According to reports, Amazon is in early talks to sell Trainium, a line of custom ASICs, suggesting demand for custom AI chips is rising. Two leaders in this niche are Broadcom and Marvell Technology. Broadcom develops custom AI chips for partners including Alphabet, Meta Platforms, and OpenAI. In the second quarter of its fiscal year 2026, which ended on May 3, Broadcom's revenue increased 48% year over year to $22.2 billion, and its AI chip business posted sales of $10.8 billion, up 143% year over year. Broadcom's adjusted earnings per share increased 54% year over year to $2.44. Broadcom predicted an over 200% year-over-year increase in its AI chip business for Q3. The company's stock dropped after earnings. Alphabet has projected its capex spending will increase significantly in 2027 compared to this year's already massive $180 billion to $190 billion. Marvell Technology also develops custom AI chips for hyperscalers and has worked with both Amazon and Microsoft.
