Hours after Donald J. Trump won the race for the White House, scores of regulations that have reshaped corporate America in the last eight years suddenly seemed vulnerable. While many questions remain about how President-elect Trump will govern, a consensus emerged in many circles in Washington and on Wall Street about at least one aspect of his impending presidency: President-elect Trump is likely to seek vast cuts in regulations across the banking, health care and energy industries.

The idea of a Trump presidency triggered a sense of dread among many people in the liberal-leaning technology business. Trump is seen as less favorably disposed toward the concentration of power among the handful of large companies that dominate the internet, including Facebook, Google and Amazon, said Glenn Kelman, chief executive of Redfin, an online real estate firm. Trump has called for the rejection of AT&T’s bid for Time Warner. Still, analysts expect that he will appoint antitrust regulators at the Federal Trade Commission and Justice Department who will largely follow traditional Republican approaches to the free market. Trump will be under pressure by major telecom and cable firms to roll back aspects of net neutrality. The rule inhibits how broadband providers manage traffic on their networks to ensure any website is equally accessible to consumers. Telecom and cable firms continue to challenge the rules in court and Mr. Trump, with the encouragement of Republicans in Congress, may seek to abandon the regulation.
