Is Vox a 501c3?

Excuse me, could you please clarify if Vox is classified as a 501(c)(3) organization? As I understand, 501(c)(3) is a tax-exempt status granted to charitable organizations in the United States. I'm curious if Vox, as a media platform, fits into this category or if it operates under a different legal structure. I would greatly appreciate it if you could provide some insight into this matter. Thank you in advance for your response.
