Viral Claims and Support Email
An image of a Rockstar Support response went viral after it stated a physical copy would be available in the following months. The email was authentic but referred only to the already-announced box edition that ships with a download code rather than any disc.
Industry Confirmation of No Disc Plans

The Hollywood Reporter reported that a source with knowledge of Rockstar's strategy confirmed there are no plans to print discs for GTA 6 at launch or afterward. A separate Polish website report claiming a December disc release was also incorrect.
Retail and Player Context
Some retailers have declined to carry the physical edition because it lacks a disc. An IGN poll found that more than 70 percent of respondents plan to purchase the $100 Ultimate Edition rather than the standard version.
