As with previous years of the tournament, a corresponding digital compendium for Dota 2 was released before the event, allowing the prize pool to be crowdfunded. Known as the “Battle Pass”, 25% of revenue made by it was sent directly towards the tournament’s prize pool.
The tournament initially began with the Commonwealth of Independent States (CIS), China, Europe, North America, South America, and Southeast Asia regional qualifiers in June 2017. Prior to the main event on August 2–5, two separate best-of-two round robin groups consisting of nine teams each were played, with the bottom placed team of each group being eliminated. The remaining 16 teams moved on to the double elimination main event at the KeyArena in Seattle from August 7–12, with the top four finishing teams from both groups advancing to the upper bracket, and the bottom four advancing to the lower bracket. The first round of the lower bracket was treated as single-elimination, with the loser of each match being immediately eliminated from the tournament. Every other round of both brackets was played in a best-of-three series, with the exception being the Grand Finals, which was played between the winners of the upper and lower brackets in a best-of-five series.
