What changed

Over roughly three and a half hours, observed TVL increased from $17,909.95 to $28,228.37 while the displayed APY stayed at 10.00%. IPOR Fusion's current interface shows the same Apple Carry Trade at +10.00% APY with TVM of 35.4 AAPLc, indicating a material difference in units, accounting scope, or update timing versus Portals' USD TVL figure.

Why it matters

A sharp TVL increase without a higher displayed APY points to accelerating inflows into the Carry Vault rather than a temporary headline-yield spike. The absolute vault size remains small, however, and the Portals and IPOR Fusion figures do not reconcile directly, so persistence and methodology differences need further observation. The yield source is the tokenized-stock carry strategy operated by TAU Labs on IPOR Fusion, whose public interface shows a 10% target/displayed rate.

Evidence

  • Portals Explorer — TAU AAPLc Carry Vault — Observed TVL was $28,228.37 with displayed APY of 10.00%. The same public page had been observed at 00:27 JST on 2026-09-12 at $17,909.95 TVL and 10.00% APY. 2026-09-12T03:53:37+09:00
  • IPOR Fusion — Stocks / Apple Carry Trade — Apple Carry Trade is displayed at +10.00% APY with TVM of 35.4 AAPLc. This does not directly reconcile with Portals' USD TVL figure, suggesting differences in accounting scope, definitions, or update timing. 2026-09-12T03:53:37+09:00
  • Portals.fi — DeFi TVL September 2026 Week 1 — The article recorded TAU AAPLc Carry Vault at 10.00% APY and $9.67K TVL, providing an earlier public baseline for the vault's growth during September. 2026-09-12T03:53:37+09:00

Limitations

The Portals vault page is a live view, so historical point-in-time values may not remain reproducible at the same URL. The cause of the inflow was not independently verified and cannot be attributed to Spectra or another specific service. IPOR Fusion's TVM display differs from Portals' TVL, and differences in accounting scope, definitions, or update timing remain unresolved. Reward budget and end conditions were not independently confirmed. The vault remains small in absolute terms and carries smart-contract and strategy risk as well as AAPLc issuer, custody, redemption, and eligibility risks.
