Polymarket Hires Goldman Sachs Veteran to Court Institutional Traders
The hire signals a strategic shift by the prediction market platform toward Wall Street liquidity, a move that could broaden its U.S. Investor base if institutional adoption follows.
Polymarket, the online prediction market platform that allows users to trade contracts on event outcomes, has hired Lisa Mantil, a nearly three-decade veteran of Goldman Sachs, to lead its institutional growth efforts, according to a CNBC report published September 29, 2026.
Mantil spent approximately 29 years at Goldman Sachs before joining Polymarket, according to the CNBC report. Her specific role title and compensation terms were not disclosed in the report. What would reveal those details is a formal company announcement or a regulatory filing, neither of which was publicly available as of publication.
Polymarket operates prediction markets where participants buy and sell contracts tied to the probability of future events, with prices fluctuating between zero and one dollar based on crowd-assessed likelihood. The platform has attracted significant retail trading volume in recent years, particularly around U.S. Political and economic events.
The platform's decision to hire a senior Wall Street figure is specifically aimed at attracting institutional traders, according to the CNBC report. Institutional participation in prediction markets has historically been limited by regulatory uncertainty, platform liquidity constraints, and the absence of familiar market infrastructure such as prime brokerage relationships and custodial services.
Polymarket is incorporated and operates with a focus on U.S. Market participants, making Mantil's mandate directly relevant to U.S. Investors and trading desks. Institutional traders such as hedge funds and proprietary trading firms require deeper order books and tighter bid-ask spreads than retail-dominated platforms typically provide. Mantil's Goldman background in capital markets would position her to address those structural gaps, though whether or how quickly she will do so is not yet established by any public record.
Prediction markets occupy a legally ambiguous space in the United States. The Commodity Futures Trading Commission, the primary federal regulator of derivatives, has jurisdiction over event contracts under the Commodity Exchange Act. In 2023, the CFTC moved to block certain political event contracts offered by platforms including PredictIt, citing concerns about their classification as gaming or gambling. The regulatory status of Polymarket's specific contract types under current CFTC rules has not been resolved in any final agency order publicly available as of this writing.
Polymarket previously faced a CFTC enforcement action in 2022 in which the company agreed to pay a 1.4 million dollar civil monetary penalty and wind down operations for U.S. Persons, according to a CFTC order published at that time. Whether Mantil's role involves navigating a renewed push for CFTC compliance or registration is not stated in the CNBC report.
The broader context for this hire is growing institutional interest in alternative data and probabilistic markets. Several U.S. Asset managers and quantitative hedge funds have used prediction market prices as supplementary signals for portfolio positioning, particularly around Federal Reserve policy decisions and U.S. Election outcomes. Formalizing institutional access to Polymarket's liquidity pool could increase the platform's contract volume and tighten pricing, which would benefit all participants through narrower spreads.
No financial figures for Polymarket, such as annual revenue, assets under management equivalents, or contract notional volume, were disclosed in the CNBC report. Those figures are not available in any public SEC filing because Polymarket is a private company and is not registered as a public reporting entity with the Securities and Exchange Commission.
The effectiveness of the institutional outreach strategy Mantil will lead depends on factors including CFTC regulatory clarity, the platform's ability to build compliant onboarding infrastructure for institutional counterparties, and whether major trading firms conclude that prediction market liquidity is sufficient to justify the operational costs of participation. None of those outcomes are determinable from currently available public records.
