Polymarket has appointed former Goldman Sachs partner Lisa Mantil as head of institutional business growth to drive efforts in attracting Wall Street capital and liquidity. Mantil brings nearly 30 years of experience from Goldman Sachs, where she most recently oversaw the bank's ETF Accelerator platform that assists clients in launching investment products. The hire signals Polymarket's push to expand its institutional business following the official launch of its U.S. exchange in May. Sources indicate the platform has discussed conducting block trades in the U.S. market, with related functionality reportedly nearing readiness, though Polymarket declined to comment on specific progress.
