$11.49 millionVerdict

In 2013 a 16-year-old fell through a torn trampoline at Cosmic Jump, an indoor trampoline park in Houston, fractured his skull and suffered a traumatic brain injury. After a two-week trial in February 2016, a Harris County jury found the park grossly negligent and awarded $5.485 million in compensatory damages and $6 million in punitive damages. His lawyers believed it was the largest verdict in the country against a commercial trampoline park.
