For over 150 years, MetLife has stood as a colossus in the global insurance landscape. Once famously associated with Snoopy and the Peanuts gang, the company has, in the last decade, executed a radical brand transformation. It has pivoted away from the volatile “retail life” market (selling individual policies to families at kitchen tables) to become a B2B juggernaut, positioning itself as the “workforce ally” for thousands of corporations worldwide. Today, MetLife’s primary battleground is not the living room, but the Human Resources office. It competes to be the engine behind employee benefits packages—dental, vision, disability, and life insurance—that Fortune 500 companies use to recruit and retain talent.
However, this strategic pivot has placed MetLife in a crowded and fiercely contested arena. The “financial wellness” sector is no longer just about paying out death claims; it is about holistic employee health, wealth management, and retirement security. In 2026, MetLife finds itself besieged on multiple fronts. In the United States, it fights a trench war with legacy giants like Prudential and New York Life for control of the group benefits market. In Japan—MetLife’s second-largest and most critical market—it faces a unique “frenemy” in Aflac, which dominates the cancer insurance niche. Meanwhile, agile specialists like Unum and Principal Financial Group are using superior technology to chip away at MetLife’s dominance in the disability and SMB (Small and Midsize Business) sectors.
The stakes are incredibly high. As interest rates stabilize and the global workforce demands more personalized benefits, the winner will not be the company with the biggest balance sheet, but the one that can best integrate into the digital lives of employees. MetLife’s “Next Gen” strategy focuses on efficiency and customer centricity, but its rivals are executing their own aggressive playbooks. From the mutual structures of MassMutual that prioritize policyholder dividends over shareholder returns, to the tech-forward wellness programs of Manulife’s John Hancock, the competition is offering distinct and compelling alternatives to the MetLife monolith.
This comprehensive analysis explores over MetLife’s most formidable competitors. It dissects their brand stories, their strategic advantages, and the specific ways they are maneuvering to capture market share from the New York-based titan in the evolving landscape of global insurance and asset management.
Top Competitors of MetLife
1. Prudential Financial
Website – https://www.prudential.com/
If MetLife is the “Workforce Ally,” Prudential is “The Rock.” Headquartered in Newark, New Jersey, Prudential Financial is arguably MetLife’s most direct peer in terms of structure, history, and market ambition. Like MetLife, Prudential has shed much of its volatile retail exposure to focus on steady, fee-based businesses like asset management (PGIM) and group insurance.
How They Compete with MetLife
Prudential competes through Asset Management scale and “Wellness” integration.
PGIM vs. MIM: While MetLife Investment Management (MIM) is a powerhouse in real estate and private credit, Prudential’s PGIM is one of the world’s largest asset managers, often dwarfing MIM in total assets under management (AUM). This scale allows Prudential to offer more competitive pricing on large-scale pension risk transfer (PRT) deals—where companies offload their pension liabilities to insurers.
The “Financial Wellness” War: Prudential was one of the first insurers to aggressively brand itself around “Financial Wellness” rather than just insurance. Their platform connects a company’s 401(k) offering directly with insurance products, creating a seamless ecosystem that MetLife’s “Upwise” platform is racing to match.
Recent Developments
In 2025, Prudential showed significant stock market momentum, outperforming the sector in “momentum scores” and stock price appreciation. Their aggressive expansion in emerging markets (Africa and Southeast Asia) provides them with a growth engine that offsets the mature US market, challenging MetLife’s own emerging market bets in Latin America and Asia.
2. Aflac
Website – https://www.aflac.com/
Aflac is a brand built on a brilliant marketing gimmick—the Aflac Duck—that turned a boring product (supplemental insurance) into a household name. However, behind the quacking mascot lies a financial fortress that generates the majority of its earnings not in the US, but in Japan.
How They Compete with MetLife
Aflac competes via Niche Dominance (Cancer Insurance) and the Japan Stranglehold.
