Polymarket has hired Lisa Mantil, a Goldman Sachs equities executive who made partner at the bank in 2018, as the prediction market platform moves to attract institutional capital and deepen Wall Street liquidity ahead of a reported funding round at a roughly $21 billion valuation.

Mantil spent nearly two decades at Goldman, joining as a managing director in 2009 before her 2018 promotion to partner. Her background sits in program trading and equities execution — the infrastructure layer that allows large institutional orders to move through markets efficiently. That expertise maps directly onto Polymarket's core problem as it scales: how to get large, risk-managed capital comfortable trading on a venue originally built as a crypto-native experiment.

Who else has Polymarket hired?

Mantil's arrival is not an isolated move. Polymarket has added at least four senior leaders in roughly five weeks, reshaping a C-suite that now resembles a traditional exchange operator more than a DeFi startup.

The most prominent prior hire is Warren Jenson, formerly finance chief at Amazon and Nielsen, who joined as the company's first-ever CFO. The recruitment drive has also drawn talent from Robinhood, Nasdaq and Coinbase, covering:

• compliance
• product development
• risk management
• marketing

The pattern is consistent: Polymarket is buying the operational muscle that regulated trading venues require, rather than building it slowly from within.

What does the CFTC-regulated exchange change?

The structural detail matters most. Polymarket now operates a CFTC-regulated exchange in the United States, run as a separate entity from its international business, which continues to settle trades on-chain. That bifurcation lets the company court US institutional participants who cannot touch an unregulated offshore venue, while preserving the on-chain rails that built its original user base.

The company is also rebuilding its on-chain trading capabilities alongside the regulated US offering, signaling it intends to run both tracks in parallel rather than migrating entirely into a conventional exchange structure.

The setup places Polymarket in direct competition with Kalshi, the other major US prediction market operator holding CFTC approval. Kalshi built its business regulatory-first from inception. Polymarket is retrofitting that same institutional legitimacy onto a platform that already commands brand recognition and user traction — a different sequencing of the same endgame.

Why are trading firms circling prediction markets?

Mantil's hire lands amid a broader shift in how traditional finance firms view event contracts. Firms including DRW and Susquehanna are reportedly hiring traders specifically to participate in prediction markets, drawn by liquidity provision and arbitrage opportunities rather than directional betting.

For Polymarket, that dynamic cuts both ways. Proprietary trading firms bring the depth and two-sided flow that retail-dominated order books lack. But they also demand the execution quality, market data and risk controls that a Goldman program-trading veteran exists to build. Mantil's mandate, in effect, is to make Polymarket a venue where a DRW or Susquehanna can operate at scale.

What comes next?

The reported funding round — which would value Polymarket at approximately $21 billion — will test whether investors accept the thesis that prediction markets can become a permanent fixture of US market structure rather than a cyclical novelty. With a CFTC-regulated entity live, a conventional CFO installed and Wall Street execution talent now in place, the company has assembled the pieces for institutional distribution. The remaining question is execution speed: whether Polymarket can convert its hiring spree into sustained institutional volume before Kalshi consolidates the regulated segment.
