Broadcom Q2 2026 earnings selloff on AI chip guidance

Broadcom didn't miss — it underdelivered on a price already paying for outperformance. The stock entered the print up 88% YoY at an all-time high of $479.23^[3], which means the multiple had been re-rated to absorb only one outcome: a raised guide. Instead, management reiterated the $100B+ FY2027 AI semiconductor target and guided Q3 AI revenue to roughly $16 billion versus a Visible Alpha consensus near $17.2 billion^[1][3]. A $1.2 billion gap on a 200%+ growth number is not a fundamental break — it is an expectations break. CFRA's Angelo Zino put it bluntly: "The bar was really high going into the print here, and I think part of the response"^[3]reflects that reset, not deteriorating demand. Bernstein's Stacy Rasgon reached the same conclusion from the opposite direction, noting that "forward AI guidance, rather than headline results, was the primary driver of stock decline"^[4].

The mechanics of the drawdown matter. AVGO shed roughly 12-15% in extended trading, erasing more than $300 billion in market cap^[5]. That move pulled the whole semiconductor complex down in sympathy — AMD, Intel and Qualcomm each fell 4%+, Micron and Super Micro about 7%, and even Nvidia gave back roughly 1%^[8][12]. The cross-asset reaction tells you what really changed: investors stopped treating Broadcom's guide as a company datapoint and started treating it as a hyperscaler-capex tell. If the most plugged-in custom-silicon vendor with six anchor customers can only see $16B in the next quarter, the implicit ceiling on AI infrastructure spend for the second half just got lower for everyone.

The single most consequential moment on the call was not a guidance number — it was a posture shift. Broadcom's AI franchise rests on six confirmed custom-XPU hyperscale customers, four of which are public: Google, Meta, OpenAI and Anthropic^[2][10]. Google has been the anchor. The April 2026 TPU supply agreement extending through 2031 was the deal that arguably re-rated the stock in the first place^[10]. So when management acknowledged on this call that Google would also be looking to diversify its chip-supplier base, that was the first concrete crack in the customer-concentration narrative that has carried AVGO's multiple. Anchor customers diversifying their silicon vendor base is normal hyperscaler hygiene; what's unusual is hearing it confirmed by the seller, on the record, in the same call where the forward guide didn't clear the bar.

That single admission reframes the bull case. Mizuho's standing estimate that Anthropic alone will deliver $21 billion of Broadcom AI revenue in 2026 and $42 billion in 2027^[11]works only if every anchor customer scales toward its committed deployment plan without redirecting share to in-house or competing designs. The deeper risk isn't that Google walks — it can't, the TPU stack is custom and the supply contract runs through 2031^[10]— it's that the incremental dollar of Google's next-generation AI capex no longer lands 100% at Broadcom. The market has spent twelve months pricing AVGO as the only credible custom-ASIC partner at scale. The call just gave bears a clean line to argue that the share-of-wallet story has a top.

JPMorgan's Harlan Sur asked the question that exposed why an in-line guide created a sharp drawdown: whether the 18-month backlog sits at $200 billion or better^[7]. The question is a back-solve. If Broadcom's reiterated $100B+ AI semiconductor revenue target for fiscal 2027^[2][9]is real, the 18-month visible commitment ought to be in the $200B vicinity — otherwise the implied second-half FY27 step-function is mechanically aggressive. Management did not give Sur that number. Instead, Hock Tan reached for a softer framing — that visibility runs into 2028^[6]. That is a confidence statement, not a reconciliation.

The reason this matters is that Q2 results actually under-supply the $100B trajectory rather than confirming it. Q2 AI revenue was $10.8B^[1], Q3 is guided to ~$16B^[1], which puts H1+Q3 around $30B. The exit-rate needed to clear $100B in FY27 implies a meaningfully higher Q4 and continued vertical acceleration through next year — exactly the trajectory a raised guide would have validated. By choosing reiteration over a raise, management told Wall Street one of two things: the customer ramp timing is too lumpy to underwrite quarter-by-quarter, or the conservative posture is itself the message. Either reading argues against paying a higher multiple. Sur's $200 billion backlog question was the entire bull case asking to be confirmed in a single number, and the absence of that number is what the price action wrote down.

On its own, the infrastructure software miss was small: $7.18 billion versus $7.32 billion expected, a $140 million shortfall^[4]. In a normal quarter that's a footnote. In this quarter it removed the diversified-compounder thesis on the same night the AI guide disappointed, which is why it matters. The bull narrative on Broadcom post-VMware^[4]has always been that the company is two engines bolted together — an AI semiconductor business growing triple digits and a software annuity throwing off cash to fund buybacks and a 30%+ FCF margin. When the AI engine guides in-line and the software engine misses in the same print, the implicit claim that one side smooths out the other gets dented.

The operating mechanics are still intact. Non-GAAP EPS of $2.44 (+54% YoY) beat consensus near $2.40, and free cash flow of $10.3 billion equaled 46% of revenue (+60% YoY)^[1]. Cash generation of that magnitude is not what a broken story looks like. What broke is the multiple, and the catalyst was the combination: a $1.2B AI guide gap plus a $140M software miss, in a stock that had run 88% YoY into the print^[3]. Both Bernstein^[4]and CFRA^[3]located the move in expectations rather than fundamentals. The next set-up to watch is whether the VMware integration drag becomes a recurring quarterly weight on the segment — if it does, the second engine of the AVGO thesis loses its smoothing function, and the AI story has to carry the entire valuation alone.
