The present disclosure relates to a thermoplastic resin having excellent non-whitening properties, impact strength, gloss, and fluidity, and a method of preparing the thermoplastic resin. The thermoplastic resin includes an alkyl acrylate-alkyl methacrylate graft copolymer (A), or the copolymer (A) and a matrix resin (B) including one or more selected from the group consisting of an aromatic vinyl compound-vinyl cyanide compound-alkyl methacrylate copolymer and an alkyl methacrylate polymer. A transparency measured under a condition of 3 mm thickness is less than 5, the total content of the alkyl acrylate is 20 to 50% by weight, and an alkyl acrylate coverage value (X) as calculated by Equation 1 below is 65 or more:={()/}×100,  [Equation 1]
