California Deal-Room Trends 2026: SF Leads, Irvine Falls
Read summarized version with
Deal-room activity grew strongly across several major California business centers during the analyzed 2026 period, although growth was not evenly distributed between cities.
San Diego recorded the fastest growth at approximately 220%, followed by San Francisco at 184%. Los Angeles increased by 82%, while Palo Alto recorded more moderate growth of 47%.
Other California cities moved in the opposite direction. Irvine recorded a decline of approximately 42%, while Anaheim’s activity remained broadly stable, decreasing by approximately 1.37%.
San Francisco dominates activity while San Diego grows fastest
San Diego recorded the fastest percentage increase among the California cities included in the analysis, with deal-room activity growing by approximately 220%.
The increase was significant, although it occurred from a relatively small starting base.
San Francisco remained the substantially larger deal-room market while recording growth of approximately 184%. The city accounted for the majority of observed California activity during the latest period.
San Francisco’s position is consistent with its concentration of venture-capital firms, software companies, financial advisers and technology businesses. These organizations frequently use secure document environments during fundraising, investment reviews, acquisitions, strategic partnerships and financial due diligence.
San Diego has a different but complementary corporate base, including biotechnology, healthcare, technology and research-focused companies. These industries may require secure systems for sharing intellectual property records, clinical information, financial statements and transaction documents.
A 2026 review of California’s corporate M&A environment published by Chambers and Partners identifies San Francisco, San Diego and Los Angeles as important centers for technology, life sciences and corporate transaction activity.
Los Angeles and Palo Alto also record growth
Los Angeles deal-room activity increased by approximately 82.47%.
Companies in Los Angeles may use virtual data rooms for transactions involving entertainment, media, technology, real estate and professional services. These processes can require controlled access to contracts, intellectual property, financial records and ownership information.
Palo Alto recorded a smaller increase of approximately 47.95%. Although its overall volume remained limited within the dataset, the city’s position within Silicon Valley makes it relevant to venture capital, software investment and technology-focused transactions.
The geographic concentration of growth around San Francisco, Palo Alto and Los Angeles coincides with continued investor interest in technology and digital infrastructure.
PwC’s 2026 technology, media and telecommunications outlook found that global TMT deal value increased by 48% during the first five months of 2026, with technology accounting for 89% of total deal value across the sector.
Technology activity was particularly concentrated around AI, software, data infrastructure, cybersecurity and platforms that help companies adopt AI at scale.
These broader trends do not directly explain the city-level changes within the Orangedox dataset, but they provide useful context for increased secure document activity across California’s major technology centers.
Irvine moves in the opposite direction
Irvine recorded the largest decline among the California cities included in the analysis, with activity decreasing by approximately 42.47%.
Anaheim recorded a much smaller decline of approximately 1.37%, indicating that activity remained broadly stable.
The decrease in Irvine contrasts with the strong growth recorded in San Francisco, San Diego and Los Angeles. The findings suggest that California’s increase in deal-room activity was concentrated in particular corporate centers rather than distributed evenly across the state.
The available data does not identify why activity declined in Irvine. The decrease could reflect transaction timing, changes in customer composition or reduced deal-room usage among the organizations observed during the period.
California reflects a concentrated deal environment
The city-level findings broadly align with a US transaction market characterized by larger deals and concentrated activity.
PwC reported that US M&A deal value reached $1.2 trillion during the first five months of 2026, nearly double the $603 billion recorded during the corresponding period in 2025. However, deal volume declined by 4%, with much of the increase in value coming from larger transactions.
Technology has been one of the strongest areas of the market. EY found that technology M&A deal value doubled and deal volume increased by 29% from April through June 2026 compared with the same period in 2025.
This type of transaction environment can produce uneven geographic growth. Cities with large concentrations of technology companies, venture-capital investors, advisers and transaction professionals may generate more secure document activity than markets with fewer active transactions.
The Orangedox findings show a similar pattern, with San Francisco retaining a dominant position by volume while San Diego recorded the fastest percentage growth.
Secure workflows support transaction preparation
Companies preparing for an acquisition, investment or fundraising round may need to share financial statements, contracts, capitalization records, intellectual property documents and other confidential information.
Virtual data rooms allow these documents to be stored within a controlled environment where access can be restricted, monitored or revoked.
Their use may begin before a transaction is formally announced and continue through due diligence, negotiation and closing. A company may also maintain a data room between transactions to keep important corporate information organized and ready for review.
The growth recorded in San Francisco, San Diego, Los Angeles and Palo Alto therefore indicates increased secure document preparation and corporate collaboration across several of California’s leading business centers.
Methodology
The analysis is based on anonymized corporate activity observed through the Orangedox platform during the analyzed periods in 2025 and 2026.
The comparison uses a projected 2026 baseline calculated from 2025 activity. Growth rates were normalized to remove the influence of changes in marketing activity and provide a clearer indication of underlying demand.
The figures measure observed corporate users rather than unique M&A transactions. Some activity may relate to fundraising, audits, portfolio reporting, corporate document sharing or other workflows.
Percentage increases for cities with smaller initial samples may appear disproportionately high. The findings describe activity within the analyzed Orangedox dataset.
