GameStop's latest financial report reveals that its $500 million Bitcoin investment, made in May, was valued at approximately $519 million by the end of the third quarter, resulting in $19 million in unrealized gains. This marks a decrease from the $528 million valuation at the end of the second quarter. The company did not add to or sell any of its Bitcoin holdings during the quarter. Despite the gains in its Bitcoin investment, GameStop's stock fell 5% as its financial performance missed expectations, with net sales dropping 4.5% year-over-year to $821 million.
