The 50/50 gallery-artist split: Founding myth or outdated model?

In 1958, Leo Castelli offered Jasper Johns, then completely unknown, an equal share of sales revenue. Johns was twenty-eight years old, had a modest studio in Manhattan, and his paintings of American flags looked like nothing else that was selling at the time. Castelli's gamble paid off: Johns's first exhibition sold out entirely, largely thanks to Alfred Barr's acquisition for MoMA. Both men became wealthy. And the 50/50 became a given — a tacit rule that would structure the primary art market for the next sixty years.

But a tacit rule is not a law of nature. And what the story of Castelli and Johns illustrates above all is less a philosophy of equity than a calculation of shared risk under very particular circumstances: a market in full expansion, modest operating costs, and a gallery that could genuinely make — or break — a career.

None of that holds true today in quite the same way.

A model born in a context that no longer exists

To understand why the 50/50 became standard, one must return to New York in the 1950s and 1960s. Art galleries there operated with a relatively lean cost structure: rents still affordable in neighborhoods like SoHo or the Lower East Side, teams of two or three people, communication built on word of mouth and a handful of influential critics like Clement Greenberg. International logistics were nonexistent or nearly so. No global art fairs to fund, no transatlantic insurance fees, no Instagram campaigns to orchestrate.

In that context, taking 50% of the sale price represented a comfortable margin that allowed the gallery to cover its costs while offering the artist a substantial share. Paul Durand-Ruel, the Parisian dealer who had supported the Impressionists in the nineteenth century, often worked with commissions of 30 to 40%. The shift to 50% in the mid-twentieth century was not trivial: it reflected a growing professionalization of the gallerist's role, which was becoming simultaneously that of agent, curator, press attaché and career strategist.

Paula Cooper Gallery, founded in New York in 1968 on a cooperative model, was one of the first to offer more favorable terms to artists — sometimes going as high as 60% for them in the early years, precisely because general overhead was deliberately kept low. This was not ideological generosity: it was economic coherence.

When art fairs changed the equation

The opening of Art Basel in 1970, followed by the creation of FIAC in 1974, gradually transformed the cost structure of galleries without the standard commission evolving in proportion. Participating in Art Basel Miami Beach or Frieze London now costs between 50,000 and 100,000 euros in booth fees alone, to which must be added the transport of works, insurance, accommodation for the team, production of visuals and installation costs. A mid-sized gallery can easily commit 150,000 to 200,000 euros per year to its participation in three or four international fairs.

This shift is fundamental. It means that the gallery's 50% no longer represents a comfortable profit but, for a mid-sized gallery with an annual turnover of one to two million euros, barely enough to survive after expenses. The Art Basel/UBS Global Art Market Report consistently identifies mid-sized galleries — those with annual sales of between 500,000 and 5 million dollars — as the most fragile segment of the primary market, the one with the highest rate of closures.

It is against this economic reality that some major galleries have begun renegotiating their terms. When David Zwirner, in a piece published in specialist online platforms in 2018, raised the idea that very large galleries might need to adjust their commissions upward, the reaction from the field was sharp. But Zwirner was pointing at something real: the growing gap between what the model promises and what it can actually deliver.

What the 50/50 actually conceals

The commission is rarely what it appears. In practice, the gallery-artist relationship covers very heterogeneous realities that the figure of 50% tends to flatten in a misleading way.

At a gallery like Hauser & Wirth or Pace, representing an artist means a considerable investment: production of museum-quality exhibition catalogues, placement at top-tier fairs, relationships maintained with international public institutions, loan management, and the tracking of private collections. The 50% taken on a work sold for 300,000 euros funds a real and measurable service.

For a more modest gallery taking the same commission on a canvas sold for 3,000 euros — meaning 1,500 euros net for the artist, before materials, studio costs and social charges — the equation is entirely different. The artist may have spent three weeks on that work. The gallery hung it on a wall, photographed it, posted it on Instagram and opened the vernissage on a Tuesday evening.

This is where the critique formulated by W.A.G.E. — Working Artists and the Greater Economy — becomes relevant. The New York organization, founded in 2008, campaigns for transparent and equitable compensation standards in the visual arts sector. W.A.G.E. does not call for the abolition of the gallery's commercial model, but for its legibility: that the artist know precisely what the gallery does with its commission, on what basis it is calculated, and what services it actually includes. W.A.G.E. certification is now granted to spaces that meet its compensation standards — a modest but meaningful signal of structural pressure toward greater transparency.

