US Theme Park Stocks Lose $160 Million in a Day

Six Flags Entertainment Corporation (NYSE: FUN), the U.S. theme‐park operator, closed today’s session on the New York Stock Exchange at $19.75 per share, down 5.91%. Trading volume was about 2.28 million shares. The company’s market capitalization fell by roughly $110 million, to around $2 billion (approximately ₩2.8 trillion).

In recent months, Six Flags has overhauled its leadership team. On July 15, it named Mark Pauls—formerly of Hershey Family Entertainment—as Chief Operating Officer, and in June it brought in Ash Walia as Chief Financial Officer. Meanwhile, a class-action securities lawsuit tied to the Cedar Fair–Six Flags merger, filed in November 2025, remains in its early stages, posing ongoing financial and reputational risks.

Six Flags Entertainment was created in July 2024 through its merger with Cedar Fair, making it the largest regional theme-park and water-park operator in North America. Trading under the ticker FUN, the company now runs more than 20 theme parks and over 10 water parks and resorts across 13 U.S. states and regions—including Canada and Mexico—with marquee properties such as Cedar Point and Knott’s Berry Farm.
