Welcome to The Signal, Box Score's Wednesday newsletter. Last week, we introduced the GOATs of the Sports Economy: the rare athletes who move markets, franchise valuations and championship odds all at once. We started with soccer’s GOAT, Lionel Messi. Then, during what should have been a quiet stretch on the sports calendar, the NBA's King made his decision — and reminded us why he's on the list.
LeBron James has decided to join the Philadelphia 76ers for the upcoming season — his fourth team in a 23-year career. On court, he’ll be a welcome addition to a team already bolstered with the off-season acquisition of perennial All Star Jaylen Brown from the Celtics.
For the 41-year-old future Hall of Famer, this could be his last season as a player. But the inevitability of his retirement is warning of not just the end of one of the most decorated careers in pro sports, but also the end of one of the greatest engines of economic prosperity that sports has ever seen.
The Boyd Company, a Philadelphia-area consulting firm, estimates that in his first year alone LeBron’s presence in Philly will generate between $250 million and $430 million in regional economic activity. About two hours after James’ move to the Sixers was announced on Friday, the initial run of No. 23 jerseys available through Fanatics had sold out, including the adult red, white and royal blue Nike Swingman premium editions.
If LeBron’s outsized presence seemingly overshadows winning and losing basketball games, it’s because that’s been the pattern since he was drafted in 2003 by the Cavaliers out of high school. The Cavs' value increased by more than 100 percent, from $222 million in his rookie year to $476 million by the end of his first stint with the team in 2010. The Sixers, who had just 14 national TV appearances last season, are expected in the 2026-27 season to get the league's maximum allotment of 34 nationally televised games, placing them in the stratosphere with the league’s most popular teams — the Los Angeles Lakers, the Golden State Warriors and the New York Knicks.
LeBron’s critics have derided The Decision and his habit of shifting teams to form super rosters, but from an economic standpoint it’s been a masterful strategy to spread his celebrity to several communities. What if Michael Jordan, during the height of his playing days with the Bulls, had decided to leave for another city? After his first retirement from the Bulls in 1993, his value to the Greater Chicago economy was estimated at $1 billion.
The other day when Donald Trump was told about LeBron’s decision, he was asked where he stood on the GOAT question between Bron and MJ. Instead of calling LeBron a racist, Trump might have celebrated him for spurring economic growth and the success of small businesses.
Before joining the Lakers in 2018, LeBron spent his first 15 years in the NBA between Cleveland and Miami. According to an American Enterprise Institute study, restaurants within a 1-mile radius of the stadiums in those cities when he was playing saw their business spike 13 percent and local food service employment increased by 23.5 percent.
The Sixers' last NBA championship came in 1983 with a team led by Julius Erving and Moses Malone. The sports-crazed town wants an NBA championship, and fans know that a team with LeBron, Joel Embiid and Jaylen Brown has a great chance of making it to the finals and winning if everybody stays healthy. But winning and staying healthy are never a certainty in pro sports. What is certain is that LeBron will fill up seats and build interest in the team that will trickle down to small businesses and their employees and the vendors who serve them.
Like one of the best Philadelphia stories ever told — Rocky Balboa — by the time you’re done watching LeBron’s impact on the city, you won’t remember or care, perhaps, that he didn’t win his fifth championship ring.
The $8 Billion Man
How much will LeBron James be worth to the Philadelphia 76ers franchise? He's already helped create nearly $8 billion in value for his three previous teams. Here's how the numbers add up.
When LeBron arrived in Cleveland in 2003, the Cavaliers franchise was worth $222 million and then increased more than 2x to $476 million during LeBron's first seven seasons. (The valuation dropped to $355 million when he left for Miami in 2010.)
Total increase: $254 million
The Miami Heat were valued at $188 million when LeBron arrived in 2010, and that valuation rose to $364 million before he returned to Cleveland in 2014.
Total increase: $176 million
In his return, LeBron doubled the value of the Cleveland Cavaliers again. The franchise went from a $515 million valuation in 2014 to $915 million in 2015 and crossed the billion mark at $1.1 billion when the Cavs won the NBA title in 2016. When LeBron left for Los Angeles in 2018, the Cleveland Cavaliers were worth $1.325 billion.
Total increase: $810 million
The numbers get staggering after his move to the Lakers in 2018, though at this point the LeBron Effect merges with an explosive rise in NBA franchise values. From 2018-2025, the Los Angeles Lakers increased in value from $3.3 billion to $10 billion, the amount Guggenheim Partners CEO Mark Walter paid for the team in 2025.
Total increase: $6.7 billion
Total Increase in Franchise Valuation for LeBron's Teams:
$254 million + $176 million + $810 million + $6.7 billion = $7.94 billion 🐐
