TL;DR

The iShares Expanded Tech-Software ETF (IGV) closed May 2026 up 21%, its best monthly gain since October 2001. Earnings blowouts from Dell Technologies and Snowflake dismantled the "SaaSpocalypse" thesis that AI would destroy enterprise software revenue. Instead, AI is generating new software spending faster than it is displacing existing subscriptions. The S&P 500 hit a record 7,580 and posted its ninth consecutive weekly gain.

What Happened

The enterprise software sector wrapped May 2026 with a historically significant rally. The iShares Expanded Tech-Software ETF (ticker: IGV), which holds leading enterprise software names, gained 21% for the month. That is the best monthly performance for the fund since October 2001, according to CNBC. From its April low, IGV climbed 35%, a recovery that compressed short interest across the sector.

The final acceleration came from two back-to-back earnings blowouts. On Thursday, Snowflake reported results that beat expectations and erased fears about AI-driven customer losses. The stock surged 36% in a single session, its best day on record, lifting ServiceNow, Workday, Oracle, and Palantir in tandem.

On Friday, Dell Technologies delivered what CNBC described as its best single-session gain since returning to public markets in 2018. Shares rose 32% after Dell reported Q1 revenue of $43.8 billion against a consensus estimate of $35.77 billion, and adjusted earnings per share of $4.86 against a $2.96 estimate. AI server revenue specifically grew 757% year over year. The company guided for roughly $60 billion in AI server sales for the full year.

Those catalysts carried broader indices to fresh records. The Nasdaq Composite closed at 26,972, while the S&P 500 settled at 7,580 for its ninth straight weekly gain. The streak ties the longest run for the index since late 2023. For the full month of May, the Dow Jones Industrial Average crossed 51,000 for the first time, closing out a strong month across all major benchmarks.

Why Markets Moved

The core driver is a narrative reversal. For most of the past 18 months, a significant portion of the investment community had been pricing in a structural decline for enterprise software. The concern, sometimes labeled "SaaSpocalypse" in market commentary, held that large language models and AI coding tools would allow companies to consolidate or cancel SaaS subscriptions, compressing the recurring revenue that justified elevated software multiples.

The May earnings cycle invalidated that thesis in concrete revenue terms. Snowflake's data cloud business accelerated because AI applications require massive structured data pipelines that run through Snowflake's platform, not around it. Dell's AI server demand came from hyperscaler and enterprise customers expanding infrastructure to train and run AI models. Both companies are benefiting from the same cycle: AI adoption creates new software spending categories rather than merely cannibalizing existing ones.

The market re-rated the sector accordingly. When a prevailing bear thesis collapses under hard earnings evidence, multiple expansion tends to be fast and concentrated, as May 2026 demonstrated.

Implications for Trader Cohorts

Stock traders: The shift from "AI kills SaaS" to "AI accelerates SaaS" is a re-rating event with unresolved company-level variation. Salesforce notably did not participate in May's rally, signaling that the market is waiting for AI-revenue proof points company by company. Traders assessing entry points will need to distinguish between names that have already repriced and laggards that still carry the old narrative as overhead resistance.

Futures traders: Nine consecutive weekly gains in the S&P 500 compress near-term volatility premium, but they also raise the cost of any sharp reversal. Breadth has been narrower than headline index performance implies. Technology is carrying a disproportionate share of the rally, so a single weak earnings report from a major platform could have outsized index impact in June.

Options traders: Software sector implied volatility compressed significantly this month as realized moves ran lower than expected on the downside but sharply higher on the upside. Near-term options in IGV and individual software names have cheapened, but the risk is still asymmetric around upcoming earnings catalysts like Salesforce.

Potential positives vs negatives

Positives: Dell's AI server backlog guidance extends demand visibility into Q3 and Q4, which could pull forward spending updates from HPE, Super Micro, and NetApp. Snowflake's result de-risked the broader data infrastructure segment. And the derating that suppressed software multiples for roughly 18 months has largely reversed, removing a structural headwind that had weighed on growth stock positioning.

Negatives: IGV's 35% recovery from its April trough means the rerating trade has already captured most of its initial upside. Salesforce earnings in early June are the next critical test; if the company fails to demonstrate clear AI-driven revenue contribution, doubt about the narrative's universality could return. The rally has also been concentrated in infrastructure-adjacent software, leaving pure-play CRM and HR tech names lagging, which raises questions about whether AI tailwinds are broad-based or specific to data and hardware adjacent platforms.

What Could Happen from Here

Base case (60%): The software rally consolidates in early June as the earnings-driven momentum fades into a quieter reporting period. IGV holds above key support from its April base, and traders wait for Salesforce earnings and broader macro data as the next catalyst. A Salesforce beat would confirm the theme across the full sector, while a miss creates a short-term rotation out of pure-play SaaS names. This scenario is confirmed by IGV trading in a defined range with below-average volume through the first two weeks of June.

Upside case (25%): Salesforce and other May laggards report AI-driven beats in coming weeks, extending the sector re-rating across all software categories. IGV breaks to all-time highs, and the software sector leads broader market performance through Q2. This would be confirmed by Salesforce guiding above consensus on AI-linked revenue lines and by further hyperscaler capex announcements that keep server demand high for Dell and its infrastructure peers.

Downside case (15%): The market begins pricing in a slower enterprise AI adoption cycle after the initial infrastructure wave peaks. If hyperscaler earnings updates in July reveal elevated server inventory without corresponding revenue conversion, Dell's forward guidance could face downward revision. This scenario would be confirmed by Dell or Snowflake issuing guidance cuts, or by a broader risk-off rotation triggered by macro data deterioration or a shift in Fed policy expectations.

What to Watch Next

  • Salesforce earnings: The clearest pending test of whether AI monetization extends beyond infrastructure names into pure-play enterprise software.
  • Fed speaker commentary next week: Software valuations are rate-sensitive; any shift in the market's rate-cut expectations could introduce multiple compression even alongside strong earnings momentum.
  • S&P 500 breadth indicators in early June: A post-streak consolidation is historically common; watch for deteriorating advance/decline data as an early signal of distribution.
  • Hyperscaler capex updates in July earnings: Microsoft, Google, and Amazon capital expenditure guidance directly drives the server and data infrastructure demand that is lifting Dell and Snowflake.
  • IGV ETF price action: Whether the fund holds above its April breakout level in June will be the clearest technical confirmation of whether May's rally marks a new leg or sets up a reversion trade.
