Cerebras Systems priced its IPO on May 14 2026 at a valuation near $56.4 billion. Before that, its stock changed hands mostly through secondary marketplaces, moving from an $8.1 billion valuation in a September 2025 Series G to about $23 billion five months later in its Series H, then more than doubling again at IPO.
That swing is exactly why accredited investors care about secondary marketplaces: getting exposure to a company like Cerebras before it lists means going through a platform matching private shareholders with buyers who meet SEC accreditation thresholds. This updated August 2026 guide will analyze and compare five of the leading marketplaces for accredited investors to purchase private stock.
1. Caplight
Pricing/Fees: Caplight isn’t a retail broker with a publicized commission structure; it is a data and derivatives technology and trading platform, pricing is negotiated per-transaction through its desk and no minimum is published.
Accreditation requirements: For an institutional investor, broker, or an accredited individual, Caplight uses its own set of criteria that assumes knowledge beyond SEC accredited criteria due to the use of derivatives and shorting.
Use Cases: Caplight is not used to buy and sell stock on a direct basis, it uses market pricing as its core strength. Its data and its MarketPrice model are regularly cited in business publications, and are a powerful pricing benchmark in direct secondaries, and when rights prevent direct access of a stock.
Cerebras specific-context: Caplight’s database followed Cerebras’ funding rounds as institutional customers used it to verify valuation which rapidly expanded by billions of dollars through to IPO. The platform has seen secondary volume over 50 percent year-over-year and more than $706M in funding in direct secondary markets.
Pros of secondary markets:
- Strength is transparency, capturing more than 10,000 privately traded share transactions.
Cons of secondary markets:
- Weakness is accessibility, not a platform where a first-time investor will log in to purchase shares.
Transaction Mechanics: Direct, negotiated secondaries with pricing used as the baseline reference point; synthetic derivatives that offer economic exposure without trading of shares.
Alternatives/Comparison Set: Hiive comes close to Caplight’s pricing discipline with a bit more of the execution framework you might expect at a private securities platform targeting accredited individuals.
2. Hiive
Pricing/Fees: Hiive displays its fees upfront with regularly provided updates on its LinkedIn page. Form CRS filed June 1st 2026, states that commissions range from 4.85% maximum for buyers to 5.75% for sellers, with lower percentages for larger trade sizes. Standard minimums are $25,000 though highly sought-after names may require from $100,000 up to $250,000 to exchange directly.
Accreditation Requirements: Buyers must self-certify as an accredited investor according to SEC’s Regulation D ($200k individually, $300k jointly – in the past two years income, OR over $1 million net worth, excluding property.) Some fund structures (marketed as Hiive Funds) require qualified purchaser status with $5million or more invested.
Use Cases: As shown by Hiive’s Cerebras Systems liquidity report, employees sitting on vested equity wanted cash before a listing that kept getting pushed back, and outside investors were seeking exposure to wafer a chipmaker’s business but did not want to have to wait years for a prospectus.
Cerebras-specific context: During 2025 and early 2026, Cerebras was among the names listed on private exchanges actively traded, and its evaluation continued to rise from $8.1 billion to $23 billion. Once the company listed the transactions were relocated to the public and ceased to be carried out on Hiive or any other private trading exchange.
Pros of secondary markets:
- Hiive includes around 3000 publicly traded securities, a monthly exchange of $300 million and live trade orders totaling $2 billion.
Cons of secondary markets:
- Hiive has an 18% right-of-first refusal exercise rate and a 72 percent company approval rate, meaning roughly three in ten deals stall at the issuers direction.
Transaction Mechanics: Buyers and sellers bid an offer anonymously through the order books and trades execute when bid and ask match. Hiive then facilitates company approval of the transfer, and any required ROFR, before the transaction settlement which it reports takes 30-60 days.
Alternatives and Comparison: Compared to Zanbato and Rainmaker, Hiive makes secondary markets more accessible for many accredited investors. Compared to Caplight, Hiive sells actual equity, not just data and derivative trades on such equity.
3. Clearlist
Pricing/Fees: Clearlist does not provide a retail price list. Owned for the most part by GTS, the biggest Designated Market Maker at the NYSE, its fees work much more like an institutional exchange than a per-share, per-trade commission.
Accreditation requirements: The company was established for individually accredited and institutional investors. Its initial backers clearly indicated a target client base for which an institutionally oriented system makes the most sense.
Use Cases: Clearlist positioned its initial platform as a system for late-stage private companies to test public market pricing. It encourages transactions for existing employees (through their options), not necessarily as an outright way to exit, but as a trial period before an IPO.
Cerebras-specific context: Cerebras was not a headline name on Clearlist, its public deal flow and volume disclosures are thinner than its competitors, making actual coverage of any single AI-chip name hard to verify.
Pros of secondary marketplaces:
- The backing from GTS gives Clearlist a fully fledged market-making infrastructure most rivals lack.
Cons of secondary marketplaces:
- The platform has published far less usage data than its competitors.
