Goldman Sachs has reported a significant increase in its third-quarter net income, reaching $4.1 billion, supported by robust performance in investment banking and fixed-income trading. The bank's revenue for the quarter was $15.18 billion, with investment banking fees surging by 42% to $2.66 billion and fixed-income trading revenue rising 17% to $3.47 billion. Operating expenses for the quarter increased by 14% to $9.45 billion, largely due to higher compensation costs. Additionally, Goldman Sachs announced its acquisition of Industry Ventures, a venture firm managing $7 billion in assets, further expanding its investment portfolio.
