Most people treat "crypto sports betting" and "prediction markets" as the same thing. They are not. One is a sportsbook that accepts USDC instead of Visa. The other is a market structure where you trade on outcomes. If you want to understand the structural difference before diving in, this breakdown of how prediction markets work is a good starting point. The difference matters more than most newcomers realize.
Right now, the line between the two is blurring fast. Decentralized protocols are replacing the house. On-chain resolution is replacing referees in call centers. Liquidity is flowing from offshore books into smart contracts. If you want to bet on the Super Bowl or a Champions League final with crypto, your options in 2025 are genuinely different from what existed two years ago.
We put together this list to cover the full spectrum. Some of these are centralized sportsbooks that accept crypto. Some are fully on-chain protocols. Some sit in between. We ranked them on actual utility: available markets, decentralization, payout transparency, and how well they work for a crypto-native user. If you are already familiar with the landscape, our roundup of the best prediction market platforms covers the broader category beyond sports. Here is what we found.
1. Polymarket — The prediction market everyone is actually using
What it is: Polymarket is a USDC-based prediction market on Polygon where users trade YES/NO shares on real-world outcomes. It covers sports, politics, economics, and crypto events. It is not technically a sportsbook, but sports markets draw some of its largest trading volumes.
Why it matters: Polymarket resolves markets using UMA Protocol's optimistic oracle, which means resolution is transparent and publicly disputable. For sports outcomes, that means no ambiguity about who pays out. You can watch the resolution process happen in real time. It also means anyone can create a market, which has produced a long tail of niche sports events you would never find on a traditional book. Polymarket is also one of the clearest examples of on-chain prediction markets in DeFi done at scale.
Key features:
USDC-denominated, no native token required
On-chain order book with public trade history
Community-created markets, not just curated events
Mobile-friendly interface with real-time odds
The catch: Liquidity on smaller sports markets can be thin. You will not move meaningful size on a Bundesliga relegation market without slippage. The big political and crypto markets are liquid. Many sports markets are not.
2. Azuro Protocol — The infrastructure layer for decentralized sports betting
What it is: Azuro is an open-source protocol that provides the backend infrastructure for decentralized sports betting apps. Developers build front-ends on top of it. Multiple interfaces, one shared liquidity pool. Think of it as the Uniswap of sports prediction.
Why it matters: Because Azuro separates the liquidity pool from the user interface, liquidity aggregates rather than fragments. When you bet on an Azuro-powered app, you are tapping the same pool as every other app built on the protocol. That is a structurally different approach from every centralized crypto book, and it matters for odds quality.
Key features:
Shared liquidity across all front-end apps
30,000+ live and pre-match sports markets
Deployed on Gnosis Chain and Polygon
Open SDK for developers to build on top
The catch: You are always one layer removed from the protocol itself as an end user. The app you interact with is a third-party front-end, not Azuro directly. Quality and UX vary between them.
3. Overtime Markets — Decentralized sports markets with on-chain AMM pricing
What it is: Overtime Markets is built on Thales, which runs on Optimism and Base. It uses an AMM model to price sports outcomes instead of a traditional order book. You trade against the protocol's liquidity, not other users.
Why it matters: AMM-based sports markets are a genuinely interesting design. Pricing is algorithmic and transparent. You can verify exactly how the odds are set. For a crypto-native user who wants to understand what they are actually paying for in a spread, that is a meaningful improvement over a black-box sportsbook. It is also worth understanding the cost structure of on-chain derivatives before committing size to AMM-priced markets.
Key features:
AMM pricing, no counterparty needed
sUSD and USDC collateral support
Parlay functionality on-chain
Native integration with Thales governance
The catch: AMM pricing means the market cannot always reflect true probability accurately, especially for major events. You may get better odds on Polymarket for the same outcome. The protocol is also still relatively small. Total liquidity is a fraction of what centralized books handle daily.
4. Stake.com — The dominant centralized crypto sportsbook
What it is: Stake is a centralized crypto casino and sportsbook that processes an enormous volume of wagers. It accepts Bitcoin, Ethereum, and a range of altcoins. It is licensed in Curacao and operates globally except in a few restricted jurisdictions.
Why it matters: Stake has built a product that is genuinely competitive with traditional sportsbooks on market depth, odds, and live betting. If you want broad sports coverage and fast withdrawals in crypto, Stake is the benchmark that decentralized protocols are measured against. Its affiliate program and influencer partnerships have driven mainstream crypto adoption into sports betting in a way no protocol has matched.
Key features:
40+ sports covered, including esports
Live betting with in-play markets
Crypto deposits and withdrawals, typically fast
VIP program with reload bonuses
The catch: Centralized. Fully custodial. You do not control your funds once they are deposited. No on-chain resolution. You are trusting the company, not the blockchain.
5. Rollbit — Crypto sportsbook with a native token economy
What it is: Rollbit is a crypto casino and sportsbook with a native token, RLB, that gives holders a share of the platform's revenue. Rollbit has grown aggressively through leveraged trading features alongside its sports product.
Why it matters: The RLB buyback mechanism is a real attempt to connect platform revenue to a token economy. When the house wins, RLB holders see value returned to them through burns. That is a different incentive structure than a pure utility token. It has attracted a crypto-native user base that is interested in both the betting product and the tokenomics.
Key features:
Sports betting, casino, and futures trading in one interface
RLB revenue-sharing via buyback burns
Crypto-native UX with NFT integrations
Live chat and community features built in
The catch: Still centralized. The token economy adds complexity and speculative risk on top of already speculative betting. Not for users who want clean, simple prediction market exposure.
