Slater revealed the news with an Instagram post, before the Kelly Slater Wave Company posted the same video to their Facebook account.
The World Surf League reports the video had more than 250,000 views in the first hour it was uploaded.
Slater described the success his team has had as a dream come true.
"Now that the world title has been decided and events for the year have finished, I'm excited to show you what I've been sitting on for the past couple of weeks," he posted on Instagram.
"For nearly ten years, my team and I have been working on creating the first truly world-class, high-performance, human-made waves.
"This is something I dreamt about as a kid. Through rigorous science and technology, we've been able to design and build what some said was impossible, and many very understandably never thought would actually happen.
"I'm proud to say we took our time to get it right, and the first fully-working prototype of the wave now exists (a huge personal thank you to everyone in our lab and on our team for seeing this through!).
"I'll be sharing more details in the coming weeks and months but I can't wait any longer to share a film of my experience surfing the wave for the first time, almost two weeks ago.
"It was an insane day. I'm still a little in disbelief, and trying to process how much fun this wave is, but it certainly feels like this is going to change a lot of perceptions about human-made waves.
"There's a direct link in my bio to kswaveco.com to view the short film. Can't wait to see other people surf it soon and show what is possible on this thing. #KSWaveCo #FreakOfTechnology #LooksLikeSuperbank but #NotCrowded."
The World Surf League said Slater's team has been working on the wave at a secret test facility more than 170km inland from the nearest beach.
Surfing fans described the first views of the break as Slater's greatest gift to the sport yet.
