Top 5 IndyCar Sponsorship Agencies: Indy 500 Reach for Brands Entering US Open-Wheel Racing

IndyCar is the most direct open-wheel route into the US market. FOX broadcast 18 IndyCar races in 2026 at an average of 1.68 million viewers per race, up 23% on 2025. The 110th Indianapolis 500 averaged 6.6 million viewers and peaked above 8.3 million, and the 2025 race sold out with a crowd of 350,000.

The best IndyCar sponsorship agency does two jobs. First, it tells a brand honestly whether IndyCar fits its US objective before any shortlist is built. Second, it provides negotiation support for sponsorship contracts once a team, driver, or Indy 500 package is chosen. Agencies tied to a single team will point every brand toward the same answer.

This guide covers the top 5 IndyCar sponsorship agencies, the ways into the series, what each tier costs, and how to match an IndyCar sponsorship agency to your budget.

5 leading motorsport sponsorship agencies for global brands

Five agencies stand out for a global brand weighing multiple series. The order below reflects independence, cross-series depth, and the ability to protect the buyer's spend from a first shortlist through final ROI reporting.

1. RTR Sports Marketing: independent brand-side motorsport consultancy

Best for: International and US brands that want independent advice on whether IndyCar sponsorship fits, followed by contract negotiation and activation through the Indy 500 and the wider season.

RTR Sports Marketing is an IndyCar sponsorship agency built on an independent, brand-side model, founded in 1995 by Riccardo Tafà and headquartered in London. Brands looking to hire sports marketing consultant for motorsports sponsorships with cross-series scope get an advisor that sits on the buyer's side of the table and never takes a fee from a team, series, or property.

RTR works across F1, MotoGP, NASCAR, IndyCar, WEC, Formula E, WorldSBK, and the Dakar Rally. That coverage is what makes it a strong first call for brands still choosing a series, because it can tell a brand honestly which series fits before a shortlist is built.

RTR Sports Marketing works to three principles:

Independence: no team stake, no series contract, and no commission from the property being sold to the brand.
Verticality: motorsport only, which is where the relationships and pricing knowledge sit.
Transparency: fee-based and open, with no hidden commissions and a clear line between advisory-only and full-service work.

For an IndyCar program, RTR covers the full lifecycle: testing IndyCar against other series, shortlisting teams or Indy 500 packages, negotiation support for sponsorship contracts, activation at the chosen rounds, and ROI measurement built on independent third-party data that a CFO will accept.

Full-service scope is staffed in-house, covering B2B hospitality, content rights, driver access, exclusivity enforcement, and field monitoring on race weekends. Brands do not need to pair RTR with a separate activation partner.

Negotiation support is central to how RTR earns its fee. The team has 30 years of pricing data across those eight series, and that data feeds an independent brand-side advisory model that a broker tied to one team cannot match.

2. Leonard Motorsports Marketing

Best for: brands entering NASCAR or a US-heavy motorsport portfolio through a team-side broker with deep Cup Series relationships.

Leonard Motorsports Marketing is a US firm known for NASCAR Cup Series and Xfinity Series deal flow. The firm has placed primary, associate, and contingency sponsors onto competitive teams and works closely with several ownership groups in the paddock.

Leonard Motorsports Marketing is strongest when a brand has already decided on NASCAR and needs quick access to available inventory. The firm is less cross-series than a consulting model. Buyers weighing multiple series should confirm whether Leonard Motorsports Marketing can compare NASCAR against F1 or IndyCar with the same independence as a firm without team relationships. Fee structure should also be clarified up front, since team-side brokers can carry commission arrangements a buyer-side model would not.

3. Sullivan Worldwide Marketing Group

Best for: US brands that want a domestic partner with a long record in American motorsport sponsorship.

Sullivan Worldwide Marketing Group is a Daytona Beach-based agency whose motorsport clients have included NASCAR and the Indianapolis Motor Speedway. It handles strategy, contract work, and activation, and suits brands that want a US-rooted partner with Speedway experience.

