SizeProp

SizeProp review: SizeProp is a crypto-native proprietary trading evaluation firm launched in 2025 and operated through SIZ EDU Limited in the Cayman Islands. Current products include Degen, 1-Step and 2-Step structures, with static maximum drawdown under the current rulebook, no consistency rule, no normal evaluation time limit and crypto-focused market access.

PFB reputation update — 15 September 2026: SizeProp is now rated 63 / 100 with Moderate status. Its current trading rules are reasonably clear and the firm has a meaningful X presence, but a short operating history is not enough for PFB Verified. SizeProp's current Withdrawal Policy also gives the company broad discretion over reward approval, which remains a material trust deduction. Any older 69/100 or PFB Verified references are superseded by this audit.

Bridge Verdict Preview

SizeProp remains a relatively strong Moderate crypto prop firm from a rule-design perspective. The main issues are evidence maturity and payout-contract discretion rather than hidden challenge math.

TL;DR

• Best for: crypto traders who prefer static drawdown, no consistency and no normal evaluation deadline.
• Biggest strength: simple current risk structure with balance-calculated/equity-enforced limits.
• Main trust limitation: short operating history, small independent review sample and discretionary reward language.

SizeProp at a Glance

Independent review verification: The Prop Firm Bridge research team independently fact-checks this SizeProp review against current public rules, account terms, pricing, payout information and official firm materials available at the time of review. Where a coupon code appears on this page, checkout applicability is checked separately before it is described as verified. Last reviewed in 2026.

SizeProp receives 63/100 — Moderate after PFB's September 2026 reputation-depth audit. The rules themselves score well, but PFB now requires materially deeper independent reputation evidence before awarding Verified status.

Who This Prop Firm Is For (and Not For)

SizeProp is best for crypto traders who value static drawdown, no consistency rule and no fixed evaluation deadline. It is less suitable for traders who want a long payout record or a contract that makes rewards fully mechanical rather than discretionary.

Risk Profile Compared to Industry Standards

Current challenge mechanics are competitive, but the payout-policy language and young reputation record are more important trust constraints than the numerical drawdown percentages.

PFB Verification Signal

SizeProp has a real public presence and current rules, but its short operating history limits the evidence available for PFB Verified. PFB also treats the Withdrawal Policy's discretionary language as a material risk factor.

Pros & Cons

SizeProp is a crypto-native proprietary trading evaluation platform launched in October 2025 and operated by SIZ EDU Limited in the Cayman Islands. Traders pay a one-time evaluation fee for access to a simulated account, attempt to reach the selected profit target without breaching the daily-loss or static maximum-drawdown rules, and can become eligible for a funded performance-reward account after passing.

For high-intent queries such as SizeProp review 2026, is SizeProp legit, SizeProp scam, SizeProp payout, SizeProp payout denied, SizeProp rules, SizeProp drawdown, SizeProp daily loss reset, SizeProp pricing, SizeProp Hyperliquid, SizeProp consistency rule, SizeProp KYC and SizeProp refund, the current legal documents are just as important as the attractive trading rules. SizeProp's evaluation framework is genuinely simple; its Withdrawal Policy gives the company materially broader payout discretion than the top-ranked crypto firms.

Prop Firm Bridge rates SizeProp 69/100 — PFB Verified. That score places it only slightly above PFB's Trusted threshold because two very different evidence profiles coexist. The trading side is strong: static maximum drawdown, no consistency rule, no minimum trading days and no standard evaluation deadline. The payout-contract side is weaker: rewards are discretionary, eligibility does not guarantee approval, and the company reserves broad authority to approve, deny, delay, reduce or cancel a reward request.

What Is SizeProp and Who Operates It?

SizeProp is a crypto-first evaluation platform publicly associated with co-founder Windra Thio. Its current legal policies identify SIZ EDU Limited in the Cayman Islands as the operator. The company launched in October 2025 and has marketed institutional backing, including a pre-seed round led by Igloo Inc.

The formal legal framing is unusually explicit. SizeProp is not a broker, does not accept customer deposits and does not give traders ownership of a live trading account. The current Terms and AML/KYC Policy say all user trades occur solely in a simulated environment and that no user order is executed, routed, mirrored, offset, cleared or settled on a live market or blockchain.

This point corrects a common semantic misunderstanding created by phrases such as “powered by Hyperliquid.” SizeProp can use Hyperliquid-related market infrastructure or data while the user's trading account remains simulated. “Hyperliquid-powered” does not mean the trader personally sends live orders to Hyperliquid.

