Key Findings
8 internet providers available in Silverthorne, CO
Fiber internet available from 3 providers
Silverthorne is a small CO community of 4,402 residents where wired broadband options are limited. Most households rely on a single cable or DSL provider, with satellite internet (Starlink, HughesNet) and fixed wireless serving areas beyond the wired footprint. Federal BEAD funding may bring fiber infrastructure to communities like Silverthorne, though deployment timelines depend on state-level grant awards. At a median household income of $66,817, value-oriented broadband plans are popular among Silverthorne households. Mid-range plans offering 200-500 Mbps at $40-$70/month represent the sweet spot for most families in this income tier, balancing speed needs with monthly budget. Silverthorne's housing stock is predominantly single-family homes, which gives homeowners the freedom to choose from any available ISP without building-level contracts or restrictions. This housing type also allows installation of outdoor equipment like satellite dishes and fixed wireless antennas, broadening the range of available internet options.
Silverthorne, CO is exceptionally well-served with 8 broadband providers, creating strong competition that drives down prices and incentivizes faster speeds and better service.
Silverthorne, CO has a highly concentrated broadband market (HHI: 45,774) where Viasat dominates with 100% coverage reach — 0 percentage points ahead of the next-largest provider, HughesNet at 100%. In highly concentrated markets, consumers typically see fewer promotional offers and less pressure on the leading provider to invest in network upgrades. The remaining 6 providers in Silverthorne, CO cover a fraction of addresses, limiting their competitive impact. Research from the FCC shows that markets with one dominant provider average higher monthly costs compared to markets with two or more meaningfully overlapping competitors. Fiber internet is available from 3 providers (Xfinity, CenturyLink, AT&T Internet), with 84% fiber coverage — significantly above the national average of 57%. Fiber delivers symmetrical upload and download speeds — a key advantage for households with multiple remote workers, video conference participants, or content creators who upload large files. Nationally, fiber represents the fastest-growing broadband technology segment, expanding at roughly 8 percentage points of coverage per year. Xfinity provides the primary cable broadband alternative with 84% coverage — above-average cable coverage of 72%. Cable internet uses DOCSIS 3.1 technology to deliver download speeds of 100 Mbps to 1.2 Gbps, though upload speeds (typically 10-35 Mbps) lag behind fiber's symmetrical performance. For households that do not require heavy upstream bandwidth, cable plans often offer competitive pricing to fiber. Fixed wireless internet — including 5G home internet services — is available from T-Mobile and AT&T Internet, reaching 47% of addresses (well above the national fixed wireless average of 32%). Fixed wireless offers a no-installation alternative that is increasingly competitive with cable for everyday internet use, with speeds typically ranging from 50-300 Mbps download. Unlike satellite, fixed wireless delivers lower latency (20-40 ms), making it viable for video conferencing and gaming. Satellite internet (Viasat, HughesNet, Starlink) reaches addresses that wired broadband can't. Starlink's low-Earth-orbit (LEO) technology delivers 20-60 ms latency — a major improvement over geostationary services at 600+ ms — making it a practical choice for rural households without fixed-line options.
Fiber-optic internet is available to only 0% of addresses in Silverthorne, CO — 57 percentage points below the national average of 57%. This significant gap reflects underinvestment in fiber infrastructure relative to the national buildout pace. Households without fiber access should evaluate cable, fixed wireless, or satellite alternatives while monitoring whether BEAD-funded fiber expansion is planned for this area. Cable broadband reaches 96% of addresses — 24 points above the national cable average of 72%. Strong cable coverage ensures most households have access to speeds of 100 Mbps or higher, making cable a reliable fallback even where fiber has not yet arrived. Fixed wireless internet — including 5G home internet from T-Mobile and Verizon — covers 93% of addresses, 61 points above the national fixed wireless average of 32%. Higher-than-average wireless availability gives residents an additional competitive alternative that can keep wired ISP pricing in check. This area has minimal fiber infrastructure. Fixed wireless (5G/LTE) and satellite (Starlink) may offer better near-term alternatives while fiber buildout gradually expands to underserved markets.
Colorado received $826 million in federal BEAD funding. The Colorado Broadband Office is currently in the challenge phase, which means providers and communities can dispute the FCC broadband maps that determine which locations qualify for funding — a critical step before deployment grants are awarded. The Affordable Connectivity Program (ACP) previously provided up to $30/month subsidies for eligible households, though federal funding expired in 2024. Some providers continue offering voluntary low-income discounts.
