Regulatory Uncertainty in Antitrust Enforcement: Navigating the New Landscape for Tech and Consumer-Facing Equities

The antitrust enforcement landscape in 2025 has become a double-edged sword for high-growth technology and consumer-facing equities. While regulatory easing under the Trump administration has spurred a surge in tech IPOs and M&A activity, lingering global scrutiny and algorithmic competition concerns continue to create volatility. For investors, the challenge lies in balancing optimism over reduced regulatory friction with caution against unpredictable enforcement shifts.
