As of February 26, 2026, the market capitalization (or net worth) of Six Flags Entertainment Corporation (NYSE: FUN) is approximately $1.73 billion. This valuation reflects the company's status as a "small-cap" stock following significant market volatility over the past year, during which its market cap decreased by roughly 60%. It is important to note that the current entity is the result of the high-profile merger between Six Flags and Cedar Fair, which closed in 2024, operating under the Six Flags name but utilizing the "FUN" ticker symbol. While the company's net worth has fluctuated—hitting a peak near $4.8 billion in late 2024—it has faced headwinds from shifting consumer spending and the costs associated with integrating two massive theme park portfolios. Despite the lower market cap in early 2026, the company remains a dominant player in the regional amusement park industry, managing 42 parks across North America and leveraging a combined infrastructure that generates billions in annual revenue, even as the stock price works to stabilize in a competitive leisure and hospitality market.
