When margin stops being the limit
Unlimited leverage
None of the nine brokers we track offers unlimited leverage; the highest published figure on our list is 1:3000 at Alpari, and RoboForex's «up to 1:2000» is a marketing page rather than an uncapped account. Where the product does exist, it removes the margin requirement — which means the stop-out level becomes the only thing standing between a small account and zero.
Checked against each broker's own pages
What «unlimited» actually removes
Ordinary leverage sets how much margin a position requires: at 1:30 a $1,000 position needs about $33, at 1:3000 about 30 cents. Unlimited leverage sets that requirement to zero — the position needs no margin at all, so nothing in the account balance limits the size you can open.
It is almost always bounded in ways the headline omits. Brokers offering it typically restrict it to accounts below a balance threshold, to certain instruments, and to normal market hours, reverting to ordinary leverage outside those conditions. The restriction exists because the broker's own risk is what is being managed, not yours.
With margin out of the picture, one mechanism remains: the stop-out. The broker closes positions when equity falls below a set percentage — and on a position opened with no margin requirement, that threshold arrives after a movement measured in fractions of a pip.
The arithmetic that makes the term dangerous
Take $100 and no margin requirement. Nothing prevents opening a position of ten standard lots, where one pip on EUR/USD is worth $100. The first pip against you takes the account. At three lots — the size 1:3000 permits on that balance — it takes three and a half pips.
This is the same mechanism as high leverage, taken to its limit, and it is why regulators cap the number rather than the marketing. The FCA's rules put retail leverage between 30:1 and 2:1 with a mandatory close-out at 50% of required margin; ASIC did the same and reported quarterly retail losses falling from $372 million to $22 million. Neither regime permits a product where margin is zero.
So an account with unlimited leverage is, by construction, an account outside those regimes — which answers the second half of the question in the title. What you pay for it is the compensation scheme, the leverage cap and the negative balance guarantee that came with them.
Who offers it, and who does not
Not the brokers on this site. We checked all nine on 24 August 2026: the highest published leverage is 1:3000 on Alpari's ECN accounts, then 1:2000 at RoboForex, 1:1000 at LiteFinance, 1:800 on Deriv's gold, 500:1 at Bybit and 1:500 at FxPro. None publishes an account without a margin requirement.
The product does exist elsewhere, marketed by offshore entities of brokers outside our list, and the search results for it are otherwise made up of content farms recycling the same page. That is a reasonable summary of the category: a genuine but narrow product, surrounded by pages written to rank rather than to inform.
If the appeal is opening a position larger than your balance would normally allow, the honest reframing is that you are not being given more capital — you are being allowed to lose the capital you have faster.
The question to ask instead
What margin does the position I intend to open actually require? A 0.01-lot trade on EUR/USD is about $1,000 of exposure, needing roughly $33 at 1:30 and cents at 1:3000. If your intended size fits inside a regulated account's cap, unlimited leverage offers you nothing but the ability to exceed it.
And what is the stop-out level? On any highly leveraged account that number decides the outcome, and it is published in the account specification rather than in the marketing — Alpari, for instance, publishes 20% on its Micro and Standard accounts and 50% on its ECN ones.
Questions people ask
Which brokers offer unlimited leverage?
None of the nine we track. The highest published figures on our list are 1:3000 at Alpari, 1:2000 at RoboForex and 1:1000 at LiteFinance. The product exists at some offshore brokers outside this list, usually restricted to small balances, selected instruments and normal market hours.
What does unlimited leverage mean?
That a position requires no margin at all, so the account balance no longer limits position size. The only remaining constraint is the stop-out level at which the broker closes your positions — which, on a position opened with no margin, arrives within a fraction of a pip.
Is unlimited leverage legal?
Not for retail clients in the UK, the EU or Australia, where leverage is capped between 30:1 and 2:1 with mandatory close-out at 50% of required margin. Accounts offering it sit with entities in jurisdictions without those rules — and therefore without their compensation schemes.
What happens to a $100 account on unlimited leverage?
It can open a position where one pip is worth more than the balance. Ten standard lots on EUR/USD move $100 per pip; the first pip against you ends the account. That is not an edge case — it is the arithmetic the product creates.
Is high leverage the same thing?
It is the same mechanism with a limit still attached. 1:3000 leaves a $100 account about three and a half pips of room; unlimited leverage removes even that boundary and leaves only the stop-out.
What each broker does publish, entity by entity, is on high leverage brokers, and the protections that come with a capped account are on regulated forex brokers.
