Yes — for liquidity, Betfair is still the best exchange in 2026 and it isn't close, especially in UK/Irish racing and football. But "best" depends on you: Smarkets and some Betdaq markets undercut it on commission. If depth and fast fills matter, Betfair wins; if your markets are liquid enough elsewhere, lower fees can win.
This is a cluster sub of our pillar, Betfair vs competitors. The pillar lines up every platform; this page answers the single question readers actually type — is the market leader still worth its commission — and gives a verdict rather than a fence-sit.
The verdict, up front
Betfair is still the best all-round exchange in 2026, and the gap is almost entirely about liquidity. No rival has come close to matching its matched volumes in the markets that matter most to UK, Irish and Australian traders. That depth is worth more to a working trader than a percentage point of commission — because you can't trade money that isn't there.
But "best for everyone" is a lazy claim, and I won't make it. If you trade markets where liquidity is adequate everywhere, Smarkets' lower commission is a genuine, recurring saving. The right answer is conditional, and the rest of this page is the conditions.
Liquidity: where Betfair is untouchable
This is the whole ballgame, so let's be concrete. On a Saturday afternoon of UK racing, a single major-meeting win market on Betfair will match seven figures; the equivalent market on Smarkets or Betdaq often matches a fraction of that. In Premier League football in-play, Betfair turns over tens of millions per match while rivals are an order of magnitude smaller.
For a trader, deeper liquidity means three tangible things: tighter spreads (the gap between back and lay is smaller), bigger money available at each price (you can get a real stake matched without moving the market), and faster fills (your bet matches instantly instead of sitting). For scalping in particular — see scalping — this is decisive. A two-tick scalp on a thin exchange dies on slippage. The mechanics of why depth matters are in how the exchange works and how to read a market.
| Factor | Betfair | Smarkets | Betdaq |
|---|---|---|---|
| UK/IE racing liquidity | Deepest by far | Moderate | Moderate/low |
| Football in-play depth | Deepest | Lower | Lower |
| Headline commission | 2% base (UK) | ~2% but often lower effective | Often lower / promotions |
| Premium Charge | Yes (small minority) | No | No |
| Software/API ecosystem | Largest | Good | Good |
Commission: where rivals win
Here's where I'll give the rivals their due. Smarkets has built its whole pitch on a flat, lower commission and no Premium Charge, and for many traders that's a real, repeatable edge over a year of activity. Betdaq has historically run lower rates and promotions too. On a like-for-like winning market, you keep more of your profit on those platforms than on Betfair's 2% base.
The catch is that commission is only one side of the ledger. If a lower-commission exchange gives you worse fills because the liquidity isn't there, the slippage can quietly cost more than the commission saving. I've watched traders "save" on commission and lose more to bad fills than they ever saved on fees. Run your own numbers in the calculator, and read the detailed cost breakdown in Betfair vs Smarkets commission compared and our full Smarkets comparison.
The Premium Charge question
The Premium Charge is the most-cited reason to leave Betfair — and it's relevant to far fewer people than the internet suggests. It applies only to a small set of accounts that win consistently and heavily relative to their commission paid. If you're a part-time trader making modest profits, you will almost certainly never meet it, and using it as a reason to avoid Betfair is letting a rare edge case drive a common decision.
If you are a high-volume, consistently large winner, then the maths genuinely changes and a lower-commission exchange deserves serious thought. But even then, weigh the fee saving against the worse fills on thinner markets — it's not automatically a win. The full mechanics are in our Premium Charge guide.
To put numbers on the liquidity-vs-commission trade-off, I ran the same pre-off racing scalp across two exchanges on the same Saturday card in May 2026.
Betfair: backed £300 on the favourite at 2.50, filled instantly. Laid back at 2.46 as it shortened, full stake matched. Green-up ~£4.90; after 2% commission, net ~£4.80.
Thinner rival, lower commission: tried the identical £300 back at 2.50 — only £180 matched at the price, the rest filled a tick worse at 2.52. The exit was similarly draggy. Despite paying less commission, the worse fills left me with ~£3.60 net.
The point: the rival's lower fee was real, but it didn't cover the slippage from missing liquidity. On a deep market, Betfair's depth out-earned the cheaper exchange even after its higher commission. On a market where both had ample liquidity, the cheaper exchange would have won. That's the entire decision in one trade.