Evaluation Models & Account Types

The current SizeProp product family includes Degen, 1-Step and 2-Step. All three currently use static maximum drawdown and have no consistency rule, no minimum trading days and no standard evaluation deadline.

SizeProp Degen Rules

Degen uses an 8% profit target, 2% daily loss and 3% static maximum drawdown. The structure is simple but extremely tight. A 3% total loss allowance leaves almost no room for a strategy with normal crypto variance.

Older May 2026 SizeProp marketing described Degen as a very low-cost entry route, including a $19 $5K tier and a much lower $100K fee than today's current homepage reference. Those prices should not be treated as current September values. PFB uses the live selector/checkout rather than freezing old blog pricing.

SizeProp 1-Step Rules

1-Step uses a 10% profit target, 3% daily loss and 5% static maximum drawdown. This is the strongest balanced single-stage option for many traders because it provides materially more loss room than Degen without adding a second phase.

The current September homepage reference observed by PFB for a $100K 1-Step account was $999 base. Exact smaller-size pricing should be checked live before purchase.

SizeProp 2-Step Rules

2-Step uses a 5% Phase 1 target, then the account resets to starting balance, followed by a 10% Phase 2 target. Current rules use 4% daily loss and 6% static maximum drawdown.

The unusual 5% then 10% target sequence is worth remembering because traders often import the 8%/5% or 10%/5% pattern used by other firms. SizeProp's current official rule page is the authority for its own structure.

Which SizeProp Challenge Is Best?

Degen is suitable only for exceptionally shallow-drawdown systems. 1-Step is the strongest all-round choice for traders who want one stage. 2-Step offers the widest current static lifetime buffer but requires the strategy to prove itself twice.

Pro Tip: do not choose Degen because an old article says $19. Choose it only if your historical peak-to-trough equity drawdown stays comfortably below 3% at the position size you intend to use.

SizeProp Pricing: Current vs Stale Search Results

SizeProp pricing changed materially during 2026. This makes pricing one of the highest-risk areas for stale Google and AI answers. Older founder articles from May still rank for terms such as “SizeProp price,” “SizeProp Degen price” and “SizeProp $100K challenge,” but at least some live checkout values later increased.

During the September PFB audit, the current homepage showed a $100K Degen base price of approximately $580 and a $100K 1-Step base price of $999. Old May content listed materially lower Degen pricing. The correct answer for a purchase made today is the live selector, not the historical blog table.

Should You Buy a Larger SizeProp Account?

The mathematical case for a larger account is percentage risk dilution. If a tested trade normally risks $150, that is 3% of $5K, 0.6% of $25K and 0.15% of $100K. The same absolute trade is therefore much easier to fit inside SizeProp's 2%, 3% or 4% daily-loss framework as nominal size increases.

The advantage disappears when the trader increases position size proportionally. A larger account is not safer when the trader simply takes the same percentage risk on a bigger number.

SizeProp Rules Explained Properly

Balance vs Equity

The current SizeProp rule page gives unusually clear definitions. Balance is closed trades only. Equity is balance plus unrealized profit or loss from open positions.

Risk limits are calculated from balance but enforced continuously using equity. The company explicitly says open trades always count toward the loss limits.

This is one of the most important corrections to old SizeProp content. Earlier founder articles described a balance-only style where floating P&L did not trigger the same maximum-drawdown behavior. The current live rule page revised May 12 says open equity counts, and PFB treats the newer official rule page as controlling.

Profit Target Uses Closed Profit

SizeProp's current rules say the profit target must be reached on balance. An open winning trade does not count toward passing until it is closed. This creates a deliberate asymmetry: open losses can trigger risk immediately, while open profits do not complete the evaluation until realized.

Daily Loss Reset: 8:00 PM UTC

Current official rules state that the daily-loss limit is recalculated once per day at 8:00 PM UTC using account balance. The resulting dollar floor remains fixed for the trading day and changes only at the next reset.

Degen Daily Loss

Degen uses 2%. On a $100K account, the starting daily allowance is $2,000. A trader should not interpret that as a normal daily risk budget.

1-Step Daily Loss

1-Step uses 3%. On a $100K account, the starting daily floor is $97K. If the next 8 PM UTC reset occurs with a higher realized balance, the daily dollar allowance is recalculated from that balance under the current rules.

