Artist Foundations’ Net Worth Has Nearly Tripled to $9 B., Led by Cy Twombly Foundation’s $1.5 B. in Art and Assets

New research from the Aspen Institute’s Artist-Endowed Foundation Initiative (AEFI) reveals that artist-endowed foundations in the U.S. now control roughly $9 billion in assets, nearly triple the $3.5 billion reported in 2011 and up 17% from $7.7 billion in 2018. The Cy Twombly Foundation leads with $1.5 billion in art and assets, followed by foundations for Alexander Calder, Joan Mitchell, Helen Frankenthaler, and Robert Rauschenberg, each holding over $500 million. The data, drawn from public tax forms, shows that just five of roughly 500 foundations account for more than half the total, with most established by postwar American artists born before 1931.

British billionaire's £200m art collection most expensive ever offered in UK

British billionaire Joe Lewis will sell a tranche of his art collection in a standalone sale at Sotheby’s in London this June, estimated at £150m–£200m. This makes it the most valuable single-owner collection ever offered in the UK, surpassing the Pauline Karpidas collection which totalled £101m. Highlights include Gustav Klimt’s *Bildnis Gertrud Loew* (est £20m–£30m), Amedeo Modigliani’s *Homme à la pipe* (est £12m–£18m), and Francis Bacon’s *Two Studies for Self-Portrait* (est £8m–£12m). The sale follows a smaller March auction of four works from the Lewis collection that focused on School of London artists.

The Venice Biennale’s Polite Fiction of Being ‘Above the Market’ Is Wearing Thin

The 61st Venice Biennale is underway, with art world figures flocking to Venice for the opening. While the Biennale is officially a non-selling curatorial platform, commercial interests are increasingly visible: galleries are funding artists' projects to recoup investments, auction houses like Christie's are hosting private selling exhibitions (including a 'Ghost Pavilion' at the Ca' Dario Palazzo), and fashion houses such as Bottega Veneta and Chanel are sponsoring events. Sotheby's has pulled support for the U.S. Pavilion, which is now crowdfunding, while Frieze is bankrolling the British Pavilion for a second time.

$60 M. Lichtenstein Comes to the Block at Christie’s, Potentially Joining His Priciest Works at Auction

Christie’s will offer Roy Lichtenstein’s 1964 painting *Anxious Girl* from the collection of legendary New York collector-dealer Holly Solomon and her husband Horace, with an estimate of $40–60 million. If it reaches its high estimate, it will become the artist’s second-priciest work at auction, trailing only *Nurse* (1964), which sold for $95.4 million in 2015. The work leads Christie’s 20th-century evening sale on May 18, amid a flurry of high-value consignments as both Christie’s and Sotheby’s aim to sustain momentum after posting improved 2025 results.

Artists Sell More Than $1 M. in Art at Sotheby’s in Support of a Debt-Free Yale MFA Program

A group of artists including Mickalene Thomas, Tammy Nguyen, and Richard Prince are donating works to a Sotheby’s contemporary art day sale next month, with proceeds expected to exceed $1 million. All funds will go toward making Yale University’s MFA art program tuition-free. The sale features works by Yale alumni both historical—Walker Evans, Josef Albers—and contemporary, such as Dominic Chambers and Do Ho Suh, whose $200,000–$300,000 piece is among the lots. The highest-estimated work is a Richard Prince photograph from his “Spiritual America” series, valued at $500,000–$700,000.

London Dealer Stephen Friedman Owes $10.6 M. to Dozens of Creditors, Including Artists Deborah Roberts and Kehinde Wiley

London-based gallery Stephen Friedman has accumulated debts of approximately $10.6 million, according to official documents filed with Companies House. Creditors include Coutts & Co. bank (£3.2 million), Pentland Group Ltd. (£1.4 million), the UK tax authority, the Pollen Estate, art logistics company Crozier, and several prominent artists—Alexander Diop (£341,905), Deborah Roberts (£289,232), and Kehinde Wiley (£163,849). The gallery closed its New York space in November 2024 after just two years, then abruptly shut its London location and entered insolvency proceedings in February 2025, shortly after pulling out of Art Basel Qatar. A restructuring proposal by FRP Advisory was approved on 22 April.

How Will the Venice Biennale Impact Alma Allen’s Market?

Artist Alma Allen has been selected as America's representative at the Venice Biennale, sparking controversy due to the unusual selection process under President Trump. The pavilion is commissioned by the newly formed American Arts Conservancy, led by Jenni Parido, who previously ran a pet food lifestyle shop and entered Trump's orbit through Mar-a-Lago pet charity events. Following the announcement, Allen's galleries Olney Gleason and Mendes Wood DM dropped him, but he was quickly picked up by high-profile gallery Perrotin. The article examines how the Biennale and its attendant drama might affect Allen's market, noting his longtime collectors include Beth Rudin DeWoody, Peter Morton, Jack Pierson, and others, while his auction prices have remained modest.

Is A Random Unknown Artist More Valuable Than Picasso? AI Thinks So.

An experiment using a custom AI model to evaluate artistic value independent of market context found that the model assigned a seven-figure price to an unknown street artist's work while valuing a Picasso at under $1,000. The project, run by an art journalist with a data scientist and an AI expert, trained a Fine Art Large Vision Model on millions of images and price data. Without metadata like artist name or gallery affiliation, the model's predictions were technically interesting but commercially useless; only when those market signals were added did predictions align with real auction outcomes.

Wildenstein dispute over Monet work highlights art market opacity

A long-running dispute involving the Wildenstein art dynasty has resurfaced over a 2004 transaction for Claude Monet's *Adolphe Monet Reading in a Garden* (1867). The painting was acquired by Guy Wildenstein through a €4.5m deal that included works by Pierre Bonnard and Alfred Sisley, among them Monet's *Marine, Amsterdam* (1874). That work was later resold via Christie's, but a 2020 sale attempt revealed that the original canvas had been lost during a transfer process, significantly reducing its value. Court-appointed specialists concluded in 2024 that the alteration predated the transaction and that the gallery likely knew of the damage. The sellers have filed a claim alleging "vitiated consent" under French law, with a court date set for 7 May in Rouen. The disputed Monet now reportedly belongs to billionaire Larry Ellison.

The Musée Fabre in Montpellier has acquired two 18th-century French paintings at auctions held by Artcurial in September 2025. The first is an "Allégorie de la Poésie" (1774) by Élisabeth Louise Vigée Le Brun, purchased for €250,000 with support from the museum's corporate foundation and a special grant from the Fonds du patrimoine.
