With tickets to Austin's first United States Grand Prix selling fast, organisers are considering putting up additional grandstands.
Three-day reserved grandstand seats and general admission tickets for the November event went on sale earlier this month.
The demand, though, has been greater than what the organisers initially forecast, leaving them to consider erecting extra grandstands.
"We have experienced incredible demand for reserved grandstand seating tickets, and customers have quickly purchased our available inventory," said Julie Loignon, COTA's vice president of public and community relations, told ESPNF1.
"As such, we are considering installing more reserved seats between Turns 9 and 10 and between Turns 11 and 12 in place of other types of seating that had been planned for those areas.
"We will release more information about new grandstand inventory and when additional reserved seats might be available for purchase as soon as possible. We are extremely pleased with how things are going overall, since our public ticket sales began less than a week ago."
