As of early 2026, the title for the steepest roller coaster in America is held by TMNT Shellraiser at Nickelodeon Universe in New Jersey, which features a terrifying 121.5-degree drop. This "beyond-vertical" plunge is the steepest in the world, not just the U.S. However, a major new contender, Storm Rampaging Run, is set to open later in 2026 at Six Flags Over Texas, which will feature a 95-degree "Giga Dive" drop from a height of 308 feet. While the Shellraiser remains the winner for the absolute "angle" of the drop, the new Storm coaster is expected to be more intense due to its massive scale and speed. For 2026 thrill-seekers, America has become the world's "steepest" playground, offering several coasters that drop at angles far sharper than a straight 90-degree vertical fall.
