Analysis
Datadog has offered about $4 billion to acquire cloud security startup Upwind, The Information reported on October 22. The article is paywalled beyond the headline, and neither company has confirmed the terms or whether the offer has been accepted.
What's changed since Pulse previously covered Upwind's funding: that story tracked a $300 million raise at a $3.8 billion valuation.
“Investors in Upwind's last round will be watching whether a final price closer to its $3.8 billion mark, or something higher, actually materializes.”
A $4 billion acquisition offer would value Upwind only modestly above that private mark -- roughly a 5% premium -- rather than the steep strategic markup security acquirers have sometimes paid in a hot M&A market.
Datadog has used acquisitions before to fill gaps in its observability and security product lines, and a deal of this size would rank among its largest to date. The cloud security category has consolidated quickly in 2026: Google closed its roughly $32 billion acquisition of Wiz earlier in the year, and Palo Alto Networks has continued rolling up smaller security vendors. An Upwind deal would put Datadog more directly in that competitive set, adding cloud workload and runtime security coverage to its platform.
Because the deal is reported, not confirmed, the terms -- price, structure, and whether Upwind's board has accepted -- could still change or fall apart entirely before any signing is announced. Investors in Upwind's last round will be watching whether a final price closer to its $3.8 billion mark, or something higher, actually materializes.
