Best Soccer Arbitrage Platforms in 2026: Where to Place Bets

The quick answer

• Most soccer to bet on: Kalshi. Five big leagues, MLS, Liga MX.

• Most individual markets: Polymarket US. Thousands across the big leagues, and it's MLS's partner.

• Cheapest to use: Novig. No fee before kickoff.

• Listed but slow: ProphetX. Takes minutes to fill on a busy day.

• Closed to US bettors: Betfair, Smarkets, Matchbook, Pinnacle. None accepts US accounts.

• Arb tools: only BetBurger scans both Kalshi and Polymarket US for surebets.

Kalshi and Polymarket US are the only two sites a US bettor can reach with enough soccer liquidity to arb. The exchanges every arbitrage guide recommends, Betfair, Smarkets and Matchbook, refuse US accounts outright. Arbs also appear far less often than the software companies suggest: 19.2% of matches if one bet goes on an exchange, but 0.8% among bookmakers.

What is soccer arbitrage?

Arbitrage, or arbing, means backing every possible result of a match at prices good enough that you come out ahead no matter who wins. You're collecting the difference between two prices, with no view on who wins.

It works because betting sites disagree with each other. If one site prices Arsenal generously and another prices the draw and Chelsea generously, you can back all three and the numbers add up in your favor. The gap is your profit, and the result of the match is irrelevant.

The software companies overstate how often that happens by roughly an order of magnitude.

How we compared the sites

This ranks places a US bettor can open an account and get a soccer bet matched. Three things matter:

• Coverage: which leagues and bet types are listed.

• Depth: whether enough other people are betting there for your bet to fill before the price moves.

• Cost: what the site charges, from its own published schedule, checked on 10 September 2026.

We haven't ranked the arb-hunting software itself. The section on tool coverage below covers which ones reach these sites.

How do the sites compare?

The bottom four are the sites every soccer arbitrage guide tells you to use, and a US bettor cannot open an account at any of those exchanges. Smarkets the company does run a licensed US sportsbook, SBK, in Indiana, but that's a sportsbook, not the exchange the guides mean.

1. Kalshi has the most soccer on the board

Most leagues, and you can get to it through Robinhood.

Kalshi carries the Premier League, La Liga, Serie A, Bundesliga, Ligue 1, the Championship, the Champions League, the Europa League, MLS and Liga MX, with 1,406 soccer-tagged series in total. During the season it runs 20 Premier League matches with 60 markets between them on match results alone, three per match, plus separate series for spreads, totals, both-teams-to-score and goalscorers.

• Three separate bets. Home, draw and away each trade as their own market with their own order book, so you're not forced to take a package.

• $1.75 on a $50 bet at even odds, less on favorites and more on longshots. The fee falls as the price rises, which is the opposite of what most people assume.

• The resting side pays on the marquee markets. A maker fee of up to 44c per 100 contracts applies to the Premier League match-result series but not to its spreads, totals or goalscorer markets. It comes out of whoever is sitting on the other side, not out of your $1.75.

Best for: the bet that needs to fill, especially outside the biggest five leagues.

2. Polymarket US has the most markets

It pays you about 31c to post a price and wait.

Polymarket US runs thousands of soccer markets, with dedicated match pages for the Premier League and MLS covering the winner, handicaps, totals and player bets. MLS named it the Official and Exclusive Prediction Market Partner of MLS, the All-Star Game, MLS Cup and Leagues Cup in January 2026. That's a commercial deal and not proof of depth, though the MLS book carries 271 open events and $22M of volume.

The useful part for arbing: if you name your own price and wait for someone to take it, Polymarket pays you about 31c for it, so the leg you're patient with earns money. Clear $250,000 of taker volume in a month and it refunds 10% of your taker fees, weekly, rising to 50% above $10M. Just check you're on the US site, because the international one won't let US users open new positions.

Best for: the side of the arb you can afford to leave sitting there.

3. Novig costs the least to use

Free before kickoff, available in all but three states.

Novig charges nothing on a straightforward pre-kickoff bet on one result, to either person in the trade. When the average arb is worth 1.4%, paying zero instead of 2% leaves the whole margin with you.

It doesn't publish a league list, so check the app for the match you want. What its own guide does describe are the bet types arbers care about, including Asian handicaps that take the draw out of the equation. That matters, because bookmakers charge roughly 6% to 8% on the standard home-draw-away bet but about 3.6% on the two-way version, so the two-way market is where the value sits.

Two limits:

• The bet-type list is Novig's own. It comes from Novig's marketing, not an independent source.

• It's the newest site here. A Tuesday-night Serie A match won't have the depth an established market would, and on thin markets Novig has said it expects to take the other side itself at spreads of 1% to 4%.

Best for: pre-kickoff bets on the big five leagues, where paying nothing keeps the whole profit.

4. ProphetX lists everything but fills slowly

Everything's listed, but it's marginal for arbing. Charges 2% of net gains.

