The great convergence: the state of US wireless competition

US wireless service has settled into a tight three-way contest among AT&T, Verizon and T-Mobile, but the real disruption is coming from cable companies. Even after the Sprint–T-Mobile merger cut the number of national wireless carriers, the market has not relaxed. Instead, all three big operators now fight over subscribers on razor-thin margins, using discounts, bundled services and promotions to keep churn low and growth moving.

Cable operators that resell mobile service over these same networks have quietly become major players. By 2025, they accounted for 45% of all new wireless customer additions, pulling in price-sensitive users with lower-cost plans tied to broadband or TV. The result is a converged market where traditional wireless carriers and cable providers sell similar mobile products on many of the same underlying networks, leaving little room for easy profit and keeping competitive pressure high across the sector.
