Warren Buffett’s Berkshire Hathaway may be sitting on a sizeable paper profit from its recent Alphabet investment, with current market prices implying an unrealized gain of around $1.4 billion, if the conglomerate still holds the shares it disclosed last quarter.

Berkshire disclosed in its November filing that it owned about 17.8 million Alphabet shares, valued at $4.3 billion at the time.

With the stock now trading around the low $320 range, that stake would be worth close to $5.7 billion, putting the unrealized gain at $1.4 billion.

Alphabet continued to rise today as investors reacted to reports that Meta is evaluating Google’s TPUs as an alternative to Nvidia chips for powering its AI systems. With the latest uptick, Alphabet’s shares have gained about 24% in a month and roughly 70% so far this year, per Yahoo Finance.
