2 Stocks Billionaires Can't Stop Buying

Two stocks have been on the radar of prominent billionaire investors, who seem to be unable to resist adding to their shares. Warren Buffett, the founder of Berkshire Hathaway, once expressed regret for not investing earlier in Google (now Alphabet), a company he later became a major shareholder of. In 2025, he began accumulating Alphabet stock, which now accounts for the fourth-largest holding in his conglomerate.

Stanley Druckenmiller and Ken Fisher, two other billionaires, have also increased their positions in Alphabet shares. Fisher Asset Management, managed by Ken Fisher, boosted its stake in Eli Lilly by nearly 5%, while Citadel Advisors, led by Ken Griffin, boosted its position in Lilly by 291%. Lilly is currently Griffin's eighth-largest holding.

While one should not invest solely based on the moves of billionaires, both Alphabet and Lilly have strong potential for long-term growth. Alphabet leads in key technologies such as cloud computing, AI, and quantum computing, while Lilly is a leader in the fast-growing obesity drug market and other areas like cancer, diabetes, and immunology.
