What Was Posted on X
Rough week for software. 81% of names down. ServiceNow off 34%. Multiple compression happens much more swiftly & brutally than multiple expansion.
Venture capitalist Tomasz Tunguz of Theory Ventures wrote that it was a rough week for software, that 81% of names were down and ServiceNow was off 34%, and that multiple compression happens much more swiftly and brutally than multiple expansion. The 81% count is his.
What ServiceNow Reported
ServiceNow’s release says third-quarter subscription revenues were $3,988 million, “representing 21% year-over-year growth”, and that current remaining performance obligations (cRPO), contract revenue due within 12 months, were “$13.65 billion, representing 20.5% year-over-year growth”.
Its guidance table gives fourth-quarter cRPO growth of 18.5%. On 28 October we reported that the company also raised its 2026 AI annual contract value target to $1.7 billion, and that chief financial officer Gina Mastantuono said on the call that strong early renewals “contributed about half of the beat in Q3”, in ServiceNow’s AI target piece.
How a Venture Investor Read the Week
Tomasz Tunguz, a venture capitalist at Theory Ventures, wrote on X on 31 October: “Rough week for software. 81% of names down. ServiceNow off 34%. Multiple compression happens much more swiftly & brutally than multiple expansion.” His post does not say which list of software companies the 81% counts.
This week we also covered the Fiverr chief executive’s earnings-call remarks on AI agents, in the Fiverr piece, and Factory’s own benchmark claims for its Droid agent against Claude Code, in the Factory Droid piece. Friday’s slide in chip stocks is in the Apple and Nvidia close.
The Structural Read
As we read the closes, ServiceNow’s one-day fall of 26.9% on 29 October was larger than the whole-week fall of any other stock in this piece, by our arithmetic.
As we read the release, the reported quarter grew: subscription revenues of $3,988 million, up 21%, and cRPO of $13.65 billion, up 20.5%. The guidance table gives fourth-quarter cRPO growth of 18.5%.
As we read the rest of the list, the moves were smaller and uneven: Salesforce fell 7.8%, Snowflake 5.9%, Workday 5.8%, Adobe 5.2% and Intuit 0.7%, against 2.0% for the Nasdaq, by our arithmetic.

Three Implications
FOR SERVICENOW Its release guides fourth-quarter cRPO growth to 18.5%, after 20.5% in the third quarter.
FOR SOFTWARE STOCKS By our arithmetic from Yahoo Finance closes, the software ETF IGV fell 5.7% in the week to 30 October, against 2.0% for the Nasdaq Composite.
FOR THE COUNT Tunguz wrote that 81% of software names fell during the week; his post does not say which list he counts.
The framework lists the stack this way: “The nine layers, top to bottom: Governance ยท Distribution ยท Agentic Harness ยท Foundation Models ยท Compute Capacity ยท Networking & Protocols ยท Silicon ยท Foundries & Packaging ยท Energy & Physical.”
As we read it, this week’s software moves sit at the layers where agents are built and sold to companies. The framework does not discuss this trading week.
What Is Not Established
CNBC’s article was not read; only its headline is quoted. The closing prices are Yahoo Finance’s, and the weekly moves are our arithmetic from Friday 23 October to Friday 30 October. The 81% figure is Tunguz’s, and his universe of names is not stated. The closes do not show why any stock moved.
This Week In The AI Supercycle
Execution Fault Lines, Concentrated Demand, and Geopolitical Firewalls
This week’s issue: the AI build is not short of demand for its parts. It is short of cheap money, and its end revenue rests on a narrow base of large, often venture-funded buyers.
ServiceNow closed the week to 30 October down 33.9% and the software ETF IGV down 5.7%, by our arithmetic from Yahoo Finance closes, so ServiceNow fell about 5.9 times as much. Its one-day fall on 29 October was 26.9%. Separately, its release guides fourth-quarter cRPO growth to 18.5%, after 20.5% in the third quarter.
A note on sourcing. Closing prices are Yahoo Finance’s; weekly and daily changes and the 5.9x ratio are our arithmetic. ServiceNow’s figures and guidance are from its Q3 2026 release. CNBC is cited by headline only. Tunguz’s 81% figure is his own.
