Stocks making the biggest moves premarket: Moderna, Airbnb, Cloudflare, Affirm & more

Premarket moves were sharply mixed: Moderna raised its 2026 revenue-growth outlook to 15%-25% and rallied nearly 10%, while Cloudflare gained 19% on above-consensus quarterly guidance and JFrog rose 23% after raising full-year guidance. DraftKings fell more than 20% after a wider-than-expected 94-cent-per-share loss and revenue below estimates; Atlassian dropped more than 18% on weaker data-center revenue growth expectations, and Five9 fell more than 17% after cutting full-year adjusted EPS guidance. Lam Research surged nearly 11% after authorizing a $25 billion buyback, while other stocks moved on earnings, outlooks, deal news and AI-related sentiment.

Analysis

The useful signal is dispersion, not a broad risk-on read-through. The AI bounce does not resolve the key split: component demand can remain healthy while data-center operators struggle to convert contracted capacity into timely revenue. IREN’s delayed revenue ramp is a credibility and duration issue; treat the projected backlog as lower quality until delivery dates and customer acceptance are verified. That is a different risk from semiconductor suppliers, whose demand may be supported even if individual cloud projects slip. LRCX’s buyback can cushion its stock, but it is not evidence of stronger wafer-fab equipment demand.

Within software, NET and FROG have near-term guidance support, while TEAM’s disclosed data-center revenue trajectory raises a watch item around hosting mix and migration economics—not necessarily a deterioration in total customer demand. FIVN’s guidance cut alongside a cash acquisition adds integration and capital-allocation risk. The divergence argues against buying software indiscriminately.

Consumer results are also company-specific: ABNB’s beat supports travel resilience, but does not establish broad discretionary strength. DKNG’s miss exposes earnings sensitivity to sportsbook outcomes and revenue conversion; LYFT’s revenue shortfall despite bookings guidance near expectations points to monetization as a metric to monitor. MRNA’s raised outlook is a positive catalyst, but the durability of demand beyond the guided period remains unproven. Near term, earnings-driven gaps may dominate; over 1–3 months, revisions and delivery timing matter; over 6–18 months, AI infrastructure utilization and software hosting economics are the larger tests. Falsifiers include IREN confirming prompt delivery, TEAM stabilizing data-center revenue, or further downward guidance revisions among AI suppliers.

Key Decisions for Investors

• Prefer a small relative long NET / short TEAM position over a broad software bet, with entry after opening volatility settles. Reassess if TEAM clarifies that data-center declines are a temporary mix transition and total growth stabilizes, or if NET fails to convert guidance into subsequent revenue and margin delivery.
• Do not chase the AI-infrastructure rebound indiscriminately. Keep exposure tilted toward diversified semiconductor supply-chain names rather than IREN until IREN verifies the timing, customer acceptance, and economics of delayed revenue. A confirmed delivery schedule could invalidate the relative caution; another delay would strengthen it.
• Treat LRCX’s buyback as a technical support, not a demand thesis. Avoid adding solely on the authorization; monitor equipment orders and company outlook for confirmation. Weakening order indicators would outweigh the buyback cushion.
• Keep DKNG on a short/underweight watchlist rather than initiating into a potentially volatile post-earnings gap. Require evidence that revenue and loss trends are stabilizing before covering; improved sportsbook revenue conversion would falsify the cautious view.
