fomo adds cross margin to its perps and opens an Anthropic pre-IPO market with up to 10x leverage

Cross margin arrives

fomo announced on its official X account on 26 October 2026 at 21:55 UTC that cross margin is now live on fomo perps. In fomo's words, traders can manage multiple positions from one shared balance instead of keeping collateral separate for every trade.

In general terms, isolated margin ring-fences the collateral behind each position, while cross margin pools it. A shared balance can keep a position open longer because spare funds back it, but it also means a loss on one trade can eat into the collateral supporting the others. That is our explanation; fomo's post does not set out its liquidation rules or whether isolated margin remains the default.

fomo framed the change as part of a wider push, saying the perps experience is expanding, from better tools to better discovery. The short launch video repeats the idea with the words cross margin perps and available collateral.

An Anthropic market before any IPO

Earlier the same day, at 18:29 UTC, fomo said a pre-IPO perp market for Anthropic is now live on the app. The ticker is ANT and fomo allows up to 10x leverage. The attached artwork simply reads ANT 10x, live on fomo.

A pre-IPO perp is a contract that tracks a price for a company that is not yet listed on a stock exchange. It does not give you Anthropic shares. fomo's post does not describe how the ANT price is formed, so check the market details in the app before trading.

Who can use it

fomo attached the same restriction to both announcements in follow-up posts: not available in the U.S. or to U.S. persons. Neither post lists other excluded countries or mentions fee changes.

Our take

Cross margin is a practical upgrade for traders running several fomo positions at once, but pooled collateral cuts both ways. Combined with 10x leverage on a thinly understood pre-IPO market like ANT, small position sizes are the sensible way to start.
