Why the 2026 NBA Finals Was a Slam Dunk for Tatari Clients

The last time the New York Knicks won an NBA championship, Nixon was in the White House, The Godfather was a box office smash, “TikTok” was just a sound a clock made, and television advertising meant buying spots on just three networks. Imagine that. This June, after half a century, the Knicks finally brought a title back to New York, and in doing so, they delivered the most-watched NBA Finals since Michael Jordan's Chicago Bulls dynasty ended in 1998.

For Knicks fans, this was catharsis. For the advertisers who placed their bets early on the 2026 NBA Finals, it was one of the best values in live sports this year.

An NBA Showdown Built for Prime Time

The New York Knicks versus the San Antonio Spurs was a matchup that the league and advertisers could only dream about. The largest media market in the U.S. facing a team with one of the game's most compelling stars in a generation, Victor Wembanyama. It was appointment television before a single tip-off.

And the NBA desperately needed that.

Years of declining Finals viewership had cast a shadow over the league's national appeal and quietly suppressed enthusiasm (and ad prices) for NBA Finals inventory. Last year's NBA Finals averaged less than half of what 2026 would ultimately deliver. This year's Finals put an end to any doubt about the league’s popularity.

Breaking Down the Numbers

Early games delivered solid numbers. Then the Knicks started making improbable comebacks. Even casual New York fans started watching, and the rest of the country followed. Here’s what viewership numbers looked like, according to Nielsen:

• Game 1: 16.9M viewers

• Game 2: 16.4M viewers

• Game 3: 23.8M viewers, and the strongest Game 3 since 1998, up 159% year-over-year, peaking at 26.3M in the closing minutes. The highest-rated TV program since the Super Bowl. You read that correctly. President Trump was also in attendance - the first sitting U.S. president to attend (fall sleep at) an NBA Finals game.

• Game 4: 20.9M viewers, and the most-watched Game 4 in ABC history, up 123% year-over-year, as the Knicks erased a 29-point deficit in the largest comeback in NBA Finals history. 

• Game 5: 24.5M viewers tuned in to witness Jalen Brunson drop 45 points to help New York end its 53-year drought. 

Series average: 20.6 million viewers. The most-watched NBA Finals since 1998, double the viewership from last year.

National TV advertising across ABC and ESPN totaled $82.2 million through the first three games alone with 4.1 billion impressions, versus 2.7 billion for the same window a year ago, according to iSpot.tv.

Tatari Clients Played Offense

The NBA Finals CPMs are typically negotiated in advance. Buyers commit to inventory long before anyone knows whether the New York Knicks or any other team with a massive market footprint will make a run. Those prices reflect historical viewership, not what actually happens on the court. Last year's NBA Finals drew numbers that prompted real questions about the league's national appeal. That narrative shaped how inventory was priced heading into 2026 and left opportunity on the table for advertisers paying attention. 

As the Knicks made their run, some buyers recognized what was coming and moved quickly. The remaining inventory was still priced against a very different NBA Finals than the one that actually aired. The brands that locked in their spots got the benefit of 20.6 million average viewers at rates set before anyone could imagine the viewership numbers. Coupled with savvy negotiators from Tatari’s Media Buying team, our clients achieved CPMs discounted at more than 75% below rate card expectations.

The Final Word

The NBA carried questions about their ratings heading into this postseason. The 2026 Finals erased it in five games and reminded every advertiser of the same lesson: the best time to buy a tentpole is before the market agrees it's one. 

The wait of 53 years is over for Knicks fans. The window for getting ahead of the next big sports moment won't last that long.
