ArbBets Review: Find Arbitrage Opportunities in Prediction Markets

Prediction market arbitrage is a strategy within prediction markets where traders profit from pricing mismatches across multiple platforms offering the same market.

ArbBets is one of the emerging prediction market tools designed to simplify this process by scanning markets for inefficiencies that are difficult to spot manually. It helps identify potential arbitrage opportunities and estimate profitability in real time. Below, we’ll break down how ArbBets works, what arbitrage trading is, and how to use this tool effectively and safely.

What Is Prediction Market Arbitrage?

Prediction market arbitrage, or arbitrage betting, is when you trade on two or more positions in a way that ensures profit. This is typically done by playing two platforms off of each other. For example, there could be a profit to be had by trading on one contract at Kalshi and the opposite at Polymarket. This is also done with standard sports betting, too, playing one sportsbook off another.

The idea isn’t to pick which team will win, for example, but rather to find scenarios in which, no matter the outcome, there’s a built-in profit for you.

How Does Arbitrage Work in Prediction Markets?

Arbitrage in prediction markets is all about finding pricing differences and mistakes across platforms to find low-risk opportunities to walk away with some profit. Again, the idea isn’t to necessarily guess the outcome of the event in question accurately, but to structure trades so you win regardless of the outcome.

At prediction market platforms, each contract has a probability, and if you’re able to locate the same market across two platforms in which the “Yes” and “No” add up to less than $1, there’s profit to be had.

For example, if you’re looking at Kalshi and Polymarket and the same event has “Yes” priced at $0.40 and “No” is priced at $0.55, they add up to $0.95. This is important because you’ll be paid out $1 per contract on the correct side, so this setup allows for a built-in $0.05 profit per contract.

There are many types of prediction market arbitrage in addition to “Yes” and “No” pricing, such as finding sports markets where there’s an opportunity to trade on a team making the championship game and on a team winning it. For this to succeed in an arbitrage setting, the team would need to make the championship, but if they do, these markets logically connect.

For example, if a team has a “Yes” value of $0.40 to reach the championship and the “No” on winning the championship is $0.50, together, these add to $0.90 and there’s profit there because if they make the finals and win, you’ll get $0.10 per contract; if they make the finals and lose, you’ll receive a $1.10 profit.

While this sounds simple, it can get complicated due to many factors:

• Fees could eat into the arbitrage edge.
• Spread and slippage costs, meaning when your order goes through, it could be at a worse price than expected, reducing or eliminating any profit.
• There could be liquidity issues, meaning there isn’t enough volume to fill the position you took.
• These opportunities can go away within seconds due to bots locating them and acting.
• The two platforms you have in mind may have different definitions of what it means to settle a contract.

As for executing on arbitrage trading, there are a few things to keep in mind:

• Limit Orders: Let the market come to you. Only trade at a certain price, and if it happens, great; if not, pass.
• Speed: Be ready to act quickly, as these opportunities can dry up fast.
• Sizing: You’ll need ample volume to make it worth it,t as the edge will already be razor-thin.
• Leg Risk: While some contracts may trade immediately, others can lag, and that could harm the edge you thought you found.
• Exit Plans: If something goes awry, having an exit plan is something to keep in mind. This could include selling and taking the small hit, adjusting limit orders, taking the adjusted price, canceling the trades, and more.

A tool like ArbBets exists to help with the speed aspect of things so that you can spot these inefficiencies and hope to capitalize on them.

What Is ArbBets?

ArbBets is a tool for traders in prediction markets to use that scans markets for price mismatches. The goal is to identify potential for arbitrage trading and to show estimated returns on investment.

This tool is best for active traders who use multiple platforms and also seek out these types of edges, and want to use a tool to help find these inefficiencies. That said, keep in mind that you’ll need to be aware of and confirm liquidity across the various platforms, the fees, and that the trades execute.

How Does ArbBets Work?

To get started at ArbBets, you’ll first need to create an account. You can use it by using your standard email or by connecting your Google account. I opted to connect my Google account, and I was immediately brought to the homepage.

In the upper-right corner, you can click on your account icon,n and there, you’ll find links to Tools, Cross Market Arbitrage, Prediction Markets Screen, Sportsbook Arbitrage, and more.

The tools here include Prediction Markets Screen, Futures Arbitrage, Sportsbook Arbitrage, and Prediction Markets Data. To access these tools, you must have a paid membership to ArbBets; more on the pricing model later.

However, at the top, there’s a menu where you’ll find “Free Arbitrage,” and this will provide some options for free, including Prediction Markets Arbitrage, ArbBets API, and Sports Arbitrage.

Under Prediction Markets Arbitrage, there was one market available, and it showed the pricing for “Will Islam Makhachev be the UFC Welterweight Champion on December 31, 2026?”