The Japan Battleground: Japan is the second-largest market for both companies. However, Aflac is practically synonymous with “cancer insurance” in Japan, holding a massive market share. MetLife Japan competes here with foreign currency annuities and life products, but Aflac’s distribution network (selling through Japan Post and corporate payrolls) acts as a blockade to MetLife’s expansion in the supplemental health space.
The “Gap” Filler: In the US, MetLife sells “core” benefits (Life, Dental). Aflac sells “supplemental” benefits (Critical Illness, Accident). While they can be complementary, they increasingly compete for the same “payroll deduction” slot. Aflac is aggressively moving into dental and vision (via acquisition of Argus), directly attacking MetLife’s stronghold.
Recent Developments
Aflac has maintained superior profitability ratios (ROE/ROA) compared to MetLife throughout late 2024. Their strategy of “distribution expansion” in the US, moving beyond small businesses to large brokers (MetLife’s turf), signals a direct offensive to displace MetLife as the preferred supplemental partner for Fortune 500 companies.
3. New York Life
Website – https://www.newyorklife.com/
New York Life represents the “Old Guard” of insurance. As the largest mutual life insurer in the US, it does not have shareholders. It answers only to its policyholders. This structural difference is its biggest competitive weapon.
How They Compete with MetLife
New York Life competes on Trust, Stability, and the Agent Model.
Mutual vs. Public: MetLife, as a public company, is under constant pressure to deliver quarterly earnings growth. New York Life can take a 30-year view. They market this aggressively, claiming their decisions are made for the “long term security” of families, not Wall Street analysts. This resonates with conservative clients and wealthy individuals.
The Career Agent: While MetLife largely exited the “career agent” model (spinning off Brighthouse), New York Life doubled down on it. Their army of 12,000+ agents gives them a “last mile” advantage in the High-Net-Worth (HNW) market that MetLife cannot touch. If a client wants a complex Whole Life policy with dividends, they go to New York Life, not MetLife.
Recent Developments
In 2025, New York Life continues to dominate the “dividends” narrative, paying out record dividends to policyholders. This creates a “flywheel of trust” that makes their brand stickier than MetLife’s. They have also expanded their “Wealth Plus” capabilities, blending insurance with investment advice, challenging MetLife’s third-party distribution channels.
4. Manulife Financial / John Hancock
Website – https://www.johnhancock.com/
Based in Toronto, Manulife is a global giant that operates as “John Hancock” in the United States. They are a massive player in Asia, creating a direct clash with MetLife in the world’s fastest-growing economies.
How They Compete with MetLife
Manulife competes through Behavioral Insurance (Vitality) and Asian Scale.
John Hancock Vitality: John Hancock was the first to fundamentally change the life insurance product by partnering with Vitality. They offer significant discounts and rewards (like Apple Watches) if policyholders exercise and eat well. This “gamification” of insurance makes MetLife’s traditional term life policies look static and outdated. It appeals to the younger, tech-savvy demographic that MetLife is desperate to attract.
The Asia War: In markets like China, Hong Kong, and Vietnam, Manulife and MetLife are the two foreign heavyweights. Manulife’s digital-first approach in Asia (selling insurance via WeChat and banking apps) often outpaces MetLife’s more traditional bancassurance models.
Recent Developments
Heading into 2026, Manulife’s outlook focuses on “risk-managed strategies” and capitalizing on the “Great Wealth Transfer.” Their asset management arm is aggressively marketing sustainable investing (ESG), competing with MetLife’s MIM for institutional mandates in Europe and Canada.
5. Unum Group
Website – https://www.unum.com/
Unum is not a generalist; it is a specialist. It is the market leader in disability insurance in both the US and the UK. While MetLife is huge, Unum is the company that HR directors call when they have complex leave management needs.
How They Compete with MetLife
Unum competes via HR Tech Integration and Leave Management.