ProphetX lists all five major European leagues plus MLS, along with the English Championship, League One, Eliteserien, Brazilian Série A and Argentinian Primera. It takes 2% of your net gains in a market on straight trades, with nothing when you lose. There is no Champions League market as of 10 September 2026.

Depth is the problem. ProphetX is an order book, and its own documentation says an order fills instantly only up to the cash resting at that price: beyond that it partially fills and the rest sits waiting. Arbing needs both legs to land within seconds. On a thin Saturday soccer book, that's a real risk.

Best for: patient soccer betting. Too slow to arb.

Which arb software covers these sites?

The two US-reachable sites with enough depth are Kalshi and Polymarket US. The three best-known arb tools handle them differently:

• BetBurger covers both, inside its scanner. It added Polymarket in November 2025, prematch only at first, with live following in January 2026, and Kalshi in June 2026 in both modes. Soccer is its biggest Polymarket category, at 45% of prematch surebets and 52% of live ones as of 11 September 2026.

• OddsJam covers both, but not in its arbitrage tool. Its Prediction Traders product tracks Kalshi, Polymarket, ProphetX and Novig, and says 88% of its signals are sports-related. Its actual arbitrage scanner lists no prediction-market books at all.

• RebelBetting covers neither. Its exchange coverage is Betfair, Betdaq, Matchbook and Smarkets, and all four refuse US customers.

So the tool most guides recommend for US bettors, RebelBetting, watches four exchanges you can't open an account at. If you want a conventional surebet scanner pointed at venues you can use, BetBurger is the one that gets there today.

What this guide can't tell you

• Nobody knows how long an arb lasts. You'll see three minutes, or fifteen, or thirty seconds. Every one of those numbers comes from a company selling arb software. There is no independent measurement.

• The research isn't live conditions. The Economica study used one price snapshot per match from 2004 to 2011, recorded Friday afternoons for weekend fixtures. Treat 19.2% and 0.8% as the shape of the market. This weekend's hit rate could be anything.

• Most measured arbs aren't takeable anyway. In the study covering the 2012/13 season, roughly half the arbitrage portfolios required backing the favorite at a bookmaker the study describes as restricting such customers, and dropping one outlier bookmaker cut 545 opportunities to 287.

• Depth on the US sites is unpublished. No soccer volume data exists for Kalshi, Polymarket US, Novig or ProphetX, so "enough to fill" is a judgment call.

Where can you actually use these?

As of 10 September 2026:

• Novig: works everywhere except Arizona, Michigan and Nevada.

• ProphetX: says it's nationwide and publishes no state list. Nevada is blocked in practice.

• Kalshi: sports markets blocked or restricted in Nevada, Michigan, Utah, Washington, Massachusetts, Maryland and Ohio, disputed in Arizona and about seven other states.

• Polymarket US: covers most states.

All of this is unsettled. Two federal appeals courts have ruled and they disagree: the Third Circuit sided with Kalshi against New Jersey in April 2026, the Ninth Circuit sided with Nevada on 28 August 2026. Four more circuits are still weighing it, and New Jersey has asked the Supreme Court to resolve the split. Smarkets and Matchbook are both applying for CFTC designation, so the closed door at the bottom of our table may not stay closed. Check before you deposit.

Soccer arbitrage FAQ

What platforms give the best soccer arbitrage?

For a US bettor, Kalshi and Polymarket US, because they're the only two with both enough soccer depth and legal access in most states. Novig is the cheapest to use, charging nothing before kickoff. The exchanges usually recommended for soccer arbing, Betfair, Smarkets and Matchbook, don't accept US customers.

How often do soccer arbs actually appear?

Between a bookmaker and an exchange, a study of 11,933 top-league matches found a guaranteed profit in 19.2% of them, using a short-position strategy. Among ten bookmakers, which is closer to what most arb software looks at, 0.8% of 12,782 matches. The average one was worth 1.4% after fees.

Can I use Betfair for soccer arbitrage from the US?

No. Betfair's terms name the United States a Prohibited Territory. Its only US exchange product, a New Jersey horse racing exchange, closed on 1 October 2020. Smarkets and Matchbook also refuse US accounts on their exchanges, though both are applying for CFTC designation.

Which soccer leagues are best for arbitrage?

The big ones. Grant and colleagues counted opportunities across seven bookmakers, combining home-draw-away and Asian handicap prices, so their rates run far above the ten-book figure above: across the 2012/13 season arbs appeared most often in the Bundesliga at 30.72% of matches and least often in the Dutch Eredivisie at 18.63%. More bookmakers competing on a league means tighter prices and more disagreement between them. The English fifth tier costs roughly twice as much to bet into as the Premier League, which wipes out the gap before you can take it.

Do arb scanners cover Kalshi and Polymarket?

Two of the big three do. BetBurger added Polymarket in November 2025 and Kalshi in June 2026, and soccer is its largest Polymarket category. OddsJam tracks both in its Prediction Traders product, though not in its arbitrage scanner. RebelBetting covers neither, and the four exchanges it does cover all refuse US customers.
