Since Grand Theft Auto 6’s last trailer dropped on May 6, 2025, fans around the world have been asking one question over and over: when is Trailer 3 coming? To be fair, they've been asking a lot of other questions too about pricing and PC ports, but this one more than any other.

With Take-Two Interactive confirming that marketing for GTA 6 will kick off in Summer 2026, speculation around the next major video reveal has shifted into high gear.

Below we break down every credible theory currently known online, explain the reasoning behind each, and rank them based on evidence, historical patterns, and official context.

  1. 177-Day Theory

This is by far the most discussed theory among the fans, and it has roots in real data rather than speculation or guesswork. The "177-Day Theory" points to an exact numerical pattern between trailer 3 and the game's confirmed launch date of November 19, 2026. When GTA 6 was delayed from May 26 to November 19, fans noticed something very specific - the gap between those two dates is exactly 177 days, and that number matters because Red Dead Redemption 2 had a 177-day gap between its third trailer and final release.

That parallel has led many to believe May 26 was never going to disappear entirely. Even if the game moved, that date could still function as a logical moment to re-ignite the marketing campaign. What's even more convincing is that it also sits comfortably inside the confirmed summer promotional window. That alignment is what gives this theory weight, as it perfectly fits the broader timeline Take-Two has already outlined.

This is the reason this theory ranks as the most likely and the most credible theory on this list. It combines historical precedent, a specific date, and confirmed summer positioning.
