Monitor Clear Street's next 13F filing for changes in its massive SPAC and speculative tech positions, which could signal a shift in risk appetite. The heavy concentration in mega-cap tech and crypto-related names means the portfolio is highly sensitive to macro and sector-specific news.
Price Chart
Executive Summary
Clear Street Group Inc. filed its quarterly 13F-HR for the period ending June 30, 2026, reporting a portfolio value of approximately $39.5 billion. The filing reveals a massive, highly diversified portfolio with a heavy concentration in mega-cap tech (NVIDIA, Microsoft, Apple, Amazon, Alphabet) and a significant number of SPAC holdings. Without prior quarter data, it is impossible to identify new positions, increases, or sector rotations, but the portfolio's composition suggests a focus on large-cap growth and speculative SPAC exposure.
