agent Sportsbooks (e.g., @DKING, @Billybets): Automated bots that analyse data and place bets, effectively functioning as “autonomous sportsbooks.”. For a deeper dive into this emerging sector check out @0xJeff’s piece on GambleFAI.

These protocols will power the next generation of on-chain wagering, ensuring liquidity, transparency, and automated settlement.

Final Thoughts

Crypto fundamentally changes the gambling experience in four key ways:

1. Fast, Private Payments: Established players like Stake show how frictionless crypto deposits and withdrawals beat old banking rails.
2. Fair & Open Pools: Polymarket-style open wagers, where anyone can create markets and verify the underlying math.
3. Easy P2P Wagering: Protocols like Showdown let you match up directly with opponents, removing the house’s cut.
4. Own the Casino: Platforms like Shuffle and Betswirl distribute profits to token holders through buybacks or staking, converting players into co-owners.

As stablecoins become more widespread, we believe on-chain wagering to explode in popularity.

That said, regulatory challenges loom large. Polymarket’s U.S. restrictions highlight the complex legal patchwork worldwide. And given past skin-betting controversies, responsible gaming measures remain crucial to prevent underage betting and exploitation.

Crypto is rewriting the rules of a trillion-dollar market, offering trust, speed, and user ownership like never before. In a space historically stacked in favour of the house, the GambleFi revolution will finally give the edge back to the players.