The clauses nobody talks about

Beyond the stated percentage, it is the ancillary contractual clauses that reveal the true balance of power. The right of first refusal obliges the artist to present every new work to their gallery before being able to sell it elsewhere. Territorial exclusivity can cover an entire continent. Some historical contracts, notably those associated with Mary Boone at the height of her gallery in the 1980s, stipulated a share in the artist's future income even after the commercial relationship had ended.

In France, the legal framework governing the gallery-artist relationship remains largely informal. Contrary to what one might expect, there is no mandatory standard contract. The Comité Professionnel des Galeries d'Art (CPGA) has published model representation contracts, but their adoption remains voluntary. Many relationships still rest on a letter of intent, or even a verbal agreement — terms that artists early in their careers, often without legal counsel, accept for lack of any negotiating leverage.

The question of the droit de suite — the artist's right to receive a share of resales on the secondary market — illustrates another fault line. In Europe, the 2001 directive guarantees artists between 0.25% and 4% of the resale price depending on the bracket, administered in France by the ADAGP. In the United States, no equivalent federal law exists. When a work by an American artist moves from 20,000 to 2 million euros between two auction sales at Christie's, the artist receives nothing — nor does the gallery that launched them. Only the selling collector pockets the capital gain.

The alternatives emerging, slowly

The eruption of NFTs in 2021 seemed, for a few months, to radically challenge the model. Beeple sold Everydays: The First 5000 Days for 69.3 million dollars directly through Christie's, without a gallery. Platforms like SuperRare or Foundation allow digital artists to sell at 85 or 90% commission for themselves, with the added benefit of automatic royalty mechanisms on secondary resales built into the smart contract.

But reality proved more nuanced. Most NFT artists who sought to cross the threshold of institutional legitimacy returned to gallery structures. Refik Anadol, a emblematic figure of generative art, works with institutions like MoMA while maintaining partnerships with commercial spaces. The gallery did not die: it proved difficult to replace in its function of cultural mediation and symbolic accreditation.

Intermediate models have nonetheless gained visibility. Some so-called second-generation galleries, like Company Gallery in New York or emerging spaces in Paris in the 18th arrondissement or in Pantin, work on a 40/60 basis in favor of the artist, keeping costs low by avoiding the most expensive fairs and betting on a tighter programming. Others are experimenting with monthly advances — close to the stipend system that Galerie Maeght once used with some of its artists — in exchange for a right of preemption on part of the artist's production.

What established artists understood long ago

It should be noted that artists with genuine market power have never really experienced the 50/50 as a fixed constraint. Damien Hirst bypassed his gallery by selling directly at auction through Sotheby's in September 2008 — the very day of the Lehman Brothers collapse — realizing 198 million pounds sterling. The affront was calculated, and it cost Hirst his relationship with Larry Gagosian, but it demonstrated that the 50% rule is above all a rule for those who have no other choice.

Tino Sehgal, for his part, adopted a radically different strategy: refusal of any written contract, refusal of any photographic or video documentation of his works, sales conducted verbally in the presence of witnesses only. His constructed situations nonetheless sold at museum prices, acquired by institutions such as the Guggenheim and the Tate. He did not withdraw from the market — he reinvented its protocols in a way that made any parasitic capture of value structurally impossible.

These strategies are obviously not within reach of a thirty-year-old artist trying to build visibility. Which brings us back to the central question: is the 50/50 inherently inequitable, or is it inequitable only when the gallery fails to do the work that justifies its share?

Toward a new contract between galleries and artists

The real question is no longer arithmetical. It is not so much the percentage that poses a problem — after all, a literary agent takes 15%, a music agent between 15 and 20%, and no one contests their usefulness — as the opacity of the service rendered and the absence of reciprocity in the relationship.

A healthier model would probably look something like this: a variable commission based on the gallery's actual level of investment, documented in a clear contract specifying the obligations of each party, with exclusivity clauses limited in time and geography, and a mechanism for sharing secondary market gains beyond a certain threshold. Some European galleries are beginning to work in this direction, often under pressure from artists who are better informed and less isolated thanks to professional networks and artists' unions.

The 50/50 model will not die by a single act of force. It will erode at the edges — in emerging galleries that cannot afford to practice it, among mid-career artists who have enough market presence to negotiate, in countries where legislation on artists' rights is more protective. What replaces it will probably not be a single figure, but a series of contractual models adapted to the reality of actual power dynamics and services genuinely rendered.

That would be, on reflection, the true heir to what Castelli proposed to Johns in 1958: not a percentage carved in stone, but an agreement between two parties who each have something real to bring to the table.
