Intel's modem chips will be in iPhones used on AT&T Inc's US network and some other versions of the smartphone for overseas markets, Bloomberg reported on Friday.
However, iPhones sold in China will use Qualcomm chips, and iPhones on Verizon Communications Inc's network will also stick with Qualcomm, Bloomberg added.
Qualcomm's shares fell 1.7 percent on Friday, while Intel's stock was up 0.3 percent. Apple shares were down 0.5 percent in morning trading.
On an earnings call in April, Qualcomm Chief Executive Officer Steve Mollenkopf said he was assuming that a major customer would switch to multiple suppliers.
An Intel spokeswoman declined to comment on the story. Qualcomm and Apple were not immediately available for comment.
