The NBA season opened with the league’s most-watched Opening Night in five years and its most-watched Opening Night game in three.
Tuesday’s NBA’s Opening Night doubleheader averaged 3.3 million viewers on TNT, up 17% from last year and the highest average since 2017. The five-year high was largely driven by a sharp increase for the Sixers-Celtics opener, which posted a 1.7 rating and 2.98 million viewers — up 31% in ratings and 36% in viewership from last year (Bucks-Nets: 1.3, 2.20M) and the most-watched early game on Opening Night since the aforementioned 2017 edition (Cavaliers-Celtics: 5.60M).
The previous high was 2.95 million for the same Sixers-Celtics matchup in 2018, a figure that it should be noted did not include out-of-home viewing.
The big gains came despite formidable competition in the Philadelphia market. The Phillies’ NLCS Game 1 and a Flyers game both aired on national television in the same window.
The Lakers-Warriors nightcap averaged 3.55 million viewers, up 4% from the same matchup last year and the league’s largest Opening Night audience in three years (2019 Clippers-Lakers: 3.58M) and the fourth-largest in the past nine years. Ratings were not immediately available. The Warriors’ easy win also ranks as TNT’s most-watched NBA game overall since that 2019 Opening Night.

NBA Opening Night viewership, past decade
The NBA games trailed both of Tuesday’s MLB Postseason contests — Game 5 of the Guardians-Yankees ALDS averaged 4.95 million on TBS and Game 1 of the Phillies-Padres NLCS 4.10 million on FS1 — but came out ahead in the key young adult demographics. Lakers-Warriors finished as the day’s top program on any network in adults 18-49 (1.4), 18-34 (1.3) and 25-54 (1.5). Sixers-Celtics placed second in 18-49 (1.2) and 18-34 (1.1) and third behind Guardians-Yankees in 25-54 (1.3).
In addition to the five-year viewership high, the Opening Night games also averaged a record share of 6.2% — up 32% from last year (4.7). As the number of viewers watching linear television declines, audiences will tend to make up a larger percentage of the shrinking linear TV audience than in years past.
