Analysis
The elevation of Coherent Corp. (COHR) and Lumentum Holdings (LITE) to the S&P 500 marks a significant shift in the artificial intelligence investment landscape, moving from a focus on pure-play chipmakers to the essential 'picks and shovels' of data center connectivity. Nvidia, which has reportedly committed billions in purchase orders and strategic R&D partnerships to these entities, has effectively acted as a kingmaker. As Nvidia scales its Blackwell and future-generation GPU architectures, the bottleneck has shifted from raw compute power to the speed at which data can move between chips. This is where Coherent and Lumentum, leaders in optical transceivers and laser technology, have become indispensable.
For the venture capital and startup ecosystem, this development validates a broader 'AI Infrastructure' thesis. While much of the early-stage funding in 2024 and 2025 focused on Large Language Models (LLMs) and application layers, the inclusion of COHR and LITE in the S&P 500 demonstrates that the most sustainable value is currently being captured by companies solving physical constraints in the data center. Coherent’s leadership in 800G and 1.6T optical transceivers is a direct response to Nvidia’s demand for higher bandwidth, while Lumentum’s photonics expertise is critical for the low-latency networking required for massive AI training clusters. The market is now pricing in the reality that an AI chip is only as good as the network it sits on.
(COHR) and Lumentum Holdings (LITE) to the S&P 500 marks a significant shift in the artificial intelligence investment landscape, moving from a focus on pure-play chipmakers to the essential 'picks and shovels' of data center connectivity.
The short-term consequences of this S&P 500 inclusion are primarily driven by passive investment flows. Trillions of dollars in index-tracking funds will now be required to purchase shares of COHR and LITE, providing a massive liquidity injection and likely driving a valuation re-rating. However, the long-term implication is more strategic: Nvidia is effectively verticalizing its supply chain through deep financial and technical integration. By 'investing billions'—whether through direct equity, prepayments, or guaranteed purchase agreements—Nvidia ensures that its competitors face a supply-constrained market for the most advanced optical components.
What to Watch
Industry analysts suggest that investors should now look toward the next frontier of this infrastructure play: silicon photonics and liquid cooling. As power density in AI racks continues to climb, the companies that Nvidia 'blesses' with strategic partnerships will likely follow a similar trajectory to Coherent and Lumentum. The 'Nvidia Effect' is no longer limited to its own stock price; it is now a primary driver of index composition and sector-wide capital allocation. For startups, the message is clear: alignment with Nvidia’s hardware roadmap is the fastest path to institutional scale.
Looking ahead, the primary risk for these new S&P 500 entrants is their high concentration of revenue from a single customer. While Nvidia’s growth shows no signs of slowing, any pivot in Nvidia’s networking strategy—such as a move toward proprietary in-house optical solutions—could create significant volatility. Nevertheless, for the current cycle, Coherent and Lumentum represent the essential physical layer of the AI revolution, and their inclusion in the benchmark index is a formal recognition of the hardware-heavy reality of the digital future.

How we covered this story
Every story in our startup coverage is assembled from multiple primary sources, cross-referenced for factual consistency, and scored along three independent dimensions: sentiment, operational impact, and source-cluster confidence. Single-source rumors and unverifiable claims do not pass our editorial gate. When a story shows "Verified by N sources" with N≥2, the development is independently corroborated; when N=1, we mark it explicitly so readers can weigh the signal accordingly.
Impact scoring uses a 1-10 scale weighted toward regulatory, financial, and operational consequence rather than coverage volume. A topic that runs in every outlet but moves no real decisions ranks lower than a niche regulatory filing that reshapes how operators in the startup space have to behave. Read our full methodology for the scoring rubric, our glossary for term definitions, and our trends index for the longitudinal view across the beat.
Sources are only linked to a story once they clear our classification pipeline at a minimum 35 percent relevance threshold. According to that methodology, reviewed July 2026, this follows multi-source corroboration standards recommended by journalism research bodies such as the Reuters Institute for the Study of Journalism.
