We list all potential candidates for U(1) anomalous non-local 1-loop 4-pointamplitudes and higher loop UV divergences in $\mathcal{N}\geq 5$supergravities. The relevant chiral superinvariants are constructed fromlinearized chiral superfields and define the corresponding superamplitudes. Theanomalous amplitudes, of the kind present in $\mathcal{N}=4$, are shown to beabsent in $\mathcal{N} \geq 5$. In $\mathcal{N}=6$ supergravity the result isdeduced from the double-copy $\mathcal{N}=4_{YM} \times (\mathcal{N}=2)_{YM}$model, whereas in $\mathcal{N}=5,8$ the result on absence of anomalousamplitudes is derived in supergravities as well as in the $(\mathcal{N}=4)_{YM}\times (\mathcal{N}-4)_{YM}$ double-copy models.
