The Two Sigma PhD Fellowship 2027 is one of the most competitive and fully funded industry fellowships for PhD students in the United States. Offered by Two Sigma — one of the world’s leading quantitative investment and technology firms — this fellowship provides exceptional financial support, a dedicated research mentor, and recognition to doctoral students driving breakthrough research in STEM. If you are a PhD student in computer science, applied mathematics, statistics, physics, or finance, this is one of the highest-value fellowships you can target this fall.
What makes the Two Sigma PhD Fellowship stand out from other funded PhD programs is its extraordinary financial package. Recipients receive up to $75,000 per year for two consecutive academic years, paid directly to their university to cover tuition, fees, and living expenses, plus a personal one-time cash award of $10,000. This places it among the most generous fully funded STEM fellowships for PhD students in the USA, rivaling top programs from Google, Bloomberg, and the NSF. Unlike many fellowships, students apply directly — no university nomination required.
This complete guide covers everything you need to know about the Two Sigma PhD Fellowship 2027, including the full benefits package, eligibility criteria, eligible research areas, required documents, and a step-by-step application walkthrough.

Why Apply for the Two Sigma PhD Fellowship?
The Two Sigma PhD Fellowship is one of the very few industry fellowships where the financial award rivals or exceeds what most universities pay for a full funded PhD package — and it comes on top of any existing university funding. For PhD students in machine learning, AI, quantitative finance, statistics, and computational research, this fellowship provides both the resources and the industry connection to accelerate a research career.
Two Sigma is not a traditional company. It is a data and technology-driven research organization that employs more scientists and engineers than finance professionals. The research mentorship that comes with this fellowship connects you to one of the most rigorous quantitative research environments in the world. Fellows and runners-up have gone on to top faculty positions, leading AI research labs, and senior roles at the most selective employers in quantitative finance and technology.
Crucially, this fellowship does not require a university nomination. Unlike the Google PhD Fellowship or many other prestigious awards, you apply directly. This removes the bottleneck of departmental quotas and gives every qualifying PhD student an equal shot regardless of how many other students in their department are applying.
How to Apply for the Two Sigma PhD Fellowship 2027
Follow these steps to submit a strong application when the 2027 cycle opens in August 2026.
- Monitor the official page — Visit twosigma.com/graduate-students/phd-fellowships regularly from July 2026. Based on prior cycles, the application portal opens in mid-August. Set a reminder so you do not miss the opening.
- Confirm your eligibility — Verify that you will be entering at least your 3rd year of PhD study with at least 2 years remaining when the fellowship begins in fall 2027. Check that your research aligns with one of Two Sigma’s eligible disciplines.
- Draft your research proposal now — The 500-word research proposal is the most critical component of your application. It must clearly describe your research area, explain its significance to the field, and articulate its relevance to Two Sigma’s work. Start drafting before the portal opens — strong proposals take multiple revisions.
- Update your CV — Ensure your CV is current, includes your full contact details, and highlights your publications, conference presentations, and research outputs. Submit it as a PDF with the correct naming format.
- Contact your referees early — Inform your thesis advisor and second referee now that you intend to apply. Give them as much advance notice as possible. Reference letters are submitted confidentially through a separate link after you submit your application — remind referees to check spam folders for Two Sigma’s email.
- Prepare your transcripts — Gather your unofficial graduate transcripts and combine them with your CV into a single PDF as required.
- Submit your application — Submit all materials through Two Sigma’s online application portal before the deadline. Based on the 2026 cycle, the deadline fell in late September. Apply as early as possible — do not wait until the final days.
- References deadline — After you submit, your referees will receive an automated email requesting their letters. Based on prior cycles, referees have approximately 5 to 6 weeks after the application deadline to submit their letters. Confirm with your referees that they have received and responded to this email.
