So, the other day I was just kicking back, scrolling through some fight highlights online, you know how it goes. And this clip pops up – a UFC fight ending almost instantly. Like, bam, lights out. It really caught my eye. I thought, man, that was ridiculously fast. It got me curious, like, what are the actual record-breaking quick knockouts in the UFC?

Down the Rabbit Hole
My curiosity totally took over. So, I decided to look into it myself. Nothing too serious, just me wanting to see these quick finishes. I sat down at my desk, fired up the old computer, and typed ‘ufc quickest ko’ into the search bar. Simple as that.
Let me tell you, I probably spent a good hour or more just clicking through videos and reading little blurbs about different fights. Of course, the first one that kept showing up was that Jorge Masvidal flying knee on Ben Askren. Five seconds? Something insane like that. You see it once, you don’t forget it.
But it wasn’t just that one. I started finding lists and more clips:
- There were some older fights I hadn’t even heard of, ending super quick.
- I saw that one by Duane Ludwig, just a flash of a punch.
- Then there was that Korean Zombie knockout, a few punches and done.
- Even some Ronda Rousey finishes, armbars locked in before the opponent knew what hit ’em.
It was pretty cool seeing the variety. Head kicks, knees, punches… all happening in under 10, sometimes under 5 seconds. I wasn’t trying to break down the technique like a pro or anything. I was just watching, kind of amazed at the speed and suddenness of it all. How one perfect shot could just end everything right then and there.
My Takeaway
After watching a bunch of these super-fast KOs, the main thing I walked away with was just a real appreciation for the fighters. It’s not just about being strong or tough. It’s about timing, precision, and seeing that split-second opening. It takes incredible skill to do that. Made me realize how unpredictable those fights can be. All that training, all the hype, and sometimes it’s over before you can even blink. Just wild.
