LeBron’s 76ers debut draws 7.71 million, the NBA’s most-watched opening night ever: what the record means for NBC, advertisers and the Knicks’ new stock

The NBA got the opening number it wanted. The league said Thursday that the 76ers’ 106-100 win over the Knicks on Tuesday averaged 7.71 million viewers on NBC and Peacock, the most for a primetime opening night game in NBA history. The audience peaked at 9.1 million in the 9:45 p.m. ET quarter-hour, as Philadelphia came back to spoil the Knicks’ championship ring night in LeBron James’ first game with his new team.

The full primetime doubleheader, with Thunder-Spurs as the nightcap, averaged 6.41 million, another opening night record. The league also counted more than 700 million social media views across the day, which it called an opening night record as well. In business terms, the number matters for more than bragging rights. It is the first data point of year two of the 11-year, $76 billion media deal, and it lands just as advertisers, a newly public Knicks company and every team chasing a bigger local TV audience are watching what national reach is worth.

The numbers behind the record

The 7.71 million is a combined figure: about 5.98 million viewers measured by Nielsen on the NBC broadcast, plus roughly 1.7 million streaming on Peacock and other digital platforms, tracked by Adobe Analytics. That mix is now standard for NBA games on NBC. It is also the main reason comparisons with the past need care.

The old opening night high was 7.35 million for Heat-Celtics on TNT in 2010, which was also LeBron James’ first game with a new team. Jon Lewis of Sports Media Watch pointed out that Nielsen did not count out-of-home viewing at all until 2020, only fully counted it from 2025, and is in only its second year of blending its viewer panel with “Big Data” from smart TVs and set-top boxes. He wrote that the 2010 game would almost certainly rank higher under today’s method. The record is real, but part of it comes from better measurement.

Even with that caveat, the size of the jump is hard to ignore. Viewership was up 32% from last year’s double-overtime Rockets-Thunder opener, which drew 5.85 million. It was also the largest NBA audience outside Christmas Day since March 1999, when NBC drew 8.37 million for Lakers-Jazz.

The rest of the day was more mixed. Thunder-Spurs averaged 4.85 million, down 5% from last year’s late game, Warriors-Lakers, but still the second-best late window in opening night history. The new 3 p.m. ET matinee, Celtics-Pistons, averaged 2.52 million. That is the biggest audience on record for a weekday afternoon regular-season game outside the holidays, even though some NBC stations moved it to secondary channels. Across all three games, NBC averaged 5.1 million viewers.

Why one night matters to the TV partners

NBC is paying an average of about $2.5 billion a year for its share of the package, and it is leaning harder on broadcast television in year two. It will air 50 regular-season games on its main network this season, up from 39 last season, and ABC will add 21 more. That puts 71 national games on free, over-the-air TV, almost a third of the national schedule, and it is the bet that numbers like Tuesday’s are meant to justify.

The first season already paid off for the networks on the ad side. Data from the ad-spend tracker Guideline showed NBA in-game advertising reached a record $2.11 billion in 2025-26, up 38% from $1.53 billion the year before, mostly because broader reach let the networks charge more per thousand viewers. ABC and ESPN booked about $824.5 million, NBC Sports about $782.2 million and Prime Video about $507.4 million. Streaming alone brought in $874 million, compared with about $10 million the season before.

Media buyers have said this season’s national inventory on Peacock, Prime Video and Disney platforms was close to sold out before tip-off. A record opener does not change prices already locked in, but it strengthens the networks’ position in the scatter market, the ads sold during the season. It also gives NBC a strong first data point as it sells the rest of its expanded schedule. American Express, which put its name on the league’s tip-off broadcast, now has its brand on the most-watched opening night ever.

Last season set a high bar. The 2025-26 regular season averaged 1.78 million viewers per game across the three national partners, up 16% and the best in seven years, and NBC led with 2.8 million per game. Wednesday and Thursday’s games on ESPN, including James’ home debut against Cleveland, and Friday’s first Prime Video doubleheader have not been reported yet. Those numbers will show whether the opening surge reaches past one night.

The Knicks factor, and the stock that starts trading Monday

The timing is useful for Madison Square Garden. MSG Sports is splitting off the Rangers, which means the Knicks are about to trade as their own stock. The remaining company, renamed MSG Knickerbockers Corp., is set to begin regular-way trading as MSGK on Monday, Oct. 27. For a business that will be valued almost entirely on one basketball team, a record national audience on ring night is a timely selling point for investors. The Knicks draw the country’s biggest TV market and now a championship banner, and both showed up in Tuesday’s number.

It also shows where most of the money is. The Knicks’ local games still air on MSG Networks, which belongs to a different company and depends on a shrinking cable base. Fans who wanted to watch the champions on a big national stage Tuesday only needed an antenna or a Peacock subscription. That contrast with the regional model, and with what it costs to follow one team without cable, is part of why the league pushed so many games onto broadcast TV in this deal. The ring night crowd inside the Garden paid a $1,894 average resale price for the same game.

What to watch next

Three numbers will tell more than the record. The first is the ESPN opening week figures, especially Thursday’s 76ers-Cavaliers game, which tests whether James carries a Philadelphia audience outside a marquee matchup. The second is the first regular Tuesday slate on NBC on Oct. 27, which includes Pistons-Knicks. The third is Christmas Day. Knicks-76ers could still finish as the most-watched regular-season game of the year, depending on how strong the NFL games airing opposite the NBA on Christmas turn out to be.

For now, the league has its headline. A year ago, the first night of the new deal drew 5.6 million for the doubleheader and set the tone for a season of gains. This year’s opener beat that by 14%, with a 41-year-old star in a new jersey helping drive it. For the networks paying $76 billion over 11 years, that is the kind of early sign they wanted, as long as the measurement caveats are kept in mind.
