Omdia's latest "TV Design and Specification Market Tracker: Q2 2025 Forecast" projects that CastOS shipments in North America will surge from 6.5 million units in 2025 to 15 million by 2029.

Globally, Android will remain the leading platform, though its shipment share is expected to dip slightly from 42% in 2025 to 39% by 2029. However, since Android encompasses multiple variants (including China-specific versions), its consolidation impact is weaker than single-platform competitors. Tizen is projected to remain the second-largest TV OS, though its share will marginally decline from 17% to 16% over the same period.
Besides CastOS, the fastest-growing TV operating systems include Vidaa, whose market share is forecast to rise from 6% in 2025 to nearly 8% by 2029, and Amazon's Fire TV, which will grow from 4% to slightly over 5%.
Excluding China, Android (including Google TV) holds a 32% market share in 2025—lower than the global average but still dominant. Omdia's latest projections suggest expansion opportunities remain in the competitive OS market, particularly in Europe, where retailers and platform providers are closely monitoring North America's retailer-led consolidation strategies.
