How AI Search Is Recommending Student Loan Refinance: Monthly Trends

Executive Summary

SoFi remains the category leader for student loan refinance recommendations, and it strengthened that position in October 2026. Valid recommendation coverage for SoFi reached 71.7% of qualified observations, up 10.6 points from the August 2026 baseline of 61.1%. That puts the gap between SoFi and second-place Earnest at 3.9 points, as Earnest also gained ground.

Earnest posted the strongest statistically significant gain in the series, rising 7.8 points from 60.0% at baseline to 67.8% in October 2026. Its advance from the immediate prior month was larger still, up 11.5 points from 56.3% in September 2026. SoFi's month-over-month move was similarly sharp: up 12.6 points from 59.1% in September. Together, the top two brands account for the bulk of this month's category movement.

PNC Bank was the only brand the benchmark flags as a significant decliner. Its coverage fell 2.4 points from 3.8% at baseline to 1.4% in October 2026, driven mainly by a contraction in raw presence. Citizens continued a quiet two-month rise, up 5.4 points from 25.9% at baseline to 31.3%, while ELFI, LendKey, RISLA, Laurel Road, MEFA, and Splash Financial all moved within the normal range of month-to-month variation.

Each monthly run begins with 800 prompt-surface observations (574 unique questions in October 2026, versus 562 in August 2026 and 570 in September 2026) across the benchmark's defined AI/search surface universe. Of those, 800 mentioned a tracked brand or competitor in each month; 561 were relevant and 239 were irrelevant in October 2026, compared with 594 relevant and 206 irrelevant in September 2026 and 588 relevant and 212 irrelevant in August 2026. The public metrics use the 438 qualified observations in October 2026, 455 in September 2026, and 447 in August 2026 that survive both qualification stages.

Key Findings

AI Response Inconsistency Alerts

Questions This Section Answers

• Which refinance pricing claims are AI platforms giving borrowers conflicting answers on?
• Where are AI platforms divided on borrower eligibility requirements for student loan refinance?
• Which brands had product availability or bonus terms contradicted across AI platforms?

The benchmark detected 32 critical or high-severity factual inconsistencies across five AI platforms: ChatGPT, Copilot, Gemini, Google AI Mode, and Google AI Overviews. The conflicts cluster around refinance pricing, borrower eligibility requirements, and product availability, and they matter commercially because they touch the questions borrowers ask before they choose a lender.

SoFi

AI platforms provided conflicting information about SoFi's variable APR range. When asked "What are the current refinance rates for student loans?", Copilot stated 5.99% to 9.99%, while Google AI Overviews stated 5.74% to 10.99%, citing Bankrate, Navy Federal Credit Union, and SoFi. A flagged source page on CollegeWhale showed both figures in the same excerpt, which may explain the divergence. Gemini separately returned 5.74% to 10.99%, sourced from Bankrate.

Responses differed on SoFi's fixed APR range as well. Copilot stated 4.24% to 9.99%, Google AI Overviews stated 6.08% to 9.99%, and ChatGPT stated 3.99% to 10.99%, citing NerdWallet and the Wall Street Journal. When asked "Who has the best refinance rates for student loans?", ChatGPT stated SoFi's lowest advertised fixed APR was 3.99%, while Gemini stated 4.49%, citing College Investor, Money, and Credible. The ranges do not overlap.

Platforms also provided conflicting information about SoFi's starting APR. When asked "Which bank has the lowest interest rate on a personal loan?", Gemini stated starting rates as low as 6.99% APR with discounts, citing Wells Fargo, Bankrate, and TD Bank, while Google AI Overviews stated rates start at 5.95% fixed APR, citing Wells Fargo, Truist, and U.S. Bank. A flagged NerdWallet source showed an estimated APR of 6.99% to 24.99%.

Conflicting information extended to SoFi's fixed refinancing APR. When asked "What is the best company to consolidate student loans?", ChatGPT stated fixed refinancing rates start around 3.99%, citing the Federal Student Aid student loan calculator, SoFi's own rates page, and NerdWallet, while Copilot stated a fixed APR of approximately 5.24% to 9.99%, citing FinanceSmartUSA, TheTopTens, and CollegeFinance. Flagged sources on the latter two pages showed figures of 5.24% and 5.99%.

