Alkyne also known as acetylene has formula C2H2 or H-C≡C-H and carbon C atom in it is sp hybridized that's why C atom is more electronegative than in Alkanes or Alkenes hydrocarbons. And so this electronegativity makes hydrogen H atom behave like acidic hydrogen.

In Acetylene, both the carbon atom undergoes SP hybridization, so each carbon gives two Sp hybrid orbitals.
Sp hybrid orbitals contain 50% S orbital character . As S - character increases the electronegativity of carbon increases which makes -C-H bond highly acidic in nature.
We can justify the acidic character of Acetylene by following chemical reaction:
Sodium metal when reacts with acetylene results in hydrogen getting displaces from acetylene and forming Sodium acetylide.
CH ≡CH +Na-----> HC ≡CNa +1/2H2
