The stock opened higher, at $38, so the almost-16% gain refers to the IPO price, not the opening trade.
How Rubrik’s first-day gain is calculated
Rubrik priced its upsized initial public offering at $32 per Class A share on April 24, 2024. The next day, its shares began trading on the New York Stock Exchange under the ticker RBRK. TechCrunch reported that they opened at $38 and finished the session at $37.
| Reference point | Price | What it shows |
|---|---|---|
| IPO offer price | $32 | Price investors paid for shares in the offering, according to Rubrik’s pricing announcement. |
| Opening trade on April 25, 2024 | $38 | First-day opening price reported by TechCrunch. |
| Closing price on April 25, 2024 | $37 | First-day closing price reported by TechCrunch. |
The headline’s percentage compares the $37 close with the $32 offer price: ($37 − $32) ÷ $32 × 100 = 15.625%, or about 15.6%. The opening price was $6 above the offer price, a separate comparison; shares then closed $1 below their opening level.
What the IPO announcement said
Rubrik announced an offering of 23.5 million Class A shares at $32 each on April 24, 2024. Trading began the following day, while the company’s announcement said the offering was expected to close on April 29, subject to customary closing conditions. Those are distinct milestones: a stock can begin trading before the offering’s scheduled closing date.

What the reported valuation refers to
TechCrunch reported a fully diluted valuation of $6.6 billion based on the $38 opening price. It compared that opening-price figure with a $3.5 billion primary valuation in 2019, describing the former as 88% higher. The $6.6 billion figure is therefore tied to the opening price, not the $37 first-day close.

Rubrik is a cybersecurity company that sells cloud-based security software to enterprise customers, as TechCrunch described it. The first-day prices establish how the shares traded relative to the IPO offer price; they do not, by themselves, establish why the price moved. This April 25, 2024, debut snapshot also does not indicate RBRK’s current share price, market capitalization, or investment outlook.
