Magnetar Capital: Platform Profile

Overview

Magnetar Capital is an alternative asset manager founded in 2005. Its current platform spans quantitative hedge-fund strategies and alternative credit/fixed income, with additional sector-oriented investment activity.

The important distinction is between the Magnetar brand and the legal entities appearing in regulatory filings. The primary filing adviser for this review is Magnetar Financial LLC.

May fit better for

• institutional investors seeking multiple alternative-strategy sleeves;
• investors interested in quantitative arbitrage and alternative credit;
• allocators willing to evaluate private funds one vehicle at a time;
• investors comfortable with complex capital structures and nontraditional assets;
• users who can distinguish public AUM from regulatory AUM.

May fit less well for

• investors looking for a simple retail brokerage product;
• users expecting one firmwide minimum;
• investors who interpret low-correlation objectives as guaranteed diversification;
• users who treat every Magnetar legal entity as interchangeable;
• investors who rely on 13F data as the complete portfolio.

Current public AUM is $17B+

Magnetar's current first-party firm overview states:

• Founded: 2005
• Public AUM: $17B+
• Public AUM as of: 2026-03-31
• Full time employees: 221

Keep the date attached to the figure.

Regulatory AUM is $32.0B

Current Form-ADV-derived reference for Magnetar Financial LLC:

• Regulatory AUM: $32.0B
• Regulatory AUM as of: 2026-08-05
• Discretionary AUM: $30.7B
• Accounts: 72

The difference is not an error; the two measures use different definitions and dates.

Magnetar uses an umbrella/rather-than-one-entity structure

Current IAPD materials for Magnetar Financial LLC identify related/relying adviser structures.

Quantitative investing is a distinct strategy business

Current first-party quantitative materials identify:

• Systematic Risk Arbitrage: Yes
• Systematic Convertible Arbitrage: Yes
• Equity Statistical Arbitrage: Yes
• Systematic implementation: Yes

The firm describes these as diversifying return streams. Store:

• Guaranteed diversification: No
• Guaranteed low correlation: No

Alternative credit spans several underlying asset types

Current first-party materials describe investments across:

• corporate and structured credit;
• mortgages and real estate;
• consumer and specialty finance;
• transportation;
• entertainment-related assets;
• other opportunistic credit.

Q2 2026 13F value is $10.94B

Regulatory filings show:

• Q2 2026 13F value: $10.94B
• Q2 2026 13F as of: 2026-06-30

Private-fund minimums vary materially

Current Form-ADV-derived fund tables show minimums ranging from zero or internal/vehicle-specific values to six- and seven-figure amounts.

A zero minimum on a private-fund filing must never be presented as “$0 to invest with Magnetar.” Such figures can reflect internal, affiliated or operational structures.

Assessment

Magnetar's first-party $17B+ AUM and regulatory $32.0B AUM should both be preserved because they answer different questions. The public number is the firm's chosen current investor-facing measure as of March 31; the regulatory number is the later Form ADV measure.

The same discipline applies to the Q2 13F value. It is a holdings disclosure, not firm AUM.