Total Leave Management: The modern HR director is drowning in compliance complexity (FMLA, state leave laws). Unum sells a “Total Leave” solution that handles the legal headache of employee absence. MetLife offers this too, but Unum’s platform is widely considered the “gold standard” for ease of use and integration with systems like Workday.
Mid-Market Dominance: While MetLife chases the “Jumbo” clients (10,000+ employees), Unum is incredibly sticky in the mid-market (500-2,000 employees). Their sales force is highly localized, allowing them to block MetLife from moving “down market.”
Recent Developments
Unum has successfully launched “Unum Behavioral Health,” a digital entry into the mental health space. By bundling mental health support with disability insurance, they are preventing claims before they happen—a value proposition that resonates deeply with employers in 2025, effectively countering MetLife’s 360Health initiatives.
6. Principal Financial Group
Website – https://www.principal.com/
Based in Des Moines, Iowa, Principal Financial Group has carved out a distinct identity as the champion of Small and Medium Businesses (SMBs). They focus heavily on retirement (401k) and benefits for companies that are too small for the big players to service effectively.
How They Compete with MetLife
Principal competes on SMB Specialization and Pension Risk Transfer.
The SMB Moat: MetLife’s systems are built for scale; Principal’s are built for flexibility. Principal wins by offering “big company benefits” to 50-person firms. Their 401(k) platform is integrated with payroll for small businesses in a way that MetLife’s institutional platform struggles to replicate.
Pension Risk Transfer (PRT) Tag Team: Interestingly, Principal and MetLife are often rivals and partners. In massive deals (like the $1.2 billion Philips North America deal), they sometimes split the liability. However, they fiercely compete for the lead role. Principal’s strength lies in administering complex, smaller pension plans, whereas MetLife prefers the massive, clean-cut liabilities.
Recent Developments
Principal has recently reorganized to integrate its asset management and retirement teams more closely. This “one firm” approach allows them to cross-sell deeper into their existing SMB client base, effectively locking MetLife out of the growing mid-sized business market.
7. Corebridge Financial
Website – https://www.corebridgefinancial.com/
Formerly the Life & Retirement division of AIG, Corebridge Financial is a newly independent giant (IPO in 2022). Unshackled from AIG’s property-casualty volatility, Corebridge is a laser-focused competitor in the annuities and retirement space.
How They Compete with MetLife
Corebridge competes via Annuity Distribution and K-12 Retirement Markets.
Variable Annuities: Corebridge is a top-tier player in variable annuities, a market MetLife largely exited to de-risk its books. For financial advisors looking for “growth-oriented” retirement income products for clients, Corebridge is a go-to partner, whereas MetLife offers more conservative “stable value” products.
VALIC (The Teacher’s 403b): Corebridge (through its VALIC brand) is a dominant force in the K-12 and healthcare retirement market (403b plans). This is a massive public sector niche where MetLife has a presence but lacks the dedicated, boots-on-the-ground dominance that Corebridge maintains.
Recent Developments
Since its spin-off, Corebridge has been aggressively partnering with asset managers like Blackstone to boost its investment yields. This allows them to offer higher interest rates on their annuities than MetLife, attracting yield-hungry retirees in the high-rate environment of 2024-2025.
8. Sun Life Financial
Website – https://www.sunlife.com/en/
Another Canadian powerhouse, Sun Life has aggressively expanded into the US, not by trying to be everything to everyone, but by buying up specialists. They are a top player in the US “Stop-Loss” market (insurance for self-insured employers).
How They Compete with MetLife
Sun Life competes on Medical Stop-Loss and Dental Power.
Stop-Loss Leadership: Many large US employers “self-insure” their health risks. They buy “Stop-Loss” insurance to protect against catastrophic claims (e.g., a $1M cancer treatment). Sun Life is the leader here. MetLife has tried to grow in this space, but Sun Life’s risk data and relationships give it the upper hand.
DentaQuest Acquisition: By acquiring DentaQuest, Sun Life became the second-largest dental provider in the US. This creates a direct duopoly with MetLife (the #1 dental carrier). Sun Life is aggressively using price and network access to steal MetLife’s “crown jewel” dental clients.
