Wall Street Banks Lobby for Investment-Grade Credit Ratings for OpenAI and Anthropic Ahead of IPOs

Anthropic could publicly file its IPO prospectus as early as the following week, begin its roadshow by late September and potentially start trading in New York in late September or early October.
Morgan Stanley was reportedly the frontrunner to become Anthropic’s lead-left bookrunner, while Goldman Sachs was expected to act as stabilization agent; JPMorgan, Citigroup and Barclays were also expected to receive major underwriting roles.
A senior credit analyst said the banks were seeking to reduce concerns about the companies’ debt burden by emphasizing that the IPOs would give OpenAI and Anthropic “ample liquidity.”
Under traditional credit measures, both companies are viewed as closer to speculative-grade borrowers because they lack established, consistently positive free cash flow while continuing to require major spending on model training and data-center construction.
The financing push is part of a broader, interconnected AI infrastructure ecosystem: Nvidia, Oracle, Google and Broadcom could benefit if OpenAI and Anthropic gain access to cheaper debt and continue expanding their purchases of chips, cloud capacity and data-center services.
Morgan Stanley and Goldman Sachs are pushing credit rating agencies to award investment-grade ratings to OpenAI and Anthropic after their planned IPOs. The move would unlock roughly $11.7 trillion in corporate bond markets, letting the still-unprofitable AI giants borrow money more cheaply. TipRanks reports the banks argue IPO cash would strengthen both companies' balance sheets and liquidity.
Both companies face steep odds. OpenAI and Anthropic ran combined operating losses while burning through billions on chip purchases, model training, and data centers. Credit analysts say they lack the positive free cash flow needed for investment-grade status under traditional measures. Yet banks believe the IPOs could change that math by pouring new capital into their coffers.
Morgan Stanley is reportedly the frontrunner to lead Anthropic's IPO, with Goldman Sachs acting as stabilization agent. The Banker notes JPMorgan, Citigroup, and Barclays are also expected to receive major underwriting roles. This coordinated push suggests the banks see big stakes in getting these companies rated as safer borrowers before their public debuts.
The banks' strategy centers on emphasizing post-IPO liquidity. A senior credit analyst told Semafor the pitch emphasizes how IPO proceeds would give OpenAI and Anthropic 'ample liquidity' to service debt. This framing attempts to sidestep concerns about the companies' massive ongoing infrastructure costs.
Investment-grade ratings lower borrowing costs dramatically. For companies spending tens of billions annually on Nvidia chips and data centers, cheaper debt translates into hundreds of millions in savings. Yahoo Finance reports this cost reduction could fund years of model development and infrastructure expansion at both firms.
The catch: both companies currently fail traditional credit tests. GuruFocus notes OpenAI and Anthropic lack consistent positive free cash flow while continuing massive spending on computing power. Under normal standards, they'd be rated as speculative-grade—the riskier category that demands higher interest rates.
Anthropic could file its IPO prospectus by late August 2026 and begin its roadshow by late September, according to The Banker. Trading could start in New York by late September or early October. These dates explain the urgency: the banks need credit ratings approved before shares hit the market.
Success here ripples across the tech ecosystem. GuruFocus highlights that Nvidia, Oracle, Google, and Broadcom all stand to gain if OpenAI and Anthropic access cheaper debt and expand their infrastructure spending. Cheaper financing for AI giants means bigger orders for semiconductor and cloud suppliers, creating a virtuous circle for the entire sector.
