NBA commissioner Adam Silver is finalizing a contract extension that is expected to take him through the end of the decade, sources told ESPN on Saturday.

The completion of formal negotiations with the Board of Governors on a new deal keeps Silver -- nearing his 10th anniversary as commissioner -- on course to pursue the NBA's next set of major objectives: a new media rights deal and league expansion.

Largely different than his predecessor David Stern, Silver has built a reputation of pursuing more consensus and partnership with ownership, management and players. He's been able to maintain respect -- and even popularity -- among those constituencies despite difficult decisions and negotiations.

Silver, 61, has driven some dramatic initiatives, including the introduction of the Play-In and In-Season tournaments, player participation legislation, draft lottery reform that has disincentivized teams racing to bottom for top draft picks and steadily-rising franchise financial valuations. The implementation of the league's freedom of movement emphasis in 2019-2020 has increasingly gassed up the league's scoring, including a 2023-2024 season that so far includes four of the top 10 offensive teams in NBA history.

Silver completed a new collective bargaining deal with the Players Association in March that assures labor peace through at least 2029 and a reshaped salary cap system that is expected to deliver small and mid-size market organizations a better chance to compete with big market franchises. The league had been pursuing an economic structure that would help spread talent around to more teams -- and that appears to be happening now.

Silver has shown an ability to navigate crises -- most notably by suspending the NBA season following Rudy Gobert's positive test for COVID-19 in 2020 and leading the way for an American sport and societal reaction to the opening weeks of the pandemic. Ultimately, Silver devised an Orlando bubble to restart and complete that 2020 season, salvaging television revenue and player salaries.

Silver also oversaw bans, suspensions and the eventual sales of teams by two problematic NBA owners -- the Clippers' Donald Sterling and the Suns' Robert Sarver.

Silver spent eight years as the league's deputy commissioner before succeeding Stern in 2014, and was a consensus choice to replace him when Stern announced his retirement date in 2012.