9. Voya Financial
Website – https://www.voya.com/
Voya Financial (formerly ING U.S.) has built its entire brand around the intersection of “Health and Wealth.” They realized early that an employee’s decision about Health Savings Accounts (HSAs) is linked to their 401(k) contribution.
How They Compete with MetLife
Voya competes through Integrated Decision Support Tools.
myVoyage: Voya’s digital app is widely praised for visualizing a user’s entire financial life—showing how spending on health insurance affects retirement savings. MetLife’s “Upwise” is a response to this, but Voya had the first-mover advantage in connecting the “Health” and “Wealth” silos.
Government Market: Voya is exceptionally strong in the government (457 plans) market. MetLife competes here, but Voya’s specialized administration platforms for state and local governments often win the RFP battles.
10. AIA Group
Website – https://www.aia.com/en
AIA is the largest independent publicly listed pan-Asian life insurance group. Born from the same root as AIG but now independent, it is focused 100% on the Asia-Pacific region.
How They Compete with MetLife
AIA competes on Regional Focus and High-End Agency.
The Premier Agency: In Asia, MetLife uses a mix of banks and agents. AIA uses a “Premier Agency” model—hiring only elite, highly educated agents who cater to the affluent. This allows AIA to capture the highest margin business in China and Hong Kong, leaving MetLife to fight for the mass-affluent segment.
China Expansion: As China opens its financial sector, AIA has been the fastest to secure licenses for new provinces. Their brand prestige in mainland China is arguably higher than MetLife’s, making them the preferred employer for top talent and the preferred insurer for the rising middle class.
Comparative Snapshot: MetLife vs. The Field
| Competitor | HQ Location | Primary Battleground | Competitive “Superpower” |
| Prudential | USA (NJ) | Asset Management / Group Life | PGIM Scale: Massive investment arm drives pricing power. |
| Aflac | USA (GA) | Japan / Supplemental Health | Brand & Network: The “Duck” brand and deep penetration in Japan. |
| New York Life | USA (NY) | Individual Life / HNW | Mutual Structure: Long-term focus creates deep trust with wealthy clients. |
| Manulife | Canada | Global / Behavior Tech | Vitality: Gamified insurance that appeals to digital natives. |
| Unum | USA (TN) | Disability / Leave Mgmt | HR Tech: Best-in-class leave management systems for complex compliance. |
| Principal | USA (IA) | SMB / Retirement | SMB Focus: tailored solutions for businesses <500 employees. |
| Corebridge | USA (TX) | Annuities / K-12 | Yield: Private equity backing allows for aggressive annuity rates. |
| Sun Life | Canada | Stop-Loss / Dental | Risk Niches: Dominance in self-funded employer risk (Stop-Loss). |
| Voya | USA (NY) | 401k / Health Accounts | Integration: Connecting health decisions (HSA) with wealth decisions (401k). |
| AIA | Hong Kong | Asia-Pacific | Elite Agency: Capturing the Asian High-Net-Worth market. |
Conclusion
In 2025, the competitive moat around MetLife is being tested not by a single “MetLife killer,” but by a swarm of specialized adversaries. While MetLife remains the “Carrier of Choice” for mega-corporations due to its sheer scale and reliability, it is losing ground on the edges. Unum is winning the war for HR efficiency; John Hancock (Manulife) is winning the war for consumer engagement; and New York Life retains the crown for individual trust.
To maintain its supremacy, MetLife’s “Next Gen” strategy must successfully bridge these gaps. It must become as technologically fluid as Voya, as nimble in the mid-market as Principal, and as dominant in asset management as Prudential. The future of the brand story will depend on whether MetLife can transition from being a payer of claims to a “partner in life”—a transformation that every competitor on this list is also racing to achieve. The winner will be the company that can best prove to the CFO that they save money, and to the employee that they actually care.
