Polymarket taps finance veteran Warren Jenson as CFO. 10 Sep 2026 10:25PM Add CNA as a trusted source to help Google better understand and surface our content in search results. Sept 10: Polymarket on Thursday named veteran finance executive Warren Jenson as its CFO, the latest in a series of moves by the prediction market to regain ground lost to rival Kalshi and expand its global and U.S. operations. Jenson, 69, comes with over three decades of experience and has been finance chief at some of the biggest U.S. companies, including Amazon, Electronic Arts, Delta Air Lines and Nielsen. He also serves on the boards of cloud storage provider Dropbox and crypto firm Ripple. "His experience will be critical to everything we build from here," Polymarket CEO Shayne Coplan said. Once a niche corner of the crypto sector, prediction markets - which allow users to trade on the outcomes of various events - have exploded in popularity in recent years. In August, volumes at Kalshi and Polymarket, the two largest prediction market exchanges, stood at $48.4 billion, according to Piper Sandler. But Kalshi's volumes of $40 billion during the month were nearly five times that of previous leader Polymarket, the data showed. Polymarket has been adding more senior leaders across the company as it attempts to reverse the market-share decline, bringing in former Uber executive Travis VanderZanden as its chief growth officer this year. Jenson, who helped shape Amazon.com during its early days, will report to Coplan and aid in strengthening Polymarket's long-term planning as it looks to scale, the company said. Polymarket, which turned six earlier this year and surpassed $1 billion in annualized revenue, has also partnered with LeBron James, the NBA's all-time top scorer, to promote its platform.

Polymarket has appointed Warren Jenson as chief financial officer. Jenson previously served as CFO at Amazon, Electronic Arts, Delta Air Lines, and NBC. He also held senior positions at Nielsen and LiveRamp. The appointment comes as Polymarket scales its CFTC-regulated US exchange and expands globally. As CFO, Jenson will lead finance, set capital strategy, and build infrastructure for the company's next phase. Jenson currently serves on the boards of DigitalOcean, Dropbox, and Ripple. He holds bachelor's and master's degrees in accounting from Brigham Young University. Polymarket operates the world's largest prediction market platform, where participants trade on outcomes of real-world events across politics, economics, science, technology, sports, and culture.

Polymarket vaults past prediction market rivals on App Store as celebs join Lebron in star-studded ad. 10th September 2026 | By Matt Rybaltowski | Reading Time: 5 minutes James' move from DraftKings to Polymarket has resulted in a spike of app downloads, but has also drawn backlash from some RG advocates. As a lifelong football enthusiast, it comes as little surprise that Lebron James' transformative move to Polymarket on Labor Day Weekend served as a harbinger for an even broader announcement by the upstart predictions market operator. Last Saturday, on the same day that Ohio State University made its season debut in college football, James teased a new commercial relationship with Polymarket. James, an ardent Buckeyes' supporter, posted a brief video on social media platform X, where he announced his partnership with the controversial platform. While college football fans watched Ohio State thrash Miami (Ohio) 56-3, industry stakeholders wondered aloud which athletes would join "King James". After all, James indicated in the post that more details would be forthcoming. By Tuesday, the stakeholders received their answer when Polymarket aired a splashy ad that received more than 15.5 million views on James' X page. Following an extended three-day holiday for Labor Day Weekend, Polymarket went live with a colourful 90-second spot directed by award-winning filmmaker Peter Berg, the director of the acclaimed television series Friday Night Lights. The spot, which featured the likes of Eli Manning, Derek Jeter, Richard Sherman, John Leguizamo and Spike Lee, among other celebrities, coincided with the launch of Squads, a new social experience within the US Polymarket app. According to a Polymarket news release, the new initiative will give users a dedicated place to talk markets, share their picks and trade together directly on Polymarket. "People are constantly debating what's going to happen next with their friends and sharing predictions in group chats," said Travis VanderZanden, who serves as chief growth officer at Polymarket. "With Squads, we're bringing the conversation and trading together so friends can follow the events they care about and make their predictions in one place." Vaulting to the top on the App Store. Taking a page from a number of humourous Nike commercials during the 1990s, along with a farcical spot aired by the NFL during Super Bowl LIII, Berg injected slapstick comedy into the ad in an apparent attempt to cater to sports fans. Within a common area inside