Borrower eligibility requirements also differed. When asked "Is SoFi a good option to refinance student loans?", Gemini stated SoFi typically requires a credit score of 700 or higher, citing EducationData, Credible, and Bankrate, while Copilot stated the minimum is around 620, citing SparrowFi, the Wall Street Journal, and Student Loan Sherpa.

On the SoFi $400 checking bonus, platforms disagreed about the direct deposit requirement. When asked "Which banks are currently offering a $400 bonus for checking accounts?", Gemini stated a tiered bonus based on total direct deposit within a 25-day window with no specific dollar threshold, citing CreditDonkey and Chase. Copilot stated the offer requires direct deposits of $5,000 or more within 25 days, citing Forbes Advisor, College Investor, and BankBonusWizard. Flagged sources from College Investor, Finder, and WalletGrower support the $5,000 threshold interpretation.

Earnest

AI platforms provided conflicting information about Earnest's fixed APR range. When asked "What are the current refinance rates for student loans?", Google AI Overviews stated 3.95% to 4.20%, while Gemini and Google AI Mode both stated 4.45% to 9.99%, citing Bankrate and Navy Federal Credit Union. A flagged Navy Federal source page showed 4.45% to 11.25%, supporting the higher starting figure.

Responses differed on Earnest's lowest advertised fixed APR. When asked "Who has the best refinance rates for student loans?", Copilot stated 4.45%, citing EKD, MarketReview, and U.S. News, while Google AI Mode and Google AI Overviews both stated 3.75%. ChatGPT stated 4.45%, citing NerdWallet and College Investor, and Gemini stated 4.35% to 4.45%, citing College Investor, Money, and Credible. Flagged sources from Navy Federal and College Investor support the 4.45% figure.

Borrower eligibility requirements also diverged. When asked "Who can I refi my private student loan with if I didn't finish college?", Gemini stated Earnest generally requires a FICO score of 700 or higher, citing Student Loan Planner, Credible, and Tate Law, while Copilot stated approximately 650 or higher. When asked "What is the best company to refinance student loans?", Copilot stated a minimum credit score of 650 to 665, while Google AI Overviews stated 670 or higher, citing Earnest's own site and ELFI. A flagged LendKey source showed a minimum of 650.

On consolidation pricing, Copilot stated Earnest's fixed APR at approximately 4.99% to 9.74%, citing FinanceSmartUSA, TheTopTens, and CollegeFinance, while Google AI Overviews stated fixed interest rates start around 3.95% to 4.49% with autopay discounts, citing SoFi, Earnest, and ELFI. Flagged sources on the lower figure showed 4.99%.

PNC Bank

AI platforms provided conflicting information about whether PNC Bank currently offers student loans. When asked "Which banks have student loans?", ChatGPT stated PNC Bank offers private student loans in some circumstances, citing NerdWallet, CNBC, and CBS News, and both Google AI Mode and Gemini stated PNC offers private student loans to bridge funding gaps, citing NerdWallet, Forbes, U.S. News, and PNC's own site. Google AI Overviews stated the opposite: that PNC Bank discontinued accepting new student and education refinance loan applications, citing Credible, Citizens Bank, and Commerce Bank.

Conflicting information also appeared on PNC pricing. When asked "Which bank has the lowest interest rates for personal loans?", Gemini stated starting rates around 6.99% APR, citing Wells Fargo, Forbes, and Discover, while Google AI Mode stated rates start around 7.89% to 8.14% depending on zip code. A flagged NerdWallet source showed an estimated APR of 6.99% to 24.99%.

Responses differed on instant deposit fees. When asked "What banking apps deposit checks instantly?", Gemini stated funds are available immediately before 10:00 PM ET with no extra fee, though certain accounts may incur a fee, while Copilot stated a $2 fee for deposits of $25 to $100 and a 2% fee for deposits over $100. A flagged Finder source supported Copilot's fee structure.

