Christie's and Sotheby's both increased buyer's premiums into 2026, and the move drew an unusual amount of pushback from a buying community that had largely absorbed the previous increases without protest. The headline change is small in absolute terms and large in cumulative effect. Buyer's premiums on the top tranche at the major houses are now structurally several points higher than they were a decade ago, and the cumulative cost on a multi-million-pound lot is meaningful.
The 2025 UBS / Art Basel Global Art Market Report flagged the buyer's-premium increases as a structural response to revenue pressure rather than a cyclical adjustment. The houses are doing it because they need to, not because the market is overheating.
What changed and by how much
The headline rates run on a tiered basis. The major houses charge a higher premium on the first tranche of the hammer price (the entry tier), a moderately lower premium on the second tranche (the mid tier), and a structurally lower premium on the top tier above a defined threshold. Each house has its own thresholds and rate schedule, and each makes the schedule public on the lot page.
The 2026 changes raised the entry-tier rate at both Christie's and Sotheby's by several percentage points, and modestly adjusted the thresholds. Phillips followed with broadly comparable adjustments. The effect on a typical mid-market lot is a higher total cost to the buyer; the effect on a trophy lot is smaller in percentage terms but still measurable.
Why the houses are raising premiums now
Three forces explain the timing. The first is the soft total-sales environment. The Hiscox Online Art Trade Report has tracked weakening dealer and auction sales through 2024 and 2025, and the major houses' published results have reflected the cooling.
Revenue per lot has compressed, and the premium is the lever the houses control most directly.
The second is the structural cost base. Marketing, catalogue production, specialist staff, and the increasingly competitive scramble for consignments have all pushed the cost base higher. The houses fund client services and the high-touch consignment process out of their commission margin, and that margin has been under pressure.
The third is the seller-side fee war. The major houses have been progressively reducing seller's commissions on top-tier consignments to compete for the best lots, and the buyer's premium has had to compensate.
The structure of the fee war
The seller-side picture is critical to understanding the buyer-side move. Major consignments now routinely clear at zero seller's commission, with the consignor often receiving an overage share of the buyer's premium above a defined threshold. The economics are openly disclosed in the published guarantee and consignment-terms language for major single-owner sales.
This has reshaped the houses' P&L. Revenue per lot increasingly comes from the buyer rather than the seller, and the houses' published year-end commentary has been explicit about the shift. The buyer's-premium increases are the visible end of an architecture that has been quietly moving in this direction for a decade.
How collectors are responding
The visible response has been a faster migration to private sales channels. The major houses' private-sale departments (Christie's, Sotheby's, Phillips) have all reported double-digit growth in private-sale volume year on year through the recent cycle, and the buyer's-premium structure on private sales is materially more negotiable than the published auction-room rates. Our coverage of why serious collectors are moving to private sales covers the dynamics in detail.
The other response has been a tighter focus on the trophy tier where the cumulative impact of the premium is structurally smaller in percentage terms. The pattern matches the broader resilience of the top of the market against the softening of the mid-tier. Our piece on auction-house results signalling a turning point reflects the same shift.
What it costs the buyer in practice
The cumulative cost can be material. On a hammer of $1 million, the premium structure at the major houses produces a total cost to the buyer in the high six figures of additional fees. On a hammer of $10 million, the figure runs into seven figures even at the lower top-tier rate.
That cost is structurally higher than the equivalent acquisition through a private sale, where the all-in fee is typically lower and more negotiable. The trade-off is the transparency, competitive bidding and immediate clearing that the public auction format provides, which private sales explicitly do not.
What this means for the houses' competitive position
The buyer's-premium increases are not a costless move. The houses are competing simultaneously with their own private-sale channels, with the major mega-galleries' direct-to-collector private sales, and with a growing online channel that has lower fixed costs. The 2025 UBS / Art Basel Global Art Market Report has tracked the share of dealer private sales as a growing slice of total trading volume.
The houses are betting that the trophy-tier consignment pipeline will hold, that the brand value of a Christie's, Sotheby's or Phillips sale is worth the higher buyer-side cost, and that the cumulative architecture of fee structure remains defensible at the top. The bet is logical; whether it holds through the next cycle is a different question.
What this means for collectors
The total cost of public auction acquisition has risen, structurally and meaningfully, over the past decade. Collectors building positions in 2026 should price the premium into the diligence at the bidding stage, evaluate the alternative channels (private sale, dealer direct, online viewing room) more carefully, and treat the published premium schedules as the floor rather than the ceiling of the conversation.
Our broader coverage of the art market trends defining 2026, the primary and secondary markets field guide and our piece on declining sales against persistent optimism all reflect a market in which the public-auction format is still essential but is no longer the only credible transactional path.
The premium increases are a structural response to a structural shift, and they are unlikely to reverse. Collectors should price accordingly.
Frequently asked questions
How much did buyer's premiums actually rise in 2026?
The major houses raised the entry-tier premium by several percentage points and modestly adjusted the threshold tiers. The published rate schedules are available on each house's website and on the individual lot pages. The cumulative effect on a typical mid-market lot is meaningful; the effect on a trophy lot is smaller in percentage terms but still measurable.
Why are the houses raising buyer's fees instead of seller's commissions?
The houses have been progressively reducing seller's commissions on top-tier consignments to compete for the best lots, and the buyer's premium is the lever the houses retain to fund client services, the high-touch consignment process, and the competitive cost base. The 2025 UBS / Art Basel Global Art Market Report has tracked the structural shift in detail.
Are private sales cheaper than auction for the buyer?
Typically yes, on an all-in basis, but the comparison is not direct. Private sales offer negotiable fees, less transparency on price discovery, no competitive bidding, and a slower clearing process. Public auction offers transparency, immediate clearing, and the documented record that supports long-term provenance and resale.
Each format suits a different acquisition profile.
Will the premium increases push collectors to other channels?
Some migration is already visible. Private-sale volumes at the major houses have grown materially year on year, and the mega-galleries' direct-to-collector private sales have expanded. The auction format remains essential for price discovery and trophy-tier sales; the broader transactional cycle is increasingly multi-channel.
