Elon Musk said Saturday that Twitter users will only be able to read a certain number of posts per day due to “extreme levels of data scraping” and “system manipulation” on the platform.
The Tesla and SpaceX CEO said the limits are temporary, but verified accounts will be able to read 6,000 posts per day, unverified accounts will be able to read 600 posts per day and new unverified accounts will be limited to reading 300 posts per day.
Musk did not say when the restrictions will be lifted.
Musk’s tweet comes as thousands of users reported problems as they tried to access Twitter Saturday, marking the latest widespread outage since he acquired the social media site late last year.
Many users who tried to access or post content on Twitter’s website or mobile app were met with a “Rate limit exceeded” or “Cannot retrieve tweets” error message. As of 11 a.m. ET, more than 7,300 people reported issues with Twitter to the website Downdetector.
Twitter responded to CNBC’s request for comment with its customary poop emoji. It is not immediately clear if the site’s outage is related to Twitter’s new limited-reading policy.
The social media site also began restricting access to content that was available to users without an account on Friday. Twitter had previously allowed people to view public profiles and tweets, even if they had not signed in, but they are now immediately prompted with a log-in window.
Musk said in a tweet Friday that “drastic and immediate action” was necessary due to “EXTREME” levels of data scraping. He added that the restrictions would be “unlocked shortly,” but the content remained restricted as of Saturday afternoon.
Saturday’s outage is not the first time Twitter has suffered technical difficulties in recent months. In February, users were unable to post on the site for about 90 minutes after receiving a message that read, “You are over the daily limit for sending Tweets.” In March, users were temporarily unable to click on links or load images.
Other outages coincided with reports of a data center closure and massive layoffs at Twitter, which Musk claimed were necessary for the financial health of the company.
It is unclear when Saturday’s outage will be resolved.
CORRECTION: This article has been updated to show that Elon Musk is no longer CEO of Twitter. He is CEO of Tesla and SpaceX.
Circle, the company behind the USDC stablecoin, has filed for an initial public offering with the U.S. Securities and Exchange Commission.
The S1 lays the groundwork for Circle’s long-anticipated entry into the public markets.
While the filing does not yet disclose the number of shares or a price range, sources told Fortune that Circle plans to move forward with a public filing in late April and is targeting a market debut as early as June.
JPMorgan Chase and Citi are reportedly serving as lead underwriters, and the company is seeking a valuation between $4 billion and $5 billion, according to Fortune.
This marks Circle’s second attempt at going public. A prior SPAC merger with Concord Acquisition Corp collapsed in late 2022 amid regulatory challenges. Since then, Circle has made strategic moves to position itself closer to the heart of global finance — including the announcement last year that it would relocate its headquarters from Boston to One World Trade Center in New York City.

Circle is best known as the issuer of USDC, the world’s second-largest stablecoin by market capitalization.
Pegged one-to-one to the U.S. dollar and backed by cash and short-term Treasury securities, USDC has roughly $60 billion in circulation.
Circle is best known as the issuer of USDC, the world’s second-largest stablecoin by market capitalization.
Pegged one-to-one to the U.S. dollar and backed by cash and short-term Treasury securities, USDC has roughly $60 billion in circulation. It makes up about 26% of the total market cap for stablecoins, behind Tether‘s 67% dominance. Its market cap has grown 36% this year, however, compared with Tether’s 5% growth.
Coinbase CEO Brian Armstrong said on the company’s most recent earnings call that it has a “stretch goal to make USDC the number 1 stablecoin.”
The company’s push into public markets reflects a broader moment for the crypto industry, which is navigating renewed political favor under a more crypto-friendly U.S. administration. The stablecoin sector is ramping up as the industry grows increasingly confident that the crypto market will get its first piece of U.S. legislation passed and implemented this year, focusing on stablecoins.
Stablecoins’ growth could have investment implications for crypto exchanges like Robinhood and Coinbase as they integrate more of them into crypto trading and cross-border transfers. Coinbase also has an agreement with Circle to share 50% of the revenue of its USDC stablecoin.
The stablecoin market has grown about 11% so far this year and about 47% in the past year, and has become a “systemically important” part of the crypto market, according to Bernstein. Historically, digital assets in this sector have been used for trading and as collateral in decentralized finance (DeFi), and crypto investors watch them closely for evidence of demand, liquidity and activity in the market.
More recently, however, rhetoric around stablecoins’ ability to help preserve U.S. dollar dominance – by exporting dollar utility internationally and ensuring demand for U.S. government debt, which backs nearly all dollar-denominated stablecoins – has grown louder.
A successful IPO would make Circle one of the most prominent crypto-native firms to list on a U.S. exchange — an important signal for both investors and regulators as digital assets become more entwined with the traditional financial system.

