Three brokers make this list, in this order: BetInAsia (BLACK) for the deepest Asian handicap coverage plus Polymarket and Kalshi markets folded into the same betslip, MadMarket (Edge) for exchange access and crypto-first funding, and Sportmarket (Pro) for commission-free pricing and the simplest account setup. They are not interchangeable. If you mostly bet sides and totals with the occasional flutter on an election market, BetInAsia is the strongest single account. If you live by getting matched on an exchange, MadMarket is the sharper tool. If you just want fair pricing across a wide spread of books without learning a new interface, Sportmarket gets there with the least friction. The breakdown below covers what each one actually offers, where each one is thinner than it looks, and a quick quiz if you would rather skip the reading.
What Actually Separates These Three
Every broker on this list solves the same basic problem: one account, many books, one settlement layer. Where they differ is depth and specialization, and that is the part most "best broker" roundups skip in favor of a decimal score that does not mean much. BetInAsia's Asian handicap depth is the strongest of the three, not close, and it is paired with prediction-market reach (Polymarket and Kalshi markets and odds surfaced inside BetInAsia's own betslip, not a direct login to either platform) that neither competitor matches. MadMarket's exchange access is a genuine second option, strong on Betfair, Matchbook and its own Sharp Exchange, but it thins out fast once you are outside a handful of major exchanges. Sportmarket does not try to compete on either front. It wins on simplicity: no commission, a wide bookmaker spread, and an account structure that does not require a learning curve before your first bet.
BetInAsia (BLACK): Best for Asian Handicap Depth and Prediction-Market Reach
BLACK is BetInAsia's brokerage product, built around Asian handicap and totals markets sourced from sharp Asian bookmakers, the same pricing depth professional bettors chase because the lines move faster and land closer to true probability than a recreational sportsbook's. Inside the same account, BLACK also surfaces Polymarket's and Kalshi's markets and odds through its own betslip; you are trading against BetInAsia's book, not connecting a wallet to Polymarket's contracts directly, which is exactly why the access works from places where Polymarket itself does not.
Under the hood, BLACK's Asian-bookmaker layer runs through Sbobet, 3et, Turf7, SharpBet and Singbet, plus Pinnacle priced through its own PS3838 feed, the same route professional Pinnacle bettors use when their home country blocks direct signup. On the exchange side it adds Betfair, Betdaq, Matchbook, Mollybet, Smarkets and Orbit Exchange, all run through BetInAsia's own Sharp Exchange pricing rather than a dozen separate exchange logins.
Payment methods run the usual spread for a brokerage aimed at a global client base: bank transfer, major cards, and crypto funding for clients who prefer it, though it is not built crypto-first the way MadMarket is. The standout tool is the unified betslip itself, pricing the same bet across multiple linked books to shop the best line without opening five separate tabs.
Concrete scenario: you are pricing an Asian handicap on a mid-table J-League match a European sportsbook barely bothers to list. BLACK's depth is exactly where it separates itself; the market exists, and it is priced properly. The honest caveat: if your interest is purely European exchange trading, in-play Betfair-style scalping, BLACK is not the sharpest tool on this list for that specific job. That is MadMarket.
MadMarket (Edge): Best for Exchange Access and Crypto-First Funding
Edge, MadMarket's brokerage layer, is built for people who already think in exchange terms: back and lay, matched betting, chasing the tightest spread rather than a fixed price. It aggregates Betfair, Betdaq, Matchbook, Mollybet, Smarkets and Orbit Exchange, all priced through MadMarket's own Sharp Exchange engine, and it covers the same Asian-bookmaker spread as BLACK (Sbobet, 3et, Turf7, SharpBet, Singbet, plus Pinnacle through its own Probet42 feed), alongside Polymarket and Kalshi markets folded into the same interface (again, priced and settled through MadMarket's own engine, not a direct line to either platform).
Funding is where Edge actually differentiates itself: it is built crypto-first, with fast deposits and withdrawals in the major coins, which matters if you are moving size and do not want a card processor holding funds for three business days. Card and bank options exist too; they are just not the point of the product.
Concrete scenario: you want to lay a heavy favorite pre-match on Betfair, then hedge the same position on Matchbook a few minutes later once the price drifts. Edge's combined order view makes that a single workflow instead of two logged-in tabs and a stopwatch. Honest caveat: outside the three or four exchanges it covers well, and outside major crypto rails, Edge's bookmaker-side spread is noticeably thinner than either BetInAsia's or Sportmarket's. It is a specialist tool, not an everything-account.
Sportmarket (Pro): Best for Straightforward, No-Commission Pricing
Pro is the least specialized of the three, and that is the point. No commission on settled bets, real-time pricing pulled across more than fifteen bookmakers, and an account setup that does not ask a first-time broker user to learn exchange terminology before placing a bet.
Named out, Pro's own bookmaker list runs through Sbobet, 3et and SharpBet directly, Pinnacle through its own PS3838 access, and Singbet on request. On the exchange side, Pro covers Betfair and Orbit Exchange through its own FairExchange feed, plus Betdaq, Matchbook, Mollybet, Smarkets, and yes, Polymarket. What it does not carry is Kalshi. If election-market access specifically is the point of opening an account, that is a real reason to look at BetInAsia or MadMarket instead, not a minor footnote.
Payment methods lean traditional: cards and bank transfer are the default rails, with fewer crypto options than MadMarket offers. The standout feature is the price-comparison view itself, the same match laid out across every linked book, so you can see the gap between the best and worst price before you click anything.
Concrete scenario: you bet mainstream markets on the biggest leagues most weekends and have never needed an exchange account. Pro gets you a meaningfully better price than a single sportsbook without asking you to change how you bet. Honest caveat: it does not carry BLACK's Asian handicap depth or Edge's exchange access, so if either of those is genuinely what you need, Pro is the wrong pick. Not because it is worse. Because it is a different tool.
How We Ranked These
The order here (BetInAsia, then MadMarket, then Sportmarket) reflects depth and breadth of market access first: how many bookmakers and exchanges sit behind the account, how deep the coverage goes in markets that are hardest to get a fair price on elsewhere, and how cleanly Polymarket's and Kalshi's markets are folded into the same betslip rather than bolted on as an afterthought. Payment flexibility and account complexity come second. None of the three gets a score out of ten here; a decimal next to a broker's name always looks more precise than the underlying judgment actually is, and it hides the fact that "best" depends heavily on what you bet and how you bet it. If you are still working out what a broker actually does mechanically before comparing any of them, start here first, it will make the rest of this page click faster.
Which Broker Fits You?
Four quick questions, no email required. Answer honestly about how you actually bet, not how you wish you bet, and the quiz below will point at the account most likely to fit.
None of this replaces doing your own diligence. Account minimums, regional availability and your own bet mix all matter more than any ranking on this page. If you want a slower walk through the actual decision criteria before opening an account, how to choose a broker covers that in more depth. For most people reading this page, though, the honest answer is one of the three above, and which one comes down to what you are actually trying to do with it.
