Billionaire Ken Griffin is one of the richest people in the world. His net worth, according to Forbes Magazine, sits at $50.4 billion as of June 2026. Griffin’s net worth is courtesy of his hedge fund Citadel. Citadel is an alternative investment manager that has been in the business for 35 years. Griffin is Citadel’s founder and CEO, and his firm is one of the world’s most successful hedge funds.

The firm kept up to its reputation in 2025 when two of its funds closed with strong gains. According to data sourced by CNBC, Citadel’s Wellington fund gained 10.2% in 2025 while its tactical trading fund gained 18.6%. On the other hand, the S&P 500, which contended with significant market volatility stemming from conflict in the Middle East and tariffs, gained 16.4% during the year. As per Business Insider, year-to-date as of April 2026, the Wellington fund was up by 2.4% while the tactical fund was up by 8.3%.

Like several other hedge fund managers, Griffin also regularly makes public appearances. One recent appearance came during the Milken 2026 Global Conference in May. At the event, Griffin discussed the ongoing conflict in Iran and addressed its impact on the markets. He commented on some of the reasons why the conflict had not significantly affected the stock market:

“Well first of all, there is a sense that the worst case scenarios are off the table. The Iranian military has been successfully contained but they have not been defeated. In this stalemate situation, the price of energy has clearly gone higher. The United States, holistically, is largely shielded from that. Now the consumer, not, but, fuel efficiency much higher than it was 30 years ago. Dependency upon automobiles for transportation less than 30 years on a per capita basis. . .our ability to withstand this price shock in oil is much greater than it is than anytime in the history of our country.”

13. Alphabet Inc. (NASDAQ:GOOGL)

Citadel’s Stake: $689 million 

Technology giant Alphabet Inc. (NASDAQ:GOOGL)’s shares are up by 106% over the past year and 15% year-to-date. Bank of America discussed the firm on June 4th after Alphabet’s latest capital announcement. It reiterated a Buy rating for the shares and commented that the firm could see healthy capital expenditure in 2026 or 2027 following the raise.

BofA’s coverage came a day after Alphabet Inc. (NASDAQ:GOOGL) revealed that its Gemini app’s engagement had grown to 900 million active users as of May and added that paid subscriptions sat at 350 million. The firm used the statistics to announce an $84.75 billion capital raise.

Alphabet Inc. (NASDAQ:GOOGL) trades at a forward price-to-earnings ratio of 25.06, which is lower than the market’s 30.89. Piper Sandler raised the firm’s share price target to $445 from $425 and kept an Overweight rating on the stock on June 1st.

PBCM discussed Alphabet Inc. (NASDAQ:GOOG) in its fourth quarter 2025 investor letter:

“Alphabet Inc. (NASDAQ:GOOG) also landed on the list of top 5 contributors for a second consecutive quarter. The company appears to be one of the biggest beneficiaries of the AI transition, and their Gemini Large Language Model (LLM) has established itself as a leading LLM along with Claude and ChatGPT. Perception has come a long way from when we first purchased GOOG in March 2023 when the prevailing consensus was that GOOG missed the AI boom and its monopoly on search would deteriorate rapidly.

Unfortunately, in our view investors may have become too enthusiastic about Alphabet’s prospects, pushing the share price well ahead of our most optimistic view of its intrinsic value. As a result, we made the decision to exit our position this quarter and redeployed the funds into a new position. It is always difficult to sell our compounders, and GOOG certainly qualifies as one; but when a stock price moves 10% or more above the top end of our estimated range of intrinsic values, we would no longer be investing but rather speculating.”

12. JPMorgan Chase & Co. (NYSE:JPM)

Citadel’s Stake: $715 million 

Banking giant JPMorgan Chase & Co. (NYSE:JPM)’s shares are up by 16.6% over the past year and are down by 4.4% year-to-date. Its CEO, Jamie Dimon, makes regular media appearances. In an investor conference on May 27th, Dimon revealed that JPMorgan Chase & Co. (NYSE:JPM) could spend between $10 billion and $20 billion for an acquisition over the coming years. The CEO added that the acquisition would have to add to his bank’s operations, culture, and core operations. JPMorgan Chase & Co. (NYSE:JPM) also announced a tokenized money fund in May after it revealed the JPMorgan OnChain Liquidity-Token Money Market Fund. This fund will be on the Ethereum blockchain and is designed to support stablecoin issuance.

JPMorgan Chase & Co. (NYSE:JPM) currently trades at a forward price-to-earnings ratio of 13.72, which is roughly in line with the sector’s 13.04.

CNBC’s Jim Cramer discussed the firm on Mad Money on June 2nd. Here is what he said:

“But honestly, if you’re looking for a fortress, I like the stock of JPMorgan here. It’s got balanced growth, sells for only 13 times earnings. It’s the best bank in the world…. I’m not going to give you the performance of Micron by telling you to buy JPMorgan. You’re not going to get it. But anyway, you’re not that early in Micron. You could be early in JPMorgan.

JPMorgan’s the antithesis of Micron. You normally don’t get to buy the stock so cheap, and no one would regard it as a lousy franchise even if the stock’s down 7% year to date. You can buy JPMorgan and put it away. Mighty hard to buy and put any tech stocks away right now.”
