At $500 billion, OpenAI’s latest valuation is higher than the individual GDPs of more than three-fourths of all nations on Earth.
We won’t opine on whether the business’s fundamentals merit that pricetag. However, we will note that it’s the most dramatic example of a broader trend: Hot private companies posting huge and often sharply rising valuations.
For now, OpenAI has clinched first place as the most valuable private company. But, per Crunchbase data, there are also at least five more private, venture-backed U.S. companies with valuations exceeding $100 billion.
Below, we’ve ranked the top five other companies, including a look at how their valuations have risen in recent quarters
Private valuations taking cues from public markets
Given that many large cap public tech companies have seen large share-price hikes in recent months, particularly for those perceived as leaders in AI, it’s not entirely a shocker to see the most high-profile private companies getting valuation boosts as well.
Still, it’s worth noting that these are unusually large gains in the space of a few months, particularly for GenAI leaders. At current levels, they’re certainly priced with high expectations for future performance.
