The Optimal Sports Ecosystem Index revenue tracker’s 8-week trend declined -2% y/y (the 12-week trend is flat – we note -220 bps inflection). By sector, Sports Fandom’s 8-week spending trend is weakest (-15% y/y primarily due to -15% T8W y/y at Ticketmaster) and Sports Participation spending is down -3% (transactions down -9%), while Sports Betting spending is up +3%.

NKE beat Q3 estimates; the share price is down over -15% on guidance, primarily sales in China, impacts of oil prices, geopolitical disruption, & tariffs (as we have noted, “canary in the coalmine, very early indicators are showing traction), weekly analysis below.

CALY (+): Spending continues to increase +33% y/y on a T8W basis while digital traffic continues to increase +11% y/y (we do note slight negative inflections between shorter-term and longer-term trends for both).

GRMN (+): A few weeks ago we noted struggling trends for GRMN, but spending is now up +39% y/y on a T8W basis (and inflecting +21% relative to longer-term trends) as sales this week measured its third highest nominal value since September 2019 and highest since December 2024.

LUCK (-): Spending is down -36% y/y and digital traffic is down -6%, in conjunction with -21% decel in spending and -2% decel in foot traffic.

EA (-): Spending is down -5% T8W y/y and decel is -12% compared to longer-term trends, while digital traffic is down -10% T8W y/y (decel is -7%).

Equity performance for both the Equal-Weight (+3.3% w/w) and Cap-Weighted (+2.0% w/w) Optimal Sports Ecosystem Indices improved relative to last week, as did the Optimal Sports Fandom Index (+4.5% w/w), Optimal Sports Betting & Data Index (+1.6% w/w), and Optimal Sports Participation Index (+3.3% w/w).
