Can You Actually Trade Size at 100x? Stock Futures Leverage Tiers and Position Limits Explained
Exchanges put big leverage numbers on their banners.
What the banner does not tell you is how much you can actually hold at that number.
On MEXC stock futures, that answer lives in a tier table, and 100x sits in the smallest tier.
This guide reads the live tables for three named contracts and shows what an independent report found at 100x.
Key Takeaways
- On MEXC stock futures, the leverage you select sets the largest position you can open, and that cap shrinks as leverage rises.
- As of September 22, 2026, SNDK's top tier caps a position at 80,000 contracts (80 shares' worth) at any leverage above 50x, up to the contract's 200x ceiling, with a 0.4% maintenance margin rate.
- TokenInsight's August 2026 report found MEXC was the only sampled venue that consistently supported meaningful position sizes at 100x as of July 29, 2026, though not the largest cap at every tier.
- Maximum leverage is set per contract: SNDK, MU and SK hynix stock futures showed a 200x ceiling on September 22, 2026, and MEXC can lower it in volatile markets.
- SOXL draws tighter limits at several sampled venues, which TokenInsight links to the fund's own 3x leverage stacking under futures leverage.
- In the worked example, 10,000 USDT at 20x survives a 4% drop, while the largest 100x position on the same contract is liquidated after a 0.6% drop, before fees and funding.
What Is a Position Limit in Futures, and Why Do Leverage Tiers Shrink It?
A position limit is the largest position, in contracts or USDT, that MEXC lets you open at the leverage you selected on a given stock future.
Limits come in tiers.
The higher the leverage, the smaller the cap, and the bigger the position, the higher the maintenance margin rate it needs to stay open.
MEXC runs a tiered margin model, explained in its guide to risk limits on MEXC futures.
Each tier carries three numbers: a maximum position size, the highest leverage allowed at that size, and a maintenance margin rate.
Your maintenance margin rate follows your position size, not the leverage you chose, so a large position at 10x can carry a higher rate than a small one at 100x.
If margin itself is new to you, start with leverage in futures trading.
How much can you hold at 100x on a MEXC stock future?
As of September 22, 2026, MEXC's contract data caps the top tier at 80,000 contracts on SNDK, 20,000 on MU and 75,000 on SK hynix stock futures, and that top tier covers every leverage setting above 50x, including 100x.
Lower tiers allow larger positions at lower leverage, each with its own maintenance margin rate.
The tiers below come from MEXC's public futures contract API on September 22, 2026; the risk-limit page for SNDK shows the same tiers in USDT at the live price, which is why the dollar figure there moves with the stock even when the tier has not changed.
Contract | Tier | Max position (contracts) | Shares' worth | Max leverage | Maintenance margin rate |
SNDK | 1 | 80,000 | 80 | 200x | 0.40% |
SNDK | 2 | 600,000 | 600 | 50x | 1% |
SNDK | 3 | 4,500,000 | 4,500 | 20x | 2% |
SNDK | 4 | 11,600,000 | 11,600 | 10x | 5% |
MU | 1 | 20,000 | 200 | 200x | 0.40% |
MU | 2 | 100,000 | 1,000 | 50x | 1% |
MU | 3 | 250,000 | 2,500 | 20x | 2% |
MU | 4 | 1,000,000 | 10,000 | 10x | 5% |
SK hynix | 1 | 75,000 | 75 | 200x | 0.40% |
SK hynix | 2 | 145,000 | 145 | 50x | 1% |
SK hynix | 3 | 1,250,000 | 1,250 | 20x | 2% |
SK hynix | 4 | 5,000,000 | 5,000 | 10x | 5% |
On all three contracts, 100x and 200x share the top tier, so choosing 200x does not shrink the cap any further.

What did TokenInsight find about 100x position capacity?
TokenInsight's Equity Perpetuals Market Report, published August 26, 2026, found that position limits tighten as leverage rises at all five centralized exchanges in its sample, and that MEXC was the only one to consistently support meaningful position sizes at 100x across the five stock futures checked, as of July 29, 2026.
In that snapshot, MEXC's 100x caps ran from 46,598 USDT on INTC to 97,767 USDT on SK hynix, with SPCX at 73,787 USDT, SNDK at 63,623 USDT and SOXL at 55,366 USDT, all at July prices.
MEXC did not post the largest limit at every tier: on SPCX, one of the other sampled venues published a larger cap at 10x, 20x and 50x.
Where MEXC separates is at 100x, the only tier at which it was the only venue in the sample with a published cap on all five contracts, and on the other four contracts its caps were the largest in the sample at every tier.
What is the maximum leverage on MEXC stock futures?
Maximum leverage on MEXC stock futures is set contract by contract and shown on each trading page.
