SizeProp — Crypto Prop Trading Backed by Pudgy Penguins

Table of Contents

SizeProp is a cryptocurrency-focused proprietary trading firm utilizing the order books of Hyperliquid and Trade.xyz. Instead of depositing personal capital, traders who pass an "evaluation challenge" starting from $33 are entrusted with up to $100,000 in funded capital and can receive up to 95% of the generated profits in USDT. This operational framework, paired with backing from Igloo Inc. (the parent company of Pudgy Penguins), has drawn significant market attention.

However, the proprietary trading model does not mean "zero personal funds = zero risk." There is an upfront cost in the form of evaluation fees, and even after passing, traders remain bound by strict liquidation rules defined in the terms of service. This article outlines SizeProp's trading structure, fee model, collaboration with Pudgy Penguins, and the essential risks to understand before participating—explained clearly even for those new to prop trading.

Project Overview

The starting point to understanding SizeProp is recognizing that it is neither an exchange nor an airdrop project; it is a prop firm that "lends" funded capital to traders. Instead of exposing their own capital to market risk, users pay an evaluation fee to pass a challenge and secure a funded account. Let's first review the foundational information below.

Payout CurrencyUSDT

Two key points in this table warrant attention. First, payouts are structured as a revenue split denominated in USDT rather than native tokens, making the design less susceptible to token price volatility. Second, access to trading capital relies on a "one-time evaluation fee" model rather than personal capital allocation. Note that the metrics listed in the table—such as 150+ countries, over $50M funded, and over $3B volume—are self-reported figures published by the company and have not undergone third-party auditing. This context applies across this article.

Given this setup, where lies the value proposition that justifies paying an evaluation fee? Let’s examine the underlying trading architecture next.

Designed as a Crypto-Centric Prop Firm

The core appeal of SizeProp is that it is not merely a conventional prop firm that happens to "handle" digital assets; rather, its trading environment, evaluation rules, and reward structures are tailored to the practical realities of crypto traders.

The trading foundation relies on the order books of Hyperliquid and Trade.xyz. Rather than repurposing legacy platforms built for Forex or equities, SizeProp utilizes a proprietary terminal designed for crypto perpetuals, supporting over 150 pairs including BTC, ETH, and SOL. That said, practical usability is dictated less by the UI and more by order book depth and slippage. Executing large lot sizes on thin books causes execution prices to deviate from displayed rates, directly eroding daily PnL. Pragmatically, users should start with minimum lots to verify whether the order book can absorb their intended position sizes.

On the reward side, a profit split of 80% to 95% is established based on the chosen product, with earnings processed on the same day in USDT. While the company states it has a "zero payout denial history," this represents performance achieved up to the present. The structural requirement to satisfy specific terms—such as maximum drawdown and daily loss limits—before qualifying for a payout remains identical to other industry alternatives.

The relative "flexibility" of the evaluation rules is a primary differentiator highlighted by SizeProp. They have removed minimum trading days, time constraints, and consistency rules enforced by many legacy prop firms, allowing traders to progress at their own pace. Thinking critically, one must ask why competitors impose these constraints in the first place. Consistency rules and minimum trading days serve as mechanisms to filter out traders who pass purely by chance via a single, maximum-leverage gamble. By removing these, SizeProp may balance its risk equations elsewhere—such as through order book slippage, more stringent drawdown assessments, or the evaluation fees collected from unsuccessful applicants. While not conclusive, users should avoid assuming "flexible rules = structurally advantageous" and instead remain aware of where the risk has been transferred.

Furthermore, the fact that Igloo Inc. (the operator of Pudgy Penguins) led the Pre-Seed round provides a layer of brand credibility uncommon among unverified prop firms. The tangible outcomes of this institutional backing are discussed in the following section.

Fee Structure and How to Start the Challenge

Fees for SizeProp operate on a "one-time payment" basis, with the foundational premise that fees are non-refundable if the user fails the evaluation. Products are categorized into three types based on entry price and evaluation phases, making it essential to understand the distinctions beforehand.

ProductPhasesStarting Price (Approx.)Target User
Degen1-StepFrom $33Traders looking to test the prop model at the lowest entry cost
1-Step1-StepFrom $61Traders seeking to test under slightly stricter conditions than Degen
2-Step2-StepFrom $50Traders accustomed to industry-standard two-phase evaluations

Account sizes can be selected from multiple tiers: $5K / $10K / $25K / $50K / $100K, with the maximum $100K representing the cap for premium plans. Payment options include traditional cards, Apple Pay, and Google Pay, alongside crypto options such as USDT, USDC, BTC, ETH, and SOL. Using the promo code "IGLOO" applies a 10% discount on evaluation fees; however, since it is not explicitly stated whether this is permanent or time-bound, verify that the discount reflects accurately on the checkout screen.

The operational steps to get started are as follows:

  1. Register an account on the official website (sizeprop.com).
  2. Select an account size and product aligned with your risk tolerance (starting with lower-tier plans like Degen is recommended).
  3. Process the evaluation fee, entering the promotional code if applicable, to initiate the challenge.
  4. Trade perpetual futures via Hyperliquid / Trade.xyz, targeting profit milestones while complying with drawdown parameters.
  5. Upon passing, operate via a funded account and withdraw profits in USDT.

