# Wolverine Trading Q4 2025: The $138B ETF-Led Strategy and Mega-Cap Conviction

> Wolverine Trading's latest 13F reveals a highly concentrated $138.7 billion portfolio led by a massive $15.8 billion stake in the SPY ETF and significant bets on NVDA and TSLA.

Market Liquidity and Systematic Scale Wolverine Trading, LLC, a key player in institutional market making and proprietary trading, has revealed a massive $138.73 billion US equity portfolio in its Q4 2025 13F filing. The portfolio's structure reflects the firm's role in providing liquidity and managing complex risk, with a heavy reliance on broad-market ETFs and high-volume mega-cap technology names. The SPY Backbone The defining feature of Wolverine's portfolio is its enormous stake in the SPDR S&P 500 ETF Trust (SPY). With a valuation of $15.80 billion, SPY accounts for nearly 12% of the firm's total reported assets. This concentration is typical of firms that utilize index-linked products to hedge various derivative and market-making activities, providing a robust, liquid foundation for the rest of the book. High-Conviction Tech Bets: NVDA, TSLA, and META Beyond its ETF core, Wolverine maintains significant direct exposure to the market's most liquid and volatile technology leaders. NVIDIA (NVDA) and Tesla (TSLA) hold the top individual stock positions, valued at $7.1 billion and $6.9 billion, respectively. Combined, these two names represent over 10% of the portfolio, signaling a massive focus on the AI and EV sectors as key drivers of volatility and trading volume. The Crypto Signal: MicroStrategy in the Top 10 In a notable tilt toward digital asset exposure, MicroStrategy (MSTR) has secured a position in Wolverine's top 10 holdings with a $2.93 billion valuation. Given MSTR's role as a proxy for Bitcoin performance, this position highlights the growing intersection between traditional equity trading and the crypto-economic landscape for large-scale institutional players. Trading Firm Dynamics Wolverine's Q4 filing shows a stable portfolio with 500 reported positions and minimal churn among its top-tier holdings. The top 10 positions account for 46.4% of the total portfolio value, reflecting a "barbell" strategy that pairs massive index liquidity with highly concentrated bets on sector-defining mega-caps.
