180 Life Sciences Corp (ATNF) experienced a dramatic after-hours plunge of 8.79% on Wednesday, capping off a day of extreme volatility for the stock. This downturn follows a roller-coaster trading session that saw the company's shares soar in pre-market trading before reversing course during regular hours.

The volatility stems from a major announcement that 180 Life Sciences is rebranding as ETHZilla, pivoting from life sciences to become an Ethereum-focused corporate treasury vehicle. This news, coupled with the revelation that billionaire tech investor Peter Thiel is part of an investor group holding a 7.5% stake in the company, initially drove the stock up 57% in pre-market trading, extending a 206.6% rally from the previous day.

However, investor sentiment appeared to shift dramatically during regular trading hours, with the stock closing down 5.08%. The after-hours plunge suggests continued skepticism about the company's abrupt strategic shift and potential profit-taking by early investors. As 180 Life Sciences transitions into its new identity as ETHZilla, market participants are closely monitoring how this pivot will impact the company's performance in the volatile cryptocurrency market.
