    How to Scrape Betting Odds from Multiple Bookmakers

    Scraping betting odds from bookmakers is one of the most technically demanding forms of web scraping. Bookmakers use cutting-edge anti-bot technology, serve odds through complex JavaScript frameworks, update prices every few seconds, and actively detect and block automated access. Yet the data is enormously valuable for odds comparison, market analysis, trading models, and research.

    This guide provides a detailed, technical walkthrough for scraping odds from major bookmakers, with specific strategies for each platform and practical proxy configurations.

    Bookmaker Landscape: Know Your Targets

    Major International Bookmakers

    Bookmaker Base Primary Tech Stack Scraping Difficulty Best Proxy Type
    Bet365 UK React, WebSocket 10/10 Mobile (UK)
    Pinnacle Curacao React, REST API 5/10 Mobile (any)
    Betfair Exchange UK Angular, REST API 6/10 Mobile (UK/IE)
    William Hill UK React, WebSocket 8/10 Mobile (UK)
    1xBet Curacao Custom framework 6/10 Mobile (varies)
    Betway Malta React 7/10 Mobile (EU)

    Asian Bookmakers

    Bookmaker Base Primary Tech Stack Scraping Difficulty Best Proxy Type
    Sbobet Philippines Custom, AJAX 7/10 Mobile (SEA)
    Maxbet/IBCBet Philippines Custom 6/10 Mobile (SEA)
    M88 Philippines HTML + AJAX 5/10 Mobile (SEA)
    W88 Philippines HTML + JS 5/10 Mobile (SEA)
    188bet Isle of Man React 6/10 Mobile (SEA/UK)
    12BET Philippines HTML 4/10 Mobile (SEA)
    Fun88 Philippines Custom 5/10 Mobile (SEA)

    Asian bookmakers are particularly important because they often set the market for football (soccer) odds. Sharp bettors and trading firms watch Asian lines closely because they tend to move first.

    DataResearchTools mobile proxies cover all major Southeast Asian markets, making them ideal for scraping Asian bookmakers that require regional IP addresses.

    Technical Approaches by Bookmaker

    Bet365: The Hardest Target

    Bet365 is widely considered the most difficult bookmaker to scrape. Their anti-bot measures include:

    • Custom JavaScript obfuscation that changes frequently
    • WebSocket-based odds delivery
    • Advanced browser fingerprinting
    • Geographic IP verification
    • Behavioral analysis (mouse movements, scroll patterns)
    • Device attestation

    Approach: Full Browser Automation

    Critical notes for Bet365:

    • Use non-headless browsers (or undetectable headless setups)
    • Mobile proxies from the UK are essential since Bet365 verifies geographic location
    • Rotate browser profiles, not just IPs
    • Limit sessions to 15-20 minutes before creating a new one
    • DataResearchTools mobile proxies with UK endpoints provide the geographic authenticity Bet365 requires

    For Sbobet, a Southeast Asian mobile proxy is essential. Sbobet restricts access based on geographic location and is primarily accessible from Asian IP addresses. DataResearchTools Thai, Indonesian, and Philippine mobile proxies provide the geographic authenticity needed.

    Betfair Exchange: Unique Data Source

    Betfair is a betting exchange, not a traditional bookmaker. Its odds are set by the market (bettors against each other), making it a unique data source.

    Approach: Official API (Preferred)

            "notes": "Standard SEA bookmaker. Moderate protection."
        }
    }

    Handling Common Scraping Challenges

    Challenge 1: Dynamic Content Loading

    Many bookmakers load odds asynchronously after the initial page load:

    async def wait_for_odds(page, timeout=10000):
        """Wait for odds to appear on the page"""
        try:
            await page.wait_for_selector(
                "[class*='odds'], [class*='price'], [data-odds]",
                timeout=timeout,
                state="visible"
            )
            # Additional wait for all odds to stabilize
            await page.wait_for_timeout(2000)
        except TimeoutError:
            print("Odds did not load within timeout")
            return False
        return True

    Challenge 2: Odds Format Differences

    Asian bookmakers often display odds in Malay, Hong Kong, or Indonesian format:

    Format Favorite Underdog Example
    Decimal 1.85 2.10 European standard
    American -118 +110 US standard
    Hong Kong 0.85 1.10 HK = Decimal – 1
    Malay 0.85 -0.91 Neg = inverse
    Indonesian -1.18 1.10 Inverse of Malay

    Challenge 3: Market Matching

    The same event appears differently across bookmakers. Matching events requires fuzzy matching:

    from fuzzywuzzy import fuzz
    
    def match_events(event_a, event_b, threshold=85):
        """Determine if two events from different bookmakers are the same"""
        # Compare team names
        home_score = fuzz.ratio(
            event_a["home"].lower(),
            event_b["home"].lower()
        )
        away_score = fuzz.ratio(
            event_a["away"].lower(),
            event_b["away"].lower()
        )
    
