Microsoft (MSFT) Lands Citi's High-Conviction Call as CoreWeave Bond Yields Near 15%

Bond Market Sets the AI Funding Terms

A sell-side research call put the debt side of AI infrastructure under scrutiny this week. Tyler Radke, co-head of US software research at Citi, said in a CNBC interview that the bond market, rather than end demand for compute, is steering the current selloff in neocloud stocks. In his words, the bond market “controls this narrative” at present. Neoclouds rent Nvidia's H100 chips to AI developers, frequently on borrowed money. Radke noted that rental rates for those chips sit near record levels, yet CoreWeave's bonds yield close to 15%. The gap between what the hardware earns and what the debt costs sits at the center of his argument. He does not read the selloff as a verdict on demand for AI compute.

The rate backdrop explains part of it. The 10-year Treasury yield has climbed roughly 30% from its March low, a move that lands hardest on borrowers without investment-grade credit ratings, in Radke's reading. That squeeze is hitting a market already absorbing a heavy load of AI-related debt. The pressure surfaced in equities last week: CoreWeave stock dropped 15% in a single session, and Oracle, which has also borrowed to build data centers, closed 8.8% lower the same day. Venture capitalist Chamath Palihapitiya published a chart of CoreWeave's bond yields on X as the shares sold off on Friday, October 16. Radke expects the higher funding costs to end up in customer pricing. Neoclouds will pass elevated borrowing costs into the rates they charge on future contracts, in his assessment, which means companies financing data centers with lower-grade debt either reprice their deals or accept thinner margins. He framed the current setup as a question of who holds pricing power. Until customers accept higher contract prices, the bond investors funding AI infrastructure set the terms.

Software Margins Over Borrowed Chips

The case for software rests on cash generation rather than leverage. Radke points to the margin and cash flow profiles of Microsoft and Palantir, the data analytics software firm, and singles out Microsoft as among his highest-conviction ideas in the space. Microsoft, in his description, generates positive free cash flow even with heavy annual capital spending and does not depend on debt markets. Owning the shares, he argues, demands no opinion on how fast AI chips depreciate or on how the company funds itself. That distinction matters because chip-heavy neoclouds carry both sides of a hard equation: servicing costs that rise with rates and hardware that loses value on a fixed schedule. A debt-funded chip renter faces that depreciation clock with interest bills attached, which is where the 15% yield becomes an economic constraint rather than a market footnote.

Radke does not present the call as either-or. Software has trailed chip stocks through the whole AI boom, in his framing, and both exposures can sit side by side in a portfolio. His Microsoft preference is a conviction ranking, not a forecast that hardware exposure collapses.

The call puts him on the other side of a better-known voice. Tom Lee issued a buy recommendation after Friday's selloff, naming neoclouds and chip stocks as his preferred entries. Lee's case assumes the drawdown was technical and that demand stays intact; Radke's assumes financing costs now govern the sector's economics, whatever demand does.

Two counterpoints sit around Radke's caution. CoreWeave has said its contracted backlog is big enough to cover every dollar of its debt, a company statement aimed at the bond-yield alarms. Gartner, the research firm, separately forecasts that four in five neoclouds will lose their independence by 2030. Those two points pull in opposite directions on the question his software thesis rests on: whether neocloud customers will accept the higher contract prices now in prospect.

MSFT Sideways at $535.56

The rate thesis leaves the software name itself in a holding pattern rather than a trend. COINOTAG data shows Microsoft (MSFT) trading at $535.56, up 0.33% over 24 hours, inside a $527.30 to $536.37 range. Our composite scores the nearest support, $530.34, at 81/100 and first resistance, $539.10, at 65/100; both levels are built from moving-average bands, Fibonacci retracement tiers and pivot calculations. Momentum is mixed: the daily RSI sits at 59.9, the MACD signal is bearish, and the daily trend reads sideways. Perpetual open interest in the name stands near $33.5 million. A daily close under the $530.34 floor, or an advance through $539.10, is what would change that picture. For now the shares sit mid-range, above scored support, in a sideways trend.
