The rumor of Sprint (NYSE:S) and T-Mobile (NASDAQ:TMUS) potentially merging began in 2013 when SoftBank (OTCPK:SFTBY) first gained control of S. The merger talks fell apart in 2014 when the FCC, under Obama, killed the deal from progressing any further. However, it is not 2013 anymore, times have changed and it is now more likely than ever that TMUS and S will merge.
The FCC also recently lifted a rule barring telecom companies from talking to each other about potential merger deals. This rule was put in place because of a nationwide low band spectrum auction deal, which took place from 2016. Now that the ban is lifted and the FCC is much more business-friendly under Trump, the chances of some sort of merger happening between Sprint and T-Mobile are higher than ever.