        # Check if start times are close (within 5 minutes)
        time_diff = abs(
            (event_a["start_time"] - event_b["start_time"]).total_seconds()
        )
        time_match = time_diff < 300
    
        # Both team names must match well, and time must be close
        return (home_score >= threshold and
                away_score >= threshold and
                time_match)

    Challenge 4: Geographic Restrictions

    Some bookmakers are only accessible from specific countries. DataResearchTools mobile proxies solve this by providing genuine mobile IPs from the required regions:

    Bookmaker Accessible Regions DataResearchTools Coverage
    Sbobet Southeast Asia Thailand, Indonesia, Philippines, Malaysia, Vietnam
    M88 Asia Full SEA coverage
    W88 Asia Full SEA coverage
    Bet365 UK, EU, select others UK endpoints available
    Betfair UK, Ireland, Australia UK endpoints available

    Monitoring and Maintenance

    Health Checks

    class ScraperHealthMonitor:
        def __init__(self):
            self.metrics = {}
    
        def record_scrape(self, bookmaker, success, duration, records_count):
            if bookmaker not in self.metrics:
                self.metrics[bookmaker] = {
                    "total_scrapes": 0,
                    "successful": 0,
                    "failed": 0,
                    "avg_duration": 0,
                    "total_records": 0
                }
    
            m = self.metrics[bookmaker]
            m["total_scrapes"] += 1
            if success:
                m["successful"] += 1
                m["total_records"] += records_count
            else:
                m["failed"] += 1
    
            # Running average
            m["avg_duration"] = (
                (m["avg_duration"] * (m["total_scrapes"] - 1) + duration)
                / m["total_scrapes"]
            )
    
        def get_health_report(self):
            report = {}
            for bookmaker, m in self.metrics.items():
                success_rate = m["successful"] / max(m["total_scrapes"], 1) * 100
                report[bookmaker] = {
                    "success_rate": f"{success_rate:.1f}%",
                    "avg_duration": f"{m['avg_duration']:.1f}s",
                    "total_records": m["total_records"],
                    "status": "healthy" if success_rate > 90 else "degraded" if success_rate > 70 else "failing"
                }
            return report

    Conclusion

    Scraping betting odds from multiple bookmakers is a complex but achievable task when you combine the right tools. Each bookmaker requires a tailored approach: Bet365 demands full browser automation with UK mobile proxies, Pinnacle offers relatively accessible API-like endpoints, and Asian bookmakers like Sbobet require Southeast Asian mobile IPs.

    DataResearchTools mobile proxies provide the geographic coverage and IP quality needed to access bookmakers across both European and Asian markets. Their Southeast Asian carrier network is particularly valuable for scraping the Asian bookmakers that professional bettors rely on for sharp pricing.

    Start with the easiest targets (Pinnacle, smaller Asian books), build your normalization pipeline, and then tackle the harder bookmakers as your infrastructure matures. The odds data you collect will power comparison tools, arbitrage detection, market analysis, and predictive models that create genuine competitive advantage in the sports betting ecosystem.

    Proxies for Arbitrage Betting: Multi-Account Management Guide

    Arbitrage betting, often called “arbing” or “sure betting,” is the practice of placing bets on all possible outcomes of an event across different bookmakers to guarantee a profit regardless of the result. It works because bookmakers occasionally disagree on the probability of outcomes, creating small pricing gaps that can be exploited.

    The challenge is that bookmakers actively hunt for arbitrage bettors and will limit or close accounts that display arbing patterns. Managing multiple bookmaker accounts while avoiding detection requires sophisticated proxy infrastructure. This guide explains the entire process.

    How Arbitrage Betting Works

    The Basic Concept

    Arbitrage opportunities arise when the combined implied probability of all outcomes across different bookmakers falls below 100%:

    Example: Tennis Match

    Outcome Bookmaker A Odds Bookmaker B Odds
    Player 1 wins 2.10 1.80
    Player 2 wins 1.75 2.20

    Calculate implied probabilities:

    • Bookmaker A, Player 1: 1/2.10 = 47.62%
    • Bookmaker B, Player 2: 1/2.20 = 45.45%
    • Total: 47.62% + 45.45% = 93.07%

    Since the total is below 100%, an arbitrage opportunity exists. The potential profit margin is:

    Profit = (1 – 0.9307) x 100 = 6.93%

    Stake Calculation

    For a total investment of $1,000:

    • Stake on Player 1 (Bookmaker A at 2.10): $1,000 x (45.45% / 93.07%) = $488.37
    • Stake on Player 2 (Bookmaker B at 2.20): $1,000 x (47.62% / 93.07%) = $511.63
    Outcome Payout Profit
    Player 1 wins $488.37 x 2.10 = $1,025.58 $25.58
    Player 2 wins $511.63 x 2.20 = $1,125.59 $125.59

    Guaranteed minimum profit: $25.58 on a $1,000 investment.

