AI Stocks and Crypto Crash After Democratic Win
US stock markets reversed sharply after the Democratic midterm victory stoked fears of AI regulation, with the Nasdaq falling 5% into correction territory. Chip stocks AMD, Micron, and Marvell each dropped double digits, while Tesla slid over 10%. Bitcoin slipped below $76,000, and gold hit a record high above $4,120 as investors rotated into defensive sectors. Data Center Watch found that 78% of elected lawmakers and 94% of governors support regulating data centers, with Texas and Georgia electing pro-regulation governors, potentially hiking AI infrastructure costs. Despite the sell-off, some analysts view it as profit-taking, citing falling oil prices, lower Treasury yields, and strong earnings. Upcoming economic data will likely shape market direction, though disappointing earnings from Alphabet and Amazon added to negative free cash flow concerns.
Marvell downgraded on $100B Lumentum acquisition concerns
Bank of America downgraded Marvell Technology to neutral from buy, citing concerns over its announced all-stock acquisition of photonics firm Lumentum Holdings. The deal, valued at over $100 billion, aims to position Marvell as a leader in AI connectivity but faces extended regulatory review, limited EPS accretion, and potential customer conflicts. Analyst Vivek Arya lowered the price target to $225 from $400, implying 31% upside. Shares closed down 13% on Monday, adding to a 12% decline over three months. The downgrade contrasts with consensus, as most of the 45 analysts covering the stock maintain buy ratings.
Marvell to Acquire Lumentum in $115B All-Stock Deal
Marvell Technology has agreed to acquire photonics specialist Lumentum in an all-stock transaction valued at $115 billion including debt, with an equity value of approximately $102.5 billion. This marks one of the largest tech deals, surpassing Microsoft's acquisition of Activision Blizzard and Dell's purchase of EMC. Lumentum shareholders will receive 4.5 Marvell shares per share, representing a 23.9% premium. The combined company aims to lead in AI connectivity, capitalizing on the shift from copper to optical interconnects in AI data centers, with co-packaged optics projected to expand the addressable market to $550 billion. Marvell expects over $1 billion in annual cost synergies and positive EPS contribution in the first year after closing. Both boards approved unanimously, with Marvell CEO Matt Murphy retaining his role and Lumentum CEO Michael Hurlston joining the board. The deal, expected to close in the first half of 2028, faces shareholder and antitrust approvals. Market reaction was skeptical, with shares of both companies falling. Nvidia, which invested $2 billion in each company in March 2026, shares circular dealmaking concerns. This follows Marvell's earlier acquisition of Celestial AI.
