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.

Business Credit card issuers ranked: amex leads with 38% share. The race among business credit card issuers is becoming sharper, and new data from PaymentsJournal, drawing on research by Javelin Strategy & Research, puts clear numbers on who is winning it. American Express holds 38% market share among business credit cardholders, making it the clear frontrunner. Bank of America sits second at 33%, with Chase close behind at 29%. Capital One and Wells Fargo round out the top five. The rankings come from Javelin's report, Small Business Credit Cards: A $1 Trillion Opportunity for Issuers, Networks, and Fintechs, which maps the competitive landscape across pricing, rewards, fees, and account terms. What the numbers suggest is a market where the top three issuers are genuinely close in reach, even if American Express holds the lead. Which raises an obvious follow-up: what separates a 38% player from a 29% one in a space where the cards themselves can look broadly similar? A market heading towards $1 Trillion. The context matters here. Javelin projects that small business credit card transaction volume will exceed $1 trillion by 2027, making this one of the more consequential battlegrounds in commercial financial services. That projection is drawing in not just the established card issuers but also networks and fintechs, all of whom are eyeing a customer base that ranges from sole traders to companies with more complex spending needs. The Javelin research draws on its Small Business Card Bench to evaluate how leading programmes compare across the basics: what they charge, what they give back in rewards, and how their account terms hold up. The picture that emerges, according to the report, is one of widening differentiation. Some issuers are building tailored card portfolios designed for specific business types and spending patterns. Others are offering more standardised products. That gap, the research suggests, is growing. For businesses themselves, the institution behind the card can affect more than just the rewards rate. Cash flow management tools, integration with accounting software, and the quality of expense tracking all feed into the day-to-day utility of a business card. An issuer with a broader suite of financial products has more to offer in that respect, and Javelin's report specifically considers how providers might deepen integration between business cards and wider financial services. Where the competition is heading. The five-issuer ranking reflects a broader consolidation dynamic in the business credit card space. American Express, Bank of America, and Chase together account for the majority of business cardholders in Javelin's data, leaving Capital One and Wells Fargo competing in a market where the top three already have strong purchase on customer relationships. That does not mean the rankings are fixed. The Javelin report flags major developments reshaping the market, alongside associated risk considerations, without specifying which developments it means in the publicly available summary. Fintechs entering the space with embedded card products and network-level changes are among the structural forces that could shift market share over the period to 2027. For issuers outside the top three, the question is whether product differentiation or distribution can move the dial when American Express, Bank of America, and Chase are already the default choice for a combined majority of businesses. For the leaders, the challenge is whether a $1 trillion market creates room to grow without simply fighting over existing cardholders. American Express heads into that environment with the largest share. Whether its 9-percentage-point lead over Chase is durable or erodes as fintechs and networks raise their own game is, for now, an open question the data does not yet answer.
Bank of America maintained its Buy rating on Capital One Financial with a $253 price target, representing 11.3% upside potential. The rating comes as Capital One integrates its Discover acquisition, completed in May 2025. Capital One's domestic credit card loans totalled $258.9 billion in July, growing 1.92% year-over-year, down from 2.58% growth in June. BofA analyst Mihir Bhatia expects loan growth to remain subdued until integration headwinds clear. Despite slower card growth, credit quality improved. The domestic card net charge-off rate fell 26 basis points to 4.12%, outperforming historical averages. Auto loans showed stronger momentum, growing 12.05% annually to reach $90.5 billion. BofA cited expected expense synergies, capital-return potential, and improving credit trends as reasons for its positive outlook, despite risks from economic uncertainty and regulatory concerns.
