How this fits the existing thesis

Parent thesis: Broadcom's custom AI ASIC business is growing faster than almost anyone expected, positioning it as the primary alternative to Nvidia for hyperscaler AI compute — yet the stock has sold off 23% from its high as investors demand clearer proof of sustained growth. AMD co-led a $350 million funding round in TensorWave, an AI cloud provider built exclusively on AMD hardware, signaling that AMD is actively seeding an alternative GPU ecosystem to challenge Nvidia's dominance. Together, Broadcom and AMD represent the emerging challenger layer in AI silicon, distinct from Nvidia's GPU monopoly narrative already covered in the AI infrastructure thesis.
