Venture Secondaries in 2026: The Allocations Guide to Record SPV Volume

Secondaries stopped being a workaround in 2026. With IPO windows still narrow and the largest private companies staying private longer, buying and selling existing shares has become the default liquidity path in venture, and SPVs have become the default wrapper for doing it.

Where the market actually is

US venture secondary transaction value reached roughly $112 billion in the first quarter of 2026. Annualized direct secondary value climbed from about $50 billion in late 2024 to $97.6 billion by March 2026, and global secondary volume across private markets is on pace to pass $210 billion for the year. Secondaries now rival IPOs and acquisitions as a source of venture liquidity.

Three things changed at once

• Tender offers became routine. SpaceX ran a $2.6 billion tender at a $1.25 trillion valuation in December 2025, OpenAI raised $6.6 billion at an $852 billion valuation in October, and Anthropic raised $5.5 billion in February 2026 at $380 billion.

• SPV formation exploded. Caplight data shows the number of secondary SPVs grew 545% over the last two years, while the total capital raised through them grew roughly 1,000%.

• Demand narrowed. Roughly 75% of carry-bearing SPVs tracked by Caplight sit in five companies: SpaceX, Anthropic, OpenAI, xAI, and Anduril. The market is deep, but it is not diversified.

What this means if you are leading a deal

The binding constraint has moved. Finding an allocation in a top private company is no longer the hard part; closing it before the seller moves on is. Three practical consequences follow.

• Speed decides who gets the block. Allocations in the most demanded names are committed in days. A vehicle that takes three weeks to form is a vehicle that loses the deal.

• Verify what is actually being transferred. Confirm the share class, the transfer restrictions, whether a right of first refusal has been waived, and whether the seller is delivering shares or a contractual interest in shares.

• Watch the fee stack. Layered vehicles can put two or three sets of fees and carry between your LPs and the underlying shares. Disclose the all-in number before the close, not after.

What this means if you are an LP

Four questions separate a clean secondary from an expensive one.

• What do I own? Shares held directly by the vehicle, an interest in another vehicle, or a contract on shares are three different risks.

• What is the all-in cost? Setup, annual administration, management fee, carry, and any spread between the seller's price and the price you are paying.

• How is the price justified? A recent tender price, a primary round, and a broker mark are not the same evidence.

• What happens at exit? Ask about distribution mechanics for cash and in-kind shares, and lockup exposure if the company goes public.

Where Allocations fits

Allocations runs the whole vehicle in one platform: entity formation, banking, KYC/AML investor onboarding, Form D and Blue Sky filings, capital calls, distributions including in-kind, and K-1 preparation. Pricing is flat and published, at $9,950 for a Standard SPV, with no platform carry. For secondaries that matters twice. The vehicle can form in minutes and close in days, and the cost of the wrapper is known before you commit to a seller.

Frequently asked questions

Is a secondary SPV different from a primary SPV? Structurally they are similar. The diligence differs: a secondary depends on the company approving the transfer, the share class being what the seller claims, and any right of first refusal being cleared.

How fast can a secondary close? Formation and investor onboarding can happen in days. The bottleneck is almost always company transfer approval, which sits outside the sponsor's control.

Why is volume concentrated in so few names? Because that is where investor demand is. AI and defense leaders have stayed private at very large valuations, so their shares are the ones buyers ask for by name.

Do LPs in a secondary SPV receive K-1s? Yes. The vehicle is a partnership, so each investor receives a K-1. On Allocations, tax preparation and K-1s are included in the flat fee rather than billed per investor.
