When a streaming service signs a deal to carry a new catalog, the negotiation rarely stops at the content license. Behind the scenes, another set of costs looms: the fees paid to move that content across undersea cables. These interconnect fees, often invisible to subscribers, can determine whether a deal makes financial sense. As streaming giants expand globally, the economics of submarine cable networks have become a quiet arbiter of what you can watch, where you can watch it, and what you pay.

The Quiet Price Tag Behind Your Streaming Library

Streaming deals hinge on unseen fees. The headline numbers in a content licensing agreement cover the rights to stream a show or movie, but the delivery cost is a separate line item. Every bit of video that crosses an international border travels over a submarine cable, and the owner of that cable charges for the privilege. For a streaming service, those charges can add up to millions of dollars annually, especially for high-definition and 4K content, which consume far more bandwidth than standard video.

Undersea cables carry the traffic that makes streaming possible. The global backbone of the internet is a network of roughly 500 active submarine cables, laid across ocean floors and connecting continents. Each cable has a finite capacity, measured in terabytes per second, and that capacity is sold in the form of indefeasible rights of use (IRUs) or leased circuits. Streaming services buy capacity on these cables, either directly or through intermediaries, and the price per bit varies widely depending on the route and the volume of traffic.

Interconnect fees decide content availability. When a streaming service evaluates whether to launch in a new region, it looks at not just the local content rights but also the cost of delivering that content to local users. If the interconnect fees are too high, the service may choose to offer a reduced catalog, lower resolution, or no service at all. This is why some regions get a full library while others get a fraction, and why exclusive deals sometimes exclude entire countries.

Netflix and rivals negotiate quietly. The largest streaming platforms have dedicated teams that negotiate interconnect agreements with cable owners and internet service providers. These negotiations are confidential, and the terms are rarely disclosed. What is known is that the biggest players, like Netflix, Amazon, and Google, have enough traffic to demand favorable terms. Smaller services, with less leverage, often end up paying more per bit, which affects their ability to compete on price or content volume.

Cable owners hold the leverage. The companies that build and operate submarine cables control a strategic asset. Landing stations, where cables come ashore, are limited in number and often owned by the same consortiums that own the cables. This concentration gives cable owners significant pricing power. They can charge premium rates for routes with high demand, and they can make it difficult for new entrants to bypass their infrastructure. As a result, the economics of streaming are increasingly tied to the economics of the ocean floor.

Who Owns the Ocean Floor and Why It Matters

Submarine cable systems are private assets. Unlike roads or public utilities, undersea cables are built and owned by private companies, consortiums, or governments. The ownership structure varies: some cables are owned by a single company, others by a consortium of carriers, and some by tech giants like Meta or Google, which have invested heavily in their own cable systems to control costs and capacity.

Consortiums and tech giants invest heavily. A single submarine cable can cost hundreds of millions of dollars to build, and the investment is justified by the revenue from selling capacity. Tech giants have become major investors because their cloud and streaming services generate massive amounts of traffic. By owning cables, they can reduce their reliance on third-party providers and secure capacity at a lower cost per bit. This vertical integration gives them a competitive edge, but it also means that the largest players are effectively setting the terms for the rest of the industry.

Ownership shapes pricing power. When a cable is owned by a consortium of carriers, the pricing is often more predictable, as the owners are also the primary users. But when a single entity controls a cable, it can set prices more aggressively, especially on routes where there is little competition. This can lead to higher costs for streaming services that do not own their own infrastructure, and it can influence which deals get signed in regions served by a single cable system.

Landing stations are chokepoints. The physical points where cables come ashore are critical infrastructure. They are usually located in secure facilities, and access is restricted. Ownership of landing stations is often separate from cable ownership, but the two are closely linked. A cable owner may also own the landing station, or it may lease space from a third party. This creates additional layers of fees and gives those who control the landing stations a say in whether and how new cables can connect, further entrenching the incumbents.

Maintenance costs drive per-bit charges. Submarine cables are not maintenance-free. They are subject to damage from fishing trawlers, anchors, and even shark bites, and repairs require specialized ships and equipment. The cost of maintaining a cable system is significant, and it is factored into the price of capacity. For streaming services, this means that the price per bit is not just about the initial investment but also about the ongoing operational costs. As cables age and require more frequent repairs, the cost per bit can rise, putting upward pressure on streaming costs.

