The return of The Open to Portrush in July attracted record breaking numbers, making it the biggest ever sporting event staged here.
The figures represent a significant increase on the economic impact generated from the the last time The Open was held at Royal Portrush in 2019.
2025 figures are almost double those in 2019, and a growth of 67% in economic benefit for Causeway Coast and Glens.
The studies attributed this to an increase in attendance and spend by spectators, with more visitors staying in commercial accommodation.
More than half of attendees travelled to the Antrim coast from outside Northern Ireland, with almost 80% of those attending The Open for the first time.