One final element to verify prior to registration is the drawdown calculation method. Because maximum drawdown is measured against "unrealized PnL (including open losses)," short-term volatility or a single wick that triggers stop-hunting can instantaneously degrade margin maintenance ratios, hitting the threshold and resulting in immediate disqualification. Because parameters shift depending on the specific product and account size, moving forward on assumptions can cause users to lose their passing status.

While the upfront cost of evaluation fees is a consideration, joint campaigns and established institutional backing exist to support the platform’s operational footprint.

Capital Raising and Pudgy Penguins Integration

SizeProp itself has not issued a native token or announced an airdrop. However, a relevant incentive opportunity materialized via a joint initiative with Pudgy Penguins called the "SizeProp x Pudgy Penguins Open Prop Trading Competition," which commenced on April 2, 2026. This global event required no NFT ownership or pre-existing affiliation; participants purchased a $100K account evaluation challenge to compete on a real-time leaderboard.

On the corporate financing side, SizeProp launched in October 2025 under founder Windra Thio and announced the closing of a Pre-Seed (SAFE) round led by Igloo Inc. in May 2026. The funding amount remains undisclosed, with capital allocated toward scaling infrastructure dedicated to crypto prop trading. As the operating entity behind Pudgy Penguins, Igloo Inc.’s investment provides SizeProp with brand credibility and marketing conduits such as the aforementioned trading competition. Conversely, this indicates that SizeProp's present credibility relies substantially on its institutional backing rather than an extensive, independent operational track record, which remains in its early stages of development.

Before participating, it is vital to assess the associated risks, ordered below by operational relevance.

Core Risks to Understand Before Participating

The primary misconception to discard is that "not risking personal trading capital equals zero risk." Evaluation fees are non-refundable upon failure, meaning multiple attempts result in compounding out-of-pocket costs. This expenditure should be viewed not as a trading loss, but as an upfront sunk cost required for participation.

Second is the specific risk of disqualification inherent to prop firms. Violating maximum drawdown or daily loss thresholds results in the immediate forfeiture of the account and accumulated profits, irrespective of trading skill. Crypto perpetual markets exhibit high volatility; sharp price movements or sudden wicks during low-liquidity hours can rapidly compromise margin maintenance ratios and trigger breaches. Traders must manage leverage prudently to ensure their methodologies do not breach platform constraints.

Third is the operational risk tied to SizeProp's status as a newly launched service. Long-term payout stability, potential amendments to terms of service, and structural longevity are variables that require verification over time. Furthermore, because trading occurs via perpetual futures on Hyperliquid / Trade.xyz, users remain exposed to broader derivatives risks including liquidations, slippage, and oracle deviations during periods of market stress.

Additionally, consider regional regulatory variances (the legal treatment of perpetuals and prop trading varies significantly by jurisdiction; residents of certain regions must independently verify domestic financial regulations and tax compliance), the absence of a native token or confirmed airdrop, and the need to manually verify the application of the "IGLOO" promo code at checkout.

👉 Review Terms of Service and Prohibited Strategies

Evaluating these risks highlights a clear distinction between traders suited for SizeProp and those who are not.

Who is This Platform Suited For?

SizeProp is ideally suited for traders who possess established experience in perpetual markets and maintain disciplined stop-loss and margin management habits. For individuals looking to exchange an upfront evaluation fee for access to leveraged, funded capital—rather than depositing substantial personal assets—this model presents a viable option. The distribution of payouts in USDT is similarly advantageous for those seeking to secure returns in stablecoins.

Conversely, the platform is not recommended for individuals who lack a comprehensive understanding of leverage, drawdown mechanics, and liquidation structures. It is likewise unsuitable for anyone utilizing capital that would impact their financial stability if lost, or those unable to verify local regulatory and tax implications. Because this platform is not designed around guaranteed incentives or casual participation, it serves best as a utility for disciplined traders capable of executing consistent strategies within strict risk guidelines, rather than casual users looking for quick turnarounds.

Summary

SizeProp is a proprietary trading firm tailored for crypto perpetual markets. By leveraging the infrastructure of Hyperliquid and Trade.xyz to grant funded accounts to successful challenge applicants, its structure differs fundamentally from conventional exchanges or speculative airdrop campaigns. Its backing by Igloo Inc. provides a distinct capital and branding foundation among early-stage prop firms.

The platform offers a trading architecture built around the needs of crypto participants, USDT profit allocations, and an evaluation framework with fewer traditional constraints. However, this flexibility demands an awareness that risk parameters may be accounted for elsewhere in the ecosystem. Evaluation fees are sunk costs, and drawdown parameters mean abrupt market volatility can lead to rapid disqualification.

In conclusion, SizeProp should be approached strictly as a structured prop trading opportunity rather than an incentive campaign. An ideal entry strategy involves utilizing a lower-tier plan, such as Degen, to test whether your trading strategy aligns with platform rules, confirming local regulatory compliance, and committing only evaluation fees that fit within your established risk tolerances.
