Nike Still #1 in 2024 — How Shein’s Fast-Fashion Play is Closing the Gap on Adidas and Reshaping Sportswear by 2026

Nike leads global apparel market — but disruption looms

The sports-apparel and athleisure market is increasingly dynamic. In the traditional pecking order, Nike stands at the top. For fiscal year 2024, Nike reported full-year revenues of approximately US$51.4 billion, up modestly from the prior year. Meanwhile, Adidas reported full-year revenues of €23,683 million (≈ US$24–26 billion depending on FX) in 2024, representing an 11 % growth in euro terms and 12 % on a currency-neutral basis as per Adidas Report

Nike therefore retains a commanding lead in scale; Adidas is gaining momentum; and simultaneously, the fast-fashion giant Shein is emerging as a serious competitor in apparel overall — with implications for the sportswear incumbents. Let’s explore the breakdown, compare the players, dig into what Shein is doing right, and assess what this means for the sportswear industry in 2026.

Financial comparison: Nike, Adidas, other brands & Shein

Nike (FY2024):

• Revenues: US$51.4 billion.

• Net income: ~US$5.7 billion for FY2024.

• Footwear remains the dominant contributor, with apparel a meaningful but smaller share.

• In FY2025 ended May 31 2025, revenues fell to US$46.3 billion (~10 % decline) as the company undergoes realignment.

Adidas (FY2024):

• Revenues: €23,683 million (≈ US$24–26 billion) in 2024.

• Gross margin improved to 50.8 % in 2024 (from 47.5 % in 2023).

• Operating profit rose to €1,337 million in 2024 (vs €268 million in 2023) — a strong turnaround.

Shein (fast-fashion disruptor):

• Estimated revenue: ~US$22.7 billion in 2022; US$32.5 billion in 2023 (≈ 43 % growth).

• Some sources estimate full-year 2024 revenue at ~US$38 billion.

• Although Shein does not publish fully audited public results, this scale places it firmly into competition in the global apparel arena.

Other brands (brief snapshot):

• Lululemon: premium athleisure leader, revenues over US$10 billion by 2024 (exact numbers vary) — not purely “sports” brand but relevant in apparel/athleisure.

• Puma: in 2024 reported sales of ~€8.8 billion (≈ US$9–10 billion) and strong growth in lifestyle/fashion categories.

• Under Armour: smaller scale (~US$5–6 billion in recent years) and more challenged.

Key take-away: Nike’s scale is still unmatched among traditional sportswear brands, but the apparel share — especially non-footwear, trend/athleisure sectors — is under increasing threat from entrants like Shein. Adidas has made a strong rebound, but still trails Nike significantly.

Why Shein is closing in — what the disruptor does differently

Shein’s rapid ascent is not purely due to being low-cost. It’s about speed, agility, social-media native distribution, and catalogue breadth. These are structural advantages incumbents may have under-estimated.

1. Extreme SKU-velocity and trend-surfing

Shein reportedly introduces thousands of new SKUs weekly, using micro-testing and rapid produce---ship cycles. This contrasts with the traditional seasonal model of Nike, Adidas and others. The faster turnaround lets Shein capture fast-moving trends and shift inventory quickly — reducing risk of unsold stock and increasing responsiveness. Analysts cite Shein’s cycle as operating in days, not weeks.

2. Ultra-agile supply chain and low minimums

Shein’s verticalised Chinese supply base allows very short lead times, flexible order sizes, and nimble response to demand. Traditional sportswear brands, with long-cycle global manufacturing, may struggle to match that speed.

3. Social-commerce / influencer-first acquisition

Shein has built strong traction among younger Gen Z shoppers via TikTok, Instagram, creator “haul-culture”, and frequent collaborations. This creates high customer acquisition efficiency. By contrast, Nike and Adidas are stronger in performance marketing, brand equity and sport-heritage — but may not be as nimble in ultra-fast trend cycles.

4. Low-price, broad-range positioning into athleisure

While Nike and Adidas command premium pricing (especially for performance footwear), Shein competes on price and volume. Moreover, Shein is increasingly moving into “athleisure” and casual-active apparel — the crossover segment where sport performance and fashion meet. This is exactly the kind of territory that large sportswear companies used to dominate but now must defend on multiple fronts.

5. Direct-to-consumer, marketplace operations

Shein’s model is e-commerce native, global, app-centric, with lower fixed retail infrastructure and agile logistics. Traditional players are investing in DTC (direct to consumer) and digital channels, but legacy wholesale/retail structures and supply-chain complexity remain anchors.

Implication for sportswear incumbents: The threat is not just “cheap copy” apparel — it’s that apparel spend (especially among younger buyers) may be diverted to ultra-fast entrants rather than premium sports brands. That diminishes margin potential, brand loyalty and lifetime-value. Brands like Nike and Adidas must defend the performance side (where they have differentiation) and adapt the fashion/athleisure side to be faster, more trend-aware, and more value-competitive.

