According to @trillionspod, European Defense ETFs have rapidly grown from near obscurity to $11 billion in assets under management in 2024, equivalent to $60 billion in the US market. This explosive growth was discussed on the latest Trillions episode, highlighting how a few early entrants captured most inflows, while new competitors are now entering the space (source: Trillions podcast with @ETFhearsay). For crypto traders, this trend signals a shift in investor appetite toward defense and security sectors, potentially impacting capital allocation and risk sentiment in global markets. Monitoring ETF flows can help anticipate volatility and sector rotation that may spill over into crypto trading volumes.