Transaction Mechanics: Through an order book-based system using GTS’s proprietary market-making algorithms, Clearlist pairs institutional and accredited investor buyers with sellers. Once orders are filled, each transaction must be subject to the typical company approval and transfer-restriction processes common in a private secondary trade.
Alternatives/Comparison Set: Investors looking for Clearlist’s market-maker foundation, but worried by its lack of recent volume disclosure, find that Rainmaker or Hiive fill that same spot on the spectrum.
4. Zanbato
Pricing/Fees: Zanbato offers an SEC-registered alternative trading system called ZX and does not list a fee card available to individual investors. Transactions are facilitated through a community of 100+ broker-dealer trading desks where prices are negotiated between banks.
Accreditation requirements: The Zanbato terms and conditions require membership with either accredited investor in regulation D, qualified purchasers, or qualified institutional buyers under Rule 144A, depending on the specific deal.
Use Cases: Zanbato’s ZXData product provides mark-to-market data and deal volume to assist funds with collateral and comparison, in addition to simply executing deals.
Cerebras Specific context: Trading in Cerebras secondary interest will come from these institutional desks, connected through Zanbato’s broker network, though Zanbato does not publish company-level trading volumes.
Pros of secondary markets:
- Allows access to true institutional liquidity as Zanbato has received $37.6 million in funding since 2010.
Cons of secondary markets:
- Fails to grant any ability for an individual accredited investor to easily sign up and place an order through a self-service model like Hiive.
Transaction Mechanics:
The trade will be routed through member broker-dealers, not a central order book. The broker will source counterparties to the trade, which will then pass through Zanbato’s crossing infrastructure once company approval and any right of first refusal waiver has been obtained.
Alternatives/Comparison set: Nasdaq Private Market’s institutional products provide the closest competition to Zanbato, whereas those who are pushed out of the brokerage model and individual accredited investors seeking to participate are likely to fall to Hiive or Rainmaker.
5. Rainmaker Securities
Pricing/fees: Rainmaker acts as FINRA-registered referral based broker/dealer. The platform connects buyers and sellers and gets paid when a deal closes, as opposed to simply an up-front platform commission fee structure. Arrangements are individually negotiated through its pool of independent brokers.
Accreditation requirements: Rainmaker works with institutions, private equity investors, high net worth individuals, and special purpose vehicles, and will qualify parties as accredited or qualified as applicable based upon structure prior to introducing buyers to sellers.
Use Cases: Rainmaker is best known as a sourcing tool: finding a network of buyers for late-stage private name companies to buy from selling early employees or investors. It reported 2025 transaction volume up 70 percent year over year.
Cerebras-specific context: Rainmaker’s broker network is the kind of channel that historically sourced supply in high-demand AI infrastructure names ahead of their IPOs, matching sellers seeking liquidity with buyers willing to wait out company approval, though the volumes per company name are not disclosed.
Pros of secondary market places:
- Supply can be identified through Rainmaker’s broker network that can be published to their network of buy-side and sell-side clients.
Cons of secondary market places:
- Pricing is less standardized than the price found on a platform that offers a posted bid price.
Transaction mechanics: Typically a transaction closes directly, with the buyer paying the cash for the price agreed upon, then the seller notifies the company that the intention is to transfer shares and the deal then awaits company approval. If this cannot happen directly, Rainmaker will structure a special purpose vehicle.
Alternatives/comparison set: If there is an investor that wants deal flow sources through a broker network with greater price transparency, Caplight or Hiive would be the likely places to go as a first stop.

Frequently Asked Questions
Can I still purchase Cerebras stock on the secondary market?
No, Cerebras had its IPO on NASDAQ on 14 May 2026, and its shares are not trading publicly, meaning pre-IPO Cerebras stock is no longer trading on secondary markets.
How much must I earn and be with to be an accredited investor?
Under Regulation D of the securities Act, you can qualify if your annual income is at least $200,000 ($300,000 jointly) for the previous two years, or if your net worth (excluding your home) is over $1 million.
Why are the fees on different secondary marketplaces so varied?
Varying fees come with different fee structures: order-book platforms like Hiive typically charge a percentage-based commission on executed trades. Broker-driven marketplaces like Rainmaker broker terms themselves, often negotiation per transaction. Private institutions like Zanbato and Caplight do not have publicized fee schedules, as clients negotiate individually.
Conclusion
The Problem: Navigating private secondary markets is complex. With varied fee structures, strict accreditation rules, high minimums, and unpredictable company approval rates, finding late-stage Pre-IPO liquidity or shares can feel overwhelming.
Key Takeaways:
Platforms like Hiive offer direct, order-book trading for individual accredited investors. Tools like Caplight and Xanbato serve as critical benchmarks and institutional networks, though they lack self-service access.
Next Steps:
- Ensure you meet SEC accreditation or qualified purchaser criteria.
- Decide whether you prefer direct equity ownership or pricing data and derivative exposure.
- Review fee schedules, minimum investment requirements, and approval rates before placing your first bid.
