4 stocks to watch on Monday: PYPL, BA, SKHY, and SPCX

Stock index futures came under immediate pressure on Monday after President Donald Trump rejected an Iranian proposal for a seven-day ceasefire.

SpaceX (SPCX) was up 0.34% in premarket trade as Evercore said the Elon Musk-led company could see “significant” EBITDA upside as its Colossus data center business ramps. Analysts said Musk’s post on X indicated 780,000 GPUs are online across Colossus 1 and 2, with at least two and potentially three 220,000-GPU GB300 tranches expected by year-end. Evercore estimates that could lift capacity to about 2.3 GW with two tranches or 2.7 GW with three, above its 2.1 GW consensus estimate, implying higher 2H26 capex but potentially putting 2027 revenue and EBITDA significantly ahead of Street estimates.

PayPal (PYPL) rose 1.2% in early action amid renewed takeover speculation after talks between the Stripe/Advent consortium and the fintech firm reportedly ended. Traders cited a Betaville “uncooked” alert suggesting a U.S. technology company may be evaluating an all-stock takeover, while PayPal’s board is said to prefer an all-cash deal. The report also said Stripe and PayPal had hit an issue over a potential $2 billion break fee, with the consortium previously considering as much as $68 a share in cash.

SK Hynix (SKHY) shares fell 5% in premarket trade, their biggest decline in two weeks, after Bloomberg reported that its U.S. subsidiary Solidigm is considering a U.S. IPO as soon as next year that could value the data-storage maker at as much as $100 billion. The potential listing has raised concerns about the chipmaker’s ownership structure, while SK Hynix’s biggest holder, SK Square, tumbled more than 8%, and SK Inc., which controls SK Square, retreated more than 6%.

Boeing (BA) fell 2.56% in early action after discovering a software glitch in its 737 MAX series that could cause an automated navigation system to fail during certain landings. The issue can arise when pilots change flight paths following a missed approach, potentially requiring crews to fly manually as some autopilot features would be disabled. Airlines operating the 737 MAX were notified in August, and Boeing said the issue did not warrant safety concerns, according to a document obtained by The Wall Street Journal.
