Credo Technology Group Holding Ltd (Nasdaq: CRDO) builds connectivity silicon and cables for AI data centers, including the purple ZeroFlap active electrical cables (AECs) used on short copper runs. Deep Sail Capital (@DeepSailCapital), a long/short growth and microcap investor on X, asked whether Lumentum's admission that it can supply only about 30% of optical demand is "super bullish" for Credo because AECs can take more of the workload where they still work. The stock was already a crowded AI-infrastructure name near $217 on October 9, 2026, so the debate is less "whether AI needs interconnect" and more "whether copper wins share when lasers are scarce."

Key facts
- Ticker and exchange: Credo Technology Group Holding Ltd, CRDO, Nasdaq.
- Situation type: AI interconnect beneficiary; copper AECs versus constrained optical lasers.
- The call: Deep Sail Capital leaned long CRDO after quoting a Lumentum CEO clip that optical supply covers only ~30% of asked demand into 2027.
- Price: CRDO closed at $216.55 on October 9, 2026 (call price in our log for the October 9 post was $211.86 on the prior close basis).
- Catalyst quote: Shay Boloor (@StockSavvyShay) highlighted Lumentum CEO Michael Hurlston saying the company "can only supply 30% of what we are being asked to supply."
- Product news: Credo separately unveiled a 1.6T ZeroFlap Active Light Cable aimed at longer row-scale links, with shipping targeted in 2027, extending the story beyond pure copper.
- Main risks: Rich valuation after a large run, optical alternatives catching up, customer concentration, and a broad AI-hardware drawdown (CRDO appeared on several October 12 "AI dip" lists).
Is CRDO a good bet right now?
That depends on whether scarce electro-absorption modulated lasers truly push incremental dollars to Credo's AECs at distances where copper still reaches, and whether today's multiple already discounts that share shift.
The bull case is a physical bottleneck: if optics cannot ship, short-reach copper remains the practical path inside racks and between nearby switches. The bear case is that Credo is priced for perfection while it also spends to build its own optical stack, which can compete with the very scarcity thesis.
Why are investors bullish on Credo?
- Deep Sail linked Lumentum scarcity to AEC demand. On October 9, 2026, Deep Sail Capital wrote, "Isn't this super bullish $CRDO because it means $LITE can't supply a lot of the demand with optical, thus AECs likely see a larger demand in cases where they work?"
- The source clip is specific. Shay Boloor posted the Lumentum CEO line about supplying only 30% of asked optical demand as CPO/NPO laser needs accelerate.
- Credo keeps extending the interconnect map. Babyfolio summarized Credo's 1.6T ZeroFlap Active Light Cable: up to 50 meters of reach, lower power than comparable AECs, shipping expected in 2027.
Who's making this call and why?
Deep Sail Capital (@DeepSailCapital) is a quality/growth and microcap long-short account with about 57,300 followers on X. The CRDO post is a reaction to an optical-supply bottleneck rather than a full initiation write-up, which matters for how tightly the thesis is stated.
Track record. In our tracking of Deep Sail Capital's public calls, the account is 13-12 (a .520 win rate) on 25 calls scored at 180 days against the S&P 500, with an average edge of +8.9 percentage points. Twelve newer calls are 9-3 on a provisional basis.
Other supporters:
- @StockSavvyShay supplied the Lumentum 30% supply clip that Deep Sail quoted (October 9, 2026).
- @Babyfolio framed the new Active Light Cable as Credo extending its copper reliability playbook into longer optical reach (October 12, 2026).
Who disagrees?
- Valuation and drawdown risk. On October 12, 2026, several market accounts put CRDO on AI pullback lists after a roughly 6% to 7% decline that day, treating it as a crowded high-beta semiconductor rather than a special situation.
- Optics catching up. If Coherent and others close the EML gap, or if Credo's own optical products cannibalize AEC share, the "copper wins because lasers are scarce" line weakens.
- Execution and customer risk. AI cluster designs can shift among copper, pluggable optics, and co-packaged optics faster than a single cable generation.
What are the key facts to verify?
- Whether Lumentum's "30%" remark is about EML lasers broadly or a narrower product slice, and how long the shortage lasts.
- Credo AEC revenue mix versus optical DSP, transceiver, and future Active Light Cable contribution.
- Reach limits where AECs still displace optics (typically single-digit meters today) versus the 50-meter ALC roadmap.
- Valuation versus peers after the October 9 close near $217.
- Customer concentration among hyperscalers and switch vendors.
What would prove it right or wrong?
Signals the call is working:
- AEC shipments and guide rising as optical lead times stay stretched.
- Hyperscaler designs keeping copper in the short-reach bill of materials.
- Optical scarcity commentary from multiple laser vendors, not one clip.
Signals it is failing:
- Laser supply normalizes and copper share stalls.
- CRDO multiple compresses faster than fundamentals grow in an AI hardware selloff.
- Credo's optical roadmap fails to land while AEC growth slows.
