Polymarket Names Warren Jenson as Its First Chief Financial Officer

Polymarket named Warren Jenson as its first chief financial officer on Sept. 10, bringing in a finance executive who previously held the CFO post at Amazon, Electronic Arts, Delta Air Lines, and NBC, the company said. Jenson will report to founder and chief executive Shayne Coplan.

The company described the hire as part of scaling its CFTC-regulated exchange in the United States, growing its platform in other countries, and adding senior leaders. As CFO, Jenson will run the finance organization, set financial and capital strategy, strengthen long-range planning, and build the systems meant to carry Polymarket into its next phase, according to the announcement.

"Prediction markets are changing how the world gets information, and Polymarket is at the forefront of that industry," Coplan said in the release. "We're assembling the team to match the opportunity in front of us. Warren has led finance at some of the most consequential companies in the world, and his experience will be critical to everything we build from here."

Jenson said Polymarket had created a large new global market category and called the opportunity ahead enormous. "I'm joining Shayne and the leadership team to put the capital strategy and operating discipline in place to move quickly at scale and continue to push the frontier of this industry," he said.

Coplan also marked the hire on X, where CoinDesk noted he called Jenson a "true legend" in a post announcing the appointment.

Jenson, 69, brings more than three decades in finance. Amazon named him senior vice president and chief financial officer in September 1999, when he arrived from Delta, where he had been executive vice president and CFO. Before Delta he had been CFO of NBC, then a General Electric division, and earlier worked in GE mergers and acquisitions and investor relations, Amazon said at the time. He later served as CFO of Electronic Arts.

His most recent operating roles were outside pure finance. Jenson was president and chief financial officer of Nielsen, where the company says he led a modernization effort covering finance, strategy, technology, corporate development, and the analytics business. Before that he was president of LiveRamp, running finance and the company's international expansion as it took its data and identity platform into new markets, per the Polymarket release. He sits on the boards of DigitalOcean, Dropbox, and Ripple, and holds bachelor's and master's degrees in accounting from Brigham Young University. At Amazon he succeeded Joy Covey as finance chief and reported to president and chief operating officer Joseph Galli; at NBC he had worked on acquisitions and the structuring of MSNBC, Amazon said. The Polymarket release did not disclose his start date or compensation terms.

The hire lands as Polymarket spends heavily to retake ground in the United States. The company was largely shut out of its home market after a 2022 settlement with the Commodity Futures Trading Commission required it to block American users, CoinDesk noted. Its path back runs through QCX, an exchange it agreed to buy for $112 million; the CFTC granted QCX approval on July 9 after a two-year application process. Federal prosecutors had investigated whether Polymarket let Americans circumvent the block, and FBI agents searched Coplan's home, an episode a company spokesman called political retribution. The probe ended the week before the July 21, 2025 acquisition announcement, CoinDesk reported in 2025.

Money has followed the comeback. On Sept. 1, reports put a new $1 billion raise led by 1789 Capital at a $21 billion post-money valuation, with the firm adding about $300 million on top of roughly $200 million it had already committed, a 40 percent step up from a valuation near $15 billion months earlier, CoinDesk reported. Intercontinental Exchange added a $600 million direct investment on March 27 as part of an equity raise, with up to $40 million more in secondary purchases, following an initial $1 billion commitment in October 2025, ICE disclosed. ICE said the outlay was not expected to materially affect its results or capital returns.

The urgency comes from a rival pulling away. Prediction markets on Kalshi and Polymarket together handled $48.4 billion in August, according to Piper Sandler figures cited by Reuters, with Kalshi at about $40 billion, nearly five times the volume of Polymarket, the former leader. Reuters framed the Jenson appointment as the latest in a series of moves to reverse that slide and grow at home and abroad, in its account of the hire. Polymarket turned six earlier this year, says it has passed $1 billion in annualized revenue, and hired former Uber executive Travis VanderZanden as chief growth officer this year. It also signed LeBron James to promote the platform.

What the company has not said is whether the finance build-out points toward public markets. The Sept. 10 release says nothing about an initial public offering, and IPO timing remains analyst speculation rather than company guidance. The stated mandate is narrower: financial and capital strategy for a regulated exchange that is scaling in the United States while defending its global business against a rival that currently trades a far larger share of prediction-market volume.
