What is Megastudy's biggest risk?

The clearest risk is free AI tutoring apps like OpenAI's ChatGPT Study Mode and QANDA (Mathpresso), which now solve CSAT problems and explain answers at no cost, directly undercutting Megastudy's paid lecture packages. This pressure comes on top of Korea's shrinking student population, and together they have contributed to Megastudy's revenue declining for several consecutive periods through FY2025.

Is Megastudy in financial trouble?

Not in acute trouble, but the trend is negative: FY2025 revenue was KRW884.9bn, down 6.1% year-on-year, and operating income fell 2.1% to KRW121.0bn (both as of 2025-12-31). Parent MegaStudy Co. also posted a 5.2% revenue decline for FY2025, marking several consecutive periods of decline heading into 2026.

Is Megastudy at risk from AI?

Yes, partly. Free AI tutors such as Study Mode and QANDA are pulling students away with no-cost alternatives, but Megastudy's strong lecturer brand and content library, built around star lecturers who coach students for the CSAT, give it only partial overlap with what AI can replace, as of the July 2026 assessment.

Who are Megastudy's biggest competitors?

Within Korea's traditional hagwon industry, its main rivals are Digital Daesung and Sidae Injae, both indicted alongside Megastudy in the same exam-question scandal in December 2025. The newer competitive threat comes from AI-native tutoring products, OpenAI's Study Mode and QANDA, which undercut all three incumbents on price.

What should I watch to see if Megastudy is turning around?

Two dated events matter: MegaStudyEdu's Q2 2026 earnings, due 2026-08-14, will show whether the revenue decline of more than 4% year-on-year continues, and the exam-question trial involving lecturer Hyun Woo-jin is expected to reach a verdict by the end of 2026. Both outcomes are unresolved as of the July 2026 assessment and worth checking directly rather than assuming a direction.

How defensible is Megastudy's market position against new entrants?

Fairly defensible for now. Megastudy's lecturer network and scale, built over years as South Korea's dominant CSAT exam-prep company, would be difficult for new entrants to replicate quickly, and its content library and lecturer brand give it some insulation from AI substitution as of the July 2026 assessment. Even so, Korea's shrinking student population adds structural pressure on top of AI-driven substitution.

Losing its protection

The structural protection is eroding.

On the recordSince 31 July 2026 · Checkable from Q3 2026 · Every call on the record Checkpoint: Q2/Q3 2026 earnings filings to confirm whether Q1's near-flat revenue is real stabilization

The call

Megastudy stays profitable and pays out cash while a shrinking student pool and free state lectures chip at its core video-lecture business, with no AI-native rival yet in the market.

Megastudy sells video lessons from famous teachers to help Korean students prepare for exams. It is losing students because South Korea has fewer children being born, and those families can now use free government lectures from EBS or switch to AI tutors that adapt to each student instead of showing the same video to everyone. The company will only recover if it can attract adult learners, sell to schools directly, or if its star teachers sign long contracts that lock in customers and keep AI from stealing them away.

Why

AI pressure: AI-native adaptive tutor products (none yet launched in Korea's exam-prep market). No AI tutor has replaced packaged lecture videos yet, but personalized AI instruction sits directly on top of Megastudy's core product. Could AI do the core job? Yes, likely.

Bigger players: EBS (state-run broadcaster's free lecture arm). EBS already offers free or subsidized exam-prep lectures, competing directly with Megastudy's paid video model. Could a giant copy it? Yes, easily.

What protects it. Star-instructor brand recognition, large existing content library, and steady cash generation with high dividend payout.

What would change this call

Q2/Q3 2026 MegaStudyEdu revenue filings show flat or renewed decline. Tests whether Q1 2026's near-flat reading is real stabilization or a pause in demographic decline.
Launch of a Korean AI-native adaptive tutor product with measurable exam-cycle share gain. Would show the packaged-lecture model is being substituted, not just squeezed by demographics.
Government AI Digital Textbook (AIDT) rollout results and any B2G deals involving Megastudy or rivals. Indicates whether state-driven edtech displaces paid private tutoring volume.

Key numbers

FY2025 revenue KRW 884.9B, down 6.1% YoY (2026-05-12)
FY2025 operating income KRW 121.0B, down 2.1% YoY (2026-05-12)
Q4 2025 net income KRW 92.9B, up 85.3% YoY (2026-06-23)

Named risks

Shrinking South Korean school-age population reduces addressable market long term. Severity: high
AI-native adaptive tutors could substitute packaged video lecture model with no regulatory moat blocking entry. Severity: high
State-subsidized EBS and AI Digital Textbook program offer free alternatives to paid subscriptions. Severity: medium
Ownership uncertainty resurfacing after 2022 abortive MBK Partners stake-sale talks. Severity: low
Inconsistent third-party headcount data suggests limited visibility into workforce trends. Severity: low
