OpenAI拟以约1.4万亿美元估值融资约300亿美元，软银等出资方CDS走阔引发AI资本开支信用担忧

Prediction market odds of OpenAI ( OPENAI ) achieving a $1.25T valuation by Dec. 31 surged 20 percentage points to 85% following a report Tuesday of a massive new capital injection . The spike on Polymarket comes as OpenAI ( OPENAI ) races to finalize around $30B in fresh investor commitments at an estimated $1.4T valuation . The compressed timeline is intended to lock in commitments ahead of rival Anthropic’s ( ANTHRO ) anticipated mid-November initial public offering, as the two leading AI developers vie for a largely overlapping pool of institutional capital . Existing backers, including Abu Dhabi’s MGX and SoftBank Group ( SFTBY ) ( SFTBF ), are in talks to anchor the financing . While the fundraising has solidified OpenAI’s ( OPENAI ) towering valuation benchmarks, it has rattled debt markets regarding SoftBank's ( SFTBY ) expanding exposure . SoftBank’s credit default swaps surged 12 basis points overnight to 432—hitting a fresh four-year high as markets absorb the potential capital demands, according to Zerohedge. The pressure on SoftBank ( SFTBY ) mirrors a broader wave of credit jitters sweeping the tech sector as hyperscalers lean heavily on debt to fund historic AI infrastructure budgets . Five-year default protection costs on Meta ( META ) and Nvidia ( NVDA ) have both reportedly crossed above 100 basis points to fresh highs, while CDS spreads for Amazon ( AMZN ), Alphabet ( GOOG ) ( GOOGL ), and Microsoft ( MSFT ) have climbed near or past the North American investment-grade benchmark—underscoring growing Wall Street skepticism toward the sustainability of the AI capex boom .
