Don't miss

Marvell and Lumentum both fall despite a proposed $115 billion AI-infrastructure deal, exposing investor unease about the sector’s biggest bets.

The brief

Marvell’s proposed $115 billion all-stock acquisition of Lumentum would create a major AI-infrastructure company, but both stocks fall as investors reassess the scale and risks of such deals.

The deal’s reception reflects broader volatility in highly valued chip companies, where the promise of AI infrastructure now competes with concern over valuation and execution.

Marriott shares rise after stronger global hotel demand helps the company beat expectations and raise annual profit guidance, with revenue per available room central to the discussion.

Rivian rallies after strong results and a UBS upgrade, though questions around R2 SUV demand, its year-to-date decline, and high short interest keep the move unsettled.
