Datadog shares were up 10% in extended trading on Wednesday after S&P Global said the monitoring software provider will replace Juniper Networks in the S&P 500 U.S. stock index.

S&P Global is making the change effective before the beginning of trading on July 9, according to a statement.

Computer server maker Hewlett Packard Enterprise, also a constituent of the index, said earlier on Wednesday that it had completed its acquisition of Juniper, which makes data center networking hardware. HPE disclosed in a filing that it paid $13.4 billion to Juniper shareholders.

Over the weekend, the two companies reached a settlement with the U.S. Justice Department, which had sued in opposition to the deal. As part of the settlement, HPE agreed to divest its global Instant On campus and branch business.

While tech already makes up an outsized portion of the S&P 500, the index has has been continuously lifting its exposure as the industry expands into more areas of society.

DoorDash was the latest tech company to join during the last rebalancing in March. Cloud software vendor Workday was added in December, and that was preceded earlier in 2024 with the additions of Palantir, Dell, CrowdStrike, GoDaddy and Super Micro Computer.

Stocks often rally when they’re added to a major index, as fund managers need to rebalance their portfolios to reflect the changes.

New York-based Datadog went public in 2019. The company generated $24.6 million in net income on $761.6 million in revenue in the first quarter of 2025, according to a statement. Competitors include Cisco, which bought Splunk last year, as well as Elastic and cloud infrastructure providers such as Amazon and Microsoft.

Datadog has underperformed the broader tech sector so far this year. The stock was down 5.5% as of Wednesday’s close, while the Nasdaq was up 5.6%. Still, with a market cap of $46.6 billion, Datadog’s valuation is significantly higher than the median for that index.

Stocks tied to the price of ether, better known as ETH, were higher on Wednesday, reflecting renewed enthusiasm for the crypto asset amid a surge of interest in stablecoins and tokenization.

BitMine Immersion Technologies, a bitcoin miner that announced plans this week to make ETH its primary treasury reserve asset, jumped about 20%. It’s gained more than 1,000% since the announcement. Betting platform SharpLink Gaming, which has also initiated an ETH treasury strategy, added more than 11%. Bit Digital, which last week exited bitcoin mining to focus on its ETH treasury and staking plans, jumped more than 6%.

“We’re finally at the point where real use cases are emerging, and stablecoins have been the first version of that at scale but they’re going to open the door to a much bigger story around tokenizing other assets and using digital assets in new ways,” Devin Ryan, head of financial technology research at Citizens.

On Tuesday, as bitcoin ETFs snapped a 15-day streak of inflows, ether ETFs saw $40 million in inflows led by BlackRock’s iShares Ethereum Trust. ETH ETFs came back to life in June after much concern that they were becoming zombie funds.

The price of the coin itself was last higher by 5%, according to Coin Metrics, though it’s still down 24% this year.

Ethereum has been struggling with an identity crisis fueled by uncertainty about the network’s value proposition, weaker revenue since its last big technical upgrade and increasing competition from Solana. Market volatility, driven by geopolitical uncertainty this year, has not helped.

The Ethereum network’s smart contracts capability makes it a prominent platform for the tokenization of traditional assets, which includes U.S. dollar-pegged stablecoins. Fundstrat’s Tom Lee this week called Ethereum “the backbone and architecture” of stablecoins. Both Tether (USDT) and Circle‘s USD Coin (USDC) are issued on the network.

BlackRock’s tokenized money market fund (known as BUIDL, which stands for USD Institutional Digital Liquidity Fund) also launched on Ethereum last year before expanding to other blockchain networks.

Tokenization is the process of issuing digital representations on a blockchain network of publicly traded securities, real world assets or any other form of value. Holders of tokenized assets don’t have outright ownership of the assets themselves.

The latest wave of interest in ETH-related assets follows an announcement by Robinhood this week that it will enable trading of tokenized U.S. stocks and ETFs across Europe, after a groundswell of interest in stablecoins throughout June following Circle’s IPO and the Senate passage of its proposed stablecoin bill, the GENIUS Act.

Ether, which turns 10 years old at the end of July, is sitting about 75% off its all-time high.

One of the most popular gaming YouTubers is named Bloo, and has bright blue wavy hair and dark blue eyes. But he isn’t a human — he’s a fully virtual personality powered by artificial intelligence.

