CHF 412.0M
Total Basel fair-week spend, isolated from Baselworld and Swissbau. ≈ CHF 58.9M/day across six days.
Art-Basel-only isolation. Captures only Tuesday–Sunday of fair week. Excludes Baselworld and Swissbau (which BAK Economics bundles into a single MCH Group number). Built from anonymous capture flow + hotel occupancy + restaurant POS partner data + retail card-spend partner data + civic-tax shoulder data, all k≥50 anonymized. Excludes capital goods (booth construction). Numbers are seeded; methodology is the deliverable.
What this replaces
"The BAK Economics MCH Group report bundles Art Basel revenue with Baselworld and Swissbau. No isolated number exists publicly."
— BAK Economics, Wirtschaftliche Bedeutung MCH Group (2023). Troviii's civic layer isolates the Art Basel number for the first time.

Bäckerei Kult, made measurable.
Which neighborhood merchant got fair-week traffic, year-over-year, traced back to the specific saved artist world that routed it.
bakery · Kleinbasel · Riehentorstrasse
Bäckerei Kult
Bz Basel (June 2023) documented Bäckerei Kult flipping from invisible neighborhood spot to fair-week destination after a single Art Basel guide mention. Troviii routes from saved artist worlds replicate the effect and make it measurable per-route.

Already a fair-week magnet. The Troviii layer adds attribution — Cafe Fruehling now sees which artist's saved world drove which surge, and the staff can prep for the rhythm.

Grand Hotel Les Trois Rois
Les Trois Rois is the canonical Art Basel hotel — a small but provable Troviii contribution via the carry-home commerce chips on artist world pages, attributable per-booking via referral parameters.

Anonymized at the merchant's request. The pattern matches: a Kleinbasel restaurant that became a fair-week destination because three different artist worlds route their visitors past it.

The named places, not the share %.
Above is the categorical SME share. Below is the named-merchant registry for this radius — pulled from a fair-week partner list and (when keyed) augmented live from Google Places. Each one anchors a real attribution loop back to a saved artist world or side-show route.

Side-show measurement · year-over-year
Beyeler, Schaulager, Kunsthalle, Liste, Basel Social Club.
Each satellite venue's fair-week footfall, the share that crossed over from Art Basel, and the share Troviii routed there.
| Venue | Fair-week footfall | YoY | Crossover with Art Basel | Troviii attribution |
|---|---|---|---|---|
Parcours · Art Basel public-art route alternative-venue Public-art route along Clarastrasse → Rhine. Troviii's primary capture node ('parcours-clarastrasse') sits here. ~47% of Parcours visitors save at least one node back into their thread. | 22,100 | +18% vs Parcours 2024 | 100% | 47% |
Basel Social Club alternative-venue Alternative venue producing the strongest YoY growth. Troviii captures ~41% of attendees as also-saved-an-artist-world — the wedge for emerging-collector retention. | 6,200 | +58% vs BSC 2024 (first full year) | 92% | 41% |
Schaulager museum Bridget Riley study room programming made it the fair-week destination for Riley-curious collectors — the same thread the Selma capture (Loop 1) routes into. | 11,800 | +34% vs Art Basel 2024 | 61% | 32% |
Kunsthalle Basel kunsthalle The 'After Op' group show is the named exhibition Troviii routes to in Selma's interpretation card. Visible spike in the during-fair pulse. | 9,400 | +22% vs Art Basel 2024 | 54% | 28% |
Fondation Beyeler foundation The single largest non-fair side-show destination. Troviii's expanding-show chip on artist worlds routes ~19% of attendees here; the rest is owned-channel + concierge. | 28,400 | +11% vs Art Basel 2024 | 78% | 19% |
Liste Art Fair satellite-fair Liste is the emerging-gallery satellite that runs Tuesday–Sunday alongside Art Basel. Troviii attribution is lower because Liste already has its own audience; the lift is concentrated in the Statements-curious overlap segment. | 19,600 | +8% vs Liste 2024 | 81% | 14% |

Methodology + k-anonymization + partner data sources
Methodology
All counts k≥50 anonymized. No PII captured or rendered. Merchant attribution requires either (a) merchant POS partner integration, (b) merchant opt-in to be named, or (c) k≥50 aggregate without naming. Year-over-year baselines built from Troviii's prior-edition saved data plus public BAK + Hotelverein figures. Federal visibility from public press monitor.
Pause / re-approach / capture-share is the same k≥50-floor anonymization used for gallery dashboards. Merchant attribution requires either merchant opt-in to be named, POS partner integration, or k≥50 aggregate without naming.
