JPMorganChase Reaches Women's Sports Fans Via Togethxr
JPMorganChase is leveraging media and commerce company Togethxr to engage women's sports fans without official league sponsorships. At events like the Women's Final Four and WNBA All-Star Weekend, Chase activates through pop-up shops, podcasts, and cardholder perks. The bank found only 5-6% overlap between WNBA and NBA card transactions, indicating a distinct audience that is younger and more affluent. Togethxr, founded by athletes Alex Morgan, Sue Bird, Chloe Kim, and Simone Manuel, operates near major events without being a sanctioned partner. This partnership provides brands without league rights a way to reach dedicated fans. The women's elite sports market is projected to reach $3 billion in 2026, driving media companies to offer alternative access points. Chase's strategy focuses on acquiring a new customer base beyond its existing men's sports sponsorships.
SpaceX Seeks $40B Debt to Buy Nvidia Chips
SpaceX, now operating as SpaceXAI after merging with xAI, is negotiating a $40 billion financing package led by Apollo Global Management to purchase Nvidia AI chips for its data center expansion. The package includes $10 billion in bank loans and $30 billion in investment-grade bonds, with Pimco among potential lenders, and is expected to close by 2027. The funds will support AI data center growth, including doubling the chip count at Colossus 2 by December, and SpaceX will also lease capacity to third parties like Anthropic. Investors reacted cautiously; SpaceX shares dipped about 1% to $170 (with a 2.5% drop on October 7 after a 15% rise in five days), while Nvidia rose 0.5%. Bonds maturing in 2056 trade at ~85 cents on the dollar. Following its June IPO raising $86 billion and a $25 billion bond sale, this debt-fueled expansion highlights Wall Street's concerns over AI capital requirements. Nvidia has also launched financing platforms with partners like Apollo and BlackRock to mobilize over $500 billion for AI infrastructure.