6. Cloudbet — One of the longest-running crypto sportsbooks
What it is: Cloudbet launched in 2013, making it one of the earliest Bitcoin sportsbooks still operating. It covers a wide range of sports, esports, and virtual sports. It accepts Bitcoin, Ethereum, USDC, and a growing list of altcoins.
Why it matters: Longevity in crypto is rare. Cloudbet has survived multiple bear markets, regulatory shifts, and the rise of dozens of competitors. That track record matters when you are trusting a custodial platform with your funds. It also has one of the better interfaces for traditional sports bettors transitioning to crypto.
Key features:
Bitcoin deposits and withdrawals since 2013
Sports, esports, and virtual sports
Competitive odds on major leagues
Multi-language support and global access
The catch: The UX feels older than most competitors. The bonus structure is complex and tied to long wagering requirements. No on-chain resolution or transparency about how odds are set.
7. SX Bet — The decentralized peer-to-peer sports exchange
What it is: SX Bet is a peer-to-peer prediction exchange built on the SX Network, an Ethereum sidechain. Users set their own lines and match against each other. There is no house. The exchange takes a small fee on matched bets.
Why it matters: Removing the house changes the math fundamentally. On a traditional sportsbook, the vig is built into every line. On SX Bet, you are trading against another person who has their own opinion on the outcome. In theory, the aggregate price discovery should be more accurate. In practice, it depends on whether there is enough liquidity to match your position. If you are approaching this as an investment strategy rather than pure gambling, how to invest in prediction markets covers the key frameworks.
Key features:
Peer-to-peer order book, no house edge
Deployed on SX Network with low fees
DAI and USDC supported
API access for programmatic betting
The catch: Liquidity is the real constraint. Niche events may not attract counterparties at all. You can set a line, but if nobody takes the other side, you have no bet. The product works well for major North American sports. Less so for global football.
8. Betswap.gg — Aggregator for decentralized sports prediction
What it is: Betswap aggregates liquidity from multiple decentralized protocols into a single interface. You connect your wallet and access markets from different underlying protocols without switching between apps.
Why it matters: Fragmentation is one of the biggest problems in decentralized sports prediction. Liquidity is spread across Azuro, Overtime, SX, and others. An aggregator that routes your bet to the best available price and deepest pool is a real value-add. Betswap is attempting to be that layer.
Key features:
Multi-protocol liquidity aggregation
Wallet-connected, non-custodial
Cross-chain support across Polygon, Gnosis, and others
Single interface for multiple underlying protocols
The catch: The aggregator model is only as good as the underlying protocols. If liquidity is thin on every protocol it connects to, routing across them does not solve the problem. It just makes the thin liquidity slightly easier to access.
9. Augur — The original decentralized prediction market
What it is: Augur is one of the first Ethereum-based prediction market protocols, launched in 2018. It allows anyone to create and trade on any outcome. Sports, politics, crypto prices, anything. REP token holders serve as reporters to resolve disputed markets.
Why it matters: Augur proved that fully decentralized, permissionless prediction markets were technically feasible. Everything that came after it learned from what worked and what did not. The resolution mechanism using REP token stakers was an early attempt at credibly neutral dispute resolution. It is not the dominant market today, but it remains a reference point for protocol design.
Key features:
Fully permissionless market creation
REP-based dispute resolution
Long track record on Ethereum mainnet
Open protocol, no single operator
The catch: Augur suffered from low liquidity, a confusing UX, and slow resolution times. It was technically impressive and commercially underperforming. Augur v2 improved on several dimensions, but it has been largely displaced by Polymarket for active users.
10. Pinnacle — The sharpest crypto-accepting sportsbook
What it is: Pinnacle is a traditional sportsbook with a decades-long reputation for the lowest margins and accepting winning bettors. It is not a crypto-native product, but it accepts Bitcoin for deposits and withdrawals. Serious bettors use it for odds quality.
Why it matters: Pinnacle's margins are routinely the lowest in the industry. Typical overround on major markets runs around 2%, compared to 5-10% at most competitors. For a crypto user who actually cares about expected value, Pinnacle's odds quality can outweigh the lack of native crypto integration. It is also one of the few books that does not ban or limit sharp bettors. One more thing worth knowing before you start profiting: how prediction market winnings are taxed varies significantly by jurisdiction, and it applies to sportsbooks and protocols alike.
Key features:
Industry-low margins on major sports
Welcomes sharp and high-volume bettors
Bitcoin deposits and withdrawals
Deep liquidity on mainstream sports
The catch: Not decentralized in any meaningful sense. Centralized custody. No on-chain resolution. Geographically restricted and not available in many markets. Accepts crypto as a payment rail, not as a philosophical commitment.
Where This Is All Heading
The split between centralized crypto sportsbooks and decentralized prediction protocols is not a temporary phase. It reflects a real tension in what users want. Centralized platforms offer liquidity depth, broad market coverage, and a polished experience. Decentralized protocols offer custody, transparency, and credibly neutral resolution. Right now, most users are choosing convenience. That is changing.
What this list reveals is that the infrastructure for truly on-chain prediction markets is maturing fast. Azuro, Overtime, SX, and Polymarket have each solved different pieces of the problem. Resolution without human involvement is technically solved. Liquidity aggregation is being worked on. The UX gap between a good CEX sportsbook and a decentralized protocol is narrowing every cycle.
At Hedgehog, we are watching this closely because it confirms the core thesis. Markets work best when resolution is transparent, automatic, and tied to real data. Sports prediction markets are learning that lesson from the outside in. Hedgehog is applying it to the data that lives entirely on-chain: funding rates, gas fees, base fees, and every other metric that the blockchain generates in real time. Previously opaque system variables become liquid markets. When one window ends, a new one starts. That is the direction everything is moving.