LendKey

AI platforms provided conflicting information about LendKey's fixed APR range. When asked "What are the current refinance rates for student loans?", ChatGPT stated 4.39% to 9.24%, citing NerdWallet and the Wall Street Journal, while Gemini stated 3.98% to 9.24%, citing Bankrate. When asked "Who has the best refinance rates for student loans?", ChatGPT stated LendKey's lowest advertised fixed APR was 4.39%, while Copilot stated 3.98%. A flagged College Investor source supported the 3.98% figure.

Splash Financial

AI platforms provided conflicting information about Splash Financial's fixed APR range. When asked "What are the current refinance rates for student loans?", Copilot stated 3.99% to 11.24%, citing College Investor, CollegeWhale, and 5GigBucks, while Google AI Mode stated 3.99% to 10.24%, citing SoFi, Navy Federal Credit Union, and Earnest.

Benchmark Context

Questions This Section Answers

• How does the qualified benchmark set differ from the raw collection universe?
• Why did the qualified observation count contract between August and October 2026?

The report separates the raw collection universe from the qualified analysis set. Brand-level recommendation percentages are calculated within the qualified benchmark set.

The qualified observation count contracted by 17 month over month from September 2026 (455), and by 9 against the August 2026 baseline (447), as a higher share of collected prompts fell outside the vertical's topic scope.

Benchmark-Level Metrics

The share of answers that took a recommendation-shaped form rose sharply, as did the share that produced a valid recommendation shortlist. October's prompt mix produced more direct recommendation lists and fewer factual or pricing-oriented responses. September 2026 sat between these two readings, at 44.6% recommendation-shaped and 58.9% valid shortlist share, confirming that the shift was a steady climb across the quarter rather than a single-month spike.

AI Recommendation Trend

Questions This Section Answers

• Which student loan refinance brands gained or lost recommendation coverage this quarter?
• Which coverage movements exceeded normal month-to-month variation?

Coverage by Brand

SoFi and Earnest each exceeded normal month-to-month variation on this metric, and PNC Bank fell below its own typical range. The category-level movement is the combination of two large upward shifts at the top of the field and one small-count decline at the bottom, with the seven remaining brands moving inside expected variation.

What Changed This Month

Questions This Section Answers

• What drove SoFi's coverage gain to 71.7% in October 2026?
• How did Earnest reverse its September decline and move up the rankings?
• Why does the benchmark flag PNC Bank's decline as significant?

SoFi: Leader Extends Its Cushion

SoFi's coverage climbed 10.6 points from 61.1% at the August 2026 baseline to 71.7% in October 2026. The move against the immediate prior month was larger still: up 12.6 points from 59.1% in September 2026. This is the sharpest single-month gain of any tracked brand, and it restores separation at the top of the category.

Every supporting placement metric moved with it. Raw presence rose from 94.2% at baseline to 97.7%, meaning SoFi appeared in 428 of 438 qualified observations in October 2026. Top-three placement rose 13.5 points from 49.7% to 63.2%, and rank-one appearances rose 9.3 points from 27.5% to 36.8%, or from 123 to 161 observations. Net sentiment ticked up from 0.7 to 0.8.

The distinction to notice is that SoFi's gain came from both presence and placement, not from one alone. The brand is visible in nearly every answer and is now recommended near the top of the list in roughly two of every three qualified observations.

Highest-priority diagnostic: Which surfaces and prompt types are converting SoFi's near-universal presence into rank-one placements, and what evidence sources are anchoring those answers?

Earnest: Second Significant Mover, Placement Up Sharply

Earnest's coverage rose 7.8 points from 60.0% at the August 2026 baseline to 67.8% in October 2026. The prior-month comparison is more dramatic: up 11.5 points from 56.3% in September 2026, making October a clean reversal of September's decline.

Raw presence was essentially flat across the series, at 92.4% at baseline and 92.5% in October 2026, so the gain did not come from appearing in more answers. It came from placement. Top-three rate rose 8.8 points from 47.6% to 56.4%, while rank-one rate slipped slightly, from 17.2% to 16.2%, or from 77 to 71 observations.

