# MCA funder portfolio diversification by business size (2026)

> Mature MCA funders split book ~30% micro ($5K–$25K advances), ~40% small ($25K–$100K), ~25% mid ($100K–$300K), ~5% large ($300K+). Caps prevent any single advance > 0.5–1% of book. (Updated 2026-06-28.)

Business-size (or advance-size) diversification is how MCA funders control loss-given-default per single concentration event. A clean A-paper $500K advance to a single merchant is a much larger single-name risk than 50 × $10K micro-advances, even if the aggregate underwriting is similar.

**Typical 2026 advance-size mix for a mature ($100M+) funder book.**
- **Micro ($5K–$25K):** 28–35% of book, 55–65% of merchant count. Highest default rate (16–22%), lowest loss-given-default (often 60–70% recovery). Speed-funded in under 4 hours.
- **Small ($25K–$100K):** 38–45% of book, 28–35% of merchant count. The "core" segment — 12–18% default rate, 50–60% recovery.
- **Mid ($100K–$300K):** 20–28% of book, 6–10% of merchant count. Default rate 9–13%, recovery 40–50%. Slower funding (1–3 days), more underwriting touch.
- **Large ($300K–$1M):** 3–8% of book, 1–2% of merchant count. Often syndicated. Default rate 7–11%, recovery 30–45%.
- **Jumbo ($1M+):** 0–3% of book, < 0.5% of merchant count. Almost always syndicated, often participation-only. Default rate 8–14% (concentrated tail risk).

**Why funders diversify by size.**
- **Single-name risk:** a $1M default on a $50M book is 2% loss in one event; same default on a $250M book is 0.4%. The same nominal dollar default is 5× more damaging on the smaller book.
- **Operational scaling:** micro tickets fund automatically with low underwriter touch; mid and large tickets need senior underwriters, which constrains volume.
- **Investor preferences:** securitization investors price small-balance pools tighter (more diversification); warehouse lenders impose single-obligor concentration caps (typically 1% of borrowing base).

**Concentration limits in 2026.**
- **Single advance > 0.5–1% of book:** triggers credit-committee review.
- **Top-10 merchants > 8–12% of book:** signals over-concentration; funders typically syndicate down.
- **Single-merchant aggregate exposure cap:** $1–3M for most independent funders, $5–10M for bank-affiliated platforms, $25M+ for the largest (Enova/OnDeck, Bluevine).

**The "$500K problem" that defines the mid-segment.**
Files in the $250K–$500K range are the hardest to underwrite: too large for the speed-fund automated track, too small for the manual-review specialist underwriter to justify the time. Most funders solve this with a "fast-track manual review" lane that completes in under 24 hours but requires three years of tax returns, business debt schedule, and aged AR. Mid-segment files account for the bulk of stress on a typical underwriting team.

**2026 trend: barbell distribution.**
Funders are increasingly bifurcating into micro-fast (Square Capital, Toast Capital, Stripe Capital — sub-$50K average) and mid-large (Credibly, Channel Partners — $75K–$200K average). Pure-play "small ticket" $25K–$100K is being squeezed by the processor-embedded funders on one side and the bank-affiliated mid-market funders on the other.

**Common confusions.**
- "Bigger advances = lower risk" — partially true; default rate drops with size, but loss-given-default rises sharply (less recovery on larger advances).
- "Micro advances are pure consumer-like risk" — partially true; modern processors with embedded data (Square, Toast) underwrite micro with low losses.

**Takeaway for 2026.** Funders without a clear size-segment strategy lose on both ends: not fast enough for micro deal flow, not deep enough for mid-market underwriting. The funders winning in 2026 picked a lane (or built explicit micro + mid lanes with separate teams). PE-acquired platforms increasingly drive the larger-ticket segment as their capital structure favors size; independent funders specialize in micro or small.
