Scale
Scale AI sells human data labeling and RL training data to AI labs, plus defense contracts.
Scale's commercial labeling business lost major AI lab customers right as those same labs start generating their own training data.
Scale AI trains artificial intelligence systems by having human workers label and organize data. The company was valuable because all the major AI labs trusted it as a neutral supplier, but that changed when Meta acquired 49% ownership in June 2025, which immediately blocked Scale from working with OpenAI, Google, Anthropic, and xAI. Rivals like Surge and Mercor are now winning contracts by staying independent. Beyond the independence problem, the whole business of human labeling is becoming less important as AI companies build synthetic data (fake training information created by AI itself) and learn through trial and error, which makes Scale's core service potentially obsolete. The one thing that could save Scale is if its defense and government work (a $500 million deal with the Department of Defense) grows fast enough to replace the business it is losing in the commercial world.
Scale's government/defense revenue share reported in 2026-2027 filings or press. Would show whether defense contracts are offsetting commercial losses.
Mercor or Surge AI closing a funding round above $10B valuation in 2026. Would show investors pricing rivals as the new leaders in Scale's place.

| Rival | Direction | Evidence |
|---|---|---|
| Surge AI | gaining on | Reportedly overtook Scale's 2024 revenue, seeking $15B valuation, as of June 2026 |
| Mercor | gaining on | Revenue grew from ~$500M annualized (Sep 2025) to ~$2B (Jun 2026), talks at $20B valuation |
| Handshake | gaining on | Pivoted into AI training data in 2025, scaling revenue rapidly through mid-2026 |
| OpenAI, Google, Microsoft, xAI (as departed customers) | losing to | All pulled back or cut ties with Scale after Meta's 49% stake, per June 19, 2025 report |
- Is Scale AI profitable in 2026?
- Scale AI has not disclosed profitability. It targeted roughly $2B revenue for 2025, but lost major customers including OpenAI, Google, and Microsoft after Meta took a 49% stake in June 2025, and cut 14% of staff in July 2025, suggesting margin pressure rather than confirmed profit.
- Who owns Scale AI?
- Scale AI is privately held. Meta Platforms invested $14.3 billion for a 49% non-voting stake on June 13, 2025, valuing the company at over $29 billion. Founder Alexandr Wang left to join Meta's superintelligence unit; Jason Droege became CEO while Scale says it remains independent.
- Is Scale AI losing customers to competitors?
- Yes. After Meta's June 2025 stake, OpenAI, Google, Microsoft, and xAI all pulled back or cut ties with Scale AI over conflict-of-interest concerns, per a June 19, 2025 Computerworld report, opening the door for rivals Surge AI, Mercor, and Handshake to gain share.
- Could AI replace Scale AI's core business?
- Scale AI's core human-data-labeling business faces displacement as frontier labs shift toward synthetic data and reinforcement-learning environments instead of static human annotation, a trend industry analysis flagged in a July 24, 2026 report on the AI training-data sector.
- Who is Scale AI's biggest competitor?
- Surge AI, Mercor, and Handshake are Scale AI's closest rivals in AI training data. Mercor's revenue reportedly grew from about $500M annualized in September 2025 to $2B by June 2026, and Surge AI reportedly overtook Scale's 2024 revenue while seeking a $15B valuation.
- Did Scale AI get any big government contracts?
- Yes. Scale AI won a $99M Army R&D contract in August 2025, and its Pentagon CDAO agreement, originally $100M, expanded to $500 million by May 6, 2026, per Bloomberg, giving it a defense foothold as commercial customers exited.
