But you don’t need to buy Tesla or wait for xAI to IPO to benefit. One overlooked public company is supplying the critical tech behind Musk’s AI push — and it trades for a fraction of Nvidia’s price.

Instead, he’s urging investors to consider a little-known hardware company that’s already starting to take off. In fact, while Nvidia has slipped over the past 30 days, this “off-the-radar” stock is up 18% — and Eric believes the run is just beginning.See Eric’s full analysis and get all 7 free trade ideas here5/14/2024 Platinum Investment Management Ltd.145,966$5.10M0.2%-13.0%0.279% 5/10/2024 Vanguard Group Inc.1,861,469$65.08M0.0%-0.7%3.561% 5/10/2024 MMCAP International Inc.
