NBA: Will LeBron James Sign By…?

Platform comparison

Market context

LeBron James, currently in his 22nd NBA season with the Los Angeles Lakers, will need to negotiate his next contract before the end of 2026. The 40-year-old forward signed a two-year, $101 million deal in August 2023 that runs through the 2024–25 season, with a player option for 2025–26 worth approximately $51 million. His decision on that option—expected around June 2025—will determine whether he enters free agency or triggers an extension conversation with the Lakers.

Historical precedent suggests veteran superstars of James's calibre typically resolve contract situations swiftly once they signal intent. When Kevin Durant negotiated with the Phoenix Suns in 2023, his agreement came within weeks of the free agency window opening. Similarly, LeBron's own previous signings with Miami and Cleveland occurred within days of becoming available. The 0% implied probability reflects genuine uncertainty about whether he will remain an active player through 2026 rather than scepticism about his ability to secure terms; retirement remains a material outcome that would trigger a "No" resolution.

Traders should monitor the Lakers' playoff performance through spring 2025 and any public statements from James or his representatives regarding his future intentions. The NBA draft lottery in May 2025 and subsequent free agency period beginning in late June will provide the first concrete timeline. Additionally, any significant roster changes or coaching adjustments at Los Angeles could influence his calculus, though James has demonstrated loyalty to the franchise since joining in 2018.
