Sports Ecosystem trends accelerated further last week as sports betting showed inflection, our sports ecosystem indices largely outperformed the softer overall market, and we update our NKE analysis as our digital traction math continues to show improvement and our thesis is the World Cup is notable as inflection driver.

Summary: (1) Optimal’s Sports Ecosystem revenue tracker accelerated to +1.9% T8W y/y, its second consecutive positive reading and strongest since late February, led by Sports Betting & Data at +13.6% T8W y/y; (2) Sports equity indices largely outperformed the softer overall market, with the Equal-Weight and Cap-Weighted indices (both -0.5% w/w) ahead of the S&P 500 (-1.0% w/w) and Sports Fandom (-1.5% w/w) the lone underperforming subindex; (3) GRMN spending ran up +22.5% T8W y/y and digital traffic ran up +10.9% T8W y/y, both inflecting positively, while LYV spending is down -13.7% T8W y/y and inflecting further negatively; (4) NKE US digital traffic accelerated further to +17.6% T16W y/y and our Online Monitor reached +17.9%, its highest reading since February 2023, though monthly sentiment remains negative.

The Optimal Sports Ecosystem Index revenue tracker accelerated to +1.9% T8W y/y (vs. +1.5% T16W), up from +0.7% last week and its second consecutive positive reading and strongest since late February. Betting & Data spending accelerated sharply again to +13.6% T8W y/y (vs. +10.6% T16W), up from +11.2% last week and remaining the strongest sub-index. Sports Fandom spending was still sharply negative y/y but also accelerated to -10.5% T8W y/y (from -13.0% last week) on -12.4% transactions, partially offset by a +2.1% ticket increase. Sports Participation spending decelerated modestly to -7.2% T8W y/y from -6.5% last week on a -13.5% drop in transactions, partially offset by a +7.3% ticket increase.
Sports equity indices largely outperformed a down market this week. The Equal-Weight Optimal Sports Ecosystem Index (-0.5% w/w) and the Cap-Weighted Optimal Sports Ecosystem Index (-0.5% w/w) both outperformed the S&P 500 (-1.0% w/w). Optimal’s Sports Betting & Data Index (-0.3% w/w) and Sports Participation Index (-0.3% w/w) also declined less than the broader market, while the Sports Fandom Index (-1.5% w/w) had the sharpest decline and underperformed.
GRMN (+): Spending is up +22.5% T8W y/y and inflecting further positively (+5.7% vs. longer-term trend), with digital traffic also positive at +10.9% T8W y/y and inflecting positively (+1.5%). Monthly sentiment is also improving, with Twitter sentiment up +0.4% m/m and news sentiment up +1.8% m/m.
LYV (–): Spending is down -13.7% T8W y/y and inflecting further negatively (-2.9% vs. longer-term trend). Digital traffic remains positive in absolute terms (+4.7% T8W y/y) but is inflecting negatively (-5.4%). Monthly sentiment is still modestly positive, with Twitter sentiment up +2.8% m/m and news sentiment up +0.6% m/m.
Weekly NKE Analysis: Our math suggests World Cup is potentially impacting traction. US digital traffic accelerated further (+17.6% T16W y/y in the most recent week, up from +15.3% last week and -3.7% in mid-March), and global digital traffic continues to accelerate (+8.5% T16W y/y vs. +7.3% last week). Optimal’s Online Monitor accelerated further to +17.9%, again its highest reading since February 2023, while the Optimal’s in-store monitor is flat. Monthly sentiment remains negative, with Twitter sentiment down -11.2% m/m and news sentiment down -12.5% m/m. The big NKE unlock would be a return of basketball shoes to youth fashion – a trend we continue to monitor in our channel checks and polling analysis.
