With Trump starting his second term January 20, law firms are seizing new opportunities for cross-border work in M&A, regulation, and tech, as global challenges reshape client needs.

The optimism stems from his pro-business stance, with Wall Street welcoming his victory and anticipating a strong U.S. market. Concerns linger over potential protectionist policies and the unpredictability of his foreign policy, however, particularly regarding trade wars and competition law. While the M&A rebound is expected to continue, there's also uncertainty about the long-term impact on global businesses. As a result, Trump's second term is leading to more transatlantic alliances.
