Morgan Stanley has defended Broadcom against investor concerns about rising competition, calling it a core AI winner second only to Nvidia. The firm projects Broadcom will retain roughly 80% of Google's tensor processing unit business despite MediaTek's entry, dismissing bearish forecasts as premature. Broadcom shares have dropped 22% from their June peak despite recent chip deals with Apple, Meta, and Google.

Morgan Stanley Defends Broadcom Amid Investor Concerns Over Competition

Morgan Stanley has stepped up to defend Broadcom as investor concerns over competition from MediaTek have pressured the AI chip supplier's stock. In a note to clients on Tuesday, analysts at Morgan Stanley reiterated an Overweight rating on Broadcom, calling it "a core AI winner" and positioning it as a close second behind Nvidia in the AI hardware ecosystem

. Despite this endorsement, Broadcom shares are down almost 22% from their record closing high of $481.57 on June 2, with the stock rallying only about 14% year to date, significantly trailing the iShares Semiconductor ETF's nearly 90% gain

MediaTek's Role in Google's TPU Business Not Disruptive

The firm addressed concerns that Taiwan-based semiconductor company MediaTek could significantly steal Broadcom's share of Google's tensor processing unit (TPU) business, following a March report from The Information about MediaTek working with Alphabet to develop the next version of its custom chips

1

. Analyst Joseph Moore told investors that Morgan Stanley expects Broadcom to retain roughly 80% TPU share over time, calling bearish forecasts of 50% share or eventual displacement "premature"

2

. "Our view is that MediaTek participation is real, but not disruptive," the analysts wrote, comparing the situation to last year's Marvell/Alchip dynamic on Amazon's Trainium chip, where fears of full displacement proved overstated

Broadcom's Competitive Advantages in Custom ASICs

Morgan Stanley highlighted several factors that support Broadcom's position in custom ASICs and Google's TPU supply chain. The firm noted that high-bandwidth memory, packaging execution, and scale mean Broadcom's partnership with Google is likely to remain strong

1

. While acknowledging that Google is incentivized to reduce its reliance on any one chip provider to lower costs and gain "supplier optionality" as it produces multiple TPU generations, the relationship appears solid

1

. In April, Broadcom announced an expanded chip agreement with the search giant through 2013 to produce future iterations of its chips, and also announced plans to provide Anthropic with roughly 3.5 gigawatts of computing capacity through Google's chips

Execution Risks and Semiconductor Trends Favor Broadcom

Morgan Stanley flagged execution risk around MediaTek's packaging strategy, noting its Taiwan semiconductor team still expects MediaTek to rely on CoWoS capacity for 2nm TPU production, with EMIB packaging technology remaining unproven at the scale Google requires

2

. The firm also said potential cost savings could be difficult to realize, particularly around HBM memory, since Broadcom has already secured supply under existing contracts

2

. Morgan Stanley estimated Broadcom will generate roughly $120 billion in AI revenue in fiscal 2027, with TPU-related revenue around $80 billion, though it expects TPU's share of total AI revenue to decline to about 60% as newer ASIC customers ramp

Broadcom Expands AI Chip Partnerships Beyond Google

Broadcom has several other partnerships strengthening its position in the AI hardware ecosystem. In April, Meta extended its deal with Broadcom for its custom silicon

1

. Last week, Apple announced an extension of its Broadcom partnership in a $30 billion-plus chipmaking deal, which helped Broadcom shares rally nearly 5%

1

. Morgan Stanley maintained its buy-equivalent rating on Broadcom's stock with a $502 price target, stating: "We view Broadcom as one of the best growth stories in semis, supported by its leadership in custom ASICs, strong networking franchise, increasing AI revenue diversification, and a management team we trust to execute through product transitions"

2

. The firm concluded that while the MediaTek/TPU debate is a real overhang, the market is overstating the risk to Broadcom's growth trajectory
