Credo's leading AEC position and vertical integration keep its optics thesis bullish despite SpaceX moving away from 1.6T AECs. That shift is a genuine risk, but xAI has been in Credo's AEC ecosystem the longest, which could support ZeroFlap optics and its telemetry software. Credo's VCSEL-based ALCs were still ramping toward 2027, giving it another route as customers move to transceivers. x.com  x.com  x.com 

Unlocking Samsung production capacity would give MaxLinear a real edge in the capacity-constrained active electrical cable market. CEO Kishore Seendripu outlined an ambition for 20-30% share of the 1.6 Tbps AEC generation over the next couple of years, initially targeting one or two major US data-center customers and challenging dominant incumbent Credo Technology. x.com 

MaxLinear's 1.6T roadmap threatens Credo's dominant AEC position with a specific share target. MaxLinear targets 20–30% of the 1.6T active electrical cable cycle, where its management estimates Credo has 93–99% share, initially across 1–2 US data centers. MaxLinear also reports 1.6T DSP and TIA design-win commitments, with initial revenue expected in 2027 and a stronger ramp in 2028. That competitive concern is behind Credo's pre-market drop. x.com 

Credo's first 1.6T active linear cable uses micro-VCSEL instead of microLED, putting the preferred optical technology into that product. Credo has finally acknowledged the pivot, and micro-VCSEL remains the much-favored approach. x.com  x.com  x.com 

Credo has fallen over 40% since early July even as its microLED cable story improved, and that gap is the opportunity. On the September 1 call, CEO Bill Brennan said its microLED active cables reach 30 meters, carrying copper-like reliability and power beyond the rack, and called it just step 1 toward scale-up. Published data already works around the dispersion physics skeptics cite. The open question is production cost, set by fiber bundles and equalizers. First revenue is still in fiscal 2028. … Show more

Credo looks exposed as networking becomes AI's next bottleneck and Nvidia locks down optical fiber for scale-up, scale-out and scale-across links. MicroLED is readily available and a good contender for scale-up and potentially scale-out, with many Asian suppliers pivoting into it. x.com  x.com 

Credo solves AI clusters' biggest pain points, network reliability and power consumption, and is now adding a second growth curve in optics. Its active electrical cables deliver 1,000x the link reliability of optical transceivers at lower power and cost, critical as clusters scale to millions of GPUs. With DustPhotonics closed, management expects ZeroFlap optics, silicon photonics chips and optical DSPs each to exceed $100 million in FY2027 revenue, taking optics past $600 million. x.com 

MicroLED's poor prospects and growing expert enthusiasm for VCSEL could put ams OSRAM on more investors' radars. An ams OSRAM optical-interconnect executive says a 1.6T active linear cable was demonstrated using the company's micro-emitter engine with Credo's help, and their short-reach micro-optics partnership continues. x.com  x.com  x.com 

Credo is a trade rather than a long-term hold because co-packaged optics is the technology that closes the copper-to-optics gap its retimers and active electrical cables fill. If CPO ramps faster than expected in the 2027 architecture cycle, those products get designed out. That is not a 2026 problem, but it is why a decelerating hyper-growth chipmaker can't keep a 15x sales multiple forever. Customer concentration, which hit the stock before, adds risk, and Credo fits no AI endgame theme. x.com  … Show more

Credo's gradual optics ramp is the reason to own it, though that ramp will be lumpier than general research suggests. Its purple active electrical cables appear in newly released footage of Meta's Prometheus training cluster, and it already has a strong base in copper. x.com
