I think Nvidia (NVDA +0.63%) will be an excellent stock to own in 2026. So, investors need some alternative AI stocks to diversify a bit in the artificial intelligence (AI) space. Three stocks that I think can make for strong alternative investments to Nvidia are Taiwan Semiconductor (TSM 0.87%), Broadcom (AVGO 0.65%), and AMD (AMD 0.24%). In the fourth quarter, AI semiconductor revenue was $6.5 billion, up 74% year over year. For Q1, they expect $8.2 billion in AI semiconductor revenue, up 100% year over year.
