Broadcom (AVGO) shares moved higher in extended trading on Tuesday, rising 2.20% to $339.30 after the closing bell, as the chipmaker secured a place among the buyers in Anthropic's $26 billion private placement and semiconductor stocks built on a rebound from the steep losses that opened the month.

The regular session was strong as well. Broadcom finished up 3.91% at $331.98, based on Benzinga Pro data. Earlier in the day, shares were up 2.69% at $328.08 around 9:53 a.m. ET. The advance came on the heels of an 8.78% jump on Monday, which had already signaled a shift in momentum for the sector.

Anthropic Filing Puts Broadcom on the Buyer List

The other major headline came from Anthropic. An amended filing named Broadcom as a buyer of roughly $1 billion in a $26 billion private placement. Broadcom joins Google, Nvidia, AMD, Micron, Microsoft and TSMC in the round. The group is purchasing nonvoting Class N shares at the IPO price, which is set at $70 to $78 — a structure that gives each participant a financial stake without voting rights.

Google and Nvidia are the largest participants at $10.0 billion each, followed by AMD at $2.5 billion. Broadcom, Micron and Microsoft are each committing $1.0 billion, while TSMC is taking $500 million.

The lineup spans much of the AI compute supply chain, from memory and chip manufacturing to accelerator design and the cloud platforms that deploy the silicon — meaning the companies that supply the hardware behind AI systems are also taking direct equity stakes in the model developer itself.

Measured against Broadcom's market value of roughly $1.53 trillion, the $1 billion commitment represents about 0.07%, so the stake remains small in dollar terms even as it places the company alongside some of the industry's biggest names.

The breakdown was detailed in an update shared by Wall St Engine on X:

Chip stocks had a rough start to the month. The Philadelphia semiconductor index, a widely followed benchmark for the industry, lost over 12% in one session on Nov. 5, deepening the pressure across the sector. Monday's rebound then added more than $200 billion in combined market value to AMD and Broadcom, and Tuesday's gains kept the bounce going.

JPMorgan analyst Harlan Sur also weighed in on the news. He said Google's newly announced TPU 8i Max fits within Broadcom's custom chip roadmap, and he kept his Overweight rating on the stock. Google, however, did not name Broadcom as a supplier, leaving the chipmaker's exact role in the TPU program an open question heading into its next scheduled update.

Broadcom has also set a date for its next report. The company will post fourth-quarter and fiscal 2026 results on Dec. 9, after the market close — its first earnings release since the Anthropic placement was disclosed. A conference call is scheduled for 2 p.m. Pacific Time the same day, during which management will discuss the results and the outlook.

Last Quarter and the Numbers Now

Broadcom heads into that report coming off a beat. In its last report, released in September, revenue came in at $29.59 billion, ahead of the $29.44 billion estimate. Earnings per share hit $3.32, versus the $3.16 analysts expected — a beat of 5.06%.

On the valuation side, Broadcom now has a market cap of $1.58 trillion. Its 52-week range runs from $289.77 to $495, leaving the stock well below its yearly high. Shares are down roughly 7.37% over the past 12 months and trade at 20.57% of their 52-week range, while the relative strength index (RSI) sits at 49.40, a level generally read as neutral. GuruFocus puts the GF Value at $447.22, which leaves the stock 26.64% below that mark.

The next test comes on Dec. 9, when Broadcom reports fiscal fourth-quarter results.
