Twenty announced M&A deals worth roughly $600 billion are still waiting to close as of August 2026. The largest pending acquisition is Paramount Skydance's $110billion takeover of Warner Bros. Discovery at $31.00 per share. The Justice Department cleared it in June 2026, but twelve state attorneys general sued to block it and trial is set for March 2, 2027. Union Pacific's merger with Norfolk Southern ranks second at $85 billion and has been held in abeyance by the Surface Transportation Board since May 2026. Charter and Cox, Boston Scientific and Penumbra, and Santander and Webster Financial are all awaiting final regulatory sign-off. This tracker lists every pending deal by value with its price basis, expected close date and the specific regulatory approval still outstanding.
Deal volume will likely skew to fewer deals with larger price tags. Strategic buyers will focus on scale in areas that are difficult to organically grow, and sponsors will focus on quality in areas where public market pricing still offers room for value creation. Buyers will focus on targets that provide clear growth opportunities through the products they offer or control of critical infrastructure such as data centers and security.

Regulatory risk: how likely is each pending deal to actually close?
Not every announced megadeal closes. Below is DealRoom's risk read on each of the 20 pending deals as of Q2 2026 — assessed against the active regulatory dockets and public statements from the FTC, DOJ, FCC, CFIUS, and equivalent foreign authorities. Refreshed quarterly.
Withdrawn and Blocked M&A Deals: Recent Cautionary Tales
Not every announced megadeal closes. Tracking withdrawn or blocked deals matters because the regulatory framework that killed them is the same framework that will be applied to today's pending mega-mergers - and the patterns repeat. Here are the most consequential failed announcements of the past three years, with the killer in each case.
Adobe / Figma - $20B (withdrawn December 2023)
Adobe abandoned its $20B Figma acquisition after 15 months of antitrust review by the UK CMA, EU Commission, and US DOJ all signaled they would block. Adobe paid Figma a $1B termination fee. Pattern to watch: any deal that combines a category leader with the strongest emerging challenger draws coordinated multi-jurisdiction review.
Spirit Airlines / JetBlue - $3.8B (blocked January 2024)
A federal judge blocked JetBlue's acquisition of Spirit on antitrust grounds, citing harm to ultra-low-cost-carrier competition and consumer pricing. Spirit subsequently filed for bankruptcy in November 2024. Pattern to watch: US DOJ now treats elimination of a pricing disruptor as standalone consumer harm - directly relevant to today's Allegiant / Sun Country pending deal.
Microsoft / Activision Blizzard - $69B (closed October 2023, but only after extended fight)
Closed eventually but only after the FTC sued, the UK CMA initially blocked, and Microsoft was forced to divest cloud-streaming rights to Ubisoft. Pattern to watch: mega-deals can survive opposition with structural concessions, but expect 18+ months and substantial divestitures - directly relevant to Netflix / WBD's pending review.
Tapestry / Capri (Coach + Michael Kors) - $8.5B (blocked, then abandoned 2024)
Federal court blocked the deal on antitrust grounds in October 2024; Tapestry abandoned the transaction the next month. Pattern to watch: luxury and fashion consolidation now subject to fresh competition-law scrutiny that didn't apply pre-2023.
Kroger / Albertsons - $24.6B (blocked September 2024)
Multiple federal and state courts blocked the supermarket merger; deal officially terminated December 2024. Pattern to watch: divestiture-as-fix proposals that rely on a smaller buyer (in this case C&S Wholesale) are now treated skeptically by courts as inadequate competitive remedies.

