SPYx Premium Narrows to 0.44 bps Amid Price Source Disparity
Tokenized SPY instrument shows minimal deviation from reference price despite 54 bps spread between DEX aggregators and primary pools
Summary
SPYx trades at a 0.44 basis point premium to the SPY reference price with $4.54M in 24-hour volume against $4.33M in liquidity. The top five holders control 67.9% of the 95,779 token supply. A 54 basis point price discrepancy exists between Jupiter ($772.08) and the top DEX pool ($776.24), indicating market fragmentation.
Why it matters
The narrow premium demonstrates effective arbitrage mechanisms for tokenized equity exposure, while holder concentration and price source variance highlight liquidity and pricing risks.
Key observations
SPYx trades at +0.4bps versus the SPY reference price.
premium_bps = 0.4 bps (baseline -0.654)
Circulating supply is 95,779.21 tokens (+0% vs the prior observation).
supply_ui_amount = 95,779.21 tokens (baseline 95,779.21)
Tracked DEX liquidity totals $4,326,149 across 30 pools.
liquidity_usd = 4,326,149 USD (baseline 4,320,104)
The five largest token accounts hold 67.9% of supply (pools and custodial accounts included).
top5_account_share = 0.679 ratio (baseline 0.679)
24h DEX volume of $4,535,770 implies 1.05x turnover of pooled liquidity.
volume_24h_usd = 4,535,770 USD
Thesis
SPYx maintains tight tracking to its SPY reference with minimal premium deviation, though price source dispersion and high holder concentration present structural considerations.
Claims
- Factconfidence 100%
SPYx trades at a premium of 0.44 basis points to the SPY reference price of $772.05.
- Factconfidence 100%
The DEX pool price of $776.24 exceeds the Jupiter aggregator price of $772.0839712330671 by approximately 54 basis points.
- Calculationconfidence 100%
The 24-hour trading volume of $4,535,770.05 represents a 1.05x turnover ratio relative to current liquidity of $4,326,148.97.
- Factconfidence 100%
The top five token accounts hold 67.90% of the total supply of 95,779.21 tokens.
- Hypothesisconfidence 50%
Supply has remained stable at 95,779.21 tokens throughout the 7.2-hour baseline period, with variation limited to the eighth decimal place.
Would falsify this: supply_ui_amount changing by more than 0.1% in subsequent observations
- Hypothesisconfidence 50%
The premium has oscillated between -9.38 and +10.40 basis points over the preceding 7.2 hours, indicating active arbitrage but potential volatility in tracking efficiency.
Would falsify this: premium_bps remaining static for extended periods premium_bps exceeding ±15 bps
- Factconfidence 100%
Hourly transaction volume of 998 and 24-hour volume of 22,249 transactions demonstrate sustained market activity across 30 trading pairs.
- Hypothesisconfidence 50%
The minimal 24-hour price change of -0.136% combined with the narrow current premium suggests low tracking error relative to the underlying SPY reference asset.
Would falsify this: price_change_24h_pct exceeding ±1% premium_bps diverging beyond ±5 bps

- Sources that failed during collection are recorded, not imputed
Comparison window: Stored observation history for this asset
Confidence rationale
Confidence is computed from source coverage, cross-venue agreement, baseline depth, and independent verification. This run scored 0.66 (moderate).
Limitations
- Price source dispersion of 54 bps between DEX aggregators and primary pools may indicate liquidity fragmentation or stale pricing data.
- Top five holder concentration of 67.9% includes pool and custodial addresses, limiting interpretability of distribution metrics.
- Baseline liquidity data contains null values for 14 of 24 observations, reducing confidence in liquidity trend analysis.
- Transaction counts (txns_h1, txns_24h) lack size distribution data, preventing assessment of average trade magnitude.
- The 7.2-hour baseline period may not capture longer-term premium volatility patterns or cyclical market behaviors.
- Absence of failed source reporting limits understanding of potential data gaps or exchange outages.
- Largest-account concentration includes liquidity pools and custodial accounts; it is not a beneficial-owner distribution.
