Nvidia Put $2 Billion Into Coherent. Is Optical Bandwidth the Next AI Bottleneck?

Nvidia has invested $2 billion in Coherent Corp. and formed a strategic partnership covering optics development and access to manufacturing capacity. This investment aligns with the need for faster and more efficient data connections as AI clusters grow larger. The arrangement gives Nvidia a critical input before demand peaks, while Coherent gains capital, demand visibility, and validation from the AI industry's leading platform.

However, scaling production and managing customer concentration, manufacturing yields, pricing negotiations, and technology transitions remain key factors in determining whether this investment proves attractive. The non-exclusive structure allows both companies to maintain alternative suppliers and sell beyond Nvidia, making the partnership more resilient than a potential acquisition.

The strong thesis lies in the fact that AI architectures require more optical content, benefiting both partners if execution holds. However, short-sellers have increased their positions in Coherent, indicating uncertainty about the long-term viability of this investment.
