The finals for this year's International will be held July 18th - 21st at the KeyArena in Seattle, WA. Four-day ticket prices are $99 for General Admission, $199 for Floor seating, and $499 for VIP level.

The International was first held three years ago in Cologne, Germany during Gamescom with 16 of the best Dota 2 teams in the world competing for a grand prize of $1 million.

In 2013 the prize pool was bolstered beyond Valve's contribution by Dota 2 player participation in the Interactive Compendium, driving the total prize pool to over $2.8 million, up from $1.6 million. This year's Compendium will be unveiled soon.

Last year's event had a peak simultaneous viewership of over 1 million people. This doesn't include the international TV broadcasts, or Pubstomp viewing events that took place in over 40 countries in the world.
