Broadcom's AI Surge Faces a Lone Voice of Valuation Caution

Broadcom shares surge as AI deals with Google & Anthropic fuel revenue forecasts above $130B. Analysts remain bullish despite overbought RSI and one valuation-driven downgrade.

Shares of Broadcom have been on a tear, fueled by a series of billion-dollar artificial intelligence infrastructure deals. The stock gained over 6% on Tuesday and added another 4.25% on Wednesday to trade around 298 euros, bringing its twelve-month advance to approximately 108%. This rally has pushed the Relative Strength Index (RSI) to a level near 82, indicating the stock is deeply in overbought territory.

The catalyst for this week's surge is a significant expansion of the company's strategic partnerships. Broadcom has secured agreements to design future generations of Google's Tensor Processing Units (TPUs) and networking components through 2031. In a separate three-way deal, AI startup Anthropic will gain access to massive computing capacity, which is projected to scale to 3.5 gigawatts by 2027.

These deals build on an already formidable financial performance. For the first quarter of its 2026 fiscal year, Broadcom reported AI-specific revenue of $8.4 billion, a 106% year-over-year increase. This momentum has led Wall Street to ratchet up its expectations. Analysts at Mizuho forecast AI revenue from Anthropic alone could reach $21 billion this year, potentially doubling to $42 billion in 2027. Looking further out, Citi analysts see Broadcom's total revenue climbing to over $130 billion, well above the company's own $100 billion target for fiscal 2027.

Amid this widespread optimism, a single analyst at Seaport Research, Jay Goldberg, has bucked the trend by downgrading the stock from Buy to Neutral. His caution stems not from the operational strength but from valuation and structural pressures. Goldberg argues that Broadcom, alongside peers like Nvidia and AMD, faces a capital-intensive reality where building gigawatt-scale data centers is drawing chip suppliers into customer financing. He also noted a potential risk that Taiwan's MediaTek could take over a portion of Google's TPU business later this year, which might increase Google's bargaining power.

Goldberg's stance places him in a distinct minority. The broader analyst consensus, comprising 29 firms, remains a "Strong Buy" with an average price target of $438. Firms including Mizuho, Bank of America Securities, Rosenblatt, and Jefferies have all recently reaffirmed their Buy ratings with targets ranging from $450 to $500.

Concurrently, Broadcom is advancing its enterprise software division. The company unveiled the "Arcot Smart Ruleset," an AI-powered engine for payment fraud prevention. This system uses machine learning models trained on 20 years of transaction data from over 5,500 financial institutions to replace manually maintained rules. Early adopter Velera reported the technology helped prevent over $2 million in additional fraud losses in the past six months.

Supporting its ambitious growth strategy, Broadcom is also making a key leadership change. In June 2026, Amie Thuener, a veteran of Alphabet since 2018, will take over as Chief Financial Officer. She succeeds Kirsten Spears, who is retiring after twelve years. This appointment further deepens the company's ties with major AI industry players.

For the current second fiscal quarter, Broadcom's management has guided for total revenue of approximately $22 billion. As the company navigates its path toward unprecedented revenue levels, the market must weigh its spectacular operational execution against the mounting questions of valuation raised by a solitary skeptic.