As of September 22, 2026, MEXC's contract data listed a 200x maximum on SNDK, MU and SK hynix stock futures, and MEXC's July 2026 stock futures announcement describes leverage of up to 200x.
Maximum leverage and position limit are different numbers: one sets the margin you post per dollar of exposure, the other caps how many dollars you can hold.
The ceiling can move, since MEXC's risk-limit rules allow maximum leverage to be lowered in volatile markets, and positions above a lowered ceiling can then be closed but not increased.
So trust the number on the MEXC stock futures trading page on the day you trade.
How is leverage on MEXC stock futures different from margin on traditional stock futures?
MEXC stock futures are perpetual contracts margined in USDT or USDC: they have no expiry date, although MEXC can settle a contract early around corporate events, and you choose the leverage yourself, up to the contract's ceiling.
Traditional stock futures carry a fixed expiry, an initial margin set by the exchange and often topped up by the broker, and no leverage dial, so your leverage is whatever that margin implies.
On MEXC, the margin percentage follows from the leverage you pick, and the tier you land in sets the cap.
If you come from index futures, treat the leverage slider as a margin setting and the tier table as the size setting.
Why does SOXL get tighter limits?
SOXL draws tighter limits at several venues in TokenInsight's sample, and the report links that to the fund's own leverage.
It is a 3x leveraged ETF built to deliver three times the daily move of a semiconductor index, so a futures position on SOXL stacks exchange leverage on top of the fund's own leverage.
The effective exposure to the sector is the product of the two.
TokenInsight's report treats SOXL as a special case for this reason and notes that several sampled venues set tighter SOXL limits than on ordinary single stocks.
MEXC still listed a 100x tier on SOXL in that snapshot, at the 55,366 USDT shown above.
How do you pick a tier without getting liquidated?
Pick the tier by the size you actually want to hold, not by the leverage you would like to use.
The cap decides which leverage settings are available for that size, and the tier's maintenance margin rate sets how far price can move against you before liquidation.
Worked example: 10,000 USDT on SNDK at 20x versus 100x
Assume SNDK trades at 800 USDT, a round number, not a quote.
At 20x, 10,000 USDT of margin opens 10,000 × 20 = 200,000 USDT of exposure, which is 200,000 ÷ 800 = 250 shares, or 250,000 contracts.
That size sits in tier 2, so the maintenance margin rate is 1%: 200,000 × 1% = 2,000 USDT.
MEXC's long liquidation formula, maintenance margin minus position margin plus exposure, divided by shares, gives (2,000 - 10,000 + 200,000) ÷ 250 = 768 USDT, a 4% drop.
At 100x, the SNDK cap is 80 shares, or 80 × 800 = 64,000 USDT, so 10,000 USDT cannot be deployed at all.
That position needs 64,000 ÷ 100 = 640 USDT of margin, and tier 1's maintenance margin is 64,000 × 0.4% = 256 USDT.
Liquidation sits at (256 - 640 + 64,000) ÷ 80 = 795.2 USDT, a 0.6% drop.
Both prices exclude liquidation fees and funding, which move the real trigger a little closer to entry.
If losses hit a large position, MEXC's laddered liquidation steps it down a tier before closing the rest.
If the insurance fund cannot cover a shortfall, auto-deleveraging can close profitable traders on the other side, which is why the futures trading risks page is required reading.
MEXC CEO Vugar Usi told Finance Magnates in August 2026 that he "struggle[s] to construct a retail case" for 500x leverage on forex and gold; the math above is our own reason for treating 100x as no retail default either.
FAQ
What is the maximum leverage on stock futures?
It is set per contract; SNDK, MU and SK hynix stock futures showed a 200x maximum on September 22, 2026, and each trading page shows its own ceiling.
Why can't I open a bigger position at 100x?
Because 100x sits in the top tier with the smallest cap; lowering leverage moves you to a tier with a larger cap and more margin per dollar.
What is a risk limit tier?
A band of position sizes sharing one maximum leverage and one maintenance margin rate, published per contract on MEXC's risk-limit page.
What is maintenance margin?
The minimum margin a position must keep to stay open: position value times the tier's maintenance margin rate.
Does the position limit change with the market?
Yes; tiers are set in contracts, so the USDT cap moves with the share price, and MEXC can adjust tiers, leverage and margin rates in volatile markets.
Is 100x available on every stock future?
Not necessarily; maximum leverage is set contract by contract and can change, so the trading page is the only reliable answer.
What happens if I exceed a tier?
An order above the cap will not open at that leverage until you lower it, and if MEXC tightens a limit after you are in, you can close but not add.
Conclusion
The leverage number on the banner is a margin setting.
The tier table is the size setting, and it decides what you can actually do at 100x.
Read it for the contract you trade, note the date, and size the position before you touch the slider.
The live tiers are one click from any MEXC stock futures trading page.
