According to data from Equilar, which tracks executive pay in the country’s 500 largest companies by revenue, median pay for CEOs rose to $11 million (not counting inflation). That’s a 6.1%($671,000) increase since the year prior. Even when you account for increases in the cost of living, that raise was still a sizable 4%, or $440,000.

The increase is the highest Equilar has seen in the 17 years since it’s been tracking the metric. It’s also the largest pay raise for CEOs in a single year since 2013.

The stock market may have helped the pay bump along. CEOs receive about 65% of their pay in the form of company stock, and after President Donald Trump’s election win in November, the S&P 500 saw a 9% rally. And now, based on Trump’s tax plan, investors anticipate tax and regulatory cuts that will further boost company profits.

While consumers may have also benefitted from the stock market’s Trump rally via their holdings in mutual funds and 401(k)s, it didn’t quite translate to their paychecks: According to the Bureau of Labor Statistic (BLS), U.S. workers earned a median wage of about $43,380.48 in 2016—a 2.8% raise, or $1,214.65. When you adjust for the cost of living, it’s 0.7%, or $303.

While the comparison isn’t exactly apples to apples, the BLS data and that of Equilar’s does suggest that wealth gap between CEOs and U.S. workers has been gradually widening: In 2015, CEOs were paid 247 times more than an average worker. In 2016, that figure rose to 254 times the average worker.
