Broadcom's Hock Tan: capital, not chips, is AI's next bottleneck

Broadcom chief executive Hock Tan said on 12 October that capital, not chips, memory or power, may become the biggest constraint on the AI build-out. He put the wafer squeeze easing by 2028 and sized a gigawatt at about $10bn a year of cost against about $30bn of frontier-lab revenue.

Broadcom chief executive Hock Tan said on 12 October 2026 that capital, not chips, memory or power, may become the biggest constraint on the AI build-out. Speaking on a panel with Intel chief executive Lip-Bu Tan at DBS's Asia Future Forward Conference, he said the wafer squeeze should ease by 2028, memory could look very different a year from now, and demand for compute should still outrun supply into 2029, probably 2030. On the semiconductors layer, that is the largest custom-chip seller telling buyers the stuck step is moving off the fab and onto the balance sheet.

What happened

12 October 2026 · DBS Asia Future Forward Conference

"I think might be the biggest constraint is capital"

Hock Tan, agreeing with the moderator's point on rising hyperscaler borrowing costs after a jump in long bond yields

Supply clock

Wafer squeeze eases by 2028; memory may not be short a year out

CNBC quoted him on wafers easing by 2028 or 2029, with power there for anyone planning for 2028 or 2029

The per-gigawatt split (his numbers)

About $30bn of lab revenue per GW; about $10bn a year to build and run it

Anthropic at about $65bn annualised revenue on under 2.5 GW. "The $10bn, of course, is what we all fight over"

Token economics (his estimate)

About $200bn a year spent making tokens, about $150bn earned back

Frontier labs roughly $100bn in, $120bn out. Open-weight models spend about the same and get about $30bn back


Why cash cares

For two years the stuck step on this map has been physical: wafers, packaging, HBM, then power. Tan's claim is that each of those gets solved on a known clock, and the next limit is who will fund the halls before the revenue arrives. That matters for the chip sellers because they sit inside his "$10bn a gigawatt" slice. Broadcom, Nvidia, the memory makers (Samsung, SK hynix, Micron) and the foundry get paid from that slice, and only when someone writes the cheque for the racks.

His own numbers show who can carry the coupon. A frontier lab earning about $30bn per gigawatt against about $10bn of yearly cost keeps roughly $20bn, so in his words the labs "can afford to pay whatever coupons you like to charge." The open-weight camp, losing about $70bn a year on his estimate, cannot. Enterprises buying tokens without a return, which he said is most of them, sit further back still.

Our arithmetic, not a company figure. Under 2.5 GW at about $10bn a GW a year puts under $25bn a year of Anthropic's spend in the pool that chips, memory, networking and halls share. That is the cash Broadcom's custom-chip business is chasing, and it is why the financing behind those racks, such as the $60B AI-chip package Broadcom's banks began gathering on 2 October, is now part of the chip story.

Hock Tan's per-gigawatt split and supply clock

Figure: The bind moves to money. Revenue and cost per gigawatt as Hock Tan stated them, with his supply clock. The under-$25bn pool is our arithmetic.

The second-order read

Who gets paid. Chip, memory and foundry sellers, as long as frontier labs keep earning and lenders keep funding. Tan's split says the lab, not the vendor, keeps most of the value per gigawatt.

Who waits. Buyers that need debt and lack frontier-lab revenue: open-weight model builders, enterprise projects still looking for a return, and build-outs whose financing is not closed.

Who carries the risk. Lenders and landlords funding halls ahead of revenue, more so if long bond yields keep rising. Tan said demand could slow if adoption disappoints or models stop getting much better.

Stuck step. Signed, funded orders. A wafer slot freed up in 2028 does not pay anyone if the buyer cannot raise the money for the rack.

Two cautions

These are a chief executive's on-stage estimates, not filed figures. The $200bn token spend, the $30bn-per-GW revenue and the $10bn-per-GW cost are his numbers, built partly on OpenRouter usage data.

Chip shares fell on 13 October: Samsung and SK hynix each dropped more than 7% in Seoul and ASML more than 3% in Amsterdam. Reports tied the sell-off to both the financing warnings and ChangXin Memory's claim of a denser DRAM cell, so do not read it as a verdict on Tan's remarks alone.

What would change the view

  • Chip makers' Q3 order books showing buyers cancelling or pushing out for funding reasons, not supply.
  • The $60B Broadcom-linked financing closing, or stalling, at syndication.
  • Frontier-lab revenue growth slowing enough to dent Tan's $30bn-per-GW figure.

What to watch

  • TSMC's Q3 results on 15 October: whether the packaging and advanced-node commentary still reads as supply-bound.
  • Debt costs for hyperscalers and labs: long bond yields were the trigger for the question on stage.
  • Memory pricing into 2027: Tan's "a year from now" line is a direct test of how long the HBM squeeze lasts.
