OpenAI Launches Jalapeño Chip, Promises Faster, Cheaper AI

6/24/2026

Summary

OpenAI Unveils Chip

OpenAI unveiled its first custom AI chip, Jalapeño, developed with Broadcom.
President Greg Brockman said Jalapeño aims to make AI compute more efficient and cheaper.
Early tests show Jalapeño outperforms state-of-the-art processors and offers better performance-per-watt for inference.
OpenAI built the chip in nine months as the first step toward a roadmap targeting 10 GW of computing and is preparing a trillion-dollar IPO after spending billions on Nvidia GPUs.

Summary

Broadcom Backs OpenAI

Broadcom formed a financing vehicle with Apollo Global Management and Blackstone to fund OpenAI’s Jalapeño chips.
OpenAI raised $122 billion this year to support data-center expansion and chip purchases.
Broadcom shares rose 1.6% to $386.25 and are up nearly 10% YTD after the chip reveal.
Bloomberg says OpenAI plans to spend tens of billions on Broadcom chips, adding to multibillion-dollar deals with AMD and Cerebras that diversify away from Nvidia.

Summary

Microsoft Secures Chips

Prototype Jalapeño chips will be deployed by late 2026, with production ramping in 2027-2028.
Microsoft will purchase about 40 % of the initial chip output for gigawatt-scale data centers.
OpenAI’s models accelerated the ASIC design, creating a software-hardware feedback loop.
Gigawatt-scale deployment will consume power comparable to a city, raising energy concerns.

Summary

Broadcom Margin Squeeze

Broadcom's profit margin on custom AI chips is lower than on its networking-switch products.
The chips require large amounts of high-bandwidth memory, which intensifies margin pressure.
SK Hynix and Samsung Electronics supply memory chips for Broadcom's Jalapeño processor.
Broadcom's shares have risen almost sevenfold since the end of 2022 and are up 10% in 2026.
The company serves six AI customers whose compute demand is described as “simply insatiable” through 2028.

History

Historical Context

Google began building custom AI silicon in 2013, and in May 2016 unveiled the first Tensor Processing Unit, which Norman Jouppi’s team showed delivered 15–30 times higher performance and up to 80 times better performance-per-watt than contemporary CPUs and GPUs. OpenAI’s 2024 Jalapeño chip project, financed by Broadcom, Microsoft and others, mirrors this shift toward proprietary accelerators reshaping data-center hardware.
