After 27 years at Goldman Sachs, Mantil will lead Polymarket’s expansion into institutional markets, its next wave of growth

NEW YORK, Sept. 29, 2026 /PRNewswire/ — Polymarket, the world’s largest prediction market, today named Lisa Mantil its Head of Institutional Growth. Mantil will lead the company’s work with investment managers, trading firms, corporates and banks, to build the products, infrastructure and liquidity they need to take part in prediction markets at scale.

Prediction markets give institutions something they haven’t had before: a direct way to price and hedge real-world events. Elections, policy decisions, rate moves, regulatory rulings and geopolitical outcomes affect nearly every portfolio. Until now, institutions have largely relied on proxies and correlated assets, with no guarantee those instruments will move in line with the risk they are intended to hedge. Institutional access to Polymarket opens new markets, brings new participants into the category and gives capital a direct way to hedge risks that previously lacked dedicated markets.

At Goldman Sachs, Mantil was a Partner known for her deep relationships with the firm’s institutional clients. Most recently, she built and led the firm’s ETF Accelerator, a platform that helped institutions bring new investment products to market.

“Lisa’s experience and relationships across the institutional world are world class,” said Shayne Coplan, Founder and CEO of Polymarket. “She’s the right person to lead the latest expansion of our business.”

“The opportunity to join Polymarket is a rare chance to help shape an exploding asset class at an inflection point in its development,” said Lisa Mantil, Head of Institutional Growth at Polymarket. “I’ve spent my career guiding institutions as they adopt new products and enter new markets, and I look forward to bringing that expertise to Polymarket as we build the institutional business and expand the role prediction markets can play across investment and risk-management strategies.”

Mantil joins Polymarket after nearly three decades at Goldman Sachs, where she was named Partner in 2018. Throughout her career, she has built the systems that connect institutional capital with new financial products, establishing a track record of taking new ideas from market entry to institutional adoption.
