Abel Shifts Berkshire Portfolio into Virtual Monopoly Assets

Greg Abel, Warren Buffett's successor as Berkshire Hathaway CEO, has taken control of the conglomerate's $358 billion investment portfolio. As of September 25, over $42 billion of Berkshire's invested capital is tied up in three virtual monopolies: Alphabet (parent company of Google), Sirius XM Holdings, and VeriSign.

Alphabet, which accounted for more than 91% of worldwide internet search traffic in August, commands exceptional ad-pricing power. Its integration of generative AI and large language model capabilities into Google Cloud has sent sales of this significantly higher-margin operating segment soaring.

Sirius XM Holdings, while not a virtual monopoly per se, is the only licensed satellite-radio operator domestically, giving it legal monopoly status. Berkshire Hathaway holds 37% of its outstanding shares, providing Sirius with above-average subscription pricing power and a revenue mix that produces more consistent operating cash flow during recessions.

VeriSign, another long-held Berkshire investment, enjoys a virtual monopoly in domain-name registration rights for leading .com and .net domains. Its infrastructure expenses are relatively low, and its only other major cost is the fees paid to ICANN, affording VeriSign reasonably strong pricing power and consistently juicy operating margins.
