As Nvidia threatens to dethrone Microsoft as the world's most valuable company, at least a few investors are betting its soaring shares will return to earth.

Outstanding short bets against Nvidia stand at about $34 billion, nearly twice as much as what has been bet against Apple and Tesla, the next two biggest short bets combined, according to a report from S3 Partners on Thursday.

Short sellers have bet about $19 billion against Apple and $18 billion against Tesla, S3's data shows.

However, the short bets against Nvidia are equivalent to just 1% of its stock market value, according to LSEG data.

Insatiable demand for its high-end AI processors has sent Nvidia's stock soaring 143% in 2024.

On Wednesday, Nvidia's stock market value reached $1.012 trillion, eclipsing Apple to become the world's second most valuable company.

Nvidia's stock market value retreated almost 2% to $2.96 trillion on Thursday. Microsoft's market value stands at $3.15 trillion after the technology heavyweight's stock climbed 13% year to date.
