Nvidia has licensed technology from Groq, a hardware-focused company, in a deal worth $20B, avoiding a full acquisition and potential regulatory scrutiny. This move allows Nvidia to acquire Groq's talent and intellectual property without taking on the company's existing contracts and liabilities. The deal has sparked discussion about the implications for the startup scene and the treatment of employees in such transactions. The structure of the deal has also raised questions about regulatory arbitrage and the role of investors.
