Japanese Bitcoin investment firm Metaplanet has set out one of the most ambitious financing plans in the digital asset sector, filing a shelf registration on August 1 to raise up to 555 billion yen ($3.6 billion).

The company intends to use proceeds from a two-year issuance of perpetual preferred stock to fund its acquisition of 210,000 Bitcoin by 2027.

The strategy would increase its current holdings more than thirteen times, positioning the Tokyo-listed company as one of the largest corporate holders of Bitcoin, second only to MicroStrategy.