Tools, API and ecosystem
Betfair's longevity has built the deepest software ecosystem of any exchange. Bet Angel and Geeks Toy were built around it, the Betfair API is mature and well-documented, and almost every automation tool supports it first. Rivals are supported by good software too, but if you want the widest choice of ladders, bots and automation, Betfair remains the default. See the full picture in best Betfair trading software 2026.
Who should actually switch
Cutting through the tribalism, here's who genuinely benefits from looking past Betfair:
- Consistent high-volume winners who realistically face the Premium Charge — the commission saving compounds.
- Traders whose markets are liquid everywhere — if your niche has adequate depth on Smarkets, the lower fee is free money.
- Value bettors, not scalpers — if you're taking a price and holding, fast fills matter less, so commission dominates.
And who should stay: anyone who scalps, anyone trading UK/Irish racing or football in-play, and anyone whose stakes are large enough that slippage on a thin market would hurt. For the wider field beyond the big three, see best alternatives and Betfair vs Matchbook.
No exchange makes you a winning trader. Most people lose money on betting exchanges regardless of which one they use, and chasing a lower commission rarely turns a losing strategy into a winning one. Choose the exchange that fits your markets, but understand the edge has to come from your trading, not your fee rate. Past results don't guarantee future returns.
The multi-exchange answer
The honest pro move is to stop treating this as either/or. Holding accounts on Betfair, Smarkets and Betdaq costs nothing, and serious traders route each trade to wherever it's best: Betfair when liquidity is critical, the cheaper exchange when fees dominate and depth is adequate. That's the answer I actually use, and it makes "which is best" the wrong question — the right question is "best for this trade."
For most traders, Betfair's liquidity still justifies its commission. Open an account, but keep a cheaper exchange in your back pocket for the markets where fees matter more than depth.

Part of why this question keeps coming up is that the exchange landscape genuinely has shifted. When I started in 2007, Betfair was effectively the only liquid exchange in town — Betdaq existed but trailed badly, and Smarkets didn't exist yet. "Which exchange" wasn't a real question; there was one.
Three things changed that. Smarkets arrived with a deliberately low, flat commission and modern interface, giving cost-focused traders a credible alternative. The Premium Charge — introduced and later increased — gave Betfair's biggest winners a concrete financial reason to look elsewhere. And the maturing of trading software meant rivals could be supported by good ladders and bots rather than only Betfair. None of that dethroned Betfair on liquidity, but it ended the era where Betfair was the automatic, unexamined default. The history is worth knowing because it explains why the honest answer in 2026 is "it depends" rather than the flat "Betfair, obviously" that was true fifteen years ago.
Best exchange by what you actually do
Rather than a single ranking, it's more useful to match the exchange to the activity:
- Pre-off racing scalping: Betfair. Tight spreads and instant fills on deep UK/Irish markets are non-negotiable for tick-by-tick work. See scalping.
- Football in-play / lay the draw: Betfair. The in-play depth simply isn't replicated elsewhere — see lay the draw and in-play trading.
- Value betting and holding positions: Smarkets or Betdaq can win, because fast fills matter less when you're taking a price and waiting, so commission dominates.
- High-volume professional winning: seriously model the Premium Charge — this is where leaving Betfair can pay, per the Premium Charge guide.
- Matched betting: liquidity for laying matters, so Betfair is usually the safer default for getting lays matched at fair prices — see advanced matched betting.

FAQ
Is Betfair still the best exchange in 2026? For liquidity, yes — clearly. For commission alone, Smarkets and some Betdaq markets undercut it. Best depends on whether you value depth or low cost.
Does Betfair have more liquidity than Smarkets? Yes, substantially, especially in mainstream racing and football. That depth often outweighs Smarkets' lower commission for traders.
Is the Premium Charge a reason to leave? Only for a small number of consistently large winners. Most traders never trigger it.
Should I use more than one exchange? Many serious traders do — Betfair for liquidity-critical trades, a cheaper exchange where fees dominate. Holding all three costs nothing.
Will a cheaper exchange make me more money? Not by itself. Lower fees don't fix a losing strategy, and worse fills can cost more than the fee saving.
Which is best for scalping? Betfair, because scalping lives and dies on tight spreads and fast fills, which require deep liquidity.
