Nvidia Q1 Looms as AI Rally Hits Mid-Week Test

Nvidia reports Q1 FY2027 earnings after the bell on May 20. Management has guided $78B in revenue (±2%), Street consensus has nudged up to roughly $78.5B, and the EPS consensus sits at about $1.77 — already a touch above the guide. The print on its own does not have much room to surprise on the upside.

What the AI rally is actually testing this week is three lines that ship alongside the print: the Q2 guide, the Blackwell inference monetization commentary, and the Rubin rollout cadence. With FOMC minutes landing in the same week, every line on Wednesday's call gets read louder than usual.

The Flow Was Already Set Last Quarter

To see where the guide came from, look at the prior print. Q4 FY26 dropped on Feb 25 and the market reset the model that same day.

Datacenter revenue was $62.3B, up 75% year-on-year and 22% quarter-on-quarter — a single quarter pulled the line up by roughly $11B. The $78B Q1 guide assumes that acceleration just keeps going.

On that call Jensen Huang called out 'Grace Blackwell with NVLink is the king of inference today.' That single sentence shifted the read on Blackwell from 'still ramping' to 'in monetization mode,' which is why consensus has crept up above the guide.

What the Four Hyperscalers Plan to Spend in 2026

If one end of the line is the Nvidia guide, the other end is the capex line from the four largest hyperscalers. The real floor under Q1 guidance is what those four plan to spend in calendar 2026.

Microsoft has guided roughly $190B for 2026 and spent $31.9B in Q3 alone, with Q4 capex expected to push past $40B. Meta raised its 2026 capex range from $115B–$135B to $125B–$145B at its May Q1 print. Amazon did not refresh a full-year guide in Q1, but trailing-twelve-month PP&E purchases net of incentives now sit at $147.3B, almost entirely AI infrastructure. Alphabet still holds its $175B–$185B range.

Add the four together and 2026 will move north of $700B into AI and datacenter buildouts. A guide raise from any one of them lifts Nvidia's next two quarterly estimates with it. S&P Global's Q1 FY27 preview lands on the same capex anchor.

Blackwell Now, Rubin Next

Product roadmap commentary lands as heavily as the capex line. The market is watching how Blackwell and Rubin get framed in the same call.

Blackwell is already shipping in volume. After the 'king of inference' line on Q4, the read on Blackwell has shifted to how fast it converts into inference revenue specifically. Any extra color on inference mix or the training-versus-inference split this week becomes the headline quote of the week.

Next card is Rubin. The Vera Rubin platform was unveiled at CES 2026 on Jan 5, with a six-chip family. The flagship Vera Rubin NVL72 rack pairs 72 Rubin GPUs with 36 Vera CPUs, glued together by NVLink 6, ConnectX-9, and BlueField-4. A single Rubin GPU is rated at 50 PFLOPS at NVFP4 precision and 3.6 TB/s of memory bandwidth. The named early-adopter list spans AWS, Google Cloud, Microsoft, OCI, CoreWeave, Lambda, Nebius, and Nscale on the cloud side, plus Anthropic, Meta, OpenAI, xAI, Runway, Cursor, and Magic on the AI lab side. Rubin Ultra systems are slated for the second half of 2027, so the call's tone on Rubin versus Rubin Ultra resets the 2027 model in the same breath.

FOMC, the Gulf, and the Bubble Debate Share the Stage

If this print were a single-stock story the trade would hang on one line of guidance. It is not. The same week ships May FOMC minutes, fresh drone activity in the Gulf is pushing oil and bond yields back into the picture, and the dollar index is moving alongside.

With the multiple back above 50x and the bubble-versus-justified-growth fight at full volume, the single line on the Q2 guide sets the entryway for the June and July tape. The bull camp has pull-quotes ready on 'Blackwell inference acceleration plus Meta/MS capex raises'; the bear camp is waiting to clip 'hyperscaler capex peak + 2027 deceleration risk.'

A short press release after Wednesday's close and the 30–40 minute call that follows will set the AI tape for the entire week. The pattern is close to last week's I/O 2026 pre-keynote leak roundup — a single event resetting the trade for days.
