What Optimum does

Optimum is the primary consumer-facing brand of CSC Holdings, LLC, a wholly-owned subsidiary of Altice USA, Inc. (NYSE: ATUS), and operates a fiber-to-the-home broadband network across 14+ U.S. states including New York, New Jersey, Connecticut, Pennsylvania, Louisiana, Texas, California, Arizona, Arkansas, Idaho, Kansas, Kentucky, Mississippi, Missouri, and Nevada. The company is headquartered at 1 Court Square West, Long Island City, New York. Optimum unifies the consumer services previously marketed under the Altice and Suddenlink brands after a 2023 rebranding, and now sells Internet (300 Mbps to 8 Gbps fiber), Mobile (nationwide 5G), TV (Entertainment TV delivered via the Optimum Stream OTT device), and bundled service packages to residential households, small and medium businesses, enterprise customers, and government/low-income programs such as NYCHA's Big Apple Connect.

The core technology stack is a fiber-to-the-home network delivering symmetrical and asymmetrical speeds up to 8 Gbps, supplemented by Smart WiFi 6E gateways, Optimum Stream OTT devices, and legacy Optimum TV Box set-tops where Stream is not available. The company operates 125+ retail stores nationwide, dedicated consumer (877-694-9474) and business (800-819-1069) sales lines, self-serve portals for residential and business customers, and a separate enterprise portal (myfiberportal.com). Distribution is augmented by a referral/partner program targeting SMB acquisition. Customer acquisition is driven by competitor switching campaigns against AT&T and Verizon with contract buyouts up to $100 (consumer) and $1,500 (business), plus a five-year price lock guarantee on internet plans.

Revenue is generated primarily through recurring monthly subscriptions across Internet, TV, and Mobile tiers (e.g., 300 Mbps at $25/mo, 1 Gig at $45/mo, 8 Gig at promotional pricing; Entertainment TV at $30/mo; Unlimited Mobile at $45/line/mo), with incremental hardware/equipment rental fees, add-on services (Whole Home WiFi, Total Care, Premier Technical Support, Business Connection Backup), and a new transaction-fee stream from the Bango-powered Digital Vending Machine subscription management platform. Bundling Internet with TV and/or Mobile yields $5-$15/mo in savings. The network infrastructure represents a significant capital asset ($40M New Jersey FTTH deployment alone), and Optimum leverages third-party validation (Ookla Speedtest recognition as fastest and most reliable in NY/NJ, CNET recognition in Bridgeport and Stamford) and public-private partnerships (NYC Big Apple Connect, Empire State Development for 2026 FIFA World Cup viewing events) as competitive positioning tools.

Scale indicators7 records

Recent moves1 record

Expansion highlights7 records

Direct peers

• Verizon Fios: Verizon's fiber-to-the-home consumer and business broadband service is Optimum's most direct head-to-head competitor in the NY/NJ footprint, offering comparable gigabit tiers over FTTH and overlapping mobile/bundle offerings.
• Spectrum (Charter Communications): Charter's Spectrum brand is a national cable broadband and pay-TV competitor that directly overlaps Optimum's product portfolio (Internet, TV, Mobile, Business) in many of the same U.S. markets and jointly partners with Optimum in the Big Apple Connect NYCHA program.
• Xfinity (Comcast): Comcast's Xfinity is the largest U.S. cable broadband provider and offers the same converged Internet/TV/Mobile/home-security bundle that Optimum markets, competing on price, speed tiers, and bundled-mobile value in overlapping geographies.
• AT&T Internet / AT&T Fiber: AT&T's fiber and DSL broadband services compete directly with Optimum in residential and business segments; Optimum explicitly targets AT&T customers with switching incentives, indicating overlapping footprints and direct competition.
• Frontier Communications: Frontier is a fiber and copper broadband provider with meaningful overlap in the Northeast/Mid-Atlantic U.S. and is actively expanding FTTH passings, making it a direct Optimum competitor for both residential and enterprise fiber customers.
• WideOpenWest (WOW!): WOW! is a regional cable broadband, TV, and phone operator competing in similar Midwestern/Southeastern markets with comparable HFC-to-fiber upgrade economics; it's a relevant peer for benchmarking Optimum's mid-market cable strategy.
• Cox Communications: Cox is a privately held U.S. cable broadband, TV, mobile (via MVNO), and business services provider with a comparable converged-connectivity product set and similar capital-intensity profile in legacy HFC markets.

Emerging players

• T-Mobile Home Internet: T-Mobile's 5G fixed-wireless home internet product is an emerging alternative to Optimum's cable broadband in many of its markets, leveraging the nationwide 5G network to undercut cable on price and simplicity, though with lower top-end speeds.
• Starlink (SpaceX): SpaceX's Starlink satellite broadband service competes primarily in Optimum's rural and underserved cable-plant territories (Louisiana, Mississippi, parts of the Appalachians) where Optimum's fiber upgrades are most capital-intensive to deploy.
• Google Fiber: Google Fiber is a fiber overbuilder active in select U.S. cities; while not in most Optimum markets today, its expansion plans and 8 Gbps tier positioning set the competitive ceiling that Optimum's own 8 Gig product must match.
