The largest prize pool in Dota 2 was the legendary $40 million prize pool of TI10 in 2021. Additionally, TI10 also holds the record for having the biggest crowdfunded prize pool in the history of esports.

When it comes to non-TI events, Riyadh Masters takes the cake. The latest iteration of the annual event boasted a whopping $15 million prize pool, the largest of any non-TI event in Dota 2 history.

No Dota 2 game in competitive history beats the stalemate between Cloud9 and ScaryFaceZ during the qualifiers of Starladder Season 12 in 2015. Most teams would tap out within the hour, but these two champions of attrition lasted over 3 hours in this nail-biter of a game.

On the other hand, teams know when a game is done, and one team that made it apparent was iNfernity Gaming. After a grueling 7 minutes and 50 seconds, the Alliance put iNfernity Gaming out of their misery, with a quick GG call from members of the losing team after losing their tier 3 barracks.

Unsurprisingly, the Grand Magus makes it to the top of the list of contested heroes during TI. The hero simply offers too much utility and lane presence to be ignored while his Spell Steal ultimate turns the enemies’ strengths completely against them. Unless appropriate nerfs hit the hero, he will be a TI mainstay at every event.

With 3 TI wins and several top-four finishes, China holds the record for the most successful region when the TI season comes around. Their success can be summed up with 92 Chinese players having a top-four finish, including 14 Chinese players becoming TI champions.

TI10 was the most viewed of all TIs if we include online viewers streaming the event from all over the world. This stat comes from a combination of YouTube, Twitch, and DotaTV viewers who were glued to the action, resulting in a peak viewership of 2.7 million viewers for the hotly-contested Bo5 main event.

On the other hand, when it comes to the largest arena audience of any TI event, TI9 takes the cake. The event was hosted in the Mercedes-Benz arena in Shanghai, which has an arena capacity of 18,000 seats. The final day of the tournament saw the arena was sold out, setting a new attendance record for a TI event.

Undoubtedly the biggest event in Dota 2 is The International, an annual event that began since the inception of the game in 2011. The International event has only grown bigger throughout the years, with the prize pool starting off at $1.6 million and peaking at $40 million in 2021.
