NinjaTrader-Alpha Futures Split Reignites Prop Trading Payout Concerns

The week opened with conflict at the heart of the retail prop trading sector. NinjaTrader, citing an alleged overdue payment, terminated its agreement with prop firm Alpha Futures. In a public response posted on X, Alpha disputed the claim, publishing invoices and payment records to demonstrate that payments were current. Alpha argued that NinjaTrader's real motivation was objection to Alpha's launch of a competing AlphaTrader platform. The termination left traders facing cancelled Premium accounts and unpaid payouts beyond those already distributed, igniting social media criticism and renewing concerns about payout security within the prop trading industry. Industry observers used the incident to question the long-term sustainability of evaluation-based prop trading business models—a reminder that traders' funds and access depend on maintaining good standing with a single platform provider.

Meanwhile, AI continued its expansion into trading platforms. FundedNext announced a Model Context Protocol server enabling traders to connect their accounts with AI assistants including ChatGPT, Claude and Gemini. The integration provides read-only access, allowing users to review account information, payouts, trading performance and applicable rules without permitting the AI to execute trades or modify account settings. Authentication is handled through OAuth 2.0, with passwords remaining within FundedNext's systems. The launch reflected the broader industry trend of integrating AI tools with trading platforms while maintaining operational safeguards.

On the traditional brokerage side, Plus500 reported first-half 2026 revenue of $462.9 million（約740億円）, up 12% year on year, while EBITDA edged just 1% higher to $187.5 million（約300億円）, reflecting increased client acquisition spending. Customer Income reached a five-year high of $460.8 million（約740億円）. Trading activity, however, slowed during the second quarter after a strong start to the year, and new and active client numbers softened between April and June. Plus500's non-OTC business, including its US futures operations, continued to expand and accounted for around 15% of group revenue. The broker maintained full-year guidance and ended June debt free with more than $850 million（約1400億円） in cash.

Brokers also continued to broaden their product offerings. Tickmill UK partnered with Interactive Brokers to allow eligible clients to trade stocks, ETFs, options, futures, bonds and other asset classes using Interactive Brokers' infrastructure, with Tickmill handling onboarding and customer support. Trading accounts remain with Interactive Brokers UK, which also handles execution, custody and account administration; Tickmill said the service uses Interactive Brokers' standard pricing without additional mark-ups, although it may receive volume-based compensation. The arrangement enables Tickmill to expand beyond its traditional forex and CFD business without developing its own multi-asset infrastructure. IG Group, meanwhile, proposed establishing a Jersey-incorporated holding company while retaining its London Stock Exchange listing and UK operations—a move reflecting broader trends as global firms seek greater flexibility for acquisitions and international expansion. IG is also exploring a possible US listing.

The week's dominant story—the NinjaTrader–Alpha Futures conflict—exposed a structural vulnerability in the retail prop trading ecosystem: traders' access to funds and trading infrastructure depends entirely on their relationship with a single platform provider, with no transparent recourse if that relationship breaks down. Alpha's public response, publishing payment records via social media, suggests that platform providers and prop firms increasingly resort to public disputes when private remedies fail. The controversy arrived amid broader industry growth: Plus500's first-half revenue of $462.9 million（約740億円） (up 12% year on year) and Tickmill's expansion into multi-asset trading signal active demand for trading services. However, the gap between Plus500's revenue growth (12%) and EBITDA growth (1%) reflects rising client acquisition costs—a sign that brokers are spending more to attract traders in a competitive market.

Regulatory and infrastructure trends complemented the week's commercial developments. FundedNext's AI integration follows similar moves by other retail brokers and reflects how AI tools are becoming embedded into trading workflows; by offering read-only account access through ChatGPT and Claude, the company addresses trader demand for AI assistance while preserving operational safeguards. Elsewhere, IG Group's proposal to establish a Jersey-incorporated holding company while retaining its London Stock Exchange listing illustrates how internationally active brokers are reshaping corporate structures to gain flexibility for acquisitions and cross-border expansion. In digital assets, Revolut advanced its UAE crypto launch after receiving in-principle approval from Dubai's Virtual Assets Regulatory Authority, and Malta began exploring a dedicated regulatory framework for prediction markets outside existing MiFID II derivatives rules—signaling policymakers' efforts to clarify rules for emerging asset classes.
