CyberArk shares soared as much as 18% on Tuesday after The Wall Street Journal reported that cybersecurity provider Palo Alto Networks has held discussions to buy the identity management software maker for over $20 billion.

Cloud security is becoming an increasingly critical piece of the enterprise tech stack, especially as rapid advancements in artificial intelligence bring with them a whole new set of threats, and as ransomware attacks become more commonplace.

Founded in 2005, Palo Alto Networks has emerged in recent years as a consolidator in the cybersecurity industry and has grown into the biggest player in the space by market cap, with a valuation of over $130 billion. CEO Nikesh Arora, who was appointed to the job in 2018, has been on a spending spree, snapping up Protect AI in a deal that closed in July, and in 2023 buying Talon Cyber Security, Dig Security and Zycada Networks.

But CyberArk would represent by far Arora’s biggest bet yet. The Israeli company, which went public in 2014, provides technology that helps companies streamline the process of logging on to applications for employees.

CyberArk faces competition from Microsoft, Okta and IBM‘s HashiCorp. Another rival, SailPoint, returned to the public markets in February.

With Tuesday’s rally, CyberArk shares climbed to a record, surpassing their prior all-time high reached in February. The stock is up 29% this year, pushing the company’s market cap to almost $21 billion, after jumping 52% in 2024. Palo Alto shares, meanwhile, slid 3.5% on the report and are now up about 9% for the year.

Representatives from Palo Alto Networks and CyberArk declined to comment.

During the first quarter, CyberArk generated around $11.5 million in net income on around $318 million in revenue, which was up 43% from a year earlier.

It’s been an active stretch for big deals in the cyber market. Google said in March that it was spending $32 billion on Wiz, its largest acquisition on record by far, and a purchase intended to bolster its cloud business with greater AI security technology.

Networking giant Cisco also made its biggest deal ever in the security space, buying Splunk in 2023 for $28 billion. Splunk’s technology helps businesses monitor and analyze their data to minimize the risk of hacks and resolve technical issues faster.

Spotify shares dropped about 4% Tuesday after the music streaming platform fell short of Wall Street’s expectations and posted weak guidance for the current quarter.

Here’s how the company did versus LSEG estimates:

• Loss: Loss of .42 euros vs earnings of 1.90 euros per share expected
• Revenue: 4.19 billion euros vs. 4.26 billion expected

The Sweden-based music platform’s revenues rose 10% from about 3.81 billion euros in the year-ago period. The company posted a net loss of 86 million euros, or a loss of .42 euros per share, down from net income of 225 million euros, or 1.10 euros per share a year ago.

Third-quarter guidance came up short of Wall Street’s forecast.

The company expects revenues to reach 4.2 billion euros, compared to a 4.47 billion euro estimate from StreetAccount. Spotify said the forecast accounts for a 490-basis-point headwind due to foreign exchange rates.

Monthly active users on the platform jumped 11% to 696 million, while paying subscribers rose 12% from a year ago to 276 million.

For the current quarter, Spotify said it expects to reach 710 million monthly active users, with 14 million net adds. The company expects 5 million net new premium subscribers in the third quarter to reach 281 million subscriptions.

During the period, Spotify said it rolled out a request feature for its artificial intelligence DJ. The company said engagement with the offering has roughly doubled over the last year.

In 2024, Spotify posted its first full year of profitability. Shares are up 57% this year.

South Korean artificial intelligence chip startup Rebellions has raised money from tech giant Samsung and is targeting a funding round of up to $200 million ahead of a public listing, the company’s management told CNBC on Tuesday.

Last year, Rebellions merged with another startup in South Korea called Sapeon, creating a firm that is being positioned as one of the country’s promising rivals to Nvidia.

Rebellions is currently raising money and is targeting funding of between $150 million and $200 million, Sungkyue Shin, chief financial officer of the startup, told CNBC on Tuesday.

Samsung’s investment in Rebellions last week was part of that, Shin said, though he declined to say how much the tech giant poured in.

Since its founding in 2020, Rebellions has raised $220 million, Shin added.

The current funding round is ongoing and Shin said Rebellions is talking to its current investors as well as investors in Korea and globally to participate in the capital raise. Rebellions has some big investors, including South Korean chip giant SK Hynix, telecommunication firms SK Telecom and Korea Telecom, and Saudi Arabian oil giant Aramco.

Rebellions was last valued at $1 billion. Shin said the current round of funding would push the valuation over $1 billion but declined to give specific figure.

Rebellions is aiming for an initial public offering once this funding round has closed.

“Our master plan is going public,” Shin said.

Rebellions designs chips that are focused on AI inferencing rather than training. Inferencing is when a pre-trained AI model interprets live data to come up with a result, much like the answers that are produced by popular chatbots.

With the backing of major South Korean firms and investors, Rebellions is hoping to make a global play where it will look to challenge Nvidia and AMD as well as a slew of other startups in the inferencing space.

Samsung is manufacturing Rebellions’ semiconductor using its 4 nanometer process, which is among the leading-edge chipmaking nodes. For comparison, Nvidia’s current Blackwell chips use the 4 nanometer process from Taiwan Semiconductor Manufacturing Co. Rebellions will also use Samsung’s high bandwidth memory, known as HBM3e. This type of memory is stacked and is required to handle large data processing loads.

That could turn out to be a strategic win for Samsung, which is a very distant second to TSMC in terms of market share in the foundry business. Samsung has been looking to boost its chipmaking division. Samsung Electronics recently entered into a $16.5 billion contract for supplying semiconductors to Tesla.

If Rebellions manages to find a large customer base, this could give Samsung a major customer for its foundry business.
