As 2026 enters its final quarter, we look back at the largest technology M&A deals announced in 2025 and the buyer priorities behind them, with the benefit of seeing which themes have carried into 2026. For founders, that retrospective offers a clearer view of where strategic and financial buyers have continued to deploy capital and what that may imply for positioning, timing and buyer selection.
The defining transaction was Google's $32 billion agreement to acquire Wiz, the largest pure-software acquisition ever announced. It was also one of the clearest examples of where strategic buyers were prepared to deploy significant capital: cybersecurity, AI capabilities and scaled software platforms with strong strategic relevance.
Those themes appeared repeatedly across the year. Security remained a priority for strategic buyers, AI increasingly became a build-versus-buy decision, and private equity continued to pursue scaled recurring-revenue software businesses. Among the largest transactions were Google’s acquisition of Wiz, Palo Alto Networks’ $25 billion agreement to acquire CyberArk and the $55 billion take-private of Electronic Arts.
This article ranks the biggest technology M&A deals announced in 2025 and examines what they can tell founders and investors about valuation, buyer appetite and transaction strategy. Deals are classified by announcement date, consistent with the L40° Tech M&A Deal Radar, with closing dates noted separately where relevant.
Looking back from 2026 provides a more complete view of the year: not simply which transactions generated the largest headlines, but where strategic and financial buyers ultimately chose to concentrate capital.
The ranking: biggest technology M&A deals of 2025
The table below ranks the largest technology deals announced in 2025 by disclosed value. Each row carries a one-line strategic read tied to one of the year's three buyer theses. The set is selective and sourced to primary releases, not padded to a round number.
Security was the year's clearest thesis
Cybersecurity accounted for two of the largest technology acquisitions announced in 2025. Google's $32 billion all-cash acquisition of Wiz was the clearest example: a strategic buyer committing a record amount to cloud security as infrastructure at the center of its broader cloud and AI strategy.
The valuation was exceptional. Wiz had crossed $1 billion in ARR in 2025, implying a transaction value of roughly 30x reported ARR. That is a strategic outlier, not a market benchmark, but it illustrates the premium a buyer may support when an asset is considered important to a broader platform strategy.
Palo Alto Networks' $25 billion agreement to acquire CyberArk reinforced the same theme from a different angle. The acquisition would establish identity security as a core pillar of Palo Alto Networks' platform, extending its offering across human, machine and AI identities. Two transactions of this scale in the same category underscored how strategically important cybersecurity had become to large technology buyers.
- In retrospect: The prominence of cybersecurity in 2025 is worth putting in context against the market that followed. In 2026, security remains one of the most consistent acquisition themes tracked in the L40° Tech M&A Deal Radar, particularly across identity, AI security, exposure management and fraud prevention. But buyer activity has broadened materially: AI infrastructure and applications, fintech, vertical software, data and analytics, and healthtech are also attracting significant capital, and several of the year's largest transactions sit outside cybersecurity. The 2025 concentration in Wiz and CyberArk therefore looks less like a one-category market and more like an early expression of a broader willingness by strategic buyers to pay for technology they view as critical infrastructure.
- Founder takeaway: The interest in cybersecurity does not come from category exposure alone. It comes when a company combines strong recurring revenue and enterprise adoption with a capability that is difficult to replicate and strategically important to a specific buyer. For founders, that makes buyer fit and strategic relevance as important as the underlying market multiple. See how buyers frame SaaS multiples and valuation benchmarks against that standard.
AI moved from feature to acquisition rationale
Several of 2025's largest technology deals reflected a broader build-versus-buy decision around AI. Rather than treating AI as an incremental product feature, strategic buyers acquired established platforms, technology and teams that could accelerate their position in areas becoming central to their product roadmaps.
ServiceNow's $2.85 billion acquisition of Moveworks, its largest acquisition at the time, added an AI assistant and enterprise search platform to its agentic AI strategy. Capgemini's $3.3 billion acquisition of WNS similarly centered on the shift toward agentic AI-powered business operations.
- In retrospect: That pattern has continued into 2026. Transactions tracked in the L40° Tech M&A Deal Radar show buyers acquiring AI capabilities across the stack, from model routing and observability to agent platforms, developer tools and data infrastructure. The thesis has therefore moved beyond acquiring AI talent or standalone applications: buyers are increasingly using M&A to secure the infrastructure and capabilities required to put AI into production.
