JPMorgan Chase's investment banking fees have increased by a mid-teens percentage in the first quarter, according to Chief Operating Officer Jennifer Piepszak. The growth has been supported by a revival in dealmaking amidst a robust U.S. economy, a trend observed across Wall Street.

Piepszak expressed optimism regarding a potential rebound in initial public offerings, stating, "We think we should see a real resurgence." While mergers and acquisitions may experience a slower recovery, she noted a growing confidence among companies in engaging in deals.

Furthermore, trading revenues have seen a rise of low double-digit percentages, Piepszak added. JPMorgan shares saw a 1.3% increase to $274.44 in afternoon trading.

Echoing sentiments, Goldman Sachs CEO David Solomon highlighted the market's positive response to the Trump administration's focus on economic growth. Solomon noted, "The market believes that a more growth-oriented agenda will spur investment," citing increased enthusiasm among market participants.

However, Solomon cautioned that uncertainties in policy details could introduce market volatility despite the prevailing optimism.