“I’m here to keep my millions of viewers worldwide entertained and coming back for more,” said Bloo in an interview with CNBC. “I’m all about good vibes and engaging content. I’m built by humans, but boosted by AI.”

Bloo is a virtual YouTuber, or VTuber, who has built a massive following of 2.5 million subscribers and more than 700 million views through videos of him playing popular games like Grand Theft Auto, Roblox and Minecraft. VTubers first gained traction in Japan in the 2010s. Now, advances in AI are making it easier than ever to create VTubers, fueling a new wave of virtual creators on YouTube.

The virtual character – whose bright colors and 3D physique look like something out of a Pixar film or the video game Fortnite – was created by Jordi van den Bussche, a long time YouTuber also known as kwebbelkop. Van den Bussche created Bloo after finding himself unable to keep up with the demands of content creation. The work no longer matched the output.

“Turns out, the flaw in this equation is the human, so we need to somehow remove the human,” said van den Bussche, a 29-year old from Amsterdam, in an interview. “The only logical way was to replace the human with either a photorealistic person or a cartoon. The VTuber was the only option, and that’s where Bloo came from.”

Bloo has already generated more than seven figures in revenue, according to van den Bussche. Many VTubers like Bloo are “puppeteered,” meaning a human controls the character’s voice and movements in real time using motion capture or face-tracking technology. Everything else, from video thumbnails to voice dubbing in other languages, is handled by AI technology from ElevenLabs, OpenAI’s ChatGPT, Google’s Gemini and Anthropic’s Claude. Van den Bussche’s long-term goal is for Bloo’s entire personality and content creation process to be run by AI.

Van den Bussche has already tested fully AI-generated videos on Bloo’s channel, but says the results have not yet been promising. The content doesn’t perform as well because the AI still lacks the intuition and creative instincts of a human, he said. 

“When AI can do it better, faster or cheaper than humans, that’s when we’ll start using it permanently,” van den Bussche said.

The technology might not be far away.

Startup Hedra offers a product that uses AI technology to generate videos that are up to five minutes long. It raised $32 million in a funding round in May led by Andreessen Horowitz’s Infrastructure fund.

Hedra’s product, Character-3, allows users to create AI-generated characters for videos and can add dialogue and other characteristics. CEO Michael Lingelbach told CNBC Hedra is working on a product that will allow users to create self-sustaining, fully-automated characters.

“We’re doing a lot of research accelerating models like Character-3 to real time, and that’s going to be a really good fit for VTubers,” Lingelbach said. 

Character-3’s technology is already being used by a growing number of creators who are experimenting with new formats, and many of their projects are going viral. One of those is comedian Jon Lajoie’s Talking Baby Podcast, which features a hyper-realistic animated baby talking into a microphone. Another is Milla Sofia, a virtual singer and artist whose AI-generated music videos attract thousands of views. 

These creators are using Character-3 to produce content that stands out on social media, helping them reach wide audiences without the cost and complexity of traditional production.

AI-generated video is a rapidly evolving technology that is reshaping how content is made and shared online, making it easier than ever to produce high-quality video without cameras, actors or editing software. In May, Google announced Veo 3, a tool that creates AI-generated videos with audio.

Google said it uses a subset of YouTube content to train Veo 3, CNBC reported in June. While many creators said they were unaware of the training, experts said it has the potential to create an intellectual property crisis on the platform.

“The age of slop is inevitable,” said Ajder, who is also an AI policy advisor at Meta, which owns Facebook and Instagram. “I’m not sure what we do about it.”

While it’s not new, the surge in this type of content has led to growing criticism from users who say it’s harder to find meaningful or original material, particularly on apps like TikTok, YouTube and Instagram.

“I am actually so tired of AI slop,” said one user on X. “AI images are everywhere now. There is no creativity and no effort in anything relating to art, video, or writing when using AI. It’s disappointing.”

However, the creators of this AI content tell CNBC that it comes down to supply and demand. As the AI-generated content continues to get clicks, there’s no reason to stop creating more of it, said Noah Morris, a creator with 18 faceless YouTube channels.

Some argue that AI videos still have inherent artistic value, and though it’s become much easier to create, slop-like content has always existed on the internet, Lingelbach said.

“There’s never been a barrier to people making uninteresting content,” he said. “Now there’s just more opportunity to create different kinds of uninteresting content, but also more kinds of really interesting content too.”