Buyers should ask whether Sullivan Worldwide Marketing Group's recommendation set is limited to properties it already works with, and whether it can compare IndyCar against series like F1 or WEC with the same depth.

4. Trackside Agency

Best for: brands with a signed deal that need trackside activation, hospitality delivery, and guest program management across US motorsport rounds.

Trackside Agency is a motorsport marketing firm active across NASCAR, IndyCar, and sports car racing in North America. The agency handles activation, hospitality build-outs, and driver appearances. It has executed programs at Indianapolis, Long Beach, Daytona, and the road courses on the US calendar.

Trackside Agency's strength is on-site delivery. Brands with an existing sponsorship who need better weekend execution use Trackside for hospitality, signage, and guest programs. The firm is positioned less as a negotiation-led advisor and more as an activation partner once the deal is done. Brands still choosing a series should pair Trackside with a buyer-side advisor upstream.

5. Bernstein Partners

Best for: US consumer brands that need fast access to IndyCar or Indy 500 inventory and are comfortable with a broker-style model.

Bernstein Partners is a US sports marketing firm with long-standing relationships across IndyCar teams and the Indianapolis Motor Speedway. The firm has worked on primary and associate placements for consumer brands entering the Midwest market through the Indy 500.

Team-side deal flow gives brands quick access to available liveries and hospitality slots, especially in the weeks before the 500, when demand peaks. Brands weighing IndyCar against other series should pair Bernstein Partners with a cross-series advisor, since firms with team relationships can carry commission arrangements that a fully independent model would not.

The ways into IndyCar Sponsorship

IndyCar teams are independent commercial entities that sell their own inventory, while the series manages series-level partnerships. That gives brands six routes in:

Car or livery sponsorship: logo placement on the car, from associate positions to full primary livery.
Driver sponsorship: placement on the driver's suit and helmet, prominent in interviews and podium moments.
Team sponsorship: a broader deal with the team, covering car, driver, team apparel, and digital channels.
Event sponsorship: naming or presenting rights for a race, including the Indianapolis 500.
Series partnership: championship-level association, including the series title held by NTT.
Technical or official supplier: product integration tied to a technical category, often with category exclusivity.

The Indy 500 is the single biggest lever. A single-race program there, whether livery, event presence, or hospitality at the Speedway, can carry a US brand campaign well beyond May if content and hospitality are planned around it.

How to match a motorsport sponsorship agency for global brands to your budget

Match the agency to the scope of the deal, not the other way around. An entry-level Indy 500 associate deal needs a fast, well-connected partner. A multi-year primary program needs negotiation support for sponsorship contracts and independent valuation.

Indicative IndyCar cost tiers, to verify with the agency before signing:

Associate / entry-level: $30,000 to $500,000. Single-race or season-long small positions on the car or suit, with limited activation and no category exclusivity.
Team sponsorship: $500,000 to $15 million per season. Primary or associate car and suit positions, full-season activation, hospitality access, and category exclusivity options.
Indy 500 and event sponsorship: $500,000 to $20 million+. Race naming or presenting rights, trackside branding, and hospitality.
Series-level sponsorship: $10 million to $20 million+ per season. Championship naming rights, broadcast integration across every race, and series-level exclusivity.

These tiers move with team performance, demand, and inventory. The best IndyCar sponsorship agency will hold current pricing benchmarks and flag when a quoted number sits outside the market.

Ask for the fee model too. Fixed advisory fees, monthly retainers, and success-based components all appear in agency contracts. An agency that discloses its full fee is the cleanest option for a finance team signing off on the spend.

Final take

The right IndyCar sponsorship agency for a brand entering US open-wheel racing is the one that stays on the buyer's side from first shortlist to final ROI report. Start conversations well ahead of May, because Indy 500 inventory is the most contested in the series.
