Drew Spaventa – Founder / CEO TSG Invest
TSG Invest said it has finished building out its Venture 50 roster and switched on a live index tracking 50 private companies it views as among the most closely watched candidates for future public offerings.
The Hauppauge, N.Y.-based firm said the final additions include Ramp, Kalshi and Saronic Technologies, giving the basket exposure across artificial intelligence, defense, fintech, biotech, robotics, space and energy. The company says the index is designed to give accredited investors a way to follow pricing and valuation trends in the late-stage private market.
The launch comes as interest in pre-IPO companies remains elevated, with TSG Invest itself publishing research this week on what it called a crowded 2026 IPO pipeline that could include names such as SpaceX, Cerebras Systems, Kraken, Revolut, OpenAI and Anthropic. That backdrop suggests the firm is trying to position the Venture 50 as both a research product and a market map for investors trying to anticipate the next wave of listings.
TSG Invest said the first version of the index will measure price changes at the individual company level and roll them up into sector performance. Later phases are expected to add pricing data from multiple secondary-market sources, which could make the benchmark more useful for investors trying to compare valuations across a fast-moving private market.
The company highlighted recent valuations for several additions, including Ramp at $32 billion, Kalshi at $22 billion and Saronic at $9.25 billion. Those figures reflect the scale of capital still flowing into a small set of private technology and defense names, even as the broader IPO market remains selective.
The firm has been expanding its wealth-management footprint alongside its research efforts. Last week, it said it opened a private wealth practice in Old Bridge, N.J., its third office, aimed at accredited investors and high-net-worth families.
The idea of a concentrated index is not new. S&P Dow Jones Indices, for example, already maintains a focused 50-stock benchmark for large-cap U.S. equities, a sign that investors continue to gravitate toward narrower baskets when they want a more targeted view of market leadership. TSG Invest is applying a similar concept to late-stage private companies, where pricing is less transparent and trading is more fragmented.