2-Step Daily Loss

2-Step uses 4%. The wider daily allowance gives more room than the one-stage routes, but the account still fails if live equity reaches the active floor at any point.

Why Old 04:00 or 00:00 UTC References Are Stale

Older indexed SizeProp material can show different daily reset times. The current live rule page says 8:00 PM UTC. Search engines and AI assistants can repeat the older time unless the review explicitly distinguishes current rules from historical articles.

Static Maximum Drawdown Explained

Current SizeProp maximum drawdown is static from starting balance: 3% Degen, 5% 1-Step and 6% 2-Step. A static floor does not move upward as the account makes profit.

Degen Example

A $100K Degen account has a $97K lifetime floor. If the account grows to $110K, the floor remains $97K.

1-Step Example

A $100K 1-Step account has a $95K lifetime floor. If realized balance grows to $108K, the lifetime floor remains $95K.

2-Step Example

A $100K 2-Step account has a $94K lifetime floor throughout both phases under the current simplified rule page. The account resets to starting balance before Phase 2, but the 6% static structure remains defined from the starting balance.

Static Does Not Mean Floating Loss Is Ignored

The drawdown level itself is fixed, but live equity is what is tested against it. A $95K floor can be breached by an open position even when the closed balance remains above $95K.

No Consistency Rule

Current official rules explicitly say SizeProp has no consistency rule. There is no 20%, 30%, 40% or 50% best-day percentage under the current core evaluation rules.

This can fit crypto strategies whose returns naturally arrive in bursts. A strong BTC trend day can contribute most of the target without creating a separate profit-distribution objective.

No consistency rule should reduce unnecessary trading. A trader who reaches the target can stop; they do not need to dilute a winning day.

No Minimum Trading Days

SizeProp currently requires no minimum number of trading days. A trader does not need to place filler trades after reaching the target.

This is a material advantage over firms where a trader can hit the target and then lose the account while completing a mandatory day count.

No Standard Evaluation Time Limit — But a 90-Day Activity Rule

There is no maximum calendar deadline to reach the target. However, current rules require at least one trade every 90 days to keep the account active.

That distinction matters for voice-search questions such as “Does SizeProp expire?” The evaluation target does not expire after a fixed number of days, but prolonged complete inactivity can still affect the account.

Funded Stage: What Actually Changes?

After passing, the profit target disappears and the trader becomes eligible for a funded performance account. Current rules say funded accounts follow the same daily-loss and maximum-drawdown framework as evaluations.

The legal documents make a crucial point: the funded account is still simulated. The current Terms say no user trades are executed, routed, mirrored, offset, cleared or settled on any live market or blockchain. Any independent treasury or risk-management activity belongs solely to SizeProp and is not linked to user trades.

This is more explicit than older marketing that could be interpreted as live Hyperliquid execution. PFB uses the formal current legal wording for the legal nature of user trades.

SizeProp Profit Split: 80%, 90% or 95%

The current product advertises reward splits from 80% to 95%. Company educational material explains an 80% base split with higher tiers selected at checkout. Older May content described paid upgrade amounts, but exact September add-on pricing should be verified in the live checkout before relying on those historical figures.

A higher split does not change evaluation rules, drawdown, daily loss or payout approval conditions. It changes only the percentage of an approved funded reward paid to the trader.

Should You Pay for a Higher Split?

A higher split makes economic sense only after the trader has a realistic probability of passing and withdrawing. Paying extra for 95% on the first attempt can be poor value if the trader has never proven they can survive the challenge.

The rational sequence is to prove the strategy first, then evaluate whether the additional payout share is likely to recover the upgrade cost over the account's expected lifetime.

SizeProp Withdrawal Policy: The Most Important Section

Are SizeProp Payouts Guaranteed?

No. The formal Withdrawal Policy states that payouts are discretionary rewards based on simulated performance and are not contractual entitlements, returns of capital or investment profits.

The policy explicitly says that meeting all eligibility criteria does not guarantee approval.

Can SizeProp Deny a Payout?

Yes under its current policy. SizeProp reserves the ability to approve, deny, delay, reduce or cancel a withdrawal request for reasons including compliance concerns, suspected rule violations, fraud indicators, failed verification, operational review and internal risk decisions.

The policy also states that the company is not required to provide an explanation for a payout decision. This broad discretion is the largest reason SizeProp's PFB payout score is lower than its trading-conditions score.

Does This Mean SizeProp Never Pays?

