The answer to this question depends on how you define "owns" and "world records."
If you're asking about individuals who hold the most world records, then the answer is Ashrita Furman. He holds over 700 Guinness World Records, earning him the title of "World Record Holder" in a variety of categories, including:
- Longest time balancing a tennis racket on the nose: 31 hours, 28 minutes, and 15 seconds
- Longest time balancing a spoon on the nose: 2 hours, 13 minutes, and 52 seconds
- Longest time balancing a broom on the nose: 1 hour, 20 minutes, and 41 seconds
However, if you're asking about organizations that hold the most world records, then the answer is Guinness World Records. They are the official authority on record-breaking achievements and have certified millions of world records across various categories.
While individuals and organizations may hold numerous world records, it's important to note that the Guinness World Records organization ultimately owns the rights to all the records they certify.
