Datadog proposes $4 billion deal for Upwind, which the startup rejects

Datadog announced an offer of nearly $4 billion to acquire cloud‑cybersecurity startup Upwind. Upwind, valued at about $3.8 billion after a recent $300 million funding round, declined the proposal. The news sent Datadog shares down 5% to $259.31 and added pressure on the broader tech market.

The rejection leaves the acquisition uncertain, keeping the premium‑priced deal off the books and preserving Upwind’s independence. Datadog’s stock slide reflects investor concerns over a large, unconfirmed outlay and potential dilution.
