Fomo Perpetuals Explained: Fees, Access & How They Actually Work

Fomo added perpetual futures on top of its original spot trading product, and the way it’s built is worth understanding before you trade — it’s not a self-contained feature, it’s a layer on top of another platform entirely.

Perpetuals run through Hyperliquid, not Fomo itself

When you open a perp position on Fomo, you’re trading on Hyperliquid’s infrastructure through Fomo’s interface. Fomo adds its own front-end — the social feed, the simplified UI, the fee handling — on top of Hyperliquid’s actual order execution. That’s a meaningful distinction: the liquidity, price execution, and underlying mechanics come from Hyperliquid; Fomo is the layer you interact with.

What it costs

Fomo charges roughly 0.05% per side on top of whatever Hyperliquid’s own underlying fees are for that trade. In practice, this roughly doubles the direct cost of a perpetual trade compared to going through Hyperliquid directly — you’re paying for the convenience and interface, not just the trade itself. Compare that to spot trading on Fomo, which runs about 0.5% per trade with no secondary venue fee stacked on top. See our full fees breakdown for the numbers side by side.

Why US users can’t trade perpetuals on Fomo

This is the detail people miss most often: perpetual futures are not currently available to US-based users on Fomo. It’s not a Fomo product restriction so much as a regulatory one — offering leveraged derivatives products in the US requires domestic registrations that Fomo hasn’t obtained, even though its core non-custodial spot trading operates legally nationwide following the SEC/CFTC’s March 2026 guidance on non-custodial wallet interfaces. If you’re US-based, spot trading (memecoins, altcoins, stablecoins) is what’s available to you on Fomo; perpetuals aren’t, regardless of what you might see referenced elsewhere.

What this means in practice

If you’re outside the US and considering perps on Fomo, treat it as trading on Hyperliquid with an extra fee layer and a friendlier interface — which may or may not be worth it depending on how much you value the UI versus the extra cost. If you’re a frequent or larger-size trader, that 0.05%-per-side markup adds up fast and is worth running the numbers on before committing to Fomo as your primary venue for perps specifically (as opposed to spot, where its own fee structure stands on its own).

Leveraged perpetuals are also simply a higher-risk product category than spot trading, independent of which platform you use — position sizing and understanding liquidation mechanics matter more here than almost anywhere else in crypto trading. That’s true on any venue, not a Fomo-specific caveat, but worth repeating given how frictionless the app makes it to open a position.
