Strategically, Nvidia’s ecosystem dominance pressures AMD and Marvell to accelerate differentiated IP; Intel may leverage this to push its IDM 2.0 model with North American clients. Over the next 12–24 months, only firms with real AI monetization—like Broadcom’s custom TPUs or ARM’s Neoverse licensing—will survive valuation mean reversion.
