The Fastest-Growing Insurance Lines in 2025 So Far: What Agencies Should Prioritize

Personal P&C premiums are growing significantly year-on-year. For fast-moving agencies, there’s an opportunity to create real growth by offering in-demand lines to their customers. However, with many smaller and mid-sized agencies lacking access to real-time data, identifying the most profitable areas for expansion can be tough. Missed opportunities, stagnation, or over-reliance on shrinking markets inevitably follow. Here, we take a look at some of the fastest-growing insurance lines of insurance to sell in 2025, and how insurance agencies can expand into new lines successfully with bolt’s platform to support them.

The Challenges in Navigating Insurance Market Shifts

Insurance agency growth isn’t just about writing more policies. It’s about writing the right policies, in the right markets, at the right time. Data from McKinsey & Company suggests P&C premium growth in 2022-2023 hit 9.5%, and more recent projected estimates suggest around 11% growth for 2025 in the US market.

Whether you’re wondering how to grow your insurance book of business, or simply looking to boost profitability in a hardening market, understanding the trends driving your customers is essential for growth.

However, independent and smaller agencies face three challenges that can derail that growth, even with a robust market behind them.

Limited Market Intelligence

Many agencies operate without real-time visibility into the lines experiencing the strongest demand or generating the highest profit margins. While industry reports are fantastic for uncovering broad trends, it’s that granular insight into each agency’s specific market and customer segments that truly drives informed expansion decisions.

Carrier Market Exits

With many standard carriers withdrawing from high-risk markets and challenging lines, a significant coverage gap is rising. At least 16 insurers have withdrawn from Florida since 2017, with others going insolvent, and major carriers have stopped writing new policies in California’s most wildfire-prone areas. These exits create opportunities for agencies that can access alternative markets. Many, however, lack the carrier relationships to fill these gaps.

Operational Complexity

Traditionally, adding new lines needs time-intensive carrier onboarding, often including separate quoting systems and additional training. For agencies with limited staff, this operational drag often stops them from moving quickly enough to capture emerging opportunities, especially if these fast-growing insurance lines need specialized knowledge or non-standard markets.

While these key issues can throttle insurance agency growth, finding the right support to offset them allows even the smallest agencies to build a more robust book of business and take advantage of the highest-growth products on the market.

Tracking the Trends: The Fastest-Growing Insurance Lines for 2025

Smart agencies are positioning themselves in the lines showing the strongest growth and most sustainable demand. Let’s look at a few areas where commercial property insurance trends and market growth suggest the opportunities are concentrated.

1. Personal Auto: Stabilizing After Record Growth

Personal auto premiums have seen significant growth over recent years, increasing by 20.6% between 2023 and 2024, with another strong rise anticipated this year. Market intelligence forecasts a combined ratio of 99 for 2025, with data suggesting a combined ratio of 99.2 in the US in the last year. While this shows a return to stability as markets adjust, it’s notable that telematics-driven products and usage-based insurance models are seeing strong adoption. This shift to more data-driven pricing models means opportunities for agencies able to offer sophisticated risk-assessment tools to younger demographics as well as fleet customers.

2. Cybersecurity: The New Must-Have Insurance Category

Recent data suggests that a massive 85% of large enterprises (more than 100,000 employees) carry some form of cyber policy. Current projections are that cyber insurance growth will rise from 2024’s $20.88 billion to $120.47 billion by 2032, with a CAGR of 24.5%. With so many larger entities already having cyber coverage, most of this growth will be driven by small and medium-sized businesses.

This makes cyber insurance growth one of the fastest-growing insurance lines on the market currently.

3. Commercial Property Insurance Trends: Surging in High-Risk Zones

Commercial property insurance trends also show dramatic rate increases in areas prone to catastrophe. Data suggests homeowners insurance premiums have surged in the last two decades, increasing by 39% over the last 7 years, and 15% in 2023 alone. In California, that jump is projected to cross the 20% threshold this year. The frequency of severe weather events shows no sign of decreasing – but the number of carriers willing to service these markets most definitely is.

For agencies looking to expand their insurance offerings, this creates opportunities to serve customers in these challenging markets, who often cannot access traditional and larger carriers.

4. Surplus Lines Insurance: Filling Standard Market Gaps

Those commercial property insurance trends point to another rising reality for insurance agency growth: standard carriers are retreating from challenging risks. This means surplus lines insurance and the E&S market now offer essential coverage for risks standard carriers won’t write, be it wildfire-prone properties or cyber protection for businesses. For carriers with easy E&S access, surplus lines insurance offers many opportunities.

Shifting Your Portfolio Intelligently

Successful insurance agency growth needs agencies to approach their portfolios strategically, ensuring every offering maximizes both customer value and agency profitability. However, that insurance agency’s growth needs to be approached systematically for maximum impact.

Introduce Complementary Coverage

Expanding your coverage for existing customers is infinitely simpler than acquiring and onboarding new accounts. That massive cyber insurance growth, in particular, offers opportunities for agencies to add high-value policies to their existing commercial accounts, creating natural cross-selling opportunities.

Targeting Underserved Markets

The spate of standard carrier withdrawals also creates new insurance agency growth opportunities for those able to access alternative markets. Commercial property insurance trends, in particular, are showing significant demand as standard carriers reduce their appetite. With surplus lines insurance access, smaller agencies can serve these challenging, but profitable, markets.

Leverage the Rate Environment

Likewise, a harder insurance market offers opportunities to improve customer relationships while still increasing revenue. Instead of just presenting renewal increases, agencies can better showcase their value by introducing additional coverages or improving the customer’s terms through alternative markets.

Expanding Access Efficiently

Traditional approaches to adding new lines, however, create operational bottlenecks that can inhibit growth and increase costs. Modern agencies need streamlined approaches that enable more efficient (and speedy) growth without getting bogged down in operational drag.

Here’s where a partner like bolt can significantly streamline your processes through:

Multi-Carrier Quoting: Rather than managing separate relationships across multiple carriers, agencies can use platforms like bolt that provide access to standard, non-standard, and specialty markets in a single, unified workflow. This allows agencies to quote even challenging risks quickly and effectively, while keeping customer service standards high.
Embedded Onboarding: Adding new carriers and new products has traditionally needed extensive paperwork and training, and even new systems. With a platform like bolt, however, carrier onboarding is handled behind the scenes, allowing agencies to expand their market access without adding yet another operational burden.
Automated Comparative Rating: Whether insurance agencies can expand into new lines efficiently depends on their ability to quickly identify the best markets for each risk. With automated comparative rating across multiple carriers built in, agencies can find optimal coverage and pricing, without the need for manual broker market submissions.

While offering new surplus lines insurance can be lucrative, the success of your expansion efforts hinges on finding ways to offer greater carrier access and expanded product lines smartly, rather than piling more work onto your plate.
