NBA Announces Key Changes to Emirates NBA Cup Format and Coach’s Challenge Rules

The National Basketball Association (NBA) unveiled two significant changes today, impacting the structure of the Emirates NBA Cup and the implementation of the Coach’s Challenge rule. Both updates are aimed at improving competitive balance and streamlining game operations.

Home Court Advantage for Semifinals Starting 2026-27

In a major shift, the NBA confirmed that beginning with the 2026-27 season, the Emirates NBA Cup Semifinals will be hosted at the home arena of the higher-seeded team in each conference. This change moves away from the current neutral-site format, which will remain in place through the 2025-26 season, with T-Mobile Arena in Las Vegas continuing to host both the semifinals and championship games during that period.

The adjustment will bring a more traditional playoff feel to the Emirates NBA Cup, allowing top-performing teams to be rewarded with home court advantage deeper into the tournament.

Despite the change, the Championship Game of the Emirates NBA Cup will still be played at a neutral venue, keeping the event’s marquee finale in a centralized location that caters to fans and media on a national scale.

Coach’s Challenge Rule Streamlined for 2025-26

In a separate but equally notable development, the NBA Board of Governors approved a change to the Coach’s Challenge rule aimed at accelerating the replay process. Starting with the 2025-26 season, when a Coach’s Challenge is used to review an out-of-bounds violation, the Replay Center official—not the on-court crew chief—will determine whether a proximate foul should have been called.

This builds on a rule introduced last season, which allowed officials to assess whether a foul occurred in the immediate sequence of an out-of-bounds play, but required the on-court lead official to make the call. The updated protocol delegates that responsibility to the centralized Replay Center, which is expected to improve consistency and efficiency during reviews.

The rule change received unanimous support from both the NBA Competition Committee and the league office, highlighting a shared commitment to refining in-game officiating processes.

With these announcements, the NBA continues to evolve its tournament structure and officiating protocols in response to both logistical demands and competitive integrity. Fans can expect a more dynamic Emirates NBA Cup experience and smoother officiating transitions as these changes take effect over the next two seasons.