Earnest's average recommended rank shifted from 2.17 to 2.25, still the second-closest-to-top average position in the category, behind SoFi. The brand is being recommended more often and more prominently in aggregate, even as its share of outright first-place answers eased slightly.

Highest-priority diagnostic: Which surfaces drove Earnest's top-three placement expansion, and is the small rank-one decline concentrated in a specific prompt type?

Citizens: Quiet Two-Month Rise Continues

Citizens rose 5.4 points from 25.9% at the August 2026 baseline to 31.3% in October 2026, a move the benchmark classifies as inside normal variation. Its prior-month comparison was a further 2.7 points up from 28.6% in September 2026, giving the brand a two-month upward streak.

Raw presence edged up from 43.6% to 45.0%, enough to carry the coverage change. Top-three rate rose 2.2 points from 9.2% to 11.4%, and rank-one rate rose 1.0 point from 1.3% to 2.3%, or from 6 to 10 observations. Net sentiment held at 0.7.

The distinction to notice is that Citizens converted a modest presence gain into a larger coverage gain. Its top-three and rank-one placements both improved, unlike several mid-field brands whose presence held but whose placement softened.

Highest-priority diagnostic: Which prompts moved Citizens into top-three positions, and what evidence sources are supporting those answers?

PNC Bank: Significant Decline in a Small-Count Window

PNC Bank's coverage fell 2.4 points from 3.8% at the August 2026 baseline to 1.4% in October 2026, a movement the benchmark flags as significant. The prior-month comparison was a further 0.1 points down from 1.5% in September 2026, extending a two-month downward streak. Valid recommendations stood at 6 observations in October 2026, down from 17 at baseline.

The decline was driven by raw presence, which fell 4.6 points from 7.6% to 3.0%, or from 34 to 13 observations. Rank-one rate was flat at 0.0%, and net sentiment eased from 0.6 to 0.5.

PNC Bank operates in a small-count window, so shifts of a handful of observations register as large percentage movements. The presence decline of 21 observations accounts for nearly all of the coverage change. The AI Response Inconsistency Alerts section above shows a related pattern: platforms are split on whether PNC Bank still offers student loans at all, a disagreement that may sit behind the presence contraction.

Highest-priority diagnostic: Which prompt categories stopped mentioning PNC Bank, and is the platform-level disagreement on product availability concentrated on those prompts?

ELFI: Third Place Holds, Coverage Flat Against Baseline

ELFI's coverage slipped 0.9 points from 38.3% at the August 2026 baseline to 37.4% in October 2026, within normal variation. The prior-month comparison was a 4.9-point recovery from 32.5% in September 2026, so the brand has regained almost all of September's decline.

Raw presence declined 3.2 points from 54.1% to 50.9% across the series, but top-three rate rose 3.6 points from 20.8% to 24.4%, and rank-one rate eased from 0.9% to 0.7%. Net sentiment edged up from 0.7 to 0.8.

The distinction to notice is that ELFI lost raw presence while gaining placement. The brand is appearing in fewer answers but is being recommended more prominently within the answers where it does appear.

Highest-priority diagnostic: Which surfaces are responsible for ELFI's presence loss, and which prompts are carrying its top-three gains?

Splash Financial: Stable Coverage, Presence Tight

Splash Financial's coverage held essentially flat, up 0.1 points from 14.1% at the August 2026 baseline to 14.2% in October 2026. Its prior-month move was a 1.2-point gain from 13.0% in September 2026. Raw presence eased 0.2 points from 23.7% to 23.5%, and top-three rate rose 1.2 points from 5.4% to 6.6%. Rank-one rate fell 0.9 points from 1.1% to 0.2%, or from 5 to 1 observation.

This is the profile of a brand whose overall standing is silent this month. The small rank-one decline sits inside a single-observation window and does not change its category position.

Highest-priority diagnostic: Which prompts surface Splash Financial in the answer without placing it among the top recommendations?

