Who Replaced Mark Cuban on Shark Tank?
Kendra Scott and Rashaun Williams joined the permanent Shark Tank cast in Season 18 after Mark Cuban left the regular panel following Season 16.
Kendra Scott and Rashaun Williams are the two new permanent sharks in Season 18, following Mark Cuban's departure from the regular cast after Season 16. The cast changed in stages: Season 17 featured guests alongside the returning investors, and ABC later promoted Scott and Williams to permanent roles.
Daniel Lubetzky is part of that returning cast too. He became a regular shark in 2024, so his promotion came before Season 18. He is a returning regular; Scott and Williams are this season's additions.

What Changed in Season 17?
ABC's May 2025 fall schedule announcement described Season 17 as featuring guest sharks throughout the season. The show continued with its returning investors rather than announcing a single new permanent shark to take Cuban's place.
The on-air agreements continued too. Our index records 54 agreements from 72 Season 17 pitches across eighteen episodes, a 75 percent on-air deal rate. That describes what founders accepted on television; it does not show how many agreements became completed investments afterward.

Scott and Williams Join the Permanent Cast
ABC announced the two promotions on July 7, 2026. Scott and Williams join Barbara Corcoran, Lori Greiner, Robert Herjavec, Daymond John, Daniel Lubetzky and Kevin O'Leary, bringing the permanent Season 18 lineup to eight sharks.
Scott founded her jewelry and lifestyle company and serves as its executive chairwoman and chief visionary officer. Williams is the founder and chief investment officer of Harbinger Sports Partners, with a background in venture capital. Both had appeared as guests before joining the regular cast.

Who Is Joining as a Guest?
The new permanent roles sit alongside a separate Season 18 guest lineup. MrBeast and Beast Industries CEO Jeff Housenbold appear in 'Beast Mode', the September 30 premiere, followed that night by Erin and Sara Foster in 'Favorite Daughters'.
Steven Bartlett made his guest debut in 'Diary of a Shark' on October 7. Mindy Kaling is scheduled for 'The Mindy Project' on October 14. J.J. Watt is also an announced guest, with no episode date in ABC's current listings. These guest appearances do not make them Cuban's permanent replacements.
If you want to watch the current cast, start with the Season 18 listings on ABC or Hulu. Use the episode titles to find a particular guest; ABC lists next-day Hulu streaming for the announced episodes.
