This Pharma Deal Just Sent One Stock Soaring 36% – Meanwhile, Meta's AI Woes Continue and a Bitcoin Miner Gets a Huge Boost from Google

The stock market saw a whirlwind of activity on Monday, with several companies making jaw-dropping moves that left investors buzzing. While the broader indices remained relatively calm, a handful of stocks experienced dramatic surges and tumbles driven by blockbuster deals, glowing analyst reports, and unsettling internal shakeups. Topping the list was a digital health company that saw its value explode by over a third in a single session.

GoodRx Holdings was the undisputed star of the day, with its stock skyrocketing an astonishing 36%. The catalyst for this massive rally was the announcement of a strategic collaboration with pharmaceutical giant Novo Nordisk. The partnership aims to improve patient access and affordability for Novo Nordisk's popular anti-obesity medications, a market experiencing explosive growth. This move was seen as a major coup for the digital healthcare platform, directly connecting it to one of the hottest sectors in medicine and sending its shares into the stratosphere.

It wasn't just healthcare making waves. The popular language-learning app Duolingo also had a stellar day, jumping 12% after receiving a double dose of love from Wall Street. KeyBanc Capital Markets upgraded the stock to an overweight rating, pointing to the company's viral marketing success and a promising pipeline of new products as key drivers for future growth. Adding to the bullish sentiment, Citigroup initiated its coverage with a buy rating, signaling strong institutional confidence in the education tech firm's trajectory.

In a move that caught many by surprise, Bitcoin miner TeraWulf saw its shares surge 13%. The reason? A significant vote of confidence from none other than Google. The tech behemoth is hiking its stake in TeraWulf to help fund the expansion of the company's facility in New York, which is pivoting to support AI computing alongside its crypto operations. Google is providing a massive financial backstop, now totaling around $3.2 billion, a clear signal of its belief in TeraWulf's potential in the high-demand AI infrastructure space.

However, it wasn't all good news in the tech world. Meta Platforms, the parent company of Facebook and Instagram, found itself on the losing end, with its stock slipping nearly 3%. The dip followed a report that the social media giant is planning yet another major overhaul of its artificial intelligence division—the fourth such restructuring in just six months. This constant shuffling has seemingly unnerved investors, raising questions about the stability and direction of Meta's strategy as it scrambles to compete in the critical AI arms race. Monday's trading was a clear illustration of a market in flux, where strategic partnerships can create immense value overnight, while signs of internal instability can punish even the largest players.
