A new NBA season always carries fresh storylines, but few have opened with an offseason quite as explosive as 2026/27. Here’s everything you need to know before opening night.
## When It Starts
The league’s 81st regular season tips off Tuesday, October 20, 2026, with the defending champion New York Knicks raising their first championship banner in more than 50 years at Madison Square Garden before hosting a rebuilt Philadelphia 76ers squad. Two more opening-night games follow, including a rematch of the 2026 Western Conference Finals between Oklahoma City and San Antonio.
## The Offseason That Changed Everything
Few offseasons have moved as fast as this one. LeBron James left the Los Angeles Lakers after eight seasons to sign with Philadelphia, joining a 76ers roster that had already added Jaylen Brown in a blockbuster trade with Boston. Elsewhere, Giannis Antetokounmpo was dealt from Milwaukee to Miami, pairing him with Bam Adebayo. Our full breakdown of the biggest free agency and trade moves covers every domino that fell this summer.
## Why the Knicks Enter as Favorites, But Not Alone
New York’s five-game triumph over San Antonio in the 2026 Finals, powered by Finals MVP Jalen Brunson, cemented their status as the team to beat. But with Philadelphia suddenly loaded and Miami adding a former MVP, our championship favorites breakdown explains why this title race looks wide open by design under the current collective bargaining rules.
## Key Dates to Know
