The most cost efficient option is antenna + subscribing to Peacock. That will get you all the big Fox games over the air, and any others will be on Telemundo (albeit in Spanish) on Peacock. Other considerations: - It looks like 21 group stage games are on big Fox with the other 27 on FS1, and all the US group games are on Fox. - The Cable games are slanted towards the weekends, presumably since Fox has football obligations that take precedence. - All of the knockout games are on big Fox except the 2 round of 16 games on Sunday December 4th(again, presumably because of NFL obligations) - Unfortunately, if the US wins their group, they'll be one of those December 4th games TL;DR if you have a way to watch Fox OTA you're gonna be able to watch a lot of these games. The cheapest option to fill in the cable gaps is Peacock, but it'll be in Spanish.