The Economics of a Single Gigabyte Abroad

Transit fees vary by route and volume. The cost of moving a gigabyte of data across an undersea cable is not uniform. It depends on the route, the distance, the capacity of the cable, and the volume of traffic. On heavily trafficked routes, such as transatlantic or transpacific, prices have fallen over the years due to competition and increased capacity. On less trafficked routes, such as those connecting island nations or landlocked regions, prices can be much higher, sometimes by an order of magnitude.

Peering agreements reduce costs. One way streaming services lower their interconnect costs is by entering into peering agreements with local ISPs. Peering allows two networks to exchange traffic directly, without going through a transit provider. When peering is settlement-free, neither party pays the other, which can significantly reduce costs. However, settlement-free peering is typically only available to networks of similar size and traffic volume. Smaller streaming services may not qualify, and they may have to pay for peering or rely on transit, which is more expensive.

Settlement-free vs. paid peering. The distinction between settlement-free and paid peering is crucial. In settlement-free peering, both parties benefit from the exchange, so no money changes hands. In paid peering, one party pays the other, usually because the traffic flow is uneven. Streaming services, which send far more data to users than they receive, often find themselves on the paying end of peering agreements. This is where interconnect fees become a significant cost, and it is why some streaming services have fought for regulations that would limit the ability of ISPs to charge them for peering.

Content delivery networks bypass fees. To avoid paying high transit and peering fees, streaming services use content delivery networks (CDNs). A CDN caches content at servers located close to users, so that most traffic never crosses an undersea cable. This reduces the amount of intercontinental traffic and, with it, the associated fees. However, CDNs are not a complete solution. The first time a user requests a piece of content, or when the CDN cache is refreshed, the content must be fetched from the origin server, which may be on another continent. This origin traffic still crosses cables and incurs fees.

Smaller providers feel the squeeze. The combination of transit fees, peering costs, and CDN expenses can be prohibitive for smaller streaming services. They may not have the volume to negotiate favorable rates, and they may not have the technical expertise to optimize their delivery architecture. As a result, they often face higher per-gigabyte costs, which eats into their margins. This can lead to higher subscription prices or a smaller content library, making it harder for them to compete with the big players.

How Streaming Giants Reroute the Map

CDNs cache content closer to users. The primary tool that streaming giants use to manage interconnect costs is the CDN. By deploying servers in multiple regions, they can serve content from a local cache, reducing the need to send traffic across undersea cables. This not only lowers costs but also improves performance, as users experience lower latency and faster start times. For popular content, the cache hit rate can be very high, meaning that most streams are served locally.

Local servers cut intercontinental traffic. When a CDN has a presence in a region, the majority of traffic is handled locally. This is why streaming services invest heavily in building out CDN nodes in emerging markets, even if the local user base is small. The savings on interconnect fees can be substantial, especially in regions where transit costs are high. However, the decision to deploy a CDN node is not always straightforward. It requires capital investment and ongoing operational costs, and the payoff depends on the volume of traffic that the node can attract.

But origin traffic still crosses cables. Even with a robust CDN, there is always some traffic that must cross oceans. New content, updates to the catalog, and uncached requests all require fetching data from the origin server. The origin server is often located in the home country of the streaming service, which means that intercontinental traffic is inevitable. This is where the interconnect fees still apply, and it is why streaming services are careful about where they place their origin servers and how they manage their content distribution.

Licensing deals often mandate delivery. Another factor that influences the economics of interconnect fees is content licensing. Some licensing agreements specify that content must be delivered from a particular location or through a particular network. This can be a way for the licensor to maintain control over the distribution, but it can also force the streaming service to use expensive routes. In some cases, the licensor may require that the content be delivered via a specific CDN, which may not be the most cost-effective option for the streaming service. These contractual requirements can add to the cost of a deal and may even make it uneconomical.

Geography dictates negotiation leverage. The physical location of a streaming service's customers and its origin servers plays a significant role in its negotiation power. If a service has a large user base in a region, it can negotiate better rates with cable owners and ISPs. Conversely, if a service is trying to enter a new market with a small user base, it has less leverage and may have to accept higher interconnect costs. This is why some streaming services choose to launch in a few large markets first, where they can build up volume and negotiate better terms before expanding to smaller regions.

