How to Invest in Photonic NPU Technology

Investment Thesis: Why Photonic NPU Now?

The AI Hardware Crisis

Current AI infrastructure is hitting fundamental limits:

Power Wall: Training GPT-5+ scale models would require gigawatts of power
Cost Explosion: AI inference costs are becoming unsustainable
Heat Problem: Data centers can't cool current AI chips efficiently
Speed Bottleneck: Electronic computing can't keep up with AI model growth

Photonic NPUs solve all four problems - making them not just an improvement, but a necessity for AI's next phase.

📈 Market Opportunity

$500M → $15B+ (2024-2030)
30x growth in 6 years
60%+ CAGR

⏰ Timing

Early commercial phase. First products shipping. 2-3 years before mainstream adoption.

🎯 Catalysts

Lightmatter IPO expected 2026-2027. Major cloud provider adoption. First killer apps emerging.

⚠️ Risks

Technology risk. Market adoption uncertainty. Competition from electronic NPUs. Manufacturing challenges.

Public Stock Opportunities

Publicly traded companies with exposure to photonic AI computing.

Strategic partnerships (Lightmatter)
Established silicon photonics revenue
Diversification beyond struggling CPU business

❌ Cons:

Photonics is small % of revenue today
Company execution challenges
Primarily supplier, not platform owner

Strategy: Long-term hold. Photonics upside not fully priced in. Options: Buy the dip if stock <$20. Covered calls to generate income.

IBM