5 M&A Deals to Watch in 2026
Out of the 20 announced deals in our 2026-2027 tracker, five carry outsized strategic significance - either because of the size of the prize, the precedent the regulatory review will set, or the second-order effects on adjacent industries.
- Netflix / Warner Bros. Discovery - $83 billion. The single largest transaction on the 2026 board. If it closes, it creates the world's only true scale streaming-plus-Hollywood-library platform. If it's blocked or restructured, it locks in the current fragmented streaming landscape for another decade. The DOJ + EU review here will set the antitrust template for every follow-on streaming consolidation through 2030.
- PIF, Silver Lake, Affinity / Electronic Arts - $55 billion. The largest video-game acquisition in history, and the largest US tech acquisition by a Saudi-led consortium. The CFIUS review will signal how the US government treats sovereign-wealth-led acquisitions of major American IP-heavy companies - a precedent that affects pending deals across pharma, semiconductors, and consumer tech.
- Charter Communications / Cox Communications - $34.5 billion. Combines the #2 and #3 cable operators in the US. The FCC review will determine whether further cable consolidation is permissible at all - and the divestiture demands attached to any approval will reshape regional broadband competition for the next decade.
- Apollo + Stone Point / Western Alliance - $11 billion. The first major regional-bank acquisition since the 2023 stress. How the Federal Reserve approaches review here - speed, conditions, capital requirements - will dictate whether the broader regional-bank consolidation thesis materializes in 2026-2027 or stalls again.
- Boston Scientific / Penumbra - $14.5 billion. Tests whether mid-cap med-tech consolidation can clear FTC review without major divestiture. A clean approval here unlocks at least 5-7 follow-on med-tech deals on the back-burner; a contested review or block freezes that pipeline.
The rest of the 20-deal pipeline below is meaningful but more contained - pharma bolt-ons, software take-privates, and post-close synergy realizations rather than precedent-setting transactions.
Upcoming Healthcare and Pharma M&A Deals (2026-2027)
Fourhealthcare and pharma acquisitions are pending as of August 2026, worth $48.5billion combined. Boston Scientific is buying Penumbra for $14.5 billion, SunPharma is buying Organon for $11.75 billion, Merck KGaA is buying Bio-Technefor $11.3 billion and AbbVie is buying Apogee Therapeutics for $10.9 billion.Patent-cliff pressure is the common driver: each acquirer is buying commercialor late-clinical assets to offset revenue coming off exclusivity before 2030.
- Boston Scientific / Penumbra - $14.5B. Stroke and peripheral interventional platform. FTC review underway; expected close Q4 2026.
- Sanofi / Dynavax Technologies - $2.2B. Vaccines portfolio addition. Standard biotech bolt-on; expected close Q3 2026.
- GSK / RAPT Therapeutics - $1.9B. Clinical-stage immunology assets. Standard HSR; expected close Q3 2026.
- Eli Lilly / Ventyx Biosciences - $1.2B. Immunology pipeline. Standard HSR; expected close Q3 2026.
Upcoming Technology M&A Deals (2026-2027)
Five technology deals are pending in 2026-2027, totaling approximately $97.4 billion. The pipeline splits between AI-infrastructure plays (Anthropic stake, Cisco-Splunk synergy realization), enterprise-software take-privates (Hg Capital / OneStream, SoftBank / DigitalBridge), and the largest gaming acquisition in history (PIF / EA).
- PIF, Silver Lake, Affinity / Electronic Arts - $55B. Largest video-game acquisition ever. CFIUS + antitrust review; expected close Q1-Q2 2027.
- Cisco / Splunk (synergy realization) - $28B. Already closed; entry tracks integration milestones.
- Hg Capital / OneStream - $6.4B. PE buyout of enterprise CPM software. Standard HSR; expected close Q3 2026.
- SoftBank / DigitalBridge - $4B. Foreign acquirer in US data-center infrastructure. CFIUS review; expected close Q4 2026.
- Anthropic stake (rumored Google extension) - $4B. Status remains rumored. If formalized, expect heavy DOJ AI-concentration scrutiny.
Upcoming Energy M&A Deals (2026-2027)
Two pure-energy deals are pending in the 2026-2027 window, totaling approximately $1.2 billion of disclosed announced value. The energy supermajor consolidation wave (Devon-Coterra, Chevron-Hess, ConocoPhillips-Marathon) has slowed in early 2026 as the largest viable targets have been picked off.
- EGH / Hecate Energy - $1.2B. SPAC combination with a clean-energy developer. Standard regulatory path; expected close Q3 2026.
- Alphabet / Intersect Power - $4.75B (already closed Q1 2026). Vertical integration of clean-power generation under hyperscaler ownership; signals further hyperscaler-into-utility consolidation in 2026-2027.

Key Takeaways
- M&A deals picked up pace in 2025, gearing up steam into 2026, with a trend of fewer, larger deals being driven by AI, infrastructure, and strategic scale, rather than incremental growth.
- Buyers and investors are moving quickly, even in the face of continued headwinds of regulation, rates, and geopolitics, with a focus on high-quality assets where consolidation, technology, and valuation create outsized opportunities.
Deal-making has increased in all sectors and regions in 2025. Moreover, Europe has also seen active M&A deals, such as the acquisition of Vodafone Italia by Swisscom, which shows that consolidation is still an option despite intense regulatory pressures.
Nevertheless, the headwinds of rates, regulations, and geopolitics continue to impact M&A. Buyers and sellers are adjusting to these changes while executing the M&A process. This shows that the M&A pipeline is gearing up for a strong 2026.
