Broadcom Shares Climb 3% Following DA Davidson Upgrade and Anthropic IPO Filing

Broadcom shares rose by 3% in early trading to reach $339.90 following a fresh analyst upgrade from DA Davidson that increased the company's price target to $400. The market movement is tied to Anthropic's newly public initial public offering filing, which highlights Broadcom's close connection to the artificial intelligence lab's compute expansion. Other semiconductor stocks also moved higher during the session, with NVIDIA shares advancing 1% to $218.41, AMD shares rising 2% to $544, and the iShares Semiconductor ETF increasing by 2%. Meanwhile, large-cap tech lagged behind these gains, as shown by a 0.6% increase in the Invesco QQQ Trust.

DA Davidson upgraded Broadcom stock from Neutral to Buy, reasoning that Anthropic's IPO registration signals continued momentum in the artificial intelligence spending cycle. According to the public filing, Broadcom serves as both a supplier and a lessor of artificial intelligence computing equipment to Anthropic through non-cancelable five-year leases. These agreements provide Anthropic with compute capacity utilizing tensor processing units, with portions scheduled to come online in 2026 and 2027. Furthermore, Anthropic deposited cash into a restricted account for Broadcom's benefit in April to secure this compute capacity.

Broadcom's business model relies heavily on custom artificial intelligence accelerators designed for a small group of large customers, contrasted with NVIDIA and AMD which serve broader customer bases. In the third quarter of fiscal year 2026, Broadcom reported artificial intelligence semiconductor revenue of $16.7 billion, representing a 221% year-over-year increase, with a fourth-quarter outlook projecting $21.7 billion. During a September earnings call, Broadcom indicated that Anthropic is positioned to become its largest custom accelerator customer by 2027. However, analysts note that Broadcom's growth remains tied to customers whose funding depends on successful capital raises, and lease obligations can accelerate if payment or performance defaults occur.
