Thumzup Media Corporation, a publicly traded company, has amended its Securities and Exchange Commission (SEC) filing to increase its shelf offering from $200 million to $500 million. The company plans to allocate the proceeds from this offering toward expanding its Bitcoin treasury strategy and supporting corporate operations. This move reflects an acceleration in corporate Bitcoin acquisitions. Separately, KULR, another public company, recently acquired an additional 42 bitcoins for approximately $4 million.