    Why Bookmakers Hate Arbers

    Arbitrage bettors extract guaranteed profit from the market without taking any risk. From the bookmaker’s perspective:

    1. Lost margin: Every arb erodes the bookmaker’s theoretical margin.
    2. Sharp money signal: Arb activity often coincides with sharp line movements.
    3. Resource consumption: Arbers make many small, time-sensitive bets that stress systems.
    4. No recreational value: Arbers do not engage with promotions or make losing bets.

    Why Proxies Are Essential for Arbitrage Betting

    How Bookmakers Detect Arbers

    Bookmakers use multiple detection methods:

    Detection Method What They Track How Proxies Help
    IP correlation Multiple accounts from same IP Isolate each account to its own proxy
    Betting patterns Consistent arb-sized stakes Proxies alone do not solve this; behavioral changes needed
    Timing analysis Bets placed simultaneously across books Proxies add latency variation
    Account linking Shared payment methods, addresses Not a proxy issue; operational security
    Device fingerprinting Browser, OS, hardware identifiers Proxy + anti-detect browser needed
    Geographic inconsistency IP location vs. registration address Geo-targeted proxies solve this

    The Multi-Account Requirement

    Successful arbitrage betting requires accounts at 10-30+ bookmakers. Many arbers also maintain backup accounts for when primary accounts get limited. Without proxies:

    • Logging into multiple bookmaker accounts from the same IP links them together
    • If one account gets flagged, all linked accounts may be investigated
    • Geographic inconsistencies between your IP and account registration raise flags

    Setting Up Proxy Infrastructure for Arbing

    Proxy Requirements

    Requirement Why Solution
    Dedicated IP per account Prevent cross-contamination Sticky mobile proxy sessions
    Geographic matching IP must match account country Country-specific proxy endpoints
    High uptime Arbs disappear in seconds Premium proxy provider with SLA
    Low latency Speed matters for arb execution Regional proxy servers
    Mobile IPs Highest trust score Mobile proxy provider

        def register_account(self, bookmaker, account_id, proxy_config):
            """Permanently assign a proxy to a bookmaker account"""
            key = f"{bookmaker}:{account_id}"
            self.account_proxies[key] = {
                "proxy_url": f"http://{proxy_config['user']}:{proxy_config['pass']}@{proxy_config['host']}:{proxy_config['port']}",
                "country": proxy_config["country"],
                "assigned_at": datetime.now(),
                "last_used": None,
                "request_count": 0
            }
    
        def get_proxy(self, bookmaker, account_id):
            """Get the assigned proxy for this account"""
            key = f"{bookmaker}:{account_id}"
            proxy_data = self.account_proxies.get(key)
    
            if not proxy_data:
                raise ValueError(f"No proxy assigned for {key}")
    
            proxy_data["last_used"] = datetime.now()
            proxy_data["request_count"] += 1
    
            return proxy_data["proxy_url"]
    
    
    # Setup example
    proxy_manager = ArbProxyManager()
    
    # Each bookmaker account gets its own dedicated proxy
    proxy_manager.register_account("bet365", "user_001", {
        "host": "gate.dataresearchtools.com",
        "port": "5001",
        "user": "arb_user_1",
        "pass": "arb_pass_1",
        "country": "GB"
    })
    
    proxy_manager.register_account("pinnacle", "user_002", {
        "host": "gate.dataresearchtools.com",
        "port": "5002",

    })

        "pass": "arb_pass_3",
        "country": "TH"  # Thai proxy for Asian bookmaker
    })

    Multi-Account Management Best Practices

    Account Registration

    When creating bookmaker accounts for arbing:

    1. Use the proxy from registration onward: The first IP a bookmaker sees becomes part of your account fingerprint. Never register through your home IP.
    2. Match proxy country to your identity documents: If your ID shows a Thai address, use a Thai mobile proxy.
    3. Complete KYC promptly: Delayed KYC can flag an account for review.
    4. Use realistic registration details: Fill in all optional fields (phone, address) to appear legitimate.

