What happens to the index if AI infra spending slows down? Which is inevitable

**Direct + indirect exposure of AI infra stocks on SP500: 25%–35% of the index**

**Highly sensitive (priced on AI infra momentum): 15%–20%**

AI infra spending will slow down, so is QQQ and SP500 not risk positive currently?

These are the companies where AI capex really drives the story:

NVIDIA (5–6%)

Microsoft (6–7%)

Amazon (\~3–4%)

Alphabet (\~3–4%)

Meta Platforms (\~2–3%)

These alone = **\~20% of the S&P 500**

⚙️** Second layer (indirect beneficiaries \~10–15%**)

These benefit from AI infra but aren’t fully dependent:

Broadcom

Advanced Micro Devices

Oracle

Data center REITs, networking, power infra, etc.

So total exposure:

Direct, high sensitivity: ~15–20%

Indirect / moderate sensitivity: ~10–15%

Total AI-influenced weight: ~25–35%

That said, if you had to invest today, where would you put your money?
