Meta's AI Shakeup Spooks Investors While One Health-Care Stock Explodes 36%—See Who's Winning Wall Street's Wild Ride

The stock market saw a flurry of dramatic moves on Monday, with individual company news sparking massive rallies and significant slumps. While the broader indices charted their own course, the real story was in the trenches, where strategic partnerships, analyst praise, and internal shakeups sent specific stocks on a rollercoaster ride.

The Unstoppable Rally: GoodRx's 36% Surge

Leading the pack with a jaw-dropping 36% surge was digital health-care platform GoodRx Holdings. The catalyst for this explosive growth was a blockbuster announcement of a new collaboration with pharmaceutical giant Novo Nordisk. The partnership is set to streamline patient access to popular and in-demand anti-obesity medications, tapping into a booming market and sending investors into a buying frenzy. This move signals a major strategic win for GoodRx, positioning it as a key player in the rapidly expanding weight-loss drug landscape.

Google's Billion-Dollar Bet on AI and Crypto

In the tech sector, TeraWulf, a company specializing in bitcoin mining and AI computing, saw its shares leap by an impressive 13%. The surge came after it was revealed that Google is significantly increasing its stake in the firm. The investment is earmarked to fund a major expansion of TeraWulf's Lake Mariner facility in New York. As part of the deal, Google is providing an additional backstop that brings its total potential financial commitment to a staggering $3.2 billion, a massive vote of confidence that electrified the market.

Wall Street Falls for Duolingo

The popular language-learning app Duolingo also had a stellar day, with its stock popping 12%. The gains were fueled by a wave of positive sentiment from Wall Street analysts. KeyBanc Capital Markets upgraded the stock to overweight, highlighting the company's innovative new products and highly effective viral marketing campaigns as key drivers for future growth. Adding to the bullish momentum, Citigroup also initiated its coverage of Duolingo with a coveted "buy" rating, signaling strong institutional belief in the company's trajectory.

Meta's Misstep

In stark contrast to the day's winners, social media behemoth Meta Platforms saw its stock slide by nearly 3%. The decline followed a report from The Information on Friday, which revealed that the Facebook and Instagram parent is planning yet another major overhaul of its artificial intelligence operations. This would mark the fourth such restructuring in just six months, a detail that appears to have unsettled investors and raised questions about the stability and direction of the company's crucial AI strategy.