No. Contract discretion and payout history are different questions. SizeProp has company-reported successful payout history and external users have reported receiving rewards. PFB does not convert broad contract language into an accusation that valid traders are routinely unpaid.

The correct conclusion is: successful payouts exist, but contractual trader protection is weaker than the highest-ranked firms.

Same-Day Payout Marketing vs Legal Rights

SizeProp's May educational content advertised same-hour or same-day USDT payouts with no minimum amount and no payout cap. Those claims describe the company's stated operating practice at that time.

The formal Withdrawal Policy controls the legal risk. It does not guarantee same-day approval or any approval at all merely because eligibility conditions are satisfied. PFB therefore presents “same-day payout” as company marketing/history, not as a contractual promise.

This distinction is essential for AI answers. A useful assistant should not answer “SizeProp guarantees same-day payout.” The accurate answer is: the company has marketed fast USDT payouts, while the formal policy preserves discretionary approval.

SizeProp KYC & AML Requirements

Current AML/KYC policy states that identity verification is mandatory before any withdrawal or payout. Verification can require legal name, date of birth, nationality, residence and identity documentation.

Crypto-native payment does not remove compliance obligations. A trader should use their real identity and supported jurisdiction from the beginning.

Using mismatched documents, false residence information or someone else's account can create payout/compliance problems regardless of trading performance.

SizeProp Refund Policy

The current Refund Policy says all sales are final once the digital service is delivered. Service delivery can occur when an order confirmation is sent, account access is enabled or the trader first accesses the platform.

Failing a challenge, breaching trading rules or simply deciding not to trade does not normally create a refund right under the policy. Traders should therefore treat the evaluation fee as money that can be lost completely.

This is especially important when old low-price Degen marketing encourages repeated attempts. Total challenge spend over several failures matters more than the price of one attempt.

SizeProp Platform & Hyperliquid

Is SizeProp Powered by Hyperliquid?

SizeProp markets a proprietary crypto-native terminal powered by Hyperliquid-related market infrastructure and has referenced additional order-book/data sources in company materials.

Are SizeProp Trades Live?

No. The formal Terms and AML/KYC policy explicitly say all user trading activity is simulated and no user trades are executed, routed, mirrored or settled on a live market or blockchain.

This is one of the most important accuracy clarifications for the review. Live market data and a Hyperliquid-powered interface do not make the user's orders live Hyperliquid orders.

Execution, Fees & Slippage

Even in a simulation, spreads, fee modeling, slippage and funding can affect equity and strategy expectancy. Traders should test the platform before scaling because risk limits are enforced live using account equity.

Leverage

Leverage and instrument availability can change by product and market. PFB does not freeze an old leverage table when the current live terminal can be checked directly. Position sizing should be based on the loss limits, not the maximum leverage available.

Bots, Automation & Prohibited Strategies

Older founder content described browser-level automation such as TradingView alerts or clicker scripts as supported while direct API automation was intentionally unavailable. The formal Terms also contain broad provisions against latency exploitation, platform-bug abuse and simulation-specific strategies.

Because automation guidance can evolve, PFB does not convert an old blog statement into a permanent “bots allowed” field. Traders whose strategy depends on automation should obtain written current confirmation for the exact method before purchasing.

SizeProp Payout Evidence & Trader Feedback

Company material from May reported 100+ payouts, a largest payout above $8,500 and zero denied payouts at that time. PFB treats those as company-reported historical statistics, not an audited guarantee of present or future performance.

External reviews at the September audit were generally positive but not uniformly so. Successful payout reports coexist with criticism of payout discretion and delays. One useful type of evidence is a review that documents a problem and later records resolution, because it shows how support handles a dispute rather than only whether a happy trader left five stars.

SizeProp Reviews, Reputation & Legitimacy

Is SizeProp Legit?

Based on evidence available on 14 September 2026, PFB rates SizeProp 69/100 — PFB Verified. The operator is identifiable, the product is active, the current trading rules are clear and successful reward evidence exists.

The score remains cautious because the company is young and the Withdrawal Policy gives it unusually broad discretion over rewards.

Is SizeProp a Scam?

PFB found no basis to label SizeProp a scam. The accurate concern is contractual: a trader can satisfy eligibility conditions without having a contractual entitlement to payment under the current policy.

What Is SizeProp's Biggest Risk?

The biggest non-trading risk is payout discretion. The biggest trading risk depends on plan: Degen's 3% maximum drawdown is exceptionally tight, while 1-Step and 2-Step provide more room.

