How S&P 500 inclusion forces buying
When a company is added to the S&P 500, every fund that tracks the index must buy shares so that the new stock’s weight matches its share of the index.
Two numbers matter:
Bloom’s market cap
Current market cap:
$78.16B
Total S&P 500 market cap
As of mid‑2026: ~
$45 trillion (S&P Global data; widely reported).
➤ Bloom’s index weight
Weight=78.16𝐵/45𝑇≈0.17%
📌 2. How many shares index funds must buy
To estimate the forced buying, we use:
Total AUM directly tracking the S&P 500: ~
$7.5 trillion
(Vanguard, BlackRock, State Street combined + smaller index funds)
Required dollar purchase:
7.5𝑇×0.17%≈
$12.75𝐵
Bloom’s share price:
