Warren Buffett hasn't closed a major takeover since 2016, and if precedent is anything to go by, the next one will be colossal.

Berkshire Hathaway is sitting on a $137 billion cash pile, and even as valuations tank amid the pandemic-fueled downturn, Buffett isn't chasing any deals. While some companies approached Berkshire for aid, the Federal Reserve's move into corporate bond purchases erased any chances for a near-term acquisition, Buffett said at Berkshire's annual shareholder meeting in early May.

"We haven't done anything because we don't see anything that attractive to do," the CEO said. "The companies we were getting calls from, after the Fed acted, a number of them were able to get money in the public market frankly at terms we wouldn't have given."

"Now that could change very quickly or it may not change," he added, referring to Berkshire's lack of targets.

Whenever Buffett does find a new firm to add to his corporate empire, expect the Oracle of Omaha to shell out hundreds of millions, if not billions, of dollars.
