Defiance ETFs launched the Defiance Global Foundries ETF (Nasdaq: AIFR), which it identifies as the first U.S.-listed ETF dedicated to semiconductor foundries. The fund targets the manufacturing layer of artificial-intelligence infrastructure, including companies that fabricate AI accelerators, custom silicon, networking chips, power-management components and other semiconductors. Taiwan Semiconductor Manufacturing Company held roughly 72% of global foundry revenue in the first quarter of 2026, according to TrendForce, while the 10 largest foundries generated a record $169.5 billion in 2025 revenue and set another quarterly record in the first quarter of 2026. AIFR seeks to track the MarketVector Global Foundries Index, which selects 10 publicly listed companies globally, including pure-play foundries and diversified semiconductor companies with economically significant foundry operations. The index spans issuers in Taiwan, South Korea, the United States, Israel and Hong Kong, and caps each constituent at 20% at rebalance. The fund normally invests at least 80% of net assets in index-related securities, depositary receipts and derivatives, and may invest up to 15% in private foundry companies. It charges a 0.71% expense ratio, trades on Nasdaq and is advised by Tidal Investments LLC. The fund is concentrated and non-diversified, carries foreign-market, currency, semiconductor, derivatives, private-company and other risks, and offers no guarantee of returns or principal protection.
