Chewy Inc. (CHWY) shares are having a strong Monday, and the catalyst appears to be a serious vote of confidence from one of the hedge fund world's heavyweights. Viking Global Investors, the firm run by Andreas Halvorsen, has dramatically increased its bet on the online pet retailer, suggesting that smart money sees something the market might be missing.
A Hedge Fund Doubles Down
Here's what happened: Viking Global boosted its Chewy position by nearly 147% on December 18, 2025. That's not a minor adjustment or portfolio rebalancing. The firm added over 8 million shares, bringing its total ownership to approximately 13.5 million shares valued at around $437 million. When a sophisticated investor like Viking makes a move this bold, markets tend to pay attention.
The signal here is that Viking believes Chewy's current stock price doesn't reflect the durability of its core business, particularly its subscription-heavy revenue stream. Pet owners who sign up for automated deliveries of food and supplies tend to stick around, creating predictable recurring revenue. That's the kind of business model that can weather rough patches, and Viking apparently thinks the market is undervaluing that stability.
What makes this especially interesting is that Viking's average purchase price sits above current trading levels. This isn't a quick flip. It's a multi-quarter bet that Chewy's fundamentals will stabilize and market sentiment will eventually catch up. The accumulation signals rising confidence that the stock's downside may be limited at these levels, even though shares have struggled over the past year.
Market Context and Sector Performance
Monday's broader market is showing mixed performance, with the Russell 2000 up 0.21% and the S&P 500 gaining 0.08%. Chewy's climb is happening alongside strength in the consumer discretionary sector. The State Street Consumer Discretionary Select Sector SPDR ETF (XLY) is up 0.4%, indicating that Chewy's move aligns with broader sector trends rather than being completely isolated.