the Polymarket headquarters, Manning skied high to catch a ball from a jugs machine, while he withstood a low tackle from a defender. "Good morning, Eli," James proclaimed, before the two-time Super Bowl MVP tossed him the football outside an elevator adorned with the Polymarket logo. Seconds later, James exchanged a handshake with Jeter, a Hall of Fame shortstop who won five World Series titles with the New York Yankees. Last month, the Yankees became the first Major League Baseball club to directly partner with Polymarket. The total cost of the ad has not been divulged by Polymarket, but it is fair to estimate that it fell in the millions given the high expenses of bringing aboard a prominent filmmaker such as Berg. Beyond director fees, Polymarket also had to budget for agency and concept fees, set construction and post-production costs that include visual effects, licensing and sound design. In late-August, Polymarket disclosed that it has sought a $21 billion valuation in a new funding round led by Donald Trump Jr's venture firm, 1789 Capital. Polymarket may defend any substantial investment in marketing given the overwhelming impact on customer acquisition that ensued. On Tuesday, Polymarket ranked first on the App Store in downloads for free finance apps, topping archrival Kalshi, Capital One Mobile and prominent payment providers PayPal and Venmo. The company did not immediately respond to a request for comment from iGB. Backlash from anti-problem gambling advocates. A bevy of participating athletes took to social media this week to share their thoughts on the campaign. An X post from Leguizamo, a longtime comedian, encapsulated the fast-paced nature of prediction markets. "It's live trading, you gotta stay on your toes," he wrote, repeating his line from the commercial. Meanwhile, on a post that received 1.2 million views, Manning joked: "Might have to put the pads back on." It prompted Sherman to retort, "now let's try this on the field", in reference to the prediction market app. The 2026 NFL season arguably marks the most contentious battle to attract customers interested in sports betting and predictions, dating back to the historic PASPA decision. For the first full NFL season, traditional sportsbooks such as DraftKings will offer sports-event contracts in the three most populous US states - California, Texas and Florida. Unlike regulated sportsbooks, prediction markets allow customers between the ages of 18 and 21 to trade on sports-event contracts. Craig Carton, a sports talk host with WFAN 660 AM in New York, criticised the athletes for their endorsement of Polymarket. Carton, a recovering compulsive gambler, opined that the "unregulated" gambling markets are driving Americans into bankruptcy and kids out of school. Regulated books prohibit those under 21 from betting on their platform, leading Carton to question the celebrities for promoting the company. "At what point does someone come along where you say no to the offer?" Carton asked. A Bank of America study released on 1 September found that the median deposit account balance of households that participated in online betting was 59% higher than households that avoided the activity. As prediction markets rapidly expand alongside traditional sports betting, the findings have prompted "some to blur the lines between entertainment and investment", according to a proprietary study undertaken by BofA. NFL season opens in the Pacific Northwest. The ongoing battle between states' rights advocates and those who support federal regulations in sports trading is not black and white. Carton indicated in his monologue that engaging in the trading of sports-event contracts amounts to unregulated gambling. Designated Contracts Markets, better known as prediction markets, are regulated on the federal level by the US Commodity Futures Trading Commission. On Wednesday, a CFTC deputy general counsel posted an ad on LinkedIn for a senior position with the commission. It appears that the attorney is seeking assistance in crafting formal rules for event contracts, a set of regulations he described as the "most impactful" the commission has written "in decades". The Polymarket ad campaign debuted less than 48 hours before Wednesday's NFL regular-season opener. The matchup is a rematch of last season's Super Bowl as the Seattle Seahawks host the AFC Champion New England Patriots. Last February in Santa Clara, the Seahawks held the Patriots scoreless through three quarters en route to a 29-13 win. That said, the defending champions are not the favourites to win the Lombardi Trophy this year. Nearly every US operator has installed the Los Angeles Rams as the overwhelming choice to capture the title. As of 6pm ET, the Seahawks had a 62% probability on Polymarket to defeat the Patriots in Wednesday's opener. Conversely, Polymarket traders gave the Patriots a 39% chance to pull the upset. At those odds, a $100 contract on the Pats carries a payout of $247.35. James' multi-year partnership with DraftKings expired earlier this summer, Yahoo Finance reported.