RISLA and LendKey: Middle-Field Coverage Holds

RISLA's coverage fell 1.0 points from 19.0% at the August 2026 baseline to 18.0% in October 2026, after a 2.6-point recovery from 15.4% in September. LendKey's coverage fell 0.5 points from 19.7% to 19.2%, after a 1.6-point recovery from 17.6% in September. Both moves sit inside normal variation. RISLA's rank-one rate fell to 0.0% from 0.4% at baseline, or from 2 to 0 observations, and LendKey's rank-one rate rose to 0.2% from 0.0%, or from 0 to 1 observation.

Highest-priority diagnostic: What separates the prompts where RISLA and LendKey remain recommended from those where they now appear only as mentions?

The Widening SoFi Gap: A Category Repositioning Observation

The widening coverage gap between SoFi and three mid-field brands is a category-level pattern rather than a single brand's problem. Against PNC Bank, the gap widened 13.0 points across the series, reaching 70.3 points by October 2026. Against RISLA, it widened 11.6 points to 53.7 points, and against ELFI, it widened 11.5 points to 34.3 points. All three gaps widened every month of the series.

Highest-priority diagnostic: Which prompt categories drive SoFi's separation from the mid-field, and where do those same prompts still return a mid-field alternative?

Buyer-Intent Interpretation

Questions This Section Answers

• Which buyer-intent clusters produced qualified observations in October 2026?
• What can the benchmark not say about pricing transparency and head-to-head lender comparisons?

In October 2026, all 438 qualified observations fell into the brand recommendation class. No observations qualified into pricing and value or multi-brand comparison clusters. The public benchmark therefore measures which lenders AI systems recommend for student loan refinance, but it cannot yet speak to how those systems handle pricing transparency, cost trade-offs, or direct head-to-head comparisons between lenders. That gap is notable this month, because the AI Response Inconsistency Alerts above show that platforms are giving borrowers materially conflicting pricing answers on five of the ten tracked brands, and the qualified benchmark does not capture those questions. Resolving them requires a company-level analysis that isolates pricing and comparison prompts specifically.

Brand Opportunity Summary

• Which student loan refinance brands need the most attention based on their October 2026 coverage?
• What priority diagnostic does the benchmark flag for each tracked brand?

The benchmark identifies where attention is warranted; a company-level analysis is needed to explain why.

Evidence Behind the Benchmark

The aggregate metrics are built from prompt-level observations capturing the query, the AI surface that generated the answer, whether a recommendation occurred, the rank of any recommended brand, the sentiment of the response, and citations where exposed. Company-level analysis can go deeper into prompt, competitor, surface, and evidence patterns to understand why AI systems recommend some lenders over others. Source presence is not automatically treated as proof of causation.

About This Benchmark

Report-Specific Interpretation Notes

• Several brands in this vertical operate with small observation counts, so percentage movements can appear large even when the absolute number of recommendations changed by only a handful. PNC Bank, MEFA, Laurel Road, and RISLA all fall into this window.
• The qualified denominator (438 observations in October 2026) is smaller than the raw collection universe (800 prompts), because only prompts that were relevant and delivered a usable AI answer enter the public metrics.
• Month-over-month movement identifies changes worth investigating; it does not by itself establish the cause of those changes. Directional analysis requires prompt-level review.

Next Step

The Public Benchmark Shows Where a Brand Is Winning or Losing. A Company-Level Audit Shows Why.

Beneath the aggregate percentages sit the questions that drive commercial outcomes: which high-intent prompts a brand wins, which competitor takes the recommendation when a brand loses, what attributes AI systems associate with each lender, and which external sources shape those answers. This month's benchmark shows SoFi and Earnest pulling away from the mid-field and PNC Bank contracting, but the public percentages cannot identify the prompts, competitors, or sources behind those results.

A company-specific AI visibility audit maps those prompt, surface, competitor, ranking, sentiment, and evidence-source patterns into a prioritized visibility strategy. It answers the "why" behind the movement and identifies the specific levers that can improve a brand's standing in AI-driven recommendation.
