XYZ Thesis Assessment

RESOLVED YES with Brier score 0.0196, near-perfect calibration. Block delivered +24% GP growth, substantially exceeding the 15% threshold. The ensemble's 86% confidence was well-calibrated and directionally correct. This resolution confirms the 4th consecutive quarter of GP acceleration (Q1 +9%, Q2 +14%, Q3 +18%, Q4 +24%) and validates the DISCONNECTED narrative-reality gap assessment. The result exceeded not just the threshold but most model expectations, suggesting the ensemble may have been moderately conservative. The GP acceleration pattern is now the strongest evidence point in the thesis; four quarters of improving growth against a declining stock (prior to this earnings) is rare for a $40B+ company.

RESOLVED YES with Brier score 0.1024, adequate but less precise calibration. Block delivered +10.3% GPV growth, barely clearing the 10% threshold. The ensemble's 68% confidence was appropriate given the actual result was only marginally above the bar. Notably, this market was flagged as consensusFragile, and the thin margin of clearance validates that fragility assessment. The more informative data point is forward-looking: Q1 2026 QTD GPV through Feb 24 re-accelerated to >12% YoY, and NVA hit +29% in Q4, the strongest year ever. The COMPETITIVE_POSITION trajectory upgrade from NARROWING to STABILIZING is supported by the GPV result plus the re-acceleration signal.

Unchanged at 28%. The Q4 earnings call contained zero mention of the SEC/DOJ investigation, consistent with management's pattern of silence on this topic. No new information was disclosed in the earnings release or transcript. The 10-K was filed concurrently but legal contingency disclosures have not yet been reviewed in human-readable form. This market remains the highest-information-gain item (1.00) in the entire set and the single largest binary risk. The Compliance Cascade scenario (8-15% probability) is neither confirmed nor de-risked. The continued absence of a Wells notice provides incremental but modest comfort; cases can remain open for years without formal enforcement action.

Unchanged at 15%. Management disclosed qualitatively that portfolio losses were 'higher' in December and January due to mix shift toward new cohorts, described as 'higher losses by design.' They asserted that all 2026 cohorts are 'trending below our risk loss targets' as of mid-February, but provided no specific loss rate percentages, no vintage data, and no portfolio balance outstanding. The Q4 earnings call provides no basis for updating this market's probability. Resolution depends on the FY2025 10-K filing (due March 2026), which must contain allowance for credit loss tables. With Borrow originations at +223% YoY, the stakes of this market have increased even if the probability has not; a breach above 3% at this scale would be substantially more consequential than when the market was created.

Unchanged at 12%. Q4 earnings provided no vintage-level data, consistent with the 88% probability of continued non-disclosure. The Cash App Score development introduces a paradox: Block is building credit scoring data sophisticated enough to license to third-party lenders, yet declines to share vintage performance data with its own equity investors. This data paradox deepens the ACCOUNTING_INTEGRITY concern but does not change the probability of disclosure in the 10-K. Resolution still depends on the FY2025 10-K filing. The ensemble's prior assessment that Block would maintain its disclosure posture appears increasingly well-founded.

Unchanged at 30%, though directional pressure may be modestly downward. Q4 results showed Afterpay deepening its integration into the Cash App ecosystem: Afterpay Pre-Purchase launched in February 2026, Pay in Four extended to P2P transactions, and Cash App Score builds on Afterpay data. Zero discussion of goodwill or impairment testing on the earnings call. The integration depth may make standalone impairment testing less likely to trigger, as Afterpay's value is increasingly inseparable from the Cash App commerce ecosystem rather than evaluated on a standalone basis. However, the ~$29B acquisition price against a fundamentally different rate environment maintains meaningful accounting risk.

Unchanged at 9% with the highest model agreement in the set (0.96). The Q4 earnings call confirmed that all Borrow loans are now fully originated through the SFS bank charter, and Block is expanding to new states via SFS. The FDIC approval for nationwide lending remains the strongest institutional endorsement of Block's compliance posture. No new enforcement actions or charter restrictions were mentioned. The 91% probability of no action effectively removes FDIC risk from the active threat matrix, though the expansion to new states adds modest regulatory surface area.

Unchanged at 71%, but the first condition has been met: Q4 2025 MAU was 59M, exceeding the 57M threshold by 2M and returning to growth after a 12+ month plateau. This is a meaningful de-escalation signal for COMPETITIVE_POSITION, as the NARROWING trajectory concern was primarily driven by flat MAU. Management guided low single-digit MAU growth for 2026 and the long term. The market now depends solely on Q1 2026 MAU holding above 57M; with Q4 at 59M and management guiding growth, the probability should increase, though the formal update will come with the next prediction cycle. PBA at 9.3M (+22% YoY) and Cash App Green engagement lifts provide additional confidence in user retention.

Unchanged at 22%. No new litigation developments were discussed on the Q4 earnings call. The case survived dismissal in February 2026, which confirmed sufficient merit to proceed but does not accelerate the timeline toward resolution. The 78% probability of no resolution by year-end means this regulatory overhang persists through the assessment horizon. The class period (Feb 2020 - Apr 2024) predates many of Block's operational improvements, creating a temporal disconnect. This market provides minimal new signal and is the lowest-priority item for thesis reassessment.
