Thematic Alpha Generation: The Five Converging Platforms

ARK Invest's 2025 investment thesis is anchored in five key innovation platforms: Artificial Intelligence (AI), Public Blockchains, Autonomous Mobility, Energy Storage, and Multiomic Sequencing. According to the firm's Big Ideas 2025 report, these platforms are expected to drive exponential growth, with disruptive innovation projected to command over two-thirds of the global equity market by 2030, compounding at a 38% annual rateARK Invest Unveils its ‘Big Ideas 2025’ Report^[1].

The Reaccelerating Tech Cycle: A Catalyst for Alpha

Risks and Opportunities in the Thematic Framework

While ARK's strategy has generated compelling returns, it remains subject to market volatility and sector-specific risks.