What this means for the sportswear industry going into 2026

a) Faster product cycles & “micro-drops” will become standard

Expect sportswear brands to accelerate their release cadence, lean into limited drops, leverage digital exclusives, and shrink lead-times. Adidas already emphasised in 2024 that its footwear-led growth (17 % currency-neutral in 2024) was driven by Originals, Football and Training segments. Nike’s direct business and wholesale must align to this faster rhythm.

b) Margin pressure on the apparel side

Footwear remains high-margin for Nike and Adidas, thanks to premium positioning, sports heritage and innovation (think Air, Boost, etc.). Apparel tends to have lower margins and faces higher price competition. With Shein and other fast-fashion entrants siphoning volume at lower price-points, the apparel portion of sportswear brands will face margin headwinds unless they successfully emphasise premium/lifestyle differentiation.

c) Channel convergence: Sport + fashion + DTC

Sportswear brands will increasingly intersect with fashion brands, lifestyle brands and e-commerce disruptors. The lines between “performance gear” and “casual lifestyle apparel” blur. Brands will also push more direct-to-consumer, agile digital experiences, engaging younger consumers via apps, social, and communities.

d) Supply-chain and cadence become competitive advantage

Speed to market, inventory flexibility, and demand sensing will increasingly matter. Brands that remain slow to respond may cede share in fast-moving segments. Meanwhile, sustainability, traceability and geopolitical risks (e.g., tariffs, trade-policy) are growing. For example, Shein is now facing regulatory scrutiny and import-tariff exposure in the U.S. and Europe.

e) Premium performance vs mass fashion segmentation

We will likely see clearer segmentation: (1) premium performance brands (Nike, Adidas, etc.), (2) fashion/athleisure trend players (including Shein), (3) hybrid/disruptor models. Each will adopt distinct value propositions. Sportswear incumbents will need to lean into their performance heritage while innovating quickly in apparel.

What the giants are doing (and must do)

Nike:
In FY2024, Nike grew revenues modestly (1 % currency-neutral) to US$51.4 billion, net income up ~12 % to US$5.7 billion. For FY2025 (ended May 31) revenues declined to US$46.3 billion (~10 % down) as the company executes a turnaround strategy under new leadership. Nike is emphasising its “Sport Offense” strategy: sharpen performance segmentation, clear inventory, realign digital channels and wholesale partnerships.

Adidas:
After the disruption related to its Yeezy collaboration, Adidas in 2024 achieved an ~11 % revenue increase to €23,683 million and operating profit of €1,337 million (margin ~5.6 %) — a strong rebound. Adidas is investing in Originals, Football, Training, and improved margins. Still, it must defend apparel/footwear share in the face of both Nike and faster moving fashion entrants.

Shein:
Shein’s estimated revenue ~US$32.5 billion in 2023 (up 43 % vs 2022) and possibly ~US$38 billion in 2024. Although many of its items are not performance-sportswear, its entry into active-lifestyle apparel and sheer scale mean that sportswear brands must pay attention. Shein’s model forces incumbents to rethink speed, cost, digital-first connectivity and consumer-segment velocity.

Key questions for 2026 and beyond

• Will Nike and Adidas regain apparel share lost to ultra-fast platforms?

• Can sportswear brands shorten their supply cycles and increase “drops” frequency without eroding margins?

• Will consumers increasingly buy “sporty apparel” from non-sportswear brands (Shein, fast fashion) and reserve sports brands for performance footwear/gear?

• How will sustainability, tariffs, and regulatory scrutiny affect fast-fashion disruptors — and can incumbents capitalise on that?

• Will footprint expansion, DTC digital acceleration and direct-to-consumer marketplace strategies determine winners in the next phase?

Summary and conclusion

Nike remains the leader in global sports apparel/footwear with revenues over US$50 billion in FY2024. Adidas is firmly in second place and showing strong growth, but the real story is the fast-fashion disruptor Shein, which has scaled ~US$30 + billion in apparel revenue and is increasingly encroaching on apparel/athleisure segments once dominated by sportswear brands.

The implications for 2026: sportswear brands must do more than compete on innovation and heritage — they must compete on speed, digital agility, supply-chain flexibility and value. Shein’s rise is a wake-up call: even premium sports brands are vulnerable in apparel if they don’t adapt their rhythm and model.

For consumers, that means more drops, more choice, sharper pricing; for investors, margin pressure in apparel is real, though performance footwear remains a strong hold. Ultimately, the winners will be brands that combine brand equity, product innovation, digital/consumer connection, and supply-chain agility.
