Quantitative trading company's bot demonstrates impressive market prediction skills, achieving profits on 23 out of 25 days

A remarkable trading phenomenon has emerged on Polymarket. According to on-chain data tracking, an address formerly known as "JaneStreetIndia," now renamed "Account88888," has shown astonishing trading performance—profiting on 23 out of 25 days, with daily gains ranging from $5,000 to $33,000, and a total net profit approaching $360,000.

**Behind the scenes: Professional-grade bot's precise arbitrage**

Industry insiders believe that this account is manipulated by a trading bot developed by the well-known quantitative trading firm Jane Street. The bot exhibits typical characteristics of algorithmic trading—employing a two-way betting strategy during the early market prediction phase, exploiting periods of low market liquidity for arbitrage. Its operation involves risk-hedged bets with a total investment cost of less than $1.

**How automated trading dominates prediction markets**

The reason such bots can maintain long-term profitability in prediction markets like Polymarket mainly depends on several factors. First, automated trading systems can capture market mispricings at speeds unattainable by humans. Second, the algorithmic advantage accumulated by quantitative trading firms allows them to accurately assess the fair value of assets in the early stages of the market. Finally, the inherent characteristics of prediction markets—binary event outcomes and high volatility—provide fertile ground for the bot's arbitrage strategies.

The performance of this trading address also reflects a trend: traditional quantitative trading giants are extending their expertise into emerging niches within the crypto ecosystem.
