Simon Tang at Accelex flagged the operational pressure point most secondaries allocators already know: the data layer is breaking. As secondaries volume crosses $150 billion annually and platforms proliferate beyond the traditional broker-dealer core, large allocators now manage exposure across fragmented position feeds with no standardized taxonomy. The consequence is not theoretical—reconciliation time has doubled at multi-platform shops in eighteen months.

The problem compounds at scale. A family office running secondaries exposure through four platforms receives position data in four different formats. NAV updates arrive on different cadences. Underlying fund-level transparency varies by GP relationship, not by contract. When secondaries become a liquidity management tool rather than an opportunistic sleeve, the administrative overhead moves from annoying to material. Tang notes that unstructured data—PDFs, email attachments, portal-only access—still represents the majority of position reporting at mid-sized platforms. The infrastructure assumes infrequent review, not daily risk management.

The timing matters because secondaries are shifting from niche to permanent allocation. Family offices are no longer treating secondaries as a liquidity escape hatch for legacy positions. They are constructing secondaries sleeves as deliberate portfolio components, often with 8-12% target allocations and quarterly rebalancing discipline. That operational cadence requires data infrastructure that does not yet exist at the platform layer. The gap is widest for allocators running both LP-led and GP-led transactions across multiple sponsors—each structure reports through different systems, and aggregation happens manually.

What gets missed in the growth narrative is the second-order effect on portfolio construction. When position-level data requires two analysts and three days to reconcile, allocators cannot rebalance dynamically. They lock into quarterly reviews, missing pricing dislocations that clear in four to six weeks. The shops that have built proprietary aggregation layers—typically the $3 billion-plus family offices with dedicated data teams—are now operating with a structural information advantage. They can see cross-platform pricing divergence that smaller allocators only discover in quarterly reports.

Allocators should monitor three developments over the next nine months. First, whether the largest secondaries platforms begin converging on ILPA-style reporting standards without regulatory pressure. Second, whether third-party data aggregators can build position-level reconciliation tools that work across the fragmented platform landscape. Third, whether the top fifteen secondaries advisors begin requiring standardized data formats as a condition of large mandates—that would force platform-level adoption faster than any industry working group.

The infrastructure follows the capital, not the reverse. As secondaries move toward $200 billion annually by year-end 2026, the platform operators will either build unified data layers or watch allocators consolidate toward the two or three platforms that do. The family offices that solve this now—either by building internal systems or by concentrating platform relationships—will have pricing visibility that others will not match for two years.
