. The company has arranged a $20 billion margin loan secured against its stake in chip designer Arm, but its attempt to use its OpenAI holding as collateral for another loan has stalled as lenders grew more cautious about extending credit backed by private companies1

1

. In August, SoftBank secured a $10 billion loan from financial institutions using its OpenAI stake as collateral, though negotiations were delayed due to challenges in valuing the privately held company4

4

. S&P Global Ratings estimated SoftBank's loan-to-value ratio at 33% in March, significantly higher than the company's internal calculation of 17%, though the ratings agency expects this figure to have dropped to between 20% and 25% by June1

. Makiko Yoshimura from S&P Global Ratings noted that "Arm has a solid credit profile but OpenAI is very weak. It's a startup with significant AI innovation risk and lots of competition"1

3

. Amir Anvarzadeh of Asymmetric Advisors cautioned that "if Arm's valuation drops, the value of the loan against it does not. A significant drop in the price of its assets could mean a liquidity squeeze"1

. Competition from cheaper Chinese AI models may spark a price war, potentially hitting the margins of frontier developers such as OpenAI as well as demand for semiconductors powering them1
