A trading bot operating on prediction market platform Polymarket has become one of the most closely watched accounts in esports betting after reportedly turning around $900 into more than $208,000 in profit over a three-month period.

The account, known on Polymarket as TeemuTeemuTeemu, has generated approximately $208,521 in pure profit in a single quarter, according to publicly visible market data on their Polymarket profile.

Polymarket Bot Takes Advantage of Market Delays

While Polymarket hosts a wide range of political, financial, and cultural markets, the bot’s activity is focused almost exclusively on esports, primarily live matches in League of Legends and Dota 2.

Rather than relying on long-term predictions or tournament winners, the bot targets short-term, in-play markets. It continuously monitors live games, ingesting official match data and parsing broadcast information faster than the market can react. When a kill, objective take, or decisive teamfight occurs, Polymarket prices often lag behind by a matter of seconds.

Those brief delays are where the bot operates. It enters positions while odds are still mispriced and exits almost immediately once the market updates.

The bot’s performance has sparked discussion within the Polymarket and esports betting communities. Many users are apparently now attempting to build or copy similar systems, leading to increased competition on popular live markets.

How long that advantageous window remains open is another question. As more automated systems enter the market and pricing mechanisms improve, it’s possible we see Polymarket and other prediction markets attempt to crack down on this.

TeemuTeemuTeemu Biggest Polymarket Wins

While these types of predictions would usually just see marginal gains (but gains nonetheless), TeemuTeemuTeemu has seen some huge wins on Polymarket.

Their biggest win was almost $90,000 profit on Dplus KIA to win a game against Hanwha Life Esports, while they’ve also made significant profits from large amounts placed on likely predictions, such as $13,193.91 on G2 to win a game against TOP Esports, which returned $19,005.86.

Suffice to say, there is some serious cash to be made in Polymarket’s esports prediction markets, but you’re going to have to be quick if you want to really make the most of it. Or, perhaps, just create a bot.
