🔥 $NVIDIA(NVDA.US) has given a $78 billion guidance, but what's truly undervalued is the entire "neglected AI downstream chain."

The market's first reaction only focused on one number:

$NVIDIA(NVDA.US) FY27 Q1 guidance of $78 billion, $5.4 billion higher than Wall Street expectations.

This is certainly important, but the real key isn't here.

The deeper signal is actually hidden in the structure, not the headline.

Last quarter, network-related revenue doubled year-over-year.

What does this mean?

This isn't GPU demand itself; it's the "connectivity layer" within data centers starting to explode.

Computing power is no longer the bottleneck; connecting that power is.

When the number of GPUs grows exponentially, data must be transmitted faster and more stably, otherwise computing power is wasted.

This directly transfers demand to another group of companies:

$Arista Networks(ANET.US)

$Broadcom(AVGO.US)

$Credo Tech(CRDO.US)

$Astera Labs(ALAB.US)

What these companies do isn't "computing power," but the infrastructure that actually allows computing power to run.

The problem is, the market is still looking at things through the old framework of "NVDA driving AI."

But the reality has become:

NVDA → triggers demand

Networks / Optical modules / Connectivity → are the amplifier

The bigger variable is actually capital expenditure.

Hyperscale cloud providers have made it clear:

2026 CapEx will exceed $650 billion.

This isn't a quarterly trading logic; this is a structural investment cycle.

Money won't just stay with GPUs.

It will flow through the entire chain:

Power

Cooling

Optics

High-speed Connectivity

This is the most easily underestimated part.

Because these companies don't have the "AI halo," but they are eating from the same wave of dividends.

And there's an even more important detail:

The bottleneck nature of these segments is strengthening.

After GPU supply increases, whoever constrains performance will have pricing power.

This is why networks and optics are starting to see "demand jumps."

The market's problem is—

Most people are only trading "what's already risen," not "the segments that haven't been re-priced yet."

If the logic holds, then the current situation is more like:

NVDA has already priced in part of the future

But the downstream chain is still stuck in the old valuation framework

The mismatch in between is essentially the opportunity.

But there's also a point to be wary of here:

This type of opportunity isn't a short-term explosion, but a gradual realization as CapEx unfolds.

In other words, it's more like a "structural trend," not an emotion-driven pump.

The real question becomes:

When the market is all watching $NVIDIA(NVDA.US),

Do you keep chasing the most crowded core,

Or start positioning in those segments the market doesn't fully understand yet?