It showed Kalsshi had “Yes” at $0.66 and “No” at $0.30. It also showed the spread, profit, and to the right, there was a calculator tool which showed a field for your investment, maximum investment, ROI, Net PNL, and also showed fees across the platforms.

However, if you don’t have a paid membership, this pricing plans page continuously opens. In the Calculator, there’s a link directly to the page on that platform for you to quickly open and trade on.

Why Use ArbBets for Arbitrage Trades?

ArbBets, as a tool, helps streamline the arbitrage process immensely. Tools such as this are helpful because these opportunities come and go quickly, and they can help you quickly find them. Manually scanning for these is almost impossible due to how many markets there are.

From there, it’s also difficult to do the math quickly enough to see if it would be worth it.

Ultimately, the idea behind these tools is speed. It saves the trader time, finds opportunities quickly, does all of the math, and allows the trader to focus more on execution and risk control than research.

How To Use ArbBets

As a beginner, here’s how to use ArbBets at first:

• Scan the availability opportunities ArbBets has found that have a decent edge, not just a percentage or two.
• Check the markets, Kalshi and Polymarket, to ensure these markets exist and the prices are accurate.
• Check the liquidity to see if there’s enough volume to fill the position you want to trade on. ArbBets may find a profitable trade, but you need to ensure you’re able to get the size and/or price you want.
• Set your limit orders and let the market come to you. While arbitrage trading is about being quick, being accurate and precise is important, too.

After you make the trades, keep an eye on them to ensure they fill properly. Nothing is safe until everything is locked in.

Who Is ArbBets For?

ArbBets is the type of tool that can be used for numerous types of traders:

• Active Traders: This tool will be great for traders who are active and always looking for new opportunities.
• Multi-Platform Traders: If you’re open to trading on multiple platforms, this tool will allow you to utilize both accounts.
• Advanced Traders: Experienced traders who want to build a repeatable process to find inefficiencies consistently and not just one-offs or here-and-there.
• Quant/Arb-Style Traders: Traders who want to identify and execute high-frequency, yet small-edge opportunities across various markets.

If you’re brand new to prediction markets, a casual trader, only use one platform, or are someone looking for quick cash, this tool may not exactly be for you. This tool involves being active and understanding risk.

Tips for Arbitrage Trading With ArbBets

When you use ArbBets, here are some tips to use it effectively:

• Focus on markets that’ll get filled. This includes high liquidity, which allows trades to execute and tight spreads with a lower cost to enter.
• Don’t worry about opportunities with tiny edges, like 1% or 2%, because fees will eat into profits.
• Act quickly, but always make sure you’re ready with the contract wording to enter the right market.
• Use limit orders to avoid overpaying or getting bad fills. Remember, yes, you want to be fast, but you want the prices to be beneficial.
• Make sure you track both legs to ensure they both fill and that they’re at the prices you expected.
• When you first get started, focus more on learning how to execute arbitrage trading opportunities. Wait until you understand fill speed, slippage, and how each platform behaves.
• Use a checklist to ensure the price is accurate and the edge is real, confirm the fees, assess liquidity to determine whether the market will be filled, review how both markets settle, and check the entry/exit costs.

Mistakes to Avoid

When you engage in arbitrage trading, you may have an idea of how it’ll go, but here are mistakes to avoid:

• Never assume you’ll always make a profit.
• Don’t ignore fees.
• Don’t overlook execution slippage.
• Be careful of thin markets where you cannot trade on both sides.
• Don’t get stuck with only filling one side.
• Don’t move slowly.
• Don’t go into any trade without an exit plan.

Safety & Risks to Know

Arbitrage trading can be a great way to generate some margin and winnings, but you have to be safe and know the risks.

• Make sure you’re trading on official platforms, like Kalshi, Polymarket, or something of that level.
• Don’t click on random links on social media.
• If you’re linking things like Aan PI, check to see what permissions you’re allowing.
• Attempting to do arbitrage trading isn’t risk-free; trades don’t always execute properly.
• Partial fills can happen.
• Liquidity can disappear, whether there’s not enough volume or other traders pulling orders.
• Tools can be a bit behind due to latency, so always be sure to double-check quickly.
• Use strong passwords and 2-factor authentication on platforms.

Final Verdict — Should You Use ArbBets?

If you’re a more experienced trader with some background in arbitrage trading and you understand the terminology, ArbBets will be valuable to you. This isn’t exactly a tool for a casual trader or someone looking to make a quick buck. You also need to be confident in your abilities to invest in the subscription model that unlocks the rest of the tools.

I recommend using ArbBets primarily to find high-liquidity, high-edge arbitrage setups, but also make sure you confirm fees and that each side of the market can fill before you execute your trades.
