NEW YORK, Aug 14 (Reuters) - Billionaire investor Daniel

Loeb's hedge fund Third Point took a stake in Warner Bros.

Discovery ( WBD ) in the second quarter, according to a

regulatory filing published on Friday.

The position of 20 million shares would make the fund one of the

media company's 20 largest investors, according to LSEG data, at

a time when its $110 billion acquisition by Paramount Skydance ( PSKY )

has been put on pause amid court challenges.

Third Point has a long history of investing in the media

industry, including pushing for change at The Walt Disney

Company ( DIS ) in 2022.

The New York-based fund also disclosed that it had increased its

stake in Google parent Alphabet, as well as boosted

its holdings of both Union Pacific ( UNP ) and Norfolk Southern ( NSC )

, as the two railway operators pursue their $85 billion

merger.

Among other new investments disclosed in the 13F filing were a

position in Riot Platforms ( RIOT ), making Third Point one of

the bitcoin miner's 25 largest investors, as well as a stake in

payments processor Block and a small holding in Elon

Musk's SpaceX.
