The direct production of J/ψ(ψ′) at large transverse momentum, p<sub>T</sub> ≫ M<sub>J/ψ</sub>, at the Fermilab Tevatron is revisited. It is found that the sea-quark initiated processes dominate in the high-p<sub>T</sub> region within the framework of colour-singlet model, which is not widely realized. This finding is enlightening for further investigation on the charmonium production mechanism.