The Regulators' Slow Dance with Cable Economics

Open internet rules touch interconnection. The debate over net neutrality has often focused on the relationship between ISPs and content providers, and interconnection is a key part of that. In jurisdictions with strong open internet rules, such as the European Union, regulators have sometimes stepped in to ensure that interconnection agreements are fair and that ISPs do not abuse their market power. This can provide some protection for streaming services, but the rules are not always clear-cut, and enforcement can be slow.

Net neutrality debates linger globally. In the United States, the status of net neutrality has fluctuated with changes in administration. Some states have enacted their own rules, creating a patchwork of regulations. Elsewhere, countries like India and Brazil have implemented strong net neutrality principles, while others have taken a more hands-off approach. This inconsistency makes it difficult for streaming services to plan their global expansion, as they must navigate a complex web of regulations that affect how they can negotiate interconnect agreements.

Some regulators mandate fair terms. In a few countries, regulators have gone beyond general net neutrality rules to specifically address interconnection. For example, in South Korea, the government has intervened in disputes between content providers and ISPs over network usage fees. These interventions can force ISPs to accept settlement-free peering or to lower their transit prices, which benefits streaming services. However, such mandates are the exception rather than the rule, and they can be controversial, as they may be seen as government interference in private contracts.

Others let private contracts rule. In many regions, regulators take a laissez-faire approach, allowing cable owners and streaming services to negotiate their own terms. This can lead to a wide range of prices and conditions, reflecting the relative bargaining power of the parties. While this flexibility can be beneficial, it can also result in higher costs for smaller players and less transparency for consumers. The lack of regulatory oversight means that interconnect fees can remain a hidden cost, buried in the operating expenses of streaming services.

Recent rulings hint at change. There have been some recent developments that could reshape the regulatory landscape. For example, in the European Union, the European Electronic Communications Code includes provisions on open internet and has been interpreted to apply to interconnection. Some national regulators have started to examine whether certain ISPs are abusing their position in the interconnection market. While no major rulings have been handed down yet, the direction suggests that regulators are becoming more willing to scrutinize the economics of undersea cables and interconnect fees.

What This Means for Your Next Streaming Subscription

Expect regional price differences. As interconnect fees vary by region, streaming services are likely to pass some of these costs on to consumers. In areas where transit costs are high, subscription prices may be higher, or the service may offer a lower tier with reduced quality. Conversely, in regions where interconnect fees are low, consumers may benefit from lower prices or higher-quality streams. This is already visible in some markets, where streaming services charge different prices for the same content based on geography.

Exclusive deals may reflect cable costs. When a streaming service signs an exclusive deal for a popular show, the cost of delivering that show to a global audience is a factor in the deal's economics. In regions where interconnect fees are high, the service may choose not to offer the show, or it may offer it only in lower resolution. This can lead to a situation where a show is available in one country but not in another, not because of licensing restrictions but because of the cost of delivery. As a result, the content you see in your library may be influenced by the undersea cable capacity in your region.

New entrants might avoid costly regions. For new streaming services, the cost of entering a market with high interconnect fees can be prohibitive. They may decide to skip certain regions altogether, focusing instead on markets where they can deliver content more affordably. This can limit consumer choice and create a divide between regions with a wide selection of streaming options and those with fewer. It also means that the growth of streaming services is not uniform, and the economics of undersea cables play a role in shaping the competitive landscape.

Bundles could mask interconnect fees. To manage interconnect costs, some streaming services may bundle their offerings with other services, such as internet access or mobile plans. This can obscure the true cost of content delivery, as the interconnect fees are folded into a broader subscription package. For consumers, this may mean that they are paying for content delivery without realizing it, but it could also lead to more affordable overall packages. However, it also means that the price of a streaming service may not be directly comparable across providers, as some may be cross-subsidizing their content delivery costs through other revenue streams.

Watch for shifts in content availability. As the economics of undersea cables evolve, so too will the way streaming services make decisions about content availability. If interconnect fees rise, you may see fewer exclusive deals in certain regions, or a move toward more locally-produced content that can be delivered without crossing oceans. Alternatively, if fees fall due to increased capacity or regulatory intervention, you may see a broader selection of content at lower prices. The key is to be aware that the content you see is not just a result of creative decisions but also of the complex economics of the infrastructure that delivers it.