- Founder takeaway: Buyers are not paying simply for an AI label. The strongest acquisition cases combine proprietary technology with a product already deployed in real workflows, commercial traction and a capability that would be difficult or time-consuming for the acquirer to replicate internally.

Sponsors returned to scaled software
Financial sponsors re-entered software at scale in 2025, and their logic differs from strategic logic in ways that matter to a seller. Thoma Bravo's $12.3 billion agreement to acquire Dayforce was one of the clearest examples, taking a scaled human capital management software platform private at a 32% premium to its unaffected share price.
At the top of the market, the $55 billion take-private of Electronic Arts by a consortium of the Public Investment Fund, Silver Lake and Affinity Partners became the largest sponsor-led take-private on record. It is a games publisher rather than pure software, so it belongs in the ranking as the year's largest technology-sector deal, distinct from Wiz as the largest pure-software transaction.
Sponsor underwriting is not built around immediate integration. It is built around a multi-year value-creation plan, supported by durable revenue, cash-flow generation, operating levers and a defined investment horizon. That creates a different diligence process and a different set of questions from those of a strategic acquirer.
- In retrospect: The sponsor market has become more selective in 2026. Private equity remains active in technology, but uncertainty around AI disruption and financing has raised the underwriting bar for traditional software platforms. Large platform buyouts have slowed, while sponsors have placed greater emphasis on add-ons, growth investments and businesses with clearer cash-flow durability, vertical specialization or defensible data and workflow positions. The 2025 return of large software take-privates therefore marked a reopening of the market, not a return to indiscriminate software buying.
- Strategic versus sponsor logic: A strategic buyer underwrites fit, integration and capabilities it would otherwise need to build or acquire elsewhere. A sponsor underwrites cash-flow durability, downside protection and a credible path to value creation over the hold period. For founders, the distinction affects not only valuation, but also deal structure, diligence priorities and which buyers belong in the process, which is why buyer-universe design is a core part of sell-side advisory.
What 2025's deals mean for technology founders
The headline transaction values are not direct comparables for a mid-market company. A $5M to $100M ARR business is not priced off a $32 billion acquisition. What the largest deals of 2025 do reveal is where buyer conviction was strongest: which categories were treated as strategically important, which capabilities buyers were willing to acquire rather than build, and where financial sponsors were prepared to underwrite scaled software assets.
For founders considering whether and when to run a process, those are the important nuances in the market. Cybersecurity, proven AI capabilities and durable recurring-revenue businesses attracted significant buyer interest in 2025, and those themes remain visible in 2026, even as activity has broadened across vertical software, fintech, data and analytics, healthtech and AI infrastructure. For those building in these verticals, the opportunity is not simply to operate in one of those categories, but to demonstrate why the company is strategically relevant to a specific set of buyers. That’s also a logic that can also be expanded beyond these verticals.
That said, value is rarely captured passively. The outcome of a sell-side process also depends on positioning the business around the factors buyers care about, identifying the right buyer universe and testing appetite through a competitive process.
For the current-year continuation of this analysis, the L40° Tech M&A Deal Radar tracks how these themes are developing across 2026.
How this ranking is built
Deals are ranked by disclosed transaction value and included by announcement date in 2025, consistent with the L40° Tech M&A Deal Radar. Close dates are noted where they differ from announcement, and several 2025 closings that were announced in 2024 are treated as out of scope for the ranking. Figures are sourced to company releases, regulatory filings, and neutral reporting, with the source carried on the relevant figure. The list is selective, not exhaustive, and values reflect the parties' own disclosures.
What 2025 still tells founders in 2026
The most useful signal from 2025 is not the size of the transactions, but where buyer conviction concentrated. Strategic acquirers deployed capital behind cybersecurity, AI capabilities and critical software infrastructure, while financial sponsors returned selectively to scaled, durable software assets. Many of those themes remain active in 2026, even as M&A activity has broadened across vertical software, fintech, data and analytics, healthtech and AI infrastructure.
Valuation is therefore shaped not only by the quality of the business, but by how many credible buyers have a strategic or financial reason to compete for it. The strongest outcomes come from identifying those buyers early, positioning the company around the value drivers they underwrite, and creating competitive tension through a structured process.
