Qualcomm Nears $4B Modular Acquisition as Tech Megacaps Shed $500B on AI Spending Anxiety

Qualcomm is in advanced talks to acquire AI chip startup Modular Inc. for approximately $4 billion, while U.S. tech megacaps lost over $500 billion in combined market value on Monday as investors questioned whether massive AI infrastructure spending will ever pay off.

The dual developments on June 22 capture the central tension in the AI industry right now: companies are pouring unprecedented sums into the build-out, but the market is increasingly demanding proof of returns.

Qualcomm Goes All-In on AI Silicon

Qualcomm is in advanced discussions to acquire Modular Inc., an AI chip startup, in a deal valued at roughly $4 billion, Bloomberg first reported Monday. An announcement could come "in the near future," according to people familiar with the matter.

Modular operates a platform that lets developers deploy AI models across different computer chips without rewriting code. The acquisition would give Qualcomm a hardware-agnostic software and compiler layer as it builds a fuller AI compute platform spanning connectivity, edge, and data center.

This is Qualcomm's second massive AI chip acquisition in weeks. The company is also in advanced talks to acquire Tenstorrent for $8 to $10 billion. Together, the two deals would commit over $14 billion to AI silicon, marking CEO Cristiano Amon's most aggressive pivot beyond the company's mobile-processor roots.

Qualcomm has already acquired Ventana Micro Systems, a RISC-V startup, and Alphawave Semi for connectivity IP. The company confirmed it pulled forward custom ASIC data-center chip shipments into calendar 2026. Bernstein analyst Rasgon called the Tenstorrent price tag "somewhat expensive for a startup asset" but noted it was still cheaper than Groq would have been.

Tech Megacaps Erase Over $500 Billion in Market Value

The broader market delivered a harsh verdict on AI spending Monday. Alphabet dropped 6% in its worst single-day decline since May 2025, erasing roughly $256 billion in market capitalization. Amazon fell 4.8%, while Meta and Microsoft each declined about 3%. Together, Amazon, Meta, and Microsoft shed over $248 billion in value.

SpaceX slid more than 10% for its third straight session after its June 12 IPO, and the company also announced a new notes offering on Monday. The cumulative sell-off across all megacap tech names exceeded $500 billion in a single trading day.

The immediate trigger for Alphabet's decline was the departure of John Jumper, the Google DeepMind senior research scientist who won the 2024 Nobel Prize in Chemistry for his work on AlphaFold. Jumper is leaving for Anthropic, a loss that signals the talent war between frontier AI labs is intensifying at the highest levels of research capability.

The Core Anxiety: $700 Billion in Spending, Unproven Returns

Behind the sell-off is a straightforward question: will the hyperscalers ever get their money back? Total projected AI infrastructure spending in 2026 is approximately $700 billion, nearly double 2025 levels. Google pays SpaceX $920 million per month for GPU capacity. Amazon guided $200 billion in capex for the year. Nvidia raised $25 billion in bonds with $85 billion in demand.

Yet clear evidence that AI products can generate returns justifying those spends remains elusive. "This is more of a broader sector pullback on ongoing anxiety over tech companies' massive capital spend on the AI infrastructure," said David Wagner, head of equity and portfolio manager at Aptus Capital Advisors.

The market is splitting sharply between winners and losers. Companies supplying the AI build-out, like memory maker Micron Technology, rose 5.8% to record highs after announcing a strategic agreement with Anthropic. "There's a distinguishing aspect of this market between those who are receiving the checks, like memory names, and those who are writing the checks," Wagner said.

White House Launches Quantum Offensive

In a separate but related development, President Trump signed two executive orders Monday aimed at accelerating U.S. quantum technology. One order directs the Pentagon and Department of Energy to build a powerful quantum computer for scientific research by 2028, while the other mandates migration of key government systems to post-quantum cryptography by 2030 or 2031.

The quantum push is explicitly framed as a response to Chinese competition and carries direct implications for AI. Quantum computers capable of breaking current encryption could fundamentally reshape cybersecurity, while quantum-enabled sensors could detect underground activity from space. The Commerce Department has already announced $2 billion in equity stakes across nine quantum-computing companies.

The orders arrive as Congress separately moved toward a bipartisan deal on children's online safety legislation that could serve as the outline for a broader AI framework before July 4. A bipartisan group of lawmakers also asked the Commerce Department for the legal rationale behind its export control directive issued to Anthropic, which legal analysts say was poorly drafted.

Shares of U.S. technology megacaps tumbled on Monday as SpaceX fell for the third straight session and hyperscalers dropped on growing concerns over massive AI-related capital spending.
