TD Cowen reiterates Buy on Microsoft stock, cites OpenAI deal By Investing.com

TD Cowen reiterated a Buy rating and $540 price target on Microsoft, citing an amended OpenAI partnership that could reduce revenue-share payments by about $700 million in fiscal 2026 and $5.1 billion by fiscal 2030. The firm said the new structure may add 1% to 2% to Azure growth in fiscal 2027 and gives Microsoft more flexibility by ending its role as OpenAI’s primary inference provider. The update is constructive for Microsoft’s long-term AI economics, though near-term impact is likely modest ahead of earnings.

Analysis

The immediate market read-through is not just that MSFT’s economics improve, but that its operating leverage on AI becomes cleaner: lower pass-through costs and less infrastructure hostage risk should widen Azure’s incremental margin just as enterprise AI workloads move from experimentation to production. The bigger second-order effect is that Microsoft is no longer forced to be the single throat to choke for OpenAI growth, which reduces capex intensity and should lower the probability of a future cloud capacity overbuild cycle. That is bullish for MSFT quality-of-earnings and slightly bearish for the “winner-take-all” cloud narrative.

The competitive implication is more interesting for AMZN and ORCL than the headline suggests. If OpenAI is now structurally multi-homed across clouds, the bargaining power shifts away from any one provider and toward the infrastructure layer with the best marginal capacity, pricing, and deployment speed; that favors the hyperscalers with excess supply and punishes anyone relying on exclusivity economics. For MSFT, the trade-off is that reduced concentration risk likely compresses tail risk in earnings, but it also means less embedded optionality from owning the full stack, so the move is more defensive optimization than a new growth leg.

Consensus seems to be extrapolating the agreement into a durable acceleration for Azure, but the timing matters: the earnings benefit is likely modest near term and becomes meaningful only as OpenAI’s compute spend scales over several quarters. The key risk is that the market is already pricing AI infrastructure as a straight-line winner; if AI monetization lags compute expansion, cloud spend can decelerate faster than the partnership benefits accrue. The more contrarian setup is that this is mildly positive for MSFT but potentially even more positive for the diversified cloud beneficiaries that were previously excluded from the OpenAI relationship.

For the analysts and banks named, the real tell is that bullish revisions are now increasingly about ecosystem optionality rather than fundamental rerating. That tends to be a late-cycle signal for the trade unless actual revenue conversion from AI services re-accelerates into the next two quarters.

Key Decisions for Investors

• Stay long MSFT into earnings, but treat it as a low-volatility quality carry trade rather than a breakout catalyst; target a 1-2% upside surprise in Azure-related commentary with tight downside if management guides to slower AI revenue conversion.
• Pair trade: long AMZN / short MSFT for 1-3 months if you believe OpenAI multi-cloud spend will shift share toward the highest-capacity, most price-aggressive infrastructure provider; this is a relative-value trade, not a directional cloud bet.
• Consider long ORCL against a basket of mega-cap software names over the next 3-6 months if the market starts pricing incremental AI infrastructure demand from OpenAI-style workloads; Oracle’s leverage to external compute demand is higher, though the trade has execution risk.
• For event risk, sell upside calls on MSFT into earnings if implied volatility remains elevated; the stock’s reaction is likely to be muted unless Azure growth inflects materially, making short premium attractive on a 2-4 week horizon.
