"In high-frequency trading (HFT), firms like Citadel Securities and Two Sigma leverage advanced machine learning algorithms to execute trades at lightning speed. These algorithms analyze market data in real-time, identifying arbitrage opportunities and executing trades within milliseconds. 

The application of AI in HFT has led to increased market efficiency, as these algorithms can capitalize on price discrepancies that exist for only a brief moment. The speed and precision of AI-driven trading systems have redefined competitive dynamics in financial markets, enabling firms to gain significant advantages over traditional trading methods."

Machine learning has been a key part of Jane Street’s work from the beginning; we’ve leveraged a variety of modeling techniques since our founding in 2000. The depth of our reliance on these models has grown dramatically in the last few years as we’ve adopted ever more sophisticated techniques to improve and inform our trading. Traders and researchers at Jane Street build models, strategies, and systems that price and trade a variety of financial instruments. We analyze large datasets using a variety of machine learning techniques, exploring the latest theory and pushing beyond existing performance limits. (What We Do, n.d., n.p.)

Another significant application of AI in trading is seen in JPMorgan Chase, which has implemented AI-driven algorithms to execute trades more efficiently. According to a study conducted by JPMorgan, over 60% of trades exceeding $10 million were executed using algorithms in 2020. 

The bank has developed tools that incorporate machine learning to analyze market data and optimize trade execution, leading to reduced costs and improved speed in executing trades. This strategic implementation has allowed JPMorgan to maintain a competitive edge in a rapidly evolving financial landscape, where speed and accuracy are essential for success. 

The integration of AI in their trading operations exemplifies how major financial institutions are harnessing technology to enhance their trading capabilities. (Asgari, 2024, n.p.)
