Wall Street Interns Drive Prediction Market Adoption as Platforms Gain Financial Mainstream

Prediction markets have moved decisively into the mainstream financial consciousness, with data from Morgan Stanley's annual survey of summer interns offering a fresh window into how the next generation of finance professionals engages with event-contract trading platforms.

The investment bank's poll of more than 500 North American summer interns, many aged 21 or younger, found that over a quarter have used a betting or prediction market mobile application within the past 12 months. Among those users, 55% employ multiple prediction market apps, with the market leaders capturing the strongest adoption. The survey marks the first year Morgan Stanley has included questions about prediction market and betting usage in its intern polling, reflecting the category's maturation within financial services.

The headline figures suggest prediction markets have achieved what many emerging financial products struggle to obtain: normalization among aspirational professionals. Yet context matters. Data from the National Council on Problem Gambling indicates that 37% of Americans aged 18 to 34 have used a prediction market, meaning Morgan Stanley interns are adopting at rates slightly below their broader age cohort. This suggests that finance-focused young people engage with prediction markets at levels consistent with generational trends rather than at dramatically elevated rates.

However, the survey's timing arrives as major financial institutions have begun implementing formal guardrails around employee participation in prediction markets. Both Goldman Sachs and Morgan Stanley have recently restricted staff trading in event contracts, with Goldman prohibiting trading on financial and political event contracts entirely. Morgan Stanley updated its employee code of conduct to explicitly address prediction market participation. These policy moves signal that while adoption grows, institutional risk and compliance teams view unstructured participation as problematic.

An important regulatory tension runs beneath the surface of adoption data. The National Council on Problem Gambling has flagged that some prediction market platforms maintain 18+ age requirements, whereas sports betting maintains a federal 21+ standard. This discrepancy troubles regulators monitoring young adult gambling behavior. Notably, Novig, an operator of a sports-only peer-to-peer exchange, recently became one of the first event contract platforms to implement a 21+ age floor, suggesting industry self-regulation may be tightening.

Morgan Stanley's research also tested a foundational assumption underlying prediction market legitimacy: the 'wisdom of the crowd.' The bank's analysis found that the case for prediction market superiority over traditional polling is not clear-cut. While markets generate signals from collective participation, sophisticated polling adjustments and aggregation methods can match or exceed prediction market accuracy in key domains. 'Superforecasters' working in aggregated teams consistently outperform prediction markets on forecast accuracy, introducing a note of skepticism about whether decentralized markets always capture superior information.

The intern survey captures a market inflection point. Prediction markets have achieved sufficient cultural penetration that a major investment bank now tracks their usage alongside traditional financial instruments. Yet institutional responses reveal ongoing concern about systemic and individual risk. As prediction markets continue growing in trading volume and user engagement, the tension between mainstream adoption and institutional caution will likely define the next phase of regulatory development.
