Nearly $2 billion worth of bitcoin was held by Tesla at the conclusion of 2021, according to the company.

• Tesla announced on Monday that it had $1.99 billion in bitcoin at the end of 2021.
• The company purchased a total of $1.5 billion in bitcoin in 2021.

Nearly $2 billion in bitcoin was held by the company at the end of last year, as stated in a filing with the SEC on Monday.

In 2021, the company bought $1.5 billion worth of bitcoin, with the cryptocurrency finishing the year up nearly 60% and trading above $46,000 on Dec. 31. Bitcoin had fallen as low as $30,000 in July due to regulatory concerns in China, but later rallied to an all-time high above $68,000 by early November. On Monday morning, bitcoin was trading just below $43,000.

In May, Tesla stopped accepting bitcoin as a payment option due to environmental concerns.

Tesla does not treat bitcoin as a mark-to-market asset, meaning its earnings are not affected by the value of the currency unless it buys or sells it. As a result, the decline in the value of bitcoin will not impact Tesla's earnings if it has not sold any of its holdings.

In 2021, Tesla recorded a loss of $101 million from its bitcoin investment due to a drop in value, as stated in a filing with the SEC. However, Tesla also made gains of $128 million after selling a portion of its holdings in March, resulting in a total gain of $27 million in its crypto transactions. This gain was recorded as a negative loss in restructuring and other expenses.
