The streaming wars are no longer just about who can sign up the most subscribers. In 2025, the battlefield has shifted to profitability, advertising, live events and clever bundling. Netflix still wears the global crown, but in both the US and the UK, competition has become far more complex. With broadcasters reinventing themselves and new ad-supported tiers reshaping viewing habits, the fight for dominance has never been fiercer.

The US Picture: Scale, Ads and Prime's Secret Weapon

Netflix Still Leads Consumption. Netflix continues to dominate the US market, boasting more than 80 million American subscribers and over 300 million worldwide. It remains the largest single streaming marketplace in the country

Amazon Prime's Built-In Advantage. Prime Video rides on the back of Amazon Prime's vast US membership base, estimated at around 170–180 million. That means Prime Video benefits not only from streaming content but also from Amazon's powerful retail bundling.

Streaming Surpasses TV. In May 2025, streaming hit a historic milestone, accounting for 44.8% of all US television viewing — eclipsing broadcast and cable combined. This shift solidifies streaming as America's primary source of entertainment.

Ad-Tiers on the Rise. Low-cost, ad-supported plans are booming, with analysts predicting rapid growth in free ad-supported streaming TV (FAST) throughout 2025. Viewers gain cheaper access to content while platforms cash in on advertising.

The UK Picture: Netflix on Top but Broadcasters Fight Back

Netflix Holds the Crown. Around 17–18 million UK households subscribe to Netflix, making it Britain's most popular paid streaming service. Amazon Prime Video, BBC iPlayer, ITVX and Sky's offerings trail close behind.

Sky's Transformation Battle. Sky, part of Comcast, is restructuring as it pivots from pay-TV towards streaming, investing in Sky Stream and Sky Glass while cutting jobs to stay competitive.

Broadcasters Refuse to Fade. Unlike in the US, the UK retains strong loyalty to public broadcasters. BBC iPlayer and ITVX continue to pull in millions, with sports and live events keeping them firmly in the game.

Shared Trends Across the Atlantic

Profit Over Pure Growth. Streamers are shifting focus from expansion to profitability — cracking down on password sharing, trimming budgets and leaning heavily into ad revenues.

Sporting Rights Are the New Gold. Exclusive sports deals are becoming the ultimate differentiator. The platforms that lock down live rights will hold the key to retention.

Local Content Still Matters. From British drama to American blockbusters, platforms that cater to local tastes — while striking clever bundling deals with telcos and retailers — are best placed to weather churn.

Quick Reference: 2025 in Numbers

  • US: Netflix — ~81m subscribers; Amazon Prime membership — ~170–180m; streaming accounts for 44.8% of TV viewing.
  • UK: Netflix — ~17–18m households; Sky actively restructuring; BBC iPlayer and ITVX remain major players.

Conclusion — Winners Without a Crown

The streaming wars in 2025 aren't about crowning a single victor but about adapting to a new era. In the US, Amazon and Netflix are locked in a battle of scale versus bundling, while in the UK, broadcasters and Sky refuse to cede ground to the American giants. The message is clear: the platforms that balance value, local relevance and smart monetisation will define the next chapter — and viewers on both sides of the Atlantic will be the ones calling the shots.
