Can anyone claim to own a digit of pi?

No. A single digit is a fact, not a creation. Copyright protects expression, not mathematical facts — you can own a poem about π, but not its millionth digit.12

Details

What the law says

Copyright requires human creative expression. Every digit of π is discovered, not authored — anyone can recompute the same result — so there's nothing protectable to claim.2

The things that look like ownership

"Adopt a digit of π" offers are commemorative certificates, about as binding as naming a star: you get a piece of paper, and the mathematics doesn't move an inch.2