Hims & Hers Health shares closed up 5% on Tuesday after the company announced patients can access Eli Lilly‘s weight loss medication Zepbound and diabetes drug Mounjaro, as well as the generic injection liraglutide, through its platform.
Zepbound, Mounjaro and liraglutide are part of the class of weight loss medications called GLP-1s, which have exploded in popularity in recent years. Hims & Hers launched a weight loss program in late 2023, but its GLP-1 offerings have evolved as the company has contended with a volatile supply and regulatory environment.
Lilly’s weekly injections Zepbound and Mounjaro will cost patients $1,899 a month, according to the Hims & Hers website. The generic liraglutide will cost $299 a month, but it requires a daily injection and can be less effective than other GLP-1 medications.
“As we look ahead, we plan to continue to expand our weight loss offering to deliver an even more holistic, personalized experience,” Dr. Craig Primack, senior vice president of weight loss at Hims & Hers, wrote in a blog post.
A Lilly spokesperson said in a statement that the company has “no affiliation” with Hims & Hers and noted that Zepbound is available at lower costs for people who are insured for the product or for those who buy directly from the company.
In May, Hims & Hers started prescribing compounded semaglutide, the active ingredient in Novo Nordisk‘s GLP-1 weight loss medications Ozempic and Wegovy. The offering was immensely popular and helped generate more than $225 million in revenue for the company in 2024.
But compounded drugs can traditionally only be mass produced when the branded medications treatments are in shortage. The U.S. Food and Drug Administration announced in February that the shortage of semaglutide injections products had been resolved.
That meant Hims & Hers had to largely stop offering the compounded medications, though some consumers may still be able to access personalized doses if it’s clinically applicable.
During the company’s quarterly call with investors in February, Hims & Hers said its weight loss offerings will primarily consist of its oral medications and liraglutide. The company said it expects its weight loss offerings to generate at least $725 million in annual revenue, excluding contributions from compounded semaglutide.
But the company is still lobbying for compounded medications. A pop up on Hims & Hers’ website, which was viewed by CNBC, encourages users to “use your voice” and urge Congress and the FDA to preserve access to compounded treatments.
With Tuesday’s rally, Hims and Hers shares are up about 27% in 2025 after soaring 172% last year.

Meta’s head of artificial intelligence research announced Tuesday that she will be leaving the company.
Joelle Pineau, the company’s vice president of AI research, announced her departure in a LinkedIn post, saying her last day at the social media company will be May 30.
Her departure comes at a challenging time for Meta. CEO Mark Zuckerberg has made AI a top priority, investing billions of dollars in an effort to become the market leader ahead of rivals like OpenAI and Google.
Zuckerberg has said that it is his goal for Meta to build an AI assistant with more than 1 billion users and artificial general intelligence, which is a term used to describe computers that can think and take actions comparable to humans.
“As the world undergoes significant change, as the race for AI accelerates, and as Meta prepares for its next chapter, it is time to create space for others to pursue the work,” Pineau wrote. “I will be cheering from the sidelines, knowing that you have all the ingredients needed to build the best AI systems in the world, and to responsibly bring them into the lives of billions of people.”

Pineau was one of Meta’s top AI researchers and led the company’s fundamental AI research unit, or FAIR, since 2023. There, she oversaw the company’s cutting-edge computer science-related studies, some of which are eventually incorporated into the company’s core apps.
She joined the company in 2017 to lead Meta’s Montreal AI research lab. Pineau is also a computer science professor at McGill University, where she is a co-director of its reasoning and learning lab.
Some of the projects Pineau helped oversee include Meta’s open-source Llama family of AI models and other technologies like the PyTorch software for AI developers.
Pineau’s departure announcement comes a few weeks ahead of Meta’s LlamaCon AI conference on April 29. There, the company is expected to detail its latest version of Llama. Meta Chief Product Officer Chris Cox, to whom Pineau reported to, said in March that Llama 4 will help power AI agents, the latest craze in generative AI. The company is also expected to announce a standalone app for its Meta AI chatbot, CNBC reported in February.
“We thank Joelle for her leadership of FAIR,” a Meta spokesperson said in a statement. “She’s been an important voice for Open Source and helped push breakthroughs to advance our products and the science behind them.”
Pineau did not reveal her next role but said she “will be taking some time to observe and to reflect, before jumping into a new adventure.”
