SoftBank Group's successful IPO of Arm Holdings has put the company in a position to resume its acquisition spree. Arm's shares surged 25% on its first day of trading, doubling SoftBank's initial acquisition price. The IPO will enable SoftBank to use Arm's shares as collateral, improve its credit rating, and take out margin loans. Analysts believe that SoftBank's timing for acquisitions is favorable due to depressed valuations and a lack of funding for early-stage startups.