SizeProp vs Breakout Prop

Breakout ranks far higher at 91/100 because of Kraken ownership, stronger payout-contract confidence, a larger public operating history and current on-demand payout mechanics. SizeProp's pure evaluation rules are competitive, but its legal reward discretion creates a large trust gap.

SizeProp vs HyroTrader

HyroTrader scores 88 and has operated since 2022. SizeProp has simpler qualification mechanics—no consistency and no minimum days—while HyroTrader has the stronger maturity and exchange-connected operating record.

SizeProp vs Hypernova

Hypernova scores 86 and provides stronger current public payout-reserve and on-chain settlement infrastructure. Both are transparent that user accounts are simulated, but Hypernova's reward architecture is more programmatic while SizeProp's legal policy retains broader company discretion.

SizeProp vs Carrot Funding

Carrot scores 72 and uses a more complex HWM/consistency framework but publishes strong transaction-level on-chain proof. SizeProp has cleaner static/no-consistency evaluation rules but weaker contractual payout protection.

Voice Search: Direct SizeProp Answers

“Is SizeProp legit?”

PFB rates SizeProp 69/100 and PFB Verified. It is an active Cayman-operated simulated trading evaluation business with clear current risk rules and successful payout evidence, but broad payout discretion lowers the score.

“Does floating loss count on SizeProp?”

Yes. Current official rules say all limits are enforced in real time using equity and open trades always count.

“Is SizeProp drawdown static or trailing?”

Current Degen, 1-Step and 2-Step maximum drawdown is static at 3%, 5% and 6% respectively.

“When does SizeProp daily loss reset?”

Current official rules say 8:00 PM UTC.

“Does SizeProp have a consistency rule?”

No. Current official rules explicitly say there is no consistency rule.

“Does SizeProp have minimum trading days?”

No. Current evaluations have no minimum trading-day requirement.

“Can SizeProp deny a payout?”

Yes under the current Withdrawal Policy. Payouts are discretionary rewards and meeting eligibility criteria does not guarantee approval.

“Are SizeProp trades live?”

No. Current Terms and AML/KYC policy say user trades are simulated and are not executed, routed or mirrored to a live market.

“Does SizeProp require KYC?”

Yes before any payout or withdrawal. The AML/KYC policy describes identity verification as mandatory and non-negotiable for payout processing.

“Can I get a refund from SizeProp?”

Current policy says sales are final once the digital service is delivered. Challenge failure or rule breach normally does not create a refund right.

Common SizeProp Mistakes

Believing Old Balance-Only Content

Current rules say live equity counts. Open loss can breach the account.

Using the Wrong Daily Reset Time

Current rule page says 8:00 PM UTC. Older indexed times can be stale.

Buying Degen Because of Old $19 Marketing

Historical pricing can remain indexed even after the live checkout changes. More importantly, Degen's 3% total drawdown is a difficult risk structure.

Assuming No Consistency Means Guaranteed Payout

Evaluation qualification rules and payout-contract rights are separate. The Withdrawal Policy retains discretionary approval.

Confusing Hyperliquid-Powered With Live Execution

Current legal documents say all user trades are simulated and not routed or mirrored live.

Paying for a Higher Profit Split Before Proving the Strategy

A 90% or 95% share is valuable only after the trader reaches approved funded payouts.

Final Buying Checklist for SizeProp

Before paying, confirm Degen / 1-Step / 2-Step, current live price, account size, target, daily-loss percentage, static maximum drawdown, 8 PM UTC reset, equity enforcement, no-consistency rule, zero minimum-day rule, 90-day activity rule, selected profit split, KYC requirements, supported jurisdiction, automation permission, stablecoin payout rail, current Withdrawal Policy and Refund Policy.

Save the current rules and policies at the time of purchase. If a support agent confirms a rule that materially affects payout or automation, keep the written response.

Conclusion

SizeProp earns a 69/100 PFB Score because the challenge rules are stronger than the payout contract. Static drawdown, no consistency, no minimum days and no standard deadline make the evaluation itself attractive. The formal Withdrawal Policy materially reduces the overall rating because reward approval remains discretionary.

1-Step is the best balanced route for many traders. Degen should only be used by very low-drawdown strategies. 2-Step provides the widest current static risk buffer but requires two targets. Every prospective trader should read the Withdrawal Policy, AML/KYC policy and Refund Policy before paying.
