Chaotic inflation predicts a large gravitational wave signal which can be tested by the upcoming Planck satellite. We discuss a supergravity implementation of chaotic inflation in the presence of moduli fields, and find that inflation does not work with a generic Kachru-Kallosh-Linde-Trivedi moduli stabilization potential. A viable model can be constructed with a fine-tuned moduli sector, but only for a very specific choice of Kaehler potential. Our analysis also shows that inflation models satisfying {partial_derivative}{sub i}W{sub inf}=0 for all inflation sector fields {phi}{sub i} can be combined successfully with a fine-tuned moduli sector.
