London Stock Exchange: Raspberry Pi Holdings plc. Striking graph illustrating stock in the UK Raspberry Pi holding company spiking on Tuesday:

The Telegraph credited excitement around OpenClaw:

Raspberry Pi's stock price has surged 30pc in two days, amid chatter on social media that the company's tiny computers can be used to power a popular AI chatbot.

Users have turned to Raspberry Pi's small computers to run a technology known as OpenClaw, a viral AI personal assistant. A flood of posts about the practice have been viewed millions of times since the weekend.

Reuters also credit a stock purchase by CEO Eben Upton:

Shares in Raspberry Pi rose as much as 42% on Tuesday in ‌a record two‑day rally after CEO Eben Upton bought ‌stock in the beaten‑down UK computer hardware firm, halting a months‑long slide, ​as chatter grew that its products could benefit from low‑cost artificial‑intelligence projects.

Two London traders said the driver behind the surge was not clear, though the move followed a filing showing Upton bought ‌about 13,224 pounds ⁠worth of shares at around 282 pence each on Monday.
