GameStop Corp. shares were tumbling Thursday after the company announced that it plans to raise more debt — a move that could indicate another bitcoin purchase is looming for the videogame retailer and original meme stock.

Following the March announcement of the bitcoin treasury strategy, GameStop raised $1.3 billion through another convertible note offering. The company subsequently purchased 4,710 bitcoin for roughly $500 million during May. GME shares were lower by 10% in after hours trading.
