Se Yong Park: Why The Trillion Dollar Opportunity Is Social (Ground Floor)

Se Yong Park’s ambition is for FOMO to become finance’s social graph: a place where people can discover and discuss on-chain assets, major cryptocurrencies, perps, prediction markets, stocks, IWA’s, and yield. He wants users to move beyond meme trading toward tokenized equities and yield, arguing that an industry that fails to make that transition would be unsustainable and that the narrower experience would not hold his interest. He expects tokenized-equity volume to move increasingly on-chain within 6–12 months, making stocks a materially larger share of on-chain market volume, as part of a longer shift toward everything moving on-chain.

FOMO had about 2.5 million lifetime users, though Park estimated that roughly 600,000 might use the app today; he said about 75% visit in a given month. The product had been live for around a year and a half. Retention fell in months four through six and then rose in months seven through nine, a pattern Park said depends partly on market tailwinds. He sees education, additional asset classes, and users teaching one another through a tailored social graph as ways to help address churn and make returning users more effective, rather than assuming that initial adoption alone will sustain engagement.

A central product gap is the lack of substantive conversation: users can view, like, and share thesis posts, but cannot yet have meaningful two-way discussions with leading traders and educators. Park believes investing is learned by doing, even when early attempts are painful. Moving users from lottery-style trades and quick wins toward portfolios held for weeks or months is difficult, particularly for people accustomed to sports gambling or similarly fast outcomes. Education and conversation could support that change, but Park’s account makes clear that product features cannot remove the difficulty of changing users’ habits.

Park says FOMO does not own its launchpad, AMM, or other trading layers, so it has less reason to optimize for trading volume or user losses and more reason to focus on users’ longevity. He sees a better product as the best way to retain people when they return. The platform also rewards contributions to its social graph, including onboarding users, writing educational content, and discovering things early. Crater Awards paid out about $11 million in three weeks, alongside another $6 million in referrals. Park favors smaller rewards across the user journey rather than depending only on a large prize at the end.

Park draws on Facebook’s evolution from a relationship-centered social graph to a content-centered interest graph, and expects AI to make content easier to produce as a third era of social media emerges. FOMO’s market-based feedback, he argues, can be more objective than likes: users can see whether a post or discovery succeeded through market-cap movement and potential gains. He anticipates a “speculation graph” that captures activity by agents as well as people. In that setting, P&L and risk-reward could provide measures of performance, though they do not remove the need for public traders to follow their own rules and avoid harming others.

For highly visible traders, Park advises protecting their reputations and helping others rather than trying to account for every opinion. He welcomes competition and new experiments, calling Arc an exciting chain to launch on. He is particularly interested in how AI commerce and the agentic economy develop on Arc, which he describes as institutionally focused.
