Conclusion

Arbitrage between Web2 and Web3 is a systematic trading tool. It requires discipline, an understanding of how the platforms work, and a willingness to manage risks. The trading terminal handles the technical aspects: search, calculation, navigation, and liquidity monitoring. Your task is to oversee execution.

How Web2 and Web3 Markets Work + The Ins and Outs of Working with Bookmakers

Arbitrage between traditional bookmakers and decentralized prediction markets differs fundamentally from classic surebets. It’s not just about finding differences in odds. It involves operating at the intersection of two independent financial ecosystems. Let’s break down why this combination offers an advantage, how to minimize bookmakers’ attention, and what to do with your capital when withdrawal limits apply.

The Ins and Outs of Working with Bookmakers

Although there is no direct monitoring, bookmakers analyze account behavior based on internal statistics. To reduce the likelihood of restrictions, follow these rules:

Avoid betting at the maximum limits; your bet amounts should match the profile of a regular player.
Diversify your markets. Don’t focus solely on totals, handicaps, or political outcomes. Spreading your activity across different event types reduces the suspicion of a pattern.

Maintain natural intervals between bets. Placing bets on all available markets instantly looks like the work of a script for automated systems. Try to bet amounts that are multiples of $5 or $10 (e.g., $40, $45, or $50). Bets with fractional amounts (such as $43.78) look unnatural and may attract unnecessary attention from the bookmaker.

Practical Tips
Start with small amounts to get a feel for the speed of placing bets and understand how the platforms work
Always check that the odds are up to date before placing a bet—markets can change in a matter of seconds
Take fees into account: withdrawal fees, conversion fees, and network fees in DeFi

How the Scanner Works

Setting Up Filters
After logging into the terminal, you set your search parameters: minimum return on investment (ROI), sports, bankroll limits, maximum bet amounts, and event type. This filters out unprofitable opportunities and leaves only those that fit your bankroll.

Monitoring the feed
Arbitrage opportunities appear in real time. Each card displays: bookmakers, odds, calculated amounts for each leg, net ROI after fees, and time until the event starts.

Opening positions
When you click on an arbitrage opportunity, the terminal opens the relevant bookmaker pages in adjacent tabs. You simultaneously place two bets for the calculated amounts.

How much capital is needed
Recommended starting capital: $100–200 for comfortable trading with low limits.
It is not recommended to risk more than 20–30% of your bankroll on a single arbitrage opportunity.

Potential income
Income is generated not by predicting outcomes, but through mathematical calculation. Actual figures:
Average spread on arbitrage opportunities: 5%, in rare cases up to 30–50% in illiquid markets
Number of suitable arbitrage opportunities per hour: from 1–2 to more than 10 during periods of high volatility
Actual monthly ROI with active trading: over 30% of working capital

Important: Income depends not only on the availability of arbitrage opportunities but also on execution speed, bankroll size, discipline in adhering to limits, and accounting for commissions. The terminal displays the estimated profit before placing bets—this allows you to assess profitability before entering a position.

Web2 Bookmakers
Traditional platforms offering deep liquidity and a wide range of sports markets. Ideal for generating stable turnover

Web3 Bookmakers
Platforms operating at the intersection of DeFi and sports betting. Next-generation platforms that enable instant transactions via crypto wallets and require no verification, which directly impacts processing speed.

The terminal handles the search, calculations, and navigation. You work only with ready-made betting combinations and monitor their execution. All that’s left is to lock in your profit

Understanding the Scanner's Features and How It Works

The terminal operates in real time. It continuously retrieves odds from bookmaker lines and prediction markets. The main technical challenge is to match events that are formatted differently across various platforms. The algorithm matches opposing outcomes of the same event, calculating the “arbitrage” profit.

If the combined odds assessment allows for a guaranteed profit regardless of the match outcome, the scanner instantly adds the event to the feed for processing. The entire cycle, from receiving the odds to the appearance of the surebet in the terminal, takes a fraction of a second

Overview of Platforms

Prediction Markets
A decentralized prediction market. Prices are determined by traders based on expectations, liquidity, and macro narratives.

The absence of the traditional “margin call” model makes them a priority for long-term trading, and their unique pricing often results in significant spreads relative to traditional betting lines.

[Subline @Subline_arb]

Where does the profit come from?

Your profit is a mathematically guaranteed gain resulting from the difference in how the probability of the same event is assessed on different platforms. You’re not predicting the outcome. You’re betting on the difference. It’s pure mathematics, not luck.

If you have any questions, we’d be happy to answer them.

Subline welcomes you

We’re kicking off a short series of posts about our service so you can better understand how the product works

To start, let’s go over the basics

[Subline @Subline_arb]

Where does the spread come from?

The spread arises due to market inefficiencies. The spread exists because Polymarket and bookmakers are different markets with different pricing mechanisms:
Polymarket is a decentralized prediction market. Prices are formed by traders based on expectations, liquidity, crypto narratives, and speculative flows.

Bookmakers are commercial entities. They set margins and respond to betting volumes, risk models, regulatory constraints, and news events.

Differences in audience, reaction speed, fees, and algorithms lead to temporary misalignments. It is these “windows” that we capture.