    Session Management

    class BookmakerSession:
        def __init__(self, bookmaker, account_id, proxy_manager):
            self.bookmaker = bookmaker
            self.account_id = account_id
            self.proxy = proxy_manager.get_proxy(bookmaker, account_id)
            self.session = requests.Session()
            self.session.proxies = {
                "http": self.proxy,
                "https": self.proxy
            }
            self.session.headers.update(self.get_headers())
    
        def get_headers(self):
            """Return consistent headers for this account"""
            # Each account should have a fixed, realistic fingerprint

    Behavioral Guidelines

    Even with perfect proxy isolation, your betting patterns can expose you:

    Bet Sizing

    • Do not always bet exact arb-calculated stakes (e.g., $487.32)
    • Round stakes to natural amounts ($490, $500, $485)
    • Vary your stakes slightly between bets
    • Occasionally place small recreational bets that are not part of arb strategies

    Timing

    • Do not place both legs of an arb within seconds of each other
    • Add random delays between bookmaker interactions
    • Avoid betting exclusively on events where arbs exist
    • Log in and browse without betting sometimes

    Account Activity

    • Use bookmaker promotions and bonuses (but read the terms carefully)
    • Place some pre-match bets that look recreational
    • Engage with the bookmaker’s app or site beyond just betting
    • Maintain a natural ratio of wins to losses on individual accounts

    Anti-Detect Browser Setup

    For browser-based bookmaker access, pair your proxy with an anti-detect browser:

    Anti-Detect Browser Key Features Price Range
    Multilogin Browser profiles, fingerprint management $99-399/month
    GoLogin Cloud profiles, team sharing $49-199/month
    AdsPower Free tier available, good for beginners Free-$50/month
    Dolphin Anty Popular in arb community $71-239/month

    Configuration per profile:

    • Assign one DataResearchTools mobile proxy per browser profile
    • Set timezone to match proxy location
    • Configure language to match proxy country
    • Use consistent canvas and WebGL fingerprints
    • Enable cookie persistence between sessions

    Finding Arbitrage Opportunities

    Manual Scanning

    Check odds comparison sites like:

    • OddsPortal
    • Oddschecker
    • BetBrain

    Calculate the arb percentage manually or use a spreadsheet formula.

    Risk Management

    Partial Execution Risk

    The biggest risk in arbing is when one leg gets placed but another fails (odds moved, account limited, site down). Mitigation strategies:

    1. Always check odds immediately before placing: Stale odds are the primary cause of failed arbs.
    2. Set minimum acceptable odds: Reject the bet if odds have moved more than 2% from the scanned value.
    3. Place the less liquid leg first: Start with the bookmaker most likely to move odds or reject the bet.
    4. Have hedging plans: If one leg fails, immediately check if you can hedge on another bookmaker.

    Account Limitation Management

    When a bookmaker limits your account:

    Limitation Type Impact Response
    Stake limit reduction Max bet lowered Scale down arbs on that book
    Market restriction Some markets unavailable Remove from arb scanner for those markets
    Account closure No more betting Switch to backup account via different proxy
    Withdrawal hold Funds temporarily locked Document everything, contact support

    Proxy Failure Handling

    class ProxyFailoverManager:
        def __init__(self, primary_proxies, backup_proxies):
            self.primary = primary_proxies
            self.backup = backup_proxies
            self.failed_primaries = set()
    
        def get_proxy(self, account_key):
            if account_key not in self.failed_primaries:
                proxy = self.primary.get(account_key)
                if self.test_proxy(proxy):
                    return proxy
                self.failed_primaries.add(account_key)
    
            # Failover to backup
            return self.backup.get(account_key)
    
        def test_proxy(self, proxy_url):
            try:
                response = requests.get(
                    "https://api.ipify.org",
                    proxies={"http": proxy_url, "https": proxy_url},
                    timeout=5
                )
                return response.status_code == 200
            except:
                return False

    Cost Analysis

    Expected Returns

    Monthly Turnover Average Arb % Gross Profit Net After Costs
    $10,000 2.5% $250 Variable
    $50,000 2.5% $1,250 Variable
    $100,000 2.0% $2,000 Variable
    $500,000 1.5% $7,500 Variable

    Note: Returns depend heavily on the number of arbs found, execution speed, and account longevity. The proxy investment directly impacts account longevity by reducing detection risk.

    Conclusion

    Arbitrage betting with proxies is a systematic approach to extracting guaranteed profits from bookmaker pricing inefficiencies. The proxy infrastructure is not optional; it is the foundation that determines how long your accounts survive and how many bookmakers you can operate across simultaneously.

    DataResearchTools mobile proxies provide the trust score, geographic targeting, and sticky session capabilities that arbing demands. Their Southeast Asian carrier coverage is particularly valuable for accessing Asian bookmakers like Sbobet, M88, and W88, which frequently offer sharp odds that create arb opportunities with European books.

    The key to long-term arbing success is discipline: one proxy per account, geographic consistency, natural betting patterns, and immediate response to account limitations. Invest in quality proxy infrastructure from the start, and you will extend your account lifetimes significantly, which is the single biggest determinant of arbing profitability.
