Morgan Stanley: 800V Power Delay Overblown, OCP Summit May Catalyze Semiconductor Stocks
nashnova research
Morgan Stanley says the market panic over Nvidia's 800V DC power delay has gone too far — related semiconductor stocks have given back all valuation gains, yet consensus revenue forecasts have actually risen 27%, and the upcoming OCP summit could trigger a re-rating.
What exactly got delayed on 800V?
Nvidia originally planned to introduce native 800V power delivery in its Rubin Ultra rack via the Kyber cabinet architecture in H2 2027. That plan has been shelved — Kyber is no longer the cabinet form factor for Rubin Ultra.
This means → the first truly native 800V rack now likely arrives with the next-generation Feynman architecture, rated at roughly 1 megawatt, around 2028.
In plain terms = what slipped is the "full-rack native 800V" step, not the broader power transition. The 800V Sidecar — an external power module that sits alongside the rack — is already shipping on schedule, and Nvidia's centralized Power Center system remains on track for 2027.
Valuations gave it all back — but fundamentals kept climbing?
After Nvidia unveiled its 800V roadmap at GTC in March, EV/Sales multiples — a measure of how much the market pays per dollar of revenue — for related stocks surged roughly 50%, peaking in mid-June before falling sharply on delay reports. The sector now trades at about 6.5×, essentially back to pre-GTC levels.
The Philadelphia Semiconductor Index's valuation premium over the 800V cohort widened from 12% to 25%, well above the 17% average since April. This means → the market is now discounting this group more harshly than the broader chip sector.
Yet fundamentals tell a different story: the cohort's forward-12-month revenue growth has risen from 12% to 27% since GTC. Since delay headlines first appeared, consensus revenue estimates have actually been revised up ~11% — not a single company saw a downgrade.
In plain terms = the stock price has already priced in the bad news, but the companies' earnings power is still accelerating. Morgan Stanley sees a clear disconnect.
Why does the OCP summit matter?
The 2026 OCP Global Summit — the annual conference where tech giants set open data-center standards — will host 364 technical sessions, up more than 30% from 267 in 2024.
Power and data-center infrastructure sessions nearly tripled versus 2024, now accounting for roughly 16% of the full agenda. This reflects a sharp rise in industry-wide urgency around the power problem.
Nvidia, Google, Microsoft, and Meta will all participate. The market will focus on three things: whether the Sidecar program stays on schedule, the 2027 deployment plan for Power Center, and a concrete timeline for native 800V racks.
Which companies are in the path of this trend?
Morgan Stanley names Analog Devices (ADI), Texas Instruments (TI), onsemi, Wolfspeed, and Navitas Semiconductor (NVTS) as beneficiaries — all directly tied to power management and power semiconductors for AI data centers.
This means → whether native 800V racks land in 2027 or 2028, the underlying driver — relentlessly rising data-center power consumption — is unchanged. Demand for power-management chips does not hinge on any single deployment date.
Morgan Stanley also flags that strong AI-driven demand for analog chips — chips that handle continuous signals like voltage and current, as opposed to digital chips — could push mature-node wafer fab utilization toward tightness by 2027, with early signs of supply shortages already emerging for some products.
