Top Investors Reveal Q2 2026 Portfolios Highlighting Big Bets on Alphabet and SpaceX

Every quarter, major investors managing over $100 million disclose their portfolios via SEC filings, offering insight into Wall Street's biggest moves. Following the end of Q2 2026, Globe reviewed five prominent portfolios: Berkshire Hathaway, ARK Invest, Pershing Square, Bridgewater Associates, and the young hedge fund Situational Awareness.

A clear trend among these investors is massive buying of Alphabet (Google) shares, which rose about 20% in Q2 and hit an all-time high during the period. Berkshire Hathaway, under Greg Abel after Warren Buffett's era, deployed over $17 billion to increase its Alphabet holdings to approximately $37.8 billion, making it the fourth-largest position in its portfolio at 12.6%. Abel also boosted stakes in Delta Airlines and Macy's, funding these moves by reducing positions in Bank of America, Kroger, and fully exiting Constellation Brands.

ARK Invest, led by Cathy Wood, continued its aggressive tech bets, notably purchasing $765 million in SpaceX shares post-IPO and increasing Alphabet and Nvidia holdings. Wood’s portfolio has a 12.5% exposure to Elon Musk’s companies. She also increased investments in Eli Lilly and defense firm Kratos while cutting nearly half of her AMD shares after its 176% surge.

In contrast, billionaire Bill Ackman and Pershing Square fully exited Alphabet, trimmed Amazon and Brookfield, and fortified core holdings like Uber and Microsoft. Ackman also made significant purchases in Mastercard, Visa, S&P Global, and Netflix.

Bridgewater’s Ray Dalio shifted away from chip stocks toward defensive sectors, energy, and space. He expanded SpaceX holdings by $719 million to $4 billion, increased Shell nearly fivefold, and made a remarkable 24,000% gain investment in PC&G. Dalio sold most Micron and TSMC shares and reduced exposure to Amazon, AMD, and Marvell.

The most dramatic story is 25-year-old Leopold Aschenbrener of Situational Awareness, whose portfolio nearly doubled in Q2 to $20.3 billion before a sharp collapse. He made leveraged, concentrated bets on AI memory and chip infrastructure, increasing Micron by 27,712% and Sandisk to $5.7 billion, while massively expanding TSMC and opening a $1.2 billion position in cloud infrastructure firm Nebius. These moves were financed by fully exiting Intel and AMD.

These disclosures reveal divergent strategies but a shared focus on technology, with Alphabet and SpaceX as standout winners in Q2 2026.

Summary: In Q2 2026, top investors revealed portfolios showing heavy investments in Alphabet and SpaceX, with Berkshire Hathaway and ARK Invest leading big purchases, while others like Bill Ackman exited Alphabet. Young hedge fund manager Leopold Aschenbrener made massive leveraged bets on AI chip stocks before a sharp downturn.
