Fomo's $75M Series B: What the SEC/CFTC Non-Custodial Ruling Means for Traders

Two things happened close together in early-to-mid 2026 that are worth understanding as one story, not two separate headlines: a regulatory clarification, and a large funding round that followed it.

What the SEC and CFTC actually said

In March 2026, the SEC and CFTC jointly issued guidance addressing a question that had been sitting unresolved for years: do non-custodial wallet interfaces — apps like Fomo, where the platform never takes custody of user funds — need to register as broker-dealers the way traditional trading platforms do?

The answer, in the form of a new exemption category called “Covered User Interface Provider,” was no — provided the platform genuinely doesn’t take custody. This gave a legal green light to a model that non-custodial consumer trading apps had, as one analyst put it, been “navigating around for years” without explicit regulatory backing.

Then came the funding

Shortly after, Index Ventures led a $75 million Series B round into Fomo at a $550 million valuation, with Union Square Ventures and Benchmark also participating — bringing Fomo’s total disclosed funding to roughly $94 million. The timing isn’t a coincidence. Generalist venture capital tends to be cautious about products operating in unresolved regulatory territory; a round of this size, from investors of this profile, landing right after legal clarity arrived is a fairly direct signal of what that clarity unlocked.

Why this matters if you’re actually using the app

A few practical implications for traders, beyond the headline numbers:

Legitimacy. This isn’t a question of “is this app going to disappear next month” in the way it might be reasonable to wonder about a newer, unfunded, unregulated product. Real institutional capital and real regulatory clarity both point the same direction.

What it doesn’t change. The funding and the ruling are about the platform’s legal structure and business viability — they don’t change what you can trade or what it costs. Spot trading fees are still roughly 0.5% per trade, perpetuals (via Hyperliquid, unavailable to US users) still carry their own fee structure, and the underlying risks of trading volatile assets are exactly what they were before any of this happened.

Geographic asymmetry remains. Even with the SEC/CFTC clarity, US users still can’t access perpetuals on Fomo — that’s a separate regulatory gap (derivatives registration, not the non-custodial question) that this particular guidance didn’t resolve.

The bigger picture

This is arguably more significant for the non-custodial trading category generally than for Fomo specifically — a real regulatory pathway for apps that never take custody of user funds is a meaningful shift, and Fomo happens to be the highest-profile example benefiting from it right now. Worth watching whether other platforms in the category see similar funding momentum follow the same pattern.
