Abstract In present work, spectrum of the S -wave fully-heavy tetraquark states $$QQ\bar{Q}\bar{Q}$$ Q Q Q ¯ Q ¯ ( $$Q=c,b$$ Q = c , b ), i.e., $$cc\bar{c}\bar{c}$$ c c c ¯ c ¯ , $$bb\bar{b}\bar{b}$$ b b b ¯ b ¯ , $$cc\bar{b}\bar{b}$$ c c b ¯ b ¯ / $$bb\bar{c}\bar{c}$$ b b c ¯ c ¯ , $$bc\bar{c}\bar{c}$$ b c c ¯ c ¯ / $$cc\bar{b}\bar{c}$$ c c b ¯ c ¯ , $$bb\bar{c}\bar{b}$$ b b c ¯ b ¯ / $$cb\bar{b}\bar{b}$$ c b b ¯ b ¯ , and $$bc\bar{b}\bar{c}$$ b c b ¯ c ¯ are systematically investigated within a nonrelativistic constituent quark model, in which the instanton-induced and one-
