\*\*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?
