Corporate giants are making big contributions to disaster relief organizations to help victims of Tropical Storm Harvey.
Companies have pledged $26 million to relief efforts as of Tuesday morning, according to an estimate from the U.S. Chamber of Commerce. But this figure is constantly changing as contributions continue to pour in.
CNNMoney's analysis found companies had pledged nearly $40.9 million by late Tuesday afternoon, and 23 companies have donated $1 million or more. Verizon alone contributed $10 million on Tuesday.
Meanwhile, employee donation matching programs announced so far could bring in an additional $3.3 million. This figure will likely climb, as some companies left the amount they would match open ended, while others are also accepting customer donations.